Note that ping (more properly called "ICMP echo"--"ping" is the name
of the program itself) uses the ICMP protocol (separate from TCP or UDP)
and ICMP doesn't use ports.
I should have said:
--"ping" is the name of the _client_ program itself)
The server end of "ping" is usually built into the protocol stack
itself or in the superserver (xinetd in newer Linux implementations).
