might be a backdoor or you simply having the server query enabled without a password

hoary osprey
could you elaborate on "server query enabled without a password"
marble kelpBOT
minecraft supports a query protocol which allows executing commands
.g minecraft wiki query
(phoenix616) https://minecraft.gamepedia.com/Minecraft_Wiki
oof
actually that's the wrong one, I don't think that one supports commands
this is what I was thinking of: https://wiki.vg/RCON
marble kelpBOT
well make sure that it is, then check all your plugins for backdoor code I guess
and if you discover one redownload all plugins and server jars from trusted sources and check them for the previously found code to make sure they don't include
(I would start by searching for where that port was opened)
hoary osprey
alright, thank you
hoary osprey
after some time and asking around
im told that it's an uncommon luckperms exploit that happens when someone is able to run waterfall commands from backend servers
and i quote:
"so you need to disable the ability to run waterfall commands from in-game
what they are doing is accessing luckperms via the waterfall server
there's a waterfall config item that prevents people from executing waterfall commands from the minecraft servers"
marble kelpBOT
waterfall doesn't have such an option, they are most likely talking about a plugin adding that functionality

What version are you running? Waterfall and on your servers What plugins have you got? Etc... We need more info than just a log dump.
Also read this https://github.com/SpigotMC/BungeeCord/issues/2806
Your issue is more likely a DDoS attack rather than a waterfall issue

steady wharf
what benefits has waterfall vs bungeecord?
reef fulcrum
we have various performance tweaks over bungeecord, a bit more API and have improvements to make the proxy more robust
steady wharf
okay, thanks. is there any wiki to check the full comparision?
reef fulcrum
No, the patches are on github, however
steady wharf
cool thank you cat!
steady wharf
are waterfall servers just accessible with a Forge launcher?
reef fulcrum
waterfall is a proxy, not a server, it supports forge 1.12.2 and below, modern forge all hopes of compat as-is essentialyl
steady wharf
i want to use waterfall as a proxy for paper (not forge) servers
or i must use normal bungeecord to do that?
reef fulcrum
That's not from waterfall
steady wharf
oh my bad

Is there a way to make forced_hosts work with restricted?
Like if you try to join a certain server through the forced_host setting and you don't have the permission for that you get sent back?
sent back = that the normal priorities list applies
royal hawk
Quick look at the code tells me that you shouldn’t be able to do this without plugins
But with plugins it should be quite possible
nocturne trench
But with plugins it should be quite possible
Du you happen to know one?

