Can anyone give me some pointers about how to access ICMP under Ultrix/4.2BSD ? I'm trying to write a program to listen for ICMP messages and gather statistics about them. I have been able to get Echo Reply messages, but I haven't been able to get Echo Request, Host/Network unreachable, or routing redirects. --Pat.

In order to play around with ICMP messages on 4.2/Ultrix you need to add fixed up RAW_ICMP protocol code and then the user code is a fairly simple matter. The code is in 4.3 or if you want you can get new drivers for 4.2 from BRL-VGR via anonymous FTP and load the file arch/ping.shar or arch/ping.tar -Ron
