[ISG News] Partial Network Downtime on Mon 6th Dec after 19h00
by Claude Becker 29 Nov '21

29 Nov '21

ISG News has posted a new item, 'Partial Network Downtime on Mon 6th Dec after 19h00' The central Informatikdienste will have a scheduled downtime of all networking (cable and wireless) in the buildings HPK, HEZ, HPM, HPL and HPW on Monday 6th Dec 2021 in the evening between 19h00 and 23h00. This is the second of three downtimes for the ongoing project to split the current networks into smaller chunks. This major undertaking will also induce a short downtime for some computers in the dynamic DHCP pool in other buildings (as some of our IP ranges are being moved to the listed buildings). Users don’t need to do anything and their computers should come back online automatically. Otherwise try to reboot or get in touch with us. In order to prepare for the migration, Informatikdienste will forbid all changes to their DHCP servers between Friday 3th Dec 13:00 and Tuesday morning. As a consequence we will not be able to register new devices or hostnames during this period.

[ISG News] Emails erroneously flagged as spam

24 Nov '21

ISG News has posted a new item, 'Emails erroneously flagged as spam' Between yesterday Tue 23rd Nov 07:27 and tonight Wed 24th Nov 01:48 several hundred emails have erroneously been flagged as spam by our mail server. Please check your SpamBox folder for potential false positives during that period. While we are constantly updating our filtering rules to catch the nasty spam, we are always doing our best to avoid flagging real emails as spam. We apologize for this and are still investigating the details of the root cause. Because the bulk of the messages were being correctly delivered, it took us several hours before we noticed the problem and could fix it.

[ISG News] Rethinking groupware
by Christian Herzog 12 Oct '21

12 Oct '21

ISG News has posted a new item, 'Rethinking groupware' In August of 2010, we introduced our groupware solution for D-PHYS. In the last 11 years the system has served the Department well, but we believe now would be a good time to think about the future of groupware at D-PHYS. Here's an incomplete list of things we noticed over the years: the groupware system seems to get used almost exclusively as a calendar for distributed calendars, the world and people's expectations have changed file and sync formats have come and gone 17 people will have 634 completely orthogonal and incompatible use cases for calendars the product that won our evaluation round in 2010 is not necessarily the best system for 2021 We have sampled the market and test-installed several candidates, but since our humble ISG-internal calendar only covers one very specific use case, we strongly encourage you to give us your feedback so that the next D-PHYS calendar solution will suit you well. In particular, we're interested in learning are you using any other egroupware module(s) aside from the calendar? If you don't tell us about it now, a potential replacement may not have this functionality! what's your current calendar use case? Just a personal calendar? A group calendar? In which configuration? what's your desired calendar use case? This might be the most interesting thing to learn... which sync protocols/devices are you using? what other software/products/services have you been/are you using? If you would like to help make sure the next evolution in distributed D-PHYS calendars is a success, please join our Matrix room and participate! Thanks a lot.

[ISG News] D-PHYS network migrations
by Claude Becker 07 Jul '21

07 Jul '21

ISG News has posted a new item, 'D-PHYS network migrations' Several network migrations will take place over the next months that will have an impact on the design and inner workings of the ethernet network at D-PHYS. Even though all hosts will be affected at a technical level, we believe that most changes will not require any involvement from your side. By the end of the year this should further increase the fault-tolerance of the cabled network infrastructure and enhance the security of the bulk of the computers at D-PHYS. Network segmentation The central Informatikdienste are splitting several networks into smaller chunks to increase the overall stability and fault-tolerance. Unfortunately the details are flagged as confidential, prohibiting us from exposing the precise structure of this segmentation. The main repercussion is that our D-PHYS networks will no longer be able to span across all current buildings at once. So depending on the building, we will have to introduce new subnets and assign new IP addresses to the computers inside. NAT network Motivated by the above-mentioned segmentation as well as security considerations, we are planning to migrate a large number of hosts to a NAT network. This means that the computer will only get an ETH-internal IP address and will no longer be directly reachable from outside of ETH. From inside ETH or VPN, all communication with that computer remains unaffected. However, while the host can still communicate with all of the internet, it will no longer be exposed to direct attacks from the outside. We believe that this is a very sensible default for most computers and laptops. Of course it will still be possible to assign a public IP to selected hosts in order to provide a specific service to the outside. The new NAT network also provides DynDNS with sentname.dhcp-int.phys.ethz.ch hostnames and full IPv6 connectivity. So if you rely on DNS entries for dynamic IP addresses, make sure to use the domain dhcp.phys.ethz.ch for public subnets and dhcp-int.phys.ethz.ch for internal subnets. DHCP migration Right now, some of our networks are serviced by our own D-PHYS DHCP servers, while others use the DHCP servers of central IT services. We are now consolidating all networks and migrating the remaining ones step-by-step to the DHCP servers of Informatikdienste. This change is mostly technical and should remain unnoticed by most users. For further details and up-to-date information please refer to our readme page.

[ISG News] New Microsoft Licensing terms
by Christian Ringger 28 Apr '21

28 Apr '21

ISG News has posted a new item, 'New Microsoft Licensing terms' Last year, the license agreement between ETH and Microsoft has changed. There are some new terms and conditions which are important if you use a Microsoft product from the ETH IT Shop. If your hardware came with Windows preinstalled from the hardware vendor, you have your own license for MS Office, or you are using non-Microsoft products like Libre Office, then you are not affected by this new license agreement. No further action is needed in this case. However, if you use any of the following software products from the ETH IT Shop you have to take action: Windows 10 Education Windows 10 LTSC MS Office XXXX (for example MS Office 2016) Microsoft 365 Microsoft Teams ETH Exchange Mail (mail.ethz.ch) either on a managed Windows workstation from ISG or a self-managed workstation or notebook. In this case you need to request access for a free Microsoft Cloud Subscription in the IT Shop. See here for instructions. If you already use MS 365 or MS Teams, maybe you already have the Cloud Subscription and no additional step is necessary. This can also be verified in the IT Shop. Remember that you need renew the subscription every year. The new Microsoft license agreement allows only 1 MS Office XXXX (for example MS Office 2016 or Office 2019) installation per user. If you need installations on multiple computers for example in labs, use MS 365 instead. Note that you will have to take action if you're affected. You cannot sit this one out. The Informatikdienste license team will be coerced by Microsoft to enforce license compliance, and they will contact you if you don't get your Cloud Subscription. If you have any questions, feel free to contact us in our Matrix chat #D-PHYS ISG Helpdesk or by email isg(a)phys.ethz.ch Thank you for your attention, and kind regards.
