Starting in mid-August, we will migrate the OS of all managed Linux workstations from Ubuntu to Debian during summer/fall of 2024.

The exact migration dates for specific workstations will be coordinated individually in close collaboration with the respective user(s). Please note that due to the complexity of the migration it is not possible to delay this indefinitely. The migration is mandatory for all Ubuntu workstations (incl. older 20.04 Focal).

Hardware owners and users are asked to check the required steps before the migration [1] now, which includes possibly needed hardware upgrades.

All users should be aware of the (breaking) changes [2] introduced with the new setup.

Please also refer to our readme page on why [3] we do the switch to Debian.

Beta test

Please get in touch with us if you have a spare workstation to participate in beta testing, starting now. Note that any such workstation will be reinstalled again in August 2024 after completion of beta testing.

Update 27.11.: We now have the migration dates and final printer list here

As you might have read elsewhere, ETH will consolidate its printer fleet for cost cutting reasons. Even though at D-PHYS we already have a very efficient printing landscape, ID will enforce a uniform 30% cut across the board. We have tried to limit the impact as much as possible and still ensure a fair and even printer distribution throughout D-PHYS, but the implications will be felt by everyone.

• 30% of all existing printers in D-PHYS will be dismantled.
• All remaining printers will be replaced with HP hardware.
• All those will get new generic queue names (like p-hil-hp002) that bear no indication as to the printer's location in the building.
• Everybody will have to reinstall all printers they'd like to use in the future.
  • on managed workstations we will prepare this as much as possible.
  • on self-managed machines you'll have to follow our instructions.
• This might be the perfect opportunity to switch over to the universal card-ethz queue that will let you forget about queue names (you can do that already now).
• We understand that for some of you this change will significantly affect your daily work. We urge you to PLEASE not try to solve the problem by buying your own printer. Instead, please get in touch with me (Christian Herzog) so that I can collect your complaints and forward them to the person responsible for this change.

The whole process is supposed to happen in December and will be rolled out building by building. We're posting this already now as individual printers in D-PHYS have already been replaced.

We will update this post with updates as they become available.

Scheduled maintenance will be taking place on our group-data.phys.ethz.ch server on Wednesday, June 7, starting at 16:00. The service will be down for approximately 4 hours. We will be replacing some hardware and upgrade the base system.

All group shares will be affected except IPA, IGP and Galaxy.

For emergency cases, you'll have read-only access to the backups as described here.

Some of you make use of our DynDNS infrastructure that automatically assigns hostnames to computers with a dynamic IP address. This feature enables you to connect to your computer using its sent hostname, followed by the dhcp.phys.ethz.ch domain (eg example.dhcp.phys.ethz.ch) instead of the ever-changing dynamic IP address.

Thursday morning

Jan 30 2020 between 9:00 and 11:00

we will be migrating our DynDNS service to the servers of central Informatikdienste. As a consequence the resolution of example.dhcp.phys.ethz.ch to its dynamic IP address may not always work during that time. The global phys.ethz.ch and ethz.ch domains are not affected. Therefore the bulk of our users will not even notice the migration.

Update: Informatikdienste have postponed the migration from 23rd to 30th January.

Adobe has forced ETH to move from impersonal serial numbers to Adobe Cloud accounts, linked to your full name and personal @ethz.ch email address. All previous installations will stop working after November 30th 2019. ETH encourages users to switch to one of the many alternatives to Adobe software. You may also consider using the free Adobe Reader to open PDFs, as many don't need the features of the paid Acrobat Pro. If you really need to keep using Adobe software, you have to migrate to the new personalized license. The detailed usage conditions and disclaimer regarding the Adobe Cloud will be visible when ordering the software in the IT Shop.

Unfortunately the central IT services only provided the new installers two days ago, meaning that everyone is forced to have migrated within 5 weeks. We tested the Windows and macOS installers and explain the activation and installation of Adobe programs in our readme.

Impact on managed workstations

The change in the Adobe licensing also affects our ISG D-PHYS managed computers. Given that all Adobe licenses must now be personal, we can no longer order the licenses for you. This, in turn, implies that we must exclude all Adobe software from our yearly software license accounting. Starting with the current 2019/2020 period, we will not charge you for Adobe products, as you will have to pay them directly yourself while ordering from the IT Shop.

