Overview
The SSH (Secure SHell) protocol provides a secure communication channel over a potentially-unsecured network. This is mostly commonly used as a way to access a command-line interface on a remote computer.
To connect to IST Linux servers (such as CCL), you first will need to request "IPA (UNIX)" access in signUM.
How does it work?
Software
Open Area Computer Labs/Managed workstations
PuTTY and SSH are pre-installed on instructional computers in IST Open-Area Computer Labs, accessible from the INS Programs > Unix-Linux menu.
If you do not have administrative access to your IST-managed workstation, please create an IT Ticket.
Home computers/laptops or mobile devices
- Windows: PuTTY is the most popular client. Windows 10 now includes SSH and can be run from a Command Prompt or PowerShell window, as "ssh [email protected]" for example.
- Mac / Linux: these operating systems are pre-installed with an SSH client. Just open a Terminal window and use the "ssh [email protected]" command.
- Mobile: Several app options exist for all major OSes. Be sure to choose a trusted client.
Connecting to IST Linux
- To connect to IST Linux from home / off campus, you need to first connect to the UM VPN. When using campus Wi-Fi, ensure that you are connected to uofm-secure, as uofm-guest and other connections will also require a VPN connection.
Using an SSH client, connect to "ccl.cc.umanitoba.ca" using your UMnetID (without the "@myumanitoba.ca" or similar).
If you have access to a commandline shell, use ssh [email protected].
If asked about the server's host key fingerprint, verify that it matches one of the below:
- Ed25519: 22:0c:30:88:9b:c8:84:dd:17:a7:4b:40:76:02:9c:be
- ECDSA: 8b:a7:b7:b1:a7:cc:76:54:5d:9b:0e:4d:56:00:84:4e
- RSA: 10:09:04:ab:43:c2:0e:e2:3e:ad:36:93:42:33:cf:fb
Once you are logged on, you can use a similar approach to access the compute cluster.
