Re: Linux video camera UVC driver with multiple cameras
udev and a rule similar to this:
ENV{SUBSYSTEM}=="video4linux", ENV{ID_TYPE}=="video",
ENV{ID_SERIAL_SHORT}=="0582C6D0", SYMLINK+="video-ibm2", GROUP="video"
ENV{SUBSYSTEM}=="video4linux", ENV{ID_TYPE}=="video",
ENV{ID_SERIAL_SHORT}=="A6D77E9F", SYMLINK+="video-pr1", GROUP="video"
ENV{SUBSYSTEM}=="video4linux", ENV{ID_TYPE}=="video",
ENV{ID_SERIAL_SHORT}=="9EAC29D0", SYMLINK+="video-pr2", GROUP="video"
I don't know if that rule still works,I last used it 8 years ago. But
something similar should still work. And at least the logitech cams do
seem to have a serial number.
udevadm info /dev/video0 will dump the info. If you want to be avoid
udev, you could use the SN from the info command and create another device
in /dev with the name you want and the same major/minor number (using the
mknod command) (major/minor is in the info command). Say start at
/dev/video20 or something similar.
udev is the clean way to do it, but udev is more difficult to debug if it
does not work, and I have been burned by udev changing semantics enough to
do it the crude but easier to debug way.

Linux video camera UVC driver with multiple cameras
Hi, The Linux UVC driver for USB video cameras names devices according to the product name it gets from the USB device itself. This is fine if you have different models of camera, as each gets a different name. However, if you have, say, 3 Logitech C920 cameras, the device list in video applications shows you have many devices called "HD Pro Webcam C920", and you can't tell which is which. I looked in the driver source code to see if there is a way to tag the cameras with unique names, but there doesn't seem to be. Does anyone know if I missed something?

Re: Message during dnf update
The last Failed to write message is the only real error. The other messages are informational.The /etc/gshadow is basically trying to add the group users and it already being in the file, which is informational. The real error will be coming from one of the install scripts in one of the rpms and that is what needs to be changed (bug report on the rpm giving that error to correct the error). And you don't know exactly what rpm is doing it nor what file it is trying to write to.

Mine too, virtually all DHCP servers do (even if not providing fixed static addresses, but just nearly always giving the same addresses), that's always been the way DHCP associated clients with leases. And there are some further client ID parameters that *can* be taken into consideration. You also need to remember that some clients automatically randomise their MAC for so-called privacy (*) reasons, that can make DHCP serving a bit of a headache. * Random network addresses may anonymise you slightly, but your web- browser is going to fingerprint you very badly. > My wireless access point uses mac filtering. That I don't bother with. It can't stop cracking, they just listen and clone MACs to find one that is allowed (there are no-skill-required programs that can do that for malcontent people). It's the same false belief of hiding access point SSIDs. And it makes life difficult when you have to manually authorise everything that should be allowed to connect. Not to mention the MAC randomising shenanigans I just mentioned making it near impossible to use your own network if you use MAC filtering. It was an annoying feature my phone added in one update that took me a while to find out why its IP kept changing. -- uname -rsvp Linux 3.10.0-1160.59.1.el7.x86_64 #1 SMP Wed Feb 23 16:47:03 UTC 2022 x86_64 Boilerplate: All unexpected mail to my mailbox is automatically deleted.

Just confirming that you're referring to his email with message id: 4cd89656f28227f26e2609705bc02285164f4ce2.ca...@cwm030.com (though that may not be the ID that his system creates). If I hit reply, the whole thing got quoted, including the list footer. I notice it's not a text email: Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: base64 I wonder if that fools evolution's replying? Replying to most textual messages (plain text or HTML) does trim off signatures as expected (ones not from this list). And so far, every base64 encoded message that I've found with a signature doesn't get it trimmed of. For what it's worth, I've found almost all messages from this list to be base64 encoded (even when I can see no good reason why). I managed to find one or two that aren't, and their signatures don't get stripped off, either. In the past, when it came to list mail, and trying out various different email clients, some only regard the last "dash dash space carriage-return" signature separater on the page as the one to strip off, others picked on the first one. The clients that promote top posting (and endless stacking of messages upon reply upon reply upon reply) often don't strip signatures at all, nor have signature separators in their own postings. So, I'm just used to either selecting only the portion of an email I want to reply to, or always hand-editing the message I reply to. It's been a very long time since I found Evolution has presented a blank page when I tried to reply to someone's badly formatted message. Replying to HTML used to be a pain, you'd try to split someone's stream-of-conciousness three-pages-as-one-paragraph posting into a real paragraph, and it'd delete the whole block of text. I'd have to copy and paste into a real plain text editor, like vim, to remove all the non-textual crapola, first. -- uname -rsvp Linux 3.10.0-1160.59.1.el7.x86_64 #1 SMP Wed Feb 23 16:47:03 UTC 2022 x86_64 Boilerplate: All unexpected mail to my mailbox is automatically deleted.
