Enforcing Two-factor Authentication on NEMO

Published: 11 Oct 2023 by NEMO Team

UPDATE 21.11.2023: We will enforce 2FA logins on login2 on 29.11.2023 and on login1 11.12.2023.

UPDATE 13.11.2023: We will inform you in the next few days when this will be the case. We need to fix a problem first.

UPDATE 03.11.2023: We will enforce 2FA logins on login2 on 13.11.2023 and on login1 2 weeks later on 27.11.2023.

As previously announced, we are testing 2FA for logins on NEMO. This feature will be enforced on all login nodes on NEMO in November. We will enforce 2FA logins on login2 on 06.11.2023 and on login1 2 weeks later on 20.11.2023.

If you want to test your login, please use vis1.nemo.uni-freiburg.de and vis2.nemo.uni-freiburg.de. If you need a SSH login without a second factor, please contact us (Support NEMO).

Please visit https://login.bwidm.de/user/twofa.xhtml to create a new token if you don’t already have one. If you have already generated a second factor for bwUniCluster or JUSTUS2 on https://login.bwidm.de, you are good to go. See https://wiki.bwhpc.de/e/Registration/2FA for more information.

The AMD Genoa, Machine Learning and AI partitions for NEMO2 were delivered on December 4th. The acceptance of the storage has been delayed, so that NEMO2 could not yet start this year. However, calculations with the Milan nodes in NEMO1 are still possible.

The Genoa partition for NEMO2 will be delivered on December 4th, at the same time all old NEMO1 nodes will be removed. To ease the transition, some new Milan nodes will be booted into NEMO1 environment and will remain available until at least January 31st. Users are encouraged to switch to the new Milan nodes and use the ‘milan’ queue for their jobs (-q milan). If demand increases, additional nodes will be added next week. The launch of NEMO2 is delayed due to unavailable storage, with further updates on testing and data transfer to follow once it becomes available.

The Weka Storage and Milan partition have been successfully delivered for the new NEMO2 cluster. Testing, benchmarking, and system configuration will take place in the coming weeks. We anticipate starting with limited functionality and gradually expanding it over time. A portion of the old NEMO cluster had to be shut down to accommodate the installation of the Milan partition.
