[serene tide]

You should ask this in #paper-help assuming you're running Paper

[wet heart]

whoops sorry

[candid narwhal]

i sometimes have an issue:

[05:43:13] [Netty Worker IO Thread #11/INFO]: [sesposesso] disconnected with: ReadTimeoutException : null

Im using latest version of waterfall

[marble kelp]

network issue

[wet flame]

THis message appears when you do /server toast but the server has /whitelist on

can i change it somehow?

[wet flame]

its there when the server is offline too

[reef fulcrum]

That means that something tried to connect them to the server that they're already on

best guess would be replicate without plugins

[wet flame]

But i want to change that message

[reef fulcrum]

Yes, copy the messages file out of the jar and throw it in the server folder

But, if a plugin is causing that, that's a bug

[azure dagger]

So there is a really bad bungeecord exploit

Basically someone came onto my server and ran commands through my account even though they didn't have my account, and they were able to pull everyones ip and everything

So they were able to op themselves on any of my servers

[scenic pebble]

Sounds like you exposed your backend.

[azure dagger]

Yeah but how?

[scenic pebble]

Well, if your backend servers can be pinged from the internet, then you have not secured them properly.

[azure dagger]

I was asking them about it on discord, because I wanted to know what they did, and they said they just used bungee exploits, and almost all servers have this exploit

[scenic pebble]

I mean if there was an exploit on this scale, and "almost all have them", that would insinuate that it's existed for awhile. I would've thought it'd be reported by now, no?

[azure dagger]

Yeah they said it has been around for awhile

And now I'm reporting it also want help to secure my bungee more

[reef fulcrum]

It's not an exploit, it's just blatent misconfiguration

[azure dagger]

So how would I fix it?

[reef fulcrum]

You need to configure your servers so they're not accessible from the network

i.e. local routing, firewall, bungeeguard

[azure dagger]

So why have they been able to do it on alot of servers

[reef fulcrum]

Because people don't read the bungee install instructions

[azure dagger]

Hmm so is there not away to fix it in the code?

[proper prawn]

why you need to fix the code when you need to fix the config

its a config issue, not a bug in the code

[reef fulcrum]

Well, that's what bungeeguard does, it does it at code level, but, not ideal due to how bungee works, velocity has a better option for it, but, that only works with the modern forwarding protocol they have, which I was kinda debating on bringing to waterfall, but they way I wanna do it requires touching some classes I don't like

[azure dagger]

Oh

[reef fulcrum]

Oh, wait, no, bungeeguard does it as right as possible with bungees forwarding stuff

I was debating on adding that to waterfall before I noticed there was a plugin for it

[azure dagger]

Yeah

https://github.com/lucko/BungeeGuard

That one?

[reef fulcrum]

yup

[azure dagger]

And it goes on the bungee sere

Sever

Nvm that was a really dumb question

[reef fulcrum]

it goes on the proxy and the servers

[azure dagger]

Yeah I read it at the bottom thankyou

It says 1.15 is the latest does it work for 1.16.3?

[reef fulcrum]

yes

[azure dagger]

okay thankyou

[reef fulcrum]

1. wrong channel

2. Read the mojang issues and the issues on our tracker, there's already info about it

[novel kindle]

oh sorry

[odd hatch]

Are you running the latest version of Floodgate?

Their plugins line 85 is already doing weird stuff.

(For the curious lurkers: https://github.com/GeyserMC/Floodgate/blob/development/bungee/src/main/java/org/geysermc/floodgate/BungeePlugin.java#L85)

[wet flame]

zzzcat

its not plugin

its bungee

default message

i cant find how to change it

[surreal bison]

Hey i have read in other discord waterfall Support mods? So its possible my Main Server is on paper and my second on sponge/forge for pixelmon mod?

[royal hawk]

As long as your forge server is on 1.7-1.12.2 and is running in a forwarding-supported-mode (with sponge configured correctly for proxy use) and your lobby supports your forge version (or you use forced hosts) then yes. That will work

@wet flame if you absolutely need to change this message: edit https://github.com/SpigotMC/BungeeCord/blob/master/proxy/src/main/resources/messages.properties in waterfall/travertine/bungeecord and compile it yourself

[wet flame]

But its broken, it doesnt display right messages

always already connected to the server

even when banned, not whitelisted or server offline

[royal hawk]

That happens when the server you’re trying to connect to never correctly disconnects the player or a plugin on your proxy never correctly acknowledges a disconnect

It should say some like: Error connecting to server X: The ban hammer has spoken!

If that doesn’t happen then you have a faulty plugin or setup

From the looks of things it’s an issue with the plugins on your proxy

Try replicating it without any plugins on the proxy server

[night wigeon]

Hello, how do i change the suppported versions? Like how should i write it if i want to support from 1.18.x to 1.16.3?

(In the waterfall.yml)

[proper prawn]

1.18.x
are you from the future?
Waterfall supports 1.8-1.16.3
Travertine supports 1.7.10-1.16.3

[night wigeon]

Srry, i meant 1.8

[proper prawn]

if you want to change that thing in the server list, you need a plugin for that afaik

[night wigeon]

I got ViaVersion, i just want to change it in the waterfall.yml, but i don't know what's the syntax

To the line 6:

game_version: '1.16.3'

Nvm, i ended up finding it ^^

[cold haven]

this might be a bit off topic but im running waterfall on pterodactyl panel

but for some reason it keeps setting my server's ip to this

172.18.0.1

[marble kelp]

that's the local IP of the docker

there is probably a configuration somewhere in the panel for the addresses of the servers

[tidal musk]

@wet flame if you absolutely need to change this message: edit https://github.com/SpigotMC/BungeeCord/blob/master/proxy/src/main/resources/messages.properties in waterfall/travertine/bungeecord and compile it yourself
@royal hawk bungeecord (and its forks) can read messages.properties from cwd as well

so you don't need to compile / replace messages in the jar

[reef fulcrum]

We've gone over this multiple times

You literally just need to pull out the file and shove it in the folder where your proxy is running

You can grab the file from there, but, you'll probably be missing a translation key or two potentially from what I recall

[cold haven]

@reef fulcrum mind pinning that message ?

[cold haven]

ty

[delicate phoenix]

Is there a way to make a timings from waterfall?

I set 1GB for the proxy, but it seems like it's taking 1,6Gb, and i'm intrested why.

[proper prawn]

off-heap

[reef fulcrum]

no, timings is useless for the proxy, it doesn't have a tick loop

.heap

[marble kelp]

-Xmx controls the amount of heap memory assigned to the JVM, this does not include memory used for java itself and the native memory used by java itself, as well as other libraries such as netty (for networking) and SQLite.

[delicate phoenix]

521MB ram for the -xmx value sould be able to handle 75 players?

[proper prawn]

i highly doubt that

[delicate phoenix]

How many sould I allow for that amount of people?

[marble kelp]

512MB should easily be able to handle 100 players

or even more

[heavy zinc]

what are the permissions for waterfall? i am having an issues using the /server command. says i do not have permission to use that.

[unreal stag]

bungeecord.command.server

[heavy zinc]

Thanks!

[upper zinc]

Hello. If I turn my server into a bungee server, do I need a lobby? Or can I just have a portal in my survival world lead to the other world?

Also could I have one IP and have the server redirect them to whichever server they logged off at?

[proper prawn]

Or can I just have a portal in my survival world lead to the other world?
you can do that

or you can give access to /server

[upper zinc]

?

[proper prawn]

Also could I have one IP and have the server redirect them to whichever server they logged off at?
it should forward them to last server they were on unless you have forced_default_server on

[upper zinc]

What I want is two different types of worlds that you can travel between with a portal. No commands for them. I also want is them still have the ip with no port at the end, and it just places them in whichever world they last logged off. So it basically seems like another dimension, but obv inventory don’t going with. 

I don’t want any teleporting on the server though commands. Only through portals.

[proper prawn]

I also want is them still have the ip with no port at the end
Your proxy port should be 25565 then

and it just places them in whichever world they last logged off
Default behavior

[upper zinc]

For all servers? I’ve never done bungee, but saw a video ages ago for it.

