[luau] Donation of Oracle 9i Linux Server to Mililani HS
To LUAU list and Wayne Liauh: -- I will soon send the following message to Mililani's administration and tech teachers. * Anything I should add? * Wayne, do you approve? * Wayne, what are the other specs on the machine (motherboard, hard drive, PSU watts, etc.)? * I will need some volunteers to help train the teacher in Linux Oracle usage and possibly Java later in the year. Also I myself may need help in configuring Oracle, since I've never done it before. Thanks, Warren -- I had originally planned on giving Mililani a Pentium2 400MHz machine for use as an Oracle 9i server for Cindy Mochida's Oracle class in L204, but today Wayne Liauh, a local lawyer has graciously offered his 1GHz Athlon machine with 256MB RAM which would make an even better Oracle server for Mililani. With this amount of server power, in addition to Oracle 9i, I will be able to show your school an effective way of using Unix as a Java learning tool. This Unix method of using Java is taught by several Computer Science department lecturers at UH, and I would suggest it to be a way of speeding the learning process for your Java students. We can possibly make this donation final if the following four conditions are met: 1. Mililani HS agrees to use only the Linux operating system on this system, for Oracle 9i, Java and possibly other educational learning. 2. Mililani HS agrees to buy additional RAM, type of my choosing (roughly $50-120) to make this server production ready. Mililani may optionally choose to buy a backup drive like a CD burner to safeguard student data. 3. One Mililani HS faculty member must accept free training from MPLUG in the proper usage of Oracle 9i and Java development on this server. Two faculty members must learn simple server maintenance tasks. Please let me know ASAP. Thanks, Warren ---BeginMessage--- Hi, Warren- I have a spare 1.0 GHz Athlon T-Bird with 256 MB PC133 SDRAM. It works great. If the school is willing to chip in another 256 MB of RAM (should be less than $50), I can donate it to them. ___ LUAU mailing list [EMAIL PROTECTED] http://videl.ics.hawaii.edu/mailman/listinfo/luau ---End Message---

I think its 27015, but it tells you when you start a net game. I think the first server is 27015 or 2715, and every additional server on the same IP is 1 port higher. Try playing a gane and look at what port it says. I think its the first thing you see when you join an internet game. If you're doing a firewall kind of thing, you probably want to keep every port from 27015 to about 27020 open in case you want multiple servers on one machine. -Eric Hattemer - Original Message - From: ryuhei yokokawa [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, August 15, 2002 2:12 AM Subject: Re: [luau] sorry off topic but important eric i asked for the port number of the server On Wed, 14 Aug 2002 18:58:11 -1000, Eric Hattemer [EMAIL PROTECTED] said: After all the discussion, we've failed to answer the initial question.

I am suffering from procmail overload! Most of my procmail examples and info came from Google so my knowledge is all patchwork. I've seen examples that used locks and ones that did not. For certain situations locking is suggested and others it is not required.

Further to my comment. Limbo 2 runs great on the GHz Athlon machine that I am going to give to Warren. Indeed, great is an understatement; it runs absolutely beautifully. I have never seen anything like that. WordPerfect 8, running from a KDE taskbar, took one second to load, and zero (i.e., ZERO) second to import an HTML document. As far as I am concerned, this is more than amazing, it is truly unbelievable. Of course, there were some glitches in the beginning, such as that I had to manually load the tulip driver for the Linksys NIC, and re-work on the desktop, task bar, etc. But that's not much a price to pay. OTOH, Mandrake 9.0 beta 2 is not nearly as ready as Mandrake 8.2 beta 2 at an equivalent stage. Mandrake is laying off a bunch of people, including some core developers. Without a viable business model (it is now living primarily on gratituous club membership), I don't know how much longer it can survive. Very sad!
Re: [luau] Linksys and Red Hat (Not)
I agree. Red Hat does not suck as a desktop machine. Granted, it does take a little more work to set up then mandrake or windows. Comments like Redhat just sucks as a personal desktop machine serve no purpose.

