This daemon handles file-system mount requests from remote systems and provides access control. The mountd daemon checks /etc/dfs/sharetab to determine which file systems are available for remote mounting and which systems are allowed to do the remote mounting. You can use the -v option and the -r option with this command. See the mountd(1M) man page.
The -v option runs the command in verbose mode. Every time an NFS server determines the access that a client should be granted, a message is printed on the console. The information that is generated can be useful when trying to determine why a client cannot access a file system.
The -r option rejects all future mount requests from clients. This option does not affect clients that already have a file system mounted.
NFS version 4 does not use this daemon.