[reef fulcrum]

You'd need a plugin for the portals, e.g. bungeeportals

[upper zinc]

That’s fine. I just want to make sure this is all possible and not overly difficult.

Before I try any of it.

[meager citrus]

Hi guys, what's optional timeout: 90000 in config.yml?

I have problem that when I decrease it, then when I use autoreconnect plugin i'm getting this

[marble kelp]

that means that the server was not reachable, changing the timeout wont really help there. you will have to fix your network issues

[meager citrus]

but when I change it, it works

when I have for ex. 90, it works

but 20 not :/

and when I'm not using autoreconnect plugin, it normally works too, just when using autoreconnect players aren't connected and they're getting this error

And what exactly do you mean by network issues?

[marble kelp]

talk to the author of that plugin then

[meager citrus]

I tried, he also think that I should have lower value of timeout, but when I decrease it, then there's this exception as I mentioned

and I'm still having problem with "Already connected to the proxy", which appears even when I tried remove all plugins from sub servers and proxy

[mossy spindle]

Is here a plugin that sends you to an AFK server

and when you move it returns you to the server

?

I tried a plugin called: Lobby AFK [AFK Server for Networks]

But it gives me an error

https://pastebin.pl/view/1593400c

[severe badger]

It's not a bungee plugin

[mossy spindle]

it's for spigot?

[severe badger]

yes

[mossy spindle]

oh

[severe badger]

apparently

[mossy spindle]

and there is any plugin

for bungee

because I have sponge servers

mayb this one? https://www.spigotmc.org/resources/limbo-standalone-server-lightweight-solution-for-afk-or-waiting-rooms-in-your-server-network.82468/

oh but its for 1.16

[proper prawn]

Standalone Server

oh but its for 1.16
you aren't sane and you dont use a supported version?

[severe badger]

If you are using sponge, you could ask in the sponge community for a plugin/mod

[marble kelp]

you cannot (easily and sanely) detect afk state on the proxy, lol

[mossy spindle]

Oh ok thanks

[cursive flicker]

@mossy spindle plugin on each server that detects AFK and informs the Proxy Plugin of the AFK player, the Proxy Plugin then decides what to do based on config.

Not sure if you have any development knowledge but that theoretically would work.

[mossy spindle]

I found a plugin

that works

on spigot

but I have servers with sponge

so it doesn't work

[cursive flicker]

Yeah that will always be complicated, most plugins only support one not the other

[cursive flicker]

I randomly had a likely DNS issue with my waterfall.. I'm using docker overlay2 networking. Basically one server name was resolving to another server in my network until I restarted waterfall. Not sure if anyone has experienced that before?

[spiral merlin]

hey I was wondering if waterfall could be used for handling connections that go to a single server? as a reverse proxy thing

[royal hawk]

You can do that

[sudden oasis]

I'm experiencing an issue with an own fork of waterfall where, sometimes, disconnected players remain online until the read timeout kicks in. Is this an existing issue in waterfall/bungee or is it something I've done? I've been looking at my changes but can't guess what it could be

[twin solstice]

have had this issue various times before

[twin solstice]

https://github.com/SpigotMC/BungeeCord/issues/2371 probably related

[fickle flare]

is there a reason that overflow in packet detected! Cannot receive string longer than Short.MAX_VALUE (got 34711 characters) this is a thing?

only happens after trying to send a large msg through a plugin *

[green palm]

well, there you have the issue

[fickle flare]

this isn't an issue however without a proxy

so is there a reason this limit is there?

for context im trying to send this https://cdn.discordapp.com/attachments/741875845089722499/765910976541229116/unknown.png

pls dont ask

[marble kelp]

component message json length have a limit, use multiple lines

[fickle flare]

why is this limit bungee / waterfall specific though?

[marble kelp]

because the proxy will try to handle the packet, and if its invalid it can't handle it

[fickle flare]

so why does the proxy have it as invalid

since without the proxy it would work and the client can receive and handle it

[marble kelp]

because there is a max length that the json string of the component can have

and I assume if deserializing the json to a component and serializing it into a json again is above it then you will see this error

but the limit in Bungee might actually be wrong, it looks like the limit for UTF8 strings is (max short) * 4 as each utf8 character is 4 bytes?

see https://wiki.vg/Protocol#Data_types

might depend on the version though, not sure

[fickle flare]

yeah sorry i dont understand technical talk that well haha, i just wondered if there was a reason why bungee / waterfall differed from a spigot / paper server

just wanted a reason to why my thingy wasnt working as apposed to giving up for an unknown reason

[marble kelp]

I would say it's a bug

or legacy compatibility but I doubt that Mojang changed that part

[royal hawk]

Phoenix it is a bug but not a fixable one

In newer versions the limit is larger

In older it’s not

So for consistency it’s set to the old limit

[marble kelp]

I see

pretty pointless for people not having any old version support, lol

[royal hawk]

Yea I mean

Send as many messages as you need to get the message across is my idea

But I mean

[unreal stag]

just use Velocity

problem solved

[fickle flare]

how are plugins on velocity

thats something that i've never really looked into as i assumed no devs worked on stuff for it

[unreal stag]

There are in fact plugins for Velocity, at the very least you have the basic ones like NuVotifier, LuckPerms, ...

https://forums.velocitypowered.com/c/plugins/plugin-releases/6

[mint terrace]

stupid question, but do plugins need to specifically support velocity in order to work on the server?

or is it a "give it a shot and pray" typa deal

[marble kelp]

of course they need to support it, its a completely different plugin api

velocity has nothing to do with bungee/waterfall beyond providing roughly the same function which is proxying requests to multiple servers and allowing switching between them

[mint terrace]

thats why i ask, wasnt sure the purpose velocity served overall. wasnt sure if it was like where bukkit plugins work on spigot which work on paper, etc

[marble kelp]

does velocity basically decide that based on the client/server version or how does it handle the different string lengths?

[unreal stag]

Velocity only reads a select number of packets, so for the most part many packets go through unaltered.

[fickle flare]

rip bungee

[shadow trout]

Are OVH cloud vps any good for a couple of istances of waterfall + antibot deluxe?

[reef fulcrum]

Yes

[shadow trout]

What do you recommend? i know that bungeecord doesn't require a lot of ram but in my gaming-serv vps the cpu goes around 10-40% with just the staff online (10 players). When i will open i will have from 100 to 150 players online so this 2 core vps will just go 100% and explode. Maybe 4 vcores are enough for an instance of waterfall?

[reef fulcrum]

CPU usage is a bad metric for performance, not to mention you've got the JVM itself doing stuff, it's hard to say

[meager citrus]

Hi, is there command for plugin list?

[reef fulcrum]

no

[meager citrus]

and can't be? :/

[reef fulcrum]

Somebody could easily program one

Just, there has never been a demand for it

[meager citrus]

and it should be module or plugin?

[reef fulcrum]

Not like checking your plugins folder or logs is hard

what?

[meager citrus]

yeah but when someone is asking for plugin list

you have to write everything by plugin folder

[reef fulcrum]

If it was built in to the proxy, it would be a module, if it was 3rd party, it would generally be a plugin

[meager citrus]

normally printing list of plugins will be easier

mhm, I'm surprised that there isn't already plugin for it

[reef fulcrum]

There is literally 0 difference between modules and plugins

Because there isn't a demand for it

[meager citrus]

For ex. when I should somewhere put my list of plugins, i'd rather make screenshot 😅

[reef fulcrum]

1. You can literally screenshot the servers files

[meager citrus]

yeah that's what I'm doing

[reef fulcrum]

2. I literally refuse to provide support for people who screenshot that stuff from their chat

[meager citrus]

When it's possible I copy it normally from console, but on proxy I have to screenshot it

[reef fulcrum]

"screenshot of folder" != "screenshot of chat"

[shadow trout]

CPU usage is a bad metric for performance, not to mention you've got the JVM itself doing stuff, it's hard to say
@reef fulcrum Okay thanks i will take an option and just guess

[spiral merlin]

is there like a way to stop pterodactyl panel recongizing the end command as a crash and automatically rebooting the proxy?

[woven stone]

How cna I disable the /server command? It's not in the perms and in the config perms.

