[tidal musk]

yes

if you don't firewall backend servers

or use other measures to protect them

also reeeeeee i'm absolutely lost

i'm at area where i get constant ~15k rx packet flow

and then suddenly it drops down to 0

[reef fulcrum]

Waterfall itself isn't the issue, it's exposing your backend servers to the world without any form of security that does it, e.g. firewall, bungeeguard; If you setup and protect your stuff properly, you'll literally have 0 issues with that

[tidal musk]

Hello, how secure is an IPIP tunnel? If I hide my server behind it (DDoS protection) it can be good? (Nobody knows the IP that I want to secure.)
Other question: What kind of tunnel Waterfall/BungeeCord uses?

huh

waterfall/bungee is just a proxy

[reef fulcrum]

Bungee doesn't use a tunn... ^

[tidal musk]

Okay. Do you know anything about the IPIP tunnel? It can works well?

[reef fulcrum]

Never used an ipip tunnel

[marble kelp]

just use haproxy xD

[reef fulcrum]

haproxy doesn't work without proper support for it

[marble kelp]

(or follow any of the guides on ipip tunnels I guess)

[tidal musk]

IPIP tunnel or move the waterfall server to a ddos protected server?

[marble kelp]

do you really need some special support if you only want tp proxy to a single server?

[reef fulcrum]

Why are you looking to tunnel in the first place?

[marble kelp]

he said ddos protection before ;)

[tidal musk]

Yes, I would like to ddos protect my dedicated server.

[reef fulcrum]

See, my general suggestion is to just run a few bungee instances on VPSes on ovh or something

[tidal musk]

Okay.

[marble kelp]

that gets unwieldy quickly though e.g. if you want to use LuckPerms with the same database on bungee and server. having a vps contact the database on another server might add some unwanted latency

[reef fulcrum]

that, and probably something like egg82s anti vpn plugin from spigots site as it has a few good blacklists, not perfect but no blacklist is

The issue is is that it depends on the level of the attack

[marble kelp]

yeah, a DDOS protected host wont protect you against a couple hundred bots joining xD

[reef fulcrum]

If you're tryna mitigate packet flooding, having extra instances around can help people stay connected, but a tunnel would work as well; in the case of people just opening a few dozen connections, having something that can handle that spread out is pretty important as standard ddos protection ain't going to do much about that

[tulip fossil]

Can you run several Bungee instances that connect to the same backend server?

[marble kelp]

yes

[tulip fossil]

And is there some sort of round-robin mechanism so that you have single entry point for players? Sorry, I'm just starting to dabble in the Bungee stuff

[reef fulcrum]

you'd do that with your DNS generally

[tulip fossil]

I see

[marble kelp]

or haproxy I guess

[reef fulcrum]

just have a few A records pointing to different IPs and it should round robin them

[marble kelp]

(if you want a physical single entry point that is)

[reef fulcrum]

the idea is to avoid a single weak link

[tulip fossil]

yeah, DNS makes sense

[marble kelp]

the internet is packed with weak links my friend

dns round robin is okay; but doesn't work perfectly all the time

[austere solstice]

how to autocomplete names in a new command like in /send name server..... tried some things but nothing worked

[heady sedge]

Is there any way to send players to my second server under priorities when the first server is full?

[outer pawn]

Where do I put my config so you could help me with this error

[reef fulcrum]

pastebin or something akin to that

[outer pawn]

https://pastebin.com/EKhX2g8D < Config
Plugins:
Network Manager

• Rest API
• Discord Bot
  Luck Perms

[reef fulcrum]

The fact that you have a plugin called network manager is pretty...

Basically, the only way you'll see that error message is if there is no server marked for a person to connect to

your config itself is fine, but some plugin is prooobably breaking that

[outer pawn]

I did use the Server Manager for it but it never acted up on bungee like it is now 🤔

[teal robin]

I've created a fork of a scoreboard called Quickboard and updated it to support 1.14. I'm trying to figure out why one user is having an issue with some text not appearing in a board.
Their server is using Waterfall and they only use the plugin on their hub (1.14 paper) . Does something need to be changed in the waterfall config?
So far they've tried disable_entity_metadata_rewrite set to false and true, but there's no difference.

[marble kelp]

@w​oo​ly​_r​ab​bi​t some more details would probably help. like "what text" to begin with

[frail brook]

Any way to prevent waterfall from accepting pings from old versions?

https://i.imgur.com/WGEI2nJ.png

I'd prefer the red cross saying "1.14.4" instead of the ping

[marble kelp]

iirc. there is a config option but I don't think that actually influences the ping display, just what the version says when pinged

there should be some simple plugins around to restrict the ping version though

[frail brook]

I guess I can use ProxyPingEvent

[reef fulcrum]

ping passthrough would forward the ping to the original server

Only other option would be to DIY' with a plugin or something

[frail brook]

ping_passthrough works well, but requires force_default_server

so, plugin it is

[frail brook]

No plugins/update folder on waterfall?

[reef fulcrum]

nope

[teal robin]

@acoustic adder part of the lines of text displayed in the scoreboard, the first couple of words appear on each line. Some of the lines contain placeholders and we’ve confirmed already that papi can parse them

[reef fulcrum]

You're not hitting some text limit are you?

Waterfall itself shouldn;t really be doing anything there

[mint pewter]

Hi, I'm working on a project to split up a MC world over multiple MC instances ( see https://www.youtube.com/watch?v=0fzjOwTmFH8 ). So far I've modified Paper & Waterfall a bit to coordinate moving players from instance to instance.

[mint pewter]

I would liky to make the transition between two servers seamless

as in, no loading screen, and ideally, since the chunks were already loaded on the client, no chunk reloading.

Does anyone have ideas on whether it's possible, and if so, how?

[reef fulcrum]

There have been servers that have done it

It does require a lot of consideration about how you handle border chunks as a whole

[mint pewter]

yes, I am aware

[reef fulcrum]

seemless teleportation would basically be stripping out the dimension change

[mint pewter]

I see

Anything you could point me to that explains this transition ?

(I've been browsing the protocol specs, and I've been experimenting, but not much progress as of yet)

What I have succeeded in doing is the following: https://www.youtube.com/watch?v=UC9dTWnxd4s

(DiscordBot) MIMC proof of concept no loading screen - length 41s - 1 like, 0 dislikes (100.0%) - 18 views - nckk mc on 2019.08.04

[mint pewter]

By sending playerlocation packet right after reconnecting, it silences the loading terrain screen

However this depends on your PC's speed also. Slower PCs apparently still see loading screens.

@reef fulcrum Could this be it: https://wiki.vg/Protocol#Respawn ?

[reef fulcrum]

The idea is that you try to hide the fact that a dimension/server change even occured

[mint pewter]

yeah exactly

the client has already loaded the chunks

all the entities and everything are there

Just before migrating the player to the new node, we save the state of those region files, and set them to read-only

then we reconnect the player to the new node, which in turn needs to load all the chunks the player is in

but we don't want it to communicate all that back

it's obsolete

from the player's perspective, at least...

[teal robin]

It might be a text limit. It’s just basic stuff. Nick: %luckperms_prefix%
I’ll double check it on just paper. He can always try a scroller/changeable text element, if it’s a character limit issue

He has some color codes in there too, and I believe those are counted towards the limit?

