Please help me stop my baby from crying because kodi keeps buffering in c/[email protected]
[–] [email protected] 8 points 1 month ago* (last edited 1 month ago)

Installing the Jellyfin add on into kodi takes a few minutes. Nothing much to consider, just try it and see if that changes anything.

I have a similar setup (rpi with OSMC, media hosted on file server) and prefer using Jellyfin as the source for all clients, as it keeps track of watched status across everything. It's not perfect, but better than without Jellyfin.

WSL has changed the game pretty significantly, don't you agree? It's not perfect, but allows me to stay firm in my resolve never to learn powershell.

I'd spend half the money on snail amnesia research. The rest I'd just squander.

Storage box is self-serviced storage on a single server, as far as I'm aware. If you need replication, you need to rent storage at a second location and do it yourself.

By god, lemmy is civilised. 😂 I love it.

I can see what you mean, too, but am still on the liking him side I guess. And anyway, l'art pour l'art and all that, right? 😅

Hm, interesting. I didn't read it like that, but as an economist trying to make sense of what's going on and explain it to others. I didn't question whether the thoughts are original, neither do I know if there are holes in his concepts that I as a non-economist am blind to. My personal opinion, anyway, is that the message is important today (or better yet 15 years ago but nobody would have listened 😉), no matter whether he is primarily motivated by his ego or what.

Maybe this makes me part of the people he caters to, but that line of thinking doesn't lead anywhere meaningful anyway, I think.

I liked the end of the book: A call to action for us to come up with tools and technological solutions for "users" to stand together so we can create resistance against overly powerful cooperations and demand our rights. I don't think it's hypocritical for him to ask for this either. We need people to point problems out and problem solvers, both.

Have you read more of what he wrote or how did you come by that opinion on him? Technofeudalism and a number of interviews leading up to the book release was the first I was exposed to him.

Linux Distro for Jellyfin Client HTPC in c/[email protected]
[–] [email protected] 2 points 4 months ago

I have a Raspberry Pi 3 with a Hifiberry DAC running OSMC (nicely packaged Kodi on top of Debian) acting as my media center and recently installed Jellycon with the hopes of being able to use server side transcoding for a few formats my old TV doesn't support.

My verdict: Menu navigation is slow, but it's a native kodi integration (supports widgets) and playback works great once you made your way through the menus. You can selectively set transcoding options per file type which is exactly what I needed.

Best solution I've seen so far, as it also does IR remote passthrough over HDMI if your TV supports it. The addon works in any kodi setup of course. I think there might be a way to start playback from the Jellyfin web UI but haven't bothered with it. This would fully remedy the menu slowness, I think.

Is that a way of saying you think he's wrong?

I thought the book had an interesting core idea, even if his grasp on technology seems rather loose and I really disliked the literary device he used to explain said idea.

What's your take on it?

How many PostgreSQL services? in c/[email protected]
[–] [email protected] 4 points 6 months ago

Here's the docker stats of my Nextcloud containers (5 users, ~200GB data and a bunch of apps installed):

No DB wiz by a long shot, but my guess is that most of that 125MB is actual data. Other Postgres containers for smaller apps run 30-40MB. Plus the container separation makes it so much easier to stick to a good backup strategy. Wouldn't want to do it differently.

Password Manager that supports multiple databases/syncing? in c/[email protected]
[–] [email protected] 2 points 6 months ago* (last edited 6 months ago)

This is the setup I have (Nextcloud, Keepass Desktop, Keepass2android+webdav) and k2a handles file discrepancies very well. I always pick "merge" when it is informing me of a conflict on save. Have been using it like that for years without a problem.

Edit: added benefit, I have the Keepass extension installed in my Nextcloud, so as long as I can gain access to it, I have access to my passwords, no devices needed.

what's your experience with paperless? in c/[email protected]
[–] [email protected] 2 points 6 months ago

Page loading times, general stability. Everything, really.

I set it up with sqlite initially to test if it was for me, and was surprised how flaky it felt given how highly people spoke about it. I'm really glad I tried with postgres instead of just tearing it down. But my experience is highly anecdotal, of course.

[SOLVED] Firewall noob vs. port forward (discuss.tchncs.de)
submitted 7 months ago* (last edited 7 months ago) by [email protected] to c/[email protected]

Hi there, hoping to find some help with a naive networking question.

I recently bought my first firewall appliance, installed Opnsense and am going to use it with my ISP modem in bridge mode, but while I'm learning I added it to my existing LAN with a 192.168.0.0/24 address assigned to the WAN port by my current DHCP. On the firewall's LAN port I set up a 10.0.0.0/24 network and am starting to build up my services. So far so good, but there's one thing I can't get to work: I can't port forward the firewall's WAN IP to a service on the firewall's LAN network and I can't figure out why.

