Hello everyone,

Just wanted to share this story, because it took me some time and hopefully this can save some time for you all…

UPDATE ! 2022-10-18 (New unifi controller version / Ubuntu version)

There was a day I was working on my unifi controller and wanted to make it safer by adding an SSL certificate.

Piece of cake I thought, but while doing this the ’trial and error’ way of it-life, I combined all the google search and community pieces together..

I now run Unifi Controller 7.2.94 on Ubuntu 22.04.1 LTS and I have a Comodo/Sectigo wildcard *.domain.tld certificate.

Important note, I can download my Versio certificate from my provider decrypted or encrypted.

I now used the decrypted versions.

Work around this issue you need to add the following registry value in WinPE:

reg.exe add "HKLM\Software\Microsoft\Internet Explorer\Main" /t REG_DWORD /v JscriptReplacement /d 0 /f

To enable this change in MDT, we recommend that you back up the following file: C:\Program Files\Microsoft Deployment Toolkit\Templates\Unattend_PE_x64.xml and to modify it as follows:

Zonder enige twijfel de voornaamste update bij vSphere 8 is de ondersteuning voor DPU’s, oftewel Data Processing Units. Deze toevoeging komt uiteraard niet onverwachts. Zoals gebruikelijk bij VMware was ook dit eerst een project, namelijk Project Monterey.

De impact van de toevoeging van de ondersteuning voor DPU’s aan vSphere is vrijwel niet te onderschatten, zeker niet op de langere termijn. Deze programmeerbare chips spelen namelijk een steeds belangrijkere rol in datacenters. Ze moeten er zorgen voor stevige prestatie- en efficiëntiewinsten voor omgevingen. Je kunt namelijk specifieke netwerk- en securityfuncties van CPU’s offloaden naar DPU’s. Standaard ben je daar tot wel zo’n 20 procent aan resources binnen een CPU aan kwijt. Die capaciteit komt met de inzet van DPU’s dus beschikbaar voor workloads. Volgens VMware kunnen applicaties die sterk afhankelijk zijn van een hoge bandbreedte en snelle toegang tot cache (denk aan in-memory databases) rekenen op 20 procent besparing voor de CPU-cores en een 36 procent hogere transactiesnelheid. Dit zonder concessies te doen op het gebied van prestaties. Onderaan de streep moet het geheel op deze manier een lagere TCO opleveren.

To disable fingerprint authentication when the laptop lid is closed, and re-enable when it is reopened, we will use acpid to bind to the button/lid.* event to a custom script that will stop and mask the fprintd service on lid close, and unmask and start the fprintd service on lid open.

We also check that the HDMI cable is connected by testing the contents of /sys/class/drm/card0-HDMI-A-1/status.

Follow the steps below:

1. Create file /etc/acpi/laptop-lid.sh with the following contents: #!/bin/bash lock=$HOME/fprint-disabled if grep -Fq closed /proc/acpi/button/lid/LID0/state && grep -Fxq connected /sys/class/drm/card0-HDMI-A-1/status then touch "$lock" systemctl stop fprintd systemctl mask fprintd elif [ -f "$lock" ] then systemctl unmask fprintd systemctl start fprintd rm "$lock" fi
2. Make the file executable with chmod +x /etc/acpi/laptop-lid.sh
3. Create file /etc/acpi/events/laptop-lid with the following contents: event=button/lid.* action=/etc/acpi/laptop-lid.sh
4. Restart the acpid service with: sudo service acpid restart

Now the fingerprint will be used only when the lid is open.

In order to restore the correct state of the fprintd service if you disconnect/reconnect while the laptop is off, you may call the above script from a systemd init file. The steps to do this are the following:

1. Create a file named /etc/systemd/system/laptop-lid.service with the following contents: [Unit] Description=Laptop Lid After=suspend.target [Service] ExecStart=/etc/acpi/laptop-lid.sh [Install] WantedBy=multi-user.target WantedBy=suspend.target
2. Reload the systemd config files with sudo systemctl daemon-reload
3. Start the service with sudo systemctl start laptop-lid.service
4. Enable the service so that it starts automatically on boot sudo systemctl enable laptop-lid.service

Now the status should be correct even after connecting/disconnecting when the computer is off.

Linux Kernel 6.0 Officially Released

Linux 6.0 kickstarts the 6.x series in fine form, bringing an assortment of performance improvements, new hardware support, security fixes, and the usual grab-bag of file-system tweaks to the fore.

Announcing the release over on the Linux Kernel Mailing List, Linus Torvalds said: “As is hopefully clear to everybody, the major version number change is more about me running out of fingers and toes than it is about any big fundamental changes.”

“But of course there’s a lot of various changes in 6.0 – we’ve got over 15k non-merge commits in there in total, after all, and as such 6.0 is one of the bigger releases at least in numbers of commits in a while.

For a pinch more detail on what’s new in Linux kernel 6.0, read on.