From the admincraft discord:
I am on last version of waterfall, all my 1.8 to 1.12 servers are not working
For example, I have a 1.8.8 papermc server connected to the bungee, when a player tries to join with a 1.8.8 client they get disconnected with that console error
GenesisIIX lost connection: Internal Exception: io.netty.handler.codec.DecoderException: The received string length is longer than maximum allowed (30 > 20)
Im getting this error even with a clean server install without any mods or plugins
And when connecting directly without going thru bungee, it works fine
I did my own research and found that the only part of the minecraft protocol that requires a string with a length of 20 chars or less is the Server ID in the Encryption Request packet https://wiki.vg/Protocol#Encryption_Request
Would that have anything to do with this bug?
The protocol doc describes the Server ID field as being "unused" but does third-party server software like Bungee/Waterfall use it?
royal hawk
@undone carbon No, that would require a length limit to be in place here on Waterfall, which it is not.
Also side note
Encryption is only bungee <-> client
Is this error from the bungeecord or the backend server?
undone carbon
backend server
royal hawk
Then I would assume that this is the arbitrary plugin channel identifier/name length limit md_5 imposed back in the day youre stumbling upon
let me check that
rugged acorn
Hey there, so Its my error if you have questions qou can ask me directly it would be easier, @undone carbon was trying to help us hahah 😄
undone carbon
btw, i was doing support for @rugged acorn; i'll let him take it from here
rugged acorn
Thanks again man :))
undone carbon
ye
royal hawk
well checked and the message then is more to the tune of Attempted to send a Plugin Message to a channel that was too large. The maximum length a channel may be is 20 chars.
wait
need to check the other side again
rugged acorn
You mean a bungee plugin right?
rugged acorn
No problemo 😄 ty XD
reef fulcrum
enable debug in server.properties iirc if you want useful messages
royal hawk
that much is true too
rugged acorn
Ok debug is enabled, server is restarting, well see
royal hawk
So yes, this has to be a CustomPayload or plugin channel name
since the server is in offline mode it cant be the encryption
reef fulcrum
wrong direction for that packet anyways
reef fulcrum
encoder vs decoder and the location of the message are importanté
rugged acorn
Im getting this with debug https://pastebin.com/MzVhRwYm
reef fulcrum
So, yea, some plugin message
rugged acorn
Youre saying the problem comes from a bungee plugin?
royal hawk
either that or from a client mod
rugged acorn
Cant be client mod im testing it myself
reef fulcrum
royal hawk
well do you have a custom payload or plugin channel registered?
reef fulcrum
they're using via
reef fulcrum
It's more the protocol hack aspect of it
rugged acorn
Well nice
reef fulcrum
You have a plugin on the proxy which is
- Seeing a newer version of the protocol, so assumes the newer limits
- using an older version of the server software which has a limit on the length of the channel names in there
rugged acorn
I mean, I couldnt ask for better support 😄
royal hawk
I would assume its #1
reef fulcrum
it's 1 and 2, it's assuming newer limits and pooping itself coz the server itself doesn't allow that
rugged acorn
On bungee we dont have much plugins, only the "official" recognized one
reef fulcrum
installing via on the proxy might be more compat but is not the ideal setup
rugged acorn
Yeah thats what i have been told
reef fulcrum
otherwise, you'll have to find out what plugin it is and "prettyplz" the author
royal hawk
Well its not beyond people to change the limit on that old version of spigot either
rugged acorn
Ok so I will try on a staging Bungee to see if I can target which plugin or even reproduce the error and Ill keep you guys informed, thanks for the support,
(I will also try to install via on bungee, whch one ahould I installl?)

This is using travertine btw
reef fulcrum
I get a feeling that's from the client
little garden
Luckily this is for an app, so its used to generate codes (think of how namemc does website linking)
maybe I can switch it to offline mode then kick out non authenticated players with a custom message?
reef fulcrum
what I mean is, that that error was 100% on the client side, it didn't even manage to actually connect to the server
did you mess up the auth process 🤷♂️
little garden
Nah, its all online mode at the moment. Theres a plugin that runs on the LoginEvent (i think) sends a post request yada and kicks the client with a message
But if that message is client side... My only option is to set the proxy to offline mode and manage auth myself and kick with a custom message

why cant i join a server? so im in the lobby and im op. i added a queue plugin to connect to my main server. so it works fine but i cant bypass the queue. would this be on the plugin? or the server not recognising i can bypass player cap?
bold swan
I would imagine that would be down to the plugin's permissions
Oh wait you just added the proxy didn't you? Proxy plugin permissions are going to be handled differently
kind jungle
huh?
i have literally no idea what im doing
i got 2 servers, one lobby for the queue and the main one
it directs players to the lobby and auto places them into a queue (using ajqueue)

done all that

ok so my genius plan failed
why is it if i sudo a player to /server it doesnt work

Connection reset means that something external to the proxy closed the connection in an unexpected manner

Player player = Iterables.getFirst(Bukkit.getOnlinePlayers(), null);

