On 2022-08-10 we have planned a system session to set up the same ssh key across the 4 complexes using the current ac-login node as a master key. This change addresses addressed the issue of ssh errors when connecting regarding host key changes for a given host after an update, such as:
...
You may need to delete old entries on your ~/.ssh/known_hosts when connecting after the session to make sure the new host keys are added, but after that you should not need to do this again thereafter. For example, you may use the following command to remove the entries for 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.
Cron service
The We will also take the opportunity to make available the cron service on the hpc-cron node and ecs-cron node. Any tasks that need to be added into a crontab should be placed on this nodeone of these nodes. In case of node failure or system session, those crontabs would automatically be moved to another node.
