cl_autoswitch_weapons & cl_autoswitch_weapons_out_of_ammo were displayed twice with both values, default is 0. cl_flow just doesn't exist.

@ZombieToad if i remembered how :/

help i stole ddnet code for my server and now everyones eyes are angery

sounds like a feature not a bug

07:40

we are all angry at you

lmao

I just started DDNet GER Halloween, can anyone confirm that it's running?

07:41

and working fine?

Image attachment

07:46

cant find them on ddnet tab tho

refresh?

07:47

it takes 2 refreshes to refresh btw

07:47

since we download the updated serverlist.json, but still use the old one in parallel and don't reload once the new one is loaded

07:48

otherwise there'd be an annoying stuttering while refrehing

07:49

@noby it actually is a feature btw, sv_events

i refreshed like 10 times

07:49

still nothing

ty lol

@Ryozuki thanks, looks nice

@deen i think forum also had theme

08:32

i remember it being orang-ish

08:33

cant find it tho

I see it in forum settings

08:35

but I guess it hasn't been updated

08:36

yeah, looks broken

hmm where is the source ?

08:36

maybe i can try updating it

don't know

08:39

actually I guess that's the problem

08:39

during some update it was deleted

08:39

so that explains why it doesn't work

08:39

I'd hope @Soreu has the code somewhere?

uh he has been inactive for long.. i doubt he will answer xD

I'll just ask him on Facebook

08:45

Maybe we should just keep the halloween design all year

https://web.archive.org/web/20130816180616/http://ddnet.tw:80/ lol, bad luck it didnt crawl ddnet on 31 october

well, you can always request a crawl

08:47

https://web.archive.org/web/20181031084718/https://ddnet.tw/ Just did one, so there you go for the future

or have a cookie to switch between dark/white

Soreu said: "Sadly I lost it with moving on new PC

But it wouldn't really work, since it was made for the older version of phpbb theme"

?

nvm

btw: rip zombie mods 0.7

@Ryozuki cuz I don't have source files, and trying to do all in css xd If only i had more time that'd be easier xd

13:12

@deen wait, you said it is in forum setting, but broken. that might be enough for me, depending on what's working, so gonna check it now

13:17

damn, far too broken xd

all the files are missing

13:56

just the entry is still there :/

there are build instructions here

Thanks Jao

@Vexar Not without adding in another library or using openssl. We only have md5 and sha2 in source

@Ryozuki not normal iirc, but @heinrich5991 would know better

@Learath2 np i already fixed my problem :D

@Learath2 is the anonymous enum stored in the struct? a.k.a saved in the map file too?

Image attachment

17:35

tee_thinking

I'd think it wouldn't be stored tbh

17:40

but it's scoped

17:41

Hmm as a struct member you can access it like CMapItemGroup::CURRENT_VERSION :/

i think its not stored

17:42

the code uses version to read it

Image attachment

Oh yeah it's not stored

17:43

The thing MapItemGroup inherits from has a member we ise

17:43

use*

yep

@Learath2 if you still looking for things to do, qshar would say hookprediction

I don't like doing anything prediction related :/

@qshar i tried

[ddnet-web:master] 1 new commit

0bae878 Version 11.4.5 - def-

Nice that you have some free time and willing to put it in ddnet tho

feelsbadman

Is hook even properly predictable? No way to know when the hook will be shot, no way to know when the input will cease

17:57

You can only predict the intraticks which I'd think we already to predict

implement moving tiles, then it will predict feelsamazingman

feelsamazingman

17:59

Or autologin feature in DDNet client should be really great

Well after we get a proper account system I'd like to think there'll be no need to log in to servers

what is the your idea of proper account system?

! changelog time

something like using facebook account?

Certificates

ew facebook

No way we are doing social media accounts

i dont have that

me neither :)

ed25519 account certificates

18:02

Server has a list of public keys, server sends challange, client signs challange + ip + some session_id sends it back, server now knows for certain which user it is

Me neither feelsamazingman

feelsamazingman

Server then advertises the pubkey fingerprint for verified users which other clients can use to match against their friendlist

why do you need ip

Prevents MITM

18:06

e.g. client uses what he believes is the ip. server uses what it believes is the ip. the signatures can't possibly match

hm.. You gonna need to implement IP detection to client and server sides

Well the client already knows the IP it's connecting to

I thought he sends his own IP

I haven't decided on how to do it on the server yet. Maybe someone else can find me a better way to mitigate MITM

18:08

Maybe doing everything over TLS

18:09

But then might aswell move the game protocol over to DTLS. But then can our weak servers support DTLS with many players. But then many other questions I didn't find the answer to yet

18:10

I'm basically thinking of stealing SSH currently

well, choosing low number of rounds and a good salt might do the job

18:10

xD

18:11

but anyway it is not clear for me how will you detect the person. Is it some kind of data that identify the client / computer?

