We have updated the authentication process for login server lilo7 (lilo7.science.ru.nl) as part of a test. As of now, your ~/.ssh/authorized_keys file on lilo7 is ignored. This change is designed to prevent bad actors from easily gaining persistent access. The good news is that we can now grant access to lilo7 from outside the previously very restricted IP ranges. To gain access from a new IP range, you will need to provide us with your public SSH key and the IP range you will be connecting from....
The Science newsletter is sent from an @ru.nl mail-account. Recently, the @ru.nl mailservice was changed by adding Exchange Online Protection (EOP). EOP is the successor for Radboud University to the Proofpoint e-mail security filter. EOP added a mail header line to the newsletter List-Unsubscribe: https://c8ce19ec62454d21b73b7d5a25559d8f.svc.dynamics.com/t/lu/7... which made the mail appear to be spam to the Science spamfilter SpamAssassin. 1.1 URI_HEX URI: URI hostname has long hexadecimal sequence When we noticed this, we fixed it by welcome listing (allowlisting/passlisting) the sender address communications-science@ru....
After the Monday morning reboot, the NFS server on home1 refused to start properly. We are investigating why a manual restart of nfs was needed.
RU mail management let us know that yesterday the forwarding to external (non-RU) mail addresses has been stopped as announced earlier. Unfortunately, mail for several dozens of Science users was/is not forwarded to the Science mailservers. These mails can still be found in MS365 (RU mail), either in the Inbox or in the Deleted Items. RU mail management promised that the forwarding will be corrected tomorrow.

Our daily backup system relies on cephfs storage, which is currently offline, see CPK#1337. This means that as of July 22nd we are unable to perform or restore daily backups. When the cephfs problems are resolved the daily backups should also be OK and restorable again. NB, this has no effect on the Monthly backups, which continue to work normally.
After the power down of the Huygens building we are experiencing a problem with bringing Ceph file system back online. We currently do not know when the Ceph cluster is operational again. Update 2023-08-01 10:30 Ceph is working again. This CPK is now closed. CPK#1338 is also closed. Update 2023-07-31 12:30 After some more support from 42on, we managed to restart the cephfs, we cannot be sure all files are there, but almost all files are....
The VPNsec service will be moved to a new server. This move will cause downtime and existing VPN connections will be destroyed. Downtime is expected not to exceed several minutes.
Last friday, a change in the mailman configuration has been rolled out which had the inadvertent effect that mails were not delivered to external addresses anymore. However, these mailman posts were sent successfully to internal Science mail addresses. The change has been rolled back for the moment but is a necessity meaning that we’re looking for another solution.
The connecting router (dr-huyg) for all servers in the subnets 131.174.30.0/24, 131.174.31.0/24 and 131.174.16.128/26 will be replaced. It is expected that this will cause an interruption of ca. 10 minutes in the connectivity, but unforeseen circumstances may increase this delay. The reason to do this now is because of the planned power interruption on July 22. The old router hardware has a high probability of failing to survive this.
