Hi All, Why some you have said that ICMP packets should not be broadcasted?. I mean, many people ping the broadcast address to know which hosts are working. Right?, this kind of ping does not work on Windows systems, but in Unix does.

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 should be unicast back to the originator of the erroring device. Off the top of my head I cannot think of a purpose for b/cast ICMP. I'll have a dig around in the RFC to confirm. Phil. --- Cisco Breaker wrote: > Hi All, > > I have a client that installed a Linux NIS server > which is working with > broadcasts.
