Maintenance wireless infrastructure at May 19

At Monday May 19, a major upgrade of the wireless infrastructure and its maintenance tool (called Prime) will take place by the ISC. Therefore the wireless service (i.e. Eduroam) will be interrupted several times from 8:00 pm. Existing wireless connections will be lost and new connections will not be possible for some time. Due to the complexity of this operation this maintenance will possibly be continued at Monday, May 26, again with interruptions from 8:00 pm.

National Instruments LabVIEW on Install network share

To make it easier to install NI LabVIEW for departments that participate in the license, all DVDs of the "Fall 2013" version have been copied to the Install network share. License codes can be obtained from C&CZ helpdesk or postmaster. When the 2014 version arrives, it will also be copied to the Install share.

Problem with halting large filetransfers solved

Next Thursday morning, April 24 the ISC network admins will change a setting in the RU-firewall, as a result of a few reported problems with halting transfers of large data files. The firewall does TCP Sequence Number Randomization for security reasons. Therefore TCP SACK will be disabled in the firewall, which makes modern hosts that use SACK no longer having halted connections through the firewall.

ArcGIS campus license?

The ArcGIS (Geographical Information System) software suite is used increasingly within the Nijmegen School of Management, so much that the current number of available licenses is no longer sufficient. They therefore want to know whether other faculties want to participate in a campus license for ArcGIS. A campus license for three years costs €5500 the first year and €8,500 subsequent years. If interested, please contact C&CZ.

Peage MFP Huygens building not available on April 28/29/30

April 28/29/30, the Peage multifunctional (printer/copier/scanner) and the Peage top-up unit near the restaurant in the Huygens building cannot be used. The ISC will investigate then if Peage can also be made available for employees instead of only for students. On April 28, the MFP will be moved to the test location, on April 30, it will be moved back.

Change passwords after Heartbleed OpenSSL bug

If you don't want to read the details below: it is advised to change the Science password on the DIY website. The same holds for the RU password and other passwords for Internet services.

April 7, 2014, a two-year-old vulnerability was announced in several versions of OpenSSL. OpenSSL is used for encrypting network traffic. Because of this vulnerability, an attacker could have retrieved the secret key of a service, with which traffic could be decrypted. In addition to this, due to this vulnerability an attacker could read the memory of the service, thereby retrieving sensitive information like passwords.

After the announcement of this Heart Bleed OpenSSL leak all vulnerable C&CZ services were automatically repaired. On Thursday, April 10th, we have deployed new certificates for these services. The old certificates will be revoked. If one has used one of these C&CZ services, it is wise to change the Science password on the DIY website. The old password could have become known to an attacker. For the full list of C&CZ services that were vulnerable and references to vulnerable external services, see the C&CZ certificate page. The most used ones are:

  • Mail users:
    • squirrel.science.ru.nl: The old Science webmail service was vulnerable since January 29, 2014.
    • roundcube.science.ru.nl: The new Science webmail service.
    • autoconfig.science.ru.nl: The website for automatic configuration of mail clients like Thunderbird and Outlook.
  • Lecturers: dossiers.science.ru.nl and eduview.science.ru.nl
  • MySQL database owners: phpmyadmin.science.ru.nl
  • FNWI news letter editors: newsroom.science.ru.nl

Eduroam adjustments March 27

The ISC let us know that Thursday evening March 27, they will change settings of the controllers of the Eduroam wireless network, in order to resolve problems. Please report to if you notice improvements due to these changes or if they seem to cause problems.

This is separate of the earlier announced adding and moving of wireless access points in order to improve the wireless coverage in the Huygens building before the end of April.

C&CZ invites everyone to report problems with the wireless and wired network to

XP support ends on April 8!

As announced before, from April 8 Microsoft will no longer support Windows XP. Therefore C&CZ urges everyone to change to a different operating system before that date, if possible. XP computers that cannot be upgraded, e.g. because they are attached to a measuring device which requires XP, can be moved to a shielded part of the network. PC's can be upgraded to a C&CZ managed Windows 7 and/or Ubuntu 12.04 PC. On a Windows7 managed PC, a department can have local administrator (localadmin) rights. One can also ask C&CZ to just install Windows 7 and/or Ubuntu 12.04 on a PC, after which the user can manage the PC her/himself. Please contact the C&CZ helpdesk if you want to make use of this possibility. Please note that if a PC doesn't have the required hardware, one will have to buy new hardware, e.g. a memory upgrade or a new PC entirely.

Password lock-out only after 10 false attempts

Until today, a Science account was locked out after 3 consecutive false login attempts. This has changed: now only after 10 false attempts the account is locked out for 30 minutes. This way the behaviour for the Science account and for the RU account are identical.

Note that you are not forced to change the Science or RU password on a regular basis. Yet we advise everyone to do so as changing passwords once in a while adds to the security. But please think of all devices where this password is stored (laptop, smartphone, home PC, etc.).

Matlab R2014a available

The latest version of Matlab, R2014a, 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-R2013b/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.

Producing booklets with the Konica Minolta MFP pr-hg-00-002

In the Konica Minolta MFP pr-hg-00-002 a punch unit and a saddle-unit that can fold have been placed. This makes it possible to produce complete booklets. One can punch 2 or 4 holes. At maximum 20 sheets can be saddle-stitched and folded, so one can produce an A4 booklet from A3 sheets or an A5 booklet from A4 sheets.

Eduroam and wired network adjustments

After complaints about the Eduroam coverage in the Huygens building, a plan has been made to move three wireless access points and nine will be added. We expect this to be realized before the end of April.

The planned changes in the wired network outside working hours in preparation of IP telephony, have been postponed, because it appeared that the network had become less stable.

C&CZ invites everyone to report problems with the wireless and wired network to

SURFnet FileSender: send large files securely

Since February 24, securely transfering large files has become possible for employees with a @science.ru.nl mail address with the experimental version of SURFnet FileSender. Files up to 100GB can be sent to a maximum of 25 recipients. You can also send others a "guest voucher" with which they can make use of this service. The transfer of files is encrypted (https) to a server of SURFnet in the Netherlands. FileSender is often more useful than alternatives because of the maximum size or the information security. The SURFnet FileSender service is based on the FileSender project, in which SURFnet participates.

F-Secure security software: for Mac and Android too

On self-managed computers that have been purchased with RU funds or through external funding for the benefit of Radboud University, you are allowed to install the RU paid version of F-Secure. There is a version for MS Windows 7 and 8 and there is a Mac version.

The price of F-Secure for privately owned computers (Windows PCs, Macs en Android) has been lowered for employees as well as for students to € 2 per year. At Surfspot search for Secure. Of course, you can install different security software instead, like the free Panda for Windows 8, the free Avast voor Windows 7 or possibly the free Microsoft Security Essentials for Windows, that is only seldom recommended.

Scanning on the Konica Minolta MFPs

Update: as of February 27, the settings of all Konica Minolta MFP network switch ports have been changed. Please report remaining problems to C&CZ.

Scanning to e-mail sometimes doesn't (didn't?) work on the KM MFPs. It can temporarily be resolved by switching the machine off and on again. An alternative is scanning to a USB stick. Log in at the MFP with the scan pin, put a document in the feeder or on the document glass, select Scan and then plug the USB stick into the USB port on the right side of the MFP, on the top side. After a few seconds the MFP recognizes the USB stick and presents the choice "Save a document to external memory". Choose OK and press Start. See also the RU manual on the RU-page about the MFP's.

Julia programming language

The Julia programming language is available as of today on the Linux login servers. Julia is a high-level dynamic programming language designed to address the requirements of high-performance numerical and scientific computing. The most notable aspect of Julia is its performance, which often comes within a factor of two of fully optimized C code. If you want Julia to be available on other computers too, please contact C&CZ.

