I can do that, but that only logs what's going on. I must have the content of those packets.

Can you do a `tcpdump > file`?

anyways, there is a program called sniffit (check http://www.freshmeat.net) which can view packets in real time or dump them into a file. It has allot of options and it is just want you are looking for. Don't abuse it : )

Hi,

I'm looking for a tool to capture network traffic (specifically port 23) in a file, to be able to 'play' them back like a movie. The capturing would have to be done including a timestamp, or else the playback would be way too fast.

I know I can see what's going on with tcpdump, but I can't see the contents. And if I see it, how can I play it back?

Can anyone help me with that? I really have to see what other people are doing to my systems. I'm getting kinda desperate..

TIA,

Rogier Maas

Thanks, I saw the website, it looks great. Now see if it can display the packets in a way I can see what the hacker sees like WHSIWYG (What He Sees Is What You Get). Rogier Sean Groarke wrote:

Forgive me if someone has already mentioned this and it slipped past me: Try ethereal (which is not, as it's name might imply, only usable on ethernet!) which is a professional-level Sniffer/Net XRay clone.

http://ethereal.zing.org

It is a seriously good network sniffer, with neat features like being able to pick out and reassemble the data content of an entire TCP stream with one mouse click, colour data streams based on filters, read and manipulate true Sniffer files, etc.. I use it daily in a work/lab environment, and would strongly recommend it. I think there's also a version of it on SuSE dist (can't remember) but the web-site has some recently updated versions. Oh, and it *is * GNU GPL!!