[mint pewter]

@reef fulcrum I have a trace of the packets the server sends the player: https://pastebin.com/aqZNztTb
Are the packets that make the client "dimension change" in there?

[reef fulcrum]

The server doesn't send it

Bungee fakes a dimension change

[mint pewter]

ah, so it's not actually the server sending these packets

gotcha

Could you point me to the part of the code where bungee does this?

[reef fulcrum]

ServerConnector iirc

[mint pewter]

Super, thanks a bunch!

[mint pewter]

@reef fulcrum Thanks again! The result: https://www.youtube.com/watch?v=kZ3adP3zdDE

[placid vigil]

anybody know how to get a global tablist for waterfall or bungeecord

[tidal musk]

😮 @mint pewter that's really cool

[left ruin]

@placid vigil plugin BungeeTabListPlus 😉

[full cypress]

@mint pewter Nice work on that transition. We were actually going to use something similar with that with the new skybounds rewrite to break the world into subservers to help with lag. but instead of depending on the region files to be the same, we were going to make island locations be on a global system that loads into world via mysql instead of region files.

[mint pewter]

@full cypress I think we're actually doing something similar to what you're describing. We call them partitions, and they are also dynamic, based on player location

The test I set up here, was only to demonstrate the concept

But we don't actually have fixed regions

We partition up the world into islands of players, if you will, where we try to eliminate contention on shared data (RegionFiles) by merging partitions whenever they come into a set distance from eachother (currently 2x region file size = 1024blocks)

@full cypress http://mc.pupu.be/ <- This javascript simulator demonstrates the concept as an animation

click around the map to add players

Nearby players get clumped into a partition (island)

All of this is coordinated by BungeeCord

[full cypress]

I wanted to do partitions, but then everyone fought me and said they didn't want a set number of servers. They wanted a "Spin them up as demand requires it" which is why we have to use global positioning instead of saying "x region of islands is on x server"

[high mason]

@mint pewter so it creates new server instances per partition? and how do you handle inventories syncing per server instance then?

[mint pewter]

it's partitions per server instance, not the other way around

when migrating users from server to server, we just use the vanilla synching mechanism

saving region files and playerdata

and loading them up again on the new server

[high mason]

ah alright

[mint pewter]

The point is, no two servers run the same chunks at the same time

[high mason]

right

[mint pewter]

(same RegionFile at the same time actually)

[high mason]

Sounds really cool. Good luck with it! 😄

Trying to setup something similar'ish but I just store each world on a seperate server instance with the same plugins and will sync inventories with redis

[placid vigil]

Thank you @left ruin

Works great <3

[high mason]

btw @mint pewter What is this for? some server you're working on? or just for fun?

[mint pewter]

See /dm

[feral crow]

Is there plugin, that allow me to connect to online mode server via Waterfall/Bungee?

(I need it for only testing, proxy is on my localhost)

I'm getting now server is online mode message

[reef fulcrum]

No, not with how bungee/mojang auth works

[feral crow]

:/

[eternal pond]

whats recommended view distance is survival server with 30 players

[austere solstice]

how can i just allow 1.14.4 versions via waterfall?

it shows 1-8 - 1.14

[pure wind]

@eternal pond depends on the machine

You should be fine with 5

[reef fulcrum]

enable ping_passthrough is the easiest way to get it to use the correct versions

That does force it to ping the backend server, however

[austere solstice]

mhm..

i add all my server via my plugin

so i can dynamic start my servers

is there a way to set the version via my plugin too?

[reef fulcrum]

Does the ping event let you set the protocol version?

"Yes"

Or, not...

[frail brook]

https://github.com/hiddenite/force-ping-version/blob/master/src/main/java/eu/hiddenite/ForcePingVersionPlugin.java

here's how I do it

version:
  name: "1.14.4"
  protocol: 498

with this configuration

[high mason]

ayy, figured something out, made a command to switch server that waits till it's done sending before sending the player to the server,
ex /server ServerB

and I get this on serverB

05.08 20:56:12 [Server] INFO UUID of player Soap_Turtle is 2c40859f-ea80-49be-a165-b0309646da42

(Added current time to the message to check how long time till it was sent)

new Thread(() -> {
            try (Jedis jedis = pool.getResource()) {
                jedis.publish(ITEM_SYNC_CHANNEL, player.getUniqueId() + "###save###" + System.currentTimeMillis());
            }
            ByteArrayOutputStream b = new ByteArrayOutputStream();
            DataOutputStream out = new DataOutputStream(b);
            try {
                out.writeUTF("Connect");
                out.writeUTF(args[0].toLowerCase());
            } catch (IOException ioe) {
                ioe.printStackTrace();
            }
            player.sendPluginMessage(this, "BungeeCord", b.toByteArray());
        }).start();

Not sure if that's the proper way to make a thread though :/

"Got a save request in 3ms" it's fast now

[reef fulcrum]

as I said, use a thread pool

creating threads its slow and wasteful

[dusk cradle]

Alright so I have a question about waterfall. I know it's meant to be more community based than bungee but howso. What patches have been implemented by the community.

I currently use bungee and I'm thinking about switching

I did a bit of googling but nothing really specified how it was improved besides handling more players and general performance

[reef fulcrum]

more community based is that other than my lack of time to go crazy with testing things over the past little while, we are more open to contributions from the community than upstream, e.g. the patch to disable entity metadata rewriting was based upon efforts from others and prior research, offers much better forge compatability and can cut out a fair amount of needless work for the proxy; Others are general improvements, cleaning up areas of code

[austere solstice]

Thanks :)

[olive robin]

does waterfall offer performance enhances like paper?

[cedar quiver]

I see this fairly often in my Waterfall log, what does it mean? https://i.imgur.com/odVOS2e.png

[reef fulcrum]

it means that something on your server is likely mangling packets

[olive robin]

I'm making a hub for my servers. Is 512mb enough for a hub?

My VPS is 10gb but I think ~512mb is enough?

[reef fulcrum]

Depends, really

[olive robin]

All I'm going to have is the portals to the other worlds.first time doing waterfall so a noob, will learn

[cedar quiver]

Electroniccat, would it be something on the waterfall or on the paper server they connect to?

[reef fulcrum]

more than likely on the server itself

[cedar quiver]

Any tips on how to find out what's causing it?

[reef fulcrum]

beyond "start pulling plugins", not really

[cedar quiver]

Oh well, thanks!

[olive robin]

is there a faq I can read on waterfall. Is waterfall a plugin or is it like spigot? Totally lost

[reef fulcrum]

It's a proxy server

[olive robin]

So I would still use spigot?

[reef fulcrum]

You would still need real mc servers, yes

[olive robin]

Ah I think I got it.

