Re: Perpetual Data (SL6 ssh fail)
my two cents worth. We used SL from 4.1 and still have a number of boxes with SL 6.5. There is still a 7.6 running and never updated as the update killed the ability to connect with our network. On of our dislikes is system d and package manager. RH 8 - none of our cad tools worked. A bright spot in the Linux mess is Devuan. A non system D Debian. It works: All of our cad tools work and you can use apt-get and use most Debian applications. Several boxes have gone a year with out a reboot and were shut down for a clean up and restarted. The installation is pretty easy. The only real down side is the add users and groups function is retarded. I told them to just copy SL 6.5 add users and get on with the show. There is a lot of things 6.5 did well but are not in Devuan. >From an industrial vantage point we really miss SL 5.11 and 6.5. We have basiacally abandoned RH and its following. They seam to pick up the worst ideas and go with it. Our security is pretty simple. - don't laugh too hard. We cron to turn off network after 5:30 and turn it back on at 7 AM. This reduces the time hackers have to pound on it. The other thing is that your IP can be long lived unless you reboot your router. We reboot the router before 7 AM and get a new IP. For industrial use Devuan is a good answere. Odd Notes. We hade two Toshiba high end laptops we were ready to junk. After looking at them in detail. We replace the slow 125G HD with a 1 T SSD. Installed the 386 version of Devuan and we have two new laptops. Performance is outstanding. Not like my 8 core machine with 32G ram undr my desk but the performace is acceptable. Compared to the Windows Dog slow boot it is amazing. Everything works. Save a few K bucks. For a couple of CNC machines in the shop we need Windows. Installed VMWare and loaded Windows 10 and you can almost get your second cup of tea while it is booting. Enjoy the conversation and I really miss SL 6.5 but you have to move on or quit. So here I am 80 yeas old and still working. Get up at 5:30, go to the life maintence program at the local hospital work out for an hr. run (fast old folks shuff) for 10 laps, lift 15 in each hand and 120 reps, drive home get fed and work the next 12 hr. The SW development keeps the neurons connected. One of the real sad thing that has happened to our Engineering Comunity is the during the China Virus shut down the students didn't learn much. They are pretty good a running windows but they don't know how anything works or how to connect a scope etc. The isolation is a disaster for the new science / engineers who worked remotely. My contribution is that we hire one or two bright students and teach them the real world applications. I encourage each when they are ready to explore other oportunities. So far we have had 14 young men and ladies find their lifes endever. The comments I get from companies is how does a student get 4 years of engineering experience when they get their Deploma. When I worked at GE one of my jobs was to train new engineers in the art of digital control. The digital engine control (gray box) on side of the CFM56 engines worked well and was certified in 1987. Another condecending Unix / Linux user. By the way my great,great,great grandfather was a Hessian solder and decided he like the country, jumped ship, married a lady and had 12 Children.

perfect chicken egg Alma Web site.
Planning to upgrade a number of WS's to Alma 8.5. I need to ask them a question but their web site says my brouser is too old. So I can't ask them a question about installing Alma 8.5 Since some developers monitor this web page. I was hoping to get a question answered by the back door. Problem: We have a number of GigaByte 970A DS3 Version 2 (black MB) The bios on these MB will not boot from a USB Flash. Most of the stuff on the internet is Noixe. I can load Alma 8.5 minimal but need the full version that will not fit on a DVD. I have it on a USB Flash but it will not boot. Is there there anyway to load alma 8.5 minimal and later update via the internet or ??? to the full 8.5 version. I have asked Gigabyte Support for a specific Bios update to remove the security BS. They are working on finding it ! I know the bios update version number but it does not exist anymore. I would be nice to be able to disable security to install a system and then turn it back on. I guess it too logical. Maybe I should consult Dilbert. Got two new Dilbert books for Christmas - there really a hoot. Reminds me of a place where I used to work. Happy New Year Larry Linder

Need to add ftp to SL 6 machine
This is out of date but due to what is running on box we need to add ftp and yum will not work because it is not supported. It is only available in the obsolete directory. You can get the .iso's but we do not want to reinstall the OS. Any one have an idea how to install ftp. Or how to get the "rpm" for it. Thank You Larry Linder
Disk reliability - and swap out`
There are 25 systems in our shop, all linux based, a linux based server, and synology Disk Station running raid 1. The Disk Station has 12 TB of space. 6 TB per for each raid level. We buy only one brand of disk with the black label. They are typically 1 TB. User boxes has a SSD drive for the OS and a 2 TB disk for the users space and 32 G RAM. and a quad or six core AMD processor. The graphics boxes get a Video card with lots of ram. 3 D rendering on a slow video care wast's a lot of users time. The server has a SSD for the OS and 6 TB for user apps / library /usr/local and /opt. It also has a mirror disk that keeps a copy of the server locally. These systems are on 24 / 7 and accumulate a lot of hours. No matter what the make mechanical disks have a life span. For grins I used to do a post mortum on disk that failed. There were to types of failures, the spring that returns the arm holding the heads cracks. The second type of failure is the main bearings. Newer disk seem to have less of a bearing failure rate. To prevent operational problems we just swap out the disk on each box at about 5,000 to 7,000 hr. The manufacturer says they are good for 10,000 hr. See the fine print in the Waranty, You have to remember this is a money making operation and down time is costly. Backups run at 12:29 and 0:29 in the AM. At the end of the morning back up a copy is sent to a remote site. For security we shut down the network at 6:20 PM, bring it up at 0:01 AM and shut it down after back up is complete. We bring it back up at 6:45 AM. 10 yeas ago we had a fixed IP and the Chineese found it by just continually pounding on the door. The return IP was 4 hops to a city north east of Shanghi. They had installed a root kit on our server, disabled cron. When you changed the passwd to the server a few millisecond later it was sent to china. We got rid of the fixed IP and reloaded all the systems. So when you shout down the network to your provider the next time your start it you get a different IP. We don't give the disks away as they contain a lot of design data, SW,Cad programs, part programs for our mill etc. We donate them to a charity that drills the disks and recycles the rest. Larry Linder
Back UP
Cron is now broken so you can't scehedule reliable backups. This got broken in SL 6.9 worked in SL 6.5. The reason is that it is looking for files from yum. Whot does yum have to do with cron I heav yet to figure it out. Disk like - we date code our disks and when they are over 5000 hr. We swap them out and give toss them. We have had replaced a bunch of disk at one time and 3 years later they all died within a month. They are typically on 24 / 7. We stagger the start up dates by 6 mo. My advise if you don't want to be forever the support team - buy a MAC. The people I have helped get on to a Linux system are not OS smart and I spend a lot of time helping them out. It also looks like it may be a cradel to grave problem. I money is problem there are a lot free Gov. computers available. They are not free its just that you and I have to pay for them with our taxes. I set my wife up with a Linux box and support is seconds away 24/7. She is smart & industrious and just uses mail, OpenOffice, and a photo archive for the grand kids pictures. That is if I expect dinner on time. Have friends and relatives buy a MAC. Then you can plead - ignorance. Regards Larry Linder

Re: Scientific Linux Advice
To support products for 22 years is difficult. Using VMware is a good solution that we have been using for a long time. I even use Win2000 pro for some applications and Dos all under VMWare. The connection to the Linux file system is "samba". Everyone misses the point. The problem is setting up a system the way we want it and the ability to do that after RH 7 is broken! and has some land mines. A function that can wipe out a file system is flawed and cannot be trusted. Fortunately VMware works - we just bought a new VMWare version. Update is painless.

Re: Scientific Linux Advice
As a bunch of dirty finger engineers we have a serious problem with the the path that Linux has taken. Be forwarned that when you migrate to 7 and later the 32 libs are gone and most applications will not work or install. SL 6.9 is also missing a lot of the 32 bit libs and the graphics do not work. This is crude but effective. We have a SL 6.5 server that has been updated to SL 6.9 but still had the 32 bit libs we needed. We just crated a bastard version of 7.6 with 32 bit libs. We did it by the brail method. When the appication complained about a missing lib we added it. The list was initially long but on closer inspection a lot of the error messages are redundant. After a few hours of work our engineering applications installed and worked. This is a blind alley, but it gave us a few years to get a real solution to the problem. Reading between the lines - IBM & RedHat want the users who use independent installations to just go away. They wont say it but actions are pretty hard to gloss over. All you have to do is use Gnome for a while and your finger falls off due to terrible number of clicks to do something simple. We tried Alma, and Rock and they contain the fatel install flwas IBM invented with 7. and up. Alma is just the same as RH 8.x complete with flaws and booby traps. I pointed this out to the Alma people and thy shot the messenger. Never trust the install process in the "custom" world because it is hopelessly broken, it will erase any disk attached even if you tell it not to format it. Can you imagine a 40 Tera byte server - errased and the rebuild from back up. BEFORE you attempt to upgrade you system - YOU BETTER HAVE A BULLET PROOF BACKUP that is NOT Connected . - No BS. The Debian drivatives have a similar problem. If you remove an application for a second time. The C++ toss is never caught and remains active. The next removal it erases all disks attached. How about that for code testing - it compiles without errors - ship it. Damm glad these people never build bridges or control for Aircraft - opps the 737 max 8 is a victum of the sw people don't know how an airplane flys. The sad part is no one up stream gives a " " . Summary: We just updated a number of workstaitions to SL 6.5 and then to 6.9 so we can get our work done. We are evaluating other options, and just loaded a box with BSD to test.

Hard Drive cloning - RH 7 & 8 drivitaves
I have done just what you are talking about. There is still an isidous flaw in the install program. I used the manual / custom to install almaLinux. The problem: When you setup your system manually and tell it not to format a disk but just mount it. It all looks good but when you finish the install all data on all disks is gone. Including the disk with the .iso and two disk containing image of our system. Thank god for a backup on SL 6.5. This same problem exists in Mint 20 and other derivatives after 7.0 Mint is even worse if remove a file from the desk top, reinstall it, remove it and your complete server is erased. In spite of a number of complaints - and examples that can be reproduced no one seems to be concerned. We did not use almalinux 8.3, or RH 8 and derivatives as we did not want to rebuild our server and 20 + workstations. We simply dropped back to SL 6.5 and updated it to 6.9. This is nuts but RH 7, 8 up -> is untrustworthy. Before you shoot the messenger, just try it. Tried to file an install problem with almaLinus users group. Moderator shot messenger - just like the Kids at Fedora. Nice piece of code - that is put in production without test - compiles with out errors - Done. 10 years of work and a lot of money spent and you get a garbage desktop, and a Linux with a dangerous flaw. IBM/RH should be proud of this work. Still lookign for a usable linux. I think the position taken by the labs is wise and 100% correct in light of the test results over the last 8 mo. The only good part is the minimum install and the linux behind the desk top is alive and well. From a command line point of view it works - just like my Convex running BSD 4.2 30 years ago!!!!

Re: In search for a SL replacement - almalinux
You are correct - its a IBM/RH problem. almaLinux is just the receipient A long time ago I used to evaluate Fedora releases - If you offered a suggestion or cited an issue the Kids at Fedora just shot the messenger - problem solved. I just ignored Fedora and assumed it to be a bad joke. I am going to sign up to do testing for "almaLinux", I would like to see it succeed. On the positive side: While we were testing almaLinux we did a minimal install and it was easy, quick, and it all worked. We were able to use it as a headless server without any issues. Its been running for a month with out issue. The real OS behind the Gnome desktop is alive and well. My analysis of the install "option" "partition" is that there is some bad C++ code in the linux world that deals with setting up partitions and directories. This same flaw exists in a number of distrobutions as part of other higher level functions such ad Mint that we evaluated. My guess is that it is a bad throw that is never received and never removed. In Mint when you remove / install / remove an application it erases all files on all mounted disks.

