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.

New version of OriginLab (2015, 9.2)
A new version (2015, 9.2) of OriginLab, software for scientific graphing and data analysis, can be found on the Install-disk. The license server has been upgraded to this version. Departments that take part in the license can request installation and license info from C&CZ, also for standalone use. Installation on C&CZ managed PCs still has to be planned. Departments that want to start using OriginLab should contact C&CZ.
Ben Polman 24 sep 2015 11:49 (CEST)
Matlab R2015b available
The latest version of Matlab, R2015b, 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-R2015a/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. The R2015b release is the last version for 32-bit Windows. R2016a will support 64-bit Windows, but not 32-bit Windows.
Peter van Campen 21 sep 2015 17:07 (CEST)
Maple new version: Maple2015
The latest version of Maple, Maple2015, is available as of today on all C&CZ managed Linux PC's and will be available shortly on all Windows PC's. The license of Maple is a 5-user license. Of these, 4 are financed by the Faculty of Science departments EHEF and THEF. Because 1 license is paid by C&CZ, all FNWI employees and students are allowed to use Maple once in a while. If you want to use Maple more often, please contact C&CZ. The software can be found on the Install network share. License codes can be obtained from C&CZ helpdesk or postmaster.

Wireless network FNWI much improved in coverage and capacity
In the past months, the number of wireless access points in the Huygens building, Mercator 1 and HFML has been much increased, from 97 to 219. Almost all of these access points also support the new 802.11ac standard. This has much improved both coverage and capacity of the wireless network 'eduroam' in these buildings. To make sure that both coverage and capacity is optimal in important locations, the ISC will take measurements in the next weeks. We also ask users within FNWI that still have problems with the wireless network, to report this to the C&CZ helpdesk (). Where necessary, adjustments will then be made. More information about the wireless network can be found at the ISC website. The other FNWI buildings will get an upgrade in 2016, if budget is available.

Wireless network ru-guest will be replaced September 10 by eVA
As of September 10, the wireless network 'ru-guest' will no longer be available. Guests of Radboud University can now use the wireless network 'eduroam' through 'eVA' (eduroam Visitor Access). All employees and students of FNWI can request one or more eVA guest accounts at the C&CZ helpdesk (). When requesting eVA accounts please supply your mail address and your mobile number. More information on eVA can be found at the SURF website.

ArcGIS 10.3.1 available
A campus license of ArcGIS 10.3.1 is available. ArgGIS is being installed on all pcs in the computer labs. On request, it can be installed on managed Windows 7 pc's as well. Setup files and installation instructions are available on the Install network share for home use by students and employees. Home users need to setup a VPN connection in order to reach the license server.
Bram Daams 7 aug 2015 16:58 (CEST)
The most recent version of Microsoft Windows, 10, is available on the Install network share. The license permits upgrade to this version on university computers. License codes can be requested from C&CZ helpdesk or postmaster. For privately owned computers you can order this software relatively cheap at Surfspot.

Information session: "Onderwijs in Beeld" becomes "Weblectures"
Monday June 29, from 12:30 to 13:30 (sharp), in LIN1 (Linnaeus building).
We hereby cordially invite you to the information session about the new weblectures system which will become operational at the Faculty of Science in September 2015. This new Radboud University service will replace the current Onderwijs in Beeld system for recording lectures and viewing the recordings. In a presentation we will zoom in on what this means for you: what will change for students and lecturers and what are the new features when your course is recorded.
We hope to see you on Monday June 29.
See also the information site on weblectures (log on with your u-number).
With kind regards, Anna Galema (Weblectures functional manager) and Peter van der Wolk (Coordinator weblectures Mediatechniek)

Computer labs: upgrade to Ubuntu 14.04 and renewal HG00.075
During the summer break all computer labs will be (re)installed with Ubuntu 14.04 LTS. Since months ago one can test course software using the Ubuntu 14.04 loginserver lilo4. All PCs in TK075 (HG00.075) will be replaced by new ones, type HP EliteOne 800 G1 (All-in-One, i5-4570S Core, 2.9GHz, 8GB, 23 inch widescreen LCD monitor, sound), dual boot with Windows and Linux (Ubuntu).

New version of Mathematica (10.1.0)
A new version of Mathematica (10.1.0) has been installed on all C&CZ managed Linux systems, older versions can still be found in /vol/mathematica. The installation files for Windows, Linux and Apple Mac 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.

Watch out! Scammers send mail on behalf of Ziggo
Since a couple of weeks, people receive e-mails that seem to be sent by cable company Ziggo, but which in reality are phishing mails, sent by Internet criminals. The subject of the email is "Uw betalingstermijn is verstreken" (Your payment has expired). The e-mail suggests that the recipient has an invoice open and threatens with collection costs. The purpose of such a fraud is to persuade the recipient to click on a link or open an attachment. For more information about this particular scam, see dichtbij.nl. This time it's fake e-mails on behalf of Ziggo, but other crooks are active too. A useful website that provides information on scams is fraudehelpdesk.org.

