Symptoms
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
node#ls
If the id_rsa.pub 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
/root/.ssh
node# ssh-keygen -t rsa
2. Copy the Public Keys to the switch
Node# cat /root/.ssh/id_rsa.pub | ssh root@{IP_ADDR_switch} 'cat >> .ssh/authorized_keys'
Changes
The following link on the switch was broken:
# pwd
/root/.ssh
authorized_keys -> /config/conf/ssh/authorized_keys/root