at the moment seems to be only sending it to a single player

Iirc you'll need to tie it into something like BungeeChat

Why don't you do /alert or /alertraw in bungee console

covert island
Hey sorry, but is there any way to get the waterfall performance improvement as well as the flamecord protection?
bold swan
Your best bet on protection is going to be a properly configured set-up (such as firewalling). That being said, if you aren't relying on any Bungee plugins, you may want to take a look at Velocity, as it has its own set of improvements/performance boosts (and is well-regarded in the community). The biggest downside is not having access to Bungeecord plugins (although Velocity has its own set of plugins)
reef fulcrum
If people can provide info on stuff, we can look into it, however, most of what flamecord adds is a leaky firewall
covert island
so basically flamecord is a fake or it actually does something?
reef fulcrum
Basically, their software is a closed source rip of waterfall, they've added a few tweaks to it, one of which waterfall already has but in a much more refined way, beyond that, the only real of-standing thing that I've seen is their firewall, which is basically a huge ass memory leak
royal hawk
I’ve already got two more mitigations lined up that I am going to PR later today if all works out
reef fulcrum
I mean. not too much, really
disable query, firewall off the IP, work out where that connection is coming from and speak to them, could be some service you signed up to borked or was misconfigured or something
left finch
disable query, firewall off the IP, work out where that connection is coming fro...
whenever i try to disable query ( while server is turned off ) it turns back on, so i guess the company is automatically enabling it for it's own reasons?

Hey guys - we have a new server running on a 3900x (3.8 ghz) with 32gb memory (64 for server itself) on US East Coast- we notice tps drops as low as 17. Running 20-30 people on it. Would this be a good candidate for Waterfall? Can waterfall be placed in other geo regions like Europe for example or are they best placed in the same dc?
royal hawk
Waterfall is a proxy to link multiple servers together. Ideally a proxy is close to the servers, because the distance and relative lag from the client to the proxy and then to the server has to be taken into account. Possibly making two round trips over the world; to the proxy and from there back somewhere else is less favourable
stuck gazelle
linking how exactly? I doubt it can support the same survival world?
stuck gazelle
oh I did delete there yes - figured it would be a better question in here
royal hawk
No, you connect individual servers to a proxy. They don't communicate with each other
if you want to build a network with for example a factions and a minigames server then a proxy is right for you
stuck gazelle
thats what I figured ok - was hoping to use waterfall to maybe take some of the connection strain off the main SMP box but not the right fit
marble kelpBOT
yea doesn't change overall bandwidth
royal hawk
Well youre relaying the same load by using a proxy
marble kelpBOT
just where the front doors are
tps drops to 17 is like nothing, but otherwise check your /timings paste
royal hawk
and we should add, modern minecraft versions can be very heavy on the host system even if you have the most balling specs

Hello, I have a Waterfall server and I added two servers. When I log into Bungeecord, it does not redirect me to the main server, it redirects to the other server, and this causes a security vulnerability in my server. I've only experienced this on my own OP account. Other users are connecting to the main server.
royal hawk
That sounds suspicously like an offline-mode proxy; we don't support that. Secondly, are you sure you enabled force-default server?
reef fulcrum
the proxy stores the server the player was last on
reef fulcrum
are you using mods?
grim glade
how can i fix?
reef fulcrum
try without plugins, if it is them, you'd need to work out which one
royal hawk
You can fix it by disabling entity meta rewriting too
That setting is in the waterfall.yml
reef fulcrum
depends on if it's a mangled packet or just a bug in entity metadata rewriting, I mean, I doubt, but, wouldn't be unheard of
grim glade
but what do meta entities do?
reef fulcrum
players are entities too

I believe it is viaversion, every time a player enters from a metadata error

Hello I have a question is it possible to create timings for bungeecord and how long would it be possible to create or program something like this =?
reef fulcrum
No, use a sampler, bungee is threaded, timings is not designed for that
snow harbor
But if someone tried to create something like that, how long could it take?
This information is really important and more when you have many attacks or a large amount of public
Would it also be possible to do something like this with a plugin or is it not possible?
reef fulcrum
Basically, timings is designed for something which ticks, bungee doesn't
there is no concept of a loop to monitor, so, outside of tryna hardcode a time frame, it's generally gonna be meh on the outset
not to mention, you'd have to make timings able to monitor multiple threads
snow harbor
I get it and see the consumption of the plugins that use the ups and downs of CPU and Ram when you receive x number of users or an attack also not possible?
It seems that using bungeecord has its limitations

Is there a 1.16 alternative to this?
Unless this feature is built-in to paper and I'm not aware 😄
reef fulcrum
wrong channel, and plugins like that generaly don't break assuming they're built well
silk umbra
does waterfall come with any built in viaversion like system?
royal hawk
No; but Waterfall supports 1.8-1.16.5 natively like bungeecord, it doesn’t translate however

