What are TCP wrappers?

Daemons that are called from inetd that use tcp connections generally provide very little connection logging and tend to run promiscuously. Because we don't want our machine to be accessible to anyone with a computer and a network connection, we need a way to restrict access to services.

TCP wrappers allow you to define access privileges as broadly or as narrowly as you like while logging all connections.
