PCs in Study Area and Library of Science

Since the summer of 2021, the computers in the Faculty of Science Study Area (HG00.201) and the Library of Science (HG00.011) are no longer being managed by C&CZ, but by the ISC (RU ICT Service Centre). That makes all Windows computers in all RU Study Areas and Library locations uniform. Technical contact now is is the ICT Helpdesk: 024-3622222, . General information about the Library of Science (such as opening hours and reservation of a study place), can be found at the Library of Science website.
In addition to these Windows-only computers, eight Linux-only computers, that are managed by C&CZ, are available in the front of the Study Area (HG00.201).

Expansion of Science datacenter to Forum building

Because FNWI research groups are increasingly purchasing powerful computers/computing clusters with many CPUs and GPUs, C&CZ has expanded the data center to the existing server room of Radboud Services, in the Forum on the other side of Heijendaalseweg. As a result, there will be sufficient physical space, power and cooling for the servers purchased by departments in the coming years.

New version of Mathematica (12.3.0)

A new version of Mathematica (12.3.0) has been installed on all C&CZ managed Linux systems, older versions can still be found in /vol/mathematica. The installation files for Windows and Linux can be found on the Install-disk, also for older versions of Mathematica. Departments that take part in the license can request installation and license info from C&CZ.

Mailman lists sender address change: from sender to list address

DMARC is increasingly being used as a spamfilter, checking whether the sender ought to send mail via this route. To comply with this for mail sent through Mailman, we will change the From: sender address to the list address. The current:

> From: Some User <>
> Sender: "listname" <>

will be changed to:

> From: Some User via listname <>
> Reply-To: Some User <>
> Sender: "listname" <>

If you filter or forward mail automatically, you might need to change the filter.

Linux login server lilo5 decommissioned

The support for Ubuntu 16.04 LTS ends on April 30th, 2021. Therefore we will turn off lilo5 with this version of Ubuntu on May 1st, 2021. The default login server (lilo.science.ru.nl) points to lilo7 with Ubuntu 20.04 LTS, but lilo6 with Ubuntu 18.04 LTS will remain available until support for this version ends in 2023. The signatures of the C&CZ loginservers can be checked. Please also check these tips for improving your SSH settings tips for improving your SSH settings.

Maple new version: Maple2021

The latest version of Maple, Maple2021, can be found on the Install network share and has been installed on C&CZ managed Linux computers. License codes can be requested from C&CZ helpdesk or postmaster by departments that take part in the license.

Windows 7 computers disabled in B-FAC domain

Because of security issues the last remaining Windows 7 machines wil be disabled, effective 24-03-2021, as member of the Active Directory Domain B-FAC. Please upgrade these computers to a more up-to-date OS. See also previous announcements on Windows 10 and the end of Windows 7.

Matlab R2021a available

The latest version of Matlab, R2021a, is available for departments that have licenses. 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-disc. All C&CZ-managed Linux machines will soon have this version installed, an older version (/opt/matlab-R2020a/bin/matlab) is still 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.

Signed SSH keys for loginservers and compute clusternodes

From now on, C&CZ signs the SSH keys of e.g. loginservers and compute clusternodes. That makes it possible for users, as explained on that page, to add the public signing key in the private .ssh/known_hosts, which makes one trust all C&CZ signed SSH servers. Whenever C&CZ deploys a new 'lilo', the question whether this might be spoofing will not occur then.

Site license for Gaussian 16 and GaussView 6

Organic Chemistry purchased a site license for the use of Gaussian 16 and GaussView 6 with the GMMX Module on Linux. The software has been installed on the cn-cluster. Departments that want to use this, can contact Prof. Jana Roithova or Postmaster.

Major RU network maintenance Saturday Feb. 27 08:00-20:00

The ISC announced that Saturday February 27 08:00-20:00 major RU network maintenance work will be carried out. This will mean that all RU services will be unavailable several times for at most an hour. This concerns all RU services including those of FNWI/C&CZ: e-mail, VPN, wifi, BASS, OSIRIS, Brightspace, Syllabus+, Corsa, etc.

End of Science OpenID service

The Science OpenID-service, that was introduced in 2007 as authentication method for the wikis managed by C&CZ, will be terminated March 1, 2021. All wikis will be switched over to a more modern authentication method via SAML.

New improved installation methods for Matlab

The old installation method, used with Matlab R2020b, highlighted several problems for some users. The solution was found in a different installation method. Some users will prefer the new method, others the old one. Each has its pros and cons. The new installation method makes Matlab easy to install, also for older versions and can be done with a small download if you only want a few toolboxes. But it requires signing in at The MathWorks and thus has a more complex workflow. The old installation method does not require registration and has an easy workflow, but it always requires a large download and non-expert macOS users will find it troublesome because the newest macOS version will quarantine the download.
