MOUNTD(8)                   System Manager's Manual                  MOUNTD(8)

     mountd - service remote NFS mount requests

     mountd [-dN] [-P policy] [-p port] [exportsfile ...]

     mountd is the server for NFS mount requests from other client machines.
     mountd listens for service requests at the port indicated in the NFS
     server specification; see Network File System Protocol Specification, RFC
     1094, Appendix A and NFS: Network File System Version 3 Protocol
     Specification, Appendix I.

     Options and operands available for mountd:

     -d      Enable debugging mode.  mountd will not detach from the
             controlling terminal and will print debugging messages to stderr.

     -N      Do not require privileged ports for mount or NFS RPC calls.  This
             option is equivalent to specifying "-noresvport -noresvmnt" on
             every export.  See exports(5) for more information.  Some
             operating systems (notably Mac OS X) require this option.

     -P policy
             IPsec policy string, as described in ipsec_set_policy(3).
             Multiple IPsec policy strings may be specified by using a
             semicolon as a separator.  If conflicting policy strings are
             found in a single line, the last string will take effect.  If an
             invalid IPsec policy string is used mountd logs an error message
             and terminates itself.

     -p port
             Force mountd to bind to the given port.  If this option is not
             given, mountd may bind to every anonymous port (in the range
             600-1023) which causes trouble when trying to use NFS through a

             The exportsfile argument specifies an alternative location for
             the exports file.  Multiple exports files can be defined.

     When mountd is started, it loads the export host addresses and options
     into the kernel using the nfssvc(2) system call.  After changing the
     exports file, a hangup signal should be sent to the mountd daemon to get
     it to reload the export information.  After sending the SIGHUP (kill -s
     HUP `cat /var/run/mountd.pid`), check the syslog output to see if mountd
     logged any parsing errors in the exports file.

     After receiving SIGTERM, mountd sends a broadcast request to remove the
     mount list from all the clients.  This can take a long time, since the
     broadcast request waits for each client to respond.

     /etc/exports         the list of exported filesystems
     /var/run/mountd.pid  the pid of the currently running mountd
     /var/db/mountdtab    the list of remotely mounted filesystems

     nfsstat(1), nfssvc(2), ipsec_set_policy(3), exports(5), nfsd(8),
     rpcbind(8), showmount(8)

     The mountd utility first appeared in 4.4BSD.
