NAME
       exportfs - export and unexport directories to NFS clients

SYNOPSIS
       exportfs [ -avui ] [ -s server-address ] [ -o options ] [ directory ]

DESCRIPTION
       exportfs makes a local directory (or file) available for mounting
       over the network by NFS clients.  It is normally invoked at boot time
       by the rc scripts, and uses information contained in the /etc/exports
       file to export a directory (which must be specified as a full
       pathname).  A user with appropriate privilege can run exportfs at any
       time to alter the list or characteristics of exported directories.
       Directories that are currently exported  are listed in the file
       /etc/xtab.  See NOTES section for information on appropriate
       privilege.

       With no options or arguments, exportfs prints out the list of
       directories currently exported.

OPTIONS
       -a     All.  Export all directories listed in /etc/exports, or if -u
              is specified, unexport all of the currently exported
              directories.

       -v     Verbose.  Print each directory as it is exported or
              unexported.

       -u     Unexport the indicated directories.

       -i     Ignore the options in /etc/exports.  Normally, exportfs will
              consult /etc/exports for the options associated with the
              exported directory.

       -s server-address
              Export or unexport only directories which have a
              server=server-address option associated with them.

       -o options
              Specify a comma-separated list of optional characteristics for
              the directory being exported.  options can be selected from
              among:

              ro     Export the directory read-only. If not specified, the
                     directory is exported read-write.

              rw=hostname[:hostname]...
                     Export the directory read-mostly. Read-mostly means
                     exported read-only to most machines, but read-write to
                     those specified. If not specified, the directory is
                     exported read-write to all.

              anon=uid
                     If a request comes from an unknown user, use uid as the
                     effective user ID.  Note: root users (uid 0) are always
                     considered "unknown" by the NFS server, unless they are
                     included in the "root" option below. The default value
                     for this option is -2.  Setting the value of ``anon''
                     to -1 disables anonymous access.

              root=hostname[:hostname]...
                     Give root access only to the root users from a
                     specified hostname.  The default is for no hosts to be
                     granted root access.

              access=client[:client]...
                     Give mount access to each client listed.  A client can
                     either be a hostname, or a netgroup (see netgroup(4)).
                     Each client in the list is first checked for in the
                     /etc/netgroup database, and then the /etc/hosts
                     database.  The default value allows any machine to
                     mount the given directory.

FILES
       /etc/exports        static export information
       /etc/xtab           current state of exported directories
       /etc/netgroup

SEE ALSO
       exports(4), netgroup(4)

NOTES
       On a generic DG/UX system, appropriate privilege is granted by having
       an effective UID of 0 (root).  See the appropriate_privilege(5) man
       page for more information.

       On a system with DG/UX information security, appropriate privilege is
       granted by having one or more specific capabilities enabled in the
       effective capability set of the user. See the cap_defaults(5) man
       page for more information.

CAUTIONS
       You cannot export a directory that is either a parent- or a sub-
       directory of one that is currently exported and within the same
       filesystem.  It would be illegal, for example, to export both /usr
       and /usr/local if both directories resided in the same virtual disk.