[stone marten]

I pretty much know what everyone here is going to say
But be honest which is better
BungeeCord or Waterfall
???

[severe badger]

You are asking this in the channel

[stone marten]

ok then waterfall it is

[spiral merlin]

yessir

[royal hawk]

@woven stone negate the bungeecord.command.server permission

[woven stone]

Doesn't work

[young rampart]

That's the permission for that command from bungeecord, if that doesn't work maybe another plugin overwrites that command

[royal hawk]

^

[tidal musk]

Anyone know why waterfall keeps a player still in the proxy even when they just hitted the disconnect button

It happens commonly atm.

[severe badger]

.paste

[delicate jewel]

https://my.gaagjescraft.net/paste?name=E5YSOBWP/raw

what is error👆

[tidal musk]

https://github.com/PaperMC/Waterfall/issues/530

Can't there be a solution to fix it?

I don't think it's a Minecraft problem, because using other forks (which I don't want to do) this problem doesn't exist

@unique linden?

[unique linden]

Is there a steak involved? otherwise im not much help

[reef fulcrum]

It's a property file

property files don't support multi line messages

Also,

Can literally not be fixed on the proxy, this is a client issue

If you know a fix for the issue that we don't, feel free to PR one or get somebody to PR one, but, it's a client issue

[mental charm]

I forget how to set a fallback server, I've tried putting my lobby under priorities, can someone point me to some docs?

[marble kelp]

you set the priorities list

[mental charm]

It doesn't seem to kick to the lobby on restats for some reason?

[bold swan]

Need a plugin for that

[mental charm]

any recommendations?

[bold swan]

Phoenix made this one, should work and be lightweight

[mental charm]

tyvm, I'll check it out

[mental charm]

Thanks thesciencewalrus works perfectly, no config needed 😄

[solar lark]

With update to 1.16.3 players in spectator mode can't move through blocks any more. Is this a known issue? I doubt it, but I can't find anything about. It works on single paper server (without any plugins and with default config) but doesn't work when I just put that server behind latest waterfall proxy.
Only similar issue I found is very old (but exatly same behaviour): https://hub.spigotmc.org/jira/browse/SPIGOT-1629

[delicate jewel]

what is this error: link:https://justpaste.it/6rozw

[marble kelp]

isue with metadata rewriting, you could try disabling it

[meager citrus]

Hi, is there any demand on using Travertine instead of waterfall?

[royal hawk]

@solar lark this happens when:

• You, yourself aren’t on the tablist
• Your Server isn’t addressing you in the tablist by the correct UUID

In the case of bungeecord, you need to disable tablist rewriting.
You should also check to see if you set up bungeecord forwarding correctly

Stupid mojang code checks the hitbox of things using the tablist gamemode entry for yourself instead of the gamestate or your gamemode

@meager citrus you’d use it if you needed 1.7 support

@delicate jewel disable entity meta rewriting, that looks like a forge/ custom server error

Honestly idk why md still enforces rewriting

[meager citrus]

and why 1.7 isn't built in waterfall?

[solar lark]

Ah, thanks a lot.

[royal hawk]

@meager citrus cause few people still want it and way more than that want it gone? Minecraft 1.7.10 is 6 years, 3 months, and 20 days old today.
It’s dead Jim.

[distant crystal]

what is waterfall?

[reef fulcrum]

fork of bungeecord

[distant crystal]

ok

[tidal musk]

What's the recommended amount of RAM Waterfall needs ? I know for Paper it's around 6GB-10GB but i'm not sure if the numbers are the same..

[reef fulcrum]

minimum is generally like 512MB if you wanna ensure it has enough, +256mb per 100 players or so

[tidal musk]

Perfect, thx ! 🙂

[hard jasper]

Is there a way i can make it so when my proxy goes down it doesn't kick the servers from the server it connects to ?
not talking about when the acctual server is down or restarting just talking about when the proxy crashes (from bot attacks) so it just blocks new players from connecting rather then kicking all the current ones ?

[strange brook]

how exactly do you think proxies work

like, where do you suggest the traffic goes

that's basically like asking if you can connect to the internet when your router is off

[hard jasper]

but can they just stay on the server if they've already connected?

[proper prawn]

all the traffic goes thru the proxy

[strange brook]

sure, why can't you just keep watching that twitch stream after turning off your router

[proper prawn]

if the proxy is down, no traffic can reach the server

[strange brook]

the client is never connected to the server, it's connected to the proxy

[hard jasper]

ok thanks for the help

[nimble zenith]

When I join the server, I want it to send me to the lobby, but it sends me to the last server I played on. What should I do? Can you @mention me?

[proper prawn]

@nimble zenith force_default_server

[nimble zenith]

ok thanks

[tidal musk]

Anyone know why waterfall keeps a player still in the proxy even when they just hitted the disconnect button
@tidal musk anyone know answer?

[reef fulcrum]

No

If somebody had an answer, they'd of given you it

Outside of that, "replicate without plugins"

[tidal musk]

Well it was been a few days ago, could be not readed.

Yes, done that

[reef fulcrum]

If you can reproduce it without plugins, create an issue report, but, erm; In general, unless there is some way to reproduce it consistently in all setups, stuff like that is generally just gonna stick around as there's like, 1 or 2 people who have that issue out of the hundreds of proxy instances running, so it's very 🤷‍♂️

[tidal musk]

Well, i've tested it on different networks just to see if it happens. It happens a lot.

But i guess im just the one that notices this.

[reef fulcrum]

We need means to reproduce it consistently, and, we basically don't have that

[tidal musk]

Well, it happens when you just hit the disconnect button, sometimes it disconnects you from proxy fine. but if you join then again and leave you see you stay online for like 1/2 minutes.

[reef fulcrum]

Never reproduced that one personally

[tidal musk]

Idk, maybe my bungee config is wrong

its pretty much default

[reef fulcrum]

and it's impossible for stick in a dangled state for that long as the read timeout handlers would pick up on the dead connection

[tidal musk]

Also tried to look for a wiki about what all options does since there are new options in it. But cannot find really info about those settings

[reef fulcrum]

Afaik, there are cases where the client does screw up disconnecting, but that's not something we can deal with as it still leaves an open connection

Do you have mods installed? I know it's a vanilla client issue, but, there are instances of mods making it more likely to happen

[tidal musk]

No, i do not have mods.

[reef fulcrum]

Fun joyous issues of people being connected to two servers at once

[tidal musk]

Its just pure vanilla atm

https://paste.helpch.at/icurapomig.makefile

this is how the config look like

[reef fulcrum]

Does closing your client fully kill the connection?

[tidal musk]

after a few min

1/2 min

but it also happens when just hitting the disconnect button. and also my manager & mods had the same issue, i asked them to test.

timeout: 30000

what is this option?

[reef fulcrum]

It's the idle handler timeout

[tidal musk]

Like i know it manages connections

[reef fulcrum]

Which is covered in the docs you said you read...

[tidal musk]

Yea, i see.

[reef fulcrum]

Basically, if netty doesn't read a packet in that long, it will close the connection

if the connection is still open, idk what to tell you

[tidal musk]

when you get kicked after 1/2 min this is the msg in console ReadTimeoutException : null

[reef fulcrum]

So, yea, the connection wasn't closed properly

That's the idle handler I keep talking about

[tidal musk]

that's odd.

[surreal bison]

Hey i have a waterfall Server With 2 1.16.3 Servers and one 1.12. 2 spongeforge how i make it worked With mods?

[royal hawk]

Set up forwarding according to the sponge docs and the paper docs

[deep cradle]

Hello, I have a question can you use waterfall for 1.7.10 to 1.16.3?

[reef fulcrum]

no, you'd need travertine for that

[deep cradle]

Thx

[reef fulcrum]

I have a plugin on the forums, beyond that, scream at plugin devs to fix their stuff so perms work properly

yes

[royal hawk]

[tidal musk]

bruh

[narrow light]

Anyone know why my server icon has shrunk with the latest waterfall?

i think it might be related to this bug but i dont know how to fix it in waterfall https://bugs.mojang.com/browse/MC-190199

[delicate phoenix]

I don't think you can fix it, it's a client side vanilla bug.

