Chapter 10. Network File System (NFS) 105
10.3. Exporting NFS Filesystems
The /etc/exports file controls what filesystems the NFS server exports. Its format is as
follows:
directory hostname(options)
The (options) are not required. For example:
/misc/export speedy.redhat.com
would allow users from speedy.redhat.com to mount /misc/export with the default read-
only permissions, but:
/misc/export speedy.redhat.com(rw)
would allow users from speedy.redhat.com to mount /misc/export with read-write priv-
ileges.
Caution
Be careful with spaces in the /etc/exports file. If there are no spaces between the hostname and
the options in parentheses, the options apply only to the hostname. If there is a space between
the hostname and the options, the options apply to the rest of the world. For example, examine the
following lines:
/misc/export speedy.redhat.com(rw)
/misc/export speedy.redhat.com (rw)
The first line grants users from speedy.redhat.com read-write access and denies all other users.
The second line grants users from speedy.redhat.com read-only access (the default) and allows the
rest of the world read-write access.
Refer to the Official Red Hat Linux Reference Guide for a list of options that can be specified in
the /etc/exports file.
Each time you change /etc/exports, you must tell the NFS daemons to examine it for new
information, or reload the configuration file:
/sbin/service nfs reload
10.3.1. Starting and Stopping the Server
On the server that is exporting NFS filesystems, the nfs service must be running.
View the status of the NFS daemon with the command
/sbin/service nfs status
Start the NFS daemon with the command
/sbin/service nfs start
Stop the NFS daemon with the command
/sbin/service nfs stop
To start the nfs service at boot time, use the command:
