AC Lite. It doesn’t need controller, it’s standalone. I configure it via the mobile app.

It’s a standalone AP. No controller. Two different SSIDs.

I’ve had it running now for 2 hours and of course now it works. The only change since last time is that I’ve reset the AP and did a firmware upgrade. Perhaps that fixed it…

There’s only a single DHCP server, a Pihole, which also serves as DNS. Switch B is a cheaper switch, so that may be the culprit. I use it for heavy downloading from my Xbox and that is never a big issue. Speeds fluctuate from 100 to 900mbps (my max) but that’s not necessarily a switch problem.

Yep, thanks for checking, there’s only 1 DHCP server on my network. I’ve just moved it back to behind switch B and will do more investigation when the problem occurs again.

I’ve just moved it back to behind switch B, will do testing as you suggest.

The switch doesn’t have POE, the Unifi AP does use POE via its own POE injector.

Thanks. I’ve recently reset it, it has its own IP via DHCP. I’ve just moved it back to behind switch B, will do testing as you suggest.

I’m using Kagi and can’t be happier.

Yes, but I think it’s because of OpenVino. Some other people with Intel HD using OpenVino had similar issues. I’ve just switched to another model based on this post.

It has integrated Intel graphics, not a separate GPU.

That is good to know! Will keep an eye on memory usage of immich. I really like it, so I’m reluctant to let it go.

Thanks heaps, that’s is very useful. Will connect monitor and keyboard and have a look.

I’ve uninstalled it, it’s an index/search tool. Don’t need it :D

Thanks, it’s so awesome to see so many useful replies here! If you are interested, I found some very weird things in the logs :( https://lemmy.nz/comment/6192604

Yeah think I’ll get a standalone WiFi smart plug, not connected to my Home Assistant, as a kill switch. But you’re right, it’s overkill.

I found some weird things in the logs, this goes beyond my knowledge :( See https://lemmy.nz/comment/6192604

Yeah tracker miner sounds dodgy. I’ve only installed Immich & Frigate on the box, and no dodgy repositories. It’s also auto updating. Will do research how to check for malware, thought that was a Windows only thing :D

Thanks, but a data center is probably overkill for my needs. I’ve got it power loss protected with a UPS, and that’s more than enough for us. Thanks anyway :)

I have a RPI, but of course that one can hang too. I’ll buy a simple WiFi smart plug, standalone, as a kill switch.

Thanks! Yeah it seemed to be an OOM issue, but based on my Kagi qualities it seems like an OS issue. But, it also has an error about the GPU. Normal memory usage is more than fine, so perhaps it was a one time thing. See logs: https://lemmy.nz/comment/6192604

Thanks mate. It was a bit of a rabbit hole, I found stuff about the watchdog package, and you can configure it to use the iTCO_wdt module, but I also read it was blacklisted, and then I just gave up. I posted somewhere else in the thread what lead up to the hang. And, I think I’ll buy a WiFi smartplug so I can remotely reboot everything; assuming the WiFi still works :D

Yes, thanks for that. Good point. I checked the logs, and minutes before it crashed I can see below in the logs. Seems like either a GPU error or out of memory error. I’ve deleted tracker-miner-fs as I don’t need it. It also shows a massive list of processes with their memory usage.

Yes, thanks for that. Good point. I checked the logs, and minutes before it crashed I can see below in the logs. Seems like either a GPU error or out of memory error. No idea what tracker-miner-f is by the way. It also shows a massive list of processes with their memory usage.

This goes beyond my knowledge :(

Thanks, I’ve got a HP SFF as well. Not 100% sure how to turn it on though from Ubuntu. There’s a software based version: https://manpages.ubuntu.com/manpages/xenial/en/man8/watchdog.8.html

But I guess that’s not the one using the motherboard watchdog function.

Thanks! That should work.

Yes, very good idea. I’ve got HA on a RPI so that should be easy.

That’s interesting! I’ve converted all my docker run commands to docker compose, as I found that easier to manage. But, I guess you can’t do the dependencies like you have. Also, yours has the advantage it always pulls the latest.

Awesome, yes, definitely will do. After years of using Linux, the whole systemd thing is still a bit of a black box to me. I know how to create /start/stop services etc but that’s about it. Thanks for the prompt replies!

Yeah I used /etc/fstab which are static mounts.

I switched to autofs and that seems to be much better, as it does the mounts “at runtime”, ie when requested.

Thanks! I’ve just set that up. That would seem to solve the solution, right, without reboots?

Sorry, I’m absolutely not a Linux expert :) I use /etc/fstab for the mounts, and to manually re-mount I run “mount -a”.

Welcome in the rabbit hole of selfhosted enthousiast.

Haha yes looks like it. I only have 1 server (to be bought) and a RPI, which should be sufficient. Proxmox seems overkill for that scenario; I’ll just run Docker. Thanks.

What is the advantage of running proxmox vs install eg Ubuntu, Docker, and manage it via ssh and Portainer?

Yeah, saw them, but that’s over budget unfortunately. Thanks.

Yes, unless you vpn to home of course.

Thanks! Very helpful. Will give it some thoughts.

Thanks for the insights. I’m planning to import about 1.2Tb of photos… So RAM is most important? What about Intel gen? I’ve compared 4th and 8th gen in terms of cpu speed and 4th still scores well. Depends of course on exact cpu. 4th gen can be bought here for about a 5th of the price of an 8th…

42 yo here, same as you! I tried the game multiple times as everyone was raving about it. Got so frustrated with the bosses that I gave up.

Okay, good to know. Then I wouldn’t need an 8th gen, a 4th gen with a Coral pcie should be better I believe. Much cheaper too.

Thanks, HP it will be. When comparing Intel gens, there isn’t a massive difference between 4th and 8th gen, except the openvino detection which only works on 8th. But I can get a 4th gen for 25% of the price of a 8th gen.

Interesting re the wifi chip, as all posts I’ve found said it only works for a wifi card. Do you have a source for that?

Yeah, no wifi is no problem. It’ll be connected via cable

3470 means 3rd gen. The first number is the generation. Good to know that also works.

Thanks for your reply! So that is a 3rd gen Intel chip if I kagi’d correctly? I was planning to get a 8th gen or later. Not sure though if it’s worth it, I’m not too familiar with the differences between all generations.