Try restarting your game.

[narrow light]

oh intersting, lemme try that

okay yeath that fixed it, thanks

[delicate phoenix]

👍

[narrow light]

okay i need to pass out, y'all cool

[ripe stag]

hi i wanted to know, can you set up waterfall with a forge server and a paper server?

ive done it but whe i try to join the forge server it tells me i need forge even when i have it installed

[reef fulcrum]

It basically relies on the first server you connect to being able to do the forge handshake

It's a limitation of how forge works, and forge doesn't work on newer versions due to some changes which basically make server switching with forge unviable even more

[ripe stag]

oh

[reef fulcrum]

It works, but, we can only garauntee so much, and mods are also generally another fun aspect

[ripe stag]

the problem im having is connecting to it

is there an option to toggle somewhere?

[reef fulcrum]

if you was to set the forge server to the default server, it wouldprobably let you join

if you used bungee, there is the forge option in the config file, beyond that, no

[ripe stag]

imma check if i have that on real quick

i think i dont

weird, its on

i do have a hub before connecting to the server though

might be that

[twilit oxide]

Hi, is it possible to tell from the latest.log if the waterfall setup fails to hook in with a specific server?

[reef fulcrum]

easily and sanely? probably not; use a plugin 🤷‍♂️

[twilit oxide]

haha ok

[unreal stag]

nobody's going to give you support for that

[solar flower]

Maybe I'm stupid ... but I can't find some documentation about installing the waterfall server. As I understand, waterfall is the better version from BungeeCord? What is the installation of the "waterfall lobby"? Just download waterfall.jar and start it ?

[severe badger]

It's a drop in replacement for Bungeecord

Like any proxy, it doesn't care about your servers, whether they are a lobby or whatnot

[solar flower]

So how should I install it? Install Bungeecord first and then?

[severe badger]

Check the docs if you don't know how to get started

[solar flower]

Which docs lol

I didn't find the docs. In github is only written "just download the jar here"

[severe badger]

https://paper.readthedocs.io/en/latest/waterfall/getting-started.html

[solar flower]

I've read the docs. Can I ask here either if I have more questions?

[young rampart]

Sure

[solar flower]

I'm not sure, if I unterstand.

At Bungeecord: I put the bungeecord.jar and start it, the lobby-world will be created automatically (at my farming server config I say port is 25568) and in the bungeecord config i say here is your game server with the port 25568. The bungeecord server himself has the 25565 (default port to join on the bungeecord /lobby server). As I connected to the bc server, fine, i can themeless teleport to the other sever.

At Waterfall: What? When I start the Waterfall.jar, the waterfall server create no world or something else. The waterfall.jar start with port 25577. Is the waterfall.jar not my "lobby server" as like bungeecord?

I know run as root is bad, it's here just for testing.

[bold parcel]

waterfall/bungeecord both aren't a server

they're a proxy

your lobby server is your lobby server

you tell waterfall where your lobby server is (what port), and it'll send players there

waterfull is literally a dropin replacement for bungeecord - if you remove bungeecord jar, and put in waterfall jar, your same setup will work

[solar flower]

Okay

Thanks

[solar flower]

Works ... Thanks for your help

Hmm, is there a way to make a failover proxy in waterfall? So, when I have to restart the first proxy that the second proxy take over and the player are not disconnected?

[marble kelp]

you basically can't

[solar flower]

hmm kay

[small pike]

I would like to create a "hidden" server as apart of my waterfall network that completely hides its players
making a server restricted almost works fully, except that the player count still increases and glist shows the total player count
maybe there is a plugin that can do this for me?

oh maybe premium vanish

[marble kelp]

should be a pretty simple plugin tbh

only has to remove the players on certain servers from the ping count and replace the list command

(although shouldn't glist already hide servers that a player doesn't have access to?)

[small pike]

you would think so

well

it does.

but it lets everyone see the true 'total' player count

[marble kelp]

odd

might want to open an issue about that lol

[small pike]

maybe its configurable and I simply don't know enough

ill try premium vanish

[marble kelp]

don't think so

[small pike]

otherwise I might resort to making that plugin

[proper prawn]

use a firewall to block connections from the query port

[royal hawk]

Someone is DDoSing your proxy

But yea

Do that

[proper prawn]

afaik you can spoof the ip it shows

[proper prawn]

change the query port and block it in the firewall

can i choose what port to use?
yes

if i just use that on all my papermc servers and then waterfall
all connections go thru the proxy, so just block it on the proxy and it should deny it

[bold parcel]

yes

[opaque valley]

is there a wiki or tut out there on how to set up waterfall? First time, setting up a bungeecord network, and want to make sure things are done right

[reef fulcrum]

Follow the bungee install guide, it's basically just a case of configuring the servers in the proxy config and enabling bungee/disabling online mode on the backend servers

[muted olive]

Anyone know why I can use my bungee and go to other server but the user cannot he gets disconnected from the host when trying to connect to server but the lobby works. Lobby is 1.15 and server is 1.16? Is it a version conflict?

[marble kelp]

you can only join a server which matches the client's version unless you have some plugins installed to allow other versions to join

[muted olive]

Yeah I have viaversion

It allows me to join the 1.15 from 1.16 client but not user quite strange. I am going to upgrade everything see if that solves it

[bold parcel]

if the player is 1.15 and tries to connect to 1.16, it won't work

you'll need viabackwards

but at that point, why not just update to 1.16 :p

[muted olive]

Don't think they're 1.15

They are 1.16 I think

[reef fulcrum]

I mean, if it continues running, yes

god knows wtf is up with your machines network interfaces

Well, it's tryna get the network adaptor associated with the loopback IP

It's failing to find that interface

Basic networking

each machine has a network interface, the loopback adaptor, or, lo0, generally

Your machine is having some oddball issues finding that

either DNS is busted or that interface is busted

🤷‍♂️

You'd need to work out what the exact issue is

aka: you started screwing with stuff you don't understand and are now having issues from it

Best advice I can give you is check that you can ping "localhost", and check that the lo0 adaper actually exists

Well, yea, it just carries on without that info, it's safe, it's just generally a sign that you have deeper issues

use ping4, i think it was

God knows

the logging framework wants that interface for the mac address

Basically, you got two options, ignore it, or learn how to fix it

Those aren't the type of issues we provide support for here, far too much potential for stuff breaking further which we defo don't wanna deal with

Because they use an outdated logging framework

[tidal musk]

hey

what are the benefits of using waterfall over the canonical bungeecord?

can this waterfall system handle a network with 50,000 players?

[reef fulcrum]

performance improvements and exploit harderning

50k players on a single instance, no, you'd bottle the NIC before you even got close to that anyways

[unreal stag]

scratch that, you'd bottleneck the CPU well before then

[languid river]

Technically possible, as if each player uses 1 megabit of internet, you still have room left over in a dual 40-gigabit NIC.

Is there a proxy setup?

If you have a proxy that can happen, it's actually why I can't use Nginx with Geyser

Nginx

There's your problem

[reef fulcrum]

Don't use nginx for this stuff

1. Unless you configure it properly, e.g. you're not making it think it's tryna forward HTTP, it /should/ work

2. The nature of a proxy means that you're going to lose source IPs

Depends on how it's blowing up, can't really say without logs, etc

Also, I have no idea how to do 1, never used it for such

.g nginx tcp proxy

[marble kelp]

(DiscordBot) https://docs.nginx.com/nginx/admin-guide/load-balancer/tcp-udp-load-balancer/ -- TCP and UDP Load Balancing - NGINX Docs: "Configuring Reverse Proxy. First, you will need to configure reverse proxy so that NGINX Plus or NGINX Open Source can forward TCP connections or..."

[reef fulcrum]

But, once again, that's heavily useless, you're just gonna break IPs, etc

Really, if you need a proxy, use waterfall or something, that way you'll keep UUIDs/IPs

Because the connection is proxied

It's not a tunnel, the proxy just creates a brand new connection from its own IP

So, why are you tryna throw extra crud in front of that?

wait, I have no idea where the source of the nginx convo game from, god knows

show logs.

