Is there a way to spawn a baby zombie without it riding a chicken?
torn robin
zombie.setBaby(true)
open girder
could I make it so in the constructor of each enchantment I add Main.getInstance().getPluginManager().registerEvents(this, Main.getInstance())
paper compass
without it riding a chicken?
tiny dagger
zombie.leaveMount();
torn robin
world#spawnEntity ?
sturdy oar
save them in an enum
torn robin
@open girder if you're using the static singleton you don't need to even have the JavaPlugin argument
paper compass
z.leaveVehicle()?
open girder
static singleton?
sturdy oar
for (Listener listener : ListenerEnum.values())
Bukkit.getPluginManager.registerEvents(this, listener);
@open girder
torn robin
Main.getInstance is the static singleton
open girder
ah thanks
torn robin
@sturdy oar how would that work exactly
sturdy oar
you have an enum with instances of listeners
and you simply get them all with enum.values
torn robin
wouldn't the be an enum class?
open girder
in my case i think that would translate to
for(Listener listener : EcoEnchants.getAll())
Bukkit.getPluginManager.registerEvents(this, listener)
i don't have an enum class but I don't need one here
sturdy oar
now ignore the fact that it's red
but you would have all of them like this
since from your snippet it seemed like you didn't have any constructor argument
you could do it
torn robin
so you'd have to do
for (ListenerEnum listener : ListenerEnum.values())
Bukkit.getPluginManager.registerEvents(this, listener.getValue());
for (Listener listener : ListenerEnum.values())
Bukkit.getPluginManager.registerEvents(this, listener);
I don't get how this works
oh ok
just making sure
torn robin
should work
sturdy oar
what's that casting 😐
torn robin
assuming EcoEnchants has all of them
open girder
i can cast enchantment to listner because they all implement listener
sturdy oar
ye
torn robin
unless Enchantment is the vanilla implementation
sturdy oar
just loop through Listener
open girder
it is the vanilla implementation
torn robin

strange grove
does anyone know how to access an array list that holds a string and get that specific string for the specific entity that has that string?
tiny dagger
contains(string)
tiny dagger
remove(string) returns a boolean if it was found as well
tawdry venture
alright why does my IDE says 'can only iterate over an array or an instance of java.lang.Iterable' for the player.getInventory().iterator()????
tiny dagger
well
strange grove
so returns true or false?
tiny dagger
it doesn't implement iterable then
strange grove
*it
tawdry venture
that method literally returns a ListIterator
tiny dagger
maybe
strange grove
anyway here is the reast of my ocde
tiny dagger
but it's not a iterable class
tawdry venture
that extends Iterator
tiny dagger
it needs to have iterator();

Iterator isn’t Iterable

public void ImgCommand(final CommandSender sender) {
if (sender instanceof Player) {
Player player = (Player) sender;
World world = Bukkit.getServer().getWorld("world");
Location l = player.getLocation();
Collection<Entity> nearbyEntities = l.getWorld().getNearbyEntities(l, 8, 8, 8);
if (player.getNearbyEntities(5,5,5).contains(imgname)){
player.sendMessage(ChatColor.BLUE + "This is " + imgname + ".");
}
}
}```I think
I see now why
undone narwhal
getNearbyEntities is not a String list
undone narwhal
What is your goal?
strange grove
to get the image name of an itemframe
and detect where it is
by timing it and spawning and armor stand
tawdry venture
thanks I figured out
strange grove
then deleting the armor stand after it is finished
undone narwhal
then you have to check for each entity in the getNearbyEntities if the type is instance of ItemFrame, and then display the entity.getCustomName() ?
strange grove
that's it?
are you sure that could get the function that holds the names?
cause I also did this
imgname.add(name);
to add the string name
imgname.add(name);```of the image to the array list
but I want to call it
undone narwhal
the #contains method to getNearbyEntities isn't string, it's Entity collection
strange grove
yeah
probably should delete that
well the one that's being defined before the other one
undone narwhal
I'm lost lmao
strange grove
if (sender instanceof Player) {
Player player = (Player) sender;
World world = Bukkit.getServer().getWorld("world");
Location l = player.getLocation();
if (player.getNearbyEntities(5,5,5).contains(imgname)){
player.sendMessage(ChatColor.BLUE + "This is " + imgname + ".");
}
}
}```so something like this correct?
cause i'm asking
if it contains the imgname
undone narwhal
What's imgname type?
strange grove
it's basically
getting the args
of a command
that is placed
and naming an image after that
/af <nameOfimg> <UrlOfImg>
like this
undone narwhal
getNearbyEntities is a Entity collection, you can't use a contains(String) method
Cause Entity is not a String
strange grove
then what do i do?
strange grove
heres my code
@Command(name = "ImgName",
aliases = {
"In",
"ImageName",
"ImageNameDetector"
},
usage = "/ImgName",
fallbackPrefix = "animatedframes")
public void ImgCommand(final CommandSender sender) {

