Pete, under linux you can use "Hunt" too, it can do a lot of things, ie.
connection hijacking, arp poisoning, *lot* of sniffing, etc...
It doesn't support ssl or ssh.....yet.
You can find it here..

>From the site:
"The main goal of the HUNT project is to develop tool for exploiting
well known weaknesses in the TCP/IP protocol suite. I tried to implement
some "new" features which I didn't see in any free product. (connection
synchronization after attack, ARP relayer, ...)"
