    Legal concerns with self-hosting
  • It barely works on my old version of lemmy, probably fixed now then. It would be nice if there was a was to turn that off and only use pictrs only for locally uploaded images. Since I'm the only person here caching isn't too important.
    I wonder if I could shut pictrs down and only use an external image hosting for images?

  • Lemmy sometimes caches remote content in pict-rs. It's a bit broken so you usually don't see it, but it does do it occasional

  • Related, What about a personal instance only I use? I can choose what communities I want but I can't control what is posted on those communities. Someone could post something illegal to a beehaw community (and have) and the mods remove it, but does the deletion of images and posts federate? In know matrix keeps copies of every deleted file in a room on all homeservers, what about lemmy?

    Help understanding the peertube P2P system
  • I have done some testing and I found a few reasons I'm having issues with webtorrent:

    • The only reason they where working at all is because they were downloading from the HTTP URL in the torrent file, P2P was not working at all.

    • To download the webtorrent from the blender instance I need to have the video watched in my browser to peer with the webtorrent client, the instance peers don't work on non-peertube webtorrent clients.

    • The reason instant.io was broken is my adblocker was blocking the tracker.

    • The tracker in my peertube instance is broken.

    EDIT:
    I was a bit wrong here, there are two different formats in peertube: webtorrent and HLS. I was getting confused why the video on my instance (HLS) and the one on the blender one (webtorrent) was behaving differently with webtorrent clients. They are completely different formats so that makes sense now.

    Help understanding the peertube P2P system
  • Webtorrent seems to have some issues with peer discovery. I've tried the instant.io site they have linked on webtorrent.io and I can't get it to download or share anything, the desktop client managed to download a torrent from my peertube instance over normal BitTorrent but I can't share it over webtorrent. I downloaded a video from my peertube instance using btorrent.xyz over webtorrent but I can't seed new files because the peers don't find each other. when I use a webtorrent with a tracker (like peertube) it works fine but how were sites like instant.io supposed to discover peers without trackers? I don't think DHT exists for webtorrent yet.

    You can manually seed videos on instances using redundancy but I was thinking automatic redundancy for watched videos might be a good idea, I guess you can do automatic redundancy for entire instances but that would take up a lot of storage space.

    One of the nice thing with BitTorrent is the high reliability so I assumed that was what peertube was trying to do, I guess the idea is not to provide data redundancy but to split load instead?

  • why? if 5 instances are seeding the video, clients should be able to download from all 5 instances and spread the bandwidth usage right?

    Help understanding the peertube P2P system
  • Would it not make more sense if your instance downloaded and redistributed the torrent? then you could keep seeding after the tab closed. it also wouldn't leak your IP then.
    What about peer discovery? I opened that webtorrent website in two browsers and they didn't peer, is that demo real?

  • Can someone help me with how peertube P2P works? I can understand how ActivityPub is used for all the "social" parts but I'm a bit confused about the actual video player.

    Redundancy: I have my own instance and I made a redundancy of a video from the blender instance. if I watch the video on my instance I see 2 peers, my instance and the blender one. I can seen both in Firefox dev tools. If I watch the same video on the blender instance I see 7 peers, the blender instance, mine, and others. why are these extra peers not showing on my instance? do I need to do something? If I watch the video on one of these other instances mine does show up in the their peers list.

    I also made a video from framatube redundant but my instance doesn't appear as a peer on framatube.

    Client P2P: If I watch a video does my browser share It over P2P? if so what is the point of this? it seems to lose the video as soon as I leave the page so this functionality seems a bit useless to me.

    EDIT: Answered in comments.

    BitTorrent: If I download a video I get the option of a BitTorrent torrent. If I seed this torrent can it be leeched by web clients? I tried and It doesn't show up in the peer list. What's the point of running a full BitTorrent tracker if it doesn't work with the main P2P system?

    EDIT: BitTorrent is incompatible with webtorrent that peertube uses. Peertube also uses HLS instead of webtorrent and behaves a bit different (you can't seed it with a webtorrent client).

    Peer discovery: As I said in 1 and 2 how does the player actually find peers? Is there something like DHT or a tracker built in to peertube? if it's an internal tracker how does the tracker find peers?

    EDIT: It uses a tracker build in to peertube.

    Thanks for any help.