for(Player player : Bukkit.getServer().getOnlinePlayers()) {
for(Entity entity : player.getNearbyEntities(5, 5, 5)) {
World world = Bukkit.getServer().getWorld("world");
Location l = player.getLocation();
if(entity instanceof ItemFrame) {
ItemFrame itemFrame = (ItemFrame) entity;
if (itemFrame == imgname){
player.chat(ChatColor.BLUE + "This is " + imgname + ".");
}
}
}
}
}
}
@anyone
should this be able to work?
little salmon
yes
undone narwhal
no
strange grove
it's for getting the imgname of na entity
sturdy oar
what is that library with @Command annotation
undone narwhal
ItemFrame instance cannot be equals to a String
torn robin
swap the fors
undone narwhal
ItemFrame == String
torn robin
you should tell each player per item
strange grove
it does not
torn robin
not go through each world per player
strange grove
itemFrame.contains(imgname);
No
undone narwhal
That's okay..
strange grove
if (itemFrame.getCustomName(imgname)){
player.chat(ChatColor.BLUE + "This is " + imgname + ".");
}```something like this?
or am I wrong yet again
and money is not always the answer
undone narwhal
itemFrame.getCustomName().equals(imgname)
strange grove
oh
undone narwhal
or equalIgnoreCase

I am trying to teleport a horse to a location, it works fine unless there is a passenger on the horse in which case nothing happens.

yeah teleporting animals while something is mounted on them
is buggy
I think you can just get around it with dismounting the player, teleporting the player, teleporting the animal on player new location , then making the player mount the animal again

i just use

pm.registerEvents(this, this);
PluginManager pm = Bukkit.getPluginManager();
pm.registerEvents(this, this);
i believe using playerjoin might limit the amount of events being registered
so if you make the thing send a log on the event
take damage
you wont recieve anything
try putting a info thingy into the event

@errant python What to choose
errant python
In the code you posted I cannot see you moving those crodinates.
hollow thorn
i did loc2.add(loc2)
loc2.add(loc2); this changes the coordinates
and if it was inside the entity
then where are the particles
errant python
@hollow thorn Location.add(double x, double y, double z), ok, are you right next to world center?
@ripe ledge Any of those work.
digital pebble
in cube runner plugin when i do /cr setzone cuberunner command it tell me a error that (an internal error occurred while attempting to performing this command)
hollow thorn
@hollow thorn Location.add(double x, double y, double z), ok, are you right next to world center?
@errant python i use a projectile launching plugin that uses the same method at the same coordinates so i dont think so
errant python
@digital pebble Id contact the plugin developer.
@hollow thorn Oh, if your using an API to launch it, then I really don't know man. I thought you had created all the methods :/
hollow thorn
i created the method
im not using an api
i used the same code to move a coordinate
errant python
"i use a projectile launching plugin"
errant python
Ok, sorry I didn't understand.
@hollow thorn To be honest, I think you try and get the spawn working with hard coordinates, once your sure everything else is working, then move to dynamic coordinates, if you have not already.
hollow thorn
i have got aplugin to work with spawning chickens
errant python
i have got aplugin to work with spawning chickens
@hollow thorn Cool! Then try and replicate the results with hard coordinates. Sometimes you forget about dependancies when ^C ^V'ing your own code.

