[2019-01-14 12:33:16][register]: WARNING: Master server is not responding, switching master im using latest version server and allowed udp port via ufw

yeah ur server will do that occasionally, if it just picks a different master and registers then there is no problem

11:37

11:38

this is my problem

what is the problem?

look players

did u refresh server browser

yes

are u a spectator or something

11:40

if ur in spec and u have the setting enabled to not count specs as players, thats the only thing i can think of

Image attachment

11:40

im in game

ive never seen that before thonkery

thonkery

i can give ip address if you want try

11:45

or you can see server name :d

i see ur server in the list with 3 players

11:49

but the players are not listed

11:49

youre probably being flooded with info requests which is why servers do this

11:49

Image attachment

11:50

u need to use a network monitoring program like tcpdump or something to find which ip is sending the flood so u can block it

11:50

or just block all udp packets with source port 80 because most flooders use this by default

11:53

i think they flood many servers at once because i see this type of traffic hitting my server as well

Image attachment

hm what is the point of these? :d

idk why people do it

12:06

but if u have a teeworlds server up and registerd to masters then it will probably be flooded by this type of traffic at least, if not actively targeted

so you are like being ddosed in a way?

sometimes i get ddos but no this does not count as a ddos

oh

its only ~1000 packets/sec, all from the same ip and blocked by like 3 different methods

Image attachment

lol yep

banhammer

12:14

theres ur problem

12:14

if u r on linux, do sudo iptables -A INPUT -p udp --sport 80 -j DROP

12:14

and if the flooding is not coming from default port 80

12:14

(which it is but) do sudo iptables -A INPUT -p udp -s 106.13.13.0/24 -j DROP

i blocked with ufw i guess

12:21

hm nice server is normal now

happy

will the next version be 11.8 or 11.7.3?^^

yeah

banhammer

Depends on whether we have any big changes

13:29

Bug fixes and small stuff -> 11.7.3, big changes -> 11.8

the ip that attacked u

some chinese ip address banned from my ssh connection :d (edited)

yeah well it's always like that

15:41

and it's funny to see logs of tested users

15:42

i hate those, with a port different than 22 you get way less of them

doesn't need change port

15:50

im gonna use port knocking

[ddnet/ddnet] Pull request opened: #1432 Merge BW support into IsDDNet

from now on Blockworlds can use this server message to tell the client not to use the DDRace (time) scoreboard. (https://github.com/ddnet/ddnet/pull/1387)

yeah they can always find which port it is, but by only allowing a group or a few users, only with keys and on a different port, you nearly never get any bots trying to connect, i have 0 of those in my logs for the last few days

just setup a honeypot on 22

16:07

KirbyJam

just setup a setup

and change real ssh to a high port

Honey

@Ryozuki no

17:34

the best would be to redirect 22 port to the current IP who asked to connect on it :v)

17:34

Cuz CONNECTING ON HIS OWN MACHINE IS COOL

if you use ssh keys only (PasswordAuthentication no), it is infeasible for an attacker to get into your system. disable logging of failed attempts and the problem is gone

its always nice to collect data

17:44

about what they try to do

in a network sure but i wouldn't do that on the same server, just because another open port is another possible factor

@heinrich5991 basically if you disable Password auth you have to disable PAM also

18:07

well basically

true. it's disabled by default, but some distros might enable it for you

@Ryozuki why store gigabytes of their attempts? at some point you have to prune them anyway

@deen just create those accounts with a restricted shell or just with /bin/false :v)

@heinrich5991 is teehistorian causing demos to be removed? I see lots of " failed to remove: demos/_8324_0_tmp.demo " on official servers during startup

Delete teehistorian feelsgoodman

feelsgoodman

feelsgoodman

feelsgoodman

feelsgoodman

@deen teehistorian code only ever writes data

ok, strange

and it shouldn't mess with demos at all

oh, i'M seeing it locally too

21:04

thought it's only on official servers

21:04

then I'll take a look

ah, these are new error messages

yep

21:04

before the if was the wrong way around

21:04

so it only printed an error when the removal was successful

teeworlds code always looks so scary. thanks for at least adding logging for these filesystem errors

Ah, I see the code