In search for a SL replacement - almalinux
Another linux installation and test. AlmaLinux 8.3 1. The first thing we noticed is that the displays were backward. 2 is on the left 1 is on the right. It maters because when you use VMware and multiple OS - just another pain. 2. When you do an install it all on the right hand monitor and there is no way to change it unless you interchange monitor cables. 3. The network connection, setting up root, and a user was good. 4. We do not use lvm and our setup is a carryover from my Convex Super Computer day. Use the Custom button and then done and you should be able to setup your file system in a minute. This turned out to be the most convoluted exercise I have experienced in a long time. The OS is installed on a SSD and the other three disks are to be mounted but not formatted to preserve the drive contents. As it turns out you are flying blind because there is no disk info. You have to go back to your hex calculator - between your ears - and set up partition sizes. Most of the familiar partitions are gone. The ones you want to preserve have odd sdx numbers as in maybe random. Once this was complete - about 8 hr of dinking with it to try and decode the scheme. The we were able to install almaLinux 8.3 full version. It was pretty quick because we were installing from a local disk. We rebooted, it got hung up on a usb scanner attached to the system. Power down / up and cold boot - like the days of DOS and it finally booted up. Inspecting the directories we found that several mount points were missing and the disks we wanted to mount, no format, to preserve the data were empty. This even included the disk that contained the .iso file we installed from! This is really bull shit code. How can on take a very simple working function that has worked for 20 years and basterdize it to the point of being less than worthless. Does anyone check their work - it compiles without errors - ship it - Why do you hire minions? 5. The next thing was to add users. This has regressed to a exercise in typing skills - hello DOS. The adduser GUI is for a network and was never finished. Another nice piece of code. 6. To be kind to the Gnome desktop - it is another convuleted ugly abortion. To get simple stuff done takes a dozen mouse clicks. You can't easily setup anything. You are simply using the IBM computer - just like "Bill's" computer. Late last night I had to quit as my neurons were rebelling and my head hurt. At this pint we will reformat the disks and start looking for another possible Linux. 7. In Summary: The linux developers have lost their way in the middle of the nigh and got a computer confused with -ba ba bh bh - bs etc. The cost of installation and ownership is through the roof with a high physical effort to do simple stuff. almaLinux is the same stinking pile as RH 8 but with a different name. Even at no cost it's still too expensive and unproductive to use in a business. - every mouse click costs. We are using SL 6.9 and SL 7.6 because there is no alternative for us so far. 7.9 is broken so never upgrade to it your internet goes away. The minuans at IBM have spent 10 years and millions destroying a very reliable, functional OS. This may be the last of Linux. It is no more fun - just another pain in the posterior. So out all the smoke the only OS that was even comes close to being acceptable is MINT. Don't like their desktop either but at least you can find things and it worked - we beat on it for a month and it ran VMware, and VariCAD, and others with out a problem. It also has the bad code in the remove program that can wipe you disk. Not good for a server. My though in the middle of the night was "Please God have someone fork SL 6.5" This may be my last post as we are running out of time. Thank you for your help in the past. I will miss you all.

Re: FWIW: AlmaLinux now available.
There is one ray of hope in this. AlmaLinux said it was going to support VMware. A crude way to do things but I need to support a lot of old SW from the last 22 years and older. My scheme has been to load necessary OS's under VMWare. Since disk space is cheep. I can and have loaded older OS's and run the OS that support an application I need to support. Still in an evaluation of new OS. PCLinux has a intersting install twist. It writes to the NVM - shadow and you are done trying to load anything else. Keyboard is disconnected, flash drive causes the system to power off. A real pain in the posterior. The solution is to relaod the Biaos to MB factory status or toss the mother board and disks it corrupts. If you don't know what you are doing - don't ever install it. Mint is in testing but the Cinnamon desktop is loused up. The Icons are placed automatically. So you have to stare at it for and hunt for what you need. A pile of trash. On the positive side it does support VMware and DiCad, VariCAD, AutoCad and our spice simulator. There is a hidden trap in Mint and it has to do with removing a package. If you remove it twice it reverts to a "rm -rf /* - nice cleanup by some C++ novice. It compiles - ship it. We have DEVUAN loaded and it works pretty well but unfortunately we were not able to install VMware or any Cad tools. I has some goofy path problems. The good news is that it is stable, and easy to use and above all doesn't have systemd. A real pluss +. When you look up install error messages it the same as Debian in 2017. So it looks like they have not addressed known problems. Too bad as I really like it. Two AlmaLinux problems is gnome desktop and a million clicks to anything and the systemD. I use gnome onf SL6.5 and it works very well and then it got DUMB as in stupid. The fact that they are going to support it for 10 yeas is a big plus. Being and IBM derivative - can they pull the plug anytime they want to and leave us high and dry again. IBM had a dismal track record of selling an OS and then ditching it. The small developers take a bath again. Next is MXlinux to she what it has to offer, Offers sysemV and a number of desktops - Has a large number of downloads. My real beef with the linux developers is that they are trying to make it like Windows 10 - every time it am forced to use 10 my head aches as my neurons rebel. The moron aware stuff is nuts, as the developers are now moron aware and headed to idiot level. The Linux supporters need to support one OS and keep it professional and UNIX like. Let the others use their cell phones. My three cents worth Larry Linder On Mon, 2021-04-05 at 11:09 -0400, Lamar Owen wrote: > On 4/4/21 8:39 PM, ~Stack~ wrote: > > ... > > Am I alone?

In search for SL 6.5 replacement - mint evaluation
Evaluation criteria. Cost of getting a task done X $ / hr. & $ / keystroke Summary: Cent8 we spent about 40 hr working on this and basically got no where. Score: cost infinity. RH 8 took so much fooling around to get a sample we gave up. Score: cost not defined, never tried it due to complexity of requirements to download. Mint 20.1 wee have spent about 40 hr. We could load it and it worked. There were a number of ugly parts to this. 1. It created a extanded fat partition to load the OS, this a 250G SSD This is serious problem when you load a bunch of applications and they are in /opt and /usr/local etc. 2. The real killer is the absence of /root. The fist login during installation is "whoever", there is no option for "usid" or a home directory that is other then /home/whever and userID = 1000. We set up users on /engr/users/whoever with a consistent user ID across all systems. It get started crooked and may not be fixable. userID is my choice and not sysemd's. 3. Passwd and shadowpw, group and shadowgrp are a front - it apears systemd keeps another set of files that it uses. It looks OK but these are ignored. Fixing things may be almost impossible. 4. Serious Security flaw. When you add "ftp" and "ssh" to system, on the next boot all the users displayed on the screen have gone away. Over night it somehow synced up with our server and added a bunch of closed accounts from the server - If you can get access to a network and attch Mint box it will create the users that exist on the server even the ones that are set to mode 000. These are Complete with account name and userID. ! 5. Last but not least: I wanted to install KiCad using the SW manager. It worked, crated the icon and put the files in /usr/bin/1001/bla/bla/bla. So I can install a program. A typical system in our shop may have 12 logins from engineer, software engineer, manufacturing, purchasing etc and the list goes on. So each has to load a copy of the program. Remember owner, groups, userID doesn't work properly. you can inspect the passwd and group, and they look good. Run pwconv and grpconv to update shadows, run the check programs it looks good, it still doesn't work. I have not stumbled on a way to set it up so it works. 6. We downloade VMware 16, it install and worked. Thank You VMware. We are going to buy it. 7. Now the real insidous part: I used the sw manager to remove the KiCad and it worked. Ten minutes later I became root and tried to install it again. It worked but the install was the same place as before. I then removed it and went for another cafeene fix. It was still removing files. What it was doing was doing was running rm -rf * from / as root. All there disks about 1.5 T of file were gone. Nice programming botch. It tells you a lot lot about the lack of testing that has gone into these systems. Just think if you did this on cloud setup result, a clear blue sky. Fortunately we have several back ups. score: $4000 / 2 programs - 0 working system Not a costly as Cent8 and non available RH. Trashed DVD and removed. Conclusion: Systems using systemd are not able to be set up to do what we need done. You basically have swaped "Bill" computer for "IBM's" computer. You can't set /opt and /usr/local/bin to other disks. We don't use LVM. I can only imagine the cost of running our 50 systems. We chucked Cent8, and Mint 20.1 DVD's, and reformated Flash drives. Next: Devian - a fork in Debian with out systemd is next. Std UNIX flavor and then we will try BSD. If you look at Linux over the last 20 years it has gone no place. things are still broken. Contributors have spent time working on eye candy, hiding functionality and trying to make it like Windows 10 - another convoluted disaster. It is "moron aware" sw. If Linux had any leadership group or company it could have been by now a world class OS. the 20 years have been wasted, Windows 10 would never have happened, you wouldn't have a zillion distrobutions that have the same flaws. SystemD is a pleague that will kill linux. IBM will abandon the users just as it did with the development of OS/2 and what MS did with windows 3.0. Don't trust them. My Boss's words. Each keystroke or mouse click costs $, If you measure the time it takes to find and run a task the new scheme is many times more expensive than running an app with a 4 char. name. Sill in search of 6.5 replacement Larry Linder
In search of a SL 6.5 replacemant
This may be my final comments. I tried to get a copy of RHEL 8.2 and it was a convuleted path. After all the BS and the not a robot crap. I just was not going to waste any more time one it. Red Hat RHEL is basically dead. I down loaded a copy of Linux Mint. After a lot of fooling around I manged to get it to run but it will not execute anything. Another "nugatory contrivance". I had a feeling I was in for a lot of work. To set up the network in manual ip I could put in box address,mask was defaulted to "24", route was easy. It took me a lot of imagine that the 24 was the number of bits. However I need to be able to set mask to 255.255.0.0 so we can talk to machine tools and my bitscope with something other than a browser. As with all the other systemd crap "root" was gone. I simply invented a root person. Then the fun began. I set up accounts to look just like we have on other SL 6.6 systems. When you set up a user you can set up user id the same as other account, use a different home location, etc. Once this is done nothing worked. I reviewed the /etc/passwd and /etc/group and there were numerous error - thing different than what I set up. Once I fixed this it looked good but didn't help much. I suspect that systemd keeps another set of files some where and just ignores the PW shadow passwd, and group. To run a small engineering shop we have 25 computers running around the shop all talking to the server SL 6.5. There is a complete back up of all boxes to a disk in the server and a synology box twice a day. For doing the grunt work there is about 135 .csh files that are run by "cron" in the middle of the night. For example we get an order for a system, parts we manufacture. Its entered into a file. During the night scrips look at parts lists, checks inventory and build a "partsToBuy" for purchasing. We cam also take a drawing of pc card layout and generate the CNC control program to make parts. The dirty work being done by computer in the wee hours. In mint and systemD none of this works. You simply cannot execute a script. Sure you can manually find it and execute it from "screen". Who ever mangled Linus has never worked in an engineering company or a manufacturing facility. It's just like the new path statement - has numerous references to Games. Mint is OK for a single user but it not usable in and engineering / technical/manufacturing/scientific operation. Conclusing: I could be wrong but when linux is systemd'd it becomes worthless as a general purpose UNIX like computer. My gold standard for functional sysems are Windows 2000 Professional, SL 5.11 with 3.4 Kde. In comparison the new linux stuff is just a pile of manure - no BS. Next on our list is devian that does not have systemd. and finally BSD 4.3. I have use BSD for 30 years. I first experince withe UNIX was in 1979 one Sunday afternoon. Was at my brothers house and he worked for AT, in a few minutes he loged in, uploaded the time card data for his group, ordered a host of material, ordered a telephone exchange to be build 3 years later - it took about 1/2 hr @ 300 baud. My second experiance was a Convex Super Computer that run BSD 4.1. It has 64 68040 processors running in parallel, 5 disk controllers and 5 disks striped as raid 5 all running in parallel. My self and 20 electrical, mechanical, and software engineers built a full aircraft, engine, engine control model for the A320 and CFM engines. A make file controlled the build. You just specified the aircraft, engine model, engine control sw version hit return and it built a complete model suite for you in about 3 minutes. I was built in C - anything at the time other than Fortran 66 was like passing gas in church. We could link up C control, Fortran engine models, ada maninence model and it all worked. The reason I am telling you about this is that Linux has been hy-jacked by a bunch of kids that have not build anything real. They specialize in eye candy and have gotten a real computer confused with a cell phone running at the idiot level. Proof - My 3 year old grand son can call grandma. When we finish the rest of the evaluations I will send you a set of notes as to what works and what doesn't. My first SL was 4.5. I would like to thank all of the SL members for their sound advice and solutions to problems that work. The internet is full of noise. I would hope that the labs start a new Linux based on a real linux or UNIX. Remember my GOLD standards Windows 2000 professional, and SL 5.11 with kde 3.4 a working computer with no BS. What am I dong here a Sunday afternoon anyway. Working on MINT - another lump of COAL. Thank You All Larry Linder
Rhel 8
After evaluating Cent 8 for a few months - The bottom line is that we could not run our linux based cad programs and it did not have the C shell that a lot of our utilities were written in. We decided to can it. Computer words - low level format the disk. So why would I even consider downloading a free RHEL 8 that is more of the same rubish. ? different label. Face it RH laid a big Egg and it is very evident that the management never tried to use it and evaluate it or it would never have been released. We upgraded our SL 7.6 to SL 7.9 and our internet connection died. You unplug the cable and plug it back in and you see the two lights flicker for a second and they are turned OFF. The connection icon says its ON. but it is not. Back dated our systems to SL 7.6. RH also changed EthO to more jiberish that is difficult to remember. So effectively SL 7.6 is the end of the road. We are evaluating Debian at the moment Since it is a RH derivative we shall see. Appreciate the communications - both good and bad. Sometimes I like to toss a rock into the pond and observe the ripples. My only wish is that the SL community start a New Linux based on SL 6.9 and erase all the needless junk added to SL 7.5. Mainly dump the systemctl crap. If only expands the number of characters I need to type to get it done and contributes nothing to operational efficiency - more bloat ware. I use VariCad 2D and 3D for drawing to run our 3D printer and CNC desktop mill to make real parts. The new version of VariCAD has a Clib problem and can't find 12 and 17. The real sad part of it is that the Clib 23 does not contain all the previous lib versions. So we had to forgo our latest update we paid for and can't use. Makes one want to sign up for Windows 10 another prize piece of work. :=( With RH effectively out of the picture we can not expect developers to invest in and support Linux applications with out a prime time OS supporter for stability. The labs provided the long term stability. So that leaves the Mac, Win 10, and maybe BSD which is under the hood of a Mac. A dark day in the OS world. Larry Linder
Problem with SL 7.9 upgrade
Upgraded one of our boxes from 7.6 to 7.9 and no network connections. Looked at Ethernet connection and no lights. Unpluged the cable and plugged it back in and you could see lights and then they went off. After tripple checking everything I could think of we rebooted to 7.6 and presto it all worked. Something in 7.9 turns off the Ethernet port or the driver in 7.9 is hokey. Anybody seen this before and can point me in the correct direction. The more I am forced to use the systemctl - garbage my dislike is changing to hate. systemctl status - forgot what it's now called. Someone must like to type - bla bla bla to do something simple. Our plan to upgrade all system to 7.9 is now on hold. Thank You Larry Linder
Re: Rocky Linux
We have seen this before and the good intentions fall by the way side when $$ enter the picture and personal lives change. Maintaining something is a lot of hard long hours. This is exactly why we have Fedora - in my opinion a bad decision on RH's part. A good way to get free testing and volunteer help. If you asked a question or suggested a different way to look at things - the kids at Fedora - shot the messenger. I would never consider using a volunteer OS for operation of a real world money making endever. Nice to play with but most are short lived and longterm support is non existent. They also don't take constructive critisim well. my two cents worth. Larry Linder On Thu, 2020-12-10 at 16:58 +, Teh, Kenneth M. wrote: > I agree with Vinicius.

