DHCP Server Upgrade on Wednesday 5pm

On Wednesday, the 6th of April 2011, starting around 5pm we will upgrade the operating system on the two D-PHYS DHCP servers. This should not cause any interruptions for computers which are already online, but computers which connect to our network between 5pm and 6pm may not get an IP address assigned immediately. As these computers mostly will be mobile devices, we suggest to switch to the wireless network instead for that evening.

New print server

New feature in our helpdesk system: ticket tracking

Computer support during christmas holidays

The ETH Zurich will be officially closed between Friday, 24th of December 2010 and Sunday, 2nd of January 2011. During this time, we can only provide limited support. Please follow these rules to save us from superfluous work:

  • Switch off printers
  • Switch off your personal workstation and notebook except for the following:
  • Do not switch off our managed Linux workstations.

We will try to follow our e-mail, but you may also have luck and meet some of us in our IRC channel.

New SSL and HTTPS certificates for many ISG D-PHYS services

In the past all HTTPS secured web sites hosted or provided by us used certificates issued by ourselves. This caused unsettling warnings in most browsers as the user had to manually add the root certificate of our certification authority (CA) to his web browser.

To allow SSL certificates other than those signed by ourselves, namely certificates automatically accepted by all browsers, but also community-backed CACert certificates issued by ETH ID, we will change the configuration of our web server zwoelfi this evening. This may cause some short interruptions to some of the hosted sites, but should not be of longer duration.

Some of these web sites will get already new SSL certificates issued by QuoVadis (accepted by nearly all browsers by default) this evening.

Update Friday, 1. Oct. 2010, 21:00h: Due to several unexpected issues with the new QuoVadis certificate, for now the webserver runs again with the old ISG signed SSL certificate on all virtual hosts.

Update Thursday, 7. Oct. 2010, 23:00h: Most of the issues with the new QuoVadis certificate are solved now and all virtual hosts planned for the QuoVadis SSL certificate use it now again.
