NAME
       nfsportmon - Turns the port monitor on or off

SYNOPSIS
       /usr/sbin/nfsportmon option

OPTIONS
       Turns the port monitor on.  Turns the port monitor off.

DESCRIPTION
       The  nfsportmon	command turns the port monitor on or off at the kernel
       level. By default, the port monitor is turned off.

       When the port monitor is on, NFS server	port  checking	is  activated.
       This  checking  increases  system security by ensuring that file access
       requests were generated by the client kernel rather than	 by  a	forged
       application program, for example.

       Turning	the  port  monitor  on	is  only in effect until the system is
       rebooted.  To turn  the	port  monitor  on  each	 time  the  system  is
       rebooted,  edit the /etc/inet.local file and add an nfsportmon entry to
       it.

       Only the superuser or root can run nfsportmon.