[tidal musk]

Is there a way to remove those? lol

[bold swan]

Pretty sure you just have to change log_pings to false in the config.yml

[tidal musk]

okay

[royal hawk]

@lilac moss wrong channel #paper-help

@tidal musk tell us a lot more about your setup. What interface are you binding? You have a Waterfall proxy connected to nginx? What are your settings for that?

the InitialHandler is run pre-login afaik

so it can be even a problem with backroute

[reef fulcrum]

Hamcio, we cannot help you with the information or lackthereof that you've provided

show logs.
@reef fulcrum

Yes, and the servers too

.paste

[marble kelp]

Please paste large logs to a pastebin: https://paste.gg

[reef fulcrum]

walks out

I'm asking for a copy of the logs

Not a fucking narrative of them

[delicate phoenix]

???

[reef fulcrum]

Then you're on your own

[severe badger]

lmao

[reef fulcrum]

Don't ping me

[reef fulcrum]

I don't owe you any support, and I've made it clear I'm not really interested in helping you; I've also asked for you to provide information multiple times, upon which you finally get the hint that you should have provided that info after I tell you you're on your own, I don't accept DMs, and my head already hurts, so I further have no interest in messing around to accept DMs from you

[reef fulcrum]

[3:55 AM] zzzCat: show logs.

[11:55 AM] hamcio: logs from proxy?
[11:55 AM] hamcio: waterfall?
[11:55 AM] zzzCat: Yes, and the servers too

Once again, I don't want narrative or an excerpt of the logs, I want the full logs

if you're not going to provide that, I can't help you

[tidal musk]

just strip the ip addresses with simple sed script

hiding plugins is also dumb because of security by obscurity

as if someone's really hunting your collection of premium plugins you paid 700 dollars in total

what's the issue then

are they going to get your plugins' source code by seeing their name?

no

that log file is completely useless

99% of it is btlp misconfiguration spam

and what should it even show?

[reef fulcrum]

Stop pinging me.

[tidal musk]

there's nothing useful

literally

whatever, good luck trying to figure out what's wrong with your setup

[reef fulcrum]

You're saying it's hanging at auth

and you have some weird ass plugin dealing with auth

replicate without that plugin 🤷‍♂️

[royal hawk]

It’s hanging pre-auth

[tidal musk]

[04:35:51] [cpvpBungeeAuth Pool Thread #11/INFO] [cpvpBungeeAuth]: Gracz HAMMERxPL dolaczyl do gry [PREMIUM]

hybrid mode login huh?

[royal hawk]

Remove that auth. plugin

And see if it still happens

[tidal musk]

if it doesn't, then culprit is clearly the plugin

rip

[royal hawk]

Then run a server instead of a proxy. See if there you’d still have connection issues

If yes then it’s your networking

If no then the natives on your system may be at fault

[reef fulcrum]

the client disconnected

[04:35:27] [Netty Worker IO Thread #5/INFO]: [/ip:22657|HAMMERxPL] -> UpstreamBridge has disconnected

UpstreamBridge refers to the clients connection, that was lost, so the other was lost, it getting stuck past initial handler, god knows, But, ServerConnector coming up means that it allowed the connection past the initialhandler and tried to connect to the actual server itself

if you wanted to debug that deeper than the logs, you'd need to grab out a sampler or potentially a debugger and see what's going on

[tidal musk]

have you ever heard of google?

look, if you don't put any effort into researching stuff yourself then this party ain't going to last

[reef fulcrum]

Well, debuggers imply having the ability to actually debug code, samplers, sample time, so if it's a logical error somewhere, you're screwed, if something is stalling, it will show up, visualvm/yourkit is better, but, if you gotta, spark

But, none of those are tools we have any inclination to help you with, especially debuggers

no

google

using a debugger is not a "here's a 3 step guide"

I'm not going to spend the next few hours teaching you how to use one

Your IDE literally has a method of attaching to the JVM to debug stuff

If you google, you'll find guides on how to do this with your IDE

[marble kelp]

you can still remote debug it, it's just a bit more annoying

doing it locally is usually best for testing

[reef fulcrum]

use an SSH tunnel

(you really don't want to expose debugging ports open to the world...)

no

[tidal musk]

Why did it suddenly starting printing many things

How do I turn Debug mode off

[proper prawn]

see lp config ig

or waterfall cfg
idk

[dull dock]

did you run /lp debug or something

[tidal musk]

Not really

Its bungee

lpb doesnt have debug mode

or at least doesnt have /lpb debug

[dull dock]

yes it does

[tidal musk]

Do you have any idea on how to turn off?

[dull dock]

might be called something else

idk, ask on discord.gg/luckperms

[proper prawn]

/lpb log?

[dull dock]

yeah, that possibly

[marble kelp]

the linux server itself? Oo

what do you mean by "lag"? network lag or actual process lag?

sounds like a network issue

unless htop/ps shows cpu usage spikes or processes that you have no idea about lol

first you need to figure out where the issue is. e.g. your server setup, your host network (your host should have a network usage map, maybe someone is ddosing them)

or maybe someone is attacking your server directly

the status page of your host should have some information about their network state (e.g. ovh's weathermap)

also you should have some monitoring programs installed which track ping times to external servers and general network usage etc.

munin, grafana

lots of different system/network monitoring programs available depending on what the goal is

maybe just keeping an eye on a simple console graph might do it

also do you get connection lag on your ssh session when this happens?

by looking at it

and coming to conclusions where the issue is. then when you know at which point the issue occurs then you will be able to look at what is causing it

[marble kelp]

generally speaking you wait until the issue occurs again and see if you can spot any difference in the data compared to when it doesn't occur and everything runs smoothely

also don't ping -.-

I'm not sure why you would need to disable the firewall for this? just put the webinterface behind a login or use a ssh tunnel to access the local resources of the server directly

you analyze the graphs and data it provides you

then you didn't set it up right, read their documentation and install instructions I guess

then I suggest fixing that

that sounds like you didn't setup your network server properly

and I never used grafana so all I can do is suggest looking at their docs and suggest that you think about how to properly integrate that with your setup

you are the sys-admin after all so you know it best

because it's a tool that can help you figure out certain issues

well that has nothing really to do with hosting a waterfall proxy so you are going to have to ask their support for that

(or ask in #general I guess, maybe someone who knows that tool is willing to help)

of course you can use any other network/system monitoring tool if you think you can use a different one better

(such tools is something that you really should've have had installed from the beginning. it's extremely important to have information if you are administrating servers/networks)

[mystic sky]

Has this ever happened to you?

[mystic sky]

I seemed to be a ddos using incorrect query requests, can be fixed with iptables

[mental charm]

Not that address, but I'm getting constantly pinged by

Is that normal?

[reef fulcrum]

it means something is pinging the server

[mental charm]

I'm aware 127.0.0.1 is the local address

[marble kelp]

Project Waterfall build #380: SUCCESS in 3 min 34 sec: https://papermc.io/ci/job/Waterfall/380/

[mental charm]

Would it be normal for the localhost to ping like that?

[reef fulcrum]

if you had something running on there pinging the server...

[mental charm]

It's just a CentOS 8 installation with AMP and 3 other Paper servers

I'm only asking because DiscordSRV logged someone leave and right after had the first join message right after the disconnecton and can't find anything from the Waterfall logs saying they connected, seen from EssentialsX is saying they have an IP of 0.0.0.0 some how

[unreal stag]

@mental charm Methinks you didn't secure your backend server

Please, read a tutorial on iptables.

[severe badger]

With that information, no
Use a profiler and find out what's doing stuff

[tidal musk]

hey, if the account migration to microsoft happens, is it still be possible to use bungeecord/waterfall? as i know, bungeecord needs cracked servers.. but will cracked still be possible? idk

[marble kelp]

yes

[strange brook]

[tidal musk]

okay.

