Using the following procedure to configure passwordless ssh from a node to the Infiniband switch, ssh is still prompting for a password:

1. Ensure the node you want to ssh from has public keys in the ~root/.ssh directory.

Logged in as root:
node# cd root/.ssh
If the exists, your done with this step.

If it doesn't already exist, generate keys as follows only on the nodes you want to be able to loging from passwordless:
IMPORTANT: DON'T use a Passphrase for passwordless ssh!!!!

node# cd /root/.ssh
node# pwd
node# ssh-keygen -t rsa


2. Copy the Public Keys to the switch

Node# cat /root/.ssh/ | ssh root@{IP_ADDR_switch} 'cat >> .ssh/authorized_keys'



 The following link on the switch was broken:

# pwd

authorized_keys -> /config/conf/ssh/authorized_keys/root
