executing the following command (as one line):

ssh root@<othernode> ‘cat /root/.ssh/authorized_keys2

>> /root/.ssh/authorized_keys’

4. Set the shell for the ssh authentication agent using the following command:

ssh-agent $BASH

5. Add the rsa identity to the ssh authentication agent

ssh-add

NOTE: To verify that the ssh keys have been set up properly, try to ssh to the other node. If not

prompted for a password, the ssh keys have been set up properly.

To run the script, follow these steps:

1. Change to the directory containing the configuration script, for example:

cd /tmp/sglx_install

2. Make sure the configuration script is executable:

When done, save and quit (“[Esc]:wq!”). You will be returned to the script for further

processing.
