Yeah, btw #waterfall-dev would probably be a better channel
Fallback system is extending a plugin I don't think you can do that
Only 1 class should extend Plugin
rough warren
stiff nova
ok sry for the wrong channel and then I did misunderstand the extend
but it worked everytime
lime breach
It would be weird if it worked 
stiff nova
i swear it worked xd
lime breach
If you need access to the Plugin methods you can just create a static Plugin variable in your BSS class and initialize it on enable, or just create a getInstance method idk. There are a lot of ways (some are not recommended).
stiff nova
did it like this
lime breach
I see some errors

ok then i post this in #waterfall-dev and you could help me 🙂

does anyone know of a plugin to spoof my server brand i don't want people knowing it's paper and waterfall

🤦♀️ why? They will still be able to know if it bungee or normal server

What is waterfall supposed to do ???
I use paperMC but I don´t know what waterfall is.
reef fulcrum
waterfall is a fork of bungeecord which is a server proxy for jumping across servers
cold notch
waterfall = bungeecord
humble prawn
Is ist different to paperMC ?
humble prawn
A proxy is normally for a connection
cold notch
waterfall = router that connect all pc together in this case pc = minecraft server
humble prawn
It´s for more than one server, right ?
reef fulcrum
Basically, yes
It's a proxy, it lets you move between between individual servers vs having everybody on a single server
humble prawn
And there is also travertine that i never heard before
cold notch
travertine for tyhose ppl that wanna use to support 1.7

Bye!

okay, Im really confused on what I am doing wrong. I am using waterfall as my proxy and paper as my server. I have the absolutely most up-to-date jar files, and I have all of the server config files set right, but I cannot get the player ips to forward. The skins load, but the paper server claims all users are joining from the actual server ip address. Any help would be greatly appreciated!!!

Anyone ever had this error?:

Heyo guys, Im having some trouble setting up waterfall.
Im trying to get it to run on SpongeForge on my modpack server, but im not sure where its sending any config files, and none of the commands in the console like are registering as valid commands
reef fulcrum
er
waterfall is a proxy
config files for the proxy will be in whatever folder you ran the proxy in
individual servers, etc, still work as individual servers

Hi all, I have some questions regarding Waterfall + PaperMC and connecting to a Forge (FTB Revelation) server. I currently have everything hosted on a dedicated server, and am trying to connect all my servers through Waterfall. I have Waterfall + the Hub/Lobby and another vanilla PaperMC world working perfectly fine, but I cannot access the Forge world via /server [server] no matter what I try. Below I'll list exactly what my current setup looks like.
Hub
FTBRev
Pixelmon (currently just a clone of Hub for testing /server joining)```
That's the structure so far. I can connect to the Hub world through both vanilla clients and Forge modded clients (which took me researching to find a fix through the git, which required me to add the java argument "-Dpaper.disableChannelLimit=true" to the run.sh) with no issue. I can use /glist to see other players, I can use /server to list servers accessible, I can use all commands a normal player can. When running the Pixelmon server (again, clone of Hub), I can use /server Pixelmon and it will successfully transfer me to that server.
The problem comes in when I try to join the FTBRev server through Waterfall/Hub. I am using FTB Revelation 3.2.0 Server pack (downloaded directly from the FTB Launcher), and the 3.2.0 client modpack (again downloaded via FTB Launcher) to connect. Connection to the Hub works fine; all the commands above work the same. Trying to switch to FTBRev using /server FTBRev does not work. No message is posted into the in-game console, but when I look at my consoles for Waterfall and FTBRev, I get these two results:Waterfall
[01:01:41] [Netty Worker IO Thread #1/INFO]: [Korinthian90|/71.61.24.69:50975] <-> ServerConnector [FTBRev] has disconnected```
**FTBRev**
```[01:01:41] [Netty Epoll Server IO #1/INFO] [neid]: Patching class: "net.minecraft.network.play.server.SPacketBlockAction" with Transformer Group: "TransformerGroupBlockHardcoredConstants"```
Here are the (almost) full logs from Waterfall and FTB Revelation:
Waterfall: https://pastebin.com/tThWjVxn
FTB Revelation: https://pastebin.com/D4P02sus (the full log was too large to put in pastebin, so I grabbed the section after the world goes live, and down to the Netty Epoll entry)
Here are the configs for both servers as well:
Waterfall: https://pastebin.com/Di6ELNGY
FTB Revelation: https://pastebin.com/21reJnZy
I feel like I'm missing something very basic, but I can't for the life of me figure out what it is. Apologies if this is the wrong place to ask (since the issue seems to be the Forge server), but I'm pretty fresh to this kind of stuff and didn't know where else to turn. Thanks in advance for any support!try connecting directly to the forge server instead of going through a lobby
some mod (packs) seem to have issues when not directly connecting to a forge server
zenith blade
I have connected to the sever directly (turned it back to online_mode=true) and it works connecting directly to it. But I'd really like to use the Lobby to transfer people there; if it's not possible, though, is there a way to force Waterfall to connect Forge users directly to the Forge server instead of to the main Hub/Lobby?