MS Visio and MS Project license ends
MS Visio and MS Project are no longer part of the previously announced new agreement 2015-2017 between SURFmarket and Microsoft. Both Visio and Project have a grace period of 1 year, which means that previously installed versions of these products may be used until the end of 2015 at no additional cost. To avoid surprises by January 2016, C&CZ will already remove Visio and Project from C&CZ Managed pcs at the end of July, during the summer break.
Wim Janssen 19 mei 2015 17:12 (CEST)
Recently C&CZ hears from users that they receive mail from mail addresses they know with subjects like "You have a new notification from ... View?" or "... is waiting for your response. Respond?" or "I would like to add you as a friend". Accept?" The link (URL) in these mails points to something in "flipmailer dot com" or "infoaxe dot com". Clicking the link results in the installation of a spyware plugin/add-on/extension in the browser Firefox/Chrome/... If you fill in your mail-password on their website, all your contacts will get the same fake invitation. Do not fall for this! If you have responded to these mails, please contact the C&CZ helpdesk or search the Internet what to do to remove the spyware, such as deze how-to-remove-fliporainfoaxenet-spam-extension.

Linux login server lilo will point to lilo4
The name lilo, that always points to the advized login server, will be moved on Wednesday May 6 from the more than three year old lilo3 to the newer lilo4. This is a small step in the upgrade to Ubuntu 14.04. During the summer break the computer labs will be (re)installed with Ubuntu 14.04 LTS. Please remove the old entry of lilo(.science.ru.nl) from your ~/.ssh/known_hosts file. For cautious people wanting to check the fingerprint of the public RSA key before supplying their Science-password to the new server: aa:ad:c0:2e:60:9d:d3:cd:ca:a4:59:7d:d0:d8:4c:68. The name stitch for the second loginserver, that can be used if there is a problem with lilo, will be moved on May 6 to the older lilo3.

Eduroam with username without @ will end April 28
As of April 28, it is no longer possible to use the wireless Eduroam network with only a U- or S-number as username, without appending the domain @ru.nl. Until then, this works, but only on RU campus, because the RU RADIUS server then assumed the RADIUS realm @ru.nl. When one uses a username with a RADIUS realm like @ru.nl or @science.ru.nl, one can use Eduroam at all Eduroam connected institutions. How to add the RADIUS realm @ru.nl to your Eduroam settings can be found in the ISC announcement.

Matlab R2015a available
The latest version of Matlab, R2015a, 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. The C&CZ-managed 64-bit Linux machines will soon have this version installed, an older version (/opt/matlab-R2014b/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.

Lowering printing prices
Printing prices, for black&white als well as color, have been lowered, in accordance with the campus-wide printing prices. Reason for this reduction in cost is the fact that the total number of pages printed at Radboud University exceeded expectations and also that the fixed costs for the printing infrastructure were less than estimated beforehand. See also our printing information page

Renewal WiFi network Huygens and Mercator 1
During the period between March 23th and April 20th 2015, the WiFi network (Eduroam and RU-guest) will be renewed in the Huygens building, its surroundings and in Mercator 1 (floors 0-4). All existing access points are going to be replaced by a new type and the number of access points will be expanded to increase the bandwidth, coverage and capacity. The work involved will be performed by JS Network Solutions, commissioned by the ISC and under the direction of the UVB. Although the employees of JS will work mainly in the corridor areas, access to some offices and/or labs is necessary, of course after consulting the residents, secretariats and lab-managers. The work will start in Huygens wing 1 towards wing 8 and will finish in Mercator 1. The renewal of the WiFi network in the other faculty buildings is expected to take place in 2016. For further information, please contact Marcel Kuppens.

IMAP mail server upgrade next monday night
Begin : 20150216 23:00 End : 20150217 07:30 Affected : all users wanting to read Science mail
The IMAP server will be replaced by a new server next Monday night. During the night, no Science mail can be read from the server, because then the most recent mails will be synchronized to the new server. Mail can be sent in this period, but new mail will start being delivered on the new server from 07:30. A word of warning, one could login on the old server with the first 8 characters of the password, the new server only accepts the full password.