[luau] Status of Mililani High School
Yesterday I was at Mililani from 8am to 5pm working on their SunRay and Windows Celeron lab. As I mentioned earlier, the SunRay lab was extremely poorly put together with an underpowered Sun E250 server, initially with only 1 processor and 1GB of RAM. Sun donated a second processor and another GB of RAM, but it still couldn't handle 30 clients. After a wasted investment of $40,000, the school was suffering for an entire school year with an entire lab of computers that were almost useless. It couldn't handle everyone running StarOffice at the same time, and logging out took something like 10 minutes. Mililani was so displeased with the lab, that they were seriously thinking about getting rid of it for a loss, but nobody would want to buy it from them anyway. Many of the issues here was an extremely poor understanding of Unix by whoever set this up. There was no SSH, SSHD, gcc, grep, awk and many other tools. The support person did almost entirely remote administration through telnet and FTP. I had never touched Solaris in my life, and I knew things were horribly wrong on this setup. To make matters worse, even though the school supposedly bought a 3 year support contract, the DOE lost their SunRay support person due to some braindead DOE reorganization. Now something like 50 schools with SunRay (mostly on Maui) have almost ZERO support. I told the Sun guys and Mililani that the group and I will support the Mililani lab on a volunteer basis. I have no doubt that we can make the lab work great because we actually have a clue how to properly use Unix. Yesterday Cliff Goto (DOE's Sun + Lotus Notes admin) came with two Sun technicians to swap out the E250 with a DOE owned E450 with four 300MHz processors and 2GB of RAM. After the server swap things appear to be running a lot smoother, StarOffice 5.2 appears to run better, and people are able to login and logout into CDE quickly. The lab is currently in a somewhat usable state, probably for the first time in its life. Remaining problems: From here a serious amount of work will be needed fixing up the Solaris installation. It is currently running Solaris 7 and an old version of the SunRay protocol software, and it is uncertain whether Sun will supply a free upgrade or charge money for it. IMHO Sun should provide it for free considering the amount of problems the school has had with their product. Prior to this server swap, Ginlack, the Principal of Mililani was considering approaching ActionLine to make public this bad situation that was bordering scandalous, with a $40,000 lab being almost completely broken for over a year - what an interesting public relations nightmare that would have made, $40k wasted taxpayer money, hundreds of kids being denied an opportunity of technology learning. I suspect that the current Solaris 7 installation is poorly secured and possibly already compromised. Eventually I'd like to do a complete reinstall and I could use help from the group from people knowledgeable with Solaris. For now though, all the GNU tools should be installed including a working compiler, then OpenSSH and VNC so it can be securely administrated remotely. Java SDK should be installed. StarOffice 5.2 should be upgraded to StarOffice 6.0, but I need to write some scripts to handle automatic profile creation so people don't have to go through the somewhat confusing Workstation install for each user. I already have these scripts for StarOffice 6.0 on Linux, so this shouldn't be too hard if the GNU tools that it depends on are installed. After these things are stable, I'd like to replace the current CDE desktop with Gnome2. Mililani had a Windows Celeron lab served by an ancient Novell 4.10 server doing only a print queue. This lab was not uplinked into the school network, so they were running only IPX. Unfortunately the lack of Internet makes it extremely difficult because they teach Oracle and Java in that room. When they do plug the room into the Internet, the Windows machines easily DHCP and go online, but suddenly printing stops working and the Novell server beeps like crazy. After some analysis Elayne and I figured out that the Intel print server appliance was talking only IPX, and it was severely confused when the campus network is connected to that lab. It would somehow be confused by some other Novell server elsewhere on campus, lose its connection to the local Novell server (talking IPX) and stop printing. We attempted to use its built in TCP/IP accessible control panel in order to enable SMB protocol printing, but it seemed to be completely unresponsive to anything over TCP/IP protocol despite its diagnostic printout saying it had a valid IP address. I ended up setting up a temporary Linux NAT box using MonMotha's script to isolate IPX into that room, while allowing the Windows machines Internet access. This is a temporary kludge until I get around to replacing the Novell print queue with a Samba print queue on that

