Secure Shell (SSH) is a cryptographic network protocol for operating network services securely over an unsecured network. At the School of Computer Science, we use ssh for remote connection logins to our computers.

Logging in to Linux using SSH

There are two ways to login to a remote Linux server using SSH:

  1. terminal server (text only)
  2. remote desktop (graphical/X11)
    Not all servers support X11-sessions. Check the servers’ capabilities for remote desktop connections.

IMPORTANT: Carleton is behind a firewall. If you are outside of Carleton, you will need to VPN to Carleton first before you can access the SCS server resources. Refer to the Remote Access (VPN) information.

Login using ssh to Linux using the terminal

If your computer is running Windows, you can use the free putty utility as your ssh client.

Login using ssh to Linux using the graphical method

At SCS, we use the x2go client to connect to a Linux host graphically (using X11).

ssh-key logins

We encourage the use of ssh-key logins as it is both a convenient and safe way to ssh to your destination host without needing a password.
See the Passwordless SSH With Key Pairs article for detailed instructions.
