A great TCP/IP capture utility
I was writing a program the other day that would talk to a web server. It wasn't working, and I couldn't figure out why, because the particular technology I was using gave me very little to work with in the way of, oh, I dunno, OUTPUT??
Well, that's a rant for later. But what I ended up finding, and solving the problem with, is a great little program called SmartSniff. SmartSniff allows you to capture TCP/IP packets that pass through your network adapter, and view the captured data as sequence of conversations between clients and servers. Once I started it up, I could monitor what my program was saying to the web server and I immediately saw where I'd gone wrong. The problem was easy to fix. This will also be good for times when I need to write a program to "mimic" some other application.
The best part about SmartSniff is that it works really well. The second best part about SmartSniff is that it's freeware
