If you hit control-alt-F1 (or F2 or ... all the way to F6) do you see
anything?

 

What happens on the monitor while you boot?

 

I've seen cases (personally) where an install decides the monitor can do
more than it can (and I think I had an upgrade do that once also),
leaving you with a dead monitor.

 

However, given that you cannot ssh into it I'll bet that won't be the
case - but hopefully you can see something on the monitor as it boots...

Mike,

 

Unfortunately, there is still no signal after a hard reboot. If there
were, then I would do what you suggest. 

 

Any ideas on how I can determine what is wrong by using something like a
knoppix cd?

From there you'll need to figure out if the boot loader is intact or
not. If it is you can boot into single user mode and try to figure out
what's going on with the box. If you do not get the boot loader now
we're talking about a repair to either the loader or the system as a
whole using a disc or memory stick.

	I used aptitude to upgrade a headless server from Debian stable
to Debian testing. The upgrade did not generate any error messages, but
when I rebooted I could not ssh into the box (connection refused) nor do
I get any output on a monitor I attached to the box (no signal). Apache
does not appear to be running either on the box (could not connect to
the box). I can successfully ping the box.

appreciated!

	 

	Thanks,
