C&CZ Problem Card

Several parts have been replaced. We assume the problem, that occurred twice, is now resolved. For dual-boot pcs, the boot menu was served by an alternative method during the repair.

Affected : Users of Science VPN and Eduroam based on science account The certificate of the LDAP servers has been replaced this morning, this has also changed the certificate chain. The radius server uses LDAP as authentication backend and in the radius configuration the certificate chain had to be changed too. This was initially overlooked. Radius is the authentication mechanism used by all VPN servers and Eduroam

The server went down in the same way as the previous time (3rd of June 2020). The cause is most likely a system board problem. This part will be replaced Tomorrow by a support engineer.

by a website) and various websites. The server couldn’t be reached after the scheduled weekly reboot, not even on its management interface. Because also C&CZ employees work from home and the interruption didn’t get enough urgency fast enough, the interruption lasted too long, apologies for that. The support partner has been contacted and the server has been updated, but the origin of the problem is still unclear. We will also look at making these services more redundant or more easily movable to a different server....

Due to a failed BIOS upgrade, the hardware of the database server appears to be bricked. We transfered the disks to another machine (cn00) and all database services are now up again, at the cost of not having cn00 running. When the hardware is working well again, we will swap it all back and restore the original situation.

Due to performance tuning having gone wrong the jitsi.science.ru.nl conference rooms cannot be joined by more than one person at the moment. Solved by reinstalling server.

The new certificate of the Science mailserver hadn’t yet been placed in the right place. The expiration of the old certificate caused a problem for Science mail users, that was resolved by replacing the old certificate.

March 25, a rule “2020 Radboud Universiteit” was added to the Science spamfilter. Recently, this matched RU-central mailings. Therefore RU-wide mailings from e.g. the RU Board and Radboud Recharge have erroneously been delivered in the Spam folder of Science emplyees. The Science spamfilter tries to fight spam and phishing, this is partly manual work in which errors can’t be excluded. C&CZ apologizes for the inconvenience this has caused.

A critical security update for GitLab has been released and is being installed this moment. During the update, GitLab is offline.
