About 10 months ago, i set up a server for myself. I put it in the basement and let it chug along nicely with nothing attached to it but the powercord and ethernet cord. I would admin over ssh and sftp. occasionaly i rebooted the machine.
now this week i came home from a weekend away and i cannot connect to my website. odd.
...try to ssh to server - cannot connect.

...reboot at the physical switch - still cannot connect
so then i set the conputer up with a monitor and keyboard to investigate. On the server its self, everthing seems to be working fine*. httpd vsftpd and sshd are running without complaint.
I used elinks to load up my webpage (via a "localhost" address as well as an internal IP ( 192.168.0.73 ) address ) and that worked aok. yet when i walk across the hall to my workstation and connect via the internal IP ( 192.168.0.73 ) The connection times out.
simmilarly any access via my domain name gets a time out as well. connecting to ssh and sftp also fail.
-- help, what is going on?
*there was a problem with sendmail hanging on serice initialization, but i disabled sendmail, and it seemed to be irrelevent anyways.
