description="
Monitor of incoming TCP connections.

TCP Wrapper is a host-based Networking ACL system, used to
filter network access to Internet Protocol servers on
(Unix-like) operating systems such as Linux or BSD.

It allows host or subnetwork IP addresses, names and/or
ident query replies, to be used as tokens on which to
filter for access control purposes.