Thanks

[high mason]

anyone know of a good queue system? don't want everyone to join back after restart at the same time and kill the server 😛

[olive robin]

https://www.spigotmc.org/resources/queuesystem-1-14-support.44013/

[high mason]

Thanks 😃

[olive robin]

pretty easy google

'queue system spigot'

haha

[cedar quiver]

What do I change if my player count is only pinging lobby and not doing global player count?
Edit: Resolved via ping-passthrough

[high mason]

last time I did it, the one I found didn't work, thanks for googling for me 😛

[jade kindle]

what is waterfall? i just saw this channel

[tidal musk]

a fork of bungee

[olive robin]

Could not connect to default or fallback server, please try again later: io.netty.channel.AbstractChannel$AnnotatedConnectException

most of installed wrong

[night skiff]

Hi ! i don't know why but no one can't see other players :/
I have a hub server (vanilla on craftbukkit) and a direwolf server, both are in 1.12.2

[reef fulcrum]

100% depends on your mods and stuff

[night skiff]

before that's worked but we got kicked i don't really know why and in the logs that were write to i need to see the disable_entity_metadata_rewrite line and i set it to true and now we don't got any kick but now we don't see anyone :/

and the for the hub too ?

(sorry for my english :3)

[hard trench]

what happened here https://pastebin.com/fYHNzqf2

everyone got kicked off and the server was stuck at pinging

[reef fulcrum]

network went rip apparently

[hard trench]

this has happened multiple times

.-.

well good thing im switching hosts

but thats just bad

Heres the log, maybe theres some issue that causes it?

[twin sky]

do the servers have to be in offline mode to connect to waterfall?

[tidal musk]

servers hace to be in offline mode indeed

[twin sky]

okie thanks

just making sure

[tidal musk]

do not forget to firewall your servers and/or using BungeeGuard

[twin sky]

ok thanks

[cyan dove]

i'm running waterfall & paper for my smp server but everytime i login it takes a few seconds before my items appear in my inventory

also it lags a lot when i tp to a player, it sinks me into the ground for a good 3 whole seconds before my character's position resets

[tidal musk]

smells like poor connection to me

[cyan dove]

im getting 10ms

the server is hosted on my other laptop and the proxy is on my vps that i get a really fast connection to

[ivory basalt]

I asked in general and realized I should ask in here...
How to get waterfall to listen to connections on ipv6?

[reef fulcrum]

shooould just be able to slap a v6 address in a listener

[ivory basalt]

ab:32:032::1:25564 ?

because bungeecord, don't like that. And I tried a few toher things. So, if WF can deal with it, I'll swap to it.

[ivory basalt]

yeah, bungeecord freaked out

especially didn't like the brackets

[strange brook]

unabbreviated?

[ivory basalt]

didn't try that :S

longform though is meh lol

[strange brook]

(that looks ambiguous, shouldn't there be 8 groups?)

[ivory basalt]

that was an example :P

[strange brook]

like 25564 is too big to be a group

so that could error

idk

[ivory basalt]

but any neighboring groups of 0000 can be represented with ::

[strange brook]

isn't it only once tho?

like you can't have multiple :: either

[ivory basalt]

I'm fairly certain, sayd if your address is
2600:0000:0000:1111:0000:0000:0000:0001
it can be represented as
2600::1111::1

But I may be mistaken on that.
I do know, however that the spec says:
2600:0:0:1111::1 is valid for the example above in this msg.

[reef fulcrum]

How does it blow up?

[ivory basalt]

but since the first 4 segments will never be 0 in any address anyone would have access to, it's moot

Uhm.

Let me start a second copy so my players aren't affected

[strange brook]

2600::1111::1 is not valid

2600:0:0:1111::1 is

[ivory basalt]

OK, wasn't certain about the top, but it's moot for my case.

expected <block end>, but found '<scalar>'
 in 'reader', line 21, column 38:
     ... t: [2607:f1c0:801:1f00::52:9cf4]:25564

[reef fulcrum]

shove it in a set of ";s

[strange brook]

this is why you just post errors

[ivory basalt]

"2607:f1c0:801:1f00::52:9cf4":25564

[strange brook]

instead of asking backwards questions like "is ipv6 supported"

no

"[addr]:port"

[ivory basalt]

k

[strange brook]

yaml needs to see a string

not a mapping

[ivory basalt]

ok :)

[strange brook]

(or "addr:port", still don't know if it needs brackets`

either way it needs to be valid yaml

a yaml linter would have told you that

regardless of networking or anything else

[zinc sapphire]

yaml bad

[ivory basalt]

maybe so wiz, but I wasn't certain bungee or waterfall can even listen on ipv6. I did quite a bit of searching, and everything I read, albeit older, suggested there was no support at all. So, I asked the basic question

[strange brook]

you asked a general question despite encountering a specific error

this is like a reverse xy problem. you knew exactly what you needed but you asked the wrong question

[zinc sapphire]

wiz wizzzzz wizzzzzzzzzzzzz

[strange brook]

💤

see what i did there

[ivory basalt]

does "bind_local_address" mean all addresses the host has? I was under the impression it was referring to localhost.

also, it's

"[addr]:port"

It accepted my address in that format, but said it was already in use. I'm guessing that's due to bind_local_address being true, but I'd like confirmation if possible.

[reef fulcrum]

Honestly never been in an environment where I could use v6 to toy around with it tbh

[strange brook]

[addr}

[reef fulcrum]

Looks like it tries to force connections to use a specific adaptor or something

[strange brook]

tf is this

[reef fulcrum]

probs means []

[ivory basalt]

typos

sorry :S

[strange brook]

o ok

so what i said in the first place

🙃

[ivory basalt]

fixed

Yes, but sounded like you were uncertain, so I was giving you certainty :)

💙

[strange brook]

i mean, it's standard notation

[ivory basalt]

yeah, but bungee. lol

[strange brook]

bungee isn't a network lib tbf 🙃

i'm assuming they use netty too

[ivory basalt]

no idea. beyond my scope :S
But speaking of scope... I need to head out to see what I can do with about $1200 worth of fried electronics on a demarcation wall :(

[strange brook]

wtf is a demarcation wall

(in context)

[tidal musk]

i remember those days when ipv6 was disabled in bungee

preferIpv4Stack was forced to true

[tidal blade]

I'm sure this is asked a lot so I quickly searched above but couldn't find an answer. Is there some walkthrough documentation for Waterfall? I've got paper sorted but having multiple issues with sorting waterfall.

[deft sierra]

is there a way to disable tab complete of commands for bungeecord?

or a plugin that disables it

[tidal musk]

yes, it's possible with a plugin

or do you mean only bungee commands?

[reef fulcrum]

There is an event on the proxy itself

.g javadocs waterfall ProxyDefineCommandsEvent

[marble kelp]

(DiscordBot) https://papermc.io/javadocs/waterfall/io/github/waterfallmc/waterfall/event/ProxyDefineCommandsEvent.html -- ProxyDefineCommandsEvent (Waterfall 1.14-SNAPSHOT API): "Called when the proxy intercepts the command packet allowing for plugins to prevent commands being added to the clients which might not be wanted."

[reef fulcrum]

And no

The proxy defines the commands itself, only way you can do it is with controlling perms on the proxy

(really, if you're dealing with perms, proooobably wanna be using LP or something that works across the board properly)

no zml, wut

I don't even know what the status of events in terms of tab complete

oh, it works

I mean, we technically could

Yea, it's not

Bungee just fires events in the network pipeline, which is just stupid

[deft sierra]

@tidal musk bungee only commands

I got the spigot side working

But not bungee

So, I'm trying to create a server network. I think i've setup my config correct so far

I'm confused about the last part

so from listeners down

[reef fulcrum]

By default, the only thing you generally wanna change is the host address

typically if you have port 25565 available, you configure the proxy to be on that port

[winged tundra]

what are forced host?