BASS problem with Java 7 resolved

The ISC let us know that after the installation of patches installed in BASS during the weekend of December 1, the possibility to use a recent version of Java (version 7) had erroneously disappeared. As of February 11, 2014 this issue has been resolved. The function in BASS to work with all versions of Java SE (JRE) on the client (PC) has been reactivated. Furthermore all JAR-files in BASS have received a security certificate (they have been signed), with which it possible for BASS to work with the latest Java SE versions (Java SE 7.51 en hoger). BASS users who work with Forms, will see pop-up windows asking "Do you want to run this application?". Of this a description has been made on the RU Intranet.

Tele lecturing and video conferencing

There is a tele lecture room at the Faculty of Science: HG00.108. This facility makes it possible for students who are elsewhere in the world, to participate virtually and interactively in a lecture given in this room. The other way around is also possible. Moreover in the large conference room HG01.060 a video conferencing facility has been created. This setup also serves as backup for the tele lecture facility. For help and advice please contact the Audiovisual Department of our faculty.

RU uniform print costs

As of February 1, C&CZ will change the [http://wiki.science.ru.nl/cncz/Printers_en_printen?setlang=en#.5BKosten.5D.5BCosts.5D print costs], in agreement with the RU Executive Board decision to make print costs uniform within Radboud University. The price for black&white A4 will increase 5.7%. Costs for A4 color, A3 black&white and A3 color will be lowered by 18%, 54% and 31% respectively. Because we hope that the C&CZ print system will be replaced by the RU wide Peage system in the near future, we will not immediately prioritize to adapt the C&CZ print system to make single-sided more expensive than double-sided, as is now the case elsewhere on campus.

Peter van Campen 27 jan 2014 16:48 (CET)

New network disks bigger and less expensive

Because C&CZ has a new file server, we can lower the pricing of network disks by 50%. Due to the recently announced new backup service larger disks (400GB) are also possible. A new option is an un-backupped disk, which is four times less expensive. Such a disk could be used for copies of a local disk. Contracts for hiring a network disk are still entered into for a period of three years. Existing contracts are not changed.

MobaXterm: powerful X11/SSH/etc. client for Windows

MobaXterm is now available on the S-disk. It is a powerful and easily usable alternative for X11/SSH software like Xming, Xwin32, WinSCP and Putty. From the MobaXterm website: "MobaXterm is an enhanced terminal for Windows with an X11 server, a tabbed SSH client and several other network tools for remote computing (VNC, RDP, telnet, rlogin). MobaXterm brings all the essential Unix commands to Windows desktop, in a single portable exe file which works out of the box." The support of OpenGL could also be a reason to start using MobaXterm. If you use it professionally, you should consider subscribing to MobaXterm Professional Edition. We already reported that the support of X-win32 ends January 31, 2014. If you still need to switch, MobaXterm is a good choice.

Automatic configuration of mail clients

When installing a mail client it is now possible to configure all settings (login name, IMAP and SMTP server and parameters) automatically for most of the C&CZ mail domains. In general you just need to fill in your main mail address. For details, see the mail service page. Using a webmail service like Roundcube is even simpler, there are no settings to fill in.

Laptops without wifi to use for examinations without Internet access

It is now possible to borrow laptops from the Science laptop pool with wireless network switched off. These laptops can be used for examinations to allow students to use a computer without giving easy access to the internet. Wifi has been switched off by default on two laptops in the pool by request of the Education Center in order to assist disabled students with examinations. For larger examinations, please reserve the laptops in time, specifying the need for wireless networking switched off if necessary.

Backup service completely renewed

C&CZ makes backups of all important network disks. In the last months the backup service has been completely renewed. It's now faster and has a larger capacity to cope with the growing disk space demands. If you lose files on one of the network disks, please contact C&CZ a.s.a.p. and provide the name of the network disk and files, and the time period in which the files were still present.

Postponed replacement of home-server "bundle"

  Begin        : 20131223 07:30
  End          : 20131223 09:00 (expected)
  Affected     : Users with homedirectory server "bundle" (as can be seen on http://DIY.science.ru.nl)

The replacement of the old home server "bundle" has been postponed and will now guaranteed take place on Monday morning December 23. Because the data have been synchronized with the new server, there will not be much downtime. The new server should be very dependable: hardware RAID-6, double processors and power supplies and a 5-year support contract from the supplier. The performance has improved, e.g. by using hardware RAID with a 1 GB write cache with battery backup.

Upgrade F-Secure security software

The most recent version of F-Secure can be bought by RU employees now for ca. € 5,25 at Surfspot, search for "secure". It is F-Secure Internet Security 2014 for 1 year, for 1 user. This version also supports Windows 8. F-Secure for Android and Mac are available with the same license. The support for version 9, that could be used freely at home, ends on February 6, 2014. The business suite version that is used on campus, that can be found on the Install network share, can't be used at home, since it needs to communicate with a policy manager. N.B.: The private license doesn't cover use by family members or roommates. See Radboudnet news for more info and updates.

Ru-wlan wireless will be discontinued, switch to Eduroam in time

In all buildings of Radboud University the Eduroam wireless network is now available. The wireless network ru-wlan will be discontinued on January 15, 2014. Please switch to Eduroam as soon as possible. One can login with U- or S-number@ru.nl and RU-password or with science-username@science.ru.nl and Science password. Note: Laptops with Windows 8 sometimes do not connect automatically to Eduroam. If this is the case, choose "Microsoft: Protected EAP (PEAP)" at the prompt "Choose network authentication" during configuration. The iPhone, iPad and iPod cannot cope with multiple corporate networks, so one has to 'Forget' ru-wlan before configuring Eduroam. Wireless network configuration manuals for various devices and operating systems are available on the IT Servicecenter website.

Don't fall for phishing mails!

When you get a mail pretending to come from "C&CZ" or "RU Administrator" asking you to mail or provide your username and password to some website in order to prevent problems: do not fall for this. Because if you do react, you will cause problems! Internet criminals will use the credentials to spread spam through our mailservers. They will also have access to all of your mail on the IMAP server and all of your files. The past few weeks no less than five FNWI employees and students fell for such a phishing mail, with serious consequences for all users.

KM printers/copiers/scanners active, Ricohs removed

All Konica Minolta MFP's are in production now, all Ricohs have been switched off. KM has changed the settings of a few printers to print only b/w, preventing accidental color pages. We advise everyone to try to set the printer configuration on your desktop to print default in b/w. Printing and scanning works roughly the same as with the Ricohs. Employees of the Faculty of Science can contact C&CZ to get a PIN code for copying. Students can make copies by using the Peage MFP near the restaurant, or make copies by scanning and printing afterwards.

PC's computer labs: more and new

The page about the computer labs lists all details about the PC's in the computer labs. The most important changes are:

  • The old PC's in TK029, TK206, Study area, Library of Science, Project rooms and Flex workplaces have been replaced by new HP Compaq Elite 8300 PC's, which are All-in-one PC's.
  • In the study area extra PC's have been installed.
  • A new lab TK702 has been created with 17 PC's.

Xafax copier units removed

As announced before, the Xafax copy units will be removed, starting July 23, 2013. Shortly therafter, the Ricoh MFP's will be removed. The new Konica Minolta MFP's have been available the last few weeks. FNWI-emplyees can get PIN codes for copying from C&CZ. Therefore we expect no problems from the removal of the Xafax units. Students can make copies by using the Peage MFP near the restaurant, or make copies by scanning and printing afterwards.

End of Science wireless, enter Eduroam

In the near future the preparations will start for the Eduroam wireless network in the Faculty of Science buildings and the increase of capacity of the wireless network. This also marks the end of the Science wireless network, as was announced earlier.

The work will probably start on August 5. Over the course of a few weeks the Science network will gradually disappear while the Eduroam network appears. Because of this transition period we strongly advise to switch all wireless devices to ru-wlan before that time.

  Affected     : Users of horde webmail and users wanting to send mail to e.g. hotmail.com

Horde webmail again appeared to be misused for sending spam. This could happen because a naive user gave the Science password to phishers/spammers. After first stopping horde, this night we disabled the account of the naive user and restarted horde. This morning it appeared that this short spam-outbreak had caused administrators of hotmail.com to add our mail server to their blacklist. Therefore we switched the IP-number of this mail server and asked Microsoft to remove the old IP address from their blacklist.

