[ISG News] Network upgrade at D-PHYS
by Christian Herzog 23 Sep '16

23 Sep '16

ISG News has posted a new item, 'Network upgrade at D-PHYS' In collaboration with our colleagues in Informatikdienste we will use the upcoming months to upgrade the D-PHYS network in order to make it ready for the future. In particular, we will enable the IEEE 802.1x protocol in our network that will allow us to virtually patch any VLAN to each individual client. This will also pave the way for the upcoming VoIP telephony deployment in D-PHYS. The migration will be a step-by-step process and we will visit each building and floor individually to address potential questions during the migration. The typical desktop or laptop computer will not notice the change except for a short interruption of < 1 min. Certain macOS clients will need a bit of persuasion however, the required steps are described here. Things will look a bit different for new clients that connect to the D-PHYS network for the first time only after the migration: they will not display the well-known ISG D-PHYS landing page, but an OS popup or a generic ETH page. This works the same way as the ETH wifi. You either supply your n.ethz credentials in the popup or you log in via the landing page. Your machine will then be patched into the ETH docking network. If you have a specific reason to have your machine in the D-PHYS network (HPx::745 for the technically inclined), please let us know and we will register your MAC address in our database - just like you did in the past. All existing machines at D-PHYS have been preregistered for HPx::745 in order to avoid any confusion. So please be ready when Alex shows up in your group and announces the migration date.

by Christian Herzog 30 Aug '16

30 Aug '16

ISG News has posted a new item, 'Maintenance window on Monday, September 5, 17:00' In order to perform some core service upgrades, we schedule a server maintenance window on Monday, September 5, starting at 17:00 and lasting for approximately 3 hours. Most D-PHYS IT services will be affected by that downtime, including logins, file servers and e-mail services. E-mails coming in during the downtime will be held on the sender’s side and will arrive at D-PHYS with a delay. Sending e-mails won’t be possible during the window. We’ll update this posting as soon as things are back to normal.

[ISG News] Groupware upgrade
by Christian Herzog 14 Jul '16

14 Jul '16

ISG News has posted a new item, 'Groupware upgrade' On Thursday, July 21, starting at 0700 we will upgrade our groupware solution. The update is expected to take approximately one hour. As this upgrade will be a major one (version 14.3 to 16.1), you might notice a few changes. In particular: if you didn't log out before we start the upgrade, your browser might be in an inconsistent state and the new version might refuse to work. Just log out manually in this case. if you're using the ActiveSync/eSync/Exchange protocol for calendar synchronization, you will have to recreate your sync account on your (mobile) device. Just delete your existing account on the device (your groupware data will still be on our server) and add it again (see documentation). We're sorry for the inconvenience, but the synchronization code was rewritten to be faster and more stable and is not compatible to existing accounts. We have tried to identify all current ActiveSync users and will inform them via email. the web interface will get a new look (see screenshot) We have thoroughly tested the new version internally. If you find any problems after the upgrade, please get in touch. Thanks.

[ISG News] Scheduled Maintenance Downtime Starting on Thursday, 14th of April, 5pm
by Axel Beckert 07 Apr '16

07 Apr '16

ISG News has posted a new item, 'Scheduled Maintenance Downtime Starting on Thursday, 14th of April, 5pm' Due to required changes to our network infrastructure and some hardware maintenance, we're scheduling a maintenance downtime for most D-PHYS servers starting on Thursday, 14th of April 2016, at 5pm. The downtime will last several hours and single services may be down for longer than others or will be down multiple times in a row. We'll update this posting as soon as things are back to normal. Most D-PHYS services will be affected by that downtime, especially file servers and e-mail services, but also some virtual machines and most websites hosted by ISG D-PHYS are affected. (http://www.phys.ethz.ch/ and other AEM-hosted websites are not affected.) E-mails coming in during the downtime will be held on the sender's side and will arrive at D-PHYS with a delay. Sending e-mails won't be possible during the downtime either. After the migration we will benefit from a faster and more reliable network connection to our servers.

