Subject: Help with installing driver
Date: Thu, 21 Sep 2000 03:16:52 GMT
I've searched the linuxdoc.org website for help on this, but couldn't
find it. My cable connection doesn't work on Linux, so I'm hoping a
change in the network card driver will work. The old driver that came
with the OS is 3C59x.o, and the new one for the card is 3C90x.o The
card I use is a 3COM 900B-TPO...
So I downloaded the driver from the 3COM website, and tried to install
it. However, it says "this driver was built for" a certain older
version of the kernel, and that I must recompile. I recompile using
the directions that they give to me, but nothing happens.
I'm running Mandrake 7.0. Another thing I noticed is that I don't have
a lib/modules/2.2.16 folder, yet I do for the older versions of the
kernels I've used.
Thanks in advance

This should be fairly accurate.
A zombie process happens when a process forks
a child and forgets to kill it.
The OS can reclaim the zombie's memory but it
does claim one space on the process table.
There's (AFAIK) no way to get rid of the
zombie entry in the process table without rebooting.
The good news is you're not really out any resources
except a singe PID.
Ignore them, they dont matter.

most likely thing is that someone has trojaned your su, possibly just
replacing the binary with a different one. Either way, you had better
reinstall at least the basic packages if not the entire system...

Sounds like /etc/group is not availible. The system uses the info in
this file to turn UID's into names.

Is support for your card built into your kernel or is it loaded via a
module?
If it's a module, you want to add "alias eth0 <modulename>" to the file
/etc/modules.conf.
otherwise, hmmm........

The 1st thing audio players/recorders do when they start is
initialize /dev/audio || /dev/dsp for options like number
of bits per sample, sample rate, mono, stereo, etc using a
function called ioctl.
You prolly have a sound card thats not capable of true 16 bit
or something along those lines.

Groups can have passwords, too. Use the gpasswd command to set

www.rpm.org is of little use; the front page hasn't been modified in over a

Any help on what I need to do is appreciated.

Why is it ?. Apart from the obvious one of imcopatible monitors I see no
reason why you should not look at someone elses config file to see what
works for them. Newcomers sometimes don't want to be unix experts, they just
want a working system.

Do you have all the libraries? When I wanted to make a chrooted telnet
(I know, I know, just fun), I also had the same problem. Finally the
problem was that I didn't have /etc/nsswitch.conf and libnss_files*
This was a RH6.0 box. So, for me, it was a library issue. Maybe one
of your libraries is either damaged or more probably got erased.
Try a "strace -o strace_id id; more strace_id" command and see
which suspicious looking file/library is missing. If you can
have another strace output from a similar machine which doesn't
show the behaviour you have then just compare the strace_id files.

I'm trying to make a hard link from a directory in my home directory to
/mnt/robbo.
I have su'd to root, then given the command: ln -F /mnt/robbo
/home/robbo/documents. I get the error message "Invalid Cross Device
Link". I guess that means that it thinks /home/robbo/documnents is a
file. I have tried several other variants, and can't seem to figure this
one out. Yes, I realize that I could mount the drive to the location,
but I would rather do this.
Any thoughts?

Seems to be a typical DNS problem. Check the following:
When logged in the linux box, check your source IP by
questioning 'w' command. If you get a numerical IP address
that's the problem...
Linux tries to resolve your numerical source IP and does
not succeed - therefore you get the 1 minute timeout (about).
Solution:
- Configure reverse DNS for the source IP address by
setting it up in your /var/named configuration or simply
adding this ip to your /etc/hosts file.
