  1. Open a ticket with Odin Support Team using online web form:

  2. Download SSH DSA public key here.

  3. Add that key to the authorized keys list on the hardware node using the following commands:

    mkdir -p /root/.ssh
    chmod 0700 /root/.ssh
    cat >> /root/.ssh/authorized_keys2
    chmod 0600 /root/.ssh/authorized_keys2
 is the file that contains the public key. Please make sure that it does not contain linebreaks.

  4. Ensure that root login is allowed on the hardware node. It is controlled by PermitRootLogin option in SSH server configuration file /etc/ssh/sshd_config:

    # grep PermitRootLogin /etc/ssh/sshd_config
    PermitRootLogin yes
    #yes - allow root login. 
    #without-password - allow root login with password authentication disabled.

    Note: To apply changes in SSH server configuration it is required to reload configuration with the following command:

    # /etc/init.d/sshd reload
  5. Additionally you can also enable secure VPN tunnel for the support team. The procedure is described in the following articles:
