In our continuous efforts to secure our national infrastructure, we have implemented a new feature in the CCDB whereby public SSH keys can be uploaded to your account and used to connect to our clusters (Cedar, Graham, Béluga and Niagara and Mist).
We have received positive feedback from the community.
SSH keys will be the only way to authenticate on Niagara and Mist starting January 24, 2022.
Important dates
Starting on November 1, 2021: Authentication on Niagara and Mist with SSH keys will only accept keys that have been uploaded to the CCDB. Keys that are only in .ssh/authorized_keys will no longer work.
Every Monday of November 2021: From 10:00AM to noon Eastern time, authentication on Niagara and Mist will only be possible with SSH keys. Authentication using passwords will be disabled.
December 1, 2, 3 and 6, 7 2021: From 09:00AM to 01:00PM Eastern time, authentication on Niagara and Mist will only be possible with SSH keys. Authentication using passwords will be disabled.
December 8, 9, 10 and 13, 14, 15 2021: From 09:00AM to 03:00PM Eastern time, authentication on Niagara and Mist will only be possible with SSH keys. Authentication using passwords will be disabled.
January 10-14, 17-21 2022: From 10:00AM to 05:00PM Eastern time, authentication on Niagara and Mist will only be possible with SSH keys. Authentication using passwords will be disabled.
From January 24, 2022: Authentication on Niagara and Mist will only be possible with SSH keys.
What you need to do
To learn about SSH keys, see the drop-in sessions on https://support.scinet.utoronto.ca/education/go.php/586/index.php/ib/1//p_course/586.
If you know how to use SSH keys,
- Create your SSH key pair from your workstation.
- Upload your SSH public key to your CCDB account by connecting to https://ccdb.computecanada.ca/ssh_authorized_keys. After a few minutes, you should be able to authenticate on Niagara or Mist
- If the .ssh folder in your $HOME directory contains a file named authorized_keys, it should be deleted.
- Log out of the cluster and log in again.
Additional documentation on usage and best practices is also available in SSH Keys
