We are having some network trouble with an iris 2400Turbo. It is running version GL2-3.5 of sgi's unix, with tcp/ip. Apparently it is responding to routing packets with a "port unreachable" ICMP reply. My understanding is that it should just be ignoring them. Has anyone seen this before?

RIP/UDP? If so, is routed(1M) running? I seem to recall a bug which would cause routed to quite. I don't remember if it was fixed before or after 3.6. Of course, corruption of files such as /etc/services and /etc/rc.tcp, or a crazy YP master could make it difficult or impossible for routed(1M) to run. In any case, you really should consider upgrading to 3.6. My understanding of the universe and everything implies one should not ignore ordinary UDP packets. One hopes and expects that you are not seeing port-unreachables for ICMP-redirects. If you are using some other kind of routing, with a deamon that is supposed to be listen on some port other than 520, then you'll have to do some porting. Vernon Schryver Silicon Graphics vjs@sgi.com
