Windows wi-fi exploit (Intel Centrino)

Several sites (SANS, stateofsecurity.com) mention a new exploit for Intel Centrino wireless network cards, commonly used in laptop computers. Driver updates from Intel have been available since January, 2007.

New storage possibility for passing on large files

To facilitate the local copying of large files (for which mail is not suitable) a new network share is available, see TempDisk.

Temporary compute server will be shut down Monday April 28

The "t4150" test-machine with 4-core Intel processors (Sun Fire X4150, E5345 CPU's) will be shut down on Monday April 28. We'll conduct a hardware RAID-test and re-installation of the OS. After that, the machine will be shipped back to Sun.

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

Printbudget command for Unix

On Linux/Solaris workstations and login servers one can use the command printbudget to get an overview of the budget groups and the money on it. One can also change the default budgetgroup and get an overview of the last print jobs, like it is on the Do-It-Yourself website.

Power problem April 10/11

Thursday evening April 10 at 21:30 a power glitch for wings 1 and 2 of the Huygens building caused power switches to triple. Thanks to a UPS in wing 1 the router and network switches kept on running until 22:30. The UVB fixed the power to the router and swityches in wing 1. Power to the switches in wing 2 was not fixes until 10:00, which made the problem last the longest in wing 2 and the eastside of the central street between wings 2 and 4 (no network). C&CZ will contact the UVB to try to give more priority to restoring power for network equipment.

MS Office for Mac 2008 can be borrowed

Disk quota for students enlarged

The standard disk quota for students have been enlarged to 400 MB. Students can thus save more files on their homedirectory (H: disk) which, hopefully, lets them store less files on their Desktop (or anywhere else in their profile). A large profile makes log-in and -out slow.

New disk server with 90 GB partitions

New disk-servers are available with partitions of 90 GB that can be rented by departments of the Faculty of Science. The older RAID-arrays were sold out, one of them had run out of maintenance. The new servers have internal disks and controller. The partitions of the out-of-maintenance RAID-array will be moved to a new server.

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. C&CZ will contact users that sent replies through a C&CZ mailserver and has blocked mail to the "@hotmail.co.uk" mail-adres in question on their smtp-servers.

SURFnet/Internet connection down Monday April 7 18:00-22:00 hours

The UCI will again try to upgrade the connection between the RU and SURFnet next Monday evening from 1 Gb/s to 10 Gb/s. The connection between RU and SURFnet will be interrupted during the maintenance. C&CZ will plan the upgrade of the FNWI router to 10 Gb/s afterwards.

MS Office 2007 Multi-Language Pack available

The CD and 2 dual-layer DVDs (13 GB in total) of the MS Office 2007 Multi-Language Pack can be borrowed for campus use.

Peter van Campen 3 apr 2008 18:57 (CEST)

Windows Vista 64-bit DVD available

The 64-bit version of MS Vista Enterprise upgrade can be borrowed for campus use, although C&CZ advises not to use this version due to possible problems with drivers, network printers etc.

SURFnet stops Usenet News service?

In the RIO-meeting of March 27, the UCI announced that SURFnet in the future would stop the Surfnet Usenet News service unless universities paid ca 12 k€/year for it. If somebody thinks this service is important for their work and that one cannot simply use an alternative like Google groups, one should contact C&CZ.

Acrobat Reader 8 problem update

Because Acrobat Reader 8 for MS-Windows produces PostScript that the HP LaserJet4250/4350 printers can't handle, C&CZ switched to using the (slower) PCL-drivers. Also FoxIt_PDF_Reader has been copied to the S disk as an alternative for Acrobat Reader.

Wireless network settings for mobile devices

For smartphones or PDA's with Windows Mobile we now have an installation manual to get connected to the wireless network. In order to connect the iPhone or iPod Touch to the RU campus wireless network, Apple would have to come with a newer software update than version 1.1.3 of January 2008, containing support for WPA-Enterprise 802.1x.

Wireless network Huygens building full coverage

In the Huygens building a wireless network with full coverage was realized shortly after the building was finished. Measurements over a long period have determined that about 25 of the 90 access points can be removed, so they can be used in different locations within the RU. Full coverage is still guaranteed.

PhpMyadmin, new version because of security fixes

PhpMyadmin is a webapplication to maintain mysql databases, all mysql databases hosted by C&CZ can be maintained through http://phpmyadmin.science.ru.nl . The new version (11.2.2) fixes a security leak [2].

Ben Polman 29 nov 2007 10:28 (CET)

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.