Apple Mac-software: Office 2011 SP1 and ATLAS.ti
For Apple Macs there is a new (SP1) version of the Microsoft Office 2011 software and a first version of the ATLAS.ti Qualitative Data Analysis software available on the Install network share. License codes are available from C&CZ helpdesk or postmaster. According to the site license, this software may be installed on all computers owned by the RU without additional costs. For home use of this software, staff and students can visit SurfSpot.
Peter van Campen 21 jan 2015 13:12 (CET)
Adobe Creative Cloud software
Adobe Creative Cloud is the successor to Creative Suite. The Adobe Creative Cloud software is available on the Install network share. License codes are available from C&CZ helpdesk or postmaster. According to the site license, this Adobe Creative Cloud for Enterprise (Specified Apps Only Non-Video) may be installed on all computers owned by the RU without additional costs. For home use of this software, staff and students can visit SurfSpot. The software consists of the following components: Photoshop, Illustrator, InDesign, Dreamweaver, Muse Pro, Acrobat Pro, Bridge, Encore, Fireworks, Flash Builder Premium, InCopy, Media Encoder, Edge Animate, Edge Code (preview) and Edge Reflow (preview).

Maple license continued as 5-user license
The license of Maple has been continued as a 5-user license. Of these, 4 are financed by the Faculty of Science departments EHEF and THEF. Because 1 license is paid by C&CZ, all FNWI employees and students are allowed to use Maple once in a while. If you want to use Maple more often, please contact C&CZ.

SURFdrive: safer than Dropbox
The ISC has announced that SURFdrive is available for RU employees. This gives a maximum of 100 GB of 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. Earlier SURF made SURFfilesender available, with which you can send larger files more secure than with alternatives like WeTransfer.
Peter van Campen 15 jan 2015 00:04 (CET)
Maple license temporarily continued
The license of Maple has been temporarily continued with a 5 user license. This gives IMAPP and C&CZ some time to find other departments that are willing to contribute financially to such a license. This would cost 900 € per year excl. VAT. Interested? Please contact C&CZ.

Total Vodafone coverage in Huygens with first Ericsson Radio Dot in the world
Coverage for mobile phones on the Vodafone network, as used for Vodafone Wireless Office has been extended to the basements and transport corridors of the Huygens building. This became possible, because Ericsson and Vodafone were interested in doing a pilot in the Huygens building with the first live enterprise deployment of the Radio Dot system worldwide. This is in addition to the distributed antenna system built in 2011, which was necessary because of the similarity of the Huygens building with a Faraday cage. This reminds some veterans of June 1987, when a pilot was carried out at the Faculty of Science by PTT (now KPN), Philips, SURF and the university with the first PABX with a large amount of data traffic in The Netherlands. This PABX is still in use for speech phone calls in the periphery of the Huygens building.

Student.ru.nl and fnwi.ru.nl mail also accessible through Roundcube
During the weekend of November 12, 13 and 14, the ISC will move the mail of @student.ru.nl from the old RU Share service to the new RU Exchange service. This can be accessed with a browser via RU Exchange webmail, but also via C&CZ Roundcube webmail, by choosing mail.ru.nl in the drop-down menu. Advantages of Roundcube are that you can set multiple sender addresses (via Settings->Identities) and that the Science LDAP addressbook is available, which contains all Science staff and students. The RU Exchange AD address book has very little FNWI scientific staff. Furthermore Roundcube has a more powerful and modern interface independent of the browser used. You can also leave out the extra RU\ before the U- or S-number when logging in. A disadvantage w.r.t. the standard Outlook Web Access might be that Roundcube does not have calendar support, it is only an IMAP mailclient.

Notice of change in Microsoft licenses as of 2015
The ISC let us know that by January 1, 2015 there will be a new licensing agreement with Microsoft through Surfmarket. The main difference appears to be that the license for Microsoft Office on Windows PCs owned by the University, will be followed by a license for Office 365 Plan E3 (formerly A3) for all RU staff. This will most likely mean that installing Office on Windows PCs and iPads/iPhones that are private property of RU staff will be possible under the license as of January 1, 2015. More information will follow in the first quarter of 2015.

Again phishing mails: "WAARSCHUWING" by "Admin"
In the past few days, a dozen students and staff of the Faculty of Science fell for a phishing email again. In broken Dutch the email stated that the mailbox was almost full. The subject often was "WAARSCHUWING" and the sender called himself "Admin". The mail contained a link to a counterfeit Science webmail page hosted by http://www.heliohost.org/ , a provider of free websites. On this website everybody could read the login names and passwords of everybody who reacted to the phishing email. C&CZ has blocked these logins and asked the sysadmins of HelioHost to remove the website. Do not fall for phishing emails, it causes inconvenience to yourself and others!

Disks xpsoftware and xpcursus renaming to software and cursus
The network shares xpsoftware and xpcursus, that many PC's use, have been renamed to software and cursus. The old names still work until Monday, January 5th 2015. These disks are also mounted as software share S-drive and course software share T-drive on PC's managed by C&CZ. Lecturers can manage their course software on the T-drive themselves.

