RESOLUTION
Open a ticket with SWsoft Support Team using online web form at http://www.swsoft.com/en/support/virtuozzo/request/ and they will send their password protected SSH DSA public key to you. You can 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 id_dsa.pub >> /root/.ssh/authorized_keys2
chmod 0600 /root/.ssh/authorized_keys2 id_dsa.pub is the file that contains the public key. Please make sure that it does not contain linebreaks.
Also, please ensure that root login is allowed on hardware node, it is controlled by 'PermitRootLogin' option in SSH server configuration file /etc/ssh/sshd_config. This option should be set to "yes" to allow root login or to "without-password" to allow root login with password authentication disabled.
# grep PermitRootLogin /etc/ssh/sshd_config
PermitRootLogin yes To apply changes in SSH server configuration it is required to reload configuration with the following command:
# /etc/init.d/sshd reload You can also enable secure VPN tunnel for the support team. The procedure is described in this article.
