[Techtalk] mysterious system halts - how to prevent/fix/detect?

[Julie Meloni]

M> Check your harddrive usage as well, to see if any of the disks are full.

We're good there:
Filesystem            Size  Used Avail Use% Mounted on
/dev/hda3              18G  2.1G   16G  12% /
/dev/hda1             7.3M  1.8M  5.1M  26% /boot


M> You may also want to poke around looking for a cracker, nmap scan the box,
M> see if anything weird is open and listening.

Now THAT I do all darn day.  That's the one thing I _am_ comfortable
doing. :)

Thanks,
Julie
