Hi!

Since I like to do my homework (sort of research),
I looked at the tcpdump man page in order to figure
out how to filter what Andreas said:

> Filter out all traffic NOT going to/from the endpoints (and servers like 
> gatekeepers) using a capture filter. 
> ip hst 192.168.11.4 or ip hst 192.168.11.5 or ip hst 192.168.11.1
> Or something like that, creating capture filters is not my hobby ;-)
> A couple of more suggestions:
> - Filter out all non tcp or udp traffic 
> - filter out all non ethernet traffic

But I couldn't get it right... would you be so kind to enlighten me?
As always, thanks in advance,
Hector