[dull dock]

And bungeecord doesn't need cracked servers. You just set it up wrong if they are cracked

You turn the servers to offline mode, but you enable bungeecord mode on them and don't port forward their ports

[radiant falcon]

hopefully you all can help me. I have been working on a server, added it to the bungee (waterfall) network, changing the server.properties, bukkit and spigot files on this backend server, connected to the lobby and now cannot connect to this server but can connect to other servers on the bungee - I have obviously missed something simple. I get the error Kicked whilst connecting to server: Please join directly on the example.com Console on the new added server says disconnecting com.mojang.authlib.properties.Property@198...., legacy=false

[reef fulcrum]

You have a dumb plugin installed preventing you from joining

[radiant falcon]

Yes!! Ty I have just remembered what I did not change, thanks Cat you kicked my grey matter into gear - lol

[reef fulcrum]

I mean, that plugin is dumb anyways

Use bungeeguard if you really must use a plugin

[radiant falcon]

nope, I forgot to change the bungee ip lol

[reef fulcrum]

preventing based on hostname is easily bypassable

[bold parcel]

this is just a dumb question

but why differentiate travertine and waterfall?

does 1.7 support limit some other functionalities?

[reef fulcrum]

Provides a level of separation for the code as that patch is meh, makes updating easier

[bold parcel]

makes sense, thanks :p

[royal hawk]

meh is a nice way of putting it

I sometimes wonder how long you’re gonna keep it around

[bold parcel]

can't imagine it's much fun to maintain

https://howoldisminecraft1710.today/

[dire plank]

is there a plugin making this?

[slender terrace]

doesn't really look like it

[unreal stag]

disable the netty async dns resolver in waterfall.yml @dire plank

[cold token]

hey there

why do the servers behind the waterfall have to be in offline mode?

[marble kelp]

because the proxy does the authentication and forwards the info to the servers behind it

if it didn't then players couldn't connect to the servers as you can't intercept the auth process

(for good reasons lol)

[dull dock]

but if you set it up all correctly, it will behave just like an online mode server

[cold token]

yep

gotcha

question to you all geniuses

how do I make players reconnect to a fallback server if their original isnt on

[mild rover]

plugin

[lavish furnace]

Hey there !

I have a Waterfall with 150 players. My waterfall restart every nights automaticaly

How much ram do you recommend for 150 players please ? (running for 1.16.3 servers)

I only have Litebans on plugins.

[reef fulcrum]

512MB + 256mb per 100 players or something like that iirc

There is no real reason to restart a proxy, tbqh

[marble kelp]

I restart every night just to be sure that plugin updates make it in across the whole network every day and I don't have to bother with manual updates. helps if you only have one timezone to worry about xD

[bold parcel]

pheonix i sure hope you aren't auto updating

[orchid raven]

someone said to ask here so

how do i make it so theres more than one server players can join
so like
play.domain.com would be a hub with portals to all the servers
smp.domain.com would be the smp server direct join so they dont go through the hub
omnifactory.domain.com would be a direct join for a modded server

can i do that on one physical server(im using ubuntu 20.04)

[orchid raven]

im so lost idek how to begin setting up waterfall

[royal hawk]

@orchid raven read up on how forced hosts work on bungeecord. That’s 95% what you’re looking for

[delicate phoenix]

Is there a restart plugin for bungee 🤔

[round ocean]

Just ctrl + c. Bungee starts so fast no need for that.

[marble kelp]

@b​lu​el​y no, I update all my stuff manually in a central folder and sync it across the whole network depending on which server needs what plugin

[bold parcel]

smart pheonix, smart

i have yet to set up a system like that (i only did it for paper itself :p)

well, and all my private plugins

[marble kelp]

it's just one rsync command in the server startup script lol

rsync --existing --checksum --archive --copy-links -v /path/to/central/plugins/folder/*.jar plugins/

(and being rsync it obviously works via network too)

[bold parcel]

i take a bit of a different approach via my ci

i just wget from my ci whenever the docker container boots up

[orchid raven]

does waterfall/bungeecord actually run the servers or do i need a seperate terminal window?

and if i do how can i do that on ubuntu

[proper prawn]

waterfall is just a proxy

your servers need to run in a separate instance

[orchid raven]

alright

thats what i thoight

do you know how to do that on ubuntu?

[proper prawn]

screen

[royal hawk]

Oh please don’t

[proper prawn]

whats so bad about it?

[royal hawk]

Either use a container system or use services for servers. Screens are a bad way to hold a console session against a wall

[orchid raven]

i tried using docker but i couldnt figure out how to switch to a different container or just go back to the base os when i did something that didnt halt

well actually

i couldnt figure out how to do it even if it did halt

[royal hawk]

I can’t exactly recommend it but Pterodactyl is always an option

It’s a bit finicky

[orchid raven]

im gonna try to figure out how to use docker

thanks

[lavish furnace]

zzzCat, actually i have 4go of ram on my proxy, so its too much ?

[marble kelp]

F​iv​eP​B: well screen has been working fine for decades so ¯_(ツ)_/¯

runs

[royal hawk]

I swear phoenix some day

[upbeat wave]

i just setup a proxy, and i'm pretty sure i did it correctly - but is there anyway to test the security?

[bold swan]

Try joining one of the backend servers directly rather than through the proxy

[spring marlin]

Hi

Hello, does paper have support for servers with mods?

[marble kelp]

no

[spring marlin]

I say, I correct myself, waterfall

Does Waterfall have support for servers with mods?

bot :,v

[cold token]

why do the waterfall max player counts not save??

i try and set it in the configuration and it just overwrites back to 1

[bold swan]

I don’t remember exactly which but there’s two options - one that sets the actual player limit and one that sets the visual player limit. Are you setting both or just the real limit?

https://www.spigotmc.org/wiki/bungeecord-configuration-guide/

That guide explains it

[royal hawk]

@spring marlin yes. You can use 1.8-1.12.2 servers running forge and spongeforge with Waterfall
You just need to set up spongeforge on those servers in bungeecord mode and have Waterfall configured for information forwarding and forge support accordingly.

Gotchas: Some mods break comparability or conflict with Proxies or spongeforge- If you encounter that we likely can’t help you.
Secondly; it’s impossible to use forge 1.13 and newer with any kind of proxy for technical reasons.

Fabric servers and mods tho are fully supported in even the latest versions

[tidal musk]

I am getting a big attack. This may be caused by what. In this way, more than 200 articles per second are coming.

[reef fulcrum]

Well, yea, you're being sent bad packets

Configure your firewall to limit the connection rate, see the pins for an example of that with iptables

[upbeat wave]

F​iv​eP​B: well screen has been working fine for decades so ¯_(ツ)_/¯
wait is screens bad ?

[mint terrace]

Depending on how complex you want to get, you can also filter packets by byte count

I would love to get the log of that attack btw

[worn raft]

Completely new to waterfall and bungeecord in general. Tried linking a few servers together which include a lobby, a survival server and a FML server.

Ran /server survival but got this:

Survival - 1.16.3
Lobby - 1.12.2
Waterfall - 1.12

Every instance, except survival, is running ViaVersion

[marble kelp]

update waterfall if you want 1.16 support

[worn raft]

Will that work with my 1.12.2 lobby and 1.12.2 forge server ?

[marble kelp]

and remove viaversion from the proxy if you already have it on the other servers

[worn raft]

oh, okay

[marble kelp]

the proxy supports 1.8-latest

[worn raft]

Lemme try that. Thanks

[supple fulcrum]

Hi everyone, I am on the latest waterfall and I have a bug. My players seem to rubberband and get stuck on some servers. I have no clue what is happening.

It stops when I turn forced host to false

But I really want them to connect to the lobby server first

https://www.youtube.com/watch?v=ulFGzS2VmiI
this is what is looks like but this isn't a video from our server

I do have to add that our instances behind waterfall are all the latest version of Magma 1.12

[reef fulcrum]

forced hosts does not change anything with how the connections work, etc, etc

Some people for some reason have issues with bungee in general where it causes some issues with their network performance, we have no idea how/why, nor do we have the means to debug it

[supple fulcrum]

https://github.com/SpigotMC/BungeeCord/issues/742
this seems to be relevant

[reef fulcrum]

players freeze

that implies a total freeze, nothing to do with that?