Basically just wanting to have 1 IP/port that people need to add as a server,. and have Waterfall take care of the rest. I'd hate to have to set up the FTB Revelation server as its own thing separate from Waterfall and the Hub.
marble kelpBOT
I mean connecting directly to it through your proxy
either by using a plugin or a forced host setting
if you really want a lobby then you might have some luck setting up a second one for your modpack users using a modded server
zenith blade
Could you expand on the forced_host part a little bit? I'm trying to understand how exactly I'd set that up, and I'm looking at the config, but I'm not entirely sure how to go about writing it in. This came default in the config
pvp.md-5.net: pvp```
I imagine I would another entry there with [host]: FTBRev based on my naming, but in the host section - would I put [serverIP]:[port that FTBRev is on]?hostname is what the user types into the box on the client
server name is what's in the config for that server

Is there some sort of parameter that can help with high memory usage? Uptime of 24 hours and my memory is almost at 100% on my proxy due to constant connections (possible attack) but just wanting to know if there is some sort of parameter to help in a way?
lean zenith
Alright, so some sort of GC flag can possibly help take off the memory usage overtime?
strange brook
and like...if you think something is spamming connections you should probably look at fixing the cause instead of trying to fix the symptoms
lean zenith
Just a simple bot attack on the network at times, and constant connections of legit players joining.

manic agate
Is there some technical explaination of the disable_entity_metadata_rewrite function? I want to know the possible interaction between this and tablist functionality.
reef fulcrum
disabling that basically resends a join packet to the client, making it act as if it's joining a new server and refreshes lots of entity state, etc
relevance there is that likely the plugin relies on us not refreshing all of that client data
manic agate
Sounds like it can't hurt to turn it into true. Does it also refresh/clear scoreboard teams ?
reef fulcrum
yes
at least, pretty sure it does
It resets a lot of the clients state due to the nature of what the packet does on the client
manic agate
Ok, thanks for that. The problem I'm facing is that somehow 1 player got himself on top of the tab list despite sorting by the tab plugin which does not even make use of the scoreboard. No errors what so ever. Still figuring out what might have happened.

Why waterfall (java process with 400m) needs that much of cpu 🤔
reef fulcrum
it's a proxy pooping packets around
beyond that, really boils down to what you've got installed on it
use a sampler or something

It changed a field in the login success packet from being a string with hyphens to being a fixed length int array
reef fulcrum
if you're actually dev'ing yourself, you need to change how you read that field based on the protocol version
old depot
I know
protocol/src/main/java/net/md_5/bungee/protocol/packet/LoginSuccess.java
would it be there?
I'm trying to fix it but I'm not sure how
I know I need to change something from an string to an int array
reef fulcrum
go look at how they read it it vanilla?
Probs just some bit shifting to move the things into place, not looked
reef fulcrum
there are projects like yarn which map the server
old depot
they track protocol changes
reef fulcrum
I'm familiar with the site
reef fulcrum
Without looking at source, best I can do is piss in the wind to guess the impl of what's needed
old depot
this field contains the UUID as a string with hyphens a fixed length int array
you're saying that's not enough info to make a fix?
reef fulcrum
no
Once again
Best I can do is take a piss into the wind as opposed to their impl
old depot
it's gonna be hours if I try to get yarn working and find the right class and everything
😐
it's just one simple change
the array will have 4 entries
the 1st part, the 2nd part, the 3rd part, and the 4th part of the uuid
edgy snow
Dunno if this would be helpful for you or not
reef fulcrum
is that a picture for ants?

