Re: [expert] static linking in LM7.2 (kylix)
Morte, I've just been looking at this myself, but I haven't really gotten started. If you get this going soon please post to the list or email me directly with what you had to do to make it work. If I get started before you figure it out I'll keep in touch and hopefully we can muddle through it together. One thing I did notice is that ftp://ftp.borland.com/pub/kylix/devsupport/glibc_patches/ has a patched glibc for mandrake 7.2. (It's clearly marked for 7.2 if you open up the tar package.)

Re: [expert] openssh / ssh ?
And this is exactly why the SSH trademark holders are beginning legal action against the OpenSSH group. Because there is a difference. SSH is a commercial product. OpenSSH is a GPL product based upon an early SSH code base and designed to inter-operate and be functionally equivalent to SSH. But now there is a considerable amount of confusion among the general population, and sharks/lawyers are beginning to circle.

We intend to support 4 binary formats: HP/UX SOM 32 bit Linux ELF 32 bit HP/UX ELF 64 bit Linux ELF 64 bit We're not promising to get all HP/UX binaries running on Linux.

There are no stupid questions. You're almost correct. It's the offset from UTC, which is related to the time zone, but isn't really the time zone if you're one to split hairs. If you're not worried about being technically correct then, yea, it's the time zone. For example, the -0500 is probably US Eastern on Standard time (EST), but not necessarily. It could also be the time in Panama or Peru. The -0700 and -0800 are almost definitely US Mountain on Standard time (MST) and US Pacific on Standard time (PST), and the +0100 is in Europe somewhere. (The + is on the meridian.) For the hair splitters, at other times of the year the US Eastern zone also has, drum roll here, EDT or Eastern Daylight Time! When the offset is -0400, but it's still the US Eastern Zone! One time zone, two offsets. Michael

What you're seeing is the result of inetd in action. If you go to the console of your box regardless of whether it Mandrake (Yeah!! Bravo!), RedHat (OK, pretty good too.) or just about any other flavor of modern Unix-like system (Well, at least better than Windows.) and run ps or top to check the process list you'll note that the telnet daemon isn't running (assuming no is connected over the net.) Now, when you try to connect to the telnet port the request is caught, looked up, and then a telnet daemon is spawned to handle it. You can make it a lot faster if you remove telnet from the control of inetd and just insert a line in your rc.local to start a daemon always loaded at boot. But this consumes memory. Examine your /etc/inetd.conf, /etc/services, and /etc/protocols files and the inetd and tcpd man pages to find out how this works. Use less instead of an editor to be safe when looking at the files. If you've got plenty of resources and the small delay is frustrating then change it. If you're already running out of memory then leave it like it is.

First boot into windows and create a few new hardware profiles.

When windows boots tell it you in profile xyz and it will reconfigure itself for the video, etc it finds in the vmware environment. This way you can boot into windows native and let it run with your abc video, sound card, other hardware, or start windows in vmware and let it use the vmware xyz hardware.

No real world experience with Reiser here, but I don't think this will work very well. What Reiser does is keep track of the changes it is going to make, applies the changes, then marks the transaction completed. What you are talking about is recovering lost information from something which is supposedly already committed. These two are very different.

That >way, I'd have lots of possible input methods on a *single* login. I think you're confusing a tightly run highly centrally managed environment with the mayhem which can be possible. True, in a "relatively" open office you could create problems. But if you simply put a quick check for the user logname against a match with any line from the who command in the system wide profile you could kick out the login. (Note: this is probably harder than it sounds here. But it's always easy for the guy who doesn't have to make it work.) To keep the situation controlled you can forgo the whole desktop idea and just start xwindows and the data entry application from the ~/.bash_profile. They exit that app and get logged right back out. If you really have a bunch of people moving around to different workstations you probably want to set up xdm so that the desktop box is merely running X and the users is actually logging in to a server rather than the local machine. (A poor man's X terminal if you will.) Of course, if it's a curses based data entry program you need no X at all. Overall, it's certainly "doable", though not really trivial if you need X, to keep people from logging in the central server more than once. It's actually trivial if your data entry program is curses based and you use "dumb terminals" to run the app. But the original poster needs to keep in mind that there isn't a "centrally managed domain" like the NT model. In NT a central server is in control of the login of the local workstation. One could set up a remote authorization server and plow through all of this in LM, but it's a bunch of work. I don't think any Linux distribution (or, for that matter, any commercial Unix distribution) ships with that kind of configuration available out of the box. Michael

