if I:

from computer "A" to computer "B" [B = 192.168.56.5] then I can set the SOCKS proxy for e.g.: Firefox to use "localhost:6000" on computer "A". Ok. I can surf the web through "B".

But:

• Can anyone sniff the traffic of "A"? [e.g.: computers on same subnet as

Sure, that possible if your name resolution traverses a network path interceptable by the guy sniffing.

You can tell firefox to use the socks proxy for DNS requests as well by typing about:config in the url bar and setting "network.proxy.socks_remote_dns" to true.