Hi Guys!
I have two problems with waterfall
The first is that when a player joins the CPU used by the waterfall it jumps from 5% to 90/100% (I state that the cpu is an i9 9900k) even without plugins
The second problem is that when there are many nearby users (such as an arena or a waiting lobby) the cpu used reaches even 700% until the players move away from each other.
I do events for my subscribers on twitch, and this happens when there are already more than 50 players nearby, as soon as they get to about 100/150 waterfall it saturates all the cpu.
Could anyone help me? Even in private chat 🙂
royal hawk
Run spark when you’re under that kind of load
Report back when you have that ready
Additionally, is there any kind of indication in the logs that you are being attacked? Might also happen in the background
Going even further; if you don’t need waterfall/bungeecord for its plugins consider checking out velocity
I’m open if you want to shoot me a DM
royal hawk
?
I just don't have DMs open for anyone 
this can be fixed by turning off entity meta rewriting and tab list rewriting
waterfall.yml
The java $env and the java $home shouldn't matter as long as the process is privileged for the appropriate IO/sockets. Also that error message doesnt say anything, the crucial part of it is missing
... okay so I looked at it and Bungeecord trims the important part
nice
I assume the proxy has no way to connect to the server its trying to put you on
if the server is on the same host as the proxy ensure loopback traffic is unrestricted if youre using 127.0.0.1:port or if youre using docker or another container solution; ensure that those ports are appropriately forwarded and you adhere to their networking
now I'm getting confused
This error: io.netty.channel.AbstractChannel$AnnotatedConnectException
-> Cause: Your proxy (Waterfall) can't connect to the server you're trying to go onto
Fix: Resolve your networking or firewall issue
This error: https://srcb.in/rhGuJas1kN
-> Cause: Bungeecords rewriter
Fix: waterfall.yml
disable_tab_list_rewrite: true
disable_entity_metadata_rewrite: true
If your issue is fixed now then thats good I guess

Nope, the server and players internet are fine
Pining the server is fine, it only happens inside the server

I'm checking to see if it might be caused by my anitvpn

I'm checking to see if it might be caused by my anitvpn
Unlikely tho
And btw why don’t you allow people to use VPN
normal sinew
It prevents bots
harsh vigil
Actually it will
normal sinew
and alt accounts
harsh vigil
Fair enough
But it couldn’t block all the vpn IP address
Cuz it’s not cleaver enough
normal sinew
Yeah I know it wont do all
harsh vigil
Maybe it will just detect the ASN and some popular VPN’s IP address
normal sinew
Could this issue be a tab complete thing? I just tried to do /gm3 /gm1 /gm3 /gm1 really fast and my ping shot up
harsh vigil
How many Ram do you have in server
normal sinew
On my proxy there is 1gb
normal sinew
i9-9900k
harsh vigil
1GB isn’t decent but I believe it won’t cause the issue
How many players r in the server?
How many plugins did you install?
How many cores did you enable for the server?
normal sinew
There is like 60 plugins on my server, I can still trigger this lag with only a few players
I have a dedi with 4 cores I think
Although I'm looking at the status page and the proxy server's ram looks like its capping
harsh vigil
try to move your server to one of your another computer with higher storage of rams
Test it again
To see if the issue still exist
royal hawk
Just chiming in here; you do have compression disabled from server-proxy right?
normal sinew
network_compression_threshold: 256
royal hawk
Also 1G is more than enough for well over 100 people
normal sinew
is that what you are talking about? Should that be -1?
royal hawk
@harsh vigil the default is 512m and it’s plenty. Per player you’ll be using less than ~3 megabytes per player. Where it gets hard is plugins
royal hawk
Also for networks compression should either be disabled or higher
normal sinew
setting it to -1 did not work
royal hawk
512 or 1024 at max
normal sinew
I can cause this ping spike by simply going back and forth betwen gamemode survival and gamemode creative
royal hawk
Well for one even if the server takes a hit it will remain at 20tps. Ping spike as in server-proxy or proxy-player?
The second one shouldn’t ever be an issue because the proxy does keepalive ping separately from the servers
normal sinew
It's like proxy-player, it will randomly select some peope to lag out when I create the lag by going back and forth
royal hawk
Now here is where it gets interesting
The Tablist shows what the server reflects
And the server either knows the real player ping through forwarding
Or it doesn’t
normal sinew
So I can spam /ping and it be just fine, I did a MTR and it looked fine as well
royal hawk
So when you say ping do you mean actual delays or just that it shows a low connection in the Tablist
On paper servers the command handlers are detached form world ticks so any fired commands will work regardless of other network states; same is true for bungeecord
normal sinew
i can do the /ping command and there wont be any ping spikes. I do any kind of teleporting, changing gamemode and ping will skyrocket
let me do a screen grab
normal sinew
So when you say ping do you mean actual delays or just that it shows a low conne...
my ping is 100 to the server, I go back and forth between creative and spectator mode and then I get this ping spike. This will also randomly impact the pings of others. No one in this example though. I can consistently make this happen.
past raven
Can anyone help me setup a bungeecord server?
tidal musk
-_-
harsh vigil
do you know whats the command to test the time latency?
past raven
no
reef fulcrum
mesing with compression ain't gonna fix the latency values
in general, mc's measurement of latency is not just measuring network latency but also how well the client itself is performing
normal sinew
On proxy startup it takes this long for luckperms to connect to mysql [LuckPerms]: Successfully enabled. (took 6007ms)
reef fulcrum
it's expected to sky rocket when doing things which essentially cause the client to stall in some manner, joining servers, switching works, etc
normal sinew
what about changing from creative to spectator
reef fulcrum
that shouldn't induce anything afaik
normal sinew
I can 100% consistently cause ping spikes for me and random members by going back and forth between creative and spectator with 20tps
reef fulcrum
tps is 100% unrelated to the keepalive stuff
normal sinew
I do want to loop this post back in because its pretty much the same issue https://www.reddit.com/r/admincraft/comments/l44urj/atrociously_high_ping_issues/

