Thanks for the pointers Nick. I'll keep exploring and report back any success.


further: i realised where i could find a working debian box to ssh into
and report that my wireless debian access point at home does not have a
route for 127.0.0.0, but all other networking still works. therefore
this appears to be a red herring.

same situation with horse (shell.clug.org.nz)

however both boxes have the destination entry in the 192.168 part of the 
routing table ending in a 0 - ie the network address.

Take a good hard look at /etc/network/interfaces - posting a copy might
be a good idea.

This is from my mail server... debian sarge - not too up to date. About as simple as you can get. As for firewalls, just switch them off until you know things work!
