It is likely to be your check-host-alive that the ping is called. On the default install from source, check-host-alive is check_ping. If the host you want to monitor doesn't allow pings, then I define chesk-host-alive2, and make check-host-alive2 use check_ssh instead. <BR>

You also have the option of making the check-host-alive command something that always returns a 0 exit code, like /bin/echo, but the downside of that is even when the host is down, it will still show as green on your map.<BR>

They don't send ping requests. At least not the ICMP_ECHO kind. If you're
watching the network traffic with a packet sniffer (such as Wireshark),
you could well be seeing Nagios' attempts at running the previously
configured ping check (or some such). Whatever it is, neither check_ssh
nor check_tcp have any knowledge if the ICMP protocol what so ever.