[reef fulcrum]

lets you send people to specific servers based on the hostname

[winged tundra]

ahhh

so I don't really change anything there?

[reef fulcrum]

if you're not using it, leave it

[winged tundra]

ok

Ok, I got this. But is says server is in online mode when trying to connect

[reef fulcrum]

I'd suggest reading the bungee installation instructions

.fw

Oh, we don't have that alias

But, I'd also suggest reading their firewall guide that should be on the page

[winged tundra]

ok, where is the link for this/

[reef fulcrum]

.g bungee installation

[winged tundra]

does the water fall server also need to be set to offline?

[reef fulcrum]

No

[winged tundra]

both my survival and skyblock are set to offline and it still says its online

issue was I was trying to use the bungee server as the lobby?

Is this possible?

[tidal musk]

bungee is only a proxy

u cant host worlds on i

it~

u can just add the hub world to an allready existing server

[hard trench]

https://pastebin.com/Be59SLvt what happeend here?

[tidal musk]

uhh plugin task scheduler is shut down for some reason?

[obtuse flame]

Hello, i got a question about Waterfall. My question is if Waterfall allows players from joining with multiple version like 1.8 to 1.12 ? I don't worked with Waterfall yet and is there any configuration?

[reef fulcrum]

Waterfall explictly, no; you'd need a plugin like the ViaVersion suite

[obtuse flame]

I'll take a look into that thanks for the quick answer 😃

[heady wave]

anyone knows a plugin like premium lock?

[tidal musk]

huh?

[winged tundra]

Is there a plugin that syncs chats across the network?

So example

[SkyBlock] Message
[Survival] Message

[hallow veldt]

@winged tundra ChatControl with bungeebridge

[winged tundra]

oo

So does it show messages from one server on another

and not just join?

Also can you link me what I need please?

[hallow veldt]

.g chatcontrolpro spigot

(see Packet Rules). Bonus 3: ..."

[hallow veldt]

with that + the api it needs u can talk between all the servers

[winged tundra]

and is the global just deafult chat?

or do we need to type a command in front

[hallow veldt]

u can make it default

Im pretty sure

[winged tundra]

can you double check for me before I buy it

[hallow veldt]

u can

Automatically put players into channel when they join

and u just put them into the global channel

ez pz

and dont let people use /channel

to switch to local

[winged tundra]

have you got this working @hallow veldt

I can't get it to work

[hard trench]

transferred files to new host, what does this mean? i adjusted the ip in the config correctly etc http://prntscr.com/or281q

[reef fulcrum]

it means that the backend server didn't respond to the connection

[hard trench]

what are the common causes of this?

like common things i could mess up

[reef fulcrum]

firewall generally

either that or incorrect IP

[hard trench]

any other ideas? we are trying everything and it doesn't work

the servers ping on their own if you add them to server list in mc

[reef fulcrum]

Speak to your host, maybe?

[hard trench]

its a dedicated host

[reef fulcrum]

You mean, everything is on a dedi?

[hard trench]

yup

[reef fulcrum]

If so, your servers should generally be bound to localhost so that you're not exposing the server to the network

[hard trench]

this is my server config

[reef fulcrum]

Yeaaa

Use localhost, don't expose over the network

[hard trench]

just localhost

[reef fulcrum]

many DCs I've been in don't deal with such traffic properly

[hard trench]

with text?

like what do i put in for hub

[reef fulcrum]

You set the server to be on 127.0.0.1, and configure bungee to connect over localhost

[hard trench]

okay i can put 127.0.0.1 in server.properties

and then i put 127.0.0.1:25566

in the bungee config?

[reef fulcrum]

Yes

Are you using ptero actually?

[hard trench]

yes

[reef fulcrum]

That changes stuff slightly then

Basically, you need to configure the servers to listen on the docker0 interface

(that is done in ptero, leave the server ip addresses as the default)

[hard trench]

okay, so what do i change?

[reef fulcrum]

in the panel you need to bind the servers to that interface

[hard trench]

so if i do this i need to keep the ip in the bungee config and server.properties as the actual ip?

[reef fulcrum]

No, leave server.properties alone, you're in docker so stuff works differently

[hard trench]

so leave it empty?

[reef fulcrum]

Yes

[hard trench]

ok got it

[reef fulcrum]

The trick is that we bind everything to the docker0 interface, as docker containers can access that, i.e. the proxy

[hard trench]

even if i delete it it changes itself to server-ip=0.0.0.0 that, is that fine?

[reef fulcrum]

yup

[hard trench]

we got it to a point where you can log in and be in the hub

but when you try to connect to servers you got the error again

and we changed everything like we did for the hub and it doesnt work

[hard trench]

the guy that helped me went to sleep so im on my own trying to figure out how to make it work

[hard trench]

can anyone help me out? Using pterodactyl panel and im new to it

omg i fixed it myself

[frosty fractal]

Hello! Just changed to waterfall

IT seems like the proxy istn starting

I only have waterfaal-290.jar on the proxy server

[frail brook]

define "isn't starting"?

does it output anything?

[frosty fractal]

@frail brook I got it fixed

Had to rename it "Server.jar"

Hmmm. If I have My server asti waterfall do I need to set The subservers to Paper or Spigot?

[hallow veldt]

Can be any

[frosty fractal]

@hallow veldt what do you recommend?

[hallow veldt]

Paper ofc

Paper behind waterfall

[frosty fractal]

@hallow veldt where can I find paper 1.8.8 or 1.8.9

[hallow veldt]

https://papermc.io/api/v1/paper/1.8.9/latest/download

[frosty fractal]

invalid link

[hallow veldt]

https://papermc.io/api/v1/paper/1.8.8/latest/download

[tidal musk]

Any antibots solutions with Waterfall?

[hallow veldt]

i guessed top of my head

Bot Sentry

.g Spigot bot sentry

[reef fulcrum]

egg82 also has an anti vpn plugin, really, just don't use offline mode and pray 🤷

[frosty fractal]

Do you recommend the hub being 1.8 or 1.12.2?

@hallow veldt

[hard trench]

just linked my domain to my new host, it pings in server list but gives this error when i try to connect http://prntscr.com/or8y8m

[hallow veldt]

Yea Egg has a good free one but bot sentry is "better" I guess? Has more features and stuff
and whatever your playing on yhteys lmao

[frosty fractal]

Hey?

@hallow veldt yea. but just wondering should I make it 1.8 with viaversion or 1.12.2 with Viaversion,Viarewind;viabackwards?

[hard trench]

1.8.8 for sure

older versions usually work better then the new ones

you dont need the new features for a hub

[frosty fractal]

okay, but that link HexedHero sent me

Ingame it says vanilla server

[hallow veldt]

?