Linux login server lilo3 replaces lilo1

A new Ubuntu 12.04 Linux login server lilo3.science.ru.nl is available. Therefore the six year old login server lilo1 will be phased out soon. The name lilo, that always points to the newest/fastest login server, will also be moved from the four year old lilo2 to the new lilo3. The new lilo3 is a Dell PowerEdge R410 with 2 Xeon L5640 processors and 32 GB memory. 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: 3e:b9:89:4d:53:9b:8f:4a:97:b2:a1:c3:0d:74:34:2c.

Ricoh and Xafax replaced by Konica Minolta

In a few weeks we will place new Konica Minolta (KM) multifunctionals (MFP's) next to the Ricoh's and some other places. After a short period, in which one can switch from Ricoh to KM, we will remove most of the Ricoh's. Until July we will have a Ricoh with Xafax-pole in a few places, so one can empty the Xafax-cards. Because the RU-wide Peage-project is still not in operation for employees, the new KM's can be used like the Ricoh's. The only difference is that the Xafax-poles will be removed because the contract with Xafax ends and cannot be continued. Copying on th KM's therefore will be only be possible after entering a code. We will contact departments about the code and about the budget/kostenplaats from which the copy costs can be reimbursed. If you do not have a code, copying can be accomplished by scanning and printing.

CMS functional manager Wim Janssen stationed at C&CZ

On April 15 Wim G.H.M. Janssen (IMAPP and facultary CMS functional manager) will "move in" with C&CZ. Wim will remain employed by IMAPP but will be able to perform his work more effectively from his new location at C&CZ because of our frequent collaboration. Moreover C&CZ will take over some of his tasks thus creating the possibility for new developments. There may be some confusion: for many years C&CZ also has an employee Wim P.J. Janssen, so more often a Wim-Wim-situation will arise.

Electronic cost declaration through i-Expense, also from home/Internet

Since the introduction of i-Expense, the electronic cost declaration module in BASS-Finlog - the financial computer system of our university, the number of BASS users has increased enormously. New users need to be aware whether they can access BASS directly or only through the so called Port Forwarder. Recently, access from home/Internet has been made possible if one uses VPN. More information on this can be found on the BASS page and in a previous [news article] about using BASS in combination with the RU firewall.

Logging on to BASS may be cumbersome or impossible from certain workstations because the BASS infrastructure does not support all kinds of PC-systems seamlessly. Cost declarations on paper are allowed if logging on to BASS fails for some reason, until the logon difficulties are solved. The central organisation and C&CZ work together to this end.

The web application can be found at https://bookings.science.ru.nl. Because the application was written as a generic solution, it will soon also be used for the lending system of laptops by the Library of Science. If you have a booking/reservation question which may be solved using this application, please contact C&CZ.

New Functional Manager CMS

For many years everyone at FNWI who was involved in websites based on the RU Content Management System (CMS) relied on Peter Klok for help and advice. In IT terms Peter was our functional manager. Because of Peter's retirement this role was taken over by C&CZ. This means that all support questions regarding the websites of the Faculty of Science, regardless of the underlying technique, can be directed to C&CZ. In practice the support task for the CMS is in the hands of Wim G.H.M. Janssen, IT specialist at the IMAPP institute. C&CZ (especially Fred Melssen) will function as Wim's backup.

Replacement of Ricoh multifunctionals by Konica Minolta

The European tender for multifunctionals (printer/copier/scanner) for the university was won by Konica Minolta. This means that the current Ricoh machines will be replaced. There is a project to make the print/copy/scan system Péage suitable for employees. The printing and copying costs for employees will be charged to their "aanstellingskostenplaats", i.e. the current budget groups will disappear. Until this project is completed successfully, the C&CZ printbudget system will be used.

  • Since the new Peage system will not support Xafax copycards, it is advised to minimize your local stock of Xafax copycards.
  • The first Konica Minolta MFP's will be placed for the expansion to Huygens 2.0 (Mercator 1).
  • The first replacement of Ricoh-machines in FNWI will be in April: the Peage printer Watt near the restaurant.

More IP-numbers for ru-wlan and Science (wireless)

Monday, March 4th 2013 at 18:00 hours, the number of IP numbers that is available in the FNWI buildings for ru-wlan and Science was doubled, as was announced shortly before. Because ru-wlan moved to a new range, users of ru-wlan lost connectivity for at most 15 minutes. There was already a plan to replace ru-wlan and Science within the FNWI buildings by the RU-wide Eduroam and ru-wlan, but the wireless network usage had grown so fast that we could not wait for this plan to be realized. The week before, some wireless users at times could not even get an IP address, although the lease time had been brought down to 30 minutes. Therefore this temporary measure became necessary on such short notice. Because there are more IP numbers available now, more users can nowswitch from Science to ru-wlan wireless, in preparation for the realization of the plan mentioned above.

Phishing mail: "Belangrijke boodschap met betrekking tot uw Radboud Universiteit Webmail" en "Fwd: Your e-mail will expire soon"

Recently a number of employees of the Faculty of Science received a phishing email with the subject "Belangrijke boodschap met betrekking tot uw Radboud Universiteit Webmail" and content "Nieuw Belangrijk Veiligheid Bericht Alert! Inloggen om het probleem op te lossen." Others received mail with subject "Fwd: Your e-mail will expire soon". The link provided in the mail points to a copy of our Horde webmail service. Big differences are:

  • the URL is not within science.ru.nl
  • it is not a secure https connection, the lock is not present
  • the account name and password that you type in, do not arrive at C&CZ servers, but at Internet criminals. They can then access all files and mail of that Science account. Usually the criminals try to use the user credentials to send spam via our mail servers. This is something we notice; in such a case C&CZ will disable the user account a.s.a.p. to prevent further abuse of the account and to prevent our mail servers from ending up on black lists.

It is not the first time we see a phishing attack specifically aimed at Science-users and it will most probably not be the last time either. Please stay alert! If you want to read more about phishing, please see this monthly security newsletter.

Recommendations after nu.nl hack

The popular Dutch news website NU.nl has been compromised and altered to serve a malicious worm to those who visited it on March 14, 2012 between 11:30 and 12:30. PC's with older versions of Adobe Reader and Java may have been infected with the Sinowal worm, that is designed to steal passwords, online banking information and other sensitive data. We heard reports that up-to-date installations of F-Secure Client Security blocked this malware. According to ComputerIdee only a few security software suites recognized this malware. The version of Hitmanpro mentioned there has been copied to the Install network share, for employees and students who want to scan their PC.

General recommendations to limit risks:

  • Always update all software, especially browsers, mail clients and software used to show content from the Internet: Java, PDF-readers (Adobe, ...), Office suites, Flash, ...

New Matlab license server (old one goes away!) and Matlab R2012a

There is a new license server for the use of Matlab. Users entitled to a license can request the new license codes by sending a mail to postmaster. The old license server will be brought down in the not too distant future, so to avoid problems, all installations of Matlab have to be updated, also older versions! The latest version of Matlab, R2012a, is available for departments that have bought licenses. The software and license codes can be acquired 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 have this version installed, an older version (/opt/matlab-R2011b/bin/matlab) is still available temporarily. The C&CZ-managed Windows machines will receive this version too.

Please use ru-wlan instead of Science wireless!

In the near future the wireless access points in the Huygens building and the buildings around it, will be replaced by new ones, based on a new technique. The Science wireless network will then no longer be available. Therefore please switch over to using the ru-wlan wireless network, that is available before and after. One can use ru-wlan with U-number and RU-password, but also with and Science-password. After the switch, faster (wireless-N) access points wille be used in busy areas. After the switch the eduroam wireless network will be available too, one can use that with and RU-password, but also with and Science-password. Before the switch, eduroam is only available near the Huygens building on the terrace behind the restaurant. In the future ru-wlan will be switched off, only eduroam will survive. Furthermore, there is a plan to have more wireless access outside of the Huygens building, i.e. at the central entrance and the grass behind the Huygens building.

