New version of DIY.science.ru.nl
Today the new version of the C&CZ self service site DIY went live. This version also has a completely rewritten back-end, which allows new functionality to be added in the near future. The main new functionality that is available now, is the possibility of logging in with the Radboud ID (employee number or student number) in order to set a forgotten Science password. In case of questions contact C&CZ.

Shredding/destruction of data carriers / hard drives at C&CZ
The Internal Affairs department manages a contract with an external specialized company for the secure destruction/shredding of data carriers on location. The secure metal container that is used as a temporary cache, can be found at C&CZ as of the new academic year. Employees and students of the Faculty of Science can put data carriers with sensitive data in the container themselves at C&CZ. The C&CZ helpdesk can help recognizing and removing data carriers from desktops, laptops etc.

Because there was too much noise in the new rooms, C&CZ will temporarily move back to the third floor of the Huygens building. We expect that the final move to the ground floor will be in December 2022.

Test of Ubuntu 22.04 on Linux login server lilo8
As a test of the new version of Ubuntu, 22.04 LTS, we have installed a new login server lilo8.science.ru.nl. In a few months it will replace the four year old login server lilo6. The name lilo, that always points to the newest/fastest login server, will then be moved from the two year old lilo7 to the new lilo8. The new lilo8 is a Dell PowerEdge R6515 with 1 AMD 7502P 2.5GHz 32-core processor and 64GB RAM. Because we enabled hyper-threading, it is showing 64 processors. For users who want to check the identity of this new server before supplying their Science-password to the new server, see the section about our loginservers. Please report all problems with this new version of Ubuntu Linux.

Survey computer labs and BYOD
FNWI asks lecturers and students to fill in a survey about the computer labs. The reason is that the Faculty of Science plans to remodel its teaching rooms in a multifunctional way, with computer labs that use 'Bring Your Own Device' (BYOD). This means that the existing computer labs (terminal rooms, TK's) in the Huygens building will be phased out in the coming years. In order to plan the further implementation, we would like to request your input on the current use of the computer labs by means of a survey in order to determine the pace and which alternatives may be needed to replace the various current uses of the current computer labs. The project group will advise the Faculty Board based on this survey and the data from the actual use of the rooms and equipment (laptops and PC's).

Yearly backup during Christmas break
Just like every year during the Christmas break, in the next weeks a full backup of many servers/filesystems onto tape will be made, that is preserved a long time. This will have the effect that servers will sometimes react slower during this period.

Ceph data storage expanded
Since the end of 2019, C&CZ offers Ceph as a choice for data storage, next to the traditional RAID storage on individual fileservers. Because demand for Ceph storage is rising, the Ceph storage has been upgraded from 1.8 PiB to 2.8 PiB gross. With this upgrade, storage servers have been placed in a central RU datacenter, so the Ceph storage is now distributed over three datacenters. If you want to try whether Ceph suits you, please contact C&CZ.

BitTorrent traffic will be blocked
Because BitTorrent is considered to be a security risk (malware/reputation damage) and the traffic primarily consists of illegal downloads, the RU Security Operations Center (SOC) proposed to block this type of traffic from the RU network. Should this cause problems for research or education, we would like to hear from you, so we can notify the SOC and perhaps request an exception.

Donation to free and open source software: Mozilla
For the majority of the services C&CZ uses free software and open source software. Therefore, some time ago the idea emerged that the C&CZ employees would vote each year which projects would receive a donation from C&CZ. This year the Mozilla Foundation was chosen. Many people will know the Mozilla Firefox webbrowser and the mailclient Mozilla Thunderbird and maybe use it hours a day. But the Mozilla Foundation does a lot more to try to ensure the internet remains a public resource that is open and accessible to us all.

FNWI network cable administration by ISC networks
As of October 11, 2021, C&CZ will transfer the management of the fixed data connection points (network outlets, switch ports) in the Faculty of Science buildings (Huygens, Mercator, HFML/FELIX, Goudsmit, Proeftuin) to ISC networks. This concerns both activating/deactivating an outlet (patching) and adjusting settings or solving malfunctions. Taking care of the IP addresses (DNS/DHCP) and the shielding/security by means of Access Control Lists will remain with C&CZ. All requests and malfunctions relating to data connection points can therefore be addressed to the Helpdesk of the ISC as of October 11, by mail to or by telephone to (024-36) 22222. There is also a possibility to report a malfunction via a web form, see www.ru.nl/ict.

AVS Science now part of AVS Radboud
As of October 1, the Science AVS will be merged with Radboud AVS. This reorganization is a result of the improvement programme of facility management and real estate, with bundling of similar services on campus. This bundling creates a campus-wide AV service that will be controlled in its entirety by Campus & Facilities. For FNWI users, the existing contact options (email, telephone) and availability of local support will be continued for the time being in accordance with the existing situation. There will be further communication about any changes in the future. The AVD Faculty of Science resorted under C&CZ since January 2018.
