1. Using the vSphere Web Client, open a console connection to the VDP appliance and log in using root and the password configured when the appliance was deployed. You can also use the latest version of VMware Fusion to connect to vSphere hosts and open console connections to VMs (screen shot below) - sweet!
2. Change the working directory to /etc/ssh by typing cd /etc/ssh
3. Use the vi editor to edit the sshd_config file in this directory. If you are not familiar with the vi editor, it is best to learn a bit about it before editing files – especially configuration files. A good vi reference page can be found here. Type vi sshd_config to open the file for editing.
4. Using the down arrow key, locate this line in the file: #PermitRootLogin yes
5. Place the cursor at the beginning of the line using the arrow keys.
6. Delete the # at the beginning of the line by pressing x. The word “yes” will likely change to a different color.
7. Save the file by entering :wq!
8. For the change to take effect, you must restart sshd with this command: /etc/init.d/sshd restart
You should now be able to log in from an ssh client.
To disable this access, simply edit the sshd_config file and reinsert the # in front of PermitRootLogin yes. Be sure to restart sshd for the change to take effect.
