Again power failure server room HG04.070
Saterday Jan 31th 2009, at night around 3:00h 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 define 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 doorentrance 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 to the UPS 'Emergency Stop' and are now connected to and monitored by the building alarm system.
This setup ensures that:
- the 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 be in place for at least to months if any alarm fails to occure.

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. A lot of information about software (licenses) can also be found through the C&CZ softwarepagina, e.g. about software for computers running Microsoft Windows.

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 serverroom 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.

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.

Firefox: new version
On all managed pc's the latest version of Firefox has been installed including the NoScript plugin. NoScript initially forbids execution of all scripts on a webpage. Per website one can decide to allow scripts temporarily or permanent. This is an excellent tool to minimize the risks of using websites.

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. This holds for all units of the Faculty of Science (in the Research Tower as well) and for all users who are located in the buildings of the Faculty of Science (hence also the spin-offs).

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.

Phone Guide RU updated automatically
The interface between the Science phone guide and the RU Relation Management System (RBS) and through that with the phone guide is working now. That means that the guides will automatically be updated when the telefone contact person (usually the secretary) of a department within the Science Faculty logs into and updates the Science Phone Guide website. In the Science Phone Guide one can also enter information of labs, elevators, secretariats etc., only the data for a U-number will end up in RBS. For more information see the Telephony page.

Reporting repairs/problems through the helpdesk website
Since a few months several employees and students use the C&CZ helpdesk website to request repairs and report other problems. One has to login on the website with the Science login name. Advantages are that if the machine is known, like with a Managed Workplace PC, one doesn't need to fill in serial numbers and that one can follow the actions for the repair through the website.

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.

H:-disk of students moved and enlarged
Because of the new computer lab TK023 with dual-boot Windows/Linux PC's, the H:-disks (home directories under Linux/Unix) of students have been moved to a new server. This made it also possible to enlarge the quota on that disk to 1 GB per student.

New computer lab TK023
A new computer lab TK023 (HG00.023) is available, with 41 modern PC's with big 24" screens with high resolution. For C&CZ this is a new type: the user can boot Windows-XP as well as Fedora Linux. Such a dual- or multi-boot PC is the standard for the future for the computer labs, with in the future almost certainly also Windows-Vista next to Windows-XP.

Critical security flaw in Adobe Acrobat t/m versie 8.1.2
Adobe Acrobat has a critical security flaw, all users of version 8 are recommended to update to version "8.1.2 Security Update 1". Since the site-license for Adobe software has finally come through, this update can probably best be combined with the update to the Professional version.

New version of the Windows Managed PC
There is a new installation method for the Windows-XP Managed PCs, that has been developed and is being maintained by several IT-support groups in the RU tohether, in the SITO (Samenwerkende IT-Ondersteuning) project. The main difference is that more software is installed, and that it is less dependent on network drives. Many PCs in the Study Landscape and several departmental PCs have been installed with the new method.

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.
With Matlab version R2008a the Matlab installation procedure has been changed.

Adobe Flash Player Security Vulnerability
Last week word was spread about abuse by installing keyloggers through a security vulnerability in the Adobe Flash plugin of browsers like Internet Explorer and Firefox. C&CZ managed computers have been updated to the latest version. C&CZ advises everybody to upgrade to version 220.127.116.11 if not already done. Testing can be done through the Adobe testpage and holding the mouse above "About". For even more browser security one can quite easily install the Firefox extension NoScript.

A CD of MS Office 2008 for Macintosh can be borrowed for campus use and on Macs owned by departments, the NL- as well as the UK-version. For home use one can buy it relatively cheap at Surfspot, althoug it is always more expensive than the free OpenOffice.

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.