All managed Windows and macOS computers will be migrated to the new Adobe Creative Cloud on

Wednesday, November 20th

In case you need to keep using Adobe software, we advise you to already order the license from the IT Shop. Starting on November 20th, you will need to log in with your personal Adobe account and install the programs, as explained in our readme. Feel free to get in touch with us, if you want us to migrate your computer before that date.

Update 08:00: Migration completed. Please note that a legacy CalDAV URL has changed - if you're using a CalDAV client (for example Thunderbird or Apple Calendar), make sure you have the correct URL according to the documentation

For our calendar solution groupware.phys we schedule a migration on Friday, September 27, starting at 07:30. The service will be down for approximately 1 hour. We will move the service to a new virtual machine and upgrade to a new version.

With the migration of the 'personal' web sites completed we're now addressing regular web shares. The easy ones have already been moved to the new web server and we're now asking share owners to prepare for migration. We will perform the migration for you, but your web site has to be ready for the environment on the new server (PHP 7 or Python 3 in particular). We're currently planning to power off the old web server at the end of 2019, so if you haven't migrated by then, your site will be offline. Please work with us to keep this deadline.

Update 10:15 - migration done, please let us know if you experience any problems.

After 11(!) years of loyal service, the current D-PHYS web server hardware will be retired in 2019 and all web sites hosted by ISG will migrate to new hardware. We will take the opportunity to reorganize the way we host web sites and improve the general setup of the web server.

In a first step, we will migrate the 'personal' web sites (those residing in public_html/ in a home directory or group share) on Wednesday, 17.7.2019. We have extensively tested the new setup, and unless you're using dynamic content in your public_html folder (like PHP or other CGI scripts), you should not notice anything. With CGIs, there's a slight chance we might have overlooked something, so please test your dynamic content after that date and get in touch if you see a problem.

The regular web sites hosted by us will be successively moved to the new hardware at a later time and we will get in touch with their owners should it be necessary.

Note that this will not affect the department website in any way as that one is hosted on the CMS of Informatikdienste.

Update 20:10 Migration finished! Everything should work as normal.

In order to guarantee sustained performance and availability of our storage system, we schedule a maintenance downtime of our home directory server on

Tuesday, July 09, starting at 17:00

This only affects the home shares (technically: smb:\\home.phys.ethz.ch & /home/USERNAME). Email and group shares will have no interruption.

Since the server also needs a file system check, the downtime will take several hours.

For emergency cases, there will be read-only access to last night’s backup as described here .

We will update this posting once the home server is back online.

The time has come to upgrade your Windows 7 computer to Windows 10
since extended support for Windows 7 ends on January 14, 2020 (Windows lifecycle).

Why can I no longer use Windows 7 on the ETH network after the end of 2019?

Only operating systems with security support by the vendor are allowed to connect to the ETH network.

• ETH Rechtssammlung, Standards für Verantwortlichkeiten und Systempflege
• IT Best Practice Rules

Unsupported operating systems that no longer receive security updates render the computer vulnerable to threats like viruses, malware or hacker attacks and also pose a threat to other computers on the network.

What should I do now?

• If you are using an OEM computer with preinstalled Windows 7 for your daily work, please update it to Windows 10 by the end of this year, at the latest. The easiest way is to use the "Microsoft Media Creation Tool" available here.
  This process is called "inplace upgrade". All applications and configuration settings should be kept.
• If your computer is installed with the Windows 7 Enterprise license from ETH IDES, order Windows 10 Enterprise from the IT-Shop and use it for the upgrade.
• If your computer is located in a lab and needs to be highly available to collect measurement data, there is the possibility to use a Windows 10 LTSC version instead of the Enterprise version. Please contact your IT administrator within your group. He should be able to help you or can get in touch with us if he needs additional help. More details about the LTSC version are described on our readme page.
• If you think that you cannot upgrade your computer, please refer to our readme for possible solutions or contact us.

Note that at some point the network security group of Informatikdienste will start scanning for remaining Windows 7 computers at which point we will be forced to disconnect them from the network.
