RE: Ping to a specific port

Just curious:
I'm pretty sure that there is a way to setup a server/router to not
reply to ping.  How can this be done if PING is a internal function of
ip?

Sorry, this isn't true.  PING doesn't use the "echo" service.  PING is
an internal function of the ICMP (Internet Control Message Protocol).
You send an ICMP echo packet (or, more correctly, "datagram") and it
sends back an echo reply.  This is built into the core of the IP stack.
