Servers going haywire, 100% CPU, going down and rebooting, etc.

[ddnet/ddnet] Issue opened: #1161 Built-in IRC client

Split the main server list menu in half, where the bottom is the IRC chat. Taken from #1061

[quakenet] <Learath2> god damn kids :(

PathosEthosLogos

[ddnet/ddnet] Issue opened: #1162 Serverlist cache (a good solution when master server is down + generally faster reload)

From #1061 Serverlist cache, fast serverlist updating: I think this is potentially a big upgrade for populating the server list The master server recently went down. Server list caching would actually be a great solution for this!

[quakenet] <Learath2> @Pathos it's register-flood, can't really fix it with heinrich5991 being prolly asleep, ddnet servers should work fine through the ddnet tab though

PathosEthosLogos

[ddnet/ddnet] Issue opened: #1163 Recently visited server category/tab

From #1061 Maybe give option to sort the server list by recent visits to the server or an entirely new tab for "recently visited servers"

[ddnet/ddnet] Issue opened: #1164 Auto translator for chat

From #1061 Translator for chat: devs didn't seem to like Google API for translator, so maybe Moses can be an option -- https://www.quora.com/How-do-I-integrate-Moses-machine-translation-into-my-realtime-website/answer/Niko-Papula (there's link to Github under "Google Project Hosting")

PathosEthosLogos

[ddnet/ddnet] Issue opened: #1165 Encrypted chat: possible for /pm or /w?

From #1061 I just thought there could be some security applied to the chats. My guess is that the messages are sent as plain text. If I'm wrong, please close the thread.

[ddnet/ddnet] Issue opened: #1166 Skin fetcher

From #1061 Automatically get new skins, especially when other tees have an unrecognised skin by the local client, the local client can auto search or download etc.

01:50

PathosEthosLogos

[ddnet/ddnet] Issue opened: #1167 Coloured console text

From a reply in #1061 It would be really nice if this is applied! Distinguishing team colours, server message, etc. would be really helpful.

[ddnet/ddnet] Issue closed: #1061 AllTheHaxx has a few useful features (and it's open source)

whats with all the lag on ddnet usa

01:58

i checked status.ddnet.tw and it reports ~88kpkts/sec with almost no players so i guess ddos?

how can i turn off switche serverside by default again?

[quakenet] <Learath2> hmm, it seems master1.ddnet.tw is dosing usa...

02:37

[quakenet] <Learath2> master1.teeworlds.com*

how and why

[quakenet] <Learath2> I actually have no clue what is going on

lol

[quakenet] <Learath2> okay it's actually ddnet.tw syn flooding usa.ddnet.tw

03:00

[quakenet] <Learath2> now I'm very very confused

stop ddosing usa pls

[quakenet] <Learath2> why tcpdump would resolve ddnet.tw as master1.teeworlds.com is beyond me

03:02

[quakenet] <Learath2> well blocking ddnet.tw on usa.ddnet.tw makes everything much better :D

master1.teeworlds.com 164.132.193.153:8300

blocking both servers on eachother works, god knows why they were syn flooding eachother :/

[quakenet] <Learath2> if only I knew whether ddnet.tw can come back up without supervision, i'd just give it a restart

03:16

[quakenet] <Learath2> some kind of conn keep open attack with spoofing maybe, but I didn't know you could do those with tcp

03:19

[quakenet] <Learath2> 409008932 SYN cookies sent :/

What's syn flooding?

03:20

Oh nevermind, found syn cookies

[quakenet] <Learath2> why is it only me awake when weird shit happens?

