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.