[frosty fractal]

Idk if its glitched or what

[hallow veldt]

where does it say vanilla

if its on the server list dont listen to it

[frosty fractal]

On f3

[hallow veldt]

oh

u havent installed it then prob

do /paper

[frosty fractal]

Unknow command

But in the server files theres paper.yml

and plugins folder

etc

[hallow veldt]

ah

prob an effect from being behind waterfall

[frosty fractal]

Its not connected to waterfall

😄

Its just a seperate server

now

HMM

still plugins work

it just says Vanilla server

Time to confuse some peopl

[hallow veldt]

ah yea

Mine says vanilla too

guess its just old minecraft/paper/spigot

[frosty fractal]

lol

[reef fulcrum]

1.8.8

[frosty fractal]

Yes

[sand steppe]

1.8.8

[reef fulcrum]

You're not going to get much support for that here

/paper command is also fairly new

(not new, but not that old)

[frosty fractal]

Just making the hub 1.8.8

[hallow veldt]

wait

so

what versions are u making ur servers?

ur subs

[frosty fractal]

Hub 1.8.8, Survival 1.14.4, kitpvp 1.8.8

[hallow veldt]

ah makes sense

[frosty fractal]

via ViaVersion

[hallow veldt]

why isnt there a 1.8.9 paper?

[frosty fractal]

Only downside is that 1.8 has only few decoration blocks compared to 1.12.2 etc

[reef fulcrum]

because there was never a 1.8.9 server

[frosty fractal]

MAke one

[hallow veldt]

Ah

Yhteys, you could just go all out and make them all 1.14 and on the pvp one add no hitdelay LUL

[reef fulcrum]

oh god not that plugin

[hallow veldt]

im trying to move hiim cat

shh

https://www.spigotmc.org/resources/✦-deluxecombat-✦-ultimate-powerful-combat-resource-for-every-server.63970/ is good tho

[reef fulcrum]

Seriously, that plugin is a :S

[frosty fractal]

NAH

people use 1.8

mostly

[reef fulcrum]

Anybody who is happy competing on a server running plugins like that was just a sheepless moron

[frosty fractal]

for pvp

[hallow veldt]

ur a :S cat

whatever it means

[reef fulcrum]

It only fixes part of the issues

Tweaking the pvp in 1.9+ can make it nicer, tbh

But there are other behavioral changes which at least for me, just dull pvp even futher than just the fact that I'm bad at it

[hallow veldt]

I love new combat, better than holding W and spam clicking

[frosty fractal]

Water looks so gay in 1.8

[hallow veldt]

Its actually so fun on cubecraft for example

[frosty fractal]

https://www.papermc.com/

wowowow

[hallow veldt]

Mojang should seriously just add a "old-combat" setting

ez fix

[frosty fractal]

wait

I had some issues with chunk loading on paper 1.14.3

few weeks ago

they loaded so slowly compared to spigot 1.14.3

Ummm

Theres spigot.yml and paper.yml

wuut?

[brazen sparrow]

spigot.yml is for settings inherited from spigot

paper.yml is for paper-specific settings

paper extends spigot

[obtuse flame]

Do I need OnlyProxyJoin with Waterfall or is there now the function to change it in the configuration?

I do not want anyone to join the servers except the Waterfall Server

[reef fulcrum]

ideally, firewall or if on the same machine, use the loopback interface/docker0 if using ptero or anything like that

Beyond that, for paper servers, use bungeeguard, those proxy join plugins are often broken

[obtuse flame]

And how the players can connect to the server if players are for example clicking on a sign

When the port is blocked?

[reef fulcrum]

They're connected to the proxy

obviously you need to let the proxy connect to the servers themselves

[obtuse flame]

k thanks

[merry field]

Could I keep a server offline until someone joins?

Through waterfall

[tidal musk]

kinda

definitely if you write your own solution

i can imagine writing a smaller proxy what accepts tcp connection, boots up the server and then passes the connection to it

works fine with backend servers as ip address is passed using bungee's ip forward data anyway

[bold stirrup]

Hi! Waterfall docs?

https://papermc.io/forums/t/explanation-to-waterfall-yml/1040/3 or still down? 😦

[hard trench]

Can you make network-compression-threshold -1 on everything (proxy + spigot servers) if your servers are all on one machine

Or just spigot

[heady wave]

anyone can help me fixing this?
https://timings.aikar.co/?id=9864c4c697d24e82bf188d3dad4e9f02#timings

[hard trench]

cause bungee is taking a fair bit of cpu i dont know if its normal or but but if someone could answer that it would be great ^

not the timings guy my question c:

[oblique hound]

should I use the recommended GC flags for Paper for Waterfall?
as in the same start.sh script

[reef fulcrum]

The recommended flags should work fine

[tidal musk]

yo

so

i run an anarchy server

and i have a queue

and an asshole keeps crashing the proxy by joining ALOT of bots

like he makes then rejoin all at once and shit

how can i fix it

like im talking 300 to 400 bots

what happens is the bots join right then the proxy just times out

how can i prevent it from doing that

[quartz jetty]

Anyone know a tiny plugin that sets the max players to XXXX/1

just figured it might exist before i code it

[lean zenith]

@tidal musk thought of getting an antibot?

@quartz jetty Probably ServerListPlus or many out there that do that

[quartz jetty]

I just need a plugin that has only that feature

[tidal musk]

@lean zenith

which one

[lean zenith]

Any

Botsentry, ABD, Linus's AntiBot

They all do the same thing

[tidal musk]

bloody fuck

[tidal musk]

yo

@lean zenith i got bot sentry

and the proxy still crashes

[tidal musk]

https://pastebin.com/00LDtaFp

thats wat it does

[lean zenith]

Got atleast 1GB of RAM on proxy?

[tidal musk]

b ro i gave it 4 gigs

[lean zenith]

I can be hit with 4000 bots and doesnt affect performance

thats with ABD

who knows what botsentry is like

[tidal musk]

i have botsentry

https://pastebin.com/yBCP4PDJ

[lean zenith]

then possibly the reason, let the author know about it

some setting that may be out of place

[tidal musk]

it happened before i had it to

[lean zenith]

Jeez, well im unsure how i've deflected all mine

[tidal musk]

the plugin does whats its suppost to do

the bots basically all login at once

it times out soon as they do

[tidal musk]

23:39:20 [WARNING] Event PreLoginEvent(cancelled=false, cancelReasonComponents=null, connection=[Aeixn] <-> InitialHandler) took 10,006,432,314ns to process!

[lusty badger]

i think it is caused by another plugin

not bot sentry

[tidal musk]

yeah i figured it out

it was having all the player perms in the bungee config

and not with a proper plugin

[dusty gyro]

Hi! Does a installation guide for Waterfall exist?

[hallow veldt]

its the same as bungee

google bungee setup guides

[dusty gyro]

Sweet, sounds good. - and just so I'm sure. Waterfall is it's own thing, correct? If I install Waterfall, I should uninstall Bungee?

[reef fulcrum]

Yup, waterfall replaces bungee

[dusty gyro]

Awesome, thanks for the info! Appreciate it 😄

[obtuse flame]

Is there a way to get the current server a player is on it? I tried that with p.getServer().getInfo().getName() but somehow it returns null

[hard trench]

@obtuse flame probably should ask in waterfall dev

[obtuse flame]

oops

[hard trench]

Can you make network-compression-threshold -1 on everything (proxy + spigot servers) if your servers are all on one machine?

