Matlab R2018a available
The latest version of Matlab, R2018a, 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-R2017b/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.

Compute clusters move to Ubuntu 16.04
C&CZ installed a new head node for the cn-cluster with Ubuntu 16.04 and a new version of SLURM. This makes it possible to upgrade all cn-clusternodes to these versions. Other clusters (coma, neuroinf, mlp) had this upgrade already. The C&CZ-managed cn compute cluster consists of 60 nodes with 1560 cores and 8 TB RAM. The Astrophysics coma cluster, with 920 cores, 600 TB fileserver storage, GPU's and fast Infiniband interconnect is a separate cluster. For more info, see the cn compute cluster page.

Old Sopho telephone exchange switched off
After more than 30 years of loyal service, the old Philips Sopho S2500 telephone exchange of the SKU (RU and Radboudumc) has been switched off and removed. This 'first digital telephone exchange' was commissioned by FNWI in August 1987, as a pilot project of PTT, Philips and the RU (then KUN). Aad Hulsbosch of C&CZ was one of the driving forces during commissioning. In 1991, the Sopho switch was expanded for the entire SKU, to approximately 15,000 connections. The telephone functionality on the SKU has recently been completely taken over by an IP telephone exchange of Mitel Mitel and the Vodafone Wireless Office wireless telephony.

Donation to free and open source software: ISC, FSF and OpenBSD
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 of C&CZ. This year the Internet Systems Consortium, OpenBSD and the Free Software Foundation (FSF) were chosen. The Internet Systems Consortium develops a.o. BIND (DNS/nameserver) and ISC DHCP, both basic services of the network and the Internet. OpenBSD develops, next to OpenBSD itself, also OpenSSH and LibreSSL. The FSF supports GNU/Linux, which is used on almost all servers maintained by C&CZ and on many hundreds of workstations, including the computer labs.

Linux printing to Peage now simple
Initially as a test, there is now a much simpler alternative to the SMB printing from Linux. A printer "Peage" now is available on the Linux workstations and servers managed by C&CZ. The C&CZ print server translates the Science username to the U- or S-number and sends the print job onwards to a RU payprint server. Command line printing with the command lpr is also possible (lpoptions -pPeage -o SelectColor=Color to make color prints by default).

SURFdrive: now 250 GB per user
In SURF News we read that as of October 9, the storage space for users of SURFdrive has been expanded from 100 GB to 250 GB. SURFdrive is a Dropbox-like storage for work-related files, that should not have the security classification critical or sensitive. Data is stored within Dutch borders, the users remain the owners of their own data, and SURF itself provides no information to third parties, which makes SURFdrive more secure than Dropbox.

Replace FTP URL's by HTTPS
Because Chrome will label all FTP URL's as "not secure" starting December 2017, it is wise to change those URL's, if you offer files through ftp://ftp.science.ru.nl/pub. The same files can be found with the more secure URL https://ftp.science.ru.nl/.

Website certificates more secure with CAA in DNS
In all DNS zones C&CZ added DNS CAA Resource Records. As of September 8, 2017, we have more control over the SSL certificates for our domains. A hack at a random provider of certificates, like Diginotar in 2011 (Dutch only) can no longer be used to generate false certificates for our domains, because in the CAA records we noted that we only use certificates issued DigiCert.

Upgrade to Ubuntu 16.04 for Computer labs and individual workstations
During the summer break all computer labs will be (re)installed with Ubuntu 16.04 LTS. Since months ago, one can test course software using the Ubuntu 16.04 loginserver lilo5. All PC's in HG00.029, HG00.206, HG02.253, library, study landscape, project rooms and college rooms will be replaced by new ones, (All-in-One, dual boot with Windows7 and Ubuntu 16.04 Linux).
If you are using Linux PC's in computer labs as well as a managed Linux PC in your office, we advise you to consider upgrading your office PC to Ubuntu 16.04 as well. Running Ubuntu 12.04 or 14.04 in your office on a managed PC and using an Ubuntu 16.04 PC in the computer labs will result in problems.