Dose any of this surprize you.
In the early days of Windows 3.0 and OS/2. Windows 3.0 was short lived because every user knew it was a dog. OS/2 was pretty nice but had a fatel flaw as it only had one exit que. i a program dies and not gracefully it was rebo0t time. This is trivia trash but reflects on the Corporate Character of the perpetrators. RH 8 and Cent 8 should die quickly. The community with the support of a stable university should restart SL. Everytime I am forced to use Windows 10 my neurons rebel at the moron aware SW. If the linux community took a stable set of Linux and made 25 functional improvement a year and I don't mean rearanging the fruniture or new eye candy. Most of our computing OS nightmares would go away. As an example I just opted to get a new version of VariCAD and during installation it requested two different libc.SO's and a new C++ compiler. Tor rebuild the libc.so for 2.15 took almost 20 minutes it worked. I froze at rebuilding the C++ lib after looking at it. One thing I learned from the people at "stackOverflow" was that 2.15 did not contain all of 2.10 or 2.11 or 2.12. etc. The latest is 2.34. The tangled web of good intentions is killing Linux. Without the stability of RH most developers will flounder and sink. As the supporters of GNU retire and die off - the new generation has no desire to stay the course. Without the long term stability the applicaions / CAD developers will abandon it too. The bright side is that there is no automatic self destruct mechanism in Linux so even when the official support is ended we can still user what we have but not be able to upgrade our applications. We are a commercial user since SL 4. As a for profit organization the cost of just dumping 50 systems and install new OS's and applications is beyond our budget. A few new machines are introduced each year to support engineering / development. Most are used in the shop / factory as you would use a dish washer - just an appliance. The primary goal is stability. So the sword had many sharp edges. My 2 Cents worth Larry Linder
Retiring SL 6.10
In the commercial world we have to support our customers for 20 + years. If you want to stay in business. Machines are typically run to wear out. We install VMWare and load the OS's we need under it. Dos to windows 10 and several Linux systems. The only thing we use of the host OS is the file system and its security. We avoid the DUMB convoluted desk tops and use what is necessary to support our customers. With processor power ever increasing and disk space headed to penneys / giga byte. It a way to insulate your self from some terrible mistakes by well meaning people who make decisions on eye candy alone and have obviously never used or managed systems. An example is to count mouse click and key strokes to get thing done. Anyone heard of motion related injuries? We do not plan to re-evaluate RH 8 or Cent 8. Our conclusion is they are not acceptable for plant wide use. A sad end to a good product. Continuing to evaluate linux versions as possible OS's to jump to. The only one we have see so far is the chineese linux - it works wonderful and the desk top is direct and to the point. However we cannot use an imported OS due to some of our business being military related. The solution for people who need Fortran or other out of date compilers / debuggers - Load a current OS, install VMWare, load the OS you need under VMware, and use it. Our subscription to VMWare workstation is 168 $ . You don't need it for everyone but its a good solution for others. Another + is you avoid the obsolete lib errors. You avoid the goofy Gnome desk top as you can set up your box to boot and run VMware and all you do is point and click on the OS you need to run. All your data and disk files reside on the hosts file system so system back up is still used. That is what we do to ovoid * - 8 OS's. As long as they don't louse up the file system this is a good way to work. My two cents worth. Larry Linder
SL 6
I would be interested in a contribution to help support this effort. We have a number of SL 6.9 boxes, we would stay there for a while as all of our cad tools work. There are some things it doesn't have but we have never noticed them because they are not useful in the the day to day running of a Business. There are a number of SL 7.6 systems in lab but they are used for special tasks that require more modern libs. Such as the TI SW development tools. Its interesting that VariCAD installs and runs on these systems and they do not need special versions of lib to run. Do they know something other developers don't. Maybe. We support special machine we manufactured over the last 25 years. How we do this is to have VMWare and run the OS's back to the dos days and compilers and design tools we used then. When you use these systems it what they can do. Ever try windows 2000 professional on a really fast system. In 20 years we have been digging our OS hole deeper and deeper and accomplishing less and less. The evaluation criteria must change, it should be faster and do things simply - just new is a defect in judgement. We evaluated Cent 8 and got no where. It would not run our 25 year collection of scripts, or any of our new cad tools. In fact nothing would run. Basically useless pile of code. Another IBM blunder. All they can talk about is packages, packages, packages and nothing useful. We counted the number of mouse click to do a simple jobs and it was alarming. People can have repedative motion injuries. This has a serous impact on our workers Comp bill. Maybe RH 9 will junk the desk top and move on to something a person can use. The other bitch is the basic redesign of the UNIX file system and start / stop functions. The system-bla bla bla stuff is hard to remember and takes too much time to look up every time something needs to be restarted. The ICON Cheese was pretty good - I though is was add for Wetconsone orr ??? - The logic escaped me. If you are using it as an electronic typwriter and spread sheet it works but if you need to do anything creative it just stands in your way. Widnow 10 is moron aware and causes my neurons to rebel and RH is moving in that direction. At some point the Industrial / Scientific OS must diverge for the telephone mentally. New linux version are being continually evaluated and most last 10 minutes into evaluation before me give them a thumbs down, some are cute but eyecandy does not make it when you need to get things done. Larry Linder
Re: SL6 firefox upgrade.
After a installation of Cent8 we could not run our cad SW and a lot of other applications that ran fine under 6 & 7. We reformatted the disk and put box back into service as SL 6.9. Have been evaluating other Linux Unix systems replace our SL 5.11, 6.9, 7.6 systems. Genome desktop is trash. If you consider the number of mouse click it takes to do anything - it one of the big time wasters and a candadate for repetative motion complaints. I would never recommend RH 8 or it derivitives. Try the chinese desk top and you will see how smooth and easy it is to get thing done. 15 years ago I gave up on Fedora as if you had a complaint or constructive criticism - The kids shot the messanger. And that is how crap happens.