[supple fulcrum]

well that video I send comes from that github bug thread

the title is just wrong

they claim to have fixed it in commit 230cca0
but I can only imagine that the mentioned commit is already in waterfall as this is an issue from 2013

[reef fulcrum]

I mean, if you wanna test if that's an issue again or not, in waterfall.yml, set the option to disable metadata rewriting

[supple fulcrum]

I'll try that

We are using modded so that might very well be the case.

[atomic star]

Hi i would like to ask if i can use waterwall to make one main paper server and then an 1.16.3 paper server and an 1.16.3 forge server?

[marble kelp]

you can try but you most likely will run into issues with forge

[atomic star]

what could this issues be?

[marble kelp]

mods not properly handing a switch from a non-forge to a forge server with the mods

ideally you want forge clients to connect to the forge server when joining instead of going through a lobby but it kinda depends on what mods you use

[atomic star]

and is there an tutorial how to set up an waterfall server?

[reef fulcrum]

use the bungeecord install guide, but, really, it's literally just throwing up a bunch of servers and configuring the proxy to see them, and securing your backends

[atomic star]

ok thanks for your help

[royal hawk]

@atomic star should be worth mentioning that no proxy supports forge 1.13 and newer. The paper server will work, the 1.16.3 forge server not.

[atomic star]

would that mean that an forge 1.12.2 server should work?

[reef fulcrum]

outside of mod compat, yes

[sharp maple]

guys bungeecord or waterfall?

[reef fulcrum]

I mean, you're asking in waterfall, we're ofc going to say waterfall

[still citrus]

the real answer is velocity

[reef fulcrum]

busted OS?

It's blowing up reading the mac address of the system

[echo path]

Can I fix this somehow? oO

[reef fulcrum]

2 second google suggests trying to disable ipv6 support, it's a bug in log4j, been meaning to see if we can update that without breaking 200 plugins

[green palm]

Updating log4j2 to a compatible major release won't break any plugins correctly using it

[half kiln]

I am trying to setup waterfall for my network on vps

but everytime I am trying to join it I have message If u wish to use ip forwarding enable it in config

but it's enabled

[reef fulcrum]

you need to join the proxy, not the individual backend servers

[half kiln]

what's the adress of proxy then ?

[reef fulcrum]

It's your proxy

The proxy listens on whatever address you set in the listener section in the config

[half kiln]

this ? host: 0.0.0.0:25560

[reef fulcrum]

Yes

So, your using port 25560 on whatever IP address your server is

[half kiln]

Do I need to change the 0.0.0.0 to my server ip ?

in config

or it's fine

[marble kelp]

it is most likely fine

[half kiln]

and just try to join my server using serverip:25560

[marble kelp]

your error indicates that you can join the proxy without issues

wait no

sorry, misread the error

yes, you need to join via port 25560 or change the port so that it runs on the default one and make your paper server run on localhost

[half kiln]

when I am using raw server ip my server appear on serverlist

but when I try to add this port just nothing happens

just like it was offline

mb

it's probably cause version of my hub is 1.8

and I am trying to join on 1.16

[marble kelp]

that should lead to the server kicking you because your version doesn't match

[half kiln]

I will try to install via version anyway maybe

[marble kelp]

would be better to use latest paper tbh

[half kiln]

can I somehow change the host so the ip which player will use to connect to server won't include port ?

so they can use raw domain name ?

[marble kelp]

yes, set the port to the default minecraft one (25565)

[half kiln]

oh thanks

[17:29:57 WARN]: Could not bind to host /0.0.0.0:25565
io.netty.channel.unix.Errors$NativeIoException: bind(..) failed: Address already in use

hmmm

[marble kelp]

well you need to make sure nothing else is running on that port

[worn thunder]

Probably already in use by one of your servers

[half kiln]

yes I must check that

[marble kelp]

if you have a different server running on the same machine then you need to change the address/port to something else

[half kiln]

nah the port for my hub is server-port=25561

so idk what's causing it

[proper prawn]

considering you are using a proxy, you probably have more servers than your hub server

[half kiln]

3 of them but I was running only hub and proxy this time

oh shit

I am stupid

I left old instance running

okay now it's working

and throwing outdated client

Can I install viaversion on bungee, or is there a way to enable multiversion joining ?

[reef fulcrum]

recommended to install it on the servers

[half kiln]

yes I installed it

but probably bungee itself refuses to let me join

[reef fulcrum]

the proxy supports 1.8-1.16.3

[delicate phoenix]

Hello! Is there a plugin to check if the proxy is spamming errors, and if it does run the command end?

I'm trying to make a way, that if someone sends garbadge to my tavertine proxy, and it starts spamming trash, restart it.

[spring marlin]

w

@spring marlin yes. You can use 1.8-1.12.2 servers running forge and spongeforge with Waterfall
You just need to set up spongeforge on those servers in bungeecord mode and have Waterfall configured for information forwarding and forge support accordingly.

Gotchas: Some mods break comparability or conflict with Proxies or spongeforge- If you encounter that we likely can’t help you.
Secondly; it’s impossible to use forge 1.13 and newer with any kind of proxy for technical reasons.

Fabric servers and mods tho are fully supported in even the latest versions

how much ram should I allocate for a waterfall server with 200 players?

512MB to 1GB

@reef fulcrum 3 days ago you helped me with disabling metadata rewriting. This seems to have fixed all our major rubberbanding, shaking screen and getting stuck bugs without it breaking any of our plugins or mods. Thanks a ton!!!

[tidal musk]

epic

[green palm]

So apparently this QuietCord builds against bungeecord 1.8-SNAPSHOT ... nice

[marble kelp]

why would you even use that plugin?

[green palm]

No idea, I'm just generally curious

[marble kelp]

(because Waterfall has an option to disable these messages iirc)

[tall crest]

Hey, we're having issues with chatting & commands through bungeecord. This issue is somehow caused by a specific server when I add it to the network though it effects the entire network. The issue that is caused is when players execute commands or chat that will get canceled out, no commands will work even in console and the only limited commands that end up working are bungee ones. There is no error message given in the console or to the players, it just simply doesn't do anything. This is only when I add my Towny server, though when I added it, then removed it. It still effected the entire network after I removed the Towny server. I have tried getting support elsewhere though haven't had much luck in fixing this. I've already tried resetting the config.yml though that didn't have much of an effect. Below is my plugin list for all my servers.

In my bungee I currently only have Luckperms bungee.

I am using Avalanche (fork of waterfall) for my proxy server though I thought I'd ask here to see if I could maybe get some help.

[worn thunder]

You have so many plugins, it could be anything.
If the server is currently not connected to the network, why not remove plugins until it works?

[lavish furnace]

Hello there :)
I would like to know if you think it's normal the byte[] value is so high?
https://spark.lucko.me/#d9si9fuK1c
I only have 80 players connected on my waterfall and it has been online for only 2 hours
With 4gb of ram allocated (i have between 100-150 players online), I have an OUT OF MEMORY after about 17h of uptime.

Im using recommended flags

Could it come from this setting ? remote_ping_cache: -1

[reef fulcrum]

take a heap dump, there is a JVM flag to produce one on an OOM

make sure that you're running the proxy on linux too

[royal hawk]

@lavish furnace are you running the plugin TAB by any chance?

[unreal stag]

SkinsRestorer

[lavish furnace]

Absolutly not

Oh that skinrestorer ? Omg ...

[tender axle]

Does Waterfall support connecting to a Fabric server?

[marble kelp]

if its running in offline mode, sure

fabric is just a modded vanilla server, you might want to installa mod to forward ips/uuids though

e.g. https://www.curseforge.com/minecraft/mc-mods/fabricproxy

[wild geyser]

How do you guys update plugins across multiple gameservers on a waterfall network? I currently have 2 and find it a pain in the ass to update 30 plugins on each server. In the close future we might have 3-4.

[severe badger]

If you check plugin updates regularly and perform those, you don't need to update 30 at once

[grim umbra]

How can I disable this:

please ping

[severe badger]

Is that part of /send

[grim umbra]

How do I use /send?

woah

[severe badger]

/send will reveal the context

[grim umbra]

I'm talking about how to remove the message

looks like its part of a plugin

i think

bc other servers dont have it

I have 80 plugins ;-;

[severe badger]

80 bungee plugins?

