Most hubs didn’t protect you from anything in particular.

Most of them would forward everything to every port, some really insane ones would strip out the spanning tree that could have prevented a loop.

It’s been a long time since I did anything that goes as far into a network as the desktop, but 15+ years ago we had a customer ring up with the same sort of complaint. After we followed the breadcrumbs on site we found a little 8 port hub ( that we hadn’t supplied ) plugged into two wall ports that went to two different Cisco edge switches in the server room, two cisco phones also with their passthrough ports both patched into same switch and then two desktop PC’s.

Amazing.

I replaced mythtv with tvheadend on the backend and kodi on the frontend like 5 or 6 years ago.

The setup and configuration at the time on mythtv was slanted towards old ( obsolete ) analog tuners and static setup and tvheadend was like a breath of fresh air in comparison where you could point it at a DVB mux or two and it would mostly do what you want without having to fight it.

I’m not sure how much longer I’ll want something that can tune DVB-S2 and DVB-T though. Jellyfin and friends handle everything other than legacy TV better than kodi these days.

I don’t have a good answer for you.

DHCPv6 is pretty well the only good way to have a prefix delegated by your ISP and have it chopped up and deployed in an automated fashion through multiple layers of an edge network. I’m also a real fan of the audit trail in the logs that results from a stateful transaction.

Some background info if you haven’t run into it though is described by this google issue tracker id: https://issuetracker.google.com/issues/36949085. The summary is that one guy at google is obstructing DHCPv6 being implemented on android.

I’ve built out a bunch of IPv6 networks that implement DHCPv6 on the edge. I personally use a whole lot of android devices and none of them get IPv6 addresses, pretty well everything else does. I’m mostly cool with it at this point, eventually the guy who is obstructing IPv6 at google will move on.

The most impressed I’ve been with hardware encoding and decoding is with the built in graphics on my little NUC.

I’m using a NUC10i5FNH which was only barely able to transcode one vaguely decent bitrate stream in software. It looked like passing the hardware transcoding through to a VM was too messy for me so I decided to reinstall linux straight on the hardware.

The hardware encoding and decoding performance was absolutely amazing. I must have opened up about 20 jellyfin windows that were transcoding before I gave up trying and called it good enough. I only really need about 4 maximum.

The graphics on the 10th generation NUC’s is the same sort of thing that is on the 9th gen and 10th gen desktop cpu’s, so if you have and intel cpu with onboard graphics give it a try.

It’s way less trouble than the last time I built a similar setup with NVidia. I haven’t tried a Radeon card yet, but the jellyfin docs are a bit more negative about AMD.

I swear allegiance to the only one true storage vendor, Micropolis. The Micropolis 1323A being the embodiment of perfection in storage basked in the glow of the only holy storage interconnect, MFM.

I wait patiently for the return of Micropolis so that I may serve as their humble servant.

Oh not seriously, just making fun of the LTT vote which resulted in Linus using one for a bit.

A fairphone actually sounds pretty cool.

What you need is an LG Wing: https://en.wikipedia.org/wiki/LG_Wing

Your bridge isn’t bridging properly. If Router B is sending a destination unreachable then the packets are being handled on it further up the stack at layer 3 by some sort of routing component rather than by a layer 2 bridging one.

Often on Linux group membership changes only take effect on login. So you could try logging out of your session and logging back in after your group changes to test that theory out.
