The 'L' error is indicative of either a media failure or a geometry
mismatch. Since your boot floppy works it must be a mismatch.
The first stage boot loader has been loaded and started, but it can't
locate the second stage boot loader (/boot/boot.b). The two digit error
code indicates the type of problem, if the code is visible.
You might want to try the 'linear' option in lilo.conf. Just put it in the
general region.
You also might try installing LILO onto the MBR of the boot disk.
Or, you could use the
disk = <device file> (/dev/sda)
bios = <bios device number> (0x80 - first bios disk)
cylinder = <amount>
heads = <amount>
sectors = <amount>

You can put it into the background with (in bash) ctrl-Z, then bg, but it
will be killed when you log out because all your processes will get a
hangup signal (SIGHUP) at that time. If you really want something to
keep running after you log out, you generally have to set this up before
you start it, like using "nohup" (see man nohup) or "at".

had same problem several times... seems related
somehow to BIOS; haven't found a fixed rule to get rid of it.
But it's not clear to me your cfg: guess you had
boot=/dev/hda
root=/dev/hda1
then you switched to
boot=/dev/hda
root=/dev/hdb1
right?
can you xchange hda/b? can you have BIOS boot from hdb?
then
boot=/dev/hdb
root=/dev/hdb1
might work.
but try also to run lilo from/on new hd _without_ old hd, from a
rescue (fd0) boot.
and... you made bootable hdb1, right?

at will do that. Also read the *sh man page regarding fg and bg if you use a shell

I've seen (and used) two diffrent types of KVMs - passive (basically just a
switch) and active (switch plus keyboard, mouse, and monitor simulators). A
passive KVM that I have used in the past worked well with Windows but had
problems with Linux. The active KVM that I use now (Edimax Genie) works
fine with both (Linux is using IMPS/2, BTW). I've noted though that it
works much more reliably when the mouse is completely still when actually
switching.

Well, it looks like http://www.pathname.com/fhs is back up. Another WHOIS
check shows that the record now expires in 2001. Apparently the check was
delayed in the mail.
In any case, here is what it has to say about /opt:
/opt is reserved for the installation of add-on application software
packages.
-snip-
BEGIN RATIONALE
The use of /opt for add-on software is a well-established practice in the
UNIX community. The System V Application Binary Interface [AT&T 1990], based
on the System V Interface Definition (Third Edition), provides for an /opt
structure very similar to the one defined here. The Intel Binary
Compatibility Standard v.2 (iBCS2) also provides a similar structure for
/opt. Generally,all data required to support a package on a system should be
present within /opt/<package>,including files intended to be copied into
/etc/opt/<package> and /var/opt/<package> as well as reserved directories in
/opt. The minor restrictions on distributions using /opt are necessary
because conflicts are possible between distribution-installed and
locally-installed software, especially in the case of fixed pathnames found
in some binary software.

We are running a secondary DNS service on a Linux Red hat 6.2 OS
We had no problems initially but then we stopped getting authoritative
responses from this machine.
A colleague went into /etc/ and typed named and then all was fine.
Now twice this week we have not been getting an authoritative response from
the box, so we go into /etc/ and type named and nothing happens... apart
from the cursor dropping down a line and just flashing (without a prompt)
typing ps shows nothing to do with named.
Is it not running?
If not then why?
If not then how do we stop it from stopping?

tar doesn't mess with the case of filenames and certainly not with the
contents of files, so whatever is on your source CD will be what winds up on
your hard drive. How did you mount this CD? As -t iso9660?

If that is how it is on the CD, how does it work there?

In one of the threads, from washington state, a 60 server area net was
converted from DB2 to mySQL adn Linux. They mention the stability in a
production environment, with at least one linux server staying up 425 days,
which is every day since they installed it. Read some of the other threads
too.

If it is the same kernel running on the same kind of machine, no.
I've been running Linux for 3.5 years. My box has a 24.7 connection to the
internet and I only shutdown for hardware changes or fixes, or because a
lightning storm is over head. I've been using SuSE for 3 of those years
and RH before that. The linux kernel in my box has never crashed. Some
apps have crashed, but the kernel never has.
Before I had RH on this box I was running Win95. In fact, I had purchased
this box NEW on Dec 27, 1996. By March 7th, 1997 I had to reinstall Win95
FIVE times. Even Sony's 'medi-kit' was of little value in keeping the os
stable. I installed RH 5.0 on March 7th. The crashing ceased.

The other major alternative would be to use NTP, findable at
<http://www.ntp.org/>, which provides a protocol to manage
synchronization, taking into consideration the speed of propagation of
time signals across the Internet.

Curiously, Linux isn't responsible for this. It merely stores the
present time in UTC form in all sorts of places.
Instead, GLIBC is responsible for _displaying_ the time for you.

I've been trying to find a linux-compatible parallel ethernet adapter.
Since I recently got an older 486 laptop with no PCMCIA slots. I read
that a Xircom pocket ethernet will not work. Pretty much the only places
I know where to look are Ebay and Pricewatch.com.
Ebay has mostly Xircoms, but there is one Kingston that I found. Is a
Kingston poket ethernet parallel adapter compatible with Linux? I
haven't found any specific information about it, but I supposed it's
possible Kingston just used another company's chip in it.
Failing that, does anyone know WHERE to buy a Linux-compatible parallel
port ethernet adapter? I know pretty much what I need to buy, I just
need someone to point me to someone that sells one.
I'd like to buy one of the recommended Accton or DLINK ones, but they
are not to be found (at least where I'm looking).
Thanks,

Those are mostly ansi escape sequences. They are interpreted
