I've been stressing out for some hours now, but I think I know what has happened, although there are still some things that's not quite adding up, and was hoping someone could help me get to the bottom of it. The actual question is at the bottom.

First some background I'm self-hosting Nextcloud on a Linode, and was notified that the public out network traffic exceeded my set threshold. I first assumed that I've had a breach on my server, but could find no trace of someone logging in. The reason I now feel at least somewhat easier is:

1. No sign of anyone ssh-ing in successfully before the time this happened from /var/logs/auth.log (I guess this is not hard to cover though...)
2. ssh through root is disabled - they would have to know my username and my password, which should not be brute-forceable, and the way it's stored in my password manager does not immediately allow linking the two (although, if my password manager is compromised I don't know what to do). I have no other signs that this has been compromised, and I think my Nextcloud-server would be a weird place to start if they had access to it all.
3. I have 2FA on my Linode account, so accessing root (which also has a different and not easily brute-forceable password) through LISH should also be difficult.
4. The amount of traffic (based on the average network traffic Linode reported) amounts to several times the total data stored on the server. I would expect a malicious actor to grab everything once, and not spend more time than necessary to needlessly duplicate the data.

What I now think happened instead is that my desktop client has resynced everything several times over. The reasons I think this:

1. The network activity started more or less when I opened my laptop this morning
2. The desktop client was for some reason entered twice in the autostart, causing two version of the client to be started at the same time. This caused some conflicts today - when I noticed this and resolved these, I quit the second instance, and that is about the time the network activity stopped
3. The same thing happened later today, which caused a spike in CPU-usage on the server, but did not trigger the same network traffic as the desktop client seems to have crashed quickly after.

The actual question However, the last piece of the puzzle that I can't figure out that still has me somewhat nervous: the maximum outbound transfer speed greatly exceeds my download speed (about 4 times). From the graph, it seems as though it maintains this high speed, but it seems to maybe just log the maximum value every five minutes, so maybe these are just spikes? The reported average over the two hours this occurred more or less matches my maximum download speed however, although I don't really think I can get that from where I am sitting on my WiFi.

Is this the glove that doesn't fit?

I'm running Jellyfin on a Debian-server in my home, and I have the associated media folders set up as samba shares so that I can transfer any new media from my laptop to the server through Dolphin (KDE file manager).

This has for the most part worked very well (except slow speeds), but I've had an issue recently where the files are not copied over properly. This resulted in glitches in for example music files that would stop playback. I checked the checksums of some of these files, and they were different from source. Seems like the glitchy files are missing some data, but at no point were I notified about this. It works fine after I removed the files and transferred again, and now the checksums match.

Is this a common issue with samba, or could it be a sign that my HDD is acting up?

I have a big presentation coming up, and this is the first time using Linux and Libreoffice for this. I've been using KDE Connect for a long time for many different use cases, but never tested the slideshow remote before now. It works as expected on KDE 6 with Wayland, except for the pointer.

The pointer will only show on my laptop screen, and not on my external monitor. This is naturally where I will show the presentation, so this is where I would want the pointer to show. This is the case regardless of which display is set to be the primary monitor. Screen are set to "Unify outputs".

I found this post explaining the exact same issue from 2020, but there was never a solution to this.

Has anyone run into the same issue and know of a way to get this working?

I am contemplating buying one of the Seagate OneTouch Hub external hard drives as a backup for my media that's currently stored on some other external hard drives connected to my home server since they are always spinning.

My local retailers don't give me many options as far as large storage storage solution goes, and the only other viable option now is a WD My BOOK 14 TB.

However, the retailer I will be buying it from goes out of its way to state that Windows or macOS is required. Is there any reason I should believe that I will run into troubles under Linux? I've had no issues whatsoever with some other Seagate hard drives (Expansion 5 TB), which I just instantly reformat to ext4 and use as normal. My guess is that this is just for the included software? I just want to make sure before I order.

(More long term I will set up a NAS, but for now time to learn and configure is more scarce than money, so I just want a solution that will prevent me from losing my data)

EDIT: For anyone coming to this later wondering the same thing, I can confirm that it works just fine. It is just the included backup software that is not compatible. I've formatted it to ext4 and currently using rsync to backup my media.

The number of containers I'm running on my server keeps increasing, and I want to make sure I'm not pushing it beyond its capabilities. I would like a simple interface accessible on my home network (that does not make any fishy connections out) that shows me CPU and RAM-usage, storage status of my hard drives, and network usage. It should be FOSS, and I want to run it as a Docker container.

Is Grafana the way to go, or are there other options I should consider?

I want to mirgrate my Nextcloud instance from a VPS to server in my home. I run the Nextcloud AIO Docker container, which uses Borg backup. The backup repo is about ~70 GB.

How would I best go about transferring it? Is using scp a good solution here (in combination with nohup so that I don't have to keep my ssh session active)? Or is there some other best practice way of doing this?

I switched to Linux about 1.5 years ago now when replacing my old Macbook Pro with a Tuxedo Infinity Book. I am super happy with the transition, and for the most part my digital life has severely improved as a result of it. There's one thing in particular though that I haven't fully grasped or understood despite all the talk about it, and that really has mostly caused confusion on my part, and that is Xorg/X11 (I don't know the difference...) vs. Wayland.

