restricting nfs to specific server

[EU-Admins-UNIX]

Hi

in my /etc/dfs/dfstab, I have managed to restirct the rw access to a specific server, but is there anyway of restricting the number of servers that can actually mount the file system?  i.e. as it stands, other systems can mount the FS but not write to it.

share -F nfs -o rw=server /opt/coins9/live
share -F nfs -o rw=server /opt/coins9/training
share -F nfs -o rw=server /opt/coins9/test1
share -F nfs -o rw=server /opt/coins9/copy1

I want to restrict the mounting of the FS to 'server'.

Regards

From "man share":

rw=client[:client] ...

    Share the pathname read-mostly if sec= option is not provided. Read-mostly means read-write to those clients specified and read-only for all other systems. If a sec= option is provided, pathname is shared read/write only to the listed clients. No other systems can access pathname.

In other words, you'll need to share your filesystems like this:

share -F nfs -o sec=sys,rw=server /opt/coins9/live
