Half Open Syn Scanner

I'm looking for any sources related to Windows Half Open Syn scanning for learning. If anyone can make a simple one or provide one, i'd appreciate it. Thanks.

Check my reply to your PM

heh your syn flooder had a couple of errors in it and i did seem to fix them (compile errors) but overall it ended up crashing the program whenever run.

I am quite new to socket programming and i just wanted a simple source that worked so that i could understand what it was doing.

and strobe is for Linux unfortunately. Thats why i wanted you to code from that syn flooder you already made. heh I would REALLY appreciate it. Thanks.

*gasp* My code had compile errors *staggers backwards*.. I normally make it so clean that it won't even spit you a warning ! That said, if you have Windows XP SP2, it might bork my raw sockets.

What exactly were the compile errors you recieved and what did you do to resolve them. Lets see if I can get some time to write a skeleton syn scanner..

Yep strobe and other port scanners are for Linux, but they're written in C / C++ so it doesn't matter.. you can apply the same concepts.
Windows sockets and UNIX sockets programming are the same for all functions except where it starts with a capital letter.. or WSA..

Cheers,

pscan2.exe - 5 error(s), 5 warning(s)[/code:1]

I believe i just added (char*) before some of them and removed the set limit (such as [4096]) and used unsigned char*.
