  • @cyclohexane I can only speak from my personal experience having hosted both XMPP and Matrix for friends/family before.

    Ran XMPP (eJabberd) for round about 10 years and it never really was a trivial process, neither for me as admin nor for my friends/family with regards to parcipating.
    Basically, back then, I had to manually extend eJabberd with a bunch of XEPs (namely push notifications, message carbons and message archive) to increase the useability and user convenience to even stand a chance getting people on board and able to use the system. The client ecosystem was not quite there yet either - Conversations for instance had just come around to shaping up for android, Gajim for cross-platform was pretty fine though.
    Let’s not talk about E2E encryption either: GPG - not a chance, OMEMO was just coming around as well and was not yet very reliable.

    Matrix on the other hand was quite the breakthrough for me as an admin with regards to user acceptance. I do believe that a big part of that comes from the concerted effort to have a unified client (Element) available on any platform - web, fat clilent, mobile client.
    By now there’s also a ton of cross chat platform bridges which also greatly serves as a “selling point” towards users. And most imporantly, again in my humble opinion, the required technical knowledge barrier for users is just not comparable to XMPP.

    Don’t get me wrong, I’ve learned so much as an admin setting up and hosting XMPP and for a short while I even had a PoC going at work to try and advocate the protocol, but in the end Matrix feels like a worthy successor to me.
    It allows me to convince “normal users” to use a federated, self-hosted and free chat platform reliably - and that’s what mostly matters to me :wink:



  • @Templa Online play might be out of the question toninght. Their server’s are getting hammered as we speak - thankfully there’s always full offline mode now, but I can see how people would hesitate on using that.
    Just a matter of patience I guess :wink:
    I am, however, quite impressed with the good customer relations coming from the developer. They’re pretty transparent with status updates on the login issues right now. I can respect that alot.








  • Ironically, if I would have had more services running in docker I might not have experienced such a fundamental outage. Since docker services usually tend to spin up their exclusive database engine you kind of “roll the dice” as far as data corruption goes with each docker service individually. Thing is, I don’t really believe in bleeding CPU computation cycles by running redundant database services. And since many of my services are already very long-serving they’ve been set up from source and all funneled towards a single, central and busy database server - thus, if that one experiences sudden outage (for instance power failure) all kinds of corruption and despair can arise. ;-)

    Guess I should really look into a small UPS and automated shutdown. On top of better backup management of course! Always the backups.



  • Excellent choice. I’m running a physical Routerboard and a virtual RouterOS inside my hypervisor for redundancy.
    The license for virtual RouterOS is dirt cheap and has more features than you could ever dream of with any of the the big network device manufacturers.
    The physical devices are very well designed for their relatively modest price and likewise fully featured. Perfect for any home lab or to play around with IEEE conform protocols.





  • I don’t see a clear indication that you have too low RAM… RAM should be “used” fully at all times and your “cached” RAM value suggest you still have quite a bunch of RAM that could potentially be consumed by applications when they need it.
    I cannot clearly see a swap usage in the graphs - that would be an interesting value to judge the overall stability of the system with regards to fluctuating RAM usage.

    However, once you notice the problem again, right after you manage to log in, run a “dmesg -T | grep -i oom” and see if any processes get killed due to temporarily spiking RAM consumption. If you’re lucky that command might lend some insight even now still.

    Also, what if you run a “top” command for a while, what’s the value for “wa” in the second line like? “wa” stands for I/O wait and if that value is anything above 5 it might indicate that your CPU is being bottlenecked by for instance hard disk speed.






  • I would not upgrade the contract, even if you go beyond your 50mbit UPLOAD speed you won’t be sure that no buffering and hence drop in streaming will happen. Note you have a “500Mb Broadband” contract but the upload is limited to 50Mb. Asymmetric bandwidth is typical for “consumer” internet you mostly consume/download - contrary to “hosting” internet uplinks which typically are symmetric and very pricey since you are typically hosting/uploading.

    You need specialised software to make sure you can transmit big, uncompressed real-time data (which video basically is) over the internet. It’s basically what Youtube does for its users.
    It hosts arbitrary uncompressed video data you upload to it (this is your NAS - which you have now) and then displays that data to users on the web in a compressed, streaming fashion (this is what streaming software would handle - which you do not have yet).

    In your scenario issues will arise, naturally.
