EXPORTFS(8)EXPORTFS(8)NAMEexportfs - export and unexport directories to NFS clients
SYNOPSIS
/usr/etc/exportfs [ -avui ] [ -o options ] [ directory ]
DESCRIPTIONexportfs makes a local directory (or file) available for mounting over
the network by NFS clients. It is normally invoked at boot time by the
/etc/rc.local script, and uses information contained in the exports
list (either the /etc/exports file or the NetInfo /exports directory)
to export a directory (which must be specified as a full pathname).
The super-user 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.
With no options or arguments, exportfs prints out the list of
directories currently exported.
OPTIONS-a All. Export all directories listed in the exports list 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 the exports list. Normally, exportfs will
consult the exports list for the options associated with the
exported directory.
-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(5)).
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 ALSOexports(5), netgroup(5)WARNINGS
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 disk partition.
