Jerry,

        Have him show it to you. A lot of DBAs consider ping to be a test of
connectivity to a database, so it's really a layer 6/7 thing. If the
database server is busy, it may take a little while. 80 seconds sounds kind
of fishy though. ICMP uses TTL like any other IP packet, so packets won't
loop forever. Put a sniffer on there and verify what he's telling you.

Hello group,

                 I had a "genius" who dabbles in his own network code say
that his Ping response time from client to his server, which is only 3
routers away, was over 80 seconds. At first I thought he meant milliseconds
but it actually turned out to be 1 minute and 20 seconds.

Question #1.) Does anyone know the timeout maximum from the ICMP spec? I
tried looking up in the RFC but was unable to find it.

Any extraneous comments welcome.

Jerry
