I’d seen Mindustry before on Steam … it looked interesting, but never “interesting enough”. I decided to pick it up given all the love it’s getting here :)

1·8 months agoNot sure what you’re using to generate that list/formatting is a bit difficult.
I don’t have a cluster since it’s effectively single user + @[email protected] (in theory a few other people have access, but they’re not active), single machine, it’s just more or less the out of the box docker stuff on a bare metal machine in my basement + a digital ocean droplet.
The droplet is what I’m using to have a static IP to prevent dynamic DNS nonsense + it provides some level of protection against a naive DDoS attack on random fediverse servers (since I can in the worst case, get on my phone and severe the ZeroTier connection that’s using to connect the droplet to my basement server).
I’m pretty confident whatever is going on is payload related at this point.

So, I think this is a (helpful) general comment but wrong in this/my specific case.
The server is so small it’s not really going to register on a 10-minute frequency for outgoing content – I’m not that much of a lemmy addict! haha.
You can see in a comment here my most recent comment to lemmy.world did sync: https://lemmy.world/comment/8728858
I’m not having any issues with outgoing content, beehaw, the KDE instance, and several others. It’s just lemmy.world that’s acting up (which is unfortunately because it’s my favorite – I mod/run several communities and donate to here/them – haha).
Yeah, I mean things should be fine in general; like I said this has been working for quite a long time now without issue.
The machine that’s actually doing the work here is quite powerful and is used to run several game servers in addition to Lemmy … Lemmy really isn’t much more than footnote in resource usage:

So, I think you’re most on the right track of the responses…
It seems to just be exclusively incoming from lemmy.world. If you look here, my most recent comment is on lemmy.world:
https://social.packetloss.gg/comment/1415801 https://lemmy.world/comment/8710941
The instance just isn’t getting any new posts, comments, or votes back from lemmy.world.
Everytime I shut down the lemmy server I see this:
2024-03-23T17:34:33.774333Z WARN lemmy_server: Received ctrl-c, shutting down gracefully... 2024-03-23T17:34:33.774912Z WARN lemmy_federate: Waiting for 1618 workers (30.00s max)That number never seems to move, there are always 1618 works. I’m not sure if that means anything or not regarding pending processing or what have you.
I am seeing in my publicly facing nginx logs:

I’m not sure what to do about that though.
This server is not resource starved:
load average: 0.04, 0.09, 0.10 total used free shared buff/cache available Mem: 31507 7651 1092 164 22764 23239 Swap: 16087 1 16086It’s just this lemmy.world data that’s suddenly out of wack after months of normal operation (both on lemmy 18 and 19).
It feels like a bad payload that the server just can’t move past for some reason and lemmy.world keeps sending.
I had logging on the lemmy container itself piped to /dev/null because it’s just such a noisy log. I turned it back on… I’ll see if I can find more information next time lemmy.world posts.
Yeah I’m basically the only user of this server. Good data point that you’re not having issues though.
It’s been up on 19.x for a few months now. It’s also a full on bare metal server with a ton of resources, it’s not at all starved.
It’s almost like someone posted something to somewhere that “jammed” Lemmy and it just won’t get past it but I’m not sure how to figure out what that would be or how to unjam things.

(But Dark, that’s WebM not WebP! – they share the same license: https://groups.google.com/a/webmproject.org/g/webp-discuss/c/W4_j7Tlofv8)
I mean… if you’re running millions of sites on one box, and that itself isn’t an issue, I’d assume your port saturation/traffic is pretty low.
I don’t know anything about Netbird, but I’ll link you to my ZeroTier pitch the last time I noticed someone talking about Tailscale: https://lemmy.world/comment/1058287.
13·1 year agoFrom what I’m gathering, they have very different pronunciations in British English as well. I’m not sure about this shower thought, it seems like OP might be the one that’s mistaken?
That only stands true when the issue is not being actively exploited.
If you send these files over SSH, you’re good as that’s encrypted by ZeroTier and then encrypted again inside the SSH connection (and SSH does have perfect forward security).
See their cryptography section of their docs for more info.
You can read more here about what they’re working on:
- https://www.zerotier.com/blog/research-notes-on-2-x-cryptography/
- https://www.zerotier.com/blog/research-notes-aes-gmac-ctr-siv/
It’s been to long since I’ve read that to give anything more than a condensed “they’re improving their crypto significantly with ZeroTier 2” (not to mention memory safety via Rust).
I think it’s pretty secure and it will be getting better soon. In reality, I think it’s much more secure than what most people will end up with otherwise.
ZeroTier is open source, long running without incident, and the traffic is encrypted between peers.
The threat model is basically two fold though, in theory someone who has control of the ZeroTier roots (if you’re not using your own controller, if you’re using your own, then s/their roots/your roots/) could add routes to your devices, and add/remove devices that are part of your confirmation.
The encryption also doesn’t currently have perfect forward security, so if there’s a compromise in one of your connections, in theory some past state of that connection could be decrypted. In practice, I’m not sure this matters as traffic at a higher level for most sensitive things uses its own encryption and perfect forward security (but hey maybe you have some software that doesn’t).
The other thing I will note about that last point is that they’re working on a rust rewrite that will have updated crypto, including perfect forward security.
FOSS just means the software is open source. As I said, you can self host ZeroTier and not involve their servers (if you’re not doing things commercially, you pay for the license but still run your own controllers, or you use an older version which has been automatically relicensed by the change date to Apache 2.0).
That said, the traffic is peer-to-peer, in the majority of use cases there servers are acting as a bit more than syncthing’s servers (acting to facilitate the connection between two devices that want to talk together). See the other comment for some more thoughts here.
You got it right, lots of drama, not really anything to worry about unless you’re very fringe and have people you email via PGP with “super secure” PGP keys (and honestly I’d trust Proton more than I’d trust most people to roll their own PGP… it’s hard stuff to get PGP right).
I’ll pitch ZeroTier instead, it’s the same concept, but it’s more FOSS friendly, older, doesn’t have the non-networking “feature bloat” of Tailscale, and can handle some really niche cases like Ethernet bridging (should you ever care).
Just:
- Go to their website, create an account, and create a network
- Add ZeroTier to the devices you need to connect
- Enter your network ID on those devices
- Approve the devices in the web control panel
If you want to go full self hosting, you can do that too but you will need something with a static IP to control everything (https://docs.zerotier.com/self-hosting/network-controllers/?utm_source=ztp) this would replace the web panel parts.
You can also do a LAN routing based solution pretty easily using something like a Raspberry Pi (or really any Linux computer).
Is it though? It’s almost a pendantic quirk of the written language that things need spelled differently that sound the same.
Like, we ask know what you mean if you say “I was talking to the Johnsons and there cows ran away. Its total madness in this town lately.”
You could checkout a very similar product, ZeroTier (Open Source Community Edition) assuming your use case is non-commercial.
… if you’re willing to use an older release, you could potentially do whatever you want as the software uses a BSL license with a change date fallback license of Apache 2.0.