Is there good documentation for Waterfall somewhere? If there is it eludes me.
reef fulcrum
most of the documentation is generally covered by bungee
torn socket
Right, after doing config and having everything setup I'll connect to the server, nothing loads in, the proxy boots me, and then I wait 30 seconds before getting ejected.
From what I've read this is a VPS issue with some providers, and I'm hesitant toward going with a minecraft host as they're typically horrifically overpriced. Does anyone know of a VPS based in the USA, preferably east coast, that can actually work?
royal hawk
Explain your setup in greater detail; I can’t make heads or tails of this
torn socket
Right.
So, I use serverspace.io for the VM, it has 6 cores, 16GB of RAM, and a fast enough connection, the issue I see with Waterfall (it also happens on Velocity) is that somehow their network configuration is a little off and it times my players out when they join, it's dependent on ping, since the US players can get in and everyone else can't.
I've tested all configurations on my personal server, no issue there. It's only with a cloud hosted VM.
And since the project aims for 7 pixelmon maps, I'm reluctant at best to actually buy 7 servers, each of which will be $30 USD a month, at that stage it's smarter to buy a US based server.
As far as the software goes? Spongeforge 2854, Waterfall 395, most recent MySQL, no mods or plugins active for testing in any configurations.

mild rover
There would be, if the vanish plugin had an api
if so, just intercept serverping, remove vanished players and ur done

You'd need some form of plugin for it which would somehow need to sync the state from the server itself

2 second ctrl-f of the page shows they have bungee support already
you'd need to speak to the plugin author, we can't provide support around premium plugins

I think I talked to him once and he said something like
"Unfortunately there is no support for server queries. It's the server or bungee itself that sends it and there is no API for me to interact with."

aa ok abd packets exploits from clients are fixed?
That strongly depends on what kind of exploits you are referring to. Whatever affects the proxy or integrity of the servers behind the proxy we tend to cater to. We do not fix bugs in ingame mechanics with Waterfall
marble kelpBOT
the biggest servers probably run their own software/forks

But velocity can’t run bungee plugins?

well yes, it cant. But big networks usually code their own plugins anyway. Besides there are alternative plugins for a wide range of bungee plugins for velocity

And how to fix bot attacks? What do u preffer?

