<Henningstone> <Learath2> how is nimda supposed to stop anything if it +v's everyone so quickly? :P

00:28

<Henningstone> apparently she does actually know whom to +v, because Condiment was ignored where Edible did get +v

00:28

<Learath2> Henningstone: we had this conversation with heinrich5991 a couple of days ago

00:29

<Learath2> guess Nimda has some kind of algorithm by which it determines who is worth

00:29

<Learath2> y

00:30

<Edible> first come first served then

00:30

<Learath2> guessing ip close enough or exact matching user@host or simply all nicks that were here before the lockdown

00:30

<Edible> same ip too

00:30

<Learath2> or maybe it keeps a list of regulars

00:30

<Edible> or maybe its about who's authed?

00:30

<Learath2> no i saw it +v people who werent authed

00:31

<Edible> oh, i'm not authed currently

<Ryozuki> hi

14:06

<heinrich5991> hi

some guy is trying to connect to tw servers but it doesn't downloads the maps, his english is not so good, basically what happens to him is that map download doesnt starts https://youtu.be/h19cQW8NeqA?t=65 he made a video xD

DDNet, other server I can't join!

16:20

@10100110101Hacker101101101011 you should try to speak this here, maybe they solve ur problem

16:21

<deen> Learath2: ^ downloader problems

16:34

<deen> Ryozuki: as a workaround the guy can disable http map download in settings -> ddnet

16:35

<deen> he has a libcurl.dll.old lying around, maybe libcurl problems

16:36

<deen> or permissions problem

16:38

<Ryozuki> idk it would be to hard to explain this to him, maybe some russian can help him more

16:40

<Ryozuki> hmm disabling http download doesn't work for him either

16:42

no space on hard drive

16:42

(y) definitely

<Ryozuki> could be

16:42

<Ryozuki> sec

@Savander You see YouTube?

Yes, why

16:43

<Ryozuki> he send me this

16:44

<Ryozuki> i guess he have space

16:44

<Ryozuki> i don't understand russian :/

@Savander why can't? join (edited)

yea, he has a lot of space

16:44

1.4 TB

16:44

hmm

wtf

<deen> Then wrong permissions

oh, maybe right

16:44

my disk E: 1,26 tb

<deen> (make backup of settings)

@10100110101Hacker101101101011 try to run ddnet as administrator

<deen> Learath2: can we have a nice error message if no space or permissions are wrong?

you see youtube have video administrator

16:45

you see (edited)

<deen> Hacker: can you show the log output?

@10100110101Hacker101101101011

Image attachment

@Ryozuki he did it

<Ryozuki> when word dont work images are better

16:46

<Ryozuki> oh

hmm

16:46

curious

16:47

maybe firewall somehow prevents him from downloading

16:47

hmm

<deen> f1, logfile "foo.log"

16:47

<deen> restart client

16:47

<deen> download map

16:47

<deen> send me foo.log

16:47

<deen> (file)

will be in main directory

16:47

right?

yea

or config_directory

wait

<Ryozuki> milk you there? xD

D

16:48

XD

<Ryozuki> he used to be in this irc i think

Game of Thrones s07 god !

16:51

@Savander @Ryozuki Done logfile foo.log {ENTER} Done Server Join can't(

<Ryozuki> now show us the logfile

16:51

<Ryozuki> send it on discord

I already can't

<Ryozuki> find foo.log

16:52

<deen> maybe no permission to write foo.log either :D

<deen> how to enable the cmd window on windows again?

16:54

<deen> cl_show_console 1

16:54

<deen> restart client

16:54

<deen> download map

16:54

<deen> screenshot of look at black window

16:58

<deen> but i think it's a general problem with saving anything, since it can't even save settings_ddnet.cfg?

