is it possible to increase the number of characters in a message? Because sometimes you click send, but the message is not sent and you have to erase it gradually

client and server should ideally have the same limit

07:30

but I believe the spam detection might get into your way there

07:31

Just tried it and without spam protection (no messages sent by me before I can send the full length message client allows

07:32

but then on the next few attempts spam protection comes in if I don't wait long enough between messages

[ddnet/ddnet] Issue opened: #5670 Handle common teehistorian problems

Currently if the disk gets full teehistorian will still keep trying to write, even though at that point we've already lost enough data that the file would be useless even if the write succeeded. This also causes flood in rcon making the rcon impossible to use. Solution: If a write fails there is no recovering, close the file and disable teehistorian recording. Due to the nature of the format, I don't think we can ever start a new file from an already running server. Another common problem ...

@deen so sad noby & me worked on it

What about making a web client inside ddnet client and verify there with recaptcha?

14:49

Before joining server, it pops out

14:49

Better than going on external browser

Tf not needed

And only ddnet verified servers can send “I’m not robot” pop out

14:51

Hm okay, but ddnet client needs something refreshing. This is started being boring.

14:52

At first point it’s sad that this verification is even needed

14:52

Ddnet client needs new UI support sent by servers

14:53

Custom text boxes on UI, etc…

Lets make a super fast client slow and bloated by adding web

14:53

Web ui like windows 11

Nah Ryozuki, u don’t get the point like 90% of the time. But whatever

This is actually interesting. I do have a prototype that allows rendering information boxes from the server, but I found it way too rigid to do anything with

Not useful for much more than help boxes for things like tutorials

Look, even login ui could be cool (edited)

Anti ddos, it’s sad that people still doing it. Killing game

Anti ddos, it’s sad that people still doing it. Killing game

Yes I know, that's why I'm trying to work on that dynamic way to whitelist someone when he's in for more than 5min

15:01

That could also semi-fix the issue deen had with those people having different IPs

15:01

People who were already ingame will be whitelisted already by their real IP

I had some very annoying issues with moving hookthru tiles and rq’d it

Lol I guess so yes, looks hard

ReiTW

Yes I know, that's why I'm trying to work on that dynamic way to whitelist someone when he's in for more than 5min

Why don’t you utilize a secondary daemon to keep track of play duration and use the reporting socket we have?

reporting socket?

The problem is that ddnet client is open source, it could be possible to prevent ddosing by verifying player then run launcher and send few info to server to whitelist it (edited)

ReiTW

reporting socket?

I don’t remember how we named it in the code, but the server reports joins and leaves to a configurable unix socket

no clue, but my goal is to be able to manipulate maps using a Rest API

15:03

so you could PUT a specific API path to add an IP into the whitelist

m!ki

The problem is that ddnet client is open source, it could be possible to prevent ddosing by verifying player then run launcher and send few info to server to whitelist it (edited)

We tried, a lot of people have mismatching udp and tcp ips due to cgnats/vpns. So whitelists aren’t exactly easy to do

Cgnat is so gay

and having to https request an API to whitelist someone after being ingame for 5mins is easy I think

ReiTW

and having to https request an API to whitelist someone after being ingame for 5mins is easy I think

I would offload that to an external daemon so there is no extra code in the server to maintain

15:05

We already report joins and leaves to a unix socket, you can hook your daemon there and it’d be a plug and play solution for any ddnet based server since ddnet 10 iirc

I could do smth based on that socket yea

Ye, but maybe launcher handshake with server, but hidden and encrypted. But still it’s boring to making external software to play game

️

thing is you still have to do another way to whitelist when under attack, like a website or that client-side verification. Even if people who has mismatching udp/tcp IPs during attacks, that's better than whitelisting everytime through https (edited)

m!ki

Ye, but maybe launcher handshake with server, but hidden and encrypted. But still it’s boring to making external software to play game

️

We don’t need a launcher, the client is completely capable of doing a handshake. The problem is that the ip people do the handshake on won’t match the ip they join the server with

but attacks are generally not permanent, so not that bad

Make ddnet private source, and done job

1

Doesn’t matter that it’s open source

But how aren’t other games affected by massive ddos then?

I'll take a look at your socket, but will still learn to make that Rest API (as I will need it for a school project + XDP)

15:09

other games are affected too

ReiTW

but attacks are generally not permanent, so not that bad

Anyway, in our case the issue isn’t whitelisting. We can figure that out just fine. The problem is no matter how good we are at filtering, our cpus and connections are just not fat enough

m!ki

But how aren’t other games affected by massive ddos then?

Step 1) Invest tens of thousands of $ per month into ddos protection. Step 2) Profit

ReiTW

other games are affected too

Sure, but it’s harder cuz idiots don’t have way to make shit scripts to emulate client and spam servers

I'd say easier

as an old idiot I can confirm that

Oh, which bot did he make?

Ubisoft's games, EA's etc..

they're not

And you managed to kill their servers?

when I was doing tests & shit yes, for a few sec, but I switched to the good side

15:12

Even told it to potato from my team who works at Ubisoft lol

Learath2

Step 1) Invest tens of thousands of $ per month into ddos protection. Step 2) Profit

Which one? Cloudflare?

cloudflare is way too expensive

m!ki

And you managed to kill their servers?

The ability to generate traffic is not the issue. You can generate legitimate looking traffic by just reverse engineering. The key to their success is their massive infrastructure. You can easily take down one server with ddos. It won’t affect the thousands of running games for other people

I think it's called cloudflare magic smth?

However, we got the point. ReiTW get cloudflare proxy and ur good

Invest in protecting main proxy

I was just kidding, lol, take it easy. As i've told you a thousand times before, i would never do anything with your mod (i don't have it anymore tbh)

I could host one proxy node if this will even exist & be used, but I doubt people trusts me today sadly

m!ki

Or make one big tw entry proxy for other tw servers

We have this as a long term plan. But instead of a main proxy, a hierarchy of proxies that we can shift load between

Something like BungeeCord for minecraft

@m!ki yes when I asked about https://github.com/ddnet/ddnet/issues/5662 I was thinking also about giving bungeecord as an example

does bungeecord actually redirect to another ip or is it just like proxies?

thing about proxying is it has to be simple enough to stay easy to setup a server without it too

Tater

does bungeecord actually redirect to another ip or is it just like proxies?

No, ur still on entry proxy

15:26

It’s not just redirecting

yea

ok

it's not a feature implemented client side

15:27

(I think so)

If proxy that u connected to is dead, then ur out

15:27

However, bungeecord is so cool shit, best thing made in mc

it's all about faking, on teeworlds you can just fake a change map & switch someone to another server instance

ye no hypixel without bungeecord xd

@Learath2 btw I was always wondering why having always 2 commands like super and unsuper ? why not a single one that can toggle?

Only greyfox or 3da probably know the reason
