This issue occurs due to SSH server being disabled by default on the VMware vSphere Replication 6.0 appliance.
Resolution
To resolve this issue, enable SSH for the VMware vSphere Repication appliance.
To enable SSH for the VMware vSphere Replication 6.0 appliance:
Open the virtual machine console and log in as root with the password supplied during installation.
Run this script as root to enable SSH connections on the VMware vSphere Replication appliance:
/usr/bin/enable-sshd.sh
Open the /etc/hosts.allow file using a text editor.
Add the entry:
sshd : ALL : ALLOW
Note: This allows all servers to connect to the vSphere Replication appliance through SSH. If your organization has specific security requirements, you can restrict SSH access and also limit SSH access to specified users on specified hosts.
Note: The preceding links were correct as of December 30, 2015. If you find a link is broken, provide a feedback and a VMware employee will update the link.
In the /etc/ssh/sshd_config file modify the these lines to allow the root user to log in through SSH:
PermitRootLogin yes AllowGroups root
Run this command to start the SSH service:
service sshd start
Note: If the sshd service is already running, you must stop the service using service sshd stop first and then start the service usingservice sshd start otherwise the login fails.
If required, configure SSH to start on reboot:
chkconfig sshd on