03:25

[quakenet] <Learath2> especially weird shit that I have no idea how to fix

it is happening again

[quakenet] <Learath2> sadly this one is an actual syn flood

block tcp protocol

03:58

teeworlds use udp only

MySQL not xd

oh xd

03:59

but

03:59

well

[quakenet] <Learath2> tried sth, no idea if it works but oh well

04:08

[quakenet] <Learath2> well looks much better

cool

[10:58 PM] Finn: block tcp protocol [10:58 PM] Finn: teeworlds use udp only +1, also rate limit requests by ip

can anyone help me? i bought a new pc and nothing fucking works. cant get a picture. no usb works. (amd ryzon7. asus b350 plus. nvidia gforce gtx970. 2x 8gb ddr4 ram) heeeeeeeelp

turn power on

12:33

(for real tho "nothing works" doesnt mean anything. does it even boot, does the monitor detect it, what does it show etc)

it turns on but the monitor doesnt detect it. and my keyboard mouse controler etc. all usb doesnt turn on

you got scammed

i didnt buy it as a whole. i built it

that is what i thought, then rebuild it properly

12:48

search tutorials on youtube

12:49

if it doesn't work it is because you either don't know how to build it or you bought broken parts

does it happen that new parts are broken

maybe you forgot to connect a cable?

12:50

check your built

i checked for 1 hour and couldnt make anything out. the mainboard doesnt peep either which would give some info perhaps

no unless you got scammed or it got broken before you received it

12:52

where did you buy the parts?

12:53

ebay? xD

12:55

well anyway stop worrying maybe it is just something you didn't properly

mindfactory

you know that ryzen 2 requires the newest BIOS versions to work on [a, x, b]370 mainboards?

@Im 'corneum do you have multiple graphic outputs? have you tried all of them?

yes i did.

mh

i dont get a bios. or at least i cant see one

does the computer receive a signal, e.g. via hdmi so that it turns on (even if not displaying anything) if you're starting the computer?

are you german?

what do you mean

13:11

yes

https://www.gamestar.de/artikel/amd-ryzen-2-generation-bootprobleme-ohne-bios-update,3326095.html

AMD Ryzen 2. Generation - AMD verschickt Leih-CPUs für BIOS-Update

Aktuelle Mainboards mit Sockel AM4 können mit den neuen Ryzen-Prozessoren der 2000er-Serie verwendet werden, aber nur mit einem aktuellen BIOS.

13:11

that could theoretically be the problem

Does someone coincidentally has nvidia cudnn 7.1 for windows? Their download page is broken (edited)

13:21

He she it , das S muss mit

i do

13:36

dm me

13:36

[quakenet] <Learath2> do you have a case speaker?

13:36

[quakenet] <Learath2> without a case speaker it wouldn't beep anyways

be careful with running executables from random people on the internet

he must has anti virus, it is not a virus, he can confirm the anti virus doesn't complain

[quakenet] <Learath2> anti-viruses are not magic

just because an anti-virus doesn't detect a file, doesn't mean that it doesn't have malicious code

[quakenet] <Learath2> they can only identify viruses encountered and identified by researchers before

well i am not a virus creator xD

13:39

i was just going to troll him sending him a big picture

Hey Finn, would've sent you a dm by now, but i bypassed that login and got a direct link

13:51

"bypassed"

13:51

oh

@Im 'corneum how many cpu pins did you bend

i hope none. :P the cpu just fell into place

ok xD

@Learath2 you could take a look at https://github.com/ddnet/ddnet/pull/1157 again, if you want

@Äppelwoi 💛 🇩🇪😍 just to say, there's a way called AVE

18:19

Anti-Virus Evasion

18:20

it simply bypass AV

18:20

so yea, anti-virus aren't magic

anti virus evasion isn't magic too

it is

have you ever done AVE

sure

i think you are bluffing

nop

have you bypassed all anti virus?

sure I didn't made it by myself because I'm not a reverse engineer

18:24

but yea i've bypassed all av

when was that

18:24

2018?

reverse enginering to bypass an av?

around 6months ago

18:24

@Ryozuki depends yea xd

18:25

@Ryozuki some asm skillz could help for that

from my little knowledge the best you can do is make a fresh virus and it will work some days till it gets detected and blaclisted by avs

actually yea

you said AVE is magic, but then you admit you didn't made it yourself, and that you could require to know how to program in ASSEMBLY (edited)

an AVE isn't available all the time

18:26

it gets detected after a lot of time, but it works at the start

18:26

but when it doesn't get detected it is magic (edited)

yes but it requires a hacker to make the hard work

18:27

then it is not magic

sure, but you have some available payloads that does perfectly the job

well but xD

18:28

that sounds like "i am a script kiddie" no? xD

actually what i'm saying to you is that anti-virus won't detect all viruses

18:28

@Äppelwoi 💛 🇩🇪😍 well for that case sure i'm a script kiddie, ik what I'm doing, but Idk how basically it works

you know what you are doing but not how it works?

