There ain't no "almost" to it; tcpdump is the world's most widely-used
bargain-basement, no-frills-but-boy-does-it-get-the-job-done sniffer.
I used it to scare a hacker so bad he started crying, once. Caught him
warning the guy who he'd given his password to, then let *THAT* guy think
our customer had rolled over on him. Scared the bejeezus out of both of
them. :-)
All it took was a few minutes monitoring his IRC traffic with tcpdump.
Also used it to prove to one of our (not this job, last job) system
operators that telnet wasn't secure. When I told him which of his ex
girlfriends' names he'd used as his password, he turned white as a sheet.
:-)
BTW, keep all of this in mind when letting unencrypted traffic pass through
your friendly neighborhood ISP.

Subject: tcpdump usage
Can someone repost the tcpdump command that almost makes the linux
box a sniffer?