[luau] use dd for disk clone?
I am looking for a way to make a disk image or disk clone, found the following in a linux list archive. quote Subject: Re: Linux disk cloning tool ? Yes--look at the man page for the dd command. It copies raw disk images and why not use it for ghosting? It's a simple, one-line command entry. end quote Being a newbie, I looked at the man page but was not enlightened. dd seems to be file oriented, but I guess you can just treat two mounted disks as files? What would that look like, use /dev/hda and /dev/hdb as stdin and stdout, something like that? If you use / it would cause a problem because you'd be including your destination in your source, right? Isn't there also an issue regarding open files, etc.? When I clone a disk in irix, the manual says to do it in single user mode, I presume because you want all the files in a consistent state. Anyone see a way of using dd to make a disk image file instead of cloning a disk? I found some other software at http://systemimager.org/download/ that sounds like it would do the job, but I hate to clutter up my system if it is redundant. Would tar do? Tarball too big? Would tar be able to make an exact copy? Would it leave out .files? Delirious Dave

Then, if you want software RAID, Linux has excellent software RAID (levels 0, 1, 0+1, 4, and 5). With a modern machine, software RAID can actually be FASTER than a cheap hardware RAID controller (albeit with a very slight penalty in extra used CPU time). This is because most RAID controllers only can do the checksums calculations at a certain speed limited by their onboard processor. CPUs in today's systems are extremely fast, much faster than your average RAID controller. The difference in speed is almost nil between hardware and software RAID when using levels 0 or 1, where no checksumming is involved. ... --MonMotha

