Beside accessing the console from vSphere Client, we can use SSH to remote access a Stratusphere appliance's console. You need a SSH client first. On Windows, the most popular (and free) SSH client is PuTTY (http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html). If you are using a Mac or a Linux machine, it already has SSH client built-in, which you can run from Terminal/Console.
To start, run the SSH client and it will ask you to put in the machine name or IPl.

Once you connect, it may prompt you for a security alert asking you about the host key:

Click "Yes" and continue. The login credential you need to use here is 'friend/sspassword' for on-premises appliances. We disable privileged account (i.e. root) to have direct SSH access for security reasons, so you will need to login as 'friend' then run 'sudo bash' to switch to root. After putting the password, it will return you with the command prompt with root access.
If you run from a Mac or a Linux machine, you can bring up Terminal or Console, and run the command 'ssh friend@<host-fqdn-or-ip>'. Follow the same instruction above to switch to root. This should work in WIndows CMD as long as SSH is enabled on the desktop.
For cloud appliances, the default user is ec2-user for AWS. Azure allows you choose any username. You can run a command in the following format to SSH with private key authenication:
ssh -i <path-to-key-pair-file.pem> azureuser@<azure-ip.or.dns>
ssh -i <path-to-key-pair-file.pem> ec2-user@<aws-ip.or.dns>