Pretty sure this was extracted from the server code with yarn mappings. Don't remember where I found this tho

is that in 20w12a?

It was from when they first introduced the new uuid changes to be an int array

use some logic
uuid can be packed as 2 longs
msb and lsb
now you also take msb and lsb from those two longs
and bam
you have two integers
err four i mean
reverse the logic
you'll have uuid

wdym metadata handling?
I updated the uuid format in LoginSuccess

twin egret
Anyone ever come across a reasonable way to send commands to other servers under waterfall (1.15.2)? Ie. run command on server A and have it passed on to server B?
upbeat ember
redis
marble kelpBOT
lots of different way to do that in a plugin or even just a log reading script xD
marble kelpBOT
redis offers both, a key value storage that can be used like a database as well as a pub-sub-messaging system
unless you already have redis running you'll want to just use a dedicated messaging system though
twin egret
am I understanding correctly that the process is essentially sending the command to an external db then somehow the other server knows to pull the command out and run it?
marble kelpBOT
no, you use a messaging system. continously checking a database would be wasted time and energy
twin egret
That's what I figured 😅 I think this is likely over my head currently! I assume there isn't anything more straight forward? Not against setting up a redis db but I'm mostly surprised there isn't something out there that just does this and nothing else (it seems like redisbungee does a bunch of other things?)
marble kelpBOT
I'm pretty sure there are tons of plugins already made with that goal using different methods
twin egret
Oh, is there something I should be looking for then? Everything I've found is either very old, sounds sketchy or is just more confused people asking the same question lol
marble kelpBOT
old doesn't mean non-working. the api didn't really change there
beyond that I can't really tell you what to look for. I tend to make these kind of plugins myself xD
twin egret
oh, that makes sense, I just assume everything changes every version ;-;
Really what I would love is a generic way to pass any command between servers. Started with wanting to be able to send rewards to a survival server from a pvp server, but would be nice to be able to handle announcements and other simple commands (without writing something custom for them all, you know?)
at any rate, thank you kind suspicious bot/human hybrid!!

Started getting some issues on my server, probably not related to bungee but it's network related? 🤔
Basically every 10-20 min, the server will suddenly be unable to contact the database (hosted on another machine)
Coreprotect: java.net.ConnectException: Network is unreachable
Litebans: java.sql.SQLTransientConnectionException: litebans-pool - Connection is not available, request timed out after 30000ms.
Caused by: java.net.SocketTimeoutException: Read timed out
And it will freeze the server for a good amount of time, everyone gets kicked to lobby ofcourse and then it goes back to normal again.
I haven't changed anything with the database or firewall lately, just started happening
covert portal
So a long time ago I noticed that some configurations of Bungee/Waterfall + ViaVersion would make the player "instantly" join, without any other plugins.
But now Five made a proxy that support snapshots and the "bug" resurfaced, but this time with no Via on Bungee.
If anyone has any idea why this happens and if it could be integrated into actually Waterfall that would be nice:

please help
lime breach
you probably did some yaml syntax errors in your bungeecord config
lime breach
send your entire config
spiral plume
spiral plume
what line
lime breach
yeah I noticed that's the error
spiral plume
lime breach
that has nothing to do with the config issues
tidal musk
something is clearly wrong on your side, perhaps misconfiguration?
spiral plume
with the server?
lime breach
isn't the ip on port :11111?
lime breach
... it seems like you haven't read any bungeecord documentation at all anyway
tidal musk
to use a proxy, you must always connect through it
spiral plume
tidal musk
wrong viper, it isn't configured by query port
lime breach
?
tidal musk
the address(es) where proxy will listen will be determined by listeners[n].host option
spiral plume
english?
lime breach
yeah my bad, they were the same anyway
spiral plume
i can send u my spigot server config as well idk what ive done wrong
lime breach
is the proxy on a VPS/Dedicated server?
