Help: Wierd networking problem

[Roger So <rogerso@sis.dhs.org>]

Hi all,

My machine was running fine until I had to reboot because it had to be
physically moved.  After that I'm having some wierd problems:

- ping and traceroute from the machine doesn't work, although ping and
  traceroute to it does.

- running ip (from the iproute package) produces the error message:
  Cannot open netlink socket: Protocol not supported

Everything else though runs fine.

It's running kernel 2.2.11, and most packages are from potato.

Thanks

Roger So
