i didnt drink or go to toilett or move for 8 hours lol

06:16

xd

staying hydrated is important especially if ur not sleeping lol

was busy chillin in some queue

@fokkonaut it used to be possible, but now the client gets its news, ddnet server list and newest client version all together from https://info.ddnet.tw/info

@noby you don't want the spam we recieve with /modhelp

did u get my message

@fokkonaut I can't see the version update thing in wine

08:23

but if you're on the 64-bit version of ddnet on windows, try replacing the 85 with a 31 at offset 0x5b911 with a hex editor

08:23

(make a backup first)

08:23

in the file DDNet.exe

08:24

eh nvm, this was version 11.2.1

08:24

let me download 11.0.3 (that also explains why I didn't see the version warning)

08:29

@fokkonaut do the same at offset 0x5f8bd

08:29

i.e. change the 85 with a 31 at offset 0x5f8bd in DDNet.exe, version 11.0.3, with a hex editor (edited)

is A* the best path searching algorithm for 2d?

it's pretty good, depending on what you need

08:57

e.g. on a plan with collision and without teleporters, it's optimal, I think

08:57

*on a plane

(not for ddnet, its more topdown view)

ban 5991 f3 GWqlabsFeelsGoodMan

@heinrich5991 what? xD

09:56

@heinrich5991 i didnt understand one word :D

09:56

coders lost all connection to reality

@noby ah the /modhelp channel is gone :0

@fokkonaut we figured it out now

what?

11:27

ah yes xD

a hex editor for windows is e.g. http://frhed.sourceforge.net/en/

Frhed - Free hex editor

Frhed is an binary file editor for Windows. It is small but has many advanced features like ability to load big files partially.

no more forum nor discord on website?

12:51

huh?

Hey guys, did you read what I wrote some days ago about ninslash ?

@heinrich5991 if you still didn't find the reason of long connecting, try to check the server time. If the time was changed when game servers were up - it might cause this problem.

@heinrich5991 wasn't the TKEN stuff meant to stup the join flood?

13:15

can't take up a slot until you respond iitc

it's an fng server

they do it with ddnet aswell

you guys found the problem why we cant join ger?ű

Not only ger, i cant join rus as well (edited)

saw one where snail was alone and the rest of the server was flooded

why the server allowes limited people

13:17

wth

are the ips all from the same type of ranges?

we can't snap a billion players

like server hosting ranges specifically

we didnt say a billion, only a few hundred

13:17

isnt big number

but then people could just scale the attack up to that number?

i think anyone who can ssh into that server could see which ips are trying to connect in console

could be a solution for reboot the system?

13:20

then it refreshes datas and stuff

no

13:20

but in some cases blocking the offending ip ranges in firewall can help

is it 100% works or just a tip for faster connecting

? im talking about the ddnet rus fng server that seems to be flooded with fake connects

oh shit

13:24

never knew that stuff

where did the forum go xd

forum.ddnet.tw

look

13:34

my catalonia flag search

13:34

XD

xD

https://forum.ddnet.tw/

i dont actually want to go to the forum

13:35

just wanted to point out

[ddnet-web:master] 1 new commit 42ef0fd Remove links to inflammatory Discord channel and inactive forum - def-

dont see a point in that

13:40

no one benefits from it

13:40

tbh

13:41

just a small amout negativly benefits from that

13:41

but who cares

13:41

xd

13:41

btw whats the word for negativ benefit

drawback

ah ok

can you blame the guy?

who

deen, it is pretty darn negative in here

idk deen

13:43

i talked with him

13:43

like

13:43

5 mins over phone number

13:43

xd

I dont know if it fits here but: I cant connect to GER nor RUS servers. CHN, CHILE, USA and CANADA works fine. Alrdy restarted router, changed DNS but nothing seems to work. Any ideas whats the problem?

It's the join flood tripping the ddos protection, try vanilla

Does not seem to work either.

14:03

well guess there is also a ddos going on

just play

14:04

on chile server

14:04

xDDDDDDDDDDDDd

14:04

k thx tho

@Learath2 what is gauthreimport?

