RedHat 7.2 !?!?!?
Did you compile a new kernel without providing for MS-DOS filesystem
compatibility? A kernel source tree downloaded from kernel.org does not
have that enabled by default.

i once tried vnc to connect to a unix box (i don't remember which
flavor). it's very easy, if u have the right to start the vnc-server on
the unix side. once u got that done, u give the vnc-client the ipadress
of your unixbox, and off u go.. then u can open as many xterms as u want
on the remote side...

Date: Sat, 26 May 2001 22:11:48 GMT
I've been monitoring my swap file, and it almost never gets over 5%
used.
I have 128 MB RAM and 250 MB swap file. That's a lot of unused HD space
I'd like to get back.
Is there a way to resize that partition and reapply the space to the
root partition? Or at least take a chunk of it as another partition?
Thanks for any assistance!!

I believe that irq 12 is the normal interrupt assigned to the
PS/2 mouse. Usually to solve the problem you have to change
the interrupt assigned to the other device.

I believe that RedHat stopped providing a rescue.img as early
as RH 6.1 or 6.2. They introduced a new method of doing rescue
using the installation CD. Unfortunately, they didn't include
very many tools for typical troubleshooting and fixing problems.
According to their documentation, they have much improved this
in the latest version in RH7.1. So you don't need a separate
"rescue" disk, the purpose of which is to run a system entirely
in memory using a ramdisk. You just use the installation media
with "linux rescue".
The boot floppy you make with mkbootdisk just provides a means
of booting from a floppy in case something goes wrong either
with lilo on the hard disk or if the kernel image on the hard disk
gets corrupted. But that won't help if for example the file
system on the disk is corrupted. In circumstances like that
you have to run independent of the disk from a ramdisk.
You can find other "resuce" or "root/boot" disks. A good one
is Tom's root boot disk, but that was a bit behind in the
kernel it provided the last time I looked, so it may not be
compaitiable with the system you have and hence may not be usable
to repair all problems.

Subject: Why ext2 filesystem check after some time?
Date: 27 May 2001 01:15:44 +0200
Every once in a while, the system tells me `mount count exceeded --
file system check forced' or something like this.
Why does it do that?
My thinking is: either the system is sure the filesystem is okay, then
why run fsck? Or the system isn't sure, then run fsck every time.
But why run it after 20 (or so) mounts?

have you since re-booted again? do you get the same symptoms again? the only
thing that comes to mind off the top of my head (if that isn't mixing
metaphors ;) is that your keyboard socket or some related part of the mobo
suffered some mysterious hardware failure between BIOS time and using it at
the console...
when you say it "doesn't work" I assume you mean there's no response to the
keyboard at all, right?

however, a binary is entirely different from a script in the way it's
executed. SUID scripts are not allowed by default (and for good reason) and
also you need _read_ permission to execute a script...

Well, if it's running a linux driver for the network card, you should
have the source. Recompile it for the new version of linux, and you
should be OK. You can also try peanut linux. That'w what I run on my
