I would be quite suspicious of this situation.

It would appear that someone has taken this box and brought it down to run level 1 or 2.

I'd think maybe an internal disk failed, but those L class boxes generally ship with one or two disks, so there'd be no system if the disk went. I generally mirror from one disk to another.

So the question is, who had access and what did they do?

I have seen NIC failures that work like this. The card is alive but will only answer ping.

Diagnostic steps:

1) get on the console and run who -r what is the run level.

2) ps -ef | grep ssh see if secure shell is still running.

3) dmesg look for hardware problems related to the NIC.

4) Reboot the system, shutdown -ry now its not doing anything useful anyway.

It looks like you have networking problems. Have you checked your router or switch and make sure it is OK?
