No point. The shop was in another city and have since then ceased to
trade. I have had the Slicom card a few years (as I stated) and I had
just transferred it from the old laptop to my new one only to find
that DOS and Windows drivers were the only ones on the disk. Not much
use when you are changing OS to FreeBSD.

No need to abandon kmail just because you want to run the Gnome desktop.
It will run from there nicely. Also from fvwm2, AfterStep, etc.

You might also want to look into using SGI's XFS.

An ISO install image is available which will work with RedHat-7.1. Using
it here but can't tell you anything about large file support. It is
absolutely stable and after a power outage rebooted with no problems or
delays.

Subject: /bin/login cannot be removed
Date: 9 Jun 2001 19:05:57 -0700
Linux Gurus,
Please help.
After I upgraded my system from RH 6.2 to RH 7.1, I found
that the login command is no longer working. I can't login
from the console as root or as other users.
Then I noticed that the /bin/login has not been updated
during the upgrade. When I tried to upgrade the util-linux
package, it fails because /bin/login cannot be renamed
or removed. I tried different methods (including boot the
system in rescue mode) and yet I can't remove the /bin/login
executable.
# rm /bin/login
rm: remove write-protected file `/bin/login'? y
rm: cannot unlink `/bin/login': Operation not permitted
# mv /bin/login /bin/login.org
mv: cannot unlink `/bin/login': Operation not permitted
mv: cannot remove `/bin/login': Operation not permitted
I suspect that my system was hacked with a bad /bin/login.
Anyway, how can I removed this file under ext2? I really
don't want to reformat my drive if possible...
thanks,
Dowson

Very likely your computer *can* boot from cd, but the bios setting for
boot order is not set to do so. Most computers, right after turned on,
allow bios access via some special key like DEL or F9. Often during
memory check there is some note saying "hit such and such key for bios
setup". Somewhere is a boot order, and a floppy and IDE are usually
listed, sometimes CD. You will need to tell it to boot CD prior to hard
drive. The actual wording and location in bios is very dependent on the
exact hardware, so you're on your own to be very observant about the
first messages on startup to see how to get to bios setup.

Maybe the attribute of /bin/login is set so it cannot be modified. See:
man lsattr
man chattr

Subject: ARP proxy - help needed
Date: Sat, 09 Jun 2001 21:25:49 -0400
Hi!
I am trying to add a proxy ARP entry for 1 IP address on Red Hat 6.2.
What I am doing is working, but the problem is, once I reboot the box
all the static entries from ARP cache disappear. I'm guessing I need to
add the arp commands to a script, but which one should I use? This is
probably a dumb question, but I'm relatively new to linux and have not
had much experience with modifying the startup environment :(
I'll describe what I'm doing in a little more details.
There are 2 interfaces on the linux box. For the sake of an argument,
the address IP address of eth1 is 192.168.10.100. I need to set up an
ARP proxy on that interface for 192.168.10.12.
I am doing this:
"arp -v -i eth1 -Ds 192.168.10.12 eth1"
"arp -v -i eth1 -Ds 192.168.10.12 eth1 pub"
Issuing "arp" after that returnes this ( I put xxx for obvious reasons):
209.208.183.1 ether xxx:D3:9D:E3 C
eth1
10.10.10.12 ether xxx:D6:32:2B C eth0
192.168.10.12 ether xxx:D4:8D:81 CM eth1
192.168.10.12 * * MP
eth1
This works fine for me, with the exception that I can't figure out how
to make the arp cache entries permanent so they stay this way every time
I boot up.
Help would be greatly appreciated!
Thanx in advance,
Stan

I would like to install Linux on old machines, so I'm looking for a
distribution not larger than about 50Mbytes.
I would like to have X included and if possible, easy to install from
scratch (not from another OS).
At present I've looked on linuxlinks.com and at Micronix. The Micronix
webpage doesn't work very well, so I'm having problems downloading (but it
needs to install from DOS anyway).

If you are running RedHat or Mandrake or similar, append your commands to
/etc/rc.d/rc.local.
Come to think of it, that will work with Slackware, too.

chattr -i /bin/login -- beware though, as the util-linux login
binary may not the one you want. Are you sure it is compatible
with RH's version ( shadow / PAM / ... ) ?

I've done a chattr +i on quite some binaries, all in /sbin
for instance and all the shared libraries. Can help to avoid
a "Oh shhhhhhit" following a rm * as root in the wrong
directory.
Hope it helps, but be careful,

...well, you know, there's a freeze, and there's a Freeze. When the
system freezes up, what do you do? Can you Ctrl-Alt-Backspace to kill X
and restart it? If so, then there's a problem with X that is getting
triggered occasionally. If that doesn't work, can you telnet in from
another machine and kill X, making the problem go away? If that works,
then you have a slightly more serious problem with X. If neither of
those work, can you use Alt-SysRq-S then Alt-SysRq-U then Alt-SysRq-B to
reboot the system in a partially sane manner? If you have tried all
these, and you have to cycle power to get the system usable, there is
either a hardware problem or a serious kernel-level problem.
Are there any bread crumbs left in /var/log/messages when you have
restored the system to a usable state? Also, more information about
your system would be helpful. Which chipset, are you overclocking,
which graphics card, etcetera.
>I also want to know how to login to plain text screen instead of
>graphical GNOME desktop (and vice versa). Thank you in advance.
Press Ctrl-Alt-FX (where X is from 1 to 6) to get to virtual consoles 1
through 6, where you should find a console login being managed by
mingetty. The graphical login display resides on virtual console 7 by
convention, so Ctrl-Alt-F7 to go there. You can switch between/among
them at any time.
If you don't want to start X at boot time, boot the system with "linux
3" and the system will enter runlevel 3, which is the same as the
"normal" runlevel 5, except that X is not started. You can edit
/etc/inittab to change the default runlevel, and you can also enter
"init 3" as root to switch to runlevel 3.
