icmp problem

[Kevin Darcy]

I'm sure named isn't sending ICMP packets deliberately. I consider it far
more likely that named's UDP packets are somehow triggering the networking
code in HP-UX to generate the ICMP packets, although offhand I can't imagine
how or why. Can you look at the ICMP packets to see what kind they are (echo
request/reply, source quench, redirect, timestamp or whatever)? Maybe there's
some configuration setting in HP-UX that would turn them off.