thats only way that message prints

Well.. talking about async
I've been modifying my code and I've noticed a thing
i was printing out some messages for debugging, and the sender is "pool-10-thread-2" does that mean the messages are being sent from a thread which is not the spigot main thread?
That also seems to be the cause of my issue because the command are not being dispatched

Dont touch mcprohosting it is a scam
even though i know their support is amazing
They pay a big youtuber to get popular and then offer horrific hosting
i'd host on a vps too
if i knew a good site for one

There is or Serverpro (The support there is AMAZING, they always answer on mail in like 30 min)
And there is ShockByte (Support less better, but I thing they are more cheeper)

i'll check it out

frigid ember
i tried switching to them then i found out about the size limit
ripe ledge
What the problem with the size limit?
ripe ledge
For server?
Storage or RAM?
frigid ember
the ram for the 15 dollar plan was 4gb vs shockbytes 6
so i couldnt run ftb on it
storage
on their budget plans
ripe ledge
This is the plans on server pro:
hollow thorn
you could just use your own pc
ripe ledge
frigid ember
the premium plans dont have a limit but they have like no ram
yeah but i dont want to leave it on all the time
Server pro is bad
ripe ledge
Why
frigid ember
Why? They offer free hosting, they're going to be bad
ripe ledge
wait what
@frigid ember I am using a MEDIUM server on server pro And I have 20 GB Storage, not 4
frigid ember
Plus the actual valid points i cannot tell since im on mobile
i meant ram on beastnode was 4
5 was the storage limit
how much is that?

are you familiar with ftb?
ripe ledge
I know it's a mod pack, right?
frigid ember
it's a total revamp really
ripe ledge
a very famous mod pack

How much players you want to be in your server?
frigid ember
not many. 6gb is the range im looking for
ripe ledge
on average
frigid ember
15
ripe ledge
15 players that gonna play a lot and load a lot of chunks?
or players that gonna be at the same place
Because more chunks the server load, the more the server is heavy (Storage)
I thing you need like 6-10 GB RAM
@frigid ember
for your server
ripe ledge
But now it's 20 GB Storage
on server pro
I thing It will be enough else you gonna create more worlds then the Overworld, Nether, and TheEnd

obtuse rose
my personal experience with OVH is random network dropping for some user (Some can join, some can't )
no personal experience for Contabo
keen compass
sounds like you didn't use their montreal DC
there was a while back a couple of years where they were upgrading their hardware for network stuff
lasted about 2-3 months but nothing too serious as far as outages went
frigid ember
contabo is good if you're okay with some CPU steal and don't worry about ddos
keen compass
cpu steal?
frigid ember
yup
keen compass
Was hoping you would elaborate in what you mean by that
frigid ember
type top in linux
see "St" stat
its cpu steal
percentage
if it's higher than 0, your provider is taking some of your CPU for other clients
keen compass
you mean their RTM software is buggy?
keen compass
Remote toolkit management
keen compass
Highly doubt they are stealing cpu cycles without using some VPS because unless you have a beowulf cluster it isn't going to be very effective
keen compass
then its not stealing CPU
every VPS has to share CPU cycles
unless you have physical processors for each VPS
keen compass
probably a monitor for stats collection for the webpanel
frigid ember
even md_5 talks bout CPU steal
keen compass
such as network, cpu cycles etc
keen compass
yes, how else do you intend to control your VPS
even dedicated boxes have web panels
otherwise how can I hard reboot a dedicated server?
keen compass
But webpanels use IPMI
wanton sigil
When developing a command in a Spigot plugin, how do you make it comply with a permission system?
frigid ember
I'm pretty sure it is CPU steal, even influxdb has a statistic for measuring CPU steal
keen compass
Unless you are guaranteed a physical processor to yourself, there is no way to prevent sharing cpu cycles between VM's
physical processor isn't the same as cores either
frigid ember
you should google about it or something, you're talking without knowledge
keen compass
I am talking from personal experience because I setup servers all the time
keen compass
Then you should know that sharing cpu cycles is something you can't prevent unless you have a dedicated processor
@frigid ember just create a report stating you want it deleted
frigid ember
ok
I don't know how it's done, but they do it, I contacted contabo support to reduce CPU steal and they did it, performance got better
keen compass
they probably just gave your VM a higher priority
which just means you get more time with the cpu cycles
keen compass
Well the only other thing I can think of is they were just limiting the amount of processing power alloted
You can term it cpu stealing, but I can tell you that isn't an accurate way to state what was being done
frigid ember
that's how everyone seems to be calling it, Linux itself having a stat called st, which stands for steal contributes to it
keen compass
st is a simple terminal implementation for X
since I don't use such a terminal odds are it was just buggy or just had too much resources dedicated to it
keen compass
what you run for ssh has nothing to do with the terminals available on the server
I should say what you choose to run for a client
There is multiple terminals usually in linux depending on the distro you decide to use
dusty topaz
Can someone code review this small tasks thing I made? I know it can be improved greatly I'm just not sure how