Which computer lab has free PCs?

Since recently, the website welke.tk shows which computer lab has free pc's. Advantages of this site over the existing current usage page are that it is realtime and that one can immediately see whether a lab is or will be reserved for lectures. The website welke.tk can be viewed on smartphones too. The website has been created by Bas Westerbaan in cooperation with C&CZ, the design was made by Judith van Stegeren, Ruben Nijveld helped with mobile support.

Network problems after change of January 28 solved

January 28, the UCI network management installed new software and a new configuration on the Science Faculty router, among other things to prepare for IP telephony. The following week some network problems were reported, which have been traced to a high cpu load of the router. After a few temporary measures were taken, on Monday January 28 18:00-18:45 a new configuration was installed, after which the cpu load hasn't been high again and the network problems appear to have been solved more permanently.

Split-view DNS could influence Internet at home

Anyone using at home a science.ru.nl nameserver like ns1.science.ru.nl, should remove these DNS-servers from the list of DNS-servers, because we started using split-view DNS. With split-view DNS, we can give internal (RU on campus) pc's answers differing from those given to external pc's. The UCI introduced this a few months ago for e.g. the DNS zones ru.nl and heyendaal.net to increase IT security.

Never react to an e-mail that asks for your password!

A few days ago one of our users replied to an e-mail that apparently was sent by "support" and asked for username and password. This account was later misused to send hundred thousands spam-mails through our mail server. This resulted in the blacklisting of our outgoing mail server in e.g. the blacklists of Windows Live Hotmail. The fastest way to remedy this is to give our outgoing mail server a different IP-address, which we did this morning. Lesson: Never reply to an e-mail that asks for your username and password! It causes a lot of trouble for us and other users.

Milestone Linux Compute Cluster: 512 CPU-cores and 1024 GPU/CUDA-cores

Early 2006 a faculty Linux compute cluster was started by the purchase of 4-core rackmountable servers by several departments. The latest additions to the cluster, a machine with 48 CPU-cores and a machine with 12 CPU-cores and 1024 CUDA GPU-cores in 2 NVIDIA Tesla M2090 cards, brought the size of the cluster to these milestone figures. Source code has to be rewritten to make use of CUDA-cores. The latest version of Matlab has support for the use of CUDA-cores. For workstations and servers, including these compute servers, Fedora Linux is gradually being replaced by Ubuntu LTS Linux.

BASS and single logon

For security reasons direct access to the concern application BASS used to be blocked, even from within the RU internal network; one had to logon to the Port Forwarder first which meant two logons in a row. With the RU central firewall in place the first logon is not necessary anymore (although still possible) for PC's which are located behind the firewall from a network topology point of view. A significant amount of the PC's in FNWI have already been relocated behind the firewall. On the BASS page under System Configuration you can see the current status of your PC and how to configure your PC to be able to switch to single logon.

The coverage of the Vodafone mobile network in the Huygens building has been improved considerably, it should be good in the whole building now. We plan to connect the mobile networks of KPN and T-Mobile to the newly installed Distributed Antenna System as well. The improved coverage is a necessary step to use Vodafone Wireless Office, which allows phone calls to and from cell phones using the RU-internal five-digit numbers. The future of enterprise telephony for Radboud University consists of Voice over IP for desktop phones and Wireless Office for cell phones.

USB-sticks causing infections

Many PC infections occur because the malware on a USB-stick is automatically started when you connect it to the PC, resulting in an infected PC. You can prevent this from happening by disabling the ‘autorun’-option on the PC.

Leaving your office for a few minutes? Then make sure to have your screen locked! If you leave your computer unattended (using no screensaver with password protection) and your room hasn't been locked, there is a chance that the data on your PC could be compromised, or that illegal actions could be carried out by someone. During the campaign, we will devote extra attention to unattended PC’s. You might be surprised to find a 'static' sticker on your monitor. You can turn on screen lock on a Windows computer by pressing the Windows and the L-button simultaneously.

Spamming PC's noticed faster

CERT-RU, that coordinates RU IT-security incidents, regularly receives reports about PC's that are distributing spam mail. Often these have been noticed by Senderbase, because the daily mail volume has been much larger than the monthly average. The routers at the Science Faculty log the initialization of an SMTP-connection outside Radboud University. Therefore spamming PC's often already have been cleaned when CERT-RU gets noticed by an outside party.

Changes in IT services

On September 1, 2009 GDI (Gebruikersdienst ICT) was formed by combining the former Computer Support Groups (COG's) of the various faculties and clusters of our university. Because of the special role of IT for FNWI, C&CZ continued to exist as the IT service group for FNWI.

Based on a formal decision of the Executive Board all standard Windows workstations and student PC's campus wide will be transferred to GDI. C&CZ will remain responsible for all other IT services in this faculty. At the moment GDI is preparing the transfer of the Windows workstations of the service departments as well as all course PC's. Users will be informed in time about the consequences of these changes. Until the takeover, which will take place in steps, C&CZ will remain responsible for all IT services for FNWI and will remain reachable through the well known channels.

Ubuntu login server

In the process of gradually replacing Fedora by Ubuntu, there have been several Ubuntu clients and servers installed. One of these is an experimental Ubuntu 10.04 LTS (Lucid Lynx) login server lilo1.science.ru.nl for general use.

The choice for Ubuntu 10.04 LTS (Lucid Lynx) has been made because of the L(ong) T(ime) S(upport), 3 years for desktops and 5 years for servers. This in contrast to approximately 1 year updates and support for Fedora. Software, commonly used within the faculty, is available.

More likely than not, packages or programs will be missing or work in slightly different ways than on a Fedora system. It's also possible that settings for Fedora might cause problems on the Ubuntu systems. Please do not hesitate to report problems. Regrettably, we cannot garantee that all problems can or will be solved immediately.

Wim Janssen 16 feb 2011 09:53 (UTC)

New names for Linux login servers

Currently the login servers are named lilo.science.ru.nl (LInux LOgin server) and stitch.science.ru.nl. However, the actual machines have different names, porthos.science.ru.nl and lijfwacht.science.ru.nl respectively. This leads to confusion with some of our users. To address this issue we will phase out and rename some machines.

The oldest server lilo.science.ru.nl will be phased out no sooner than lilo1.science.ru.nl can take over. The current Fedora login server stitch.science.ru.nl will be renamed to lilo2.science.ru.nl.

The name lilo will eventually become an alias for the fastest login server and the name stitch will, for the time being, become an alias for lilo2. Whenever replacing login servers, new machine will receive a successive number, so lilo3, lilo4, etc.

Microsoft Office 2007

Currently the default office software on campus is Microsoft Office 2007. We tried to install this software on as many PC's as possible. If you still use an older version of Office then we would advise to install Microsoft Office 2007.

If your PC is owned by the university than you are allowed to use the campus license and you can borrow the software from our department or do the installation directly from the install disk (\\install-srv.science.ru.nl\install).

For privately owned PCs you can buy the software at a reduced price at Surfspot.

Windows print server

A new Windows 2008 printer server has been installed to support departemental printing. The server is named drukker.nwi.ru.nl -- edit 2014-11-18 renamed to drukker.b-fac.ru.nl. This server can support printing from Windows XP, Windows Vista (32 and 64 bit) and Windows 7 (32 and 64 bit). Printer drivers are automatically installed by connecting to the printer server and selecting the print queue.

Pros:

  • Currently very little problems occurred

Cons:

  • Only for standard, frequent installed, common available printers (HP LaserJet, Xerox, Ricoh)
  • Little protection against abuse
  • Cannot make use of the CnCZ print budget software, so no accounting or print budget facilities

This implies that only printers that are not publically available should be considered adding to this server. Please contact CnCZ to figure out if a printer is suitable for installation.

See Printers_en_printen for an explanation how to connect printers.