16:59

<deen> one of his bot clients might have made the entire teeworlds config directory read only

that's possible

<deen> close steam

17:09

<deen> i remember something about steam locking directories

17:09

<deen> @10100110101Hacker101101101011

ok

17:10

Steam close done

17:10

17:11

<deen> close every other program you have, disable all autostart, reboot computer, reboot into recovery mode, reinstall windows, buy new computer, etc

:<

<deen> and don't install bots and "cool hacker tools" next time

police incoming

17:14

ijo ijo

<Ryozuki> woah bitcoin price is really high

17:16

<Ryozuki> $3,390.22 4.15%

imagine that you bought 100 bitcoins 6-7 years ago

17:16

17:17

RICH

sad i didn't

<deen> imagine we live in the other universes where bitcoin failed within the last 6-7 years, POOR

xD

17:18

5 bitcoin = 16950€, deen why would you need so much money? ^^

7 years ago, bitcoin was for few cents

17:19

i don't think, That i would go bankrupt

0.06€

right

that was bitcoin price

even 1000 bitcoins, don't seems to be so much

17:20

meh. I should be smarter! :<

17:20

but i was 14

time to look at new cryptocoins and buy them

17:20

etherum is the thing now

i saw

17:20

People says

17:21

"IT GONNA BEAT BITCOIN"

17:21

maybe

mm etheurm is 266€

17:22

someday bitcoin will die because of its dificulty

17:22

(i think?)

<deen> predicting the future is even more difficult

yea

17:24

you think digital currencies are better than real money?

<deen> me?

yea

<deen> I think they are a waste of energy and I won't support them

i see :o

<deen> people mostly use them for speculation right now, no one cares that you can only have very few transactions within a timespan and it takes long to verify

17:28

<deen> (being a waste of energy is not bad in itself, consider trees that generate millions of pollen, thousands of seeds and still only generate a single other tree from that.)

i'm not really into cryptocurrency, in fact i never did a transaction so i didn't know they were that slow

15 minutes i guess?

<deen> yeah, something like that

Like now, you are going to the shop

17:34

touch, DONE

<deen> and Ethereum is REALLY funny

17:34

<deen> where you can code a contract in something that looks like javascript

17:35

<deen> because javascript is "cool"

i see etherum heists in online news very frequently

<deen> instead of just having a simple decision table that everyone could understand

"Ether Thief Remains Mystery Year After $55 Million Digital Heist" xD

<deen> see obfuscated c contest for why this will be fun

that contest has nice ascii art

17:36

http://www.ioccc.org/

<deen> wait, sorry, wrong contest

17:36

<deen> I meant underhanded: http://www.underhanded-c.org/

:(

17:37

http://www.ioccc.org/2015/burton/prog.c

@deen @Ryozuki checked his permissions he is owner of %APPDATA%\Teeworlds, deleting did not help, autoexec is being ignored, settings also the directory remains empty (edited)

Anyone want to write the map name here and maybe even add a picture? https://ddnet.tw/tournaments/

18:14

It's pretty easy: https://github.com/ddnet/ddnet-web/blob/master/www/tournaments/index.html

ddnet/ddnet-web

ddnet-web - Static part of DDNet's website: https://ddnet.tw/

the name of the tournmap?

yes

18:17

and the small image from /ranks/maps/*.png

18:17

I think that would make it much easier to find the tournament you're looking for

<Ryozuki> ill try to add names web scraping with python

Guys, can you tell me how Teeworlds know that server have password or not?

18:30

where i can spot the code

18:30

Who is responsible for that

18:31

I remember that, heinrich has some kind of documentation about teeworlds protocol? no?

grep

<deen> SERVER_FLAG_PASSWORD

18:40

<deen> I guess

https://github.com/teeworlds/teeworlds/blob/0.6/src/engine/shared/protocol.h#L79

teeworlds/teeworlds

teeworlds - A retro multiplayer shooter

18:40

this?

