Help Please: Network Down
As of yesterday (April 24) my home network has stopped working. It WAS working the day before. I am running Sarge and I did do an upgrade. I don't remember seeing anything that I would expect to affect the network, but I also don't remember just what it did say was being upgraded.
I am no longer able to ssh between my two boxes.
Although my gateway box will dial in to my ISP if I access it directly, it does not pass anything on to my desktop box.
The gateway box is running Woody and has not been upgraded within the timeframe of this problem.
Has anyone else had this problem?
Any ideas on how to fix this will be appreciated. I am sending this from a Windows laptop and would like to get back to my desktop machine.
The error that I receive from ssh, /etc/hosts, and output from dmesg from my desktop box follow:
mns@xander:~$ ssh mareschal
