Yes, but I've seen it quite often. The symptoms are you can't connect with
anything, rlogin, telnet or such programs; however the machine gladly replies
to ping.
I think the situation arises when an OS _has_ been running on the machine
and then crashes or hangs; in this state the ethernet card has been assigned
an IP address, and then it just answers any ping requests that comes its way,
without any intervention of the OS.
