are two ways to set up these permission.

1. The system administrator can setup up these permission for all users:

a) Open a shell

b) Type su to become superuser

c) cd /etc

d) Edit the file hosts.allow

Make two entries for every remote host from which access is allowed, e.g.:

sunflower

sunflower.netx.lab.com

b) Go to your home directory; type cd

c) Edit the file .rhosts

sunflower

sunflower.netx.lab.com

d) chmod 644 .rhosts