[ISG News] 2015 in review
by Christian Herzog 17 Dec '15

17 Dec '15

ISG News has posted a new item, '2015 in review' This post is meant to give you a short overview of what has been accomplished in D-PHYS IT by ISG this year. We’ve been hard at work to further improve and extend our services for you, our customers. Some highlights of 2015: new team members: both Christian Ringger and Christian Schneider joined ISG this year and have already made significant contributions to our setup. new D-PHYS website: the department website moved from the self-hosted Zope system into the ETH-wide AEM/CQ5 content management system. While the hard work of migrating all the content was done by Andreas Trabesinger, we had to sort out a lot of technical details to ensure a smooth transition and to keep D-PHYS's various web services operational. Printing: the majority of the department's printers have been migrated to the new pia printing system. We are now waiting for Informatikdienste to support student printing in order to complete the project. Storage: in 2015 the disk space occupied by data and backup grew from 685 TiB to 929 TiB, further increasing the yearly growth rate. We are also preparing to keep an off-site disaster recovery copy of D-PHYS data on tape. Outages: apart from a hardware failure of our mail server on December 2nd and a short interruption on July 2nd our system have been very stable this year. System upgrades: 2015 brought OS upgrades for almost every system: Debian Jessie on many servers, OS X 10.11 for the Macs, Ubuntu 14.04 on the Linux workstations and the first pilot installations of our new Windows 10 setup. Core services: a lot of infrastructure work has happened in the background to ensure smooth operation and seamless growth of our services in the future. Examples are: more IPv6 work, 802.1x / NAC in our network, a new network zone in the server rooms, an upgrade of our iPXE boot screen and enhanced monitoring. IT security: we participate in and support the ETH-wide IT security initiative. Happy Holidays and see you in 2016!

[ISG News] Results of IT services survey
by Christian Herzog 14 Dec '15

14 Dec '15

ISG News has posted a new item, 'Results of IT services survey' Thank you to all of you who participated in our IT services survey in late October. More than one third of you completed the questionnaire and the feedback has been extremely positive. The Department Head and ISG have evaluated the results and would like to say thanks to everybody involved. We have received many helpful comments that deserve an answer. Since the survey was anonymous, we have no way of getting back to each responder individually, so we compiled the questions, answers and comments on a nifty website that we invite you to visit: https://nic.phys.ethz.ch/it-survey/ You can browse the results, read the comments and click on the little speech bubbles to read our answers. There are a couple of topics that are sufficiently common and generic that we would like to address them here: * WiFi: yes we know it's not great, but we cannot immediately fix it as it is a service of Informatikdienste. We are working together with our colleagues of ID to resolve the problems and improve WiFi service on the campus. * many of the wishes and problems raised in your comments actually have already been solved by us. Also, * there seems to be a positive correlation between how often people contact us and their satisfaction with out services. So: Please talk to us! We can only help you if you tell us about your problem, and we hate unsolved problems. So we're going to try hard to fix them. Thanks for you attention and we're looking forward to serving you in the future.

[ISG News] New SSH Host Keys on Managed Linux Machines and partial BackupPC outage
by Claude Becker 12 Aug '15

12 Aug '15

ISG News has posted a new item, 'New SSH Host Keys on Managed Linux Machines and partial BackupPC outage' After several years it was time to update the SSH host keys of our managed Linux machines. Therefore, if you reconnect with SSH, you might get a warning similar to this one: ssh login.phys.ethz.ch @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that the RSA host key has just been changed. The fingerprint for the RSA key sent by the remote host is 36:04:d8:3d:89:a2:76:19:ef:b6:f0:0a:f2:5c:81:a3. Please contact your system administrator. Add correct host key in ~/.ssh/known_hosts to get rid of this message. Offending key in ~/.ssh/known_hosts:1 RSA host key for login.phys.ethz.ch has changed and you have requested strict checking. Host key verification failed. This is because your computer has memorized the previous host key and is bailing because the current one is different. This mechanism is designed to prevent users from man-in-the-middle attacks. In our case it can be treated as a mere notification that the SSH key has changed. In order to get rid of this warning, you simply need to delete the old key from your ~/.ssh/known_hosts file. This can be done either by deleting the entry manually or with the following command ssh-keygen -R login.phys.ethz.ch for the machine you try to ssh into. On the next SSH connection you will be prompted to accept the new key. Power users may also download the full list of SSH keys of all our managed Linux computers. On a side note, one of our BackupPC servers is currently offline because of a broken capacitor on the mainboard. Hosts connected to backuppc2.phys.ethz.ch will not be able to make backups or restore files until the broken part has been repaired.
