Pinging won't accomplish anything if you're trying to see if
your network card ( in Pete's case) is working.

Whether you have a connection to the outside world, you should be able to
ping since it's the loopback.

If you have one or more ethernet cards, you should be able to ping the IP
address of your card.

If you have a dialup connection, you should be able to ping the PPP

These are all ways to ping your computer because all these IP addresses
belong to your computer.

Pinging does not go to the NIC.


PS: BTW, Peter -- I don't think pinging goes out then
comes back -- just see traceroute.  But if you have the system configured
to filter out all ICMP packets (via ipchains or whatnot) then you
wouldn't be able to ping your own network card, or so I'd think.
