Once, I had the same problem too, but I had a NIC and a PPP connections.
The problem was due to the DNS server that couldn't be found; in
/etc/resolv.conf, usually you have:
nameserver a_dns_server
If the a_dns_server can't be found (or is not up during the lookup),
telnetting to the server would take a long time.
My mail server, which is a dial-up client, doesn't have any references to
outside dns servers. It's a bit unfortunate, but since telnetting is
faster...
