* How come I get "address already in use" from bind()?
* Why don't my sockets close?
* How can I make my server a daemon?
* How can I listen on more than one port at a time?
* What exactly does SO_REUSEADDR do?
* What exactly does SO_LINGER do?
* What exactly does SO_KEEPALIVE do?
* How can I bind() to a port number < 1024?
* How do I get my server to find out the client's address / hostname?
* How should I choose a port number for my server?
* What is the difference between SO_REUSEADDR and SO_REUSEPORT?
* How can I write a multi-homed server?
* How can I read only one character at a time?
* I'm trying to exec() a program from my server, and attach my socket's IO to it, but I'm not getting all the data across. Why?