After 6.10 update - SAMBA - broken
We liked how samba allow us to connect all systems. Now even the Win 8 and 10 machines do not see any of the other systems. They all see the other win machines but none of the linux machines. On systems that are running VMWare the win machines can see VM. I also found out that a number of BeagleBone Black on the network were running smb and were visible. Last Saturday for an hr or so the smb network was running and I could access everything. I resarted smb on the server and it all went away. I shut down all the devices on the network except for 1 Win 8 box and 1 SL 6.10 box. Nothing. I looked on the internet and read every alticle I could find about problem and ran at least 50 different "fixes" and nothing. The hardware and systems are good as I can SSH into any computer on network. There are options in the smb.conf file that do not appear to do anything the SMB.ORG documentation said they did. The documentation is not good as it seldome says what the default setting are. It sort of like being blind in an empty room. testparm and smbclient -L - everything looks OK. I got ran pdbedit with a number of different option and did not see anything different between 4 systems. The fire wall has the right permissions and the correct ports. I even shut them down. no differences. The numerous log files in /var/log/samba did not reveal anything use full. It was quite a history and goes back to 2012 to present. No new log files in the last 10 days. There are several rants about the developers of samba lousing it up, with the security additions. After a number additions to a development copy of smb.conf and a lot of changes its almost like wen you restart smb, nmb, and winbind it is ignoring the smb.conf. Defining users in square brackets works so it is definatly reading the smb.conf and just doesn't pay any attention to most. This is sort of redundant, but necessary to say. Is there any way to look at the network and really see what is going on? Larry Linder
Re: [SCIENTIFIC-LINUX-USERS] scientific.org
Thank You for the expert analysis of the problem. One of the problems with searching the net is that most of time there is advice that is correct but out of date or wrong OS etc. and they are not clearly labeled. We have downloaded the most current copy of Sama-* and all boxes are up to date. I will remove the statement form the smb.conf. When we tested it there was no differences on the network picture. WE took down the fire wall on all boxes and after a reboot it made no difference. In the Firewall The samba box was checked and the required ports were enabled. We have one system still running SL 5.10 because it has a "mongrel" set of libs so we can run spice, a filter design program and other applications. It uses VMware and we have a lot of olders OS to allow us to support projects that are 0ver 20 years old. It uses samba to communicate from the old windows OS to the SL 5.10. This has worked well for a long time. What on the network controls the samba server vers a samba client. The documentation on this is sparse.

Re: Scientific Linux 6 status after November 2020
I see the post on Sl's web site for Nov. 20 as end of life. I don't know where we picked up the date of 2024. Our plan to use SL 6.10 looks like it has to be changed and we move on to SL 7. Is there an easy way to update server from 6.10 to 7.6 or latest version of 7. We have 7.6 running on several boxes and it has been stable. It may also solve our netowrk problem unless security update was applied to SL 7 also.

Re: [SCIENTIFIC-LINUX-USERS] scientific.org
What we did. We commisioned a number of new boxes to Sl 6.10. We also updated our server over the weekend. When we found out the server could not see other boxes on our network. We used yum to upgrade sama and smbserver and that did not fix problem. When I did a search on the internet for the problem. There were a number of reports from other distributions of linux 6.10 with the same problem. I tried their recommended fix but did not work. They added aline into smb.conf. client max protocol = NT1 They also indicated that windows 10 had an issue with samba. Several of our laptops running a stripped Windows 10 can see the server but not now. My problem goes deeper than just samba. On sel 6.8 server we were able to see all of the workgroops and all of the Linux boxes running 6.8 and 7.6 and able to connect. Now the server only sees its self and no windows "workgroup" systems. Our UPS shipping box used to show up on the server and other linux boxes but no more. ssh and scp all work and recognize each other. Our decision just to update SL to 6.10 was due to a group decision. Collectively they did not like the sl 7.6 desktop and a number of needles changes that did not improve their ability to work. We tried Cent 8.0 on a test box and it was a worthless - a video game but nothing worked behind it. We looked at the end of life for sl 6 as 2024 and thought it gave us a lot of time to find another linux or BSD that we could use. The problem with the developers is that they never use it, run an engineering shop and small factory that generates a good revenue stream. They move the frunature around and change the "eye candy" but basically do not fix operability issues and connectivity. Marketing is busy selling a Cloud applications and databases driven by a quadraplegic desktop. You move the problem from a local server to the great server in the sky "Cloud". Wooppee. In years past I had a Convex 64 bit system running BSD 4.2 and I could link C, Fortran, ADA and other applications without a problem. It had an incredible rev control package that allows users to check out files or view or edit or make various simulations. One gate keeper was required to run it. It had 64 parocessors running in parallel and 5 disk controller in parallel driving a large Raid 5 disk array. It ran flawlessly for many years. We kept it in lock step with a SUN server a 1000 miles away without a problem. In a few years the powers to be thought it too expensive compared to a flock of IBM desktops that could do nothing but word smithing. When they made their decision - I just packed up my desk drawer, removed my name tag from the office wall and wished them well.

sl 6.10 server no longer sees other computers on network
Oops: I updated server to 6.10 and tried to add vcn and now server will no longer see any other computers on network. I used to see all linux boxes and "Workgroup" but now it simply sees itself as an icon but it goes nowhere. All services are running, so I manged cross thread it. Mad two mistakes by changing things after update to 6.10 before testing. ssh is running as backups are good, I can ssh to any computer. Any guesses as to what when wrong.
Re: Mate for CentOS 8
That is precisely why we gave Cent 8 a pass. Nosencical desk top and it inability to run a number of Engineering application. I ran Libre office fine but nothing else. So unless you are a word smith it basically useless. We are going to upgrade servers to 6.9 and a workstations to 7.6 and hold our breath for the next 4 years. So far we have evaluated a lot of Linux varients and most were pretty bad. Nice to tinker with but basically not industrial. They show that the developers have never worked in industry or had to bild and maintain a large number of assemblies. Our current leap back is to BSD !!! And that falls into the category of desperated measures by deperet men. Every time I look around a couple of Windows laptops we leave on line are constantly being upgraded and the upgrade fails and THEN ??? Given the mixed state of Linux and DUMB desktops and infinite mouse clicks to do simple stuff. Industrial development will continue to be Windows only. The Linux community is constantly shooting themselves in the foot and sometimes higher. Red hat was a good stable platform prior to 7 and then the kids took over and you have a video game. Not good. Where do we go from here? So the world will migrate to a Chinese tablet or telephone and computers for industrial and engineering will disappear. If you look at the slippery slope we will slip back into the dark ages of DOS and Assembly. There will not be enough of market for engineering and scientific computers to make the high volume low cost possible. So much for negative stuff. A university group or government lab in the US should offer a New SL and maintain it. The gate keeper should keep it in US English. And please no more cheese Icons.

Revisiting Cent 8
Thank You All. We looked at what did not work and decided that there was something really wrong with the Cent 8 install we had. The final clue was that we could not run multiple terminal windows so you could not look at several things at once. nmcli could not find files and just died. We were never able to change IP. We could not execute any application other than LibreOffice. There is something basically loused up the installation of Cent 8 and we could not find it. Solution: We did a low level format on the disk Cent 8 was on. Just too much time spent to get nowhere. Last night we installed PC Linux and in a 1/2 hr it was up and running. Have not tried applications yet. Correct IP multiple terminals, other boxes see it. Most of our boxes and server run SL 6.9 and 7.6 so we have a few years. The experience did a lot for us as to not consider RH for a purchase. My only concern is that there is fork in the road. Hand held devices for the mass users and the right fork in the road is now partially closed. The kids just can't get it right because they have never used a computer for anything else but "eye candy" and think its ok to use a million mouse clicks to do something simple. >From an engineering standpoint windows 10 is rubish, RH is following down the same path. So where do real engineers who need a stable platform turn to. It appears that RH has been IBM'd so it now useless too. SL should consider maintaining a SL linux for the sicentific / engineering community. My Last two cents worth Larry Linder .
Revisiting Cent 8
Boss asked us to take another look at Cent 8 because Cent 8 box in corner was using an IP address that is in middle of several machine tools. It had been running since oct 19 and we gave up on it at end of December as basically worthless. I looked at all the pages of directions on the internet and Cent pages for a way to change the IP to a range that is used for our boxes. When you run ifconfig -a you see the configuration and no eth0 or eth1 but you find enp3s0: First I found the configuration tools don't work. network-scrips is now empty. I used yu to install scripts. Edited eth0 to correct address and rebooted as "tool" didn't work. Something is very wrong. The manual pages from RH dont work, other published directions are as if written for system zzz. Cent help pages are useless as they cover Cent 7 and little of no Cent 8 real help. Anybody who has actually changed the IP to static sucessfully - please tell me how they did it. The boss looked at the bill for switching to another OS that is not a derivative of RedHat and maybe a Macks and he wanted us to really look at Cent 8 again. As a business it all the bottom line, there is nothing free. We have a considerable investment in SL from 4 to 7.6 and I would hate to think of the cost of just tossing it all. Is there an alternative desk top as Gnome as it is terrible, You can't have two terminals open at once at least on this system. The only thing that worked was LibreOffice. The rest is nonsensical. As you all can guess is that I am an engineer and not an IT person. Larry Linder
Re: Who Uses Scientific Linux, and How/Why?
We have used it since SL 4.1 As a small engineering manufacturing company we rely on its stability. As an old Unix guy it was easy. We have added a lot of packages to it for various Engineering projects and with Maria DB is runs our manufacturing operation. We have a few thousand scripts to do odd jobs at night. We use it as a server for our few Widows machines that cannot be trusted with critical stuff. Our file system is huge for a company as we have been shoveling project files and part libraries into it for 20 years. We have tried Cent 8 and it is a miserable example of cute but disfunctional desk top. It could not be connected to any of our other machines and the number of mouse clicks to do anything is horrible. Fedora was a mistake. Driven by people with no commercial experience. When the Boss is breathing down your neck and asking why the invoices didn't go out on time or worse yet is paychecks that are late Friday Noon and the guys in the shop are not very understanding. What we have been looking at is PC Linux because it still uses the traditional Unix boot scheme. To reorganize something that worded well with a supervisery bunch of code is nonsense. So it allows a server to boot a bit faster. We reboot our server once every 6 mo. It's down just enough to allow a cleaning and checking of fans / filters. So why bother. So my attitude is bqd but I can rest easy and not worry about a call in the middle of the night saying the server is down and we need it Monday @ 7 AM.

Centos 8 last straw
I replaced Centos 8 video driver with nvidia driver and now the left is left and right is right. So next sw upgrade this will probably go away as it did last sw update. You can't lauch more than one terminal window from the drop down. You have to launch a terminal window from the previous terminal window and low and behold you are back to your login and not the directory the 1st window location. We tried to run cups and it complains that the return was too fast for the systemctl to see. This is insane madness. Before we abandon Centos 8 is there another desktop that is rational?? I tried the BOXES and fundamentally got no where. The directions are ???. There are two things that work 1. OpenOffice - I can get files on server and edit them but because of some security problem can't save them. 2. Firefox does run and you can cruise the network but for some reason the downloaded files are in the correct location but zero length. So basically after a mounth of fooling around with centos 8 I have to declare it a nugetory contrivance. 1 more week and we have to reload SL 7.6 and give it up. Maybe we will try RH 9 in a few years. Larry Linder
Cent 8
used the utility yum to update test box and nvidea driver was replaced with something else. Now on duel screen set up left screen is not the right screen. You can set them up but the nomenclature is 180 deg.from what the nice splash screen says. I can do 3 axis coordinate conversion in my head but mix the backward mouse and left and rigth being reversed is something else. Doesn't anyone check there work !!! Maybe is it compiles without an error it good. Does anyone have the email for the squak page fo Cent 8 Check out the new Chinese desktop !!! and the rest of the desk tops are dead. We may be using SL 7.6 for a long time. Larry Linder
Re: centOS 8
Hope the SL conversation net will stay alive. I have found that there is little "noise" when you ask a question. Most of the stuff you find on the net about a subject is just nonsensical.

