Re: Etherape filtering is not working

[Michael Miller <mike.mikemiller () gmail com>]

Did you look at the FAQ and see the following?

Is it possible to see just traffic within my network? Is it possible
to see just traffic to/from the internet?
You can indeed filter traffic. Have a look at the filter entry in
preferences->capture->filter
Suppose your network address starts with 213.227
If you only want to see traffic within your network, then the proper syntax is
ip and src net 213.227 and dst net 213.227
Or if you want to see connections to/from outside your network then
try something like
ip and ((not src net 213.227) and dst net 213.227) or (src net 213.227
and (not dst net 213.227))
Filtering is done by libpcap. For the full filter syntax, see the
pcap-filter man page or the tcpdump web site http://www.tcpdump.org/
