4 - Writing Server Applications (TCP/SOCK_STREAM)

1. How come I get "address already in use" from bind()?
2. Why don't my sockets close?
3. How can I make my server a daemon?
4. How can I listen on more than one port at a time?
5. What exactly does SO_REUSEADDR do?
6. What exactly does SO_LINGER do?
7. What exactly does SO_KEEPALIVE do?
8. How can I bind() to a port number < 1024?
9. How do I get my server to find out the client's address / hostname?
10. How should I choose a port number for my server?
11. What is the difference between SO_REUSEADDR and SO_REUSEPORT?
12. How can I write a multi-homed server?
13. How can I read only one character at a time?
14. 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?