So if it's for a home system (the environment wasn't >clear, but I assume from the tone that no local tech-support was available) >then the user needs to learn the basic tools. So make it easy. For mainstream this is really a big problem. (As are the still thin i810 support, lack of support for the now popular software modems, and - unless HP is really telling the truth in their announcement this week about supporting Linux - the now ever present host based printers.) The fact that I've gone out of my way to shield the ordinary users from vi (and a bunch of other stuff no sysadmin would have trouble using) presupposes that even after I left those jobs there would always be some sysadmin around to do the geeky stuff. That assumption isn't true in the typical home environment, which is partly why Microsoft shipped Windows 9x full of security holes. It had to be that way to be easy. And as long as most machines weren't connected to much of anything it didn't matter much. Now that they're everywhere and have open TCP/IP links to the whole world it's a real problem. Linux could be the same way. Ship it wide open like W95 and let the user beware; I have a problem with that. Ship it in a straight jacket and make the user figure it out - like OpenBSD; the average person will pass, thank you very much. But to gain widespread acceptance there has to be a balance of some sort, and that balance might be very tricky to find. If you want only geek systems then just stop now because the true geeks will configure it like they want anyway. If you really want a kindergarten safe system then wall off the modem and the NIC and make everyone use the same desktop. Neither of these choices makes any sense from a business perspective unless you're trying to go out of business. Now, in the Mandrake model there is a server install, a developer install, a desktop install, and some more. Perhaps the install needs another axis to select related to the geek level of the target user(s). I could certainly see the utility of a server install with a novice user option. You end up with even root having pico as a default editor. Ultra-geek systems make everybody use emacs from the command line. (Ducking the flying objects from the emacs lovers!!) Or perhaps, since there can be multiple skel directories, prompt for a geekness level at install time, make that level the default skel, and build a geekness level choice into a new replacement useradd frontend that selects the skel directory based on that level. Keep the choices limited to about 5. 1)safe for children, 2)newbie, 3)been around the block but not with UNIX, 4)used UNIX some in a former life, and 5)UNIX god. This ought to work whether it's a home install or a workplace with technical support available round the clock. Michael -- Michael R. Batchelor (Why do I bother with this next line?

Re: [expert] Vi/Vim - The editor from HELL! How do I set the default editor so I can TRASH IT?
I think the whole discussion is important in that it points out at least one of the problems in documentation of a very complex system. I, for one, have been using vi since the 80's, and it's practically always my editor of choice. Why? Because I know it. Frankly, I've never recommended it for users who only want do simple things because it's too hard to explain the difference between "insert" mode and "beep" mode. In life as a system admin I've actually compiled /usr/local/bin/joe into the binaries as a default editor for the mail agents. (Alright, I take a lot of heat around here because I still use elm when I'm on a console. And I've got my elmrc just exactly like I want it!) But life with vi is the legacy of UNIX just the same way that life with MS-DOS backwards compatibility is the legacy of Windows. MS has been trying to kill DOS since Windows95, but it's an alligator with it's teeth in their butt they can't shake off. Nobody past Richard Stallman has tried to kill vi for "power users" but most of the people I know who aren't old timers use pico to manipulate configuration files by hand. So, UNIX (Linux) is both old and new. Removing vi or not leaving it in place would throw too many things out of whack for an experienced UNIX user, but there really ought to be some kind of warning sign for the newbie. Except that we really need hundreds of warning signs for the newbies. Perhaps someone ought to start looking into making the skel configured differently based on what type of install the user is doing. > >A few years ago, I would have agreed with you.

In the narrow technical view, not really. In a broader view, yes, it helps immensly because many of the computer concepts are similar. Consider an example using your home and my home. In each home there is a place to cook and eat, a place to sleep, a place to bath, etc. Now, if you come to my home and look for a particular kitchen utensil I may not have exactly what you want, or I may have it in a drawer you would never think to look at. But both of us have everything necessary to cook and eat. The specific details about our homes differ greatly, but the general concepts are the same. (All from the same Platonic Forms, so to speak.) It's the same way with NT, Unix, VMS, name_any_other_OS_here. Most things you need are there, somewhere. You may have to look around to find them.