New mail/calendar service Share

The UCI has developed a new combined mail and calendar service for the RU. The service called Share is based on the open standards product Zimbra. All RU students and a selection of RU employees are already using Share. Deployment of Share at FNWI depends on the migration of the FNWI Exchange accounts to Share. This migration in turn requires a number of shortcomings in Share to be resolved. At the moment it is unclear when Share will be available for FNWI.

Matlab R2010b

The latest version of Matlab, R2010b, is available for departments that have bought licenses. The software and license codes can be acquired through a mail to postmaster.(/opt/matlab-R2009b/bin/matlab) The software can also be found on the install-disc. The C&CZ-managed 64-bit Linux machines have this version installed, an old version (/opt/matlab-R2009b/bin/matlab) is still available temporarily. The C&CZ-managed Windows machines will receive this version within a few days.

print_mail_to_link('_Science-mail_forwarded_to_', 'student.ru.nl')">New students: Science-mail forwarded to @student.ru.nl

In the first weeks of the new college year, mail sent to new students @student.science.ru.nl, has been forwarded to their Studielink address, because no @student.ru.nl address was available. Today, this forward has been changed to the @student.ru.nl address, because Biology otherwise could not send mail to all new students. If a new student wants to change the forwarding address, that can be done on the Do-It-Yourself website.

Save settings on B-FAC PC's

If you want to save your user settings when logging in on the PC's in study landscape, computer labs, etc., you have to login to the Do-It-Yourself website and check in Profile: "Roaming profile for B-FAC domain". This makes logging in a bit slower, because all user settings have to be copied from a server. The advantage is that all user settings are saved when logging out. An example of such a user setting is the trust of all "ru.nl" sites in the NoScript extension for Firefox, that is necessary to use e.g. Blackboard. New logins from now on will get a roaming profile in all domains.

Ben Polman 22 sep 2010 17:44 (UTC)

New head of department

November 1, 2010, Peter van Campen will go back to an administrator/developer function, the new head of C&CZ will be Caspar Terheggen.

Peter van Campen 22 sep 2010 13:44 (UTC)

Copy cards go away

The copy cards with a magnet strip, that can be used with the multifunctional copiers, will go away, starting in a few months. To print and copy in the future Peage-systeem, one needs a chip card and a network budget. In the near future the first multifunctional in this new system will be placed in the central hall of the Huygens building. The first few months this system can only be used by students, so the other Science-multifunctionals will be switched to this new system later. Departments are advised to keep less copy cards in stock.

Peter van Campen 22 sep 2010 09:06 (UTC)

Remove printjobs from Linux

The removal of submitted print jobs is now possible from Linux. It can be done with the lprm command. It works from all C&CZ managed Linux servers and workstations, 32-bit as well as 64-bit.

Miro printer alternatives

The old printer miro has been out of order for a few weeks, but has been repaired now. There is no longer a service contract for miro, we try to keep it up and running, if only to finish the remaining toner cartridges. If you really preferred the output of this Xerox Phaser 7300DX over the other (Ricoh, HP) color printers and also over the printers of the RU copyshop, please report to C&CZ. C&CZ then can decide about the purchase of a new printer.

Symposium Education-IT on occasion of Kees Keijzers leaving

On occasion of Kees Keijzers leaving the Science Faculty, the Education Center (OWC) and the Computer- en Communication Department (C&CZ) organize a symposium in the Linnaeus building Friday, October 1 from 13:15 hours: "Simulation and copying in the lecture-room: education innovation with IT". The symposium shows products for education, that are a results of close cooperation between lecturers and IT workers at short distance, with feeling for the field of study.

For the programme and detailed information, see the invitation (in Dutch).

When asked for password through mail: do not react!

Every so often our users receive phishing-mail, in which a prompt response with username and password is requested. C&CZ likes to stress *again* that it is not very wise to believe something just because is written in a letter or e-mail and that *no official institution* will ever ask you for your password, just like a bank never will ask you for your pincode for your bank account. If a naive user falls for this scheme, his account is normally soon thereafter misused to send spam, with the effect that our mailservers are included in blacklists, causing problems for all users.

Microsoft Office 2007 installed in educational PC rooms

Microsoft Office 2007 has been installed on all PC's in the educational PC rooms, replacing the previous version, Office 2003. Help is available for the switch to Office2007:

Wim Janssen 9 aug 2010 07:52 (UTC)

Education PC's usable by all RU-students

All RU students can now use the PC's in the educational PC rooms of the Faculty of Science. Choose the RU-domain and then login with your RU-account (S-number and RU-password).

RU employees will be able to login with their RU-account when the "provisioning" of the RU-accounts (U-number and RU-password) to the RU Active Directory domain has been realized.

Employees and students of the Faculty of Science can of course login to the B-FAC domain with their Science account. Other employees or guests can request a temporary Science account through their departmental contact.

Wim Janssen 5 aug 2010 13:42 (UTC)

Personnel changes: Jos Alsters, Pauline Berens

November 1, 2010, Peter van Campen will go back to an administrator/developer function, the new head of C&CZ will be Caspar Terheggen.

Jos Alsters has left C&CZ as of July 15, 2010. He has started his own ICT company Itsal.nl, " IT Services from Open Standards". C&CZ intends to hire Jos for some assignments.

On the same day Pauline Berens started at OWC (Education Centre) and C&CZ as IT-administrator/developer for Science education.

End of life of Solaris servers: Solo and Solost

The Solaris login servers solo and solost will be phased out on July 1, 2010. Please switch over to the repacement Linux servers lilo and stitch. In case of problems Postmaster can help. The phasing out of all Solaris servers marks the end of the system administration for this operating system. Because there are plans to switch to a different Linux distribution for servers and/or workstations, the number of supported operating systems will be constant in the near future.

Wim Janssen 21 mei 2010 07:52 (UTC)

Microsoft Office 2007

C&CZ will deploy Microsoft Office 2007 Enterprise to all Managed PC's. Up till now Office2007 was only installed on request of departments, because of the completely different look and feel and compatibility issues. Office2007 will be installed on the Study Landscape PC's shortly, the PC rooms used for courses will follow during the summer holidays.

Departments can contact C&CZ to start an automatic deployment of the software to their managed PC's. For self-administered PC's, one can use the install network disk to install Office 2007. Necessary license codes are mailed by Postmaster on request from a faculty or RU mail-address.

Help is available for the move to Office2007:

  • A Learning Guide for all parts of Office2007 (Word, Excel, PowerPoint, Outlook, Access) and also for Windows7. This can only be used on campus and is only available in Dutch.
  • The (Dutch) information site of the Office 2007 project of the GebruikersDienst ICT
  • Walk-in sessions with a teacher explaining Office2007 and the Learning Guide: Thursday May 27 in E.1 2.50 (Erasmus building, low-rise, room 2.50). Hours: 10:00-11:00, 11:00-12:00, 14:00-15:00, 15:00-16:00. Tuesday June 8 in Gymnasion GN3. Hours: 10:00-11:00, 11:00-12:00.

Students test new copy/print system

The test by students mentioned below has been ended, the Peage project continues. For the Peage project, that aims to deliver a new print/copy-system for Radboud University, C&CZ was looking for 25 students. These students received € 50,- print/copy budget in the new system. The requirements to participate were:

  • student of the Science Faculty
  • having an OV-chipcard
  • present at the instructional meeting, Thursday May 27, 12:30-13:30 hours in CC3
  • willing to print/copy during the test period (until July 2, 2010) on black/white printers/copiers in the Faculty of Arts, Medical Faculty, Nijmegen School of Management and the Science Faculty
  • willing to share experiences in the evaluation

The first 25 reacting by mail to Peter van Campen have been selected, closing date was May 25.

Peter van Campen 19 mei 2010 15:22 (UTC)

Reduce mail from *-studenten-* mailing lists

Student representatives reported to C&CZ that some students would like to reduce the amount of mails they receive from the Mailman mailing lists. The mailing lists for students are the umbrella list fnwi-studenten, and the lists per discipline and year that make up the umbrella list. Therefore C&CZ changed the configuration of the -studenten- mailing lists, so digests (summaries) for the -students- mailing lists are only mailed once a week. Of course this only has an effect for students who have selected to prefer to be mailed a digest instead of receiving every mail separately. For all other Mailman mailinglists a digest is mailed once a day. The digest option can be selected per user per mailing list, e.g. on the -studenten-discipline/year mailing list website, through "change your subscription options".

