Strange behavior

[Paul Schmehl]

What would cause this?

ping localhost
PING localhost (127.0.0.1): 56 data bytes
ping: sendto: Can't assign requested address
ping: sendto: Can't assign requested address

Yet I can ssh to localhost.

ssh pauls at localhost

There's no firewall enabled.

The system is listening on various ports.