@Ryozuki catalonia has a gay flag tho

@ZimE a tool that regenerates the QR codes for the 2 factor auth secrets from the database file

@ezy legends say it was made by a man with 4 fingers in blood on a shield while he was diying

reboot the system and delete sytem32 monkaS

delete system33

@Learath2 where you get the databasefile

why did he remove links to the discord channel

You can download them on ddnet.tw @ZimE

from the website

@Deleted User aparently this server and forum is cancer

@ZimE you can get it on a rooted android phone

@Learath2 whats the goal with this tool, i dont understand

Google authenticator makes it pretty hard to move to a new phone

there is no catalonia flag in

14:15

discord

14:15

disrespect

so I made a tool that extracts the data

14:15

so I can re-add it on my new phone

isnt 2FA optional?

optional if you want to get hacked

@Learath2 authy is better

14:16

google auth sucks if u lost mobile and the codes

but then what's the point of 2fa? if you can restore all your 2fa codes with one username and pw

14:17

then your security just has one extra password

i dont know how it works

Lol if you loose your phone and codes you deserve it xd

@NeXus shhh no

yes

github has a no tolerance policy about it

14:18

if you lose it they won't help you even if you give them legal id and credit card you used for payment

some people on other servers tell me, that there were donations stolen on ddnet, that's why this is happening

14:19

dont know anything about it, just sayin

I'd feel even safer if I could have a device just for 2fa

yikes stolen

how stolen

@Deleted User no need for conspiracy theories, all donations received and where they go is put up on /funding

just transported it from there to here, dunno anything

14:21

so you know what tees are writing out there

If any donation was missing on /funding the person who donated would complain, if any of them hadn't went to where they went to we'd have servers shut down because we didn't pay for it

just use stronk password, no need 2FA

well if you use 2fa, even if someone finds your stronk pw you are fine

isnt it possible to change to a big hoster like amazon who can scale the power for ddos ?

AWS isn't cheap

14:29

also game servers don't really scale that easily, can't just load balance

fix servers

why not reboot it

14:48

what could possibly be worse from it

14:48

losing data or smth?

nah

14:50

mostly using active players

14:50

I don't think that rebooting the server will help though

nobody have fun right now

14:53

they are just there, cuz they are always there (edited)

14:54

tryin something cant make it worse

14:55

hi friend @heinrich5991

14:58

Too complained

no vpn to help the server, no rebooting to help the server, what really helps the server tho?

No problem with joining

15:14

Omg nice setup feelsamazingman

da hall

15:16

now... i can too

15:16

did you just fix it or it was automatic

15:17

w8 (edited)

Btw using ddnet 10.8.6 and joined in normal time

nevermind

15:17

i guess i know my problem

15:17

i have connection lost on some servers which are cannot enter me

15:18

otherwise there are other servers that can let me join

conn_timeout 100

15:18

lol

Guess i was lucky, cant join anymore xd

make a test for try joining to every server

idk why i did it , but useful at some point

Testing_DDNet_Servers_Connection_Capabality.txt

371 bytes

15:37

oof

[quakenet] <deen> Yuzu: To clarify about "stolen donations". Everyone who doesn't specify their nickname in the donation gets an email from me asking about how they want to be credited. Some never reply to that email, one had a disabled email account.

[quakenet] <o_be_one> (i confirm im in credits since long time!)

I cant see ger Servers

17:35

17:35

And cant join ofc

17:40

Is there a ban on 79.210.94.25? feelsbadman

@ᶰ°Konͧsti might just be the general non-connectivity of ddnet servers right now :/

@Learath2 have a bit of time to talk about http masters?

[quakenet] <Learath2> sure

18:30

[quakenet] <heinrich5991> k

18:31

[quakenet] <heinrich5991> so my current design looks as follows:

18:31

[quakenet] <heinrich5991> servers register with all master servers, clients check one master server to get all servers

18:31

[quakenet] <heinrich5991> servers send info to master server, every time it changes (with some backoff, maybe)

18:32

[quakenet] <heinrich5991> (that stuff all happens in json, btw)

18:32

[quakenet] <heinrich5991> as a change from the previous protocol, a server is allowed multiple addresses (for ipv4+ipv6 support)

18:33

[quakenet] <heinrich5991> [maybe that should be restricted to "at most 1 ipv4 and 1 ipv6 address, at least one of those"

18:33

[quakenet] <heinrich5991> ]

18:33

[quakenet] <deen> player names and scores? do servers keep an http connection to the master open to keep pushing updates or make a new connection on each change?

18:33

[quakenet] <heinrich5991> the PR above lets curl reuse connections

18:33

[quakenet] <heinrich5991> (and it actually does that, I checked)

18:34

[quakenet] <heinrich5991> for backward-compatibility, the masters also send the list of other servers (only their IP addresses), for the client to ping individually

18:34

[quakenet] <heinrich5991> this will be extended by running a serverinfo fetcher on the masters later, so that this list of IP addresses can be dropped eventually

18:35

[quakenet] <heinrich5991> possible extension: some sort of live-update protocol over TCP where the clients only get the changes, instead of downloading the whole list again

18:35

[quakenet] <heinrich5991> the master server would be a process that updates a 'static' file in a reasonable interval (maybe 1 second or so), for the webserver (like nginx) to serve

18:35

[quakenet] <deen> why not over https and just use some json diffs thingy?