I started out with Tuxedo OS 1 and 2 running KDE Plasma 5.x.x, and thus have been on X11 for the most part since switching to Linux. I never dared switching to Wayland myself. However, they somewhat recently started offering optional upgrades to Tuxedo OS 3 running KDE Plasma 6 where Wayland is the default, and I took the plunge. The only real difference I noticed was small annoyances that I had to fix. Glitching windows running on XWayland and having to configure some .desktop-files to force apps to launch natively in Wayland. Apps not showing the correct desktop icons but the generic Wayland logo instead, making Alt+Tabbing a bit more difficult because it is harder to tell applications apart. Annoying smooth scrolling (I don't want scrolling to have as much friction as polished ice) activated in all kinds of applications that I seem to have to turn off individually. Nothing breaking (though I haven't dared booting with my Nvidia dGPU yet in fear of breaking something irreversibly...), but I haven't noticed any improvements either, and I find it a bit frustrating not knowing where to make the necessary changes and always having to search for it seemingly on a case by case basis.

Now for instance I was updating FreeTube to a new version, and the flags I previously added to the ́.desktop'-file suddenly doesn't work anymore (--enable-features=UseOzonePlatform,WaylandWindowDecorations --ozone-platform-hint=auto). The application won't launch unless I remove them, but then it launches under XWayland instead. Not that I have any issues so far running it like that, but I guess I would prefer to run everything natively in Wayland if I can.

I am currently in the process of finally getting rid of my Meta-account. In the process I have requested data extraction. The media stuff was made available pretty quickly, but the data logs are still being processed. Does anyone know what data they actually contain, and whether there's any point in waiting for it?

The reason I ask is that I also recently got a notification saying that will soon train their AI-model on my data which they will use the "legitimate interest" bullshit to do. I want to have my account deleted by the time this will be phased in (towards the end of June).

So now I am in the dilemma of waiting for the data logs to complete (which I don't know how long will take) or just delete my account in hopes that it will be purged before the AI-stuff goes into effect. I am unable to find out exactly what these data logs consists of and whether there is any point in keeping onto them for whatever reason.

Now, whether I can trust that they actually delete the data is another matter, but at least I would've done what I can, and they would break the law if the retain the data after my deletion request (under GDPR).

I have a specific issue I want to solve right now, but the topic is phrased more generally as I would love the answer to this as well. But this might be an XY-problem because of this, so here's the actual problem I want to solve:

I am using LibreWolf as my main browser, and it has WebGL disabled by default to avoid fingerprinting. I would like to keep it this way, but I am currently also making some internal tools for myself that requires WebGL (map renders with Plotly in Dash).

Is there a way to tell LibreWolf to enable WebGL only for specific sites, so that I don't have to manually toggle this when I want to look at my maps? My initial thought was that this could be solved with a site-specific about:config.

I have previously written a lot of code that is hosted on a public repo on GitHub, but it never had a license. It was written as part of my work while working for a non-commercial academic entity, and I would like to add a license before the link to the repo will be included in something that will be made public, potentially attracting one or two visitors.

This leaves me with a couple of questions:

1. Can I just add a license after the fact and it will be valid for all prior work?
2. Do I have to make sure the license is included in all branches of the repo, or does this not matter? There are for instance a couple of branches that are used to freeze the state of code at a certain time for reproducibility's sake (I know this could be solved in a better way, but that's how it is).
3. I have myself reused some of the code in my current work for a commercial entity (internal analysis work, only distributed within the organization). Should this influence the type of license I choose? I am considering a GPL-license, but should I go with (what I believe to be) a more permissive license like MIT because of this?

I've been having some issues with my network card on my new Minisforum UM690S. The issue is related to both WiFi and Bluetooth, but seeing as I have now a cabled connection for internet (and it will stay that way), I am really just in need of solving this for the Bluetooth-issue. I've been trying to figure out how to solve this using iwconfig and hciconfig, but so far I am coming up empty with a concrete solution.

The problem: The Bluetooth signal strength seems to be very poor. The computer is in a cupboard under my TV, with a wooden panel blocking the line of sight (this will need to stay closed). I use a Bluetooth keyboard with mousepad, and otherwise I connect game controllers when I want to play games. If I am close enough to the machine, especially the controllers work just fine while the keyboard is a bit wonky, but when I am in my couch (about 3 m / 10 ft away), the keyboard stops working and the game controllers are behaving mad. There will be many lines in dmesg reporting from the controller that says something like "compensating for 27 dropped IMU reports". This is a big problem for me, because the computer's main function is as an entertainment station where I will spend 99% of my time using the computer in the couch.

The keyboard has been used with no problems with a previous computer at the same distance, never had any issues with it then. I also had a similar issue with my WiFi - when the computer was temporarily placed in a room further from my WiFi hotspot, the dl/ul speeds were extremely slow. Moving the computer much closer to the hotspot fixed this issue.

I suspect the root of the issue is the low transmitting power, which for WiFi is reported to be 3 dBm (output from iwconfig). My laptop outputs 22 dBm, and the previous computer would output the same (if not 20 dBm). I don't understand the output that hciconfig inqtpl yields, but the number following "TX bytes" is significantly lower than on my laptop. I think I need to change this, but I am not entirely sure how and to what, and if it is even a good idea to mess around with this.

Some relevant (?) output: Let me know if there are other output that can be helpful in diagnosing / fixing the problem.

I am trying to set up KDE Connect between a machine running Linux Mint and my Android-device. It does not show up, and it turns out I don't receive any response if I ping it, and I have the same issue trying to ping the machine from my Android device (from Termux). I've tried two different Android devices, but no luck.

This is not an issue with two other machines I have. Both have KDE Connect setup and I can ping the phone just fine, and I can also ping from the phone. They're all connected to the same VLAN. I can also ping from this machine to the other machines. ufw is disabled.

What could be the issue here?

EDIT: Connection established suddenly after installing and running iptraf.