Peter van Campen 21 mei 2010 10:37 (UTC)

Study landscape attendant for problems in PC-rooms

C&CZ and the Library of Science start a test on May 3, with using the study landscape attendants for problems in PC-rooms on the ground floor of the Huygens building. During this test, problems with PC's in these rooms should preferably be reported to the study landscape attendant. The attendant will also regularly check for violations of the rules of behaviour (no eating, drinking or causing inconvenience).

New Windows Terminal Server for BASS-Finlog and Tracelab

Because the current Windows terminal Server ts1.nwi.ru.nl shows some hardware problems, we decided to replace the machine. The new machine is a virtual Windows 2008 Terminal Server. This implies the Windows user interface has changed, it looks more like Windows Vista or Windows 7. Connecting to this machine should work the same as with the previous server, just change the name ts1.nwi.ru.nl to ts2.nwi.ru.nl. This machine is primarily intended for using BASS-Finlog and Tracelab.

Wim Janssen 23 apr 2010 13:25 (UTC)

Roaming user profiles for Windows can be enabled and disabled

On the Do-It-Yourself-website it is possible to enable and disable roaming user profiles for the domains NWI and B-FAC. The default is to use roaming profiles for the NWI domain and not for the B-FAC domain. In general logging on and off will be a little bit faster without using a roaming user profile, but a disadvantage is that user settings will not be saved. Examples of user settings that wil not be saved are the Desktop backgound image, documents stored on the Desktop, Email settings, 'Favorites', 'Recent Documents', etc. Without a roaming profile documents that are placed on the desktop will not be saved!

Ron Sommeling 23 mrt 2010 14:48 (UTC)

Linux cups server and printing using Kerberos tickets

To print from Linux to a budgetted printer you had to type your account password for every print job. Sometimes this was problematic if the application was not started from a terminal window. Now there is a CUPS-server drukwerk.science.ru.nl which demands a valid Kerberos ticket, so you do not need to type your password for every print job. Managed Linux PCs running Fedora 8 and above already use this CUPS-server. A Kerberos ticket granting ticket can be obtained by typing kinit.

We will try to extend this CUPS-server in such a way it can be used for Windows IPP-printing.

Ron Sommeling 23 mrt 2010 09:55 (UTC)

New pc's in pc rooms dual-boot Windows/Linux

All new pc's in the pc rooms and study landscape are dual-boot: an individual student or employee can choose to start Windows-XP or Linux Fedora 11. The rooms can now also be used for courses that require Linux. Only the older pc's in TK075 (HG00.075) are still single-boot Windows-XP. In the course of 2010 the migration to Windows 7 and Ubuntu 10.04 Linux will start.

Wim Janssen 23 mar 2010 09:35 (UTC)

Old pc's for sale to Science employees and students

In January, all 5 year old pc's in pc rooms and study landscape have been replaced by new ones. Departments of the Science Faculty have already had the opportunity to express their interest in these old pc's. C&CZ still has a few dozen left, which are now offered to individual employees and students of the Science Faculty, almost without any guarantee. When interested, contact C&CZ (Helpdesk, Theo Neuij/Mathieu Bouwens, 20000). Specifications: Dell Optiplex SX280; Pentium 4 dual core processor 2.8 GHz, 1 GB RAM, 80 GB hard disc, including (attached) 17" TFT-flatscreen, keyboard and mouse.

Theo Neuij 12 mar 2010 18:15 (UTC)

Web application for employee attendance

Within various service departments of the Faculty of Science, a web application for employee attendance (time registration) is used. This application is based on the open source system TimeTrex. Other departments that are interested in using the system for one or more employees, should contact C&CZ. Registration is done with passes or on the web. It can be helpful for the administration of variable working hours. It is a somewhat flexible system, that e.g. can also be switched to automatically register attendance, which makes it into a (sick) leave registration system. There is no interface (yet) with the RU BASS-HRM registration of (sick) leave, which has to be updated at least quarterly.

Astrid Linssen 12 mrt 2010 16:25 (UTC)

Opening hours C&CZ changed

C&CZ can't maintain the opening hours that were extended in 2008, our new opening hours are from 08:30 to after 18:00.

Peter van Campen 5 mrt 2010 16:50 (UTC)

Saving time when making appointments (manage calendars)

If you spend a lot of time planning appointments, especially with stable and/or big lists of employees, please read on.

The last few weeks, the Faculty Office succesfully tested the Mozilla SunBird calendar software. At this moment, with this software one can view the free/busy information of a few dozen employees that are using Outlook, Google Calendar or a Science Faculty E-Groupware calendar.

If you are interested in using this calendar software, we would like to hear from you, with a list of persons with whom you most often make (group) appointments. These persons can change their calender settings themselves.

Radboud University intends to migrate in 2010 to a modern mail/agenda system for all employees and students. This system can be used with a nice webclient, but also with Outlook, Thunderbird etc. This should make planning appointments with RU employees really simple and efficient. If you can wait for this new system, you do not have to react of course.

Peter van Campen 4 mrt 2010 16:05 (UTC)

Endnote X3 available

Endnote version X3 is available for MS-Windows and Macintosh. It can be installed on Windows from the install network disk. The CDs can also be borrowed by employees and students, for home use too. It has also been installed on the Windows-XP Managed PCs.

Ben Polman 3 mrt 2010 17:09 (UTC)

Office2007 and Learning Guide

Departments that would like to migrate from Microsoft Office XP to 2007 with their Windows managed pc's can send a request to C&CZ. To help users with this migration, Radboud University has bought a Learning Guide (in Dutch), that can be used from the campus network. The guide also contains information on Windows7.

Ben Polman 3 feb 2010 17:12 (UTC)

BASS on Mac and Linux

The use of the BASS (Oracle) concern applications for HRM and financial transactions is supported only on some Windows platforms. However because BASS is essentially a Java application running from a browser it should function just as well from other platforms such as Macs and Linux systems. Indeed we were able to place an order through BASS from a Linux (Fedora 11) system and we've heard that for some people BASS also works from a Mac. For those who are not afraid to experiment a little we have collected a few hints on our BASS page which may help you to get things going.

Replacement of pc's in pc rooms

In the third week of January, in total 122 pc's in pc rooms TK149/TK153, Biology Lab TK329 and the study landscape will be replaced by new ones. The inconvenience for students will be minimal in this week. Departments can contact C&CZ (Theo Neuij, 56666) if they are interested in acquiring a number of these more than 5 year old pc's.

Theo Neuij 7 jan 2010 15:07 (UTC)

PCs in the Library of Science accessible by all RU students

As of December 23, 2009 all students of Radboud University can logon to the PCs in the Library of Science in the Huygens building with their RU account (s-number). Make sure to choose the RU logon domain at the logon screen.

Please Note:

  • Personal configuration settings are not preserved between sessions on these PCs.
  • Only the black-and-white printers in the vicinity of the library are automatically available. Other printers need to be configured manually for each session. For instructions please come to the library front desk.

FNWI students and staff can also logon with their science account (domain B-fac), yet without their personal profile. However, the U-network drive with their personal data is available. On PC's in the terminal rooms the personal profiles are still available.

In January the PCs in the Studielandschap will be replaced by brand new hardware. The new PCs will be accessible by all RU students.

New Comodo certificates with Windows Mobile 6.1 problem

The new Comodo certificates, that were announced in May, are gradually being used by RU-servers. The expectation that these certificates would be "popup free", has not been completely fulfilled: users with a Windows Mobile 6.1 smartphone are advised to check the presence of the Comodo SSL root certificate. Without this root certificate, usage of the secure wireless network or secure RU-websites will become impossible.

