Today, I found upd.pl in my tmp directory. The date was oct 09. I also found my /etc/passwd and /etc/shadow had been changed

SSH is not
running so I don't know how this happened.
Perhaps your system is not as simple as you think it is. ;-/

Thanks, Keith!
Guess I'd better brush up on my vi commands in case I have to boot from a rescue disk. :-)
All you need is [Esc]q! :)
Just guessing here, but to do this, I need to add:
tmpfs /tmp tmpfs size=100M,mode=0755 0 0 To my /etc/fstb and cross my fingers?
I would make it a little bigger as 100M depending on how much memory you have. And the mode should be the same as /tmp would normally be => mode=777 :)
If you have been hacked, like it seams you have, you should first find out how the guy got in. Do you have a webserver running? Firewall enabled? Then just to be safe I would always reinstall as you never know what he might have done.
Then you can modify the tmp in fstab
