Hi,

You need proper error handling. There are functions such as perror() and strerror() which can help in diagnosis. More information using the man pages:

Code:

man 3 perror

Or get the man pages online, if you're not on Linux.

I learnt network programming from scratch using https://beej.us/guide/bgnet/. There are good examples in there.

All the best.
