IPChains question (SOLVED)

This was a very timely discussion.  Unfortunately, not quite timely
enough to prevent me from almost hanging my server.  I ssh'd from my
laptop to my office's Linux server.  I changed something trivial in my
backup script, and ran it to make sure it was o.k.  It started runnning,
but a half hour or so later, people started having problems mounting
Samba shares, DNS stopped working, etc.  So I sat down at the server
console, and I couldn't even log in.  Couldn't use ssh to get in
either.  I was contemplating hitting the power switch (ouch), but tried
turning off the tape drive first.  Presto.  Everything came back.