    Since they have come back in stock, I bought a Pi 4 2GB and a Pi 4 4GB. the 2GB model had 2 bent GPIO pins and rattled when shaken, so I opened an RMA request for it. the 4GB model has arrived, and it has small solder blobs on the back of the board (see images)

    !

    ! Is this normal or have I just got unlucky with both Pis? I managed to scrape off solder on the first image but they have left a mark on the board. The 2GB model seems to be completely working and the 4GB one boots to the bootloader but I'm out of SD cards to test it any further. Should I also RMA the 4GB model or am I being silly here? Thanks.

  • Who needs all this crazy firewall stuff when I have my

    And for IPv6 you don't need a firewall, just use slaac and hope no one finds the address /s

  • [Reposting] Server recommendation

    Oops! I just nuked my lemmy instance and the other post wasn't in by backups, sorry about that! please don't reply to the other post because I can't see it

    Reposted: Hello, I’m looking for a good first server for a homelab. I do already have an old Dell poweredge 1950 I got for £30 but it’s:

    Loud Draws 350W Costs too much to run Only has 2 HDD slots DRAC card needs Internet explorer

    I’m not too bothered by the noise because I can just move it, but the electricity cost is quite ridiculous for something less powerful than my PC in every way. I live in the UK so electricity prices are a huge factor for this.

    My Ideal specs are:

    ~16 cores (total) >= 128GB RAM ~100W idle power draw >= 4 3.5" HDD bays Preferably HBA mode on RAID card £100-200 2U

    Is this completely unreasonable? I have found servers that match this all except the 3.5" bays and 2U. Initially I found a Dell server with 128GB of RAM and two 12 core CPUs for about £200 but I realised it only has 2.5" bays. There is a nice R720 on ebay I am watching but it will probably skyrocket near the end of the bid. Also, it probably draws a lot of power. Any suggestions? do I just need to raise my price? Thanks

    Here is my attempt to archive r/homelab before it went dark. Google says there about 92,400 results for site:reddit.com/r/homelab, I have 2098, that's only about 2% of it. Maybe there is something of use to you in that 2%.

    Please don't webscrape, if you want all the data you can get the raw BDFR archive at https://archive.douwes.co.uk/reddit/homelab.tar or the live web version at https://archive.douwes.co.uk/reddit/homelab-web.tar

    I made a flag waver bot for this community. call it with !wave in the comments or post body.

    EDIT: there seems to be a bug in the bot library i'm using and it will reply anywhere on lemmy as long as I am subscribed to the community. I may shut the bot down until this is fixed to prevent spam.

    EDIT2: It should be working now, I added a workaround for the library bug and opened a github issue.

    Update: I have added body text waving and waving of multiple links in a post. Also waving links in comments. Example (see comments): test image another link

    Update 2: It's open source now!! github

    Update3: lemmy.world is not federating with my instance for some reason, I can make comments but none of your comments are reaching my instance and the bot is not responding.

    I've run some tests and the issue here is lemmy.world, I can see a post I made to !vexillologyjerk@lemmy.antemeridiem.xyz but not !vexillology@lemmy.world the issue seems to be intermittent starting and stopping throughout the day, needless to say there isn't anything I can do about this, sorry. It might be because I'm still on 0.17.4 but my server won't run 0.18.0 and the bot won't run on that version. nvm lemmy.world is also on 0.17.4, I have not idea what this issue is

    I don't know if renting a dedicated server goes against the point of selfhosting but whatever. Everyone seems to recommend hetzner on reddit because they are cheaper, but OVH seems to be much cheaper that hetzner for low end servers, especially the Kimsufi and So You Start ranges.

    This is the server I was looking at with OVH: CPU : Intel Xeon D1520 - 4c/8t - 2.2 GHz/2.6 GHz Memory : 32 GB DDR4 ECC Storage : 4 x 2 TB HDD SATA Soft RAID Public bandwidth : 250 Mbps Price: £26.66 per month.

    hetzner seems to start a lot higher with specs, but I don't need 64GB of ram and a 1Gb/s internet connection, The instance I am posting this from is the lowest spec kimsufi possible with an intel atom and 4GB of RAM and that is running lemmy and mastodon fine.

    Is there something else bad about OVH that I am missing? (other than the flammable servers)
