Can you clarify your answer please. I have one master node and other slave nodes. I created rsa key on my master node and copied it to all slaves. /home/mpiuser directory of all nodes are shared through NFS.The strange thing is why it requires password after I mount a slave and do ssh to the slave. When I dismount I can ssh without password.

But when I mount my slaves and run a program, it asks again passwords. $ eval `ssh-agent` $ ssh-add ~/.ssh/id_dsa The above is not working. Terminal gives the reply "Could not open a connection to your authentication agent." Help is needed urgently.