18:36

[quakenet] <heinrich5991> yes, https

18:36

[quakenet] <heinrich5991> oh, you mean the diff stuff

18:36

[quakenet] <deen> yeah, you said tcp

18:36

[quakenet] <heinrich5991> yea, that sounded like it was more fit for TCP

18:36

[quakenet] <deen> why?

18:36

[quakenet] <heinrich5991> if you want live updates instead of updates on client pull

18:38

[quakenet] <heinrich5991> but yea, that part isn't as important to discuss, we can do that later when the rest of the stuff works

18:38

[quakenet] <Learath2> hmm

18:38

[quakenet] <deen> well, it would be nice for live notifications of friends joining

18:38

[quakenet] <heinrich5991> true

18:38

[quakenet] <heinrich5991> could be abused though, this part

18:38

[quakenet] <heinrich5991> without having cryptographic user identities

18:39

[quakenet] <Learath2> am I following this correctly? the master now also has all serverinfo so people don't have to getinfo?

18:40

[quakenet] <heinrich5991> yes

18:40

[quakenet] <deen> so no more accurate ping?

18:40

[quakenet] <heinrich5991> yes

18:40

[quakenet] <heinrich5991> we can add a checkbox to ping servers

18:41

[quakenet] <deen> sounds good

18:42

[quakenet] <heinrich5991> cool. Learath2?

18:42

[quakenet] <heinrich5991> :)

18:42

[quakenet] <Learath2> without the liveupdate stuff, sound's like it might be a lot of traffic

18:42

[quakenet] <deen> without the liveupdate just update when user presses refresh

18:42

[quakenet] <deen> should be less traffic than currently

18:43

[quakenet] <deen> only 1 connection, 1 GET, compressed json

18:43

[quakenet] <deen> and can trivially be put behind some cheap anti ddos

18:43

[quakenet] <heinrich5991> yes

18:44

[quakenet] <heinrich5991> that was part of the requirements

18:44

[quakenet] <heinrich5991> that it would be possible to be put behind the free cloudflare offering

18:44

[quakenet] <deen> well but that's why I wondered why you said tcp :D

18:44

[quakenet] <heinrich5991> diffs are dynamic in nature

18:45

[quakenet] <heinrich5991> well, I don't know. let's call that extra for now, and let's see how far I get with the rest :)

18:45

[quakenet] <Learath2> I don't see any problems with it btw, sounds nice

18:45

[quakenet] <deen> what about vanilla servers?

18:46

[quakenet] <heinrich5991> [20:34:14] <@heinrich5991> for backward-compatibility, the masters also send the list of other servers (only their IP addresses), for the client to ping individually

18:46

[quakenet] <heinrich5991> [20:34:42] <@heinrich5991> this will be extended by running a serverinfo fetcher on the masters later, so that this list of IP addresses can be dropped eventually

18:46

[quakenet] <Learath2> we first provide a list of ips

18:46

[quakenet] <deen> but vanilla servers will only register on one master, not all

18:47

[quakenet] <deen> so the master has to get the list from all other masters?

18:47

[quakenet] <heinrich5991> yes. the backward compatibility stuff has to fetch IPs from all 'legacy' masters

18:48

[quakenet] <Learath2> are the cheap ddos solutions good enough for 1 sec resolution?

18:48

[quakenet] <deen> so a potential attacker can still register their vanilla server to get all ip addresses of tw players

18:48

[quakenet] <deen> what about having the master fetch player counts from legacy servers too?

18:49

[quakenet] <heinrich5991> yes

18:49

[quakenet] <Learath2> yeah a fetcher would isolate that

18:49

[quakenet] <heinrich5991> the extension will fix that

18:49

[quakenet] <heinrich5991> but my experience shows that I have to do work with milestones

18:49

[quakenet] <heinrich5991> to get anything done

18:49

[quakenet] <heinrich5991> in fact, the curl sharing stuff was just extracted from my WIP http masterserver branch ^^

18:50

[quakenet] <heinrich5991> maybe we could use my already existing rust tool for fetching vanilla server infos. I'd need to extend it for 64p stuff though

18:51

[quakenet] <Learath2> I was also seeing if there was any ip re-use during the join flood but there appears to be none

18:51

[quakenet] <Learath2> so it most probably is spoofed

18:51

[quakenet] <heinrich5991> k

@noby ^

[quakenet] <deen> heinrich5991: stealing ideas from the mozilla playbook? integrate some rust into existing c++ project with lots of legacy code? ;)

18:58

[quakenet] <heinrich5991> nah :P the master would probably run in python or so, I'd guess

18:58

[quakenet] <deen> we have existing fetch code in c++ already

18:58

[quakenet] <deen> why not c++?

