well let me be honest it was not a hacking LAN it was more of a gaming lan set up by 4 computer game crazy kids(including me).but i am also using that LAN to increase y computer security knowledge trying out a few exploits and coding my own exploits and using them like the WebDAV exploit using a rebind shell on port 80.It was really fun.
but i had a few problems too say i want to code a exploit for a application(or server)that runs on port 4040.that server is costly 500$ so i can't buy it i am trying to make a dummy server that will run on same port 4040 and accept a string from user store it in a buffer 46500 bytes long just as the server i am trying to exploit does.
so it will crash on anything valid request above 46500.
i have been able to send a valid request to the dummy server and crash it but as i was trying to bind it to the same port after service crash( rebind shell code of port 4040
http://www.scan-associates.net/papers/one-way.zip )it didn't work the origional server runs as a system program by default after installation i just wanted to confirm if it a requirement to exploitation that the software i am exploiting be a system program if yes how can i make my dummy server a system application?
