failed to connect to localhost

[Patrick Hsieh <pahud@pahud.net>]

Hello list,

I have a Debian 2.2r4 running 2.4.16. Everything is fine, but I fail to
connect to localhost.

Then network configuration is ok, since it can communicate to the
internet. But when I type:

ethome:~# telnet localhost 25
Trying 127.0.0.1...

The connection hangs for a while, but I am sure the smtp daemon is ok
because incoming connections are alive.

This problem exists on all localhost connections. This is weird because
I DO have a lo device:

ethome:~# ifconfig lo
lo        Link encap:Local Loopback
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:12 errors:0 dropped:0 overruns:0 frame:0
          TX packets:12 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:3936 (3.8 Kb)  TX bytes:3936 (3.8 Kb)



ideas?
