HPC: Problems with the workspace file system - HoreKa, HAICORE, FTP affected - FIXED

Last weekend (19.7./20.7.) a serious SharePoint security vulnerability was made public, which has already been actively exploited in installations of other organizations worldwide.

The security measures proposed and required by Microsoft were activated on the SCC servers thanks to systems being kept up to date.

In the night from Sunday, July 20, to Monday, July 21, Microsoft released patches and further details to fix this vulnerability, which were immediately implemented by us on Monday morning.

AFFECTED / IMPACT
Service: JupyterHub for teaching (pilot)

Service News: https://stage.scc.kit.edu/en/aboutus/18424.php

Dear colleagues at SCC,
as already announced, Print & Plot is changing the procedure for issuing A3/A4 single-sheet print jobs for SCC employees from today, 1.07.2025. From today, you will find your printouts in the output tray for KIT employees directly next to the Print & Plot information counter.
IMPORTANT: We would like to point out once again that from now on your printouts will be available in the public output area and could therefore be viewed or even stolen by unauthorized persons. Therefore, please use the “print2me” function of the floor printers for data-sensitive printouts in future.
Please also note that from now on your print jobs will only be kept for a maximum of three calendar weeks. The deadline is Friday, around 18:00, when we change the color of the cover sheets of the print jobs. The respective change of week is accompanied by a re-sorting of the printouts. The printouts move from the “current week” area (white labels) to the “last week” area (yellow labels) and in the third calendar week to the “penultimate week” area (red labels) - all on the same output shelf. At the end of the third week, the print jobs are stored in a collection box with little(!) conservation until the following Wednesday before they are disposed of.

DESCRIPTION
The classic team will no longer be available from July 1, 2025.

AFFECTED/IMPACT
Users who are still using Teams Classic must migrate to the new Teams interface to be able to continue using the MS Teams desktop app.
Alternatively, the MS Teams WebApp can be used via a compatible browser (Google Chrome, MS Edge) via https://teams.microsoft.com .

PLEASE NOTE

UPDATE, 07.01.25
In 2024, some components could be replaced, but there are still components in use where the malfunction could occur.
_ _ _

A misbehavior has been detected between a network switch type used at KIT South Campus and a Windows 11 update (version 22H2). Due to this misbehavior, the network port on the switch is automatically switched off.
As a result, the network connection or network access for the connected device is no longer available.
To enable network access, the data socket used must be communicated to the IT representative / IT admin of the OU so that he can apply for enabling via the SCC network team.

WORKAROUND
To prevent the network port from being switched off, the LLDP service can be disabled under Windows. This can be done manually (computer-specific) under "Network adapter properties". Furthermore, the SCC provides the group policy "SCC-FMC-LLDP_disable", which can be linked to the computer accounts and automatically disables LLDP under Windows. Unlocking of already blocked ports can be requested from the network team via the IT representative/IT admin of the OU.

AFFECTED
Windows 11 Nutzer mit Updatestand 22H2 (und voraussichtlich höher) in Verbindung mit spezifischem Netzwerk-Switchtyp

TECHNICAL DETAILS
As of Windows 11 update level 22H2, sending Link Layer Discovery Protocol (LLDP for short) packets on a specific type of switching causes a network loop detection service to trigger on the switch, automatically blocking the network port.
