I was able to help via Team Viewer.
The FOG server’s IP address changed. The server is probably set to receive DHCP and maybe the reservation was deleted or something - not sure. It had a very weird IP, not one you’d normally set as static or as a reservation.
Also - Connie has fog 0.29 installed on Ubuntu 10.04
The root partition has around 30-40GB of free space now - but it will surely run out of space again.
Images and DB need backed up, and a new server needs built, honestly.
