AURGH!! (@jdd, that hurt, you know.)
"ICMP" is another protocols, for which are
no sub-ports are defined.
so what mean the line above from /etc/services?
The file /etc/services is only relevant for the TCP
and UDP protocols!
then what is icmpd? is it at all related to icmp?
please I only need a small answer
and, for James, of course the wikipedia page was my first read, but

I only use icmp for ping and asking is a computer is dead or alive...
So I guess there is no way to ping a computer that lives after a gateway?
