# hosts.deny  This file contains access rules which are used to

#      deny connections to network services that either use

#      the tcp_wrappers library or that have been

#      started through a tcp_wrappers-enabled xinetd.

#

#      The rules in this file can also be set up in

#      /etc/hosts.allow with a 'deny' option instead.

#

#      See 'man 5 hosts_options' and 'man 5 hosts_access'

#      for information on rule syntax.

#      See 'man tcpd' for information on tcp_wrappers
