Research data: storage and backup on C&CZ fileservers
With the lower prices for network discs and backup, several departments have started the move from locally managed discs to backupped fileservers of C&CZ. In general this has big advantages for reliability, backup and access rights that can be mananaged by the department itself. Biggest disadvantage is that network discs that have to be backed up, have to be divided in projects or other chunks of max. ca. 400 GB. Departments interested in moving their data to C&CZ fileservers should contact postmaster. The current setup is based on Samba/NFS fileservers, C&CZ is investigating a new setup based on Ceph.

Departmental computers to Windows10
New departmental computers can be installed with Windows10 by C&CZ. Also existing pc's can get an upgrade from Windows7 to Windows10. You can make an appointment for this with the C&CZ helpdesk. After that, users can install software themselves with the catalogue of the Software Center. N.B.: the Outlook2016 installed with Windows10 doesn't work well with the Science IMAP mailserver. Alternatives: mailclients like Roundcube and Thunderbird or a different mailserver like the RU Exchange mail and calendar service.

Eduroam CAT to setup Eduroam
The ISC made setting up the wireless network simpler and safer by switching to Eduroam CAT. Employees and students of Radboud University are offered an installer tailored to the RU campus network. Eduroam CAT currently supports various versions of Windows, MacOS, OS X, Linux, Chrome OS, Android and a generic EAP configuration. In order to use Eduroam CAT, Internet connectivity is necessary. On campus, this might be the network Eduroam-config, but then one must use the RU-specific instructions

Digital testing/assessment with cloud application streaming
Since February 2015, digital tests/assessments can be held within the Faculty of Science.
Last week, more than 300 students Computing Science were successfully graded in a large scale digital test/assessment with use of the Netbeans integrated development environment. This IDE was streamed as a Windows application from cloud supplier Amazon. The application ran in a tab of the RU Kiosk App and was delivered through Amazon Appstream 2.0 on Chromebooks. The Chromebooks were purchased last year by the university to make large scale digital testing/assessment possible.

More privacy in Mailman lists
In the context of the new privacy legislation the default properties of all mailman lists have been modified.
- the mailman lists are no longer publicly announced on the mailman server.
- the members of a list can only be viewed by the list administrators.
- subscription to a list is restricted to addresses in ru.nl, radboudumc.nl and mpi.nl.
The third property is probably too restrictive for some of the lists, list administrators can revert this change in the privacy options (Ban list).

Webmail: Roundcube and Exchange alternative for small screens: Rainloop
For small screens of smartphones, the webmail of Roundcube is not very well suited. That is why there is an alternative now: Rainloop. You can set a "threaded view" in Rainloop, which is also handy for small screens. The Science addressbook is available in Rainloop. One can also use Rainloop for the RU Exchange mail. But Roundcube has many other advantages over Rainloop: manage folders shared with other users, shared labels and the administration of Sieve filters and out-of-office messages. For more information see our mail page.

Test of Ubuntu 18.04 on Linux login server lilo6
As a test of the new version of Ubuntu, 18.04 LTS, we have installed a new login server lilo6.science.ru.nl. In a few months it will replace the five year old login server lilo4. The name lilo, that always points to the newest/fastest login server, will then be moved from the two year old lilo5 to the new lilo6. The new lilo6 is a Dell PowerEdge R440 with 2 Xeon Silver 4110 CPU @2.10GHz 8-core processors and 64GB RAM. Because we enabled hyper-threading, it is showing 32 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.

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.
