Sharing Tape Drive from other machine

Pls. correct me for the required steps which we need to do to share the Tape drive or whatever drive from other machine in network .

1.related files : /etc/hosts ,/etc/hosts.equiv , ....?
2. we need to insert the user & machine name inside hosts.equiv . (machinname1 username1
machinename2 username2
.........

I've done these things but when i typpe the following command from my local machine it doesn't detect that.

#mt -f "machine name":/dev/rmt/0mbn st

any other thing should be done?
thanks,

Try adding a /.rhosts file on the server with the tape drive with the servers you are backing up. Note that .rhosts files are considered insecure. And you can probably remove those hosts from the /etc/hosts.equiv file.