Bot attacks is something networks normally don’t have to worry about. A good ban plugin should do the trick there. Bots are nearly exclusively a problem with offline mode server/networks and those aren’t supported by paper or the wider community.

real wraith
DoS exploit going around where they connect 40-100k proxies from foreign country's with no intention on completing the handshake. Best fix is to block the whole subnet/range from joining either through your hosts firewall, or through IPTables. Just an FYI
Russia: https://www.ipdeny.com/ipblocks/data/countries/ru.zone
China: http://www.ipdeny.com/ipblocks/data/countries/cn.zone
Can't be blocked efficiently through Bungee, and somewhat bypasses OVH's anti-DDoS. GL all
royal hawk
@real wraith see https://github.com/PaperMC/Waterfall/pull/603
should already be mitigated
real wraith
@royal hawk Nope. It stops one of the exploits though which was spamming tons of crap to the server
royal hawk
If you have something else to report that needs fixing, post an issue on github
just saying nope doesnt help anyone @real wraith
real wraith
What could they possibly do from layer 7?
reef fulcrum
The biggest thing is gonna be the logger and the general typical # of connections in play
real wraith
The connection just stalls. Zero data. It times out
royal hawk
that sounds like a typical DoS
reef fulcrum
You can reduce the logging, but, then you kill the ability for people to be able to monitor stuff in general
royal hawk
a DoS is not an exploit- its a given for any network application
real wraith
Most proxies I've seen in ages though. Seems fully blocked by just dropping some of his ranges
reef fulcrum
Only real good fix for stuff like that is blackholing ranges or basically using a connection limiter on the firewall to try to tame the damage of new connections
real wraith
FivePB chill out. DoS is an exploit. It literally means denial of service. Exploiting something to cause disruption of service to normal users
reef fulcrum
people use the word 'exploit' too liberally
real wraith
Yeah. It seems mostly from China and RU. I blocked only around ~10 ranges on a friend's server and it seems too weak to cause any issues now
reef fulcrum
sure, it's exploiting the typical nature of the internet, but, to call it an exploit per-sei somewhat implies that it's taking advantage of some bug or something
real wraith
Well it's taking advantage of your machine's inability to handle that many connections at once. Therefor exploiting the application's inability
🤷♂️
Call it what you want, I don't give a fuck. Just spreading the word so people don't get fucked over
royal hawk
Even if your application can hold the onslaught, youre straining your own connection possibly to the fullest so you end up unreachable anyway

If the server they’re on crashes they get kicked. If you don’t want that then you’ll need a plugin to change that

@ zzzCat would you accept a fix PR that does hotswapping of scoreboards if the issue arises?
reef fulcrum
the issue is the state desync it induces
you fix the proxy from screaming but you totally botch the state
reef fulcrum
the issue is that the client still has the old scoreboard
best I got as a fix would be to basically queue up the scoreboard packets until after we've cleared off that thing
reef fulcrum
I mean, if you can ensure that data retains consistent, I guess so
reef fulcrum
Yea, which is one of my biggest concerns with stuff like that as it blows the memory usage out of the water potentially
reef fulcrum
yea, the entire thing is fucked and I basically just, le sigh
reef fulcrum
ngl, I keep getting more and more tempted to flip that option by default
royal hawk
I mean
We are running in doors here
The only real fix is to treat normal (fast) switches as real switches
Plus
I know about a dozen ways to DoS anything based on bungeecord- just based off of the little amount of care put in by md_5 and you can rest assured- I have no clue how I should fix any of that
Man this is so screwed
reef fulcrum
Yea, best I got is basically start rewriting a whole chunk of stuff which I really don't have the energy for or the inclination to tell people that, yea, we just broke ur shit
royal hawk
The only real option at this point; well in my book at least; is to retire Waterfall in favor of Velocity
Hard-forking bungeecord for say adventure is possible
But that’s gonna get worse and worse as time goes on
I’ll attempt to mitigate a few more things later this weekend
But I doubt the band-aid solutions are gonna hold
royal hawk
Hard-forking bungeecord for say adventure is possible
I’ve tried that. You might as well reimplement a large part of the API if you’re doing that
It was miserable if I have to say
marble kelpBOT
just👏 use👏 velocity
reef fulcrum
supporting adventure 1st party is something I wanna do, but, the entire nature of md's neglect of the API is just, urgh...
Imagine if the API actually returned things like the prefixes instead of the json content...
royal hawk
I mean at this point you could hard-fork the API and include a definition in the plugin yml of which impl to use
Paper+adventure or md’s
reef fulcrum
you can't really auto-magically pick just based on some setting
and am not doing commodore level BS in waterfall
royal hawk
or just reimplement all in the paper package
^ better option
If I have to say, that option is both cleaner and better in this case
Reimplementing the events at least