wanton sigil
is this the best way for implementing a permission system in a command? ```java
if (!sender.hasPermission("plugin.commandname")) {

}
but I intend to make something using the riot api, so I picked a random league of legends item lol
keen compass
should return true if you want to send your own message @wanton sigil
otherwise it will send 2 messages
dusty topaz
try {
return scheduledFuture.get();
} catch (InterruptedException | ExecutionException err) {
err.printStackTrace();
return false;
}
Oh gotcha
dusty topaz
I wanted something here to have it timeout
balmy sorrel
Hi guys, I'm developing a plugin but I have errors :/, like the commands I have before worked and now they don't, it doesn't tell me any error in eclipse or anything
dusty topaz
But having it timing out threw loaaadds of timeout exceptions
dusty topaz
yeah, i was catching and printing
I set the timeout as a flat constant + the delay passed in
but it would still timeout every time
keen compass
well not sure why you would want it to timeout
dusty topaz
incase it gets stuck pinging the API or something
keen compass
unless you are tying to remove stuck tasks
in which case you need to just kill it then XD
harder to do if you just have the main thread though
easier to implement with multiple threads
but you have two ways to do it. Either a soft terminate or hard terminate. Soft terminate you just implement a variable that the task checks to see if it should continue to run
a hard terminate is where you use other methods to kill it
dusty topaz
i'm currently doing a soft terminate right?
keen compass
I think so, hard terminating is not always easy to implement and doesn't always work depending how the task is stuck

yeah
i just don't want the program to freeze up
since it's a fixed threadpool size

Hi guys, I'm developing a plugin but I have errors: /, like the commands I have before worked and now they don't, it doesn't tell me any error in eclipse or anything. I hope they help me because I'm pretty frustrated
dusty topaz
if they all get stuck then the program breaks (i think, at least that's how it works)
keen compass
@balmy sorrel not really giving much to help you with
in that case you could just resort to reloading your plugin @dusty topaz which is equivalent to just nulling everything
balmy sorrel
It tells me this when entering eclipse
keen compass
ewww node.js
highly don't recommend using such things in plugins, but whatever up to you. But it is telling you that it can't find node.js
balmy sorrel
What do I do, sorry, I'm new to this plugin
dusty topaz
you install nodejs
and add it to your path
or consider using IntelliJ and not messing with node
balmy sorrel
Where do I install it and how do I put it?
dusty topaz
i think google can help you with that
keen compass
I don't recall eclipse needing node.js though o.O
balmy sorrel
Yes xD
rancid crow
what events do i need to check to detect if the item in the main hand of a player is switched or removed?
keen compass
if you are not able to fix it, you could try using a different IDE @balmy sorrel there is IntelliJ and Netbeans. Both are decent alternatives to eclipse.

