exportfs(1M)                      NFS R4.11                     exportfs(1M)


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 appropriateprivilege(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 capdefaults(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.