End of SHA-1 certificates
All SHA-1 certificates of C&CZ managed servers will be replaced by new SHA-2 certificates on short notice. This is necessary because SHA-1 is no longer considered secure enough for the future. The Chrome browser will display a warning as early as November 2014 at a website with a SHA-1 certificate, other browsers will follow later.
Ben Polman 13 nov 2014 12:03 (CET)
End of SSLv3 protocol
Because of vulnerabilities in the SSLv3 security protocol, C&CZ has switched off support for this protocol on all C&CZ managed web servers. A secure connection will thus use the successor protocol TLS. Browsers like Chrome, Internet Explorer and Firefox will each sooner or later stop supporting SSLv3. There is information on how to manually adjust settings to eliminate the vulnerabilities immediately. This can however lead to problems with websites that need SSLv3, such as BASS. P.S.: as of mid-December BASS can be used without SSLv3.

Old aliases for mailserver will be removed December 1
C&CZ will remove the aliases for imap, imap-srv, imap-server, pop, pop-srv, pop-server, smtp, smtp-srv and smtp-server for domains cs , math, nmr, sci and theochem as of December 1. The automatic configuration of mailclients only uses post.science.ru.nl and smtp.science.ru.nl , as one should do when manually configuring a mailclient. Since the certificate of the mailserver is not valid for these old aliases, it raised security questions.

Terminal server ts2 and print server drukker from NWI to B-FAC
Due to decommissioning of the NWI.RU.NL Active Directory domain, on November 16 the terminal server ts2 and the printer server for departmental printers drukker will be moved from NWI.RU.NL to B-FAC.RU.NL. This change is of consequence for logging on to the terminal server ts2 and for connecting to printers from the print server drukker.
If you are logging on to the terminal server ts2 using NWI\loginname, you will have to change this to B-FAC\loginname. In the case of the print server drukker, if connecting to printers using \\drukker.nwi.ru.nl\printername, you have to change this to \drukker.b-fac.ru.nl\\printername. The easiest way to do this is to remove and reconnect the printer from the server.

Email addresses and passwords captured
The CERT-RU has sent a warning mail to the 600 ru.nl mail addresses that were in the list of 1.3 million captured Dutch accounts. That ru.nl mail address has apparently been used as a registration address in some website, that has been hacked. You must assume that passwords that have been used in such a hacked site are now known to Internet criminals. Therefore, you should never use that password anywhere again. Furthermore, everyone is advised to use different passwords for different websites/applications. Often you do not even have to remember these passwords, as they can be easily reset. In other cases, you can use a password vault such as KeePass, which is available for Windows, Apple, Android and Linux.

Matlab R2014b available
The latest version of Matlab, R2014b, 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. The C&CZ-managed 64-bit Linux machines will soon have this version installed, an older version (/opt/matlab-R2014a/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.

Secure network for vulnerable pcs attached to equipment
Often PCs attached to expensive measuring equipment do not get software updates, because the risk is too high that afterwards there is a problem with the equipment. In those cases C&CZ network administration can help by isolating the PCs on a separate shielded network, with specific rules for the network traffic allowed to and from that network segment. It is possible to write data to a network drive, that can be read (but not written) from other locations. Also traffic to the C&CZ printer server can be allowed, so no local printer is necessary. Departments such as Microbiology, HFML and FELIX have been using this shield for years. A recent vulnerability that is a huge risk for for Linux systems without software updates, is Shellshock. Windows systems will be very vulnerable unless they have the Microsoft patches that are published on Patch Tuesday.

New version of OriginLab (9.1)
A new version (9.1) of OriginLab, software for scientific graphing and data analysis, can be found on the Install-disk. The license server has been upgraded to this version. Departments that take part in the license can request installation and license info from C&CZ, also for standalone use. Installation on C&CZ managed PCs still has to be planned. A new maintenance contract untill August 2017 has been signed with the supplier.

Temporary computer lab in HG00.625/629
Due to the increased number of students, a new computer lab will be realized in HG00.625/629. This space becomes available through the relocation of FEZ to Mercator 1, fourth floor. Because no decision has been made about the final layout of wing 6, a temporary facility will be realized. There will be 42 student and one instructor PC, type HP EliteOne 800 G1 (All-in-One, i5-4570S Core, 2.9GHz, 8GB, 23 inch widescreen LCD monitor, sound), dual boot with Windows and Linux (Ubuntu). This computer lab should be ready early November.

Intel compilers new version
C&CZ has bought two licences for concurrent use of the most recent version of the Intel Cluster Studio for Linux. This has been installed in /vol/opt/intelcompilers and is available on a.o. clusternodes en loginservers. The old (2011) version will also be moved to /vol/opt/intelcompilers. To set the environment variables correctly, users must first run:
source /vol/opt/intelcompilers/intel-2014/composerxe/bin/compilervars.sh intel64
After that, icc -V gives the new version number as output.
