directories to export to NFS clients
directory [ -option[, option ]] ...
The /etc/exports file contains entries for
directories that can be exported to NFS clients. This
file is read automatically by the
command. If you change this file, you must run
for the changes to affect the mount daemon's operation.
Only when this file is present at boot time does the
NFS startup script execute
and start the NFS file-system daemon,
and the mount daemon,
The /etc/xtab file contains entries for
directories that are currently exported. This
file should not be modified by users. (Use the
-u option of exportfs to remove entries
from this file.)
An entry for a directory consists of a line with the form
shown in the ``Format'' section where:
is the pathname of a directory (or file)
is one of the following:
export the directory read-only.
If not specified, the directory is exported read-write.
export the directory read-mostly.
Read-mostly means read-only to most machines,
but read-write to those specified.
If not specified, the directory is exported read-write to all.
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
anon to -1 disables anonymous access.
By default NFS will accept insecure requests as
anonymous, and those wishing for extra security can disable
this feature by setting anon to -1.
give root access only to the root users from
a specified hostname. The default is for no hosts to be
granted root access.
give mount access to each client listed. A
client can either be a host name, or a net group
Each client in the list is first checked for in the
netgroup database, and then the host's database. The default
value allows any machine to mount the given directory.
A ``#'' (pound-sign) anywhere in the file
indicates a comment that extends to the end of the line.
/usr -access=clients #export to my clients
/usr/local #export to the world
/usr2 -access=hermes:zip:tutorial #export to only these machines
/usr/sun -root=hermes:zip #give root access only to these
/usr/new -anon=0 #give all machines root access
/usr/bin -ro #export read-only to everyone
/usr/stuff -access=zip,anon=-3,ro #several options on one line
You cannot export either a parent directory or a
subdirectory of an exported directory that is within the
same filesystem. It would be illegal, for instance, to
export both /usr and /usr/local if both
directories resided on the same disk partition.
