U could use something like dsniff.. it allows you to do
arp spoofing and such..
Dario is correct.. this could cause strange things to happen if utilization is
to much for your host to keep up with..
But (always a but) it is good to know these kind of tricks if you are in a tight spot..

Simone:
what is 'a whole switched network' ? Does that mean to connect ethereal to a switch port & sniff traffic from another switch? if that is so, you will need something like Cisco's RSPAN
with regards to APR: APR is not a protocol, but a trick - an interesting & cunning trick, but which shouldn't be used as 'the' method to sniff on a switch - it can produce unpredictable results on end hosts, overload the machine doing the sniffing, and cause network outages.
Try to use the standard procedure to sniff on a switch (monitoring traffic to a monitor port). Only if your switch does NOT support this feature I would use something like APR - which is not supported on ethereal

I would like if the just released 0.10.9 version is aware of the APR protocol like http://www.oxid.it/ca25um/topics/sniffer.htm in roder to handle also networks with switches instead of hubs.