print_mail_to_link('mail-address_Givenname.Surname', 'ru.nl_for_FNWI_staff_from_August_1')">Exchange account/mail-address Givenname.Surname@ru.nl for FNWI staff from August 1
Starting August 1, all FNWI employees who do not have an account yet in Exchange, the RU central mail and calendar, will get such an account and with that an extra mail address, of the form For anyone who already has an Exchange account, with a mail address ending in e.g. @ru.nl @donders.ru.nl @fnwi.ru.nl, nothing changes.
In Exchange one can share calendars with eachother, which makes making appointments easier. All new Exchange accounts will get a "redirect" to the current Science address. As a result, you will not miss an email: you only get an extra address, that redirects all new mail to the existing address.
Do you want to use Exchange? The "redirect" can be turned off by logging in to https://mail.ru.nl with your U-number preceded by "RU\" and your RU password. After that, you can remove the check box in "Options -> Create an Inbox Rule" at "redirect all incoming". Sending new Science mail to Exchange can be turned on by visiting the Do-It-Yourself Site and "forward" to the @ru.nl mail address.
Take Note 1: Thunderbird users should install the add-on Lightning to be able to see and process Exchange calendar requests.
Take Note 2: if there is a redirect line in Exchange, Exchange will not forward mails with sender address the same as the forwarding address, in order to prevent mail loops.
If you have questions, please contact C&CZ.

Sustainability: automatically switching off computers
If a department wants to switch off the C&CZ managed computers that are not currently in use after working hours and/or lunch break, then C&CZ can automate that. Please contact Postmaster. Since years already, the pc's in the computer labs, study landscape and Library of Science are being switched off after working hours and a few times per day when not in use. This mechanism is also used to automatically install the Windows and Ubuntu Linux updates during the night.

C&CZ reachable via Whatsapp/Telegram/Signal
If you do not have cellphone coverage, but do have an Internet connection, then you can reach C&CZ also via Whatsapp/Telegram/Signal on +31 6 15 35 26 77. The direct reason for this is that not in all wings of the Huygens building all mobile carriers have good coverage. However, the wireless Eduroam network has good coverae everywhere, which allows all staff and students to call C&CZ, independent of their mobile provider. Gradually, more providers will support Wi-Fi calling, which eliminates the need for an app like Whatsapp/Telegram/Signal for this purpose. Currently only Vodafone supports Wi-Fi calling, KPN has plans to introduce this in 2017.

Departments can order card readers for Peage
The RU Facility Services (Facilitair Bedrijf) let us know that if a department wants to speed up the use of the Konica Minolta multifunctionals, a department can order a campus card reader for € 300,-. After that, a staff member only has to type the PIN (4 digits) and swipe the campus card to login, just like students do on the ground floor of the Huygens building. Because a new European tender is expected to be finished January 2018, this will only be of interest for very busy multifunctionals.

Eduroam within RU firewall again
The ISC moved the wireless Eduroam network back within the RU firewall on the evening of May 22. In December 2015 it had been moved outside of the RU firewall because of firewall performance issues. The new firewall that is in place since December 2016 can handle much more traffic, therefore this move could be planned.

Poster printer service kamerbreed more reliable
The A0 photo printer kamerbreed, that C&CZ acquired free of charge in May 2013, printed many posters for staff and students. Lately there were several breakdowns, that took quite long to repair. That's why we decided to buy a new one, with warranty contract. In case of calamities we can switch to the old one. We expect that that makes the poster print service a guaranteed service for the next years, where we will not have to redirect customers to the RU copyshop.

Mentimeter for interactive presentations
Radboud University has a license for Mentimeter in the academic year 2016-2017. Possibly the license will be continued after that. Mentimeter is a tool to make a presentation interactive: listeners can vote anonymously with their phone, laptop or tablet on questions or statements. Feedback can be displayed immediately. Mentimeter resembles the older Shakespeak tool, but offers more functionality and is fully browser-oriented (does not work with a Powerpoint plugin like Shakespeak). Anyone with a mailadres within the RU domain can sign up.

New servers for home directories
The home directory/U:-disc servers pile and bundle, that are more than four years old, are being replaced by new servers with the name home1 and home2. Moving the home directories (U:-discs) of users is scheduled outside of working hours. Special arrangements will be made for groups of users who would be troubled by this, e.g. having Outlook .pst files on the network or using the compute cluster. During the move, the minimal quota for the Science home directory / U:-disc is enlarged from 2 GB to 5 GB. Workstations/PCs might need a reboot if successful login to Ubuntu proves to be impossible.

Phasing out outdated password encryption
For security reasons C&CZ will phase out an outdated, now considered unsafe, encryption type of Science passwords. Accounts that haven't changed their passwords since September 1, 2014, will be affected. The change will be carried out mid Februari 2017.
If you haven't changed the password of your Science account for several years, it is very likely that some services still use the old encryption type. Examples of these services are passwords used to login to Linux machines, Eduroam access by using your Science account or the Science VPN server. To continue using these services, the old encryption has to be replaced. This can be done by resetting your Science password at the Do It Yourself site. The menu item 'password' allows you to set your password. This page also shows a remark about when your password was last changed.

