my server is solid also the minecraft server is empty but i can get a dump

ah I just realized the dump would contain sensible user data or can i use the berkley filter to just capture master traffic?

10:04

ah ye probably a destination filter

"bad udp cksum" thats probably already bad i guess

ah nvm the vanilla server also sends a bad checksum

10:20

@heinrich5991 do you have some tcpdumps I should run? So far I do not see a big difference to the vanilla server

That one is hard to reproduce. Tried on ddnet7 with 32 clients, high bandwidth, forced full snapshots (~0.6MBit/s per client), 32 rcon commands per packet, several thousand votes and simulated packet loss... but I'm still registered to the masterserver However, at the end the server crashed with errornous client id =\

errornous client id is such a classic biggest annoyance in 0.7 based servers

@redix put it in gdb if you can crash the server

Couldn't reproduce it yet. I'll try again later.

@ChillerDragon tcpdump -i <INTERFACE> -w dump.cap udp port 8303

and then send me the dump.cap

@heinrich5991 that would contain plaintext credentials

17:30

I mean I trust you and all and I would send you my passwords but its user data I do not feel comfortable sending that to anyone

Just capture masterserver traffic?

17:51

It's that part of the protocol failing to recover

yea thats what im asking what kind of filter do you think is good?

18:25

I used 'src port 7303 and dst master1.teeworlds.com or dst master2.teeworlds.com or dst master3.teeworlds.com'

dst port 8283 || src port 8283 || src port 8284 ?

18:37

I guess it's not the only server running there, so maybe && each case with the port of this specific server

there is only 1 src port

When the masterserver responds it'll have src port 8283 or 8284

ChillerDragon: would be nicer if it would be everything. you could not capture while you log into rcon

20:49

but it's fine that way too, I guess