[grim umbra]

no

[cerulean temple]

yoyo

my server keeps telling me Unable to authenticate - no data was forwarded by the proxy.

even tho im joining thru proxy

[reef fulcrum]

Sounds like you enabled velocity mode or something

[green palm]

well, velocity is the right choice anyway

[cerulean temple]

huh

im using a thing

called tcp shield

if thats helpful

[green palm]

you probably want to ask their support, as I remember the tcp shield plugin needs to access some proxy internals to rewrite information

[reef fulcrum]

best guess is that you installed that thing wrong or you set something wrong up 🤷‍♂️

[cerulean temple]

well

im bad at dns records

ngl

[reef fulcrum]

Assuming that you didn't set the velocity setting

[cerulean temple]

assuming i did this wrong

?

[reef fulcrum]

You'd need to contact them for support

[cerulean temple]

alright

[woeful bronze]

hi, ive been thinking about hosting a minecraft server with mods for my friends, unfortunately my friends don't have premium and i want this sever to have register/login plugin. i know that mods and plugins dont play well together but do you know any fork with support of mods and plugins for version 1.8+?

does waterflall support plugins also?

or any other alternative for verification of offline mode without plugins?

[delicate phoenix]

Waterfall is a proxy, witch balances and manages your players in your network between multiple servers. You can install plugins on it, and also use it in offline mode.

It's a fork of bungeecord.

[woeful bronze]

ok

i am new in hosting community and dont know java well

[delicate phoenix]

To run a server you need a server jar, witch is for as axample paper, with offers a really good optimisation, and supports plugins, but not mods.

[woeful bronze]

i am using it right now but im thinking about modded server and im thinking about fork of paper creator because paper works the best

[proper prawn]

you cant shove mods and plugins in 1 piece

that's just asking for problems

[woeful bronze]

i know

but i need to have some sort of verification for offline mode server

[proper prawn]

dont run an offline-mode server?

[woeful bronze]

my friends dont have premium

i should force them to buy mc

[severe badger]

Plugins exist that can do that, but be aware, offline mode is not very much supported in here

For obvious reasons

[delicate phoenix]

Try authmereloaded, and authmebungee for bungee

[proper prawn]

i should force them to buy mc
then do it!

[woeful bronze]

ok thanks for help

[tidal musk]

Are items lost after changing the nickname on online mode?

[proper prawn]

on online-mode - no

the uuid is the same

[tidal musk]

but if I have Premium login on online mode false

[proper prawn]

wdym "premium login"

[tidal musk]

Plugin which ables to login without password

[marble kelp]

you want online-mode true, not false

if it's false then all players are in offline mode and changing the name will change the uuid and therefore player data

[proper prawn]

unless that plugin manipulates uuids, the items will be lost because the uuid has been changed

[tidal musk]

ok

thx

[candid moat]

Hey - I've used paper before and it ran so much better than other server types. My understanding is that waterfall might be able to provide the same thing but with forge? I'm just looking to avoid problems like I did with Paper but I'm working with mods now

[still citrus]

waterfall is the same thing, but not for forge

it's a replacement for bungee

it is a proxy that allows you to connect multiple servers together to form a network

it doesn't run minecraft, it just shuffles players around the actual backend servers

[candid moat]

Oh gotcha

I misunderstood. I'm looking for something that can run with mods - I read paper isn't compatible?

[still citrus]

there are some kinda fringe projects out there that try to mash the 2 together

with varying levels of success

[proper prawn]

But all of them break everything

[candid moat]

Paper runs wonderfully for my 1.16.3 vanilla server. I'm just looking for something that will be stable for mods as I've had issues before and figured it was worth asking in here as paper was great for me

[still citrus]

well, paper implements the Bukkit API, which is for plugins, not mods

running mods requires completely different server internals

[reef fulcrum]

Paper runs plugins, not mods, if you want mods, you want fabric or forge, but, paper + forge does exist but we refuse to even deal with it, and the community which pushes it generally refuses to support it to because of how janky it is

[proper prawn]

Forge 1.13+ does not work on proxies afaik

Fabric works fine however

[candid moat]

For sure. I was gunning for something that could do plugins as well which is why I was looking here specifically. Fabric rings a bell though, thank you

[lusty oasis]

Hey! I have a question. Let's say I am supporting 1.16.3. If 1.16.4 releases, how can I update to 1.16.4 without restarting, and like fast?

I guess its impossible

[reef fulcrum]

You can't

[lusty oasis]

Also, is there a dev build server for waterfal? So I can update like faster?

the jenkins one

[reef fulcrum]

all builds are "dev" builds

[lusty oasis]

On papermc.io?

[upbeat wave]

Does viaversion go on backend servers or the bungee itself?

[lusty oasis]

or this or this, i'd recommend all backends

[bold parcel]

@proper prawn forge 1.13+ works on velocity afaik

[reef fulcrum]

it doesn't, afaik

Idk why but I thought you said about fabric...

Basically, forge requires that you hand-shake with it when you login, you can't re-do the handshake post join, given that the client isn't in phase for that

[bold parcel]

oh

yeah

it doesn't support forge >1.12

my bad

[reef fulcrum]

Bungee basically relies on just reforwarding that info, technically, we could try the same approach, but, that creates the same issues as we have now, and added more complications on it last I recall

[bold parcel]

i was thinking about the other velocity 1.13 stuff

[tidal musk]

Hello! Is there any way of fixing the “Error occurred while contacting login servers, are they down?” Message? It’s annoying and I have to retry connecting to my server like 20 times before it lets me in. Any help is much appreciated!

[proper prawn]

there was an error contacting login servers

that probably means the login servers are down or the server has no internet access

[tidal musk]

What can I do to fix that

[proper prawn]

if the login servers are down, all you can do is wait

if the server has no internet access, you need to make it so it has internet access

[tidal musk]

It’s been persisting for the last few days tho

It has internet

Nevermind, I found a solution. Thanks for the help tho

[royal hawk]

forge 1.13+ is in dev for velocity by me

when I finish that ill PR a patch for it to Waterfall at a later date

[tulip quarry]

Anyone know if waterfall is compatible if FML2 protocol?

[tidal musk]

what's FML2 protocol?

[tulip quarry]

@tidal musk is the new FML protocol for Forge 1.16.3

[tidal musk]

anything past forge 1.12+ is not supported

[tulip quarry]

can be supported?

@tidal musk

[tidal musk]

idk

[tulip quarry]

anyone of the devs, know if it will do it?

[marble kelp]

if someone of the people using forge PRs it, sure

[tulip quarry]

I use it xD

[tough marsh]

Hi! Can help me anyone? How can i set default server in waterfall. When you enter the server teleports to it

[proper prawn]

i believe the first server in the priority list is the default one

you'll have to enable force_default_server if you want everyone to get warped to there

[tough marsh]

i believe the first server in the priority list is the default one
@proper prawn No :(((

you'll have to enable force_default_server if you want everyone to get warped to there
I have this for true

[marble kelp]

literally what was already said

[royal hawk]

Didn’t read for the reason that this person is on the bdc spam list

[marble kelp]

what does that even mean? lol

i assume bdc = betterdiscord

i dont even know how i assumed that

[marble kelp]

https://www.bdc.ca/en/articles-tools/marketing-sales-export/marketing/anti-spam-legislation-what-you-need-to-do-now

[reef fulcrum]

I was speaking to some people a while back, and, would server switching be viable with it? as thats' what the issue was last I recall was that some stuff was moved over into the login protocol phase, meaning that we can't really re-handshake with the client

[royal hawk]

@reef fulcrum about the technicalities; yes you’re correct, newer forge uses login plugin messages that can’t be resent after the client switches into play phase

So my approach here:

• The forge client and the proxy get an additional response type for server list ping, that will indicate that the target server is a proxy
• The forge client and server will get an additional plugin message to establish that the client is connected to a proxy
• This enables a client reset-to-ready plugin channel which will also be used after to re-negotiate the forge protocol using the proxy as normal forge client

[reef fulcrum]

So, you mean, you need a mod on the client to work? or?