Now, after the machine is in the plant there is absolutely nothing in world to stop the plant personnel from shoving a pencil in the safety switch and running the machine with the doors open. And there is nothing in the world stopping you from reconfiguring anything on your machine to work any way you feel like it should work. But, in the same way it would be irresponsible of us to deliver a machine that's unsafe to operate, it would be irresponsible of Mandrake to deliver a configuration that's unsafe. (And if you really want to see somebody making decisions for you, install an OpenBSD system. It's locked up tight as a drum! And they do it on purpose!) Michael
Re: [expert] ANNOUNCE: MacMillan & Mandrake good or evil? on forum
>Andrewbut the point is, as of version 7.1 there will no >longer be an English language vboxed set packaged by >MandrakeSoft. The two Macmillan packages (Complete and >Deluxe) will be the only available English Language boxed >sets. I don't know that this is such a big deal. It's true that the Macmillan crew made a few mistakes on the 6.5 flap, but I'll bet anyone on the list that a world class successful company like that learns from their mistakes *VERY* fast. So I doubt there will be any more like that. On the other hand, MandrakeSoft is a very small company to take on the logistics of advertising and distribution for the entire English versions unless they plan to stay a very small distribution. The WIN/WIN scenario for everyone is for MandrakeSoft to concentrate on producing a high quality master disk, and then let someone who owns trucks, warehouses, etc. take care of getting it into the retail market with MandrakeSoft getting a cut for each box. Quite frankly, unless I'm badly mistaken both companies will make more money, and because Mandrake has more resources we'll probably see an improvement in the pre-release testing phase. The GPL disks *MUST* stay the same, so places like Cheapbytes and Linuxmall will still burn CD and sell them for a few bucks, but because I seriously expect the quality of the releases to get better, those 2.99 CD's will also be better. So, in the long run, the people who want only the GPL disks will get better disks, and the people who purchase the package will get better disks. The difference is that for the large English market a large, efficient distribution house, rather than a small software company, will be handling the packaging. So, both companies do what they do best, both companies avoid what they don't do very well, and the users get a better product because the money saved on the distribution model can go into development. Of course, I might be wrong. But I don't think so. The Linux market is very fickle, and Macmillan knows that. They have too much on the line to screw it up. And if they become perceived as predatory everyone will flock away. Michael -- Michael R. Batchelor - Industrial Informatics & Instrumentation, Inc. Linux is like a wigwam... No windows, no gates.

[expert] MDK for Sparc
I noticed that the MDK for SPARC is labeled as being for an UltraSPARC platform. Anybody know if it will install on a plain Jane SPARCStation 2? (For that matter, will any Linux distribution run on them?) I've got several of those old guys around here and I sure would like to squeeze a few more years of use from them. Michael
Re: [expert] my KVM switch experience
I have some Belkin Omincube 4 port, ps2 only which work great. I have an older Belkin (can't remember which) that's serial port only on a server farm. It's got similar problems you describe. I like the Belkins because they don't require special cables. Many of the others require you to have "their" cables. If I need something in a hurry I can go to a local shop and just get an extension cable and it works. >The alternative is the digital KVMs which maintain power >to each connection.

Re: [expert] GET READY FOR A DISCUSSION
>If I understood the discussion yesterday qmail can't be ported to Linux >because of the language. The developer of said app flatly refuses to >allow qmail to be adapted/adopted/ported or changed inre binary code. No, qmail runs fine on Linux. That's what we use on all of our servers, mostly Mandrake, but some RedHat, too. The original qmail license, however, specifically disallowed redistribution as a binary. Therefore, it wasn't possible to grab an RPM and install it, you had to get the source and compile it. There was a lot of flak about that position, but I don't know if the license was ever changed or not.
Re: [expert] dual 3c509 NICs fail on re-boot

All IRQs are set to legacy in the BIOS, and >PnP support is disabled. With these cards it's necessary to physically remove power from the card after getting everything set up. They have a power on routine which reads the NOVRAM. Set them the way you want them with the DOS util, shutdown and turn power completely off. If you have a newer machine with a software controlled power supply physically unplug the box from the wall and count to 10. Then boot it back up in DOS and use the utility program to check that everything stays where you left it. MB
