Connecting via SSH
Any user with a Palmetto Cluster account can log-in using SSH (Secure Shell) to access the terminal interface. Mac OS X and Linux systems come with an SSH client installed, while Windows users will need to download one.
SSH on Mac and Linux
Mac OS X or Linux users may open a Terminal, and type in the following command:
$ ssh email@example.com
username is your Clemson user ID. You will be prompted for both your
password and DUO authentication.

SSH on Windows
Windows has no built-in SSH client, so you will need to install some software before connecting.
MobaXterm is the recommended SSH client for Windows and can be downloaded from MobaXterm's download page. This software is recommended because it is free and comes with:
- A built-in file transfer client, which allows you to exchange files and folders between your own computer and Palmetto in a convenient manner.
- An X11 server which allows you to run graphical programs on Palmetto cluster
- A graphical port-forwarding interface to support easy access to web-based programs launched inside Palmetto
If you select the installation version of MobaXterm, you will need to unzip the downloaded file before running the installation program. Windows sometimes allow users to run the installation from inside the zipped file, resulting in missing an additional utility file (still inside the zipped file).
Connecting via MobaXterm
After downloading and installing MobaXterm, users can log-in by following these steps:
Launch the MobaXterm program
On the top-left corner of MobaXterm, click the Session button. Confirm that the following settings are set for Basic SSH settings and Advanced SSH settings:
Parameter Value Remote host
Port 22 X11-Forwarding enabled Compression enabled Remote environment Interactive shell SSH-browser type SCP (enhanced speed)
Click OK and a new session window will be opened, where you will be prompted for your Palmetto password and the DUO authentication.
After being authenticated, you will login to the login001 node.
All settings for this session are saved, and for future logins, you can select this session from the Recent sessions form of the main MobaXterm window as well as the Saved sessions tab of the side window. The side window can be displayed or hidden by clicking on the blue double-arrow sign on the top left of MobaXterm.
MobaXterm also comes with a built-in file browser and transfer GUI (SSH-browser). This GUI is accessible via the SCP tab of the side window. Using the Upload (green arrow pointing up) and and Download (blue arrow pointing down) buttons at the top of the SCP tab, you can easily transfer files between Palmetto and your local computer.