sure o: (edited)

ok then for you it is magic but for the people who create the AVEs it is not magic

thonkery

thats what i meant

hey it's magic for them too

18:29

they're happy to find out something like that

it is not magic if you need to spend a lot of hours finding a new way to bypass the anti virus

heh?

18:30

I say it's magic about the fact that it works

magic is something you can do instantly without hard work

depends of how you say it

anyway xD

18:32

can you infect linux?

nu

18:32

what do u mean lol

to create a virus for linux

you can make a linux virus too,

virus for linux? O:

i think they are called rootkits

does it exists? xD

yes

18:33

rootkits

yea, not a virus lol

kinda

well I was simply manipulating some backdoors

18:33

dats all

but you could create linux viruses, its just that the dumb users use linux

18:33

dont use*

18:33

linux

18:33

they use windows

18:33

xD

heh xd

you need root access to use rootkits

18:34

so

not at all

on windows there's some shits called UAC bypassing

rootkits are made to get root access

but sadly there's some programs to detect them

"Rootkit installation can be automated, or an attacker can install it after having obtained root or Administrator access."

18:35

well i guess both

18:35

but u could get the user to install a rootkit without knowing

18:36

e.g a custom repo with apt

if he doesn't have linux "skills" or a brain yea

as always you are better tricking the human than the machine

18:36

when hacking

the rootkit needs root access anyway

18:37

if it can't get root access it can't do anything

"The term rootkit or root kit originally referred to a maliciously modified set of administrative tools for a Unix-like operating system that granted "root" access.[3] If an intruder could replace the standard administrative tools on a system with a rootkit, the intruder could obtain root access over the system whilst simultaneously concealing these activities from the legitimate system administrator. "

stop wiki

those vulnerabilities get fixed very fast

i know

18:38

there are also tools to detect rootkits

it needs a vulnerability to get root access by itself

18:40

never had a rootkit infected my computer

cuz you never downloaded any shit or you always looked at the source of a script

well

but I think the funniest thing is backdoors

why would i run any script with root privilegies

cuz maybe some scripts needs it?

18:43

depends of what you're doing

the only thing that i run with sudo is apt xD

18:43

i think

18:44

the debian package manager

I hate sudo

why

idk, it isn't secure if you do not setup it

18:44

imagine you didn't configure it correctly

18:45

& I backdoor your machine with a simple payload injected in a program

18:45

& now imagine you're too stupid to run it as admin

18:46

I could create another account

18:46

I wouldn't even need to set it as root, simply the pw would be needed

18:47

then sudo & the curr pw of the created acc & I'm done

18:47

that's a bad example but imagine

okay

18:48

i understand

18:50

there are scripts online, with malicious code, they run a command, and they log your ip, so they can have access to your server

18:50

on pastebin

yea after i'll show you an example i've already saw

ok

just need to find it xd

ok xD

I think it got removed, but well it's easy to detect, but some noobs wouldn't see it

18:55

someone converted some shell code in hexa & converted it then in the code in plain text to execute it

i know, they encode the command with escape sequences i think

that's basic, rly basic, but it is a little example of shit malicious code

and they can do that in any language

18:57

but it wouldn't work on a personal computer i think

18:57

only on servers

18:57

i think

18:57

because how could they get access toyour computer remotely?

18:58

what if you have dynamic ip, and all ports closed (edited)

reverse tcp

what is that

it is the victim that initialize a connection

18:59

you can backdoor someone like that

oh (edited)

so, Victim - syn -> attacker

ok i get it

19:03

i think that people can do anything and they think they can't because they can't see a way to achieve what they want, but the way is front on them, they just can't see it in their minds

19:10

Image attachment

19:10

who can see it?

19:10

xD

I see it, but not when I open it

ok xD