18:59

[quakenet] <heinrich5991> you mean the client code?

18:59

[quakenet] <deen> yes

18:59

[quakenet] <heinrich5991> it looks messy to me

18:59

[quakenet] <deen> it is

18:59

[quakenet] <heinrich5991> and if we're going to code a new master anyway, we can just code it in python

18:59

[quakenet] <heinrich5991> I think that sounds appropriate for a http endpoint

18:59

[quakenet] <deen> what about performance?

18:59

[quakenet] <deen> agressive caching?

19:00

[quakenet] <heinrich5991> the server list is written to a file, for nginx to serve

19:00

[quakenet] <deen> or about millions of servers trying to register in an attack

19:00

[quakenet] <heinrich5991> that way, the python script doesn't have to perform very well for the clients

19:00

[quakenet] <heinrich5991> yes, that could be a problem

we probably should keep it C/C++ imho

[quakenet] <heinrich5991> I don't have a go-to-language for high-performance http applications ^^

19:00

[quakenet] <deen> c++

19:01

[quakenet] <heinrich5991> I personally don't want to write new internet-facing services in C/C++

19:01

[quakenet] <deen> what's the difference if it's an http application or a game client/server?

19:01

[quakenet] <heinrich5991> currently, I'd probably either look at go or rust

19:01

[quakenet] <heinrich5991> the new thing

19:01

[quakenet] <heinrich5991> I wouldn't want to write a new internet-facing game in c/c++ either

19:02

[quakenet] <deen> so you're not going to contribute any more c++ code?

19:02

[quakenet] <heinrich5991> I am

19:02

[quakenet] <heinrich5991> but I don't really want to start a new codebase in c/c++, if I don't have to

19:02

[quakenet] <deen> just not if it lands in the mastersrv binary?

19:03

[quakenet] <heinrich5991> the existing code for mastersrv is pretty much nothing, one could check whether one could reuse the browser code

19:03

[quakenet] <heinrich5991> i.e. the existing master server code doesn't help writing the new master server

if we are carebul about it, It shouldn't be too tough to make sure this is safe

[quakenet] <deen> ^ famous last words

19:06

[quakenet] <deen> I can understand the unsafety issues heinrich5991 has tbh

19:06

[quakenet] <deen> especially since we use C with classes and not exclusive modern C++17 without raw pointers etc

I mean it's pretty much the standard for low-latency applications

19:25

this tech team seems outdated

19:25

if some1 needs some tech contact imo heinrich is a better spot to visit than HMH

:p

who the hell is HMH

19:26

lol

xd

19:26

see?

i prefer heinrich over anyone

19:26

he is my favourite

ik worst is troll but HMH was some active dude but i havent seen him in ages

?

19:26

I'm not a troll

I miss east

who is east (edited)

random

admin

19:28

also here should only be jao

gdin should be tech

did he do some tech?

19:30

i didnt know dinner is invloeved in any tech stuff.

19:31

I actually have no idea what dinner does except doing yt and playing good c:

I guess you can make a PR adding jao to the community team, if you want

I'm not admin

19:54

k nice i will probably do it during my camping trip

20:23

hopefully i can get internet there

20:38

lol

20:38

rip modhelp

i think ddspeed is the author of the ddos

21:07

wtf

21:10

what is even the point of it

21:10

on a non lucrative game...

ddspeed.ovh is not valid

21:10

.-.

ye

nobos

32 slots servers sounds interesting tho

anti ddos

21:11

xd (edited)

no i mean actually

21:11

gameplay-wise

21:12

maybe its a good compromise

no sucks

why

64 isnt enough

21:12

so 32 isnt better

a full 64 server is rly spammy

21:12

and blocky

32 is good

block is nice c:

21:12

just fix maps

my server is only 32player

not on ddrace

21:12

block is nice on block

block is a bad thing pretty much everywhere except for block servers

if u wanna block go block

it's annoying if u can't join a srv

yes

i would love to see 128 servers

whats nice in fighting people who just wanna race

21:12

with each other

21:12

lol

imagine trying to votekick someone when u need 64 f3's

xd

@ChillerDragon i think it doesnt work rn tho

ye i know it

21:16

ddnet++ has stole it already hehe

[quakenet] <heinrich5991> nighty night :)

?

[quakenet] <heinrich5991> good night ^^

22:29

[quakenet] <heinrich5991> I'm going to sleep

night heinrich

good n8 bro

22:31

important dev info

22:31

i guess ima tell u every day when i go to sleep in #dev now :p

no idea to where report this info so I leave it here: link to forum missed on ddnet.tw website

nothing new

23:18

deen made that

good night
