The Cloud Controller's eucalyptus user needs to have SSH access to the Walrus Controller, Cluster Controller, and Storage Controller as the eucalyptus user.

Install the Cloud Controller's eucalyptus user's public ssh key by:

• On the target controller, temporarily set a password for the eucalyptus user:

  sudo passwd eucalyptus

• Then, on the Cloud Controller:

  sudo -u eucalyptus ssh-copy-id -i /var/lib/eucalyptus/.ssh/id_rsa.pub eucalyptus@<IP_OF_NODE>

• You can now remove the password of the eucalyptus account on the target controller, if you wish:

• sudo passwd -d eucalyptus
