EXPORTFS(8) COMMAND REFERENCE EXPORTFS(8)
NAME
exportfs - export and unexport directories to NFS clients
SYNOPSIS
/usr/etc/exportfs [ -avui ] [ -o options ] [ directory ]
DESCRIPTION
exportfs makes a local directory (or file) available for
mounting over the network by NFS clients. It uses
information contained in the /etc/exports file 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 /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.
-l Default options are listed below.
-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
CAVEATS
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.
