Due to a phishing attack targeting science accounts, and the subsequent abuse of RU mail servers to sent out spam and phishing from valid science e-mail accounts, we were forced to employ a set of defensive measure as evident from cpk/1381, cpk/1382, cpk/1381. To prevent further abuse (and disruption) caused by compromised accounts, we have had to temporarily restrict access to some science services. These services include: Anything related to e-mail: Roundcube, authenticated SMTP, IMAP, and POP3....

C&CZ has been working to replace the current DIY website to make it easier to add new functionality to it. This work included a rewrite of the website and a large part of our tooling to the Go language. Taking the Dutch term for DIY (Doe Het Zelf - DHZ) prefixing it with Go, this resulted in the codename “godzilla”. A pre-release of this new website is running on https://godzilla.science.ru.nl. Note this site is fully functional (modulo bugs), so any changes made there are really being made to your science account....

The Science VPNsec and OpenVPN service will be discontinued as of 2024-12-01 (1 Dec 2024) 2024-11-26. To ensure continued secure access to our network, we recommend transitioning to eduVPN, our officially supported VPN service. This was first announced in February 2024. If you have any questions or require assistance, feel free to contact us.

A new version of Mathematica (14.1.0) has been installed on all C&CZ managed Linux systems, older versions can still be found in /vol/mathematica. When connected wired or wireless on campus or through VPN, the software for Windows, Linux and macOS can be found on the C&CZ Install disc. During the installation you must specify: License server: mathematica.science.ru.nl License: L4601-6478 According to the Mathematica Quick Revision History: “Version 14.1 introduces the unified Wolfram application and expands Wolfram Language by offering new tools for working with neural nets and LLMs, for finding differences in content, for working with images and videos, and for exploring scientific evaluations through biomolecules, astrophysics and more”

Recently, the Radboud news reported that students can have small repairs to their laptops done in the RUpair-shop without any labor time being charged. For students and employees of FNWI, the C&CZ helpdesk provides a similar service. Stefan Reijgwart and Dominic van den Broek in particular are specialists in repairing laptops, among other things.

The latest version of Matlab, R2024b, is available. The software and license codes are directly available for Science accounts and can be requested by other entitled users by sending mail to the helpdesk. The software can also be found on the install-share. All C&CZ-managed Linux machines have this version installed, the older version (/opt/matlab-R2024a/bin/matlab) will be available temporarily. The C&CZ-managed Windows machines will not receive a new version during the semester to prevent problems with version dependencies in current lectures....

The Science mailservice used Spamhaus for decades as one of the blocklists to filter spam in mail. When we were notified that we would need a commercial license that would cost ca. 5kEUR/y, we investigated how much more spam would come through without the Spamhaus service. This showed that users would get more spam, but most of it would be delivered in the Spam folder. Next to that, we expect that the spam filtering of the also used Exchange Online Protection will improve....

All license info, including the license codes, are now readily available for all Science users at the Science license overview page for the Science software managed by C&CZ.

After the storage downtime of CephFS in our Ceph cluster, we decided together with the users of this service to stop offering CephFS shares through SMB and NFS. All data has been copied out of CephFS. We have ended the CephFS service. We will only use the Ceph cluster to store our backups, using the S3 API.

The latest version of Matlab, R2024a, is available. The software and license codes can be obtained through a mail to postmaster for those entitled to it. The software can also be found on the install-share. All C&CZ-managed Linux machines have this version installed, the older version (/opt/matlab-R2023b/bin/matlab) will be available temporarily. The C&CZ-managed Windows machines will not receive a new version during the semester to prevent problems with version dependencies in current lectures....
