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


NAME

     mountd -- service remote NFS mount requests


SYNOPSIS

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


DESCRIPTION

     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 control-
             ling 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 operat-
             ing systems (notably Mac OS X) require this option.

     -P policy
             IPsec policy string, as described in ipsec_set_policy(3).  Multi-
             ple 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 pol-
             icy 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
             firewall.

     exportsfile
             The exportsfile argument specifies an alternative 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
     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.


FILES

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