You may need to delete old entries on your ~/.ssh/known_hosts after the session to make sure the new host keys are added, but after that you should not need to do this again. For example, you may use the following command to remove the entries for hpc-login:
| No Format |
|---|
ssh-keygen -R hpc-login |
A similar command may be run for other hostnames with the same problem. After that, a new connection should prompt you to accept the new key.
We will also take the opportunity to make available the cron service on the hpc-cron node. Any tasks that need to be added into a crontab should be placed on this node. In case of node failure or system session, those crontabs would automatically be moved to another node.
