Can you post /etc/hosts and confirm that it begins like this:
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1       localhost.localdomain   localhost

Can you run
ping localhost
(from a terminal session), leave it for five seconds, press Ctrl-C

Thanks,
James.
