What do you mean exactly, Brian ? Tcpdump (and similar programs) of course
allows its user to see anything passing by on a net (which is why nothing
confidential should go on any net unenecrypted). Tcpdump can only be run by
root, so if you can't trust yourself . . . .

Interesting thought - tcpdump is on the BBC - access to a workstation, 5
minutes, and you're viewing everything on a company's LAN :-). I'm not
familiar with what's out there but I'm sure there are tcpdump type programs
available for Windows also. Thankfully for corporate security, this becomes
much less of an issue (none at all ?) on a switched LAN.

Niall
