You might want to try ssh with the verbose option on so that you can tell exactly what is wrong (though we can probably guess what what you mentioned).
The key here is to maintain the following files/directories to be the same across the cluster/headnode/non-node:
1) /etc/passwd 2) /etc/shadow 3) /home/<username>/.ssh
If those three items are the same across the computers, you should really be able to traverse between them without having to type the password. Maybe you can post the output of 'ssh -v <nodename>' if you think it will provide us with some hints.
Cheers,
Bernard
P.S. I assume you are using OSCAR v2.3.1 or later?

Ok, I made the changes shown below and also the RhostsAuthentication is currently set to yes. After making these changes and restarting the ssh service, I still am prompted for a password for the users.
More information that may be helpful is that the OSCAR Server is RH 7.3 and the non-node machine is a RH9 box. Any other thoughts would be appreciated.
Thanks for the help, Ben Simmons

Make sure you have the following in /etc/ssh/sshd_config on your target machines:
RhostsRSAAuthentication yes RSAAuthentication yes
(then restart or sighup the sshd process for changes to take effect, of course)

Hi all,
I followed the instructions on the list posted earlier about just copying the .ssh folder for root from the server to the non-node in question. This works fine for my root user between the two machines, but I also need to have the users be able to transaprently login to this non-node as well. I have the home directories mounted in /home over an nfs mount and the passwd and group files synced, but I am not clear how to make the password prompt go away for a user too. When I read through the OSCAR install scripts, everywhere I see a discussion on this matter, it says that it is automatically handled by the cross mount of home directories.
Am i overlooking something simple, or can someone show me how to correct this process.
Thanks in advance,
