I found myself wondering the same thing after I dumped a 10 minute
capture on our network, it ended up being around 3 gigs worth of data
and I wanted to find out exactly what was plain text. After much
googling I found a plug in (which I could never get to work I might
add) for Dsniff that does just that, it runs through a Pcap file. Link
to the patch is found here: http://www.sephail.net/patches/dsniff/
Here is another method (again this didn't work for me either)
http://seclists.org/lists/pen-test/2001/Jul/0070.html
I never was able to get this to work (short of replaying the session
on a hub, which DID work)
But I think a program that does this would be a great thing to run
agaist my 20gigs of Pcap files I have sitting around.
