Question

i want to start serious programming in C. i am thinking of starting with some simple console application used for network security or pen testing ... pls suggest me some, and as i am new to it , i would like to have its source code so that i can read and understand it in a better way

Answer 1

well you can find open source security related tools at http://www.sourceforge.net
for network security i think nmap is a very important tool and it is an open source software so you can get its source also , nmap is just an example as it is one of the most important tool.

Answer 2

well here i give the code of a project when i saw networking, its a simple web proxy (doesnt work with encode and frames and maybe other things, and its a client and a server) writed in C (its for linux, won work on windows), it can handle several clients by using process, i dont remember the arguments or how to run it u can guess by reading the code or the statement (its in the zip), its in spanish also. Hope it works for u.