To illustrate, I would like laptop with IP 192.168.0.161 to be able to reach service on 10.0.0.22:8888 by requesting firewall WAN IP 192.168.0.136:8888.

Private IPs and bogons are permitted on the WAN interface and I have followed every guide I can find for the port forwarding, but the closest I have come to this working is a "connection reset" browser error.

Hope my question is clear and isn't very dumb. Thanks for the help or any explanation why I might be struggling to get this to work. Am I missing something obvious?

UPDATE The thread is all over the place, but I have made some progress:

  • RDR rule gets triggered when requesting 192.168.0.136:8888 from 192.168.0.123
  • Apache logs show 2024-02-09T17:39:17.056208857Z 192.168.0.123 - - [09/Feb/2024:17:39:17 +0000] "GET / HTTP/1.1" 200 161
  • a tcpdump (in spoiler below) on the apache container looks inconspicuous to my untrained eye, with the exception of checksum errors in some packets from the docker container (172.20.0.2). The last five lines, after the second GET request (why is there a second GET request?) appear in tcpdump after a delay of about five seconds.

**UPDATE 2**
I see the exact same behaviour with a second VM and apache directly installed on it instead of in a docker container.

***
**UPDATE 3**
Thank you everybody for coming up with ideas. And thank you most of all to [@[email protected]](https://lemmy.world/u/maxwellfire): The culprit was the `Filter rule association` in my Port Forward settings which I had as `Add associated filter rule` but needs to be `Pass`. As soon as that is set, everything works.

The full solution is a NAT Port forwarding rule with filter rule "pass", an outbound NAT rule for hairpinning, and everything related to reflection turned off in Settings > Advanced. It's that easy! 😵‍💫

Nextcloud Performance Improvements (discuss.tchncs.de)
submitted 8 months ago* (last edited 8 months ago) by [email protected] to c/[email protected]
37 comments fedilink
 

Nextcloud seems to have a bad reputation around here regarding performance. It never really bothered me, but when a comment on a post here yesterday talked about huge speed gains to be had with Postgres, I got curious and spent a few hours researching and tweaking my setup.

I thought I'd write up what I learned and maybe others can jump in with their insights to make this a good general overview.

To note, my installation initially started out with this docker compose stack from the official nextcloud docker images (as opposed to the AIO image or a source installation.) I run this behind an NGINX reverse proxy.

Sources of information

Improvements

Migrate DB to Postgres

What I did first is migrate from maridb to postgres, roughly following the blog post I linked above. I didn't do any benchmarking, but page loads felt a little faster after that (but a far cry from the "way way faster" claims I'd read.)

Here's my process

  • add postgres container to compose file like so. I named mine "postgres", added a "postgres" volume, and added it to depends_on for app and cron
  • run migration command from nextcloud app container like any other occ command. The migration process stopped with an error for a deactivated app so I completely removed it, dropped the postgres tables and started migration again and it went through. after migration, check admin settings/system to make sure Nextcloud is now using postgres. ./occ db:convert-type --password $POSTGRES_PASSWORD --all-apps pgsql $POSTGRES_USER postgres $POSTGRES_DB
  • remove old "db" container and volume and all references to it from compose file and run docker compose up -d --remove-orphans

Redis over Sockets

I followed above guide for connecting to Redis with sockets with details as stated below. This improved performance quite significantly. Very fast loads for files, calendar, etc. I haven't yet changed the postgres connection over to sockets since the article spoke about minor improvements, but I might try this next.

Hints

  • the redis configuration (host, port, password, ...) need to be set in config/config.php, as well as config/redis.config.php
  • the cron container needs to receive the same /etc/localtime and /etc/timezone volumes the app container did, as well as the volumes_from: tmp

EDIT Postgres over Sockets

I'm now connecting to Postgres over sockets as well, which gave another pretty significant speed bump. When looking at developer tools in Firefox, the dashboard now finishes loading in half the time it did before the change; just over 6s. I followed the same blog article I did for Redis.

Steps

  • in the compose file, for the db container: add volumes /etc/localtime and /etc/timezone; add user: "70:33"; add command: postgres -c unix_socket_directories='/var/run/postgresql/,/tmp/docker/'; add tmp container to volumes_from and depends_on
  • in nextcloud config.php, replace 'dbhost' => 'postgres', with 'dbhost' => '/tmp/docker/',

Outlook

What have you done to improve your instance's performance? Do you know good articles to share? I'm happy to edit this post to include any insights and make this a good source of information regarding Nextcloud performance.

Service to fetch and print email and attachments (discuss.tchncs.de)

Hi fellow self-hosting lemmings,

In an SME setting, I'm looking for a service to regularly fetch mails from an IMAP server and print incoming mails and attachments on a local network printer based on rules (e.g., only print mails where the subject contains a specific word.)

Does a solution like that exist, ideally with a browser frontend to set it up?

Thank you!