Mililani was so displeased with the lab, that they were seriously thinking about getting rid of it for a loss, but nobody would want to buy it from them anyway. Definately someone was not thinking, that system is barely powerful enough to handle a handful of active clients using today's cpu hungry apps, let alone 30. Many of the issues here was an extremely poor understanding of Unix by whoever set this up. There was no SSH, SSHD, gcc, grep, awk and many other tools. The support person did almost entirely remote administration through telnet and FTP. I had never touched Solaris in my life, and I knew things were horribly wrong on this setup. This is not uncommon at all for a commercial UNIX system. Most commercial UNIX systems don't need a C compiler because all the software for them is sold binary only. The C compiler only takes up space and encourages people to use up valuable CPU cycles. Also, until the advent of free compiles such as gcc, a C compiler was a VERY expensive tool. Commercial UNIX systems just do without them. SSH is no where NEAR as popular in the commercial UNIX world as it is in the Linux and BSD world. I have no idea why, but most commercial UNIX gurus seem to just like using telnet. Remaining problems: From here a serious amount of work will be needed fixing up the Solaris installation. It is currently running Solaris 7 and an old version of the SunRay protocol software, and it is uncertain whether Sun will supply a free upgrade or charge money for it. IMHO Sun should provide it for free considering the amount of problems the school has had with their product. Prior to this server swap, Ginlack, the Principal of Mililani was considering approaching ActionLine to make public this bad situation that was bordering scandalous, with a $40,000 lab being almost completely broken for over a year - what an interesting public relations nightmare that would have made, $40k wasted taxpayer money, hundreds of kids being denied an opportunity of technology learning. If Sun won't cooperate, and you guys can get it cleared legally (blah blah - red tape here - blah blah), I would be willing to assist (not guaranteeing any results or that I'll be able to do it on my own) in reverse engineering the protocol enough to stick a Linux server in there. It probably won't be a normal LTSP server as I gather that SunRays are more like dumb VNC clients (bascially a framebuffer on a network), and then don't run X. Be aware that I'm now back at school so my free time just went down by about 90%. Of course check that this hasn't been done already before we do this, but hopefully Sun will cooperate. As with many big name installations (Cisco comes to mind...), things usually start breaking when you plug something in that doesn't have that company's logo on it. I suspect that the current Solaris 7 installation is poorly secured and possibly already compromised. Eventually I'd like to do a complete reinstall and I could use help from the group from people knowledgeable with Solaris. For now though, all the GNU tools should be installed including a working compiler, then OpenSSH and VNC so it can be securely administrated remotely. Java SDK should be installed. StarOffice 5.2 should be upgraded to StarOffice 6.0, but I need to write some scripts to handle automatic profile creation so people don't have to go through the somewhat confusing Workstation install for each user. I already have these scripts for StarOffice 6.0 on Linux, so this shouldn't be too hard if the GNU tools that it depends on are installed. After these things are stable, I'd like to replace the current CDE desktop with Gnome2. If you'd like, I can try to help with analyzing it. Email me privately. Mililani had a Windows Celeron lab served by an ancient Novell 4.10 server doing only a print queue. This lab was not uplinked into the school network, so they were running only IPX. Unfortunately the lack of Internet makes it extremely difficult because they teach Oracle and Java in that room. When they do plug the room into the Internet, the Windows machines easily DHCP and go online, but suddenly printing stops working and the Novell server beeps like crazy. After some analysis Elayne and I figured out that the Intel print server appliance was talking
Re: [luau] use dd for disk clone?
dd seems to be file oriented, but I guess you can just treat two mounted disks as files? It's not a good idea to do it on mounted disks (at lease read-write mounted disks), but yes, you can just use the device names as if they were files. What would that look like, use /dev/hda and /dev/hdb as stdin and stdout, something like that? Well, if you are trying to replicate one disk onto another, then that would work. (Assuming the drives are identical. I'm not sure if it would work or not if, the drives were different sizes/had different geometry). so the command would be dd if=/dev/hda of=/dev/hdb or cp /dev/hda /dev/hdb If you want to make an image then you would do something like dd if=/dev/hda of=mydrive.img or cp /dev/hda mydriveimage.img If you just want to do one partition (say hda1), you would do: dd if=/dev/hda1 of=mypartition.img If you do your partitions separately, then it should be easier to restore the data on a different size drive. For instance, dd if=mypartition.img of=/dev/hdb1 or cp mypartition.img /dev/hdb1 One advantage of doing it by partition, is you should be able to actually mount the image file as if it were a partition using the loopback filesystem. mount myparition.img /mnt/mypartition -oloop If you use / it would cause a problem because you'd be including your destination in your source, right? I'm not sure i follow you here. If you want to do a raw copy, then / isn't even related, because / is a filesystem concept and raw copies don't know about filesystems, they just know about bits. Isn't there also an issue regarding open files, etc.? When I clone a disk in irix, the manual says to do it in single user mode, I presume because you want all the files in a consistent state. Yes. Like i said, better to do it mounted as readonly, or not mounted at all. Single user mode would be a good way to ensure that. Anyone see a way of using dd to make a disk image file instead of cloning a disk? See above. Would tar do? Tarball too big? Would tar be able to make an exact copy? Would it leave out .files? Yes, tar would work I think, but would be a lot slower, because it would work at the filesystem level instead of the bit level. There are other issues to think about two, like if you had more than one drive mounted, then tar would include the contents of all mounted drives in the archive. --Ray

In litteral terms, you can do software raid on linux with 1 HD and two partitions. However, it probably hurts performance, rather than improving it. The multiple heads on a hard drive all line up vertically and scan what's called a cyllinder (multiple sectors stacked on top of each other). They cannot read two partitions at the same time. You could test out software raid with two partitions, but I don't think you'd be too happy with it. You can probably get RAID 1 going with a very slight advantage.