hey does anybody know of any texture packs which retexture horses as dragons? I found an interesting one but its for 1.10 and I need 1.15 compatibility.
or alternatively how to get 3d models in as textures for items?
keen compass
@frigid ember I researched what you were talking about. The ST value in top, you were mis-understanding its meaning.
keen compass
I was accurate in what I was telling you, essentially all ST means is that there is another process using the cpu cycles. It isn't really stealing, but just means something else is occupying more of the cpu cycles
so it could just been a VPS using more cpu cycles then it should have
frigid ember
someone else occupying your cycles
without your explicit permission
that's called borrowing I guess
keen compass
its not your cycles
frigid ember
well I'm renting em
keen compass
all the VPS's have to share cycles, not sure what you don't understand with that o.O
unkempt heron
Have a question, may I ask on the Discord if someone wants me to present their plugin? I'm doing YouTube
keen compass
even multiple cores share cycles with each other as well
that is why I keep stating unless you have an explicit dedicated processor
you have no choice but to share the cycles
frigid ember
I know that
but some providers share less
some more
and contabo has low prices due to how much they share
keen compass
well sure, there is a variety of implementations out there to control how much cpu time each process gets
but they are all not perfect. Some better then others. Some free others cost money lol
mainly has to do with the Hypervisor being used to provide the VM's
frigid ember
on ovh it's 0 - 0.1 CPU steal usually, whereas on contabo it's usually 1 - 10
keen compass
Well ovh uses an OS hypervisor like ESXi
I would imagine contabo took a different approach is probably using something like VMWare or KVM instead
frigid ember
yup they use KVM
keen compass
which are both not OS Hypervisors, but software hypervisors

