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.

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.

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!

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.

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.

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.

Because of tax liabilities and to make it possible to view details of old purchase orders, C&CZ had to keep these systems running until now. Because these systems have been phased out now, the DNS domain name dbf.kun.nl, which still reminds of the Directorate B-Faculties of the Catholic University of Nijmegen, can also be removed.