<@!371398411867521024> master plan? nope

And @Deprecate all else
If nothing else I can do that this weekend
After that next would be brigadier
forest halo
That's what we are doing with Paper, only deprecating String AND BungeeCord-Chat methods
marble kelpBOT
what's wrong with just using the adventure platform?

Fairly easy to transmit
reef fulcrum
Like, the API literally just returns json strings in some places
royal hawk
Brigadier is next up after that
Let’s get on that!!
@Deprecated use adventure link Component
forest halo
We're talking about Waterfall, phoenix
royal hawk
Yea
does waterfall also throw a warning on startup if there is deprecated stuff used like Spigot does?
reef fulcrum
No, as there is no legacy support BS
royal hawk
No, as there is no legacy support BS
Yea tho it’d be a classic md_5 move

Why /server and /send command not working?
royal hawk
Why /server and /send command not working?
Do you have the appropriate permissions and are the modules for those commands installed correctly?
royal hawk
What about permissions?
reef fulcrum
define "not working"
royal hawk
Was about to add that
rain cobalt
I type /server and /send and I get Unkown command. Type "/help" for help.
rain cobalt
/bungee works
royal hawk
Screenshot of the F3 screen when connected please
reef fulcrum
corrupted jars, apparently
royal hawk
The modules go in the modules folder not the plugins folder
reef fulcrum
Ah, yea...
delete them from the plugins folder
waterfall already manages those for you
rain cobalt
They are
royal hawk
Clearly not: Error enabling plugin cmd_server
reef fulcrum
what's in your plugins folder?
rain cobalt
The plugins folder is empty
royal hawk
rain cobalt
After updating the jar this problem started happping
royal hawk
What are the start flags and what’s the path you’re starting it from
reef fulcrum
screenshot the contents of the plguins folder
that's specifically enabling plugins, not modules, it shouldn't be picking up the module jars from there
reef fulcrum
oh, wait, they do show as plugins essentially due to how it works, ignore that
try redownloading waterfall
something is busted somewhere
royal hawk
I haven’t changed anything in my PRs that would explain it
rain cobalt
Okay I will try that
royal hawk
So yes your jar(s) appear to be corrupted
royal hawk
reef fulcrum
seeing stuff like that which needs to butcher the classpath to work properly is not re-assuring
royal hawk
We must be both blind to not see that right away
rain cobalt
Lol I download the new jar file from https://papermc.io/downloads#Waterfall it now works
royal hawk
I would assume so; did you download the last one from songoda?
royal hawk
Don’t ever download these things from unofficial sources
Moreover in this case- I’ll investigate what they added to the projects
As it is a potential security and safety hazard
rain cobalt
royal hawk
Well at least the jar is unmodified
Still though; strongly advise against using non-official sites

