nfsportmon(8)
NAME
  nfsportmon - Turns the port monitor on or off

SYNOPSIS
  /usr/sbin/nfsportmon option

FLAGS
  on  Turns on the port monitor.

  off Turns off the port monitor.

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.

  Only the superuser or root can run nfsportmon.

FILES
  /etc/rc.local
      Contains the command script for automatic reboot and daemons.
