mountd, rpc.mountd - server for NFS mount requests and NFS access
is an RPC server that answers requests for NFS access information and
file system mount requests. It reads the file to determine which file
systems are available for mounting by which remote machines. See
sharetab(4). running on the local server will contact the first time
an NFS client tries to access the file system to determine whether the
client should get read-write, read-only, or no access. This access can
be dependent on the security mode used in the remote procedure call
from the client. See share_nfs(1M).
The command also provides information as to what file systems are
mounted by which clients. This information can be printed using the
The daemon is automatically invoked if and in
Only superuser can run the daemon.
The following options are supported:
This is an obsolete option. All messages and errors are logged
Reject mount requests from clients. Clients that have file sys‐
mounted will not be affected.

If is running, must also be running in order to be assured that the NFS
server can respond to requests.
Some routines that compare hostnames use case-sensitive string compar‐
isons; some do not. If an incoming request fails, verify that the case
of the hostname in the file to be parsed matches the case of the host‐
name called for, and attempt the request again.
If a client crashes, executing on the server will show that the client
still has a file system mounted. In other words, stale entries may
accumulate in for clients that crash without sending an unmount
Also, if a client mounts the same remote directory twice, only one
entry appears in Doing a of one of these directories removes the single
entry and no longer indicates that the remote directory is mounted.