<deen> yes

thanks

18:41

i found it a second ago

<deen> I just grepped for PASSWORD

18:41

i can't grepp

18:41

never used it

18:41

:/

<deen> grep -r PASSWORD src

no idea if i can on windows

18:41

:/

<deen> or "git grep PASSWORD"

git

18:41

oh

18:41

hmm

18:42

thank you

18:42

maybe i should learn a bit of that stuff

<deen> 99% of cases where people ask "how to do X?" I just grep for X

18:42

Magician

<Ryozuki> http://gnuwin32.sourceforge.net/packages/grep.htm

18:43

<deen> Ryozuki: meh, next you need sed and all the other unix shell tools

18:43

<deen> IDEs can also search for patterns I guess

18:44

<Ryozuki> you can download all gnu tools here https://sourceforge.net/projects/getgnuwin32/files/

18:45

<Ryozuki> C:\Users\Edgar\Desktop\ddnet\src (master)

18:45

<Ryozuki> λ sed

18:45

<Ryozuki> Usage: sed [OPTION]... {script-only-if-no-other-script} [input-file]...

18:45

<Ryozuki> i got it :)

18:45

<deen> with pipes?

tbh, i don't have teeworlds source at now

<deen> also "last modified 2011-05-31"

18:45

<deen> also "sourceforge"

18:46

<Ryozuki> https://sourceforge.net/projects/getgnuwin32/

18:46

<Ryozuki> this one is more recent

18:46

<Ryozuki> 2016

18:47

<deen> What about the linux-in-windows thingy? isn't that better?

18:47

<Ryozuki> bash on ubuntu on windows

18:47

<deen> mingw with pacman also looked reasonable for being on windows

18:47

<Ryozuki> i prefer linux ofc

18:47

<Ryozuki> but i like having things handy

18:48

<Ryozuki> yes it supports piping

18:48

<Ryozuki> im using cmder tho

18:50

<deen> anyone built ddnet on the bsds recently?

18:51

<deen> I hope we didn't add anything linux specific

18:51

<deen> bsd people don't have many games to choose, someone should submit ddnet to their packages

18:51

<Ryozuki> :/

18:52

<Ryozuki> is there someone using bsd here?

18:52

<deen> eeeee or fstd I think

18:52

<deen> I used to run the ddnet server on my OpenBSD server a few years ago, used to work just fine

18:53

<deen> libressl might require some #ifdefs

18:53

<deen> or not, since curl will be fixed already on openbsd

18:59

<fstd> Ryozuki: i run netbsd

18:59

<eeeee> have heard you don't have many games to choose

19:00

<eeeee> how do you live like that

19:00

<Ryozuki> teeworlds is enough fun :)

19:01

<eeeee> i once tried to use gentoo portage in cygwin on windows

19:02

<eeeee> it was a really shit experience because portage chmods files all the time and that's a really expensive operation on ntfs

19:02

<eeeee> other than that it worked suprisingly somewhat, actually managed to emerge some things

19:06

<fstd> the cygwin terminal is soo slow

19:07

<fstd> i bet that tripled the emerge time

19:07

<fstd> slow wrt outputting text, i mean

19:12

<deen> fstd: does the current cmake build of ddnet work?

19:14

<fstd> no idea, i haven't built ddnet in a while (and when i did, i used bam)

19:14

<fstd> i can test it when i have time

19:14

<fstd> need to build cmake first, though. i wonder what build system cmake uses

19:18

<deen> the previous version of cmake until 10 years back which uses makefiles

19:18

<deen> obviously

19:20

<fstd> wants autotools teeworlds

19:20

<fstd> </unpopular opinion>

19:22

<deen> I don't like cmake, but I liked autotools even less

<laxadedi> How to build sql release with cmake/make ?

19:35

<laxadedi> bam build is broken on my end for sql, dunno why and what changed, too lazy to look into that especially since bam is going to be removed

[ddnet/ddnet] Pull request opened: #839 fix bam windows build

<deen> laxadedi: cmake . -DMYSQL=ON

19:48

<laxa> btw, this should probably be on README

19:48

<deen> sure, add it

<laxa> rcon password config changed on ddnet ? I mean, the option to setup rcon password in config files ?