Do not fall for phone scam
Today we received messages from a few employees, that they had received cold phone calls from persons offering help with computer problems, or who told them that they could see everything the employee did on the computer. *Do not fall for this, do not answer their questions, do not take the actions they request.* In case of doubt, please refer them to C&CZ.

Computer lab HG00.137 renewed
During the Christmas break all PCs in the computer lab TK137 (HG00.137) have been replaced by new ones, of the same type as with the previous replacement. These are Dell OptiPlex 7440 AIO with 24-inch Full-HD screen, a Core i5 6500 (3.2GHz,QC) processor, 1x8GB memory, 512GB SSD hard disc and relatively quiet Cherry Stream 3.0 keyboards. For possible use with digital exams we have chosen the Dell Articulating Stand.

Donation to free and open source software
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 on which projects would receive a donation of C&CZ. This year the Free Software Foundation (FSF) and Limesurvey were chosen. The FSF supports GNU/Linux, which is used on almost all servers maintained by C&CZ and on many hundreds of workstations, including the computer labs. LimeSurvey is used for conducting surveys since 2008. Since the end of 2011, it is used for all ca. 500 course evaluations of the Faculty of Science per year. In addition, it is also used by departments (as PUC, ISIS and the Education Center) and individual employees and students of the Faculty of Science. For more info, see our LimeSurvey page.

C&CZ 3D print service
Several departments within the Faculty of Science have a 3D printer for their own use. At the TeCe there are two 3D printers with different techniques, to produce parts for Science experiments. Now C&CZ starts a 3D print service for staff and students of the Faculty of Science, primarily meant for use in education. For more details, see the Printers page.

Study associations: printbudget to Peage?
If student groups that still have C&CZ print budget let C&CZ know before mid December to which Peage accounts the budget should be transfered, this can be finished before the end of 2016. After that, the only option is to transfer the money with a one-time payment order to a bank account, which is less efficient. All FNWI Konica Minolta MFPs within the C&CZ-printbudget system have been switched to Peage. The C&CZ printbudget system is now only used for the HP printer escher (Library of Science), the posterprinter kamerbreed and the C&CZ 3D print service.

New OpenVPN alternative for old VPN that shuts down on Dec. 1
Because some Linux and MacOS users had problems with the new IPsec-based VPN and also with the existing alternatives, we setup a new OpenVPN service. The hope and expectation is that with this new service, we can shut down the old PPTP-based VPN.science.ru.nl, which is no longer considered to be secure, on December 1 as earlier announced.

RU network down Monday night Dec. 12 22:00-03:00
The ISC let know that the central RU network will be down in the night of Monday December 12 22:00 till Tuesday morning 03:00 because the RU firewall will be replaced. From 22:00 hours RU-central services such as Exchange (e-mail and calendar), BASS, Osiris and Blackboard will not be available. From 23:00 hours no traffic through the RU firewall will be possible, the RU will then be disconnected from the Internet. Internal wired FNWI traffic will not be hindered. Internal and external telephony will not be hindered too. If there are serious objections to this maintenance for ongoing research, one can contact us.

Test of Ubuntu 16.04 on Linux login server lilo5
As a test of the new version of Ubuntu, 16.04 LTS, we have installed a new login server lilo5.science.ru.nl. In a few months it will replace the five year old login server lilo3. The name lilo, that always points to the newest/fastest login server, will then be moved from the two year old lilo4 to the new lilo5. The new lilo5 is a Dell PowerEdge R430 with 2 Xeon E5 2630L v4 processors with 10 cores. Because we enabled hyper-threading, it is showing 40 processors. It has 64 GB of memory. For users who want to check the identity of this new server before supplying their Science-password to the new server: ECDSA key fingerprint is 7d:08:27:61:ac:c8:f1:05:4f:c9:91:2a:83:e5:c3:4f. Please report all problems with this new version of Ubuntu Linux.

Password hygiene: personal and not too old, just like a toothbrush
The RU has recently held a Treat your password like your toothbrush campaign. C&CZ too will act on old passwords: IT contacts will get a list of their users that have not changed their Science password in years. Old Science passwords do not have the most recent encryptions, therefore we would like to see them changed to remedy this. Even choosing a new Science password that is the same as the old one, helps to get rid of old password encryptions but please do choose a new password. Science passwords can be changed at the Do-It-Yourself website. When changing a password, please consider beforehand which (also private) devices will automatically keep on trying the old password, in order to prevent any inconvenience.

Matlab R2016b available
The latest version of Matlab, R2016b, 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-R2016a/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.
