No IP Spoofing prevention #16

Closed Thireus closed 8 years ago

Thireus commented 9 years ago

man /etc/host.conf:

   nospoof
          Valid values are on and off.  If set to on, the resolv+
          library will attempt to prevent hostname spoofing to enhance
          the security of rlogin and rsh.  It works as follows: after
          performing a host address lookup, resolv+ will perform a
          hostname lookup for that address.  If the two hostnames do not
          match, the query will fail.  The default value is off.

This option is missing in host.conf.