20:02

<deen> yes

20:03

<deen> python scripts/hash_passwords.py

20:03

<deen> create a separate account for each person

20:03

<deen> and write down those things for README, everything that's unclear

20:03

<laxa> yeah...

20:04

<deen> then we can just link other people to that instead of explaining again and again

20:04

<laxa> I'll probably stop hosting an empty ddnet server :(

20:04

<laxa> I don't wanna spend 30/60 minutes finding out what changed everytime I update my server sadly

20:05

<laxa> Don't know people actually having an instance of SQL ddnet running

20:08

<laxa> There is no way to have an rcon password oldschool way ?

yes in the autoexec

<laxa> "old way" is 'sv_rcon_password password'

20:10

<laxa> that doesn't seems to work anymore

login: empty

20:38

then password

20:38

no?

<laxa> there is not even a login prompt, just a password one

sv_rcon_password "mypass"

20:47

works for me

<laxa> ah I know why x)

<deen> laxa: so we have to stop development so that no one has to update anything? or what's the solution here?

21:15

<laxa> Well, I know you always try to "not break things" and try to keep ddnet as close as how teeworlds is

21:15

<laxa> I don't know the proper way beside having warnings when something change I guess

21:16

<laxa> but right now I dunno if it's my scripts/setup that makes it fail or not

21:17

<laxa> Like you use a software for years, you just update it from time to time, you don't take the time to read the changelog (that's my bad I guess), and something doesnt work anymore, it's kind of frustrating to spend time trying out to figure why.

21:19

<laxa> yeah, I know what changed

21:20

<laxa> teeworlds@laxadedi:~/Teeworlds/servers/ddnet$ ../binary/DDNet-Server -f ddnet.cfg

21:20

<laxa> [2017-08-07 23:20:06][console]: failed to open '../common.cfg'

21:20

<laxa> ddnet probably setting cwd as ../binary/ instead of the actual one

21:21

<laxa> that's why it's failing loading my common.cfg that holds the rcon_password

21:21

<deen> no, we forbid ..

21:21

<deen> security risk

21:22

<laxa> alright, I kind of disagress about that, it should be the admin/hoster responsibility

21:22

<deen> how so?

21:22

<laxa> well, if I fuck up my host/path/rights, then it's my own fault, not the software faults

21:23

<deen> meh, so I need to make sure that every ddnet server that we run runs as its own user or in a sandbox?

21:23

<deen> if you want to include .., you can add it as a path in storage.cfg

21:23

<laxa> Hum, I don't see how this is a security risk exactly

21:23

<laxa> because of admins ?

21:24

<deen> yes, ingame admin can use exec or change_map with any path

21:24

<laxa> I'll use absolute path, I guess it's overall better security, I agree

21:24

<laxa> Hum right, then okay, I see your point :)

21:24

<deen> exec /etc/passwd is fun too

21:24

<deen> i don't think ingame admins should have that kind of access by default

21:25

<deen> it's like a limited remote shell

21:25

<laxa> but they still can do exec /etc/passwd without ..

21:25

<deen> Especially since we host trashmap where everyone can be admin

21:25

<deen> we also forbid absolute paths

21:25

<laxa> so, exec does'nt work anymore ?

21:25

<deen> only paths listed in storage.cfg are allowed

21:26

<laxa> ah, nice

21:26

<deen> so if you want your admins to access /, then add_path / and use relative paths from there

21:27

<deen> accessing nuclear servers with our future tournament servers with change_map was also fun

21:27

<deen> tournament maps*

21:28

<deen> and of course going on test server, but execing the regular cfg to find out the mod password there

21:29

<laxa> ok fixed finally

21:29

<deen> next time you update and something doesn't work, check the log file

21:29

<deen> it should tell you where it failed

21:29

<laxa> I did, but later on

21:30

<laxa> Well, thanks for your time and sorry for being annoying :)

For fun, I made PHP Package to get informations from server. https://packagist.org/packages/savander/twservers Actually, It's possible to extend it to work with 64 clients, but first i need to figure out how to do it.