Ben Polman 23 dec 2009 16:40 (UTC)

F-Secure: new version, less system impact

Version 9 of the F-Secure security software is available on Radboudnet. The new version has less system impact. The RU-license encompasses home use by employees and students. In January 2010, C&CZ will start deploying this version on the C&CZ-managed MS-Windows pc's.

Wim Janssen 23 dec 2009 14:13 (UTC)

Backup tape robots upgraded

C&CZ has upgraded its two 5 year old LTO2 (200 Gb/tape uncompressed) 8-Tape Library units to two LTO4 (800 Gb/tape uncompressed) 24-Tape Library units. We named them R2D2 and C3PO. This upgrade not only increases the backup capacity by a factor of 12, which is necessary because more and more data needs to be backupped. It also speeds up the backup and restore times because the drives are faster and the manual operational overhead is reduced.

In the near future we will be looking for a new destination for our old but still trustworthy LTO2 units. If you are interested please mail to postmaster at science.ru.nl.

Caspar Terheggen 23 dec 2009 15:48 (UTC)

Troosterprijs 2009 to Remco Aalbers

The Trooster Award 2009 has been awarded to Remco Aalbers. One of the systems he developed is the web application RUMBA (RU Master Bachelor) for creating and consulting course information. Some other highlights of his work: the education pressure report system ROB, the experimental student portfolio, the Virtual Classroom for Biology and the wiki’s. The presentation of the award was Friday December 18, 16:00 hours in HG00.304. In his presentation Aalbers didn't expand on the developed systems, but explained his method of development: Agile software development of web applications based on open standards and open source.

Valid e-mail in Spam folder

On 7 december, during the regular update of the spamfilter, a new filter set turned out to tag too many valid messages as spam. Therefore some valid mail ended up in people's Spam folders, so-called false positives. Please search your Spam folder (a subfolder of Inbox) for false positives. It is advisable to do so once a week even under normal circumstances if you do not want to miss any mail, but for December 7 and 8 there is a direct reason to do so.

Additional information on our virus and spam filtering and the personal settings, is available.

We apologise for any inconvenience this may have caused.

Power outage in computer room

On December 13 2009 at 18:50 we suffered a power outage in our computer room *behind* the UPS, that is meant to shield the servers from problems with the electricity grid. The UVB investigates the cause of the problem. The outage caused the failure of several file servers, web servers (including squirrel), one of the LDAP servers, etc. All systems have been reconnected to a different power supply and at 10:20 all systems were started. In the next hour all services should become available again.

Caspar Terheggen 14 dec 2009 09:24 (UTC)

Linux print problem and change

The FSR reported a security problem with printing on Fedora Linux, that made it possible to print using the budget of a different user. As a temporary emergency solution, one has to supply a password when printing login server, like lilo and stitch, to a budgeted printer. See the print information to print from within an application that doesn't ask for a password. A final solution, the deployment of a central CUPS-server, couldn't be realized in a very short timeframe. Thanks to the FSR for reporting this problem.

Ron Sommeling 19 nov 2009 13:53 (UTC)

Linux login servers: upgrade and addition

The operating system of the general purpose Linux login server lilo (formally porthos.science.ru.nl) has been upgraded to Fedora 11. Also a second Linux login server named stitch (formally lijfwacht.science.ru.nl) is now available. Lilo and stitch are identical as far as the software is concerned but stitch has newer, more powerful hardware (8 cores, 2.5 GHz each, 8GB internal memory). In case of a problem with one of these servers the other one serves as backup. These changes were initiated because of a security issue on lilo before the upgrade and agree with our goal to eliminate the old Solaris login servers solo and solost eventually. For more info, see the servers page.

Caspar Terheggen 19 nov 2009 13:19 (UTC)

BASS update locally managed pc and downtime

If one uses a locally managed pc, one should update BASS before November 9 to avoid problems. The C&CZ Managed Windows pc's are or will be updated by C&CZ. This update is necessary to use the new BASS servers. Because of this update, BASS cannot be used between Friday November 6, 12:00 hours and Monday November 9, 08:00 hours.

Peter van Campen 16 okt 2009 14:53 (UTC)

Internet domain name registration/relocation

C&CZ has recently obtained a partner account at domain name registrar QDC, allowing us to register a .nl, .com, .org or .eu domain name quickly and easily. The (technical) administration of such a domain name is controlled by C&CZ (the C&CZ Internet domain name servers). In this way Radboud University Nijmegen becomes the owner of the domain name instead of an individual employee of a department). Relocation of existing domain names to the registrar QDC is also possible, but will involve some additional paperwork, see the domain name registration page for additional details.

Caspar Terheggen 1 okt 2009 14:58 (UTC)

Student printer changes

Next to printer jansteen another HP4350 black-and-white laserprinter jansteen2 has been placed. This makes printing easier for students: if one of these printers has a problem, one can just pick the other one. Repairs of these printers can take a long time, because there is no support contract anymore for these printers. The HP4350 printers monet and chagall have been removed.

Theo Neuij 28 sep 2009 12:05 (UTC)

PC-rooms renewed and expanded

The more than five year old pc's in PC-rooms HG00.029 en HG02.702 have been replaced by new ones. At the same time the number of pc's has been increased by 27 to accommodate the larger number of students. Both rooms are dual-boot: every pc can be used with Microsoft Windows or with Fedora Linux. By waiting for the lower prices of the standard supplier, that were a result of the European tender of pc's, thousands of euro's could be saved. The plan is to replace the other about hundred pc's that were bought for the pc-rooms in 2004, at the time of the completion of the first phase of the Huygens building, at the end of 2009.

Peter van Campen 25 sep 2009 14:31 (UTC)

New faster Ricoh printer/copier

The printer, scanner en copier Ricoh Aficio MP 5000 with the name watt is replaced by a faster B&W Ricoh Aficio MP 7000 with the name volta.

The address book of watt is largely copied to volta. Volta can only scan in B&W.

Ron Sommeling 17 aug 2009 07:10 (UTC)

Redundant fiber uplinks

From today all network switches in the Huygens building and other buildings at Toernooiveld are linked to the FNWI router by a second, redundant fiber uplink. This router consists of two linked autonomous switches at different locations. As result of this a defective fiber link or failing router switch will not instantly effect the existing network connections. Obviously an improved availability of the network services.

Fast info pc's, also for non-Science users

A few days ago a column with four pc's has been placed in the central street of the Huygens building, next to the Library of Science. Students asked for pc's to look up information fast, IHZ ordered the design of the piece of furniture, C&CZ placed the pc's. New is that also non-Science users can login with credentials from a different domain than Science, e.g. in the RU-domain with s-number and KISS-password for a student. U-number and RU-password for an employee doesn't work (yet). In order to login fast, no roaming profiles are loaded for a user. Specific Science software and printing is not possible (yet).

McAfee stops, switch to F-Secure

The end date of the earlier announced license for McAfee security software, September 1, 2009, comes nearer! On the Windows Managed pc's McAfee is step by step being replaced by F-Secure, starting with PC-rooms and study landscape. Employees and students can also use The F-Secure Client Security software at home. It can be found on the install network disk. License codes can be requested from C&CZ. Adequate security is more than just a virus scanner, see e.g. the RU ICT-security website (in Dutch) on securing and cleaning a pc.

1234567890 seconds since The Epoch

Next Saturday February 14 at 00:31:30 local time the time counter that is commonly used in the Unix world, i.e. the number of seconds since January 1, 1970 UTC ('The Epoch'), reaches the pleasing value of 1234567890. Perhaps even more exciting is the fact that in the early morning of January 19, 2038 the counter reaches the maximum value that can be stored in a 32 bit signed integer. Luckily there still is enough time to find a solution for this daunting challenge compared to which the Y2K problem was just a stroll in the park.

Again power failure server room HG04.070

Saturday Jan 31 around 03:00h the power supply fire protection unit in the server room HG04.070 was activated again, which caused the immediate and complete power down of all servers in that room. This time as well no sensor had detected a temperature high enough to activate the protection unit.

