NAME

share - make local NFS resource available for mounting by remote systems

SYNOPSIS

share [ -F nfs ] [ -o specific_options ] [ -d description  ]
pathname

DESCRIPTION

The share command makes local resources available for mounting by remote systems.

If no argument is specified, then share displays all resources currently shared, including NFS resources and resources shared through other distributed file system packages.

The following options are recognized:

-o specific_options

Specify options in a comma-separated list of keywords and attribute-value-assertions for interpretation by the file-system-type-specific command.

specific_options can be any combination of the following:

rw   Sharing will be read-write to all clients.

rw=client[:client]...

Sharing will be read-write to the listed clients; overrides the ro suboption for the clients specified.

ro   Sharing will be read-only to all clients.

ro=client[:client]...

Sharing will be read-only to the listed clients; overrides the rw suboption for the clients specified.

anon=uid

Set uid to be the effective user ID of unathenticated users if AUTH_DES authentication is used, or to be root if AUTH_UNIX authentication is used. By default, unknown users are given the effective user ID UID_NOBODY. If uid is set to -1, access is denied.

root=host[:host]...

Only root users from the specified hosts will have root access. By default, no host has root access.

secure

Clients must use the AUTH_DES authentication of RPC. AUTH_UNIX authentication is the default.

If specific_options is not specified, then by default sharing will be read-write to all clients.

-d description

Provide a comment that describes the resource to be shared.

pathname Specify the pathname of the resource to be shared.

NOTES

The command will fail if both ro and rw are  specified.   If
the  same  client name exists in both the ro= and rw= lists,
the rw will override the ro, giving read/write access to the
client specified.
ro=, rw=, and root= are guaranteed to work over UDP but  may
not work over other transport providers.
If a resource is shared with a ro= list and  a  root=  list,
any  host that is on the root= list will be given only read-
only access, regardless of whether that host is specified in
the  ro=  list, unless rw is declared as the default, or the
host is mentioned in a rw= list. The same  is  true  if  the
resource  is shared with ro as the default. For example, the
following share commands will give read-only permissions  to
hostb:
     share -F nfs -oro=hosta,root=hostb /var
     share -F nfs -oro,root=hostb /var While  the  following
     will give read/write permissions to hostb:
     share -F nfs -oro=hosta,rw=hostb,root=hostb /var
     share -F nfs -oroot=hostb /var
