Background Information

When you initiate an SSH connection to a running server, the RightScale Dashboard lets you use a Java Web Start application, a Java Applet, or ssh:// protocol links for launching your SSH session. You can specify your SSH client preference under Settings -> User Settings -> SSH.

Before you can SSH into a machine, you must first ensure that port 22 is open for the security group that the server belongs to.

Note: If you are using the Java Web Start Application or Java Applet for launching your SSH session from RightScale you will need Java installed (5.0 Update 9 or later). You can verify whether Java is enabled for your browser here, and download Java (if needed) here.


In order to start an SSH session, RightScale must determine which terminal emulator to use and which SSH client to use. This choice is influenced by which operating system you are running and by the applications you have installed.

If you are running Microsoft Windows, a terminal emulator program is not always needed; GUI SSH clients such as PuTTY provide their own terminal emulator functionality. However, Windows does not ship with an SSH client pre-installed. Therefore, you will need to install one before using SSH:

Mac OS X and Linux both ship with OpenSSH, so an SSH client is always available. However, a separate terminal program is required under both operating systems, and the choice of which terminal program to use is not always clear.

The RightScale SSH launcher currently uses a hard-coded list of terminal programs and clients for each OS. It scans through the list in order and launches the first available client. At this time, there is no way for end users to influence the order in which we select the client application to use.

SSH Client Notes
PuTTY Must be installed to C:\Program Files (x86)\PuTTY\
Windows Command Prompt + OpenSSH Should be installed to a folder named OpenSSH under Program Files.
Windows Command Prompt + Generic SSH client If a program named SSH.exe is found anywhere in your search path, the launcher prompts you to invoke it. The client's command-line interface should be OpenSSH-compatible.

If you choose to use ssh:// protocol links to ssh into your servers, you will need to make sure your private key is added to your authentication agent.  OpenSSH in particular defaults to id_rsa, which may not be the right key to use to ssh into your Servers.

To resolve this issue, download your private key from Cloud Management dashboard under Settings -> User Settings -> SSH.

Then on the command prompt, run the ssh-add command with the recently downloaded private key file name. This will add your private key identity to the authentication agent.
