Sockets

[JAB]

I wrote a small application via Socket programming that pings one of our network
servers using an IP address and the servers echo port (#7). I have a total
of 15 servers and only one is available through the echo port, the others
are using the ICMP protocol. The same routine that is running OK with the
echo port fails on the servers using ICMP.

Does anyone know how to ping a server that is configured using the ICMP protocol?

Thanks
JAB

Hi JAB,
I think u need to build up your own ICMP Datagram packet. PING uses
the ICMP Echo functionality. Check out
http://www.FreeSoft.org/CIE/Topics/81.htm

for a protocol overview. And

http://www.ee.siue.edu/~rwalden/netw.../icmpmess.html

for the format of the Echo packet which you'll need to build. You'll have
to create a Server Socket to receive the responses to the packets that you
send out.

Hope that helps.

Cheers