spiral plume
im hosting it all locally
tidal musk
still seems like you've not gone through the documentation properly
idk, am off for now
spiral plume
please i need this up today
lime breach
lol
spiral plume
should proxy protocal be true
lime breach
its function is explained in the doc.
its not something you'd want to change usually
spiral plume
Description: This allows the server to support the HAProxy PROXY protocol. Most users shouldn't need to enable this
tf does that mean
spiral plume
so the port that i connect to is query or host
tidal musk
host
marble kelpBOT
(DiscordBot) https://en.wikipedia.org/wiki/0.0.0.0 -- 0.0.0.0 - Wikipedia: "In the Internet Protocol Version 4, the address 0.0.0.0 is a non-routable meta-address used to designate an invalid, unknown or non-applicable target."
lime breach
are people trying to access your localhost proxy from outside ?
spiral plume
i want other people from other countries to be able to connect
lime breach
not a good idea, anyway you might want to configure your router's firewall
lime breach
are you connecting from the same machine the server is hosted on?
spiral plume
yes for testing
lime breach
lol then use local addreess
lime breach
Im sorry I have to go now,
lime breach
do not ping dude...
lime breach
you can literally setup join priorities from the config

ye it goes to lobby

if you need quick help then put up a request on spigot forums and for some money someone might configure everything for you over idk teamviewer or something
lime breach
where did you get that emoji mikroskeem
reef fulcrum
if there is nothing in the proxy logs, you're not connecting to the proxy
either that or you're having issues with your firewall setup, etc
spiral plume
how do i connect the proxy
reef fulcrum
connect to the proxies IP/port like you'd connect to any other server
spiral plume
i am
host: 0.0.0.0:11111 query port: 11111 address: 127.0.0.1:25565
and on the spigot the ip = 127.0.0.1 and port is 25565
reef fulcrum
if you're connecting to the :11111 address in your client, god knows
that falls into network setup issues
spiral plume
surely not as im connecting to 127.0.0.1:11111
so it cant be firewall
what's the next step
spiral plume
want my config?
reef fulcrum
no, nothing to do with your config
reef fulcrum
This is basically not a waterfall issue at this point
best advice would be maybe check the client logs
spiral plume
ill try another client
on blc it just does this https://i.imgur.com/K8nH7wX.png
instantly
also it doesnt ping either
i think i found it https://i.imgur.com/h39LB6a.png
is that like AV firewall?
i disabled it and now it just goes back to disconeccted again
lime breach
I didn't have any issue when self hosting from a small dedi I had at home running Kubuntu, pretty sure this is not a waterfall issue
lime breach
spiral plume
nope not that eaither
lime breach
The firewall should not matter if you're making local connection from the same machine
spiral plume
ill just try restart my pc
nope
anyone want to ss me this is really annoying now
do i need a host server?
[13:24:02 WARN]: Forced host server pvp is not defined

that's not an issue

i cant see any issue. no errors ts so ANNOYING

how am i supposed to know what "anticrash" solution you need?
telling people here that some kid is crashing your network says literally nothing
it's not like there's only one way to overload a proxy, am i right?

But I was told you need an anticrash

what is an anticrash even?
what do you expect it to do?
magically solve your problem?

olive needle
Hello, I'm having an issue. I set up a waterfall network today morning and since then I have users experiencing high ping on only one end of the server.
Let's say I have a lobby server and a survival server, each one on a different PC on the same network. Their IPs would be:
Hub server: 192.168.0.10 (Here is where Waterfall would be running)
Survival Server: 192.168.0.8
strange brook
those are the same ip tho
olive needle
Edited I have autism
Thing is, back in the day they would connect directly to my 0.8 IP through the 25565 port, but now that port is running on the .10 address, for waterfall to work
However players on the survival (.8 server) are experiencing lag issues when most of them didn't. I am pretty new to this waterfall thing, so I'm pretty much clueless on what to do
Both computers are connected to the same switch
olive needle
Exactly. On some cases chunks won't load for a couple.
lime breach
ok so you have a proxy machine, and the "game" servers are attached to it via an etherne cable, so we're assuming there's no delay between them ? Correct me if i didn't understand correctly
olive needle
There's just two machines
One host the proxy server AND the hub
The other hosts the survival server
olive needle
Update: I have specific users that can't even join the survival game server
lime breach
Mhh are you sure that the machines are communicating correctly between each other?
olive needle
yes. I am inside the same network as the machines, and I've got zero ping. I've also got a couple of users with absolutely no issues (I believe)
It's just a couple of users
I have a question. What is the purpose of the IP-forward section of the config? Is there a way in which I can handle everything WITHOUT the IP forward?
olive needle
On bungecoord's config
There's an ip-forward true
or false, whatever you set it to. I have the belief that I'm putting a lot of load on the proxy by allowing the IP forward to happen
Well, more than the proxy, my network.
