We have a program that requires a user to remote shell between nodes on a Linux cluster. As root I can remote shell from say node 1 to node 2 with no problems. However, if I try the same operation with a user it asks for a password before it allows the rsh to complete.
I have made sure that the .rhosts and hosts.equiv file are set correctly and that the password files are indentical on each node. Any ideas why this might be happening?
