Craig,

	Could I bother you for a little more information?  You say

    "Looking at one of the CSNET machines, I discovered that out of 170,000
	IP packets received, ... "

	By CSNET machine, you mean host, rather than gateway, right?
	
	How recently did you notice this occurrence and can you give a historical
perspective to this problem (not noticed/not looked for a week/month ago)?

	Is it possible to find out where some of these ICMP messages are coming
from and what the contents of some of these messages might be?

	I ask these questions because I want to see if it is, perhaps,
our gateways that are, say, sending out an incorrect ICMP message in
response to some problem (ttl expire, redirect, whatever).

	Thank you.

robb.