Could it be a possibility?
tidal musk
tldr version of the chat above: you're experiencing a lag
and you
you're thinking that ip-forward is the cause?
nah
ip-forwarding option passes extra and perhaps even useful data to backend server
such as player's actual ip address and their profile (skin data)
it's done once and using handshake packet

I know I shouldn't use it, but it's a one time thing
tidal musk
no it won't
reef fulcrum
That's the ping passthrough
If you want a global player count, you need that disabled
vast tundra
is this also a drop-and-replace for bungeecord?
evidently not because it gets stuck(?) on [15:49:43 INFO]: Enabled plugin cmd_send version git:cmd_send:1.15-SNAPSHOT:87d2873:326 by WaterfallMC
ruh roh now even bungee wont load
nvm it worked after about 2 mins
actually it was a plugin, not even waterfall, disregard
probably the firewall

hi its possible crash waterfall with netty exploits?
im getting attacks with proxies ping and the proxy seems crash
lime breach
you're getting botted?
tidal musk
netty exploits?
are there RCEs, buffer overflows or other stuff around for recent netty versions now?

I am in the process of setting up 4 servers with waterfall and ,...so far... it's working. However, there are some errors in the console. Since I'm new to Waterfall I'm not sure if I should be concerned about these errors. These errors don't seem to have any impact on the players connecting and getting to the other servers. I found a couple links talking about this error, but the conversation wasn't very helpful. So, posting here.
Waterfall Server Errors:

It's the Waterfall Server Console.

i have my server down since 2 days
i am receibing around 10 or 20k connections for second
i think that are proxies
the thing is each connection send empty packets and crash the bungeecord
anyone cant connect and the server no respond to the ping
the proxy ips are infinites i think
it was day and night since 2 days

.firewall
Anyone have a link to setting up firewall so I don't have to use IpWhitelist? Think I did it wrong cause now I can't even connect to my bungee.

high mason
Ended up figuring it out, but thanks 🙂
mighty cloud
im using firewall from ovh network and ubuntu firewall with ufw system to protect the trafic input and outup
the thing is that are massive connections from different ips sendind empty packets that overload my network and anyone cannot connect
its impossible to blacklist ips because are 50k every second
marble kelpBOT
start dopping the IPs in your firewall, seeing as it has been going on for 2days now I doubt that they haven't had tons of repeats by now
mighty cloud
in the firewall i only setup open 25565 with ratelimit to 10 connections every second
but are proxyes and this setup do nothing
marble kelpBOT
(the more difficult solution would be to put some kind of packet filtering proxy in front which drops connectiosn sending that packet directly without having your bungee/mc server being influenced by the filtering)
mighty cloud
i dont have any way to filter packets by size, ovh dont offers me filter packeting by size and anyway in the configuration only offers that control traffic redistrubited by their net
marble kelpBOT
I mean if you had such a thing setup you wouldn't have the problem xD
mighty cloud
i have been set up to 50 or more iptables to drop connections but also do nothing the massive ping is broken the player connection
reef fulcrum
any piece of software can only handle so many connections opening
either you look into tryna use the firewall, or look into other mitigation options, e.g. mitigation services such as tcpshield or load balancing, or you close the server 🤷♂️
welcome to the joys of running a server
marble kelpBOT
also just so you know: depending on your jurisdiction ddosing a server might be a crime so if you have and indication on who is doing that contact your police's cyber crime department
*any indication

It's --nogui, and you don't need it for waterfall
lime breach
Do you think one day Mojang will allow for IPv6 connections?
