[ILUG] Reading TCP data packet contents

[Ronan O Ciosoig]

Hi, 
I am trying to investigate the TCP transactions of a certain app on Mac OS X. I know you can use tcpdump to dump the packets, and use Ethereal or tcpshow to read the data, but neither of these are available on OS X. Any suggestions on how I sould go about it or apps I should use.

I am trying to reverse-engineer an app so I need to know all the transactions it makes if possible.
TIA.
