W.R. Stevens "Unix Network Programming" (pp.303-304) suggests using
port number above 5000. Reason being that some of the ports between
1024 and 5000 may have been already assigned automatically to other
processes. System doesn't automatically assign port numbers higher
than 5000. If you use the number between 1024-5000, you, therefore
in rare occasions, may get bind() error if port # you want to use
happen to be already in use.
The book is great!
