Have you thought about hardware watchdog timers? When I used
to have some remote (as in thousands of miles away) headless
machines, I put watchdog timer boards in them. That way if
they ever locked up, they reset themselves automatically.
If you've already got 300 machines set up, it's probably too
late, but next time around...

Please Help.
I am sure this is a newbie type question.
What is the best way to print directly to HP4000/4050N printer? It's got
EIO-2 JetDirect. I don't want to print through a share on another computer.

Date: Fri, 16 Mar 2001 19:23:16 GMT
Hello,
I just bought (yes, not downloaded) my first Linux distro. Suse Linux 7.1
professional. The problem is I can't get it installed on my system. I have
an Abit BP6 mobo with the onboard hot rod IDE raid controller on it. Since
the installation program doesn't recognize my RAID configuration I can't
install anything on my PC. Does anyone know a workaround for this? I've
managed to install Mandrake 7.2 with some minor problems, but it worked.
Suse does *NOTHING*. I only bought it because the kernel2.4 was included as
a standard.
Real shame for that dual PIII motherboard....

I've seen this in RH7.0 upgraded to the 2.4.2-XFS kernel (from SGI). I
*think* it means that mkinitrd is trying to load the loop modules, but
doesn't know how (b/c of a missing entry in /etc/modules.conf). The quick
fix is to 'modprobe loop' before running mkinitrd. The correct fix is
to put the appropriate entry in /etc/modules.conf, but I've been too lazy
to look it up yet.

Get it's IP address/hostname, and set it up as a PostScript lpd printer.

I ran into the same thing trying to install Mandrake 7.2 onto a system
with a DPT RAID controller, which Mandrake install doesn't support.
I installed the system to a single spare drive, then built and installed
a kernel with the proper DPT driver, and finally copied the system over
to the RAID array. (The procedures in the "Hard-Disk-Upgrade" Mini How-To
worked fine for this.)

Did you search the SuSE hardware DB?
It says your mobo would be supported (but there are some problems):
Anmerkung: supported by Kernel > 2.2.12; maybe problematic with attached
ATAPI Zip Drive or DVD. There is a Linux
HPT366 mini-HOWTO: http://www.csie.ntu.edu.tw/~b6506063/hpt366/
There is a SuSE mailing list, where knowledge able people from SuSE,
among others, frequently answer questions.
That could be a better place to ask, as your problem seems to be very
specific...
Good luck

I had a system drive go bad over several weeks last July to the point
that zombie processes waiting on disk I/O completes actually ran over
the proc table. But that little sucker (P133, 32 MB RAM) kept serving
webpages until it flat ran out of forks to carryon. I was in awe that
it could carryon at all, as well as without anybody knowing it unless
they knew what to look for in a ps listing. IIRC it took about a week
for it to finally kernel panic for lack of a fork after I started the
drive deathwatch.
The only reason I knew to look was a routine tail of log files I have
in root crontab started showing these disk errors weeks earlier. This
is IMO an excellent example of how robust Linux memory management is.
As I say insanely often here, "Don't try this on Winders, kids." :)

There may be some mention of this in the Beowulf HOWTO, and if not then maybe
search for a newsgroup that deals with Beowulf systems, there are also
Beowulf mailing lists if I remember correctly, (addresses in the HOWTO).

I suppose you could, but since the virtual machines only have
virtual cpu's and in reality all share the host cpu there's not
much point unless you have a multiprocessor machine and assign
each VMware session a separate cpu.

I am not too sure about that. If I have a symlink from /usr/IBMdb2 to
/opt/IBMdb2, the ls -l command does not give me a listing of the
/opt/IBMdb2 directory when I ask: ls -l /usr/IBMdb2. So at least the
ls command does not follow symlinks transparantly. If I do a stat(2)
command on it from inside a program, it will not return "S_IFDIR
0040000 directory", but "S_IFLNK 0120000 symbolic link", so unless
programs are prepared for these differences, there is no reason to
suppose they will survive a change like that.

As goofy as it sounds... that was it! So why was an install of RH 7.1 +
JDK 1.3 working on an AMD K6-2 one week, but the next week the *exact same
files* installed on an Athlon wouldn't?
I saw a post on Dejagoogle where someone had gotten the JDK to work on the
latest RH after they "downgraded" their glibc from the i686 to the i386
version. Sure enough my install CD had both the i386 and i686 versions
right next to each other... so it's looks like the install detected the
Athlon and went with the i686 version. I did an rpm -U --force with the
i386 version and it's working fine now!

Actually, there's another answer; I remember some months back there
being a discussion thread on Slashdot about the "ultimate mouse."
The article described a completely sealed mouse intended specifically
for "hardware-hazardous" environments.
I don't have a link for that, and I recall it being quite expensive.
There are likely less expensive alternatives to the mouse.
Furthermore, it's pretty common for shop floor automation to be driven
by touch pad screens, which makes mice irrelevant.