marble kelpBOT
I'm pretty sure they do
tidal musk
they allow ipv6 connections
but they disable ipv6 AAAA record resolving
since ipv6 is more broken than you can expect
ending up with 30-60sec connection delays because how broken dns/gateway is in some places

looks like something mangled the chat component in a kick packet
tidal musk
ii there documentation for how to set up waterfall?
or do i just follow bungeecord documentation
lime breach
basically yes
twin egret
anyone have any docs for setting up bungee/waterfall where not all servers are on the same machine? I'm just about ready to add a second machine to my little network but can't seem to find anything 😅
tidal musk
the server IPs in the config are just the IPs of the external servers, and if they arent on the same machine then make sure to use something like bungeeguard to prevent access to your backend servers @twin egret https://github.com/lucko/BungeeGuard
twin egret
is there anything on the networking side I should consider to keep things locked down though? I'm already using bungeeguard but that seems too easy! lol
tidal musk
bungeeguard is the networking protection, assuming you cant firewall the ports because its not on the same machine
twin egret
alright, I'll give it a shot, thank you!
severe atlas
@twin egret or use wireguard to setup secure vpn between your servers
strange brook
unless you're really paranoid about traffic getting sniffed or something
you're trying to prevent external traffic, not encrypt everything between your servers
twin egret
mostly just worried about the standard issues for a waterfall network, nothing too intense (yet, I hope)!
severe atlas
I have a question regarding waterfall. I'd like to fully understand what it does, how to implement plugin for it and for example how to setup servers in way that I connect only to "lobby server" there I need to login and on other servers I'd already be loggen in. Another issue is that if I'd join to "lobby server" and switch server I'm brand new player on that server and is not aware that I logged into "lobby" I'd like lobby server to be only entrypoint. So I'd been thinking abount solution to my login problem and got that: If there is any method to intercept incomming (direct connect/ connecting by server list) connection to waterfall (not between respective servers) then tp player to lobby server where player will be forced to login. And that other problem I dont have any idea. Sorry for my bad english. Generaly speaking I'd like to learn whole waterfall flow and stuff

Waterfall is a proxy, it what players connect to when they want to connect to your paper/vanilla/spigot, etc, minecraft servers. The config files allow you to specify which server people connect to
severe atlas
Thanks, can someone @here give opinion aboout my idea to resolve issue with login
severe atlas
Sorry
I have another issue, I know that probably is somewhere there but I ask. When I'm reconnecting to server, every time I am a new player and get kit, welcome message and all that stuff
Do I need to iptable something
Or config?
shrewd shard
Hello guys, i'm having an issue with waterfall, when we are connected, on the same forge server VIA the proxy waterfall, we don't see each other (players being invisible). Is it a known issue, a config thing ? 
plush delta
Hey, stupid question: is there any sort of documentation/install guide on how to set up waterfall? do I just follow the bungee guide but use a different jar?
plush delta
ok, figured that out. now is there a way to make all of this (2 servers + waterfall) start when my computer starts up?
marble kelpBOT
use whatever autostart functionality your OS offers?
plush delta
bungee recommended using screen so I could still access the server console
do y'all prefer that or RCON
marble kelpBOT
I doubt anyone uses rcon
plush delta
so screen? or something else im missing
reef fulcrum
rcon works, but it's not really suitable for actual administation, more automation/running the odd command here and there
marble kelpBOT
most probably use screen or tmux
(if they don't use some other kind of administration/management tool like a web panel or something)
reef fulcrum
one day I'll get autostart working
My current trick is that I just literally never restart
marble kelpBOT
I only restart if I a) crash linux or b) move to a different server xD
so yeah, I don't auto start anything either, lol

nightlies where basically dead, but, it ran, kinda
did end up having to pull in some patches manually which was fun
tidal musk
also speaking of sysadminning
i made a schema in dhall for one json configuration
just to ensure shit is safe
and have sane defaults
ebin
so basically i have git repo full of configs for every process ever i need to manage, values not present are coming from schema 👌

I currently have a server setup with SpongeForge and Waterfall. I'm having an issue where projectiles (splash potions, snowballs, etc) can hit players in spectator. Anyone know a fix to this?
marble kelpBOT
I doubt it has anything to do with waterfall
