NFS Services Administrator's Guide (5900-1632, August 2011)

-o Enables you to use some of the specific options of the share command, such as sec,
async, public, and others.
-d Enables you to describe the filesystem being shared
When NFS is restarted or the system is rebooted, the /etc/dfs/dfstab file is read and all
directories are shared automatically.
2. Share all the directories configured in the /etc/dfs/dfstab file without restarting the server
by using the following command:
shareall
This command reads the entries in the /etc/dfs/dfstab file and shares all the directories.
3. Verify that your filesystem is shared by entering the following command:
share
An output similar to the following output is displayed:
/home rw=Developers, ro= "home dirs"
All the directories that you have shared must be present in this list.
Manual Share
To share your directories manually, follow these steps:
1. Enter the following command to add a directory to the server’s internal list of shared directories:
share -F nfs directory_name
2. Enter the following command to verify if your filesystem is shared:
share
An output similar to the following output is displayed:
/tmp rw=hpdfs001.cup.hp.com ““
/mail rw ““
/var rw ““
The directory that you have shared must be present in this list.
For more information on the share command and a list of share options, see share_nfs(1M) and
share(1M).
Examples for Sharing directories
This section discusses different examples for sharing directories.
• Sharing a directory with read-only access
share -F nfs -o ro /tmp
In this example, all clients are allowed read-only access to the /tmp directory. The /tmp
directory needs to be configured to allow read access to users on the clients. For example,
specify -r--r--r-- permissions for the /tmp directory.
• Sharing a directory with varying access permissions
share -F nfs -o ro=Jan:Feb,rw=Mar /usr/kc
In this example, the /usr/kc directory is shared with clients Jan, Feb, and Mar. The rw
option specifies that users on client Mar have read-write access to the /usr/kc directory.
The ro option specifies that users on Jan and Feb have read-only access.
In addition to the share options, the HP-UX permissions for the /usr/kc directory must be
set to allow access to all users or group that includes the users on Jan, Feb, and Mar.
• Sharing a directory with root access for clients
share -F nfs -o root=Red:Blue:Green /var/mail
