exportfs(1M) exportfs(1M)

NAME

exportfs - export and unexport directories to NFS clients

SYNOPSIS

/usr/sbin/exportfs [-auv]

/usr/sbin/exportfs [-uv][dir ...]

/usr/sbin/exportfs -i [-o options][-v][dir ...]

DESCRIPTION

The exportfs command makes a local directory or ﬁle available to NFS clients for mounting over the

network. Directories and ﬁles cannot be NFS-mounted unless they are ﬁrst exported by exportfs.

exportfs is normally invoked at boot time by the /sbin/init.d/nfs.server script, and uses

information contained in the /etc/exports ﬁle to export the ﬁle or ﬁle system named by each dir,

which must be speciﬁed as a full path name.

If no options or arguments are speciﬁed in the command line, exportfs displays a list of the currently

exported directories and ﬁles on standard output.

A superuser can run exportfs at any time to alter the list or characteristics of exported directories and

ﬁles.

Options

exportfs recognizes the following options:

-a Export all directories listed in /etc/exports .If-u is also speciﬁed, unexport all of the

currently exported directories.

-i Ignore the options in /etc/exports . Normally, exportfs consults /etc/exports for

the options associated with the exported directory.

-u Unexport the indicated directories.

-v Verbose. Print each directory or ﬁle name as it is exported or unexported.

-o options

Specify a comma-separated list of optional characteristics for the directory being exported. The

list of options can include any of the following:

async

All NFS Protocol Version 2 mounts will be asynchronous. This option is ignored for NFS

PV3. Refer to exports(4) for warnings when using this option.

ro Export the directory read-only. If not speciﬁed, the directory is exported read-write. The

ro and rw options cannot be used on the same exportfs command line.

rw=hostname[:hostname]...

Export the directory read-mostly. Read-mostly means read-only to most machines, but

read-write to those speciﬁed. If neither ro nor rw is speciﬁed, the directory is exported

read-write to all. The ro and rw options cannot be used on the same exportfs com-

mand line. Up to 256 hostnames can be speciﬁed. With a server conﬁgured for DNS nam-

ing in the nsswitch "hosts" entry, any hostname must be represented as a fully qualiﬁed

DNS name. Currently HP-UX will attempt to match a non-fully qualiﬁed hostname; this

HP-only feature will be obsoleted in a later release of HP-UX.

anon=uid

If a request comes from an unknown user, use uid as the effective user ID.

Root users (user ID 0) are always treated as user unknown by the NFS server unless they

are included in the root option below.

If the client is a UNIX system, only root users are considered unknown. All other users

are recognized even if they are not in /etc/passwd .

The default value for uid is the user ID of user nobody. If user nobody does not exist,

the value −2 is used. 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
