Getting Started
This document will help you get started with requesting a user account as well as accessing any of the supported RSS clusters. Please follow all of the instructions to help expedite the account request process.
Get an Account
You need to request an account for using Lewis cluster. Following are the steps to get an account:
Step 1: Open a terminal
Open your favorite terminal app. For our Windows users we recommend MobaXterm.
Step 2: Find or create your SSH Public Key
Find your existing SSH public key with the command cat ~/.ssh/id_rsa.pub
.
If you don't have a key you will need to create a new SSH Key Pair.
Step 3: Request an account
Fill out the Lewis Account Request Form.
Note: contact us if:
- You have an account and have any issue to login Lewis (do not resubmit the form)
- You do not have a University of Missouri System login
Step 4: Check your email
You will get an email from Research Computing once your account is ready.
Logging into Lewis
To log into Lewis, type the following in a local terminal:
ssh <username>@lewis.rnet.missouri.edu
The first time you log in you will see a message like this:
[<username>.<your_computer_name_here>] ➤ ssh <username>@lewis.rnet.missouri.edu
Warning: Permanently added 'lewis.rnet.missouri.edu' (ECDSA)
to the list of known hosts.

That warning is telling you that you are logging into a computer you have never seen before - it is expected on your first login. The passphrase is the one created in step 3.
Logging into Clark
To log in Clark cluster, you only need a UM username and password. Open your favorite terminal app, for our Windows users we recommend MobaXterm, and type:
ssh <username>@clark.rnet.missouri.edu
Transfer Your Data to the Cluster
There are multiple ways to transfer your data to the cluster. On Windows drag
and drop files into your MobaXterm window. For Linux and Mac OS use the
rsync
or scp
commands to copy data to the cluster.
Transfers to/from the cluster that include large files (gigabyte or larger) and/or many files (hundreds or more) will need to use one of Data Transfer Nodes (DTN). Review Data Transfer to learn more.
