UNIX for Advanced & Expert Users

Thanks for the help guys...

I got it worked, one of my friend helped me...we just need to add the
rsa - public key of the client to the authorized_keys file in the .ssh directory of the user in the server..

u can do it by the following commands

ssh-keygen -t rsa ---- this will create the rsa key in the client.


create a directory called ".ssh" in the home directory of "root" in the server, if it is not present.


cat /root/.ssh/id_rsa.pub | ssh root@<ip> 'cat >> /root/.ssh/authorized_keys'



That's it..............

By your description you didn't set up Host Based Authentication, but plain old simple Public Key Authentication. BIG difference if one know what these 2 terms really mean, and as such it's no wonder our solution was different from what you wanted.

Thanks man...
As i have posted before iam a newbie to linux...
i was trying to learn hostbasedauthentication, one of my friend offered this solution for a passwordless authentication, i assumed it was hostbased.
Thanks for your reply, so that i came to know the difference between the public key authentication and hostbasedauthentication...
Thanks a lot ....
