I got:

Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
...

I guess it's working:) I would have done a simple test
like this myself if i had more experience, but i've only
had debian installed for a few days. I last installed and
used mandrake a couple of years ago, which was set up using
'older' methods. Is ifupdown specific to debian, or do other
distros have it too?
