I do not have Telnet loaded on any of my systems, and I use tcp_wrappers
to tightly control which remote sites can access any sites via ftp or
secure_shell.

Every day the logwatch report show many, many sites that attempted to
access the various systems, but were rejected by tcp_wrapper.  I don't
leave any system open with the default configuration and module loads.
