PSA, Logitech has removed Hardware H.264 Encoder from some WebCams
Recently got a Logitech C920 at work for working remotely, with Linux. When attempting to set up a remote streaming solution, i shocked to find that the newer ones no longer have hardware H.264 encoder.
This is the official Logitech wbepage declaring the removal of this feature from C920, C922 and BRIO models: [SAY GOODBYE TO IN-CAMERA HARDWARE ENCODING](https://www.logitech.com/en-us/video-collaboration/resources/think-tank/articles/article-logitech-and-h264-encoding.html)
For comparison, below are the output from my "v4l2-ctl", which shows the camera having only 2 pixel formats: **RAW** (YCbCr 4:2:2) and **MJPEG**
$ v4l2-ctl --info --list-formats

With various pages, you see instructions about specifying the pixel format to be "h264" for taking advantage of its HW encoder for streaming. Those instructions would not work with the newer versions of this WebCam.

​
**TL;DR**, if you're looking for a WebCam with HW video encoder, the once-popular-model Logitech C920 (and C922) would no longer be an option. (especially important for Raspberry Pis, routers, or whatever system with limited resources for libx264)

New Linux Distribution: Clear Linux by Intel
Hi there, I'm amazed!
I came across a new Linux Distribution developed entirely by Intel and Intel claims it can surpass in performance any Windows OS and any Linux Distribution nowadays.
With its software specially optimized for running in Intel hardware, even if it is very old Hardware (some web sites claim it works even better with AMD Ryzen CPU's) it's a must to any distro-tester out there to try.
It also has a brand new "package manager" to install software called "SWUPD", instead of "yum", "apt" or "dnf". And I say "package manager" in quotes because Intel says it does not install packages but bundles; saying that bundles is a better way to install software with all their dependecies included instead of installing and checking for separate dependecies in every installation (something like flatpak).
I give you the official webpage of the distribution:
[https://clearlinux.org/](https://clearlinux.org/)
And some information about SWUPD:

Converting Telnet to SSH
Hi
I have a console server that only supports telnet. So if I want to connect to 3 devices console port I telnet to my console server on [10.0.0.10](https://10.0.0.10) port 2001-2003
How do I setup a SSH server that will automatically connects my SSH session to a telnet session?
I want to be able to SSH to SSHPROXY:2001, login and get the telnet of [10.0.0.10:2001](https://10.0.0.10:2001).
I have looked all over the internet but cannot find a good solution for this.

Do you have any SATA disks? I'm asking 10 seconds of your time to help with fwupd/LVFS
I'm trying to make updating ATA drives a bit safer and want to lock the firmware to a specific vendor. I've got a big (possibly incomplete) table-of-data with some globs that detect the vendor for each model string. There's nothing in the ATA spec for the vendors to use and so it's all quite inconsistent, hence the fuzzy matching.
Can you add a reply to this post with the output of `cat /sys/class/block/sd*/device/model` please. It's completely safe to run and no device access is done. Thanks in advance!
There is more information here for the curious: [https://blogs.gnome.org/hughsie/2019/12/11/improving-the-security-model-of-the-lvfs/](https://blogs.gnome.org/hughsie/2019/12/11/improving-the-security-model-of-the-lvfs/) \-- comments and questions welcome.
