Howdy there, if you are trying to use sockets it is a lot easier under a unix/linux OS rather than a Windows based one. So with that in mind... if you want to build your own i'd suggest reading up this guide : Beej's Guide to Network Programming Using Internet Sockets
It's a great starter guide.
Otherwise look for tools on the web, there are a couple around for most OSes i think. Not 100% sure about windows though (depends on if you have sp2 i think, which i would hope/pray you did). Note.... these tools should not be abused and only used for testing purposes only. Either way it would pay to read the tutorial for a bit of brain food! Hope this has helped