The software is similar in function HP's Jetdirect, except of course this is for Intel devices. You can also use the arp command (see Linux.pdf below). After it gets an ip you can use a web browser or telnet to config it further. There should be a reset switch on the set which will set it to a default config. After that is should allow TCP/IP and use DHCP.

Re: [luau] Software RAID (Donation of Oracle 9i Linux)
There is little point. I'm sure someone can think of an absurd situation in which it might help, but its just interesting that the linux kernel allows software raid on a partition by partition basis, even if the two partitions are on the same drive. Its actually quite useful in that you can set up 2 hard drives each with a linux partition and a windows partition, then set linux to do software raid on it. That's what I always do. Windows software raid takes over both hard drives, then requiers a third because it makes them non-bootable. Really a backup device beats any system of 1HD software raid 1, but it might be fun to mess around with if you're bored. Certainly setting up software raid 0 can be fun on a desktop system, though. That's what I do, and I'm quite happy with it as long as redhat sets the DMA on (I always have to force it on on two different motherboards because of its over ambitious bad controller protection). -Eric Hattemer - Original Message - From: Brian Low [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, August 15, 2002 3:23 PM Subject: RE: [luau] Software RAID (Donation of Oracle 9i Linux) What would be the point of doing a RAID with 1 drive :) You get 0 redundency.

If you are starting from single drive, and you want to go to a RAID level that is redundant (1, 4, or 5...anything but 0), what you can do is configure the array with the drive currently in use as a failed disk, meaning that when it initilizes the array, it will bring it up in degraded mode, not using the disk that you're currently on. You then copy everything over, reboot onto the new array (still in degraded mode) and raidhotadd in the last disk. This is how I converted my slack system to RAID 5. --MonMotha

I've just installed SuSE 8.0. Slick and Smooth. The configuration was
easy after using primarily redhat for the last couple years. Browsing
with Opera is very quick and Evolution, as I'm discovering for the first
time is simple, configurable, and quite sharp looking as well.
a question:
During the installation of Main Actor (supplied by the install CD's),
the install choked, and here is the message log:
rpm --root / --dbpath /var/lib/rpm/ -q -p --qf %{NAME}
/var/adm/mount/suse/pay4/MainActor-3.6.6-150.i386.rpm
MainActor
Return :0
rpm --root / --dbpath /var/lib/rpm/ -q -p --qf %{NAME}
/var/adm/mount/suse/pay4/MainActor-3.6.6-150.i386.rpm
MainActor
Return :0
rpm --root / --dbpath /var/lib/rpm/ -q --qf %{NAME} MainActor
Return :1
rpm --root / --dbpath /var/lib/rpm/ -U --replacepkgs --oldpackage
--replacefiles --nodeps --ignoresize --percent
/var/adm/mount/suse/pay4/MainActor-3.6.6-150.i386.rpm
Installing MainActor-3.6.6-150.i386
482
Return :1
... ERROR
any idea what this is? The media is store bought from CompUSA, so
although I'd like to rule out bad media, it is possible, I guess.
The dik looks like it is clean (i.e no scratches, dirt)
TIA

Re: [luau] SuSE 8.0
After I RTFM for rpm, i realized that this line that failed is trying to
upgrade
rpm --root / --dbpath /var/lib/rpm/ -U --replacepkgs --oldpackage
--replacefiles --nodeps --ignoresize --percent
/var/adm/mount/suse/pay4/MainActor-3.6.6-150.i386.rpm
Installing MainActor-3.6.6-150.i386
482
Return :1
... ERROR
but this line should have told it that it needs to install instead of
Upgrade..
rpm --root / --dbpath /var/lib/rpm/ -q --qf %{NAME} MainActor
Return :1
when the return value was nonzero for the query.
When I logged into X as root and installed it, it worked fine. (I was
installing it as another user and when it prompted me for the root pwd,
I entered it)