The signature of the challange. The player claims to be X, he will prove that by saying he owns the private key corresponding to X

18:12

We have a list of public keys. We find the one corresponding to X. He signs the challange. We check if the signature is legit with the public key

18:12

If the signature is valid the user is X if not he isn't X

ok, but then if he remove teeworlds, then his signature (private key) will disappear as well (edited)

Was thinking BIP32 like nonces for that. You get a 6 word recovery key

18:14

You write them down, you can use it to recreate your private key

and also user has to transfer his pk (private key) to all computers where he play

He just needs to write his recovery key in

[ddnet/ddnet-web] Pull request opened: #65 changelog for 11.4.5

and he can't login on someone elses computer

I was also thinking of maybe storing the private key on ddnet.tw encrypted by a password

well, this will be a long key that will consists of many hard to remember chars

So we can't access it but the user can access it

18:16

That's why I said BIP32 nonces. It's like pirate knife potato germany cheese woman

18:16

you write that down, we derive the loong key

that just makes the system more complicated, but I think you can do both /login [pass] and the certificate

./login [pass] involves a central authority and uses plaintext tw chat

ye, I get your BIP32

e.g. fake servers that collect [pass]

they can't collect it if player uses autologin

18:19

but if they write in chat - then yes

Well best we can do with autologin is setting up an ip whitelist

18:20

Then ddnet becomes a central authority on where you get to log in

just sign (password+serverIP+a lot of salt)

If you let clients choose which servers to autologin on then it's open to faking attacks again

18:20

What are you signing with though? If only the password is enough to log in

18:21

sha2(password + serverIP + salt) would work though, but at that point a normal user cant login with chat

18:21

only autologin

well, he should be able with both - autologin or write in chat. Yes, writing in chat is not secure, but it will work when player is not at home

Well with certificates he can login anywhere with ddnet client as long as he can remember or writes his 6 words

this is just like password, but a bit more complicated to remember

Yes but you never write it anywhere public

18:25

It's never transmitted to a server

thats true

Especially not to a teeworlds server, which are very easy to fake

18:26

Anyways I still need to iron out many things and it helps to discuss it with people

:)

18:27

by the way, how are you gonna handle situation when 2 brothers play on the same computer

How often does this happen anyways? Just an account selection in settings I guess

ah, acc selection does the job indeed

what about a /login ? xd

What about it?

18:38

If you have certificate based authentication no need for a command. Ifyou are using it to send passwords you are sending them out in plain text which opens them up to pishing and allows for bad passwords which gets people hacked

multiple accounts for one device should definitely be a thing

Not that hard to make that happen after we have a system in place

Hu yeah k

status from fifo doesn't show addrs... thanks obama

maybe try borderless or fullscreen

teeworlds networking really craps out with random data

settings file

@uu vanilla client works? inp_mouseold 1

20:08

(f1)

20:10

sounds like lots of problems

@uu no on vanilla you should look at filters

20:10

And turn gamemodes on/off idunno

and turn off software firewall

20:11

and check if other udp games work

ey i already tried to help him

20:14

The problem is that he doesn't have appdata/Teeworlds

20:14

So no settings_ddnet.txt

20:14

but i sux so idk

sounds like missing file permissions

20:14

try running as admin to see if that's it

btw it would be nice to have the "controls" windows showing the actual keys and not the qwerty version

no cause u need to know what enter in f1 , so showing qwerty version that F1 use is fine imo

Hmm, I might add a http server to ddnet

What do you mean "what enter in f1" ? In my controls, show all is set to "semicolon", on my keyboard it's "m" and when i press "m" in f1 i get "m"

21:18

i mean f1 doesn't use qwerty

When i wanna bind keys like $ i go to controls and bind it to a random action to know how it's called u know ?

Yeah i do that too

If u have an azerty i guess u french ?

yup

right
