The /etc/exports file controls what filesystems you
wish to export. Its format is as follows:
directory hostname(options) |
The (options) are
not required. For example:
/mnt/export speedy.redhat.com |
would allow users from speedy.redhat.com to mount
/mnt/export with the default read-only permissions, but:
/mnt/export speedy.redhat.com(rw) |
would allow users from speedy.redhat.com to mount
/mnt/export with read-write priviledges.
 | 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:
/mnt/export speedy.redhat.com(rw)
/mnt/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:
On the server that is exporting NFS filesystems, the
nfs service must be running.
View the status of the NFS daemon with the command
Start the NFS daemon with the command
Stop the NFS daemon with the command
To start the nfs service at boot time, use the command:
/sbin/chkconfig --level 345 nfs on |
You can also use ntsysv or
serviceconf to configure which services start
at boot time. Refer to Chapter 8 for details.