Re: centOS 8
After tossing in the towel last Thursday we decided to try the nvidea install and it worked. It is nice to have my dual high resulation displays back. Centos 8 problems. 1. We noticed that the mouse wheel has changed direction - why after 40 years. This should be removed. 2. We changed the mouse direction back to to what it had been for 40 years and now you can't copy some command lines from a tutorial we are looking at with the browser. 3. "bash" refuses to execute any command line code or linux executable file. 4. There does not appear to be a C Shell. We have 100's of usefull scripts that don't work. The man pages are there but no /bin/csh. 5. We were able to install NVidea drivers but it still didn't work. You have a couple of commands to run to set default to nvidea driver. This is the only thing that has worked. 6. When you drag a terminal to the desktop and click to select it. It rearranges all the other desktop terminal windows. 7. Focus follows the mouse was one of the most useful things when putting data into other documents or spreadsheets. Without it it makes doing my bank ledger almost impossible. 8. Simple things are now complicated and require 3 to 4 time more mousing around to accomplish a simple task. 9. After fixing the mouse direction we cannot even run "yum" Checked permissions and paths but bash can't find it. 10 The neat little GUI that allowed you to set up users, groups, specify UID, home directory and shell for users is gone too. It all back to the command line. 11The function to add a member to "group" doesn't work. It does not change the "group" file or maybe the group file has gone away too. 12"fstab is now jiberish and the man pages have not changes. I need to add a couple of directories the install disk partitions the insall did not install. 13after a lot of fooling around we were able to install one printer out of the 6. It could not find the printserver so our large format HP Plotter could not be installed. 14Libera office can now get to documents on the server, you can edit and change file name and save them. A great improvement. 15Setting up network and fixed IP's was a major major cammand line exercise. The old utility that made it easy is now gone. 16None of my CAD / CAM packages work! So there is nothing to plot. 17Last step is to reinstall SL 7.6 with KDE on text box and call it done. Thank You again SL troops for the great work. I hate to say this: The most productive system in the shop is SL 5.11 running KDE 3.4. It has 12 desktops, with VM-Ware it runs all our old Windows apps we need to support paying customers. Focus Follows mouse and you can edit and paste documents just by moving the mouse. It can capture sections for a windows cad package and you can paste the prawing into an Appache OpenOffice documtent and get you work done and get home for supper. Centos 8 is a major loss to the engineering community!!! RedHat & Centos has laid a big Egg. The product should be recalled as a defective product as its basically useless. I would advise anyone who is a unix / linux user to not even bother with installing it, If Red Hat were smart they would look at all the good stuff that has worked for years and make sure new OS included them and they would have a winner. They may not be fancy but they work. The thought process of its got to be "new" or is "dead" is defective though. You build on what works. I very apparent that the developers have never worked in industry and a very limited experience with doing useful work A note on Fedora 20 years ago I complained to the Fedora community about a problem in a version. The response from a "KID" not good. Basically shot the messenger. We turned FIDERA OFF. Now if Apple made the Mac OS available at a reasonable cost Window 10 and Linux would simply cese to exist. You always have to remind your self it take time it costs money. If it a good product the customer will be on your door step with cash in hand. If there are no customers things will go cold and dark and you will become hungry. Another weekend almost shot- I am going back to sleep.

centOS 8
Nothing should be this hard to configure and set up. 1. The install did not recognize two other disks on system. if you run "fs" you get a list of disks and a number of /tmp partitions. When you try to edit "fstab" it is non-sensical. Didn't try to run "mount" as the man pages are not what you see. 2. Video is basic VGA and it ignored my GForce dual monitor card. 3. Tried to install printers and didn't see "cups" even though I selected it to install. 4. I tried to run a couple of our linux cad packages and bash could not run the process. Permissions and ownership was Checked but no luck. 5. Even setting up the sytem name and UID to what we use on the other systems had to be manually. Graphic network didn't give you a clue. 6. When it shuts down you have to pound on the key-board and try every key and then after a long time it finally wakes up. Couldn't what key did it. Just don't have time to screw with it. After spending two days I gave up. This whole think looks like a very low level business workstation for the mentally challanged. Run my IBM computer the way I designed it or just go away. You can only run my programs you can download. Most look retarded such as "CHEESE" is there a connection between title and function - its a major stretch of the immagination. It wants you use a cloud for everything - we don't want to use the cloud for anything. Our internet provider sometimes takes a 1/2 hr nap during the day. Its very fast when it works. (Spectrum) - AT in our location was hopeless, bad service, bad price. For now we are going to upgrade all systems to SL 7.7 and then look for a linux that is usefull for real engineering, manufacturing and business. The labs should look at building there own. Any suggestions? I will go back to work and give up on centos 8. If I had purchased RedHat 8 I would be really ped for getting ripped off. Larry Linder
centOS 8 install crash
This really off topic but there REL error reporting does not work. It is not a centOS tool but RedHat. Saturday PM - first failure. At least we could reboot system. Sunday AM - second failure. System is dead and SL 6.9 must be reinstalled before Monday. Tried to install centOS 8 and it gets to point where I sets up disks in classical scheme, so as not to clobber users files, it asks for root pass word and it crashes. The crash is reproducible but the result Saturday was recoverable, Sunday's crash is not recoverable. I checked download for errors and it agrees with their check sums. Have been a SL user since 4.1 and never seen anything like this. I wish SL could continue as the centOS 8 is half baked. You can't send an error message to them !!! The Red Hat bug reporting tool goes no where. This is why we never used Fedora - you couldn't thrust it. We had planned to up date our business to centOS 8 but I think we will stick with SL 7.6 and update all system to that level and quit for a year. I would like to thank all the troops and contributors to SL for an outstanding work. If anyone know how to forward the error messages to centOS I will try a third time next weekend. Thank You Larry Linder MicroControls LLC
Re: SL6 end of life
We have some systems still running SL 5.11 and they work fine. No support but they continue to do their job so why update. When they are no longer functional then it time to change. Most systems we have have are on 6.9 and some new on 7.6. The only improvement would be to unravel the security stuff that we have turned off. The networking of all the boxes is not easy because of different SMB's We simply have a script in cron that suts off network after 5:20 PM and turns it back on at 7 AM. Prevents the chineese from the endless pinging of our network. Our archaic systems are on run under VMware 14 and they all run as intended. We just need to support some devices from the early 90. We will miss SL as we migrate to Centos. So far in 9 mo we have seen little progress in this development. RHEL 8 promises according to release notes a new and better networking scheme. It is interesting that there is a new "yum" as an RPM but do you need to install it to install the rest of the .rpm packages on the RHEL 8. RPM pile. This looks like the chicken / egg problem or can you install the RHEL rpms with the old yum? I have to admit that I did not read the fine print. And how about a empty new system? We are going to build a new box to try it soon but are dragging our feet waiting for CentOS 8.

RE Future:
Cannot read crystal ball as it is just a cloud at the moment. As an industrial users RH has be a point of stability in the Linux world. I don't need the latest SW I just need it to be consistent and reliable. Several of our servers have run several years between shut downs due to periodic maint. As a SL user from SL 4 to SL7.6 I have a lot invested in our systems - we are not funded by any Gov. and it all comes out of our pocket. We have invested in a number of cad packages for Linux and they mostly run on RH 5, 6 , 7. We have to support projects that are 20 years of more old. We do this with VMware on our SL 6.9 server and clients. We can run DOS to Windows 10, Mac stuff and keep our unix file system in an organized manner. Projects stated in 1992 - current. I started out with BSD 4.2 on a Convex super computer supporting 30 some users running simulations of aircraft and jet engine control. We used this as tool for FAA Certification to make sure the imbedded SW and the engineering design intent were consistent and dynamically tracked. This was 1985. As a private company we need the stability and consistency of a commercial product supported by a Gov agency for long term stability. Will we stay with CentOS is a big ? and looking at the Windows 10 moron aware SW and the illogical file system. Without SL we will have to make the decision in a year or so. Immediate plan is to update all 6.x machines, and 7.x machines to latest version and wait. Can't afford to be on the bleeding edge. I am going back to work - One more pain the posterior.

Re: Planning for hypothetical RHEL/CentOS cancellation
The library and dll files are still are a problem. However, I just purchased VariCad a 3D modeling packange and it install on a number of differenet systems without a hitch. They just incorpoarted libs into the package. A complete contrast was the software development package from TI. It complained about lib differences and finally was installable using SL 7.6. Using KDE desk top there is an error in KDE that when you clicked on a information box to change a directory it just died. You could restart the app and it got to the same place and died - no error message, it just packed up and died. You had to go back to the video drivers and change a config file and then it worked. I would hate to say how many $$ we have in this. If it were not for a couple of good guys at TI who took and interest in prolem we would never have gotten it to work. Eagle for Linux has the same lib problems. We did not purchase Eagle because the current owners are more concerned with Icon develpment than install, performance and functionality. Literally no significant progress in almost 15 years. The list goes on - When will developers learn, this crap has been going on for 30 years and we are not getting smarter. VariCAD was a breath of fresh air. Get a 30 trial and buy it as it reads and writes ACAD, SolidWorks, Igis, and more. For $600 it was a bargin. This is not a VariCAD add but an example how smart developers do things. A contrast.

Application Server for Linux
I am interested in an application server for out company. We currently have a SL Linux server running with "Samba" and all boxes some with Windows 7 with upgrade and others with VMware 14 running on SL 6.9 and SL 7.5 all talk to each other. I have a number of linux applications that I have on the server and would like to make available to all other linux boxes some SL 6.9 and SL 7.5. Currently we just use a local install on the SL boxes. Any recomendations or things I should stay away from. Larry Linder MicroControls LLC
Re: After Install last physical disk is not mounted on reboot
When you look at the /dev/disk and the directories there is no occurance of "sde" We tried to modify "fstab" manuall but the device code - decoding scheme didn't work. System booted to "rescue". There are a number of problems with the GigaBit MB and one has to do with the serial communication. I looked into the bios and all 4 WD disks are present. Disk 5 as "sde" is not seen there. We tried moving disks around and the same result so its not a disk problem. These are all WD disks However we have noticed that when you count up the devices to be mounted in "fstab" there are 16. A number of the mounts are due to the user and SL OS. On this server we will stick with xt4 for the time being. We have investigated a Port Expansion board to allow us to use more physical disks but when you peek under the covers and look how they work the performance penality is not worth the trouble.

After Install last physical disk is not mounted on reboot
The problem is not associated with the file system. We have a newer system with SL 7.5 and xfs and we have the same problem. I omited a lot of directories because of time and importance. fstab is what is mounted and used by OS. The fstab was copied exactly as SL 7.5 built it. It does not give you a clue as to what the directories are and it shouldn't. The point is that I would like to use more pysical drives on this system but because of MB or OS the last physical disk is not seen, which is "sde". One of older SCSI sysems had 31 disks attached to it. The Bios does sees 1 SSD, 4 WesternDigital drives and 1 dvd. SSD sda WD sdb WD sdc WD sdd WD sde is missing from "fstab" and not mounted. plextor dvd We tried a nanual mount and it works but when you reboot it is gone becasuse it not in "fstab". Why so many disks: Two of these disks are used for back up of users on the server. Twice a day @ 12:30 and at 0:30 each day. These are also in sync with two disks that are at another physical location. Using "rsync" you have to be carefull or it can be an eternal garbage colledtor. This is off topic. A disk has a finite life so every 6 mo. We rotate in a new disk and toss the oldest one. It takes two and 1/2 years to cycle threw the pack. This scheme has worked for us for the last 20 years. We have never had a server die on us. We have used Sl Linux form version 4 to current and before that RH 7->9 and BSD 4.3. We really do not have a performance problem even on long 3d renderings- The slowest thing in the room is the speed one can type or point. Models, simulations, drawings are done before you can reach for your cup.

After Install last physical disk is not mounted on reboot
New System: Gigabyte Mother board. 32 G Ram 6 core AMD processor. ext4 FS ?? Disk: 0. SSD 240G sda cibtaubs o/s 1. WD 2 TBsdb contains /usr/local & /engr, /engr/users 2. WD 2 TBsdc contains /mariadb, & company library 3. WD 2 TBsdd contains /backup for other machines 4. WD 2 TBsde contains ... 5. Plextor DVD Mother board has 6 ports. These are physical disks setup during install, using a manual install. After install is complete, system reboots, everything works but there is no sde present in fstab and it is not mounted. According to RH website we are not exceeding any published limits. There is nothing abut this problem with GigaBye MB. This system does not use logical anything or any raid? Any clues as to what is going on. Don't know how to decode disk definition in fstab? My discription is how I set it up.

Re: SL 6.10 upgrade & smb
We came to same conclusion as others advised us to do and loaded SL 7.5 onto a flash drive and updated one box. It was pretty impressive as to how the network stuff hooked up. The real driver in this is a TI CCS package that we needed for a new imbeded project and it required a more upto date libc. Thought about updating 6.10 but rebuilding everything fell into the too hard catedgory. We fixed the SAMBA problem and the out of date libc by the upgrade to SL 7.5. We liked the KDE desktop as in my case I have two large monitors and 12 desktops open. A form of insanity mey be but a very effective way to design and build stuff. So we can continue to run old SW we have been using VMWare sine version 6 and now up to date 14. The VMWare has everything from DOS to Windows 10. And it all just a click away. This way we were able to recycle old systems that we kept to run old stuff.

SL 6.10 upgrade & smb
We upgraded one system to SL6.10 and noticed that it no longer was recognized by the serer and it could not see server or any of the other linux or windos boxes. We verified that they network is defined as WORKGROUP on all systems. We looked at smb.conf and the firewall and nothing makes any sense, It is set up like all the other systems. Is there anyway to un update a system say from the 6.10 back to 6.9 ? other than reloading it. We also noticed that Nautilis was been "carved on" and a lot of the nice features are gone. smb builds it own host table. What creates it. It is just a simpler version of the "hosts" file we on all systems. Thank You Larry Linder MicroControls LLC

Loading SL 7.5 from Flash Drive
I have a usb 3 - 16 G flash drive. When I try to drag and drop "SL 7.5 everything" it gets to 4.2 G and quits. After about 1 minute it come back and says that it cannot splice file. The crual joke is that when you move the partial file to trash - no delte option is available. It creates a .Trash folder. Two tries and you dont have enough space. Nice idea but DUMB. Oper a terminal mode and us "rm -rf *" and you are back in business. I there any way around the 4 G limit and where does it come from ? Thank You Larry Linder
Flash Install of SL 7.5
I have been asleep for a wile. Most of our systems are 6.8 or 6.9. Have a new box in pieces ready to put together as a demo. Would like to use a flash drive to install 7.5. A few months ago I noticed a letter about a problem with doing this. ? does it work or not ?. Really dislike the dual layer as I have a problem with writing tool that says it does't support dual layer disks. Have a bunch of 16 G flash drives and it would be a good thing to able to use one for install purposes. Thank You Larry Linder
Cad Package Move from 5.11 to 6.0 done and working.
Thank you all for your help. Once we knew that the Cad Package required 32 bit libs. and where it was looking for them. It was pretty straight forward. We use a rater agricuratural approach. We "scp" required libs from old working machine to new system and put required 32 bit libs into /usr/lib it ran perferfectly. Had to go back and use orrigional licence key to enable all features. No problem there because we purchased it. For future ref. we made a data CD with allrequired libs and licence key. The name of the CAD package is Eagle version 5.11 we use to design and layout printed wiring boards. The only feature we could use is a way to build transmission lines with a set impedance and equal lengths. Whe we are building processor based devices / boards that run at a G Hz or above. The arival of all data and adresses at the processor is critical any skew in address or data will cause you a problem. Autodesk owners of ACad purchased Eagle and began by modfying / adding icons that are nonsensical. This is really bad for me becuse I am a dislexic (sp) where when you look at funny Icons they are giberish. Other than asking for a monthly subscription fee and having to login to their system to use the rented package, they have added nothing of value. A lot of times we are in an environment that does not have internet acessablity and need to look at a schematic and you can't with new login requirement. We have decided to pass on the Eagle upgrade becuse it offers nothing of value to us other than more incomprensable Icons. We are looking for another package for circuit card design. We paid 2,700 $ for Eagle Professional awhile ago and it really worked. We were willing to buy it again if it offered more design features that are hard to duplicate by hand such as constant impedance lines. The "Radio Amature hand book 17" has a good design layout and formulas for making transmission lines on a circuit board. Thank You All for your help and advice. Larry Linder
Re: Scientific Linux 5 End of Life
We are still using SL 5.10 on a number of workstations. The users are used to using KDE with a lot of desktops - 12 or more.

We have everything from Windows 2000 Server to Windows 10 on system. Thank you All for an excellent OS. Got a number of responses but there were a lot of missing parts we could not locate. Anybody really done it? If we could only have KDE for SL 6.

Installing KDE on SL 6.8
Apoligize for bad Subject. I am being forced for security reasons to migrate to 6.8 from 5.10. I use KDE a have 12 desktops set up so I can run a number of cad packages and numerous text adn spread sheets. When I loaded 6.8 on to test hard ware I can't run KDE or switch to KDE. I searced on web and found a lot of noise. Any help would be appreciated. Gnome just is not up the work load. You speen all your time mousing around. I have 12 desktops running with several cad packages, circuit designs, simulations, spice, Appachie OpenOffice, all running on different desktops. I need to switch between subjects quickly. Thank You Larry Linder MicroControls LLC

Re: Filesystem package messes with /usr/local
What we have done for the last 25 years on Unix and Linux systems to avoid this problem. On a separate disk we put /home, /usr/local, /opt to keep the OS install sysem from rewriting these directories. There is also a /co-lib disk that we keep all data sheets and parts info etc In a manufacturing environment this is real help. We add these to the users PATH and everything works out pretty well. They can easily find information and added sw. It it doesn't run correctly we then have get a new version a crude way of doing things but it works. Above all else run a couple of back ups and keep on offsite. Our insurance agent kept a back of system on a separate box. The theirves stold it all and the only thing that saved him was we had upgraded his system a week before and the old disks were still on the shelf. So without the orig. disks a cloud back up may not be a solution.

Install SL 6.7 on Gigabyte 970A-DS3 - No Ethernet port.
This is the same problem we experianced with SL 6.0 in August 13. ( Two years ago ). - the comm chip set is not broken. Run ifconfig and you can see that it Receives data but no transmit. SL 5.10 works. SL 6.0 and later versions have a mistake in driver and kernal, are broken.. We used a ELRepo kernal and driver to fix problem with SL 6.5. It has worked well for 2 years. We gave up on SL 7 ect. for a server / back up. We just purchased a raid box with 10 slots and it uses Linux with a wonderful clean and logical desk top. For other boxes in plant we decided drop back to SL 6.7 which works pretty well. But no Ethernet as in SL 6.5. Looking for an Elrepo driver and Kernel to fix problem. There is not a set for SL 6.7. Anyone have any idea when we might see the driver and kernel. When I am looking at complaints with with install problems the Ethernet problem may contribute to a lot of these unhappy campers. It is too bad the upstream vender did not fix the problem up front. It would have saved a lot of people a lot of fooling around. Leaving broken problems unfixed is a mistake and just conpounds the orrig. error. As the versions move along and the number of users expands things just get worse. Thank You Larry Linder
Re: SL 6.7 Fails to finish install and more.
Removed 5 th disk and tried a LVM install and it did not see disk 2, 3, 4 and you could not find if they were mounted or ? - nothing. Decided to go back to orig. hand lay out and when you get it done it says that sda must have a GPT disk Label. There are no provisions to do this and its not done automatically in any scheme we can find. The scheme the guys used months ago does not work of allowing it to create disk label and then bail out. Ounce you try to use the LVM there is no way to get back to square 1. This is really getting DUMB. Right next to this box is a another box with 6.2 loaded and using a manual partitioning scheme that has worked for us forever. We never tried to use LVM on this system. How do you not allow a user to install the system any way he may need it. The failure to allow the fifth disk to be installed is pretty bad. The last try will be an install with a new mother board and new disks and then we quit fooling around. My only complaint is that how do a bunch of kids take a nice operating system and totally louse it up.

Thank You I was sure that there has to be a common thread. There is another system available that has an identical hardware suite. We can unplug the disk pack and try it on another hardware set. Then we will know if we have a bad mother board. Larry Linder

The downloaded DVD was error checked before we began this exercise so we are certain that the DVD set is good. The 5th. disk was connected to different port on mother board and if we limit the number of disks to 4 + DVD drive it works and install completes. We are convinced the Hardware suite is VALID. The other output ports were vacated when removing a disk. This try we selected default on SL 6.7 to automatically set it up and use LVM to assign disk. It proceeded normally and when it gets to sde1 we get an error message that it cannot format disk. This disk will work as sdb sdc sdd. The walk back did not give a clue except that the second argument to function is null. or null string as in other tries. When in manual disk setup there at least it formats sde but will not mount it. Same walk back info but the error is now it cannot mount disk. Next we will try 5.11 on this hardware and see if it works. another test is to install BSD. Other people who use BSD report that they have mounted 99 devices with out a problem. This box is not connected to our network as it is used all day. Will connect it Saturday and see if we can file a bug report. Larry Linder
Re: SL 6.7 Fails to finish install
First step was to remove the 5th disk from the system. I was mounted as /sde1 After this is complete the install finished with out a problem. A long time ago we ran into this problem and it had to do with the number of devices. We used to run 32 SCSI drives on a server using two 16 device cards and when the high speed serial stuff came out we were suddenly limited to 6 devices. - This from memory. The 5 SATA drives + DVD as a SATA drive is 6 Mother board is labeled 0 -> 5 all ports are used. We unplugged cable from 5th disk and the install went normally. It accepts sda1 - sda12, sdb1, sdc1, sdd1 and the DVD drive in 5th slot.