[hallow veldt]

Anyone know how you can or even if its possible to have a server behind waterfall but have both servers online-mode true ?

[tulip fossil]

Why do you want backend server to be in online-mode? People should not be connecting to it directly

[hallow veldt]

So it doesn't use offline uuids?

and not if u put the ip to localhost :/

[tulip fossil]

It should be using online UUIDs if you set online_mode: true and ip_forward: true in Bungee config, and bungeecord: true in Spigot config

Do you have it set up like that currently?

[tidal musk]

is there a way to have a modded server that requires client-side files up and a vanilla spigot server up and able to be connected between at the same time?

[cyan dove]

online_mode has to be set to false if you wanna use bungeecord

[hallow veldt]

Any idea why 172.18.0.1 is my localhost IP on bungee to connect to my server? not 172.0.0.1 which is what the server binds to?

[reef fulcrum]

because docker

[hallow veldt]

Ah

[dense knot]

Can I somehow disable ServerListPing protocol? I want to disable anyone seeing info of my waterfall instance.

[teal robin]

In that case, turn it off, or just change the values from the event to something meaningless

[topaz escarp]

is there a wiki for me to follow?

Use the bungeecord wiki, nothing really changes in that aspect

okay so i fixed that problem but now im confused on how you set up the listener/query port. in the config.yml are you supposed to put the port of the server for the query_port and host?

oh i have query disabled so the query port doesnt matter, but what should i put for the host then?

this is the error when i keep running it

[16:13:49 WARN]: Could not bind to host /0.0.0.0:25577
java.net.BindException: Address already in use: bind

[marble kelp]

That one means that something is already running on that port, probably a stray server

[grizzled root]

thats what i thought, but nothing is.

what should the host line in the listeners section of the config.yml be

the port of the server thats running?

[marble kelp]

no, the port that you want bungee itself to listen on

[grizzled root]

so by what do you mean when you say listen? because thats what i thought it meant

oh my mistake, i had accidentally clicked waterfall.jar so it was running on that port, i have that fixed but now it just says listening on that port

how do i actually connect that to my server

[hard trench]

You can turn off network compression threshold on spigot servers if you have bungee but can you turn it off on bungee as well if its all on one machine?

[grizzled root]

i fixed it, so im connected but now im having trouble putting multiple servers on

its saying this

okay, is it the names of the worlds?

because when i had it named lobby it was fine but as soon as i tried to put the other world it stopped working

do you just add another world like this

[reef fulcrum]

it's more you broke the yaml formatting than anything else

[grizzled root]

ok, how do i fix it

[reef fulcrum]

I can't see your config file

[reef fulcrum]

use pastebin or something

or use a yaml linter

[grizzled root]

https://pastebin.com/KADHTmrA

[reef fulcrum]

(Basically, somewhere before line 43 you formatted it improperly

[grizzled root]

huh, okay, ig now i just have to find where. by the way, thank you for your help! you didnt happen to see anything in that pastebin that looked wrong did you?

[hard trench]

rip me asking the same question for 3 days and being lost in all the messages

[reef fulcrum]

Oh, last line after

Your other server is intended with 3 lines instead of 2

[grizzled root]

wow.

what a dumb mistake

haha im sorry, it can be kind of hard to see and i hate how yaml needs spaces not tabs

[hard trench]

You can turn off network compression threshold on spigot servers if you have bungee but can you turn it off on bungee as well if its all on one machine?

[reef fulcrum]

Pretty sure that's already been answered

Yes, you can

But, there is generally no reason to do so

[hard trench]

Oh, well are there some negative effects?

cause the bungee is using a decent amount of cpu

[reef fulcrum]

It's a tradeoff between cpu usage and bandwidth

[hard trench]

so if we have a 10gbps port

then its fine?

[reef fulcrum]

There is a lot more to networking than the size of your port

No point you having a 10Gbps port if your clients are on shitty DSL

ideally, compression would be more dynamic to the network conditions

[grizzled root]

hey, i got it all fixed but im getting an error trying to switch between servers

[17:03:07 ERROR]: [BoundlessVirus|/127.0.0.1:58235] <-> ServerConnector [Duel-TNT] - encountered exception: net.md_5.bungee.util.QuietException: Unexpected packet received during server login process!
1ac7017b227472616e736c617465223a

[hard trench]

i guess ill just increase the value for now and see how it goes from there

[reef fulcrum]

something sent a bad packet

[grizzled root]

how do i troubleshoot that

it happened for me and all my other players

something misconfigured maybe?

[reef fulcrum]

start pulling plugins from the server

[grizzled root]

that server is just vanilla

i just set it up

[pastel ocean]

Hello! I noticed something very weird on my network, sometimes when a player connected to one of the backend server disconnects this happens:

[17:03:28] [Netty Worker IO Thread #58/INFO]: [...|rageboy7] -> UpstreamBridge has disconnected
[17:03:29] [Netty Worker IO Thread #58/INFO]: [...|rageboy7] <-> DownstreamBridge <-> [Pixelmon] has disconnected
[17:03:29] [Netty Worker IO Thread #58/INFO]: [rageboy7|...] <-> ServerConnector [Hub3] has connected
[17:03:29] [Netty Worker IO Thread #58/WARN]: No client connected for pending server!
[17:03:29] [Netty Worker IO Thread #58/INFO]: [rageboy7|...] <-> ServerConnector [Hub3] has disconnected

basically when the client disconnects the player is connected to the main lobby

but as expected waterfall detects no players connected for the pending downstream connection and closes it

isn't this a bit weird? :/

[pastel ocean]

How can i try to debug this?

[marble kelp]

you'd need to work out what is causing it to jump them to a new server when they disconnect

[pastel ocean]

i checked every plugin i have running on the proxy, none of them appears handle disconnecting players

is it possible that the PlayerKickEvent is called even with disconnecting players?

[reef fulcrum]

I'd imagine not

[cedar quiver]

@grizzled root If you mess up your yaml format again try using: https://www.freecodeformat.com/yaml-validator.php - it works decently

[pastel ocean]

@reef fulcrum PlayerKickEvent is called on player disconnection! 😱

wtf

let me try with an empty waterfall instance

PlayerDisconnectEvent -> ServerKickEvent -> ServerDisconnectEvent

let me try with bungeecord

Yep it is a Waterfall bug

[tidal musk]

[pastel ocean]

Bungee only calls PlayerDisconnectEvent -> ServerDisconnectEvent

lel

Seems like https://github.com/PaperMC/Waterfall/blob/86ec79b6a537b1e04c09909860a1693e12d473de/BungeeCord-Patches/0028-Improve-ServerKickEvent.patch changed the ServerKickEvent behaviour

but i think the event shouldn't be called when the upstream is disconnected normally

[reef fulcrum]

Ahhhh, lets pretend I didn't forget about that one

[pastel ocean]

AHAHAHAHAHAH

[reef fulcrum]

Reaaally that shoulda been handled in a seperate event :/

[pastel ocean]

This should be fixed, really, it caused a lot glitches on my network

[reef fulcrum]

Best fix I've got would basically break plugins expecting that event to work as it does in waterfall

No idea what the heck you'd call the event

[pastel ocean]

just make it configurable and deprecate the waterfall methods

[reef fulcrum]

That's not really a fix

I mean, I guess we could

[pastel ocean]

i don't see any other compromise

[reef fulcrum]

It's just gross

But really, that patch is gross

[pastel ocean]

the patch was gross

oh lol you ninjed me

just remove that behaviour in 1.15

keep it deprecated in 1.14

this patch breaks the normal api behaviour, doing mothing is the worst solution

[pastel ocean]

so what's the plan?

