The problem has been solved today, 02.01.2025 at about 10:30.

Password changes made from 27.12.2024 have to be communicated to Windows again. To do this, log on to https://registry.desy.de, select “Password” -> “Repropagate Password” in the menu, enter your current password again and confirm the input with “Repropagate Password”.

All other actions performed during the disturbance will be automatically repropagated.

-----------------

Communication between the DESY Registry (https://registry.desy.de and https://passwd.desy.de) and Windows is currently disrupted. This means that all account actions relating to Windows, e.g. password changes, account prolongations and others, do not become active for Windows.

This does not affect account changes related to all other services, e.g. Mail or Sync & Share. These will become active as usual after a short time.

As soon as the fault has been rectified, all transactions will also be carried out for Windows.

Trouble caused by: Communication problem between Windows and registry

Since Monday, 22.7.24 there have been problems with the DHCP (Dynamic Host Configuration Protocol) in the DMZ (demilitarized zone).

The following networks/vlans are affected:

Netze Vlans
131.169.4.0/24 4
131.169.5.0/24 5
131.169.6.0/24 6

Dear colleagues,
On Tuesday, 15.10.2024, maintenance work will be carried out on the Oracle infrastructures.
There are several clusters under maintenance, so it is difficult to give an exact schedule, but the work on the IT-RAC should be completed by late noon.
We will inform the users of the IT-RAC separately about the completion of the work.

In general, the DB services are available and should be accessible.
However, there will always be session interruptions as the database services have to be swivelled.

This means that for most applications that work request-orientated, such as
web servers etc., or where session pools are used, such as Apex applications, there will be hardly any impairment.

There is a residual risk of transactions being cancelled, so attention should be paid to ensuring that data has actually been saved or, even better, that access is read-only.

Affected by the maintenance work are ALL
databases/database services/database clusters.

ALL database services and thus also the applications running on them are affected!
For example:
. BPM (GO)
. DESY (EASY, dosimetry, DOOR, vehicle pool, KDS, FORMS, contract management, Zeuha and many more. - f. APEX applications see:
https://it.desy.de/dienste/uco/aktuelles/liste_apex_anwendungen_auf_desy_db/index_ger.html)
. GIS
. IAM (IAM, annual meetings, risk management)
. Registry
. DMS (document management system)
. TeamCenter

The maintenance work was communicated in September and October CUC.
We will inform you as soon as the work has been completed.
If you have any questions, please contact Oracle Service directly by e-mail (oracle.service@desy.de).

Best regards,
DESY Oracle Service

PS: The maintenance can be viewed at https://it-news.desy.de/.

As agreed in the CUC, as of Tuesday, 03.12.2024 access from extern to the Wiki service XWiki (https://xwiki.desy.de) will only be possible via VPN or SSH.
A solution for worldwide read access without login for Spaces which have to be activated explicitly for this kind of access, is currently being developed.

The reason for this measure is to increase the security level of the information provided in XWiki.

If you have any questions, please contact the IT helpdesk at any time (uco@desy.de, Tel: 5005).

The DFN-Verein will severely restrict the GEANT TCS certificate service which is offered via the service provider Sectigo. Sectigo has unilaterally terminated the service as of 10.1.2025.

This means that it will no longer be possible to issue new server and user certificates from this date at the latest. This also applies to IGTF certificates in the grid computing environment. GEANT and DFN are working on providing the service via a new provider as quickly as possible.

Time scales are not yet known here, as soon as
information is available we will let you know.

If you are using server or user certificates from the above-mentioned certificate service yourself we strongly recommend that you renew the certificates that are due to expire in the next few months now.

Information on how to deal with server and user certificates can be found at.

Reason:
Misbehaviour of the software if https://chat.desy.de is not used.

Access to commercial channels and software repositories of Anaconda Inc. has been blocked DESY-wide with immediate effect.

Anaconda Inc. meanwhile considers research institutions like DESY as commercial users, for which corresponding usage fees apply. To prevent accidental use of non-free services it has been decided to block access to the Anaconda Inc. repositories (repo.anaconda.com) from the DESY network with immediate effect.

Existing conda environments and the Windows DSM installations will not be affected. Access to conda-forge and all other free channels hosted on anaconda.org will still be possible. Only the access to the non-free anaconda channels and download of the Anaconda Inc. provided installers (anaconda, miniconda) will not be possible anymore. We recommend to use miniforge (https://github.com/conda-forge/miniforge) instead.

Please get in touch with UCO (uco@desy.de) in the very unlikely case of problems due to the blocking of the commercial anaconda channels.

Ubuntu 24.04 LTS is now available for installation on server and desktop systems.

The general release notes for Ubuntu 24.04 can be found under: https://discourse.ubuntu.com/t/ubuntu-24-04-lts-noble-numbat-release-notes/39890
Important information on changes that could affect admins in particular are documented here: https://confluence.desy.de/display/linux/Ubuntu+24.04+changes

Ubuntu 24.04 for server installations is in production status and the version of Ubuntu to choose.

Furthermore, Ubuntu 24.04 is also available as a green desktop.

There are some notes on this:
1. Ubuntu 24.04 is the recommended installation version.
Due to the few installations of Ubuntu 24.04 on desktops currently, the present status is "early production".
On request, we will install 22.04 systems until 01.01.2025. After this date, new 22.04 installations on desktops are subject to individual decisions.

2. Existing 22.04 green desktops receive support and updates until April 2027.
Existing 20.04 green desktops receive support and updates until April 2025.
(Support for new hardware or software might be limited though, in case of problems a migration might be recommended)

3. When you want to upgrade a green desktop from 22.04 or 20.04, a new installation is required.
Since Ubuntu 20.04 it is possible to keep the home partition, but this feature is only used occasionally.
Unexpected states on some systems could create issues, so please backup your data as a precaution.
Please note in the request if you want to use this function with the new installation.

More information about the green desktop can be found at: https://confluence.desy.de/display/linux/Green+Desktop+FAQ

The end of life for Ubuntu 20.04 will be in April 2025.
Please plan to migrate from Ubuntu 20.04 to Ubuntu 24.04 or another supported distribution during the lifetime of Ubuntu 20.04.

If you have any questions, please contact unix@desy.de.

On Wednesday, 31.07.2024 at 9:00 a.m. the central Linux system pal-el7.desy.de will be shut down.
Users should use the alias pal.desy.de instead of pal-el7.desy.de.

The operating system on pal-el7.desy.de is end-of-life and will therefore no longer receive updates.

On Wednesday, 17.07.2024, the old eduroam login service will be switched off. From this date, only login with the Easyroam app, which has been in use for several years, will work. All other devices that do not use the app will no longer be able to connect to the eduroam WLAN.

All users who are still using the old login service will be notified by e-mail.

Since 10.07.2024, 10:00 a.m. the websites https://bitbucket.desy.de and https://stash.desy.de are no longer accessible as planned.

The servers will be shut down completely in about two weeks.
