Logging into CCAST using SSH

Notice: If you are looking for resources on HyFlex teaching, please visit our Teach HyFlex Page

This document describes how to login to CCAST using the SSH protocol.

Overview

The primary method of accessing CCAST resources is using a Secure Shell (SSH). SSH is a terminal-based (i.e. command line) protocol that facilitates connection to and interaction with remote servers via text-based commands. Instructions for using SSH differ depending on what kind of computer you have.

Connecting to CCAST from a Windows PC using PuTTY

PuTTY is a third-party application that implements the SSH protocol on Windows computers, and can be downloaded here. Follow the on-screen instructions for the Windows installer (.msi) file to install PuTTY on your computer.

Once installed, open PuTTY and enter the hostname for the machine you want to login to. For the Thunder cluster, this will be thunder.ccast.ndsu.edu (see screenshot below).

Then click "Open" to initiate the connection. A terminal window will open and you will be prompted for a username. Enter your NDSU first.last ID and hit enter, then enter the password associated with your NDSU account. Note: When you type your password, you will not see anything display at the prompt. This is normal.

If the username and password are accepted, you will be greeted with several login messages. Please do not ignore these, as they contain important information about your CCAST account.

Connecting to CCAST from a Mac or Linux Computer

MacOS and Linux both have an integrated terminal and a native SSH client, so no third-party software is required to connect to CCAST using these operating systems. Instructions for both types of systems are the same.

First, locate and launch the terminal app by search for "terminal" in your applications. Depending on your environment, you should see a window resembling the one below (example taken from a Mac).

To connect to CCAST (for example, the Thunder cluster), run the following command:

ssh username@thunder.ccast.ndsu.edu

Where your username is your NDSU first.last ID. When prompted for a password, enter the password associated with your NDSU account. Note: When you type your password, you will not see anything display at the prompt. This is normal.

If the username and password are accepted, you will be greeted with several login messages. Please do not ignore these, as they contain important information about your CCAST account.
