NAMErpc.mountd - NFS mount daemon
DESCRIPTIONThe 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 SystemsMaking 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 FileFor every mount request received from an NFS client, rpc.mountd adds an entry to the /var/lib/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.
TCP_WRAPPERS SUPPORTThis rpc.mountd version is protected by the tcp_wrapper library. You have to give the clients access to rpc.mountd if they should be allowed to use it. To allow connects from clients of the .bar.com domain you could use the following line in /etc/hosts.allow:
You have to use the daemon name mountd for the daemon name (even if the binary has a different name).
