exportfs(1M) (NFS) exportfs(1M)
NAME
exportfs - export and unexport directories to NFS clients
SYNOPSIS
/usr/sbin/exportfs [-aiuv] [-o options] [pathname]
DESCRIPTION
The exportfs command makes a local directory or filename
available for mounting over the network by NFS clients.
Files
/etc/dfs/dfstab static export information
/etc/dfs/sharetab current state of exported pathnames
USAGE
exportfs uses information contained in the /etc/dfs/dfstab
file to export pathname (which must be specified as a full
pathname). The user with appropriate administrative
privileges can run exportfs at any time to alter the list or
characteristics of exported directories and filenames.
Directories and files that are currently exported are listed
in the file /etc/dfs/sharetab.
With no options or arguments, exportfs prints out the list of
directories and filenames currently exported.
Options
-a All. Export all pathnames listed in /etc/dfs/dfstab, or
if -u is also specified, unexport all of the currently
exported pathnames.
-i Ignore the options in /etc/dfs/dfstab. Normally,
exportfs will consult /etc/dfs/dfstab for the options
associated with the exported pathname.
-u Unexport the indicated pathname. A pathname is required
if -u is not used in conjunction with -a.
-v Verbose. Print each directory or filename as it is
exported or unexported.
-o options
Specify a comma-separated list of optional
characteristics for the pathname being exported.
options can be selected from among:

ro Export the pathname read-only. If not specified,
the pathname is exported read-write.
rw= hostname[: hostname]...
Export the pathname read-mostly. Read-mostly
means exported read-only to most machines, but
read-write to those specified. If not specified,
the pathname 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. Note that, by default, secure
NFS accepts insecure requests as anonymous, and
those wishing for extra security can disable this
feature by setting anon to -1.
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.
secure
Require clients to use a more secure protocol when
accessing the directory.
Note that you cannot export a directory that is either a
parent- or a sub-directory of one that is currently exported
and within the same file system. It would be invalid, for
example, to export both /usr and /usr/local if both
directories resided in the same disk partition.
