Socket programming
Literature
If you are completely new to socket programming, have a look at this tutorial. It explains socket programming step-by-step with code examples that a easily be compiled and run on your computer.
Troubleshooting
If you run in a situation where your TCP/ IP socket code compiles and runs, but from time to time a connection is lost for no obvious reasons or, for instance, if your application keeps too many, no longer used, open sockets, one good idea is to check the TCP state diagram first, and review your code accordingly.
