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

NAME
     mountd -- service remote NFS mount requests

SYNOPSIS
     /sbin/mountd [-nrDd] [exportsfile]

DESCRIPTION
     Mountd is the server for NFS mount requests from NFS clients.  Mountd
     listens for service requests at a port registered with portmap(8).

     For a definition of the MOUNT protocol see Network File System Protocol
     Specification, RFC1094, Appendix A and NFS: Network File System Version 3
     Protocol Specification, Appendix I.

     Options and operands available for mountd:

     -n      The -n option allows non-root mount requests to be served.  This
             should only be specified if there are clients such as PC's, that
             require it.

     -r      The -r option allows mount RPCs requests for regular files to be
             served.  Although this seems to violate the mount protocol speci-
             fication, some diskless workstations do mount requests for their
             swapfiles and expect them to be regular files.  Since a regular
             file cannot be specified in /etc/exports, the entire file system
             in which the swapfiles resides will have to be exported with the
             -alldirs flag.

     -D      The -D option will cause mountd to log lots of information about
             its inner-workings via syslog(3) using the LOGDAEMON facility
             and the LOGDEBUG priority.

     -d      The -d option will cause mountd to not daemonize itself and it
             will log lots of information about its inner-workings to stderr
             instead of syslog(3).

     exportsfile
             The exportsfile argument specifies an alternate location for the
             exports file.

     When mountd is started, it loads the export host addresses and options
     into the kernel using the nfssvc(2) system call.  After changing the list
     of exports (either directly or indirectly via a change in netgroup mem-
     bership), a hangup signal should be sent to the mountd daemon to get it
     to reload the export information:

           kill -s HUP `cat /var/run/mountd.pid`

     Any errors encountered while processing the export entries will be logged
     via syslog(3).

FILES
     /etc/exports         the list of exported filesystems
     /var/run/mountd.pid  the pid of the currently running mountd
     /var/run/mountdtab   the current list of outstanding mounts served
     /var/run/mountdexptab
                          information about exported file systems and directo-
                          ries (UIDs, handles, ...)
