[Lula] ssh just quit, now won't start

[Steve Glasser]

Hi gang,

I am in the process of deploying a samba PDC server for my lucky
employer.  It's a small shop with XP clients, a couple of macs and a few
network printers.

The o/s is debian sarge with the 2.6.8 kernel, all updates.  The
hardware is a "re-purposed" desktop with a big hd (ok, they're cheap).
Samba, cupsys, dhcp and dns are installed, also ssh (the deb--includes
server).  The idea is to run the machine headless.

Everything seemed normal until this afternoon when sshd quit and would
not re-start.  I have done apt-get --purge remove and apt-get install,
but sshd still refuses to start.  Tried rebooting--nothing.  

I am completely baffled.  Any help gladly accepted.  See below for more
info

Thanks, Steve
