Name
       nfsportmon - turn on or off the port monitor

Syntax
       /etc/nfsportmon option

Description
       The 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.

       Only the superuser or root can run

Options
       on     Turn on the port monitor.

       off    Turn off the port monitor.