SL 6.7 Fails to finish install
Dear Sir: We are building a new server and decided to use SL 6.7 The system is a quad core AMD with 32 G Ram and 5 T bytes of disk space. The OS is installed on the sda1 - 10 /engr is installed on sdb1 /mysql is install on sdc1 /backup01 is on sdd1 /backup02 is on sde1 The install progresses normally till it get to sde1 it appears to finish the format correctly and when it come time to mount the device we get the following: "An ERROR Occurred Mounting /dev/sde1 /backup02 mount failed (9,none) This is a fatal error and install cannot continue." Disk and cable have been swapped, Port has been swapped. Problem does not follow port or hardware. The first time it occurred Saturday we were able to do a walk back but were not able to save anything as network had not been configured, but we could do a walk back but couldn't file a bug report. The thing we noticed is that the second argument of all functions was empty. Meaning a void !!! or a null string ?? Second time with a known good disk for sde and another port on mother board the error occurred again. The third time with new disk sde, cable, port it gave the same error message but with Network set up so we could capture the problem. This time we were not able to do a walk back. The only option was to reboot and we are back to square 1. Any Ideas would be appreciated. Thank You Larry Linder
Installation of 7.1
More on installation of 7.1. We decided to not deploy SL 7.1 Down loaded the nice serial manual from RH site. Well written, and everything works as stated. There still does not seem to be a way to get a simple Ethernet connection. Error message is NO Connection We started out with a working box running SL 5.11. Since all of our users gave it a thumbs down and did not do not want this OS - the vote was unanimous. The Ethernet install failure was the a show stopper. Installations we tried were the standard, automatic etc. Last night was the 16Th time we tried to install it and make some sense of it. So far we have tried about every thing and finally let it do a standard install on the OS disk. It didn't improve anything. Made you think of Windows 7 - Bill computer on this time its big Red's computer. 1. When looking at the / there were two partitioned /boot, /home / and that was it. If you do a df -n on look at the installed stuff it is just a bunch a numbers and no clue as to what they all did. No /var, /opt, /tmp and others we use on other disks were no where to be found. Just a series of characters - no meaning. 2. We tried to load a couple of apps we use some are home grown, some are purchased, cad packages did not want to install. We ordered VMWare so we could install some variants of Windows for special stuff and use our file system layout. Down loaded it on another system but have not installed it due to Ethernet problem. 3. We decided to just reload 5.11 hook up other disks and forget till SL 8.1 comes out sometime. We could not install a previous OS . It seams that SL 7.1 has written something on the Track 00 of disk that it was installed on we cannot see it but it prevents you from backing to a prior OS version. Once you install 7.1 you have been Intercourrsed. 4. We need a way to gracefully remove SL 7.1 if we can't then we will have to do a low level format on disk. One of the guys suggested that we take the disk out and put it on fence post in south forty and he would loan me his twelve Gage. Just because a low level format takes so much time. 5. We have invested about 16 hours on various installs at the shop rate and that is a lot of money spent for a Zero gain. Dan remarked that it is so secure that even as root you could do nothing. Reminded him of a 10 Ton Steel safe full of trash at 15 K ft. below the surface, secure but effectively worthless. 6. One of the major birches is how do you tun off the goofy sound when you manually step back too far. Can you imagine 50 of these noises going off at the same time. This is below first grade stuff and needs to be removed. The last thing you need in a machine shop is a surprise when some one is running a mill, lathe, power sheer, drill press. One of disturbing trend is that everyone likes to use the word Wizard I am old enough to have watched Mr. Wizard in the 50's and the usual Wizard experiment blew up in our faces. A word that should be forbidden in software is Wizard and one other that I can't remember that is used in Windows and stuff I have seen in Red Hat. I need a way to uninstall 7.1 from our test system. One way that was suggested was to load Windows 7. Ouch. We have been using Unix since 79 on a PDP8, a Convex super computer, Sun Super Server a 16 processor Server, and for the last 10 years We have been using SL Starting with SL 4.1 Linux. Tried to use Susi, Slackware others that were around. and all had major deficiencies. So here we are with SL5.11 and some boxes @ SL 6.4. They all work together and the network was easy and the video was excellent. Thank all of you for your help over the years. Will go back to sleep till SL 8.1 comes along. Hope its before 5.11 support is ended. Larry Linder

I hate to complain but doe anyone check their work anymore. Or just compile it without errors and shove it out the door. There a several major things missing or wrong: 1. It groans and complains about size of /boot - its set to 101 Meg. Reloaded 7.2 again and there does not seem to be way away to change size of /boot partition. I periodically nags at you because there is only 25K left. Now way to fix problem or to shut of NAG function. This is not SL, this is upstream at Red Hat Enterprise Linux. There's a great deal to dislike about the current, highly graphical anaconda. The change from a flow chart, one step at a time, ncurses based, checklist installer of much older versions of Red Hat to the newer, bulky, graphical toolkits came with inconsistent layout, confusing options, confusing dependencies that used to be automatically handled as blockers and dealt with before proceeding in the ncurses, text based tools. It looks to me,, like in this case, you need to custom partition the disk. No idea why /boot is so small, but can you reduce the size of / and then expand /boot? The OS is installed on a 200 Meg Disk and nothing else is on the disk. Removed all the install partations and still could not change any partation size. It just does not work. Unfortunately, each layer of anaconda installer on top of undelying tools like parted for disk management, yum for package selection, and NetworkManager has injected its own layer of interface on top of *another* interface, on top of the actual configuration commands and tools. And the results are predictable: edge cases result form assumptions that were made, and which break down in practice. The size of /boot is one of those. 2. Could not find a way to set up groups or add new users. Had to go back to hand edit of passwd and groups to make it happen. No way to assign user id numbers. What? What happened to useradd and luseradd, groupadd and lgroupadd ? As root they are no where to be found which I thought was pretty strange. 3. Could not find a utility to set up Internet connection - When you used a KDE or Gnome the Mac address of the router was different. We have not been able to connect it to Network. Yeah, NetworkManager is not my friend. You might benefit from the lightweight 'nmcli'. I'm fairly unhappy about NetworkManager: Networking setup is pretty simple and who ever ginned this up apparantly does not know it. 4. Default monitor was set to a pixel size you need a microscope to make out the text. If you used the Gnome it said monitor was IBM 12 France. KDE said monitor was IBM 12 Brazil. No other options were available. Maybe go back and hand edit Xterm stuff. A major step back by 20 years. Ouch. You're on a laptop? No we have everything from 17 - 21 CRT's and LCD's from 17' to 34 we don't use anything but CRT's in the shop because a small piece of metal hits it and its lights out. 5. With out com and a way to make display readable it becomes useless to run word processor, spread sheet, or anything. Can't optimize width or set width, You can go to full screen and the result is the same. There no way to set up terminal for other colors or text. Borders of GNOME are same color as other windows so you have to look twice to see which is which. List of dislikes goes on and on. Gnome is not my friend. I've not tried porting 'vtwm' to SL 7 or RHEL 7, but my tools for putting it on SL 6 and RHEL 6 are available at https://github.com/nkadel/vtwm-5.5.x-srpm. 6. We (everyone in the shop) unanimously hates the GENOME desk top. There does not appear to be able to select an alternate. See above. 7. Could not find a way to turn off high pitched sound when you tried to step back too far on a line. This part of NAG function and can't turn it off. 8. Tried to play a CD - old Marty Robins and it skipped tracks and got hung up and could not X it out. Had to Reboot. There is something basically wrong with the OS if you can't kill an application.

SL 7.2
Dear Sir: Loaded SL 7.2 for third time and finally got it to where we can run it. I hate to complain but doe anyone check their work anymore. Or just compile it without errors and shove it out the door. There a several major things missing or wrong: 1. It groans and complains about size of /boot - its set to 101 Meg. Reloaded 7.2 again and there does not seem to be way away to change size of /boot partition. I periodically nags at you because there is only 25K left. Now way to fix problem or to shut of NAG function. 2. Could not find a way to set up groups or add new users. Had to go back to hand edit of passwd and groups to make it happen. No way to assign user id numbers. 3. Could not find a utility to set up Internet connection - When you used a KDE or Gnome the Mac address of the router was different. We have not been able to connect it to Network. 4. Default monitor was set to a pixel size you need a microscope to make out the text. If you used the Gnome it said monitor was IBM 12 France. KDE said monitor was IBM 12 Brazil. No other options were available. Maybe go back and hand edit Xterm stuff. A major step back by 20 years. 5. With out com and a way to make display readable it becomes useless to run word processor, spread sheet, or anything. Can't optimize width or set width, You can go to full screen and the result is the same. There no way to set up terminal for other colors or text. Borders of GNOME are same color as other windows so you have to look twice to see which is which. List of dislikes goes on and on. 6. We (everyone in the shop) unanimously hates the GENOME desk top. There does not appear to be able to select an alternate. 7. Could not find a way to turn off high pitched sound when you tried to step back too far on a line. This part of NAG function and can't turn it off. 8. Tried to play a CD - old Marty Robins and it skipped tracks and got hung up and could not X it out. Had to Reboot. There is something basically wrong with the OS if you can't kill an application. Disk plays fine in my Dodge truck and does not have any visible defects. DVD writer is good as we were able to make a dual layer DVD for 7.2 with it using SL 5.11. 9. Gave up on SL 7.2 Notes: The default set up was like a quadriplegic Windows 7.

I would not like to tell the boss that we had to trash 45 to 50 perfectly good monitors and give up our ability to add users, groups and network extensions etc. example: We have a number systems in shop and one by Mill and Lathe so there are no paper prints. Guys can review prints on line and set up CNC stuff on line. Saves a lot of time. The evaluation box is a dual core AMD, 16 Gig of Ram, 4 disks - totaling 2 TB. and a GForce Video card, all pretty current stuff and a working 5.11 system. We will reload SL5.11 on to test box and start looking for another Linux distribution that has not been mangled by Ex Microsoft employees, working at RH. Due to obtuse problems we quit evaluation and will not deploy SL 7 - The best solution is to drop back and evaluate SL 6.5 and see if we can live with it. We have a SL 6.2 used on special project. We need to run spice, a Circuit layout editor, many spread sheets and a number of in house programs to manage inventory, component ordering, e-mail, VMWare to run several cad packages and a stress analysis program. Some employees run 12 desktops and two monitors. So fare we have not see a limitation for 5.11 but have had to install a number of newer libs to accommodate new SW. Larry Linder
Re: Malware 4
Next It is back: Removed all of the files that are in / , /boot, usr/, /etc/rc.d/init.d It has set up files again in /boot. new IptabLes and IptabLex are now in /etc/rc.d as well as in /etc/rc.c/init.d I built and run the rpm script and the number of UNVerified pretty large. The common thing was that they all had to do with iptables, and other security files. Since I have reloaded the OS once and it came back. I will lowlevel format the disk and reinstall and change all passwords and permissions. The bad part is that the major disks containing our engineering files for last 15 years may also have the program burried somewhere in the 39 G. There are also a number of new ports added to the system - ! The only real file I saved from the old OS was the CUPS configuration file. I examined them but did not see anything that should not be there. Will have a list of rpm verification failures tomorrow. There were a couple of failures that dealt with samba - so they were able to gain access to the M$ systems as well. The thing that has me worried is that they are changing things each time it is back. Slight differences. The US should just unplug China from Internet and a lot of the problem goes away. To night we will simply unplug the box.

