Connecting Remotely to CAE Linux Machines from Windows (Terminal Only)

How to remotely connect to a CAE Linux lab machine to use command line (no graphical user interface)

Connecting from Windows

1. Command Line or GUI?: You can use an SSH client to remotely connect to a CAE Linux lab machine and access command line operations. If you want to remotely connect to a CAE Linux lab machine and have a graphical user interface, please see this article:

2. Choose an SSH client: There are numerous SSH clients, many of them downloadable for free. On CAE Windows lab machines, the installed SSH client is PuTTY (one of the free clients) so we'll use this program in the example below. You can launch it by searching "putty" in the Start menu and selecting it.

3. Connection Settings: Enter into the Host Name field (step 1 in the graphic below), make sure the connection type is SSH, and select Open at the bottom of the PuTTY window (step 2 in the graphic below).

4. Accept Host Key (if needed): Your SSH client may not recognize the host key for, and bring up a security warning. This can happen if it's your first time connecting, or if you've refreshed PuTTY's cache of accepted keys (which will happen on CAE machines when the machines refresh every few days). You can click Yes to accept the host key and add it to PuTTY's cache for future recognition. For a slightly more in-depth look at this, please see KB Accepting the best-tux Host Key in Windows

5. Enter Login Credentials: PuTTY will then load the command line, first asking for your CAE user name, and then your password. Very occasionally, PuTTY will error out at this stage or immediately after, in which case just go through the setup again, and it should work.

6. Perform desired command line operations: After credentials have been verified, you'll see the welcome screen, and be able to perform command line options on the CAE Linux lab machine that your connection was routed to. As the name implies, connecting to will connect you to the CAE Linux lab machine, with the least load, "best" for working on.

7. Disconnect properly: when you're ready to end your session, type and enter either logout or exit and PuTTY will disconnect your session as well as close the window. Simply closing the PuTTY window will leave your connection open; not optimal, less safe.
