Nearing End of Life support for Windows 2000 and Windows XP SP2

Monday, March 8th, 2010

On July 13th 2010, Windows 2000 Server/Professional and Windows XP Service Pack 2 will no longer be supported with security updates by Microsoft.

Machines running these operating systems should be upgraded to newer versions like Windows 7 or Server 2008 if they are directly connected to the D-PHYS network.

The IT Use Policy of ETH does not allow systems without an active patch cycle to be connected to the ETH network.

Please make sure that all computers running any of the affected operating systems have been migrated by July 13th 2010. The same also applies to even older systems like Win 9x or NT 4.0 of course.

Short maintenance downtimes of Terminal, Mail and Authentication Server

Friday, December 4th, 2009

There will be a semi-urgent maintenance reboot of our mail server and our terminal server “plimpy” today, Friday, 2009-Dec-04, at 6pm. So if you are using one of our thin clients, please save your work and log out before 6pm. Expected downtime durations: approximately 15 minutes for the terminal server “plimpy” and approximately 30 minutes for the mail server.

Additionally there will be a restart of our LDAP authentication database at the same time. This can cause logins on managed workstations or connections to file servers to fail temporarily, but should take no more than a minute or so.

Update, 7pm: Maintenance over. All systems back to normal. Terminal server was back in time, mail server needed a file system check so the downtime took slightly longer than expected. LDAP restart was a matter of seconds.

Linux kernel local privilege escalation

Tuesday, August 18th, 2009

In case you’ve been wondering about the slightly dubious announcements of the past few days: on Friday (2009/08/14) a local privilege escalation in all Linux kernels of the last 7 years was published, together with an exploit. Unfortunately no patched kernels were available by Friday late afternoon, which put us into an awkward position. Generally it is not our policy to be sneaky about security issues, but in this case we really did not want to attract malicious script kiddies. That’s why we decided to keep our announcements somewhat vague. By now the worst seems to be over and all machines have been rebooted with patched kernels.

We apologize for any confusion or service degradation this episode may have caused on your side.