Does anyone know why trying to setup a network with a 1.8.8 sub-server on Ubuntu doesn't work? (It works fine on my PC, which is Windows 10, but not on any of my VPSes, which are Ubuntu -- one is Ubuntu 18.04.4 LTS and the other is Ubuntu 20.04.2 LTS)
Logs:
[04:43:17 WARN]: Event PostLoginEvent(player=xNitrate) took 291ms to process!
[04:43:17 INFO]: [xNitrate] disconnected with: Could not connect to a default or fallback server, please try again later: io.netty.channel.AbstractChannel$AnnotatedConnectException
[04:43:17 INFO]: [/LAN IP:59840|xNitrate] -> UpstreamBridge has disconnected
Basically, I set it up where the network is the latest WaterFall version with a patch to allow 21w05b clients (it also didn't work with just straight WaterFall 1.16.x). And the lobby is PaperSpigot 1.8.8.
Like I said, it works fine when I host it (both) on my PC (Windows 10) and, for some odd reason, it works when I proxy the connection from one VPS to the other (different networks completely), but when I host it on only one of my VPSes, it gives me the AnnotatedConnectionException. Which is different from the exception it gives when it plain cannot find the server (if the sub-server is offline, port-blocked, etc.)
Any help would really help me out.
Thanks!
P. S. This error happens whether you:
1. Are on the WaterFall server (connected) and you are trying to go to the 1.8.8 server.
2. Are trying to connect to the WaterFall server when it has the 1.8.8 server as a "default" or a "priority".
Or 3. Are being sent from a working Paper server to a 1.8.8 Paper server while being connected to the same WaterFall network.
All of these being when they are all (the WaterFall servers and Paper servers) being hosted on the same Ubuntu VPS.
don't use the external IP for the same host is my guess
latent lance
?
reef fulcrum
all that tells us is that the conection failed \
latent lance
Huh?
The picture is just redundant information that I'm trying to reiterate to say that the exception is different from the "pinging timed out" error.
reef fulcrum
Which is likely a routing issue if the only difference between the two servers is their host
what IP are you using in waterfall to connect to that server?
latent lance
You're not understanding my case.
They are on the same network.
I use 0.0.0.0:port
reef fulcrum
you're saying that waterfall cannot connect to a server on the same VPS?
latent lance
Yes.
reef fulcrum
Use 127.0.0.1, 0.0.0.0 is just special to mean "all interfaces"
latent lance
But, it can to one not on the same VPS.
Just so you know, I do know a lot about networking. :P I almost got my A+.
But, I'll try it.
I was just using 0.0.0.0 because that means localhost and it is on the same VPS, thus localhost.
reef fulcrum
oh, 0.0.0.0 is supposed to route to local, not something you should apparently rely on, some OSes apparently forbid it, some deal with it weirdly 🤷♂️
latent lance
Hmm. Okay. It worked on my Test VPS, but it is giving me a "readAddress(..) failed: Connection reset by peer" error on my production VPS.
And it was really weird, when I first logged on to my production VPS, I did /server <1.8 server> and it worked for like 1/2 a sec then it kicked me to the lobby. Now, I can't even get that far.
reef fulcrum
firewall?
latent lance
I don't think so.
Plus, I have it ufw allowed anyway.
This is on the server I was trying to connect to. It was being spammed.
reef fulcrum
ancient server version doesn't support modern java
latent lance
I have Java 8. Let me see if that works.
Yo. It works.
Dude. Thanks. I legit don't know how to thank you.
I've been trying to deal with this problem for about 1/2 a year now. I'm so stupid not to use the 127.0.0.1 thing... I just thought it was redundant.
But, yeah. Thanks.

There is a way to lower the use of waterfall CPU when so many packets are sent (such as when loading the world). How I understand this depends on packet compression.
On waterfall network_compression_threshold: 256
and -1 in the server paper
royal hawk
Depends. Disabling the on-server compression will only lighten the load a little
Waterfall still will itself compress and decompress incoming packets
Additionally, Waterfall is probably as efficient as Bungeecord gets. If you want anything that is ever slightly less heavy I suggest you look at Velocity
Though, as is, Waterfall uses rather little processing power and is perfectly capable of multithreading/ using multiple cpu cores efficiently
royal hawk

so I really dont recommend modifying the compression on the proxy itself

The problem is that when 200 players switch servers for good or bad, it uses about 7 cores. So the only ways to solve are: either use more bungee or use a tail system to lighten the load.
lusty hornet
we are above an i9
royal hawk
make a cpu profile with spark while youre under load and post that here
lusty hornet
a single join in a vanilla server (without plugins) uses about half a core
royal hawk
yea thats a bit too much.
kind gorge
How do I assign the permissions for /server /send etc.?
lusty hornet
yea thats a bit too much.
read pvt pls
