Terminal server ts2 and print server drukker
[n]] In het kader van het opheffen van het NWI Active Directory domain zullen deze twee server verhuizen van het NWI.RU.NL naar het B-FAC.RU.NL. Dit zal per ....datum.... geschieden. Deze aanpassing heeft consequenties voor het inloggen op de terminal server ts2 als ook het aankoppelen van printers van de printserver drukker.
Indien men nu op de ts2 inlogt met NWI\\loginnaam zal men dit moeten aanpassen naar B-FAC\\loginnaam.
In het geval van de printserver drukker</>, als het aankoppelen van een printer via \\\\drukker.nwi.ru.nl\\printernaam gebeurd, moet dit aangepast worden tot \\\\drukker.b-fac.ru.nl\\printernaam. [/nl] Due to decommissioning the NWI.RU.NL Active Directory domain these two servers will be removed from the NWI.RU.NLand will be readded to the B-FAC.RU.NL. This will happen on ...date.... This change is of consequence for logging on to the terminal server ts2 as for connecting 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 printers using \\\\drukker.nwi.ru.nl\\printername you have to change this to \\\\drukker.b-fac.ru.nl\\printername.

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. One must assume that passwords that have been used in such a hacked site are now known to Internet criminals. Therefore, one 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, one 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.

Eduroam problems and site survey
There are again complaints about the wireless network Eduroam, with authentication as well as with coverage. In case of problems with RU authentication (, , ...) one can try the alternative To improve coverage in the Huygens building, Ronald Versteeg of JS Network Solutions will be measuring in the entire Huygens building for the next four weeks. For restricted access areas he will consult with C&CZ Network admins and/or the appropriate department.The ISC network department will base improvement plans on the results of that site survey.
C&CZ invites everyone to report problems with the wireless and wired network to

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.

Compute clusters today
With the purchase of a.o. a server with 3072 GB RAM by ICIS with funds from the RRF, the C&CZ-managed cn compute cluster has grown to 1324 cores and 7914 GB RAM. The Astrophysics coma cluster, with 320 cores, 240 TB fileserver storage, GPU's and fast Infiniband interconnect is a separate cluster. For more info, see the cn compute cluster page.

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.

Loginserver lilo2 phased out
The five year old Linux loginserver lilo2 (Ubuntu 10.04) will be phased out shortly. All users are requested to switch to lilo3 (Ubuntu 12.04) or the recently announced lilo4 (Ubuntu 14.04). The names lilo and stitch always point to the two Linux loginservers recommended by C&CZ. .

Limit of number of groups increased drastically
The limit of the number of groups with whom one can share files on network discs, has been increased from 16 to 100. This historical problem in the design of NFS has been solved in modern versions of Linux.

Old financial system FNWI switched off after eight years
With the introduction of BASS in 2006, it was decided to not take over data from the financial system of the Faculty of Science, Airbase. 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.

Automatic mail when printbudget becomes too low
When the printbudget is not sufficient, print jobs are no longer processed. Because people do not always know quickly that this is the cause, C&CZ will send an email when the printbudget has become too low. For a personal budget the mail is sent to the personal email address. For a group budget the mail is sent to the owners of the budget group. Send a mail to postmaster if you want to be warned earlier. Please include the name of the budgetgroup and the value of the printbudget at which you want to receive a mail.

Printer queues can be viewed on Do It Yourself page
Viewing the combined queue of all printers is now possible on the DIY page of C&CZ. Until now, this was only possible using the command lpq on the C&CZ-managed Ubuntu Linux login servers and workstations. Now this is possible from all machines using a web browser.

Test of Ubuntu 14.04 on Linux login server lilo4
As a test of the new version of Ubuntu, 14.04 LTS, we have installed a new login server lilo4.science.ru.nl. In a few months it will replace the five year old login server lilo2. The name lilo, that always points to the newest/fastest login server, will then be moved from the two year old lilo3 to the new lilo4. The new lilo4 is a Dell PowerEdge R420 with 2 Xeon E5 2430L v2 processors with 6 cores. Because we enabled hyper-threading, it appears to have 24 processors. It has 32 GB of memory. For users who want 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. Please report all problems with this new version of Ubuntu Linux.

Posters on canvas (for hand luggage)
It is now possible to print on canvas on the poster printer "Kamerbreed". Canvas prints can be folded to fit in the hand luggage. This can be an advantage over a poster print on photographic paper, to be carried in a large tube. The price for printing on canvas is 36 € per A0.
