how can i use a rlogin with out entered a password,

someone tell me about configure the next files

/.rhosts

/etc/hosts.equiv and /etc/hosts

but i not sure about that, or there are not enough


could you tell me how to do that?

You could search this site and find many post on the subject.

A good one is this post that mentions why you might want to reconsider doing it at all.

The only thing you need to do is this. Add your user ID and the hostname for each box on the other box.

On host1:
#vi /.rhosts
host2 user1


On host2:
#vi /.rhosts
host1 user1


I would not recommend using hosts.equiv as it gives equivalent user privledges for root. Any other user might be okay, but I don't use it on my boxes.

My recommendation is to use SSH with a client side digital certificate with no PIN or password, if security is a concern and you control the client.

When you connect with SSH you can authenticate based on your client-side certificate that only works with your client-server digital key(s) combination. That way, you can connect without a password via a secure cryptographic tunnel (using digital certificates).

We never use any "R" commands... there are too many good and secure alternatives these days. (unless you have a very good, compelling reason, you should consider alternatives, IMHO).