[reef fulcrum]

Do you know what cause it fires? Guessing it's the lost_connection one or?

[pastel ocean]

@reef fulcrum exactly

are you copying mineplex's messages

[manic agate]

With the latest WF (build293) I still have the issue (as mentioned about 12 hours ago) that WF is trying to connect me to the hub when I actually disconnected entirely. (I didn't read the changelog so I had hoped that this would be solved)

[next bloom]

Hi there, anyone able to tell me please, how/where can we change the Waterfall server list string?
The part that says Waterfall 1.8.x - 1.14.x

[marble kelp]

Use a plugin for it.

Try https://www.spigotmc.org/resources/wrongversion-1-7-1-14.42070/

[next bloom]

That looks like its only changing MOTD, but thank you

[marble kelp]

It's not?

Or.. well.. yes..

[next bloom]

Oh nvm, I see you can also modify version

Thanks alot

[marble kelp]

But it does give people information though.

[next bloom]

Did exactly what I needed, thanks again

[radiant ruin]

I have right permissions but

still not able to use /server

  - bungeecord.command.server
  - bungeecord.command.list
  admin:
  - bungeecord.command.alert
  - bungeecord.command.end
  - bungeecord.command.ip
  - bungeecord.command.reload```

[marble kelp]

Do you use any permissionplugins at all?

If not, you may want to install LuckPerms.

Having issues lately with travertine, the fork of waterfalll
same issue occurs with waterfalll
https://gyazo.com/ec9235d35f8b5542d7509f71480c882a

certain players willll drop their connection to the server when they're onlline
after a whille they'llll be able to rejoin again
no errors in bungee or anything
just this:

  - bungeecord.command.alert
  - bungeecord.command.end

  - bungeecord.command.reload
``` I use luckperms

[tidal musk]

then those permissions are irrelevant

you must add those permissions to players/groups in luckperms

/lpb group default permission set bungeecord.command.server true

[radiant ruin]

ok

Thank you

[tidal musk]

that's correct

[supple fulcrum]

Is there any way I can have players switch between proxies?

[unreal stag]

Nope, and you should really only use multiple proxies for redundancy/scalability, not partitioning your network

[marble kelp]

Is https://www.spigotmc.org/resources/redisbungee.13494/ what you would be using for having multiple proxies?

If you have that plugin + Redis, what happens if one BungeeCord goes down?

[supple fulcrum]

What is the max paper instances I can put under waterfall? For example can I put 1000 paper instances under one waterfall instance?

[marble kelp]

There is a limit on how many players you can have under one Waterfall instance. This is based on your cpu.

[supple fulcrum]

That makes sense, but I could just scale up in the cloud whenever I reach that limit

[marble kelp]

I've read if you have over 700-1000 players, you may want to expand with another proxy.

[supple fulcrum]

Right okay

[reef fulcrum]

if a bungee instances goes down, everybody connected to that will go down

[marble kelp]

So it's not possible moving them to another proxy?

[reef fulcrum]

No

The client doesn't have a way to tell it to connect somewhere else

[marble kelp]

I get TheRealLemon question. It sounds like a nice feature.

[supple fulcrum]

Yeah although it does sound nice, it would probably be messy with some kind of proxy before a proxy, which is a terrible idea.

I am just brainstorming my new MC Network idea and I need better understanding of scalability 🙂

[unreal stag]

If you're already thinking multi-proxy you probably need to tone down your ambitions.

[strange brook]

smh people thinking they can be the next hypixel

[marble kelp]

Is Redis and RedisBungee a good way for splitting the amount of users over several physical servers?

If the hardware isn't good enough to handle the amount of users.

Or is it better to just have some Paper servers on one physical server and some on another one?

[haughty nimbus]

wiz let's create hypixel's clone?

[strange brook]

let's call it RoastDuck

[haughty nimbus]

No let's call it WeebJany

[night bobcat]

Any help would be appreciated:
https://github.com/PaperMC/Waterfall/issues/420

[reef fulcrum]

The only spikes in there are when you take a snapshot

[night bobcat]

It takes snapshot when CPU reach 80% or more usage. Otherwise I can't take snapshot because YourKit says connection terminated or lost before it can capture data.

I can provide more snapshot. This one is a softer one but you can still see the spike in 1h48m:
https://www.dropbox.com/s/tot2etbmdwdoh2t/BungeeCord-2019-08-18(9).snapshot?dl=0

[hard trench]

That issue number 😏

[winged tundra]

Does anyone know how I can get essentials placeholders to work in a bungee chat plugin?

[marble kelp]

Essentials has placeholders? 🤔

[winged tundra]

I mean for nicknames

[marble kelp]

if Essentials sets the nicknames correctly then you might be able to just use the Displayname instead of the username in your chat plugin

[winged tundra]

globalChat: "%fullname% %displayname% &7>> %message%"

so I use that, and they both return the username

I can see my nicknames are working though

[marble kelp]

what does the tab list show? the username or nickname?

[winged tundra]

username

anyone?

[celest tide]

Hi, can a bungeecoord plugin listen for player death events?

[haughty nimbus]

No

I mean you could hack something together with plugin messages but not sure why would you want it though

[celest tide]

I am making a plugin that works as a discord bot to allow users to chat with other users on discord

Like DiscordSRV but for bungeecoord

@haughty nimbus

[high mason]

bungee doesn't get death events, you could make the plugin work on bungee and server and install it on all servers and just have those be responsible of sending the death event

[haughty nimbus]

well you can send plugin message to bungeecord then

[high mason]

oh right, that's probably easier 😛

[dense knot]

Does anyone know how to disable ServerListPing with firewall? Some services such as mcsrvstat.us use that to show info about the server.

It's this "ping" thing here.

[haughty nimbus]

hmm you probably can blacklist it via plugin and maybe blacklist port 25565 to certain ip addreses. Not sure why would you want to do that though

[tidal musk]

It's bungee that just drops their connection

[reef fulcrum]

Read timed out means that the proxy wasn't sent anything in so long

[tidal musk]

I know that but that wouldn't make any sense, could it be the firewalls ?

[reef fulcrum]

if your firewall starts dropping packets, could be

[tidal musk]

hm, we use two mitigations to run our network

using 2 redis servers

I don't know if that could trigger it too

my sysadmin can say with 100% assurance that it isn't his firewall @reef fulcrum

[reef fulcrum]

Please don't ping me

[tidal musk]

Eh k?

[reef fulcrum]

1. It's annoying 2) I have bad eyes so it's harder to read

You can configure the timeout there in config.yml

[tidal musk]

we're using this;

log_pings: false
connection_throttle_limit: 9999999
prevent_proxy_connections: false
timeout: 30000

30k should be enough I think xd

[tidal musk]

timeout on 60000 fixed it

thanks electro

for (ProxiedPlayer player : BungeeCord.getInstance().getPlayers()) {
   player.sendMessage(new TextComponent("Hello world"));

any way to do this better?

acutally that is not even working

BungeeCord.getInstance().getPlayers(), is not working in "onEnabl"

[reef fulcrum]

Well, yea

There will be no players online at that point

I have a thing registering a socket there, so there will be aftera while

[boreal thunder]

is there a way to change the world name on waterfall? like on gametracker it shows the world name as "waterfall_proxy"

[tidal musk]

by patching the source

it's hardcoded iirc

[scenic pebble]

Gametracker? O.o

[tidal musk]

oh no, i'm wrong

you don't need to patch the source

you can modify it via ProxyQueryEvent by using setWorldName in ProxyQueryEvent#getResult()

[upbeat ember]

whats gametracker

[hard moat]

@upbeat ember its a game server list site

Anyone know why I get this error?

I have a subdomain forwarding to the ip : 51.81.13.56, but I can't see how to fix this issue :/

I've tried using the direct IP, gives me the same erro

Anyone? 😕

[marble kelp]

are you sure that's your server's IP?

[hardy vale]

Wdym?

My bungee ip is : 51.81.13.56:25565

I have the subdomain : play.townyorigins.com forwarding that IP

But it doesn't want to bind and idk why

[marble kelp]

is the port open/free?

[hardy vale]

Yeah supposed too?

It's default port

I haven't used it anywhere else and it worked before

[marble kelp]

does the address show up if you run ifconfig on that machine?

also try using netstat to check if the port is actually available or used by a different process

@acoustic adder

[marble kelp]

yeah, the address you mentioned previously is not your server's public address

[hasty lagoon]

Does anyone know of a plugin to use portals to move between servers? I've tried a couple that are meant for BungeeCord and they don't seem to work with Waterfall

Never mind, I'm an idiot and missed a step setting it up >.<

[clever valley]

@hasty lagoon i joined this discord just to ask the same question, what did you do to fix it?

i've tried iPortals and bPortals but neither worked whatsoever

[marble kelp]

Janus works just fine ¯_(ツ)_/¯

[hasty lagoon]

@clever valley I ended up using iPortal, the mistake I was making is after you create it you have to use the setto command to tell it what server to go to, you can't include it in the create command

[clever valley]

@hasty lagoon oh jeez i made the exact same mistake

thank you so much.

[hasty lagoon]

Hah, no problem! That's hilarious, glad I could help

[marble kelp]

seems dump to not allow that in the create command lol

*dumb

[clever valley]

yeah a little unintuitive

[hasty lagoon]

Agreed... Part of the documentation implies that it should work, and the command doesn't error out if you try to include it, the destination just doesn't get set

[marble kelp]

I should just add cross-server support to Multiverse-Portals 🤔

[hasty lagoon]

That would be cool

I was a surprised at how difficult it was to find a way to get portals working at all, seems like a pretty common feature on multi-servers

[reef fulcrum]

bungeeportals probably still works 😄

[hasty lagoon]

Possibly, I couldn't find anything saying that it works under 1.14 though

[marble kelp]

simple plugins usually don't need updates between minecraft versions, that's the whole point of having an API

[hardy vale]

Any ideas why players get Connection Throttled, please try again later, oftenly?

Hi, im trying to run FTB with waterfall and paper-clip. I can join my server with FTB launcher and switch between server but i cant join FTB-server /server ftb, only error i get is from waterfall:

[04:34:43 INFO]: [roxer01|/15.4.175.67:60963] <-> ServerConnector [ftb] has connected
[04:34:43 INFO]: [roxer01|/15.4.175.67:60963] <-> ServerConnector [ftb] has disconnected

what could be wrong?

[obsidian cape]

hello

how i translate bungee messages?

just extract messages.properties ?

[tidal musk]

this is waterfall...

[obsidian cape]

yeah but messages are bungee

lol

let's call proxy then

[hallow veldt]

edit the messages file in your jar

[obsidian cape]

ah into jar

[reef fulcrum]

messages.properties is the supported way, yes

[tidal musk]

Do i need something more otherwise waterfall, paper-clip och FTB-server to run a FTB-server so ppl can join through my lobby?

[reef fulcrum]

did you try the metadata setting I said?

[tidal musk]

where did you type that? (kinda tired, been uo for 35h now)

Sorry for being annoying

[reef fulcrum]

I don't recall, a while ago

[tidal musk]

on irc or here in this channel?

[reef fulcrum]

Just open waterfall.yml and disable entity metadata rewriting

[tidal musk]

disable_entity_metadata_rewrite: false

its set to false

[reef fulcrum]

set it to true

[tidal musk]

okey

and then restart?

[reef fulcrum]

yup

[tidal musk]

i will start up ftb, will take 5-10 min

Now when i tried to join the server i got this messeage: Failed to login: Invalid session. (Try restarting your game and the launcher)

I´ll try to restart the game

Now im in the launcher. Im in the multiplayer menu. Its a X after the server in the list. When i hold the mouse over it, it says: Incompatible FML Modded server 0 mods present

[tidal musk]

I can join but get kicked out in the same sec

[deft sierra]

Is it possible to hide servers from /server ?

Like restricted servers can't be seen

I can't seem to reload server config for server ip

I needed to restart for it to work

[tidal musk]

dont give all perms for /glist

[obsidian cape]

so i i can just extract message file on waterfall directory? or i need to edit the jar?

[tidal musk]

extract, yes

[austere pebble]

Is waterfall a direct drop in replacement for bungeecord?

Would need to know what the actual kick was

incompat fml is expected given the whole "connecting to vanilla"

[tidal musk]

the only thing i get in error message is this from waterfall:

[reef fulcrum]

Erm, if you want

Be warned that it does open an abuse path

[tidal musk]

Is it known wide?

[reef fulcrum]

Kinda, not sure people generally care to take advantage of it given that it's limited in most servers

[tidal musk]

Should i add the flag to waterfall as well?

[reef fulcrum]

No

[tidal musk]

Okey

I appreciate your help and time

Need I add the flag on the FTB-server?

[reef fulcrum]

no

[tidal musk]

Ok

[reef fulcrum]

yup

I¨ve only added the flag to my survival world

Now i can connect to my survival world but i cant join FTB

Log from waterfall:
[20:43:13 INFO]: [roxer01|/15.4.175.67:62778] <-> ServerConnector [ftb] has connected
[20:43:13 INFO]: [roxer01|/15.4.175.67:62778] <-> ServerConnector [ftb] has disconnected

[reef fulcrum]

waterfall log is irrelevant

[tidal musk]

Okey

[reef fulcrum]

What's important is who is closing the connection and why

ServerConnector disconnecting would imply that the target server was just "nope"

[tidal musk]

Nothing in the FTB console

Im out of ideas

Im useing the latest build of this plugin if i matters:
https://www.spigotmc.org/resources/protocolsupport.7201/

I can only work with what I can see