Malware 3
One of our servers has Malware on it and it hammers the eth0. using /sbin/ifconfig you look at a few thousand reads and 3 G of transmits. Transmits roll up at about 0.3 G every 2 seconds. What keeps this bound is that the ATT network it is tied to is only good for about 200K up load and 1.5 meg down load. If you look in /boot you will find two linked files named IptabLes and IptabLex. Once you kill off these processes listed in ps -aux then you can connect to Internet again. Search on Google using 'IptabLes' and 'IptbLex' If you do not use single quotes all the upper case gets replaced with lower case and you do not find anything. In our case data was added to the /etc/host table pointing to a 127.0.0.0xxx. The xx are a company in China. We ran a couple of malware detectors and none of them flagged it. When you search for 'IptabLes you will find a very detailed description of where the file are and what they contain. Removing these files fixes the problem for a few hours. In our case it starts after 12 PM during lunch. EST. and ever so many hours. I have looked at cron and cron.hourly etc and do not find anything suspicious. In my case I am looking for a date stamp of 22 May 2014. This is when this network crashed. We unplug this server from switch and the network is back up and running. This box is a quad core AMD and ps -aux tells us that it is using 33 % of CPU time, a 1G card, the switch is a 1G and slow network of 200 K upload and it just quits. You have to remove all the programs and a few hours later its back. If process is not started by cron then how else would launch a program that can reload the files. Some appear to be assembled, some are python, and some are html (guess). This box has about 2 T Bytes of engr files on it. We removed SL 5.10 and reformatted the disk, reinstalled 5.10 and it worked very well for a a few weeks, it came back. I need to find out where the main program is and blow it away. I would assume that it has multiple copies of itself. ??? but where. Is it contained in a OS file? as some others viruses where the file contains the orrig in the first 4096 bytes and the next block is the virus, and the rest of the file follows at 8096. So if you run something like cp the virus spread to all file in /bin. If this were on a fast network - everything you own would be sent to China. Any Ideas ?? I didn't rewrite what is contained in the web page but just directed you to it. I don't think I would use a box in secure environment to examine this, I am just skeptical of everything I see anymore. If anyone is interested I will share the details. Thank You Larry Linder
Available Packages
We have added a number of packages to SL5.10 that we use daily. The support for video drivers that had worked very well from SL 5 to SL 5.10 went broken in SL 6.2 and remain broken. It would make another popular Mother Board. Fixing this problem was real exercises to get elrepo down loaded and fix all new hardware systems. We have to support a bunch of mongrel SL 6.5 systems. PSpice was a problem and we had to add a lot of lib's to make it function. So Far we have been able to down load a number of device spice models from Maxim and build models for some very efficient power conversion devices and a few VLF circuits for looking at electromagnetic data from storms. Maple - we have been using it for a long time to some analysis projects. We are holding our breath to see if it gets broken. Eagle - 5.11 We have not upgraded this package due to some lib issues. It seams they built it using another Linux package. This allows you to develop circuits, do a board layout and simulate its performance. They didn't use PSpice so we had to build a model conversion tool to fix some format problems. It would be helpful if we could get required libs into SL7. Word processor: It appears that the latest distributions of LibreOffice deleted the support and translation of early StarOffice files. We have been using StarOffice, openOffice, libreOffice for a long time. The splintering of the effort has not helped - its the best advertisement that M$ has for their office product. Since there is no way to contact these folks directly I thought I would publish it here. Its very evident that the authors and developers have never worked in a commercial or practical environment. When looking at our company's files on a server the StarOffice - LibreOffice is nearing 39 G. of data we access every so often. We have been looking for a scheme to bring them forward - a migration scheme but need to preserve file date internally. I have to ask this question of developers - why arbitrarily delete a capability just because of ignorance. Be you are offended look up word in dictionary. A long time ago it made sense to make a smaller foot print but now since disk storage is almost free. Pardon my rule breaking on this subject. So far we have most systems upgraded to 5.10 and a dozen 6.4 - 6.5. The SL added packages have been a real asset. I think we may be one of few commercial users. Thank You Larry Linder

Malware -
Background: We scanned the system and the Malware Detection SW did not find any thing it could identify. It took most of the night to finish a couple T bye size disks. It flagged one file in a users directory as suspect but when we examined it was a lot C code for data reduction. The users app files were on another disk. It was unplugged and we reloaded 5.10 and that caused a little bit of problem. Undocumented as to what it was. Reloaded 5.5 and then upgraded it to 5.10 - worked. It has been a pain to get the analysis and cad programs that needed special libs to function back on line. Our book keeping was inadequate and we had to resort to the braille method. One we reloaded the box and plugged the user disk and data disks back in things are starting to function pretty well. One thing we did was to put all application tar files on a directory on separate disk from the OS. Now we have a copy of var In hindsight we should have put /usr/local on a separate disk along with /opt. Not being able to find a finger print sort of left us very gun shy about what we allow in plant. Since this was an open server and it grew like a bad weed and we knew it was going to happen but never in a bad dream would we have guessed what it was doing. We will never know what it sent or received. Thank for the advice and expert help. This problem took a lot of time to fix and recover data. Everything on this box was saved on CrashPlan - I think we need to dump data in back up and start over. Back up may have the same problem and you get it back when you restore files. Larry Linder

Akemi Thanks for all the schemes but my agricultural fix to problem is to make a dated back up of grub.config file and use nvi to edit file and just set default to kernel we had been using. Unfortunately that is not the end of the problem. We can ping our dns server so we know the network is working. ssh allows us to connect to all boxes on the network. We can log into router with browser so we are know hardware is OK. Other boxes running 5.10 can access google.com For security they are in the promiscuous mode. We are not able to launch google or dogpile search engines from this box. We cannot use browser to view our own website. We suspect that it is a security problem with 6.5, when we installed 6.4 we were able to select security level during the setup. With the simple upgrade selection we assumed that it would stay the way it was. Any suggestions on where to look. Thanks Larry Linder
Upgraded to SL 6.5 - no Ethernet - Working
Thank you all for your assistance. Connie had right answer. In the grub boot loader all of the available Kernels are there and can be booted. Top of the list was 6.4 . When we had a major power outage the system, shut down by the UPS, and was manually rebooted and the orrig. 6.4 Kernel was loaded and no Ethernet - transmit. According to ifconfig the Rd had a large number and the Tx had 0. On this system its hard to see as the boot happens very quickly and if you are not looking for it you miss it. In the grub boot loader all 6.4 , 6.4 elrepo, and 6.5 kernels were there. If you don't select elrepo, it boots with 6.4. Rebooted using the elrepo kernel, solved the problem. Ethernet is now working. Next Question: How do I modify the boot loader to put the elrepo kernel first in the list? The hardware works perfectly with SL 5.4 to SL 5.10. It will work with a 32 bit SL 6 but not with the 64 bit SL 6.1 - SL 6.5. I would assume some where in the code a variable definition's length did not get changed to 64 bit. Or some how a 32 bit module or driver was linked in. The odd part is that SL 5.4 as a 32 bit system worked, SL 5.5 - SL 5.10 as a 64 bit worked. Hope upstream builder fixes the problem. Thank You All for the expert help. Larry Linder
Upgraded to SL 6.5 - no ethernet
On one of our development systems the Internet quit working after a power failure and a reboot. We suspect that that a new kernel was downloaded by Yum and never took effect till a reboot occurred sometime later. History: We know that the realtech driver for chip set RTL 8111/8168B works with SL 5.4 - 5.10. The problem is with SL 6.1 - 6.5. Same box same hardware. A long time ago we installed a special kernel from ELRepo.org to fix the problem with SL 6.4. SL 6.4 later was updated to SL 6.5 and still no Ethernet - ifconfig shows that it can receive but not transmit as before. Would it be appropriate to reinstall the kernel-lt-3.10.32-1.el6.elrepo.x86_64.rpm date 28 Feb. 14 to fix the problem. Second question: How do you turn automatic updates OFF. Larry Linder
Re: Fedora Scientific Spin
We use SL 5.10 and SL6.4 in a commercial company. The stability is the obvious reason. We do not want or need the latest features that clutter the landscape. If SL were to link up with or even consider Fedora - we would abandon it. No one in their right mind would use a sand box as quoted by a RH Engineer for a critical endeavor. It is to allow freedom of development of SW only. If you ever complained about an application in Fedora all you get is a ration of crap from developers who are using it for a school project. We used to point out expansion or correction to some Fedora projects but were told to go away we did. We use SL6.4 for a lot of reduction of atmospheric and seismic data. This is serious stuff with serious money behind it. Some problems run for many days. If you need a stable system where you can depend on it and concentrate on you project then SL is what you need.

Expansion plans
New project for next January. We are getting ready to expand our lab and plan to install a terminal with large displays at each bench. The bench will support one or two projects and I hate the thought of setting up 6 new SL 6.4's so there is access to schematics, parts lists, layouts, and drawings. In the past we have used NFS to do this. I have thought about setting up a VMware server and running SL 5.10 and Windows under it. The problem is how to tie it all to one or two servers in the shop without this turning into a big dog performance wise. Since we plan to use the same hardware we need to mod all SL6.4 so that Ethernet works correctly. SL5.10 works out of the box. We really like the Gigabyte boards and AMD quad cores. We quit buying other brands because of bad brown capacitors that bulge and start leaking before the board / processor fails. When you start replacing 50 or so boards it is a real problem. Wile we are at it we need to set up other boxes for shop, receiving and shipping with printers. I hate to say this we are still running a sneaker net. We are basically an electronic engineering company that is looking more like a factory. Thanks Larry Linder
Re: New Install of 6.4 - no Internet step 2, 3, 4 -- 5 - What works Does not
Gigabyte 970A-DS3 with Quad core AMD. SL 5.8 loads and everything works. Fedora 19 loads and everything works. kernel linux 3.9.5-301.fc19 SL 6.4 loads and when network is set up. Realtech on board chip set RTL 8168/811E as marked on chip. Network will not connect. Ping 192.168.0.1 - router and it runs ping and no return from router. ifconfig eth0 receives data but TX is always 0. Tried different drivers for realtech chip - nothing worked and most would fail when you restart no eth0. Fresh install of 6.4 with network set up - same result - no network TX. Loaded new Kernel from Elrepo.kernel-it-3.0.89-el6.elrepo.x86_64.rpm Installed with rpm -i *.rpm. rebooted system touched key to select new kernel at boot. ifconfig eth0 receives data and transmits data. network now connects and everything now works. Conclusion is the kernel supplied in 6.4 has a mistake somewhere, realtech driver and hardware are good. r8168 driver works with SL5.8. Installing new kernel solved the problem. r8169 driver is used with Fedora 19. Have learned more than I wanted to know. Thank you all for your help.

Thank You All Larry Linder The mystery of why there is no Internet on 6.4 using the Gigabyte board become more confusing. We were looking at our hardware list and decided that boxes deployed two years ago had essentially the same NIC stuff and they worked with 5.5 - 5.9. We loaded 5.8 into new Gigabyte hardware and guess what it worked perfectly !!! The 6.4 DVD was down loaded and checked and everything matches. There is something wrong in the Gnome system network set up. SL 5.8 has a very different network setup. We got pretty suspicious when we loaded updated driver and new Kernel 3.0.8 and same result. Too many people stated that this worked. SL 6.4 is loading for the nth time and we will use another scheme to setup network. Thank You All Larry Linder