There was no extra information available to determine a more definitive cause for the immediate 'Emergency Stop' of the UPS unit.

To prevent a new faulty fire alarm event, only one (1) temporary, mechanical temperature switch, can activate the UPS 'Emergency Stop'.

The complete fire alarm power switching unit with 4 temperature senors has been disconnected from the UPS 'Emergency Stop'. This system is still working and is still connected to and monitored by the building alarm system.

It has been discovered that every door entrance has a fire-key-switch, directly connected to the UPS 'Emergency Stop'. These switches were not connected to the building alarm system. The switches are now disconnected from the UPS 'Emergency Stop' and are now connected to and monitored by the building alarm system.

This setup ensures that:

  • there still is a working fire power protection unit, be it with a only one slow sensor at one place (near the hot spot).
  • a failure in the old circuit of the door switches will be detected, but cannot cause a UPS 'Emergency Stop'.
  • it will be clear when an UPS internal problem is the cause of an UPS 'Emergency Stop'.

Depending on future alarms, new information will come available to explain power failures and their causes.

It is agreed that the current situation will remain in place for at least two months unless an alarm occurs.

Software licenses for employees and students of RU

Because there are many licenses for software, with different usage rules for employees, students, on campus and at home, the UCI published a (Dutch) news article about ordering software.

PC rooms upgraded

The last weeks almost all older PC rooms have had an upgrade. These PCs now have at least 1 GB of memory and a better MS Windows (WDS) installation. Exceptions are the too old PCs in TK702 (TK-GIS, HG02.702) and the "self study rooms" (HG00.2xx).

Power failure server room HG04.070

January 20, around 10:45h, the power supply fire protection unit in the server room HG04.070 was activated, which caused an immediate and complete power down of all servers in that room.

Through bypassing the protection unit, power could be switched on again, first partially and fully functional again about 12:00h.

Then the fixing hardware and software problems resulting from the immediate shutdown could be started. This took several hours for some systems. Work on the student file server lasted until the morning of January 21.

Around 18:00h the protection unit was activated again with a larger margin for the room temperature.

Department contacts instead of first line contact (person)

The title "first line contact (person)" for contacts for C&CZ in the departments of the Faculty of Science was often misinterpreted by people elsewhere because the term "first line support" in general is associated with the ICT support groups. Therefore on the C&CZ wiki the term "department contact" is now used instead.

Tracelab: ordering and keeping track of chemicals

Due to ever more stringent rules for ordering and keeping track of chemicals, the intention is to only order chemicals through Tracelab from January 1, 2009 and therefore reject orders for chemicals that are directly entered into BASS Finlog.

Outgoing mail spamfiltered

As of today mail which is recognized by the Science spamfilter as being spam is not sent to external mailservers anymore, but saved to a central quarantine folder. This change in the behaviour of the Science mailservers was necessary because those servers otherwise ended up in a blacklist. The forwarding of incoming mail thus gives a filtered mail feed from now on.

Causing trouble for colleagues by reacting to phishing mail (mail asking for password)

A week ago a too naive colleague reacted to a phishing mail by sending his loginname and password. Soon after that loginname was misused to send large amounts of spam through our webmail server, which lead to the appearance of one of our servers in a blacklist. That made it impossible for that server to send mail to some organisations. C&CZ likes to stress *again* that it is not very wise to believe something just because is written in a letter or e-mail and that *no official institution* will ever ask you for your password, just like a bank never will ask you for your pincode for your bank account.

Matlab: TIMEOUTALL introduced, installation procedure changed

After an idea from FC Donders, C&CZ changed the options for the Matlab license server to include a 'TIMEOUTALL 3600'. This has the advantage that an inactive user can hold a license for Matlab or a toolbox for 1 hour at maximum, but could cause problems sometimes for the many tens of users within Radboud Unicversity and Hospital, because it can happen that a long-running Matlab job stops because there is currently no license available.

Removing old mail addresses helps prevent spam

At this time (May 2008) we often see that suddenly a lot of spam is sent from different places on the Internet, with a (fake) sender address of the old "@sci.kun.nl" form. For the owner of such an address this gives some trouble, since the spam that cannot be delivered wiil come "back" to the sender address that was used. To help prevent this, it is a good idea to look in the DIY website which old "kun.nl" addresses can be removed and mail that to postmaster.

Network upgrade successful

Sunday morning April 20 between 09:30 and 11:30 hours the router/switch that couples the networks on the Toernooiveld with each other and with the rest of the RU campus network (and by that with Surfnet/Internet), was replaced by a new, more powerful machine. The work was planned by C&CZ en UCI to cause minimal trouble for employees and students.

The next few weeks other changes to the network will be made, but the trouble this will cause will be much less.

Some aspects of this upgrade: 1 router/switch that is spread over 2 locations, with 10Gb uplinks to the UCI. The router/switch can provide better protection since it has more room for "access control lists"and by using "reverse path forwarding". By using FlexLinks desktop switches can easily be connected redundantly. Cascades of desktop switches can be split, since more interfaces are available. Also antique connections to remote locations can be upgraded.

About the new network (NiNe) the UCI reported in the Enter magazine

RU now victim of phishing scam too (mail asking for password)

Now also a lot of RU employees received emails, that at first sight looked as if they were sent by a RU Helpdesk, in which was asked for a reply with loginname and password. The reply of a naive user again went to a "@hotmail.co.uk" mail-address. C&CZ likes to stress again that *no official institution* will ever ask you for your password, just like a bank never will ask you for your pincode for your bank account. This is almost an exact copy of the incident with TU Delft that C&CZ reported on January 29. If someone was unwise enough to reply with username and password, then it is wise to change the password immediately.

TU Delft victim of phishing scam

The CERT-RU, that coordinates security incidents within the RU, reported that employees and students of the TU Delft had received emails, that at first sight looked as if they were sent by TU Delft, in which was asked for a reply with loginname and password. The reply of a naive user went to a "@hotmail.co.uk" mail-address. C&CZ likes to stress that *no official institution* will ever ask you for your password or pincode for your bank account. For the original message of the CERT of TU Delft, see TU Delft Security Alert.

Acrobat Reader, new version with problems

On all Managed PCs version 7 of Adobe Reader has been replaced by version 8.1.1, because of a security hole. The upgrade lead to several problems:

  1. Printing from Adobe Reader to a HP4250/HP4350 printer doesn't work. According to Adobe this is a fault of the software in these HP printers. As an alternative one can use the dali printer in HG00.201 or one of the colour printers (HP or Tektronix). The Ricoh multifunctional copier/printer/scanners that will be placed soon in several locations to replace the Oce copiers do not have this problem.
  2. PCs with a license for Adobe Professional do not (yet?) have a license to upgrade, but having Adobe Professional version 7 and Reader version 8 at the same time doesn't work.

Matlab nieuwe versie (R2007a)

Met ingang van mei 2007 is er een nieuwe versie (7.4, R2007a) van Matlab beschikbaar op alle door C&CZ beheerde PCs met Linux of Windows-XP en Suns met Solaris.

De oude versie (R2006b) wordt over enkele weken verwijderd, wanneer duidelijk is dat de overgang naar R2007a geen grote problemen veroorzaakt. Om de oude versie tot die tijd nog te kunnen gebruiken moet het zoekpad uitgebreid worden met /vol/matlab-R2006b/bin (onder Unix).

Voor meer info over deze release, zie [de Mathworks website]

Donderdag 5 oktober (week 40) om 16:30 zal het active directory domein van alle door C&CZ beheerde Windows XP Beheerde Werkplekken en Windows servers worden hernoemd van nwi.kun.nl naar nwi.ru.nl. Belangrijk is om op de betreffende donderdag voor 16:30 uit te loggen, maar de beheerde Windows XP PC *niet* uit te zetten. Tussen 17:30 en 00:00 zullen alle Beheerde Werkplekken die aan staan 2 maal gereboot worden. Lees a.u.b. de domain rename instructies door. Dit bespaart veel onnodig overlast en werk.
