An example project for network-programming written in C/C++

Question

Are there good open-source projects on P2P file-sharing systems or distributed file systems written in C/C++ ？

I need a project to start with network-programming.

Can anyone give me any suggestions?

Answer 1

Boost asio examples on the boost.org are really good one to start.
