I'm looking for a (win9x) program that I can use to monitor and log all data that comes over one specific port (in my case, I want to log all incoming and outgoing data on a local port... Anyone? It would be nice to send some raw data trought the program over the port as well, but that's additional... Please, I could use the help...
You want to monitor this, without the program itself being bound to the port? I think you want a packet-sniffer. You could probably filter the results to selectively look at data for a single port.
If you have Sygate personal firewall, you can make a rule so that it automatically captures packets under certain conditions.
If you want a more full-fledged sniffer, I would suggest Ethereal.
As for injecting your own data... Hmm. Are you sure you don't mean that you want a proxy?
What program or port are you trying to log? Could you give us more specifics?
Thanks Terr, this is just what I needed...
if you go to download.com, you can go around and search for packet sniffers that moniter all incoming traffic
finally a smart post, good job dfgt5
