Dear All,

I would like to know how to block the specific packets, so they will not be
captured by Ethereal. Would anybody let me know what filter expression that
I can use to :
1. Block the broadcast packets
2. Block a specific protocol, such as IGMP or ARP

Thanks a lot in advance.


In ethereal, you can use "not" to exclude something.

Here's an example from the ehtereal help.

"Examples combined: capture all traffic to and from 192.168.0.10 except http

host 192.168.0.10 and not tcp port 80"
