Evidently I'm really missing the boat. I've been trying to find the well-known port for ICMP. Is there no such thing?
You're right; you are missing the boat. Ports only apply to UDP and TCP. ICMP does not run over UDP or TCP, it runs straight under IP, which means that it has an IP protocol number. ICMP is protocol number 1 TCP is protocol number 6 UDP is protocol number 17 -- Mikael Olsson, EnterNet Sweden AB, Box 393, S-891 28 ÖRNSKÖLDSVIK Phone: +46-(0)660-105 50 Fax: +46-(0)660-122 50 WWW: http://www.enternet.se E-mail: mikael.olsson () enternet se
