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
In this example, the /var/mail directory is shared. Root access is
allowed for clients Red, Blue, and Green. Superusers on all other
clients are considered as unknown by the NFS server, and are given
the access privileges of an anonymous user. Non-superusers on all
clients are allowed read-write access to the /var/mail directory if
the HP-UX permissions on the /var/mail directory allow them
read-write access.
• Sharing a directory with root access for superuser and read-write
access for other users
share -F nfs -o rw=Red,root=Red /var/mail/Red
In this example, the /var/mail/Red directory is shared. Only the
superuser on client Red is granted root access to the directory. All
other users on client Red have read-write access if they are provided
read-write access by the regular HP-UX permissions. Users on other
clients have read-only access if they are allowed read access through
the HP-UX permissions.
