Search the site for the keyword "SSH public key authentication". There is (thankfully) no 1:1 equivalent to .rhosts

Follow the below procedure to setup passwordless login.

Consider host1 is the server from where you are trying to do passwordless ssh to host2.

- In host1, generate a public and private key pair for root

ssh-keygen -t dsa

- In host2, go to .ssh under / and put the public key from above in authorized_keys [create it if not there and give it 644 permission]

- From host1, try ssh to host2 and say yes to add the host entry in known_hosts for future

Next time when you will do ssh host2 from host1 it will be passwordless.
