Have you got a sniffer to trace the error ?
It would be interesting to see the packet in question
since ICMP has 20 ish different error codes.
The ICMP error should not be broadcast either, it

Thanks for your answers. Ill report these ideas to my customer and wait for
his response.

I have a client that installed a Linux NIS server which is working with
broadcasts. That server is connected to cisco 4908. Se
RFC 1256 looks interesting.

This document specifies an extension of the
Internet Control Message
Protocol (ICMP) to enable hosts attached to
multicast or broadcast
networks to discover the IP addresses of their

The ICMP error should not be broadcast either, it
should be unicast back to the originator of the
erroring device. Off the top of my head I cannot think
Hi All,
I have a client that installed a Linux NIS server which is working with
broadcasts. That server is connected to cisco 4908. Server IP is
192.168.5.2. He is saying that when NIS server starts to work all clients
and NIS server is receiving a message at below,