anyone have a good way to detect minechat and similar clients?
frigid ember
why you need to detect them?
but pretty much tp them in sky if they don't fall for few mins, detected
keen compass
a good way for detecting minechat is checking if the player is moving 😛
make them move before they can chat when they join the server
unkempt heron
Have a question, may I ask on the Discord if someone wants me to present their plugin? I'm doing YouTube
@unkempt heron ??
sturdy oar
no
sleek ivy
we do ranks based on playtime and while we have an afk kick already, I hope to specifically detect chat users
keen compass
I have a couple I maintain if you want present them, but it might take you some time since they are API's 😛
keen compass
@sleek ivy do you only have 1 server or multiple?
sleek ivy
the afk kick is for any user, but before I decide how to handle them I need to be sure I can detect them
frigid ember
I use chat clients a lot to be in multiple servers at once and have automated stuff like private msg notifications, so I find it really useful and not using it for unnice stuff
sleek ivy
1 server right now, but that may change
keen compass
well if you end up with a hub server, disable play time on the hub, and make it required to move before able to join a server
and then just implement a network wide chat 😉
solves everyone's problem in that manner
their playtime doesn't increase, they get to still chat like they want to
keen compass
I am sure there is plenty
frigid ember
sadly I allowed afk time counting for too long in my server, would be unfair to disable it now after people have 100s of hours xd
sleek ivy
I'm not pleased with the one we have so I'm open to recommendations
keen compass
But, I am always a fan of allowing players to do something instead of punishing them because it doesn't align with what you are wanting lol
frigid ember
i just use redis to send msgs to bungee then bungee send it at proxy level to all players
sleek ivy
I'm not saying I'd punish them, just need to detect it so I can adapt correctly
keen compass
Well, you know what I meant lol
it isn't punishing, but your players think it is if you remove the ability to chat XD
sleek ivy
just making sure I'm clear, not you
ya
chat but no playtime, easy to do because the playtime system is custom
keen compass
really the only effective way to detect such things is if they are moving or not
frigid ember
some clients can move btw
keen compass
another way you could probably do it, but probably would cause their client to crash is to open an inventory XD
keen compass
if you open an inventory for the player, you could detect if they closed it or not within a certain amount of time
if it isn't closed odds are its a chat client
can't walk either if inventory is open
frigid ember
that's a good idea, chat clients ignore inventories and keep chatting while inventory open
gleaming helm
The client can send movement and chat packets while inventories are open
keen compass
movement packets are generally ignored if an inventory is opened. the exception is teleporting
gleaming helm
If you have an anticheat you can block them from moving with the inventory open
Nope
Incorrect
gleaming helm
^
keen compass
Well, then the server should not allow movement. Guess could make a pr for it lol
gleaming helm
😐
frigid ember
ping
keen compass
it didn't always used to be that way
gleaming helm
A number of anticheats patch it already
Yeah it always was that way
That's why anticheats have been patching it since like version 1.3
sturdy oar
Kevin_ do you want to hear another fun cheat that many don't know?
gleaming helm
I promise I know it
gleaming helm
Yeah I know I'm an anticheat dev
If you do that and move my anticheat will ban you instantly
frigid ember
what bout ping @gleaming helm
sturdy oar
the sad thing is that those things should be implemented by the server, not by developers
gleaming helm
@frigid ember Regardless of ping, packet order is the same. If you open inventory, then move without closing it, then obviously cheating.
frigid ember
ooh
sturdy oar
what's wrong with mules lol
frigid ember
good thinking
gleaming helm
It's not public. It does have some checks that can handle stuff like what you're talking about but it doesn't do dupe detection
It was primarily designed for detecting ghost clients on PVP servers.
sleek ivy
is there no type of "user agent" info that clients send to the server on connect?
gleaming helm
Which it does insanely well
sturdy oar
user agent?
gleaming helm
As in, detects more autoclickers than AGC
sturdy oar
you mean forge, vanilla etc.?
frigid ember
mc wasn't designed for it
keen compass
@sturdy oar Mules are attached to specific players. So what you do is fill the mule with items you want to dupe. Have another person open its inventory, original player owning it logs off. Now you can take the items out and close the inventory. Original player logs back in and didn't lose the items.
frigid ember
but forge sends a packet under some conditions
sleek ivy
detecting movement and inventory stuff seems hacky, I can, but I wish clients would just identify themselves
sturdy oar
doesn't Paper patch that?
keen compass
Not that I am aware of
gleaming helm
Paper patches some of it I think, but I'm not really sure
sturdy oar
ban mules i guess
gleaming helm
Yeah that's what I did
keen compass
but it isn't only mules you can do it with
frigid ember
that sounds like worst design ever
gleaming helm
Actually on my server I have some checking going on for anti-dupe
frigid ember
the .mule system
keen compass
it is actually easy to handle that scenario though
just not sure why the server doesn't lol
gleaming helm
So like if you dupe an item it'll actually detect that duplicate items exist. It has a unique key that only exists once. If the key appears twice it deletes the items
keen compass
guess I will add that to my list of PR's for 1.16
gleaming helm
It's of course not that simple and the keys are actually stored in a distributed system and it's made to be incredibly efficient, but that's the concept.
tiny dagger
do you have any public plugins? 😮 @gleaming helm
keen compass
the way to handle the mule scenario is to not allow the mule to despawn if the inventory is opened or close all inventories in regards to the mule if it does despawn.
gleaming helm
I only do custom dev work for high profile servers
tiny dagger
nothing recent? 😦
gleaming helm
Anything else I find isn't worth my time
tiny dagger
wait how do you find these servers
gleaming helm
I just ban mules and other storage bearing entities. Too much risk and my players aren't going to need them.
I have a lot of connections in that space
keen compass
so I have 3 things to do for 1.16 it seems. 2 minor pr's and 1 large pr. The large PR is going to be allowing bungee and mc server to communicate via unix sockets 😄
gleaming helm
I get recommended a lot to server owners from other people I've worked with and such
tiny dagger
imma need to start as well
gleaming helm
Unix sockets would be cool but like unfortunately...... I mean.... multi machine distributed system......
TCP is more efficient in that sense......
But yeah I'd use it if I didn't have multiple machines
keen compass
Well that is really the only ideal time to use unix sockets lol
frigid ember
I used to use file watchers for communication in same machine
keen compass
but I mean, you can do other things with it as well though if unix sockets are allowed
gleaming helm
I'm using unix sockets already for some aspects of communication
keen compass
for instance, you can transport the communication using NFS which would allow all servers to not be bound to the tcp stack directly IE, don't actually have to have the server listening on an ip.
gleaming helm
My pubsub system runs an instance on every machine in the network, so I'm using unix sockets to talk to that
@keen compass I've already got my entire network in a VPN setup so
keen compass
ah so you already have something similar then
gleaming helm
Plus the way I'm doing load balancing
It just wouldn't make sense to use unix sockets
keen compass
well, my pr isn't exactly to replace what people already have. But rather give more options that are easier to implement 😛
gleaming helm
mmm I disagree with the statement that unix sockets are easier
keen compass
Also, most people tend to mess up iptable stuff when they are running multiple servers on the same system with bungee
using unix sockