Just found this on my

mac

 hine - probably a standard 'nix thing.
And I prolly look like an idiot now that everyone knows that I didn't know about tcpdump 

Use like this:
tcpdump -s 0 -A -i en0 port 80

of course it's stdout, so you can > afile.txt. Not pretty, but helped me through a little nastiness today.

/p

Tcpdump is a good 'un. 

Learn

 ing  it's intricacies can be very helpful.

Another good one is ethereal but it's not installed by default most places.

=RT=

iptraf can also be very handy and on Windows let's not forget Wireshark.

BTW, sometimes it's good to substitiute -X for -A in the OP example, especially for protocols that are not text based (well duhh!).

Cheers,
td

[edit] I just checked and can't believe that I didn't include this in the favourite *nix commands thread, of well, so many commands..... [/edit]

I hear you TD, I am constantly looking stuff up 'cause I can't remember command names and options order.  *NIX is like going to a store where they have one of everything...you wander around inside trying to decide what to use.

Hope ya'll had a fun and enjoyable Thankgiving if you celebrate the holiday.
