nfsportmon - Turns the port monitor on or off
on Turns the port monitor on.
off Turns the port monitor off.
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.
