nfsportmon(8nfs)nfsportmon(8nfs)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.
