rpc.mountd − NFS mount daemon
/usr/sbin/rpc.mountd [options]
The rpc.mountd program implements the NFS mount protocol. When receiving a MOUNT request from an NFS client, it checks the request against the list of currently exported file systems. If the client is permitted to mount the file system, rpc.mountd obtains a file handle for requested directory and returns it to the client.
Exporting
NFS File Systems
Making file systems available to NFS clients is called
exporting.
Usually, a file system and the hosts it should be made available to are listed in the /etc/exports file, and invoking exportfs -a whenever the system is booted. The exportfs(8) command makes export information available to both the kernel NFS server module and the rpc.mountd daemon.
Alternatively, you can export individual directories temporarily using exportfs’s host:/directory syntax.
The rmtab
File
For every mount request received from an NFS client,
rpc.mountd adds an entry to the
/var/state/nfs/rmtab file. When receiving an unmount
request, that entry is removed. user level part of the NFS
service.
However, this file is mostly ornamental. One, the client can continue to use the file handle even after calling rpc.mountd’s UMOUNT procedure. And two, if a client reboots without notifying rpc.mountd, a stale entry will remain in rmtab.
−N or −−no-nfs-version
This option can be used to request that rpc.mountd does not offer certain versions of NFS. The current version of rpc.mountd can support both NFS version 2 and the newer version 3. If the NFS kernel module was compiled without support for NFSv3, rpc.mountd must be invoked with the option −−no-nfs-version 3.
−v or −−version
Print the version of rpc.mountd and exit.
