Socket programming in C on Linux – tutorial

TCP/IP socket programming in C This is a quick tutorial on socket programming in c language on a Linux system. "Linux" because the code snippets shown over here will work only on a Linux system and not on Windows. The is called winsock and we shall go through it in another tutorial. Sockets are the "virtual" endpoints of any kind of ...

TCP Connect Port Scanner Source Code in C with Winsock
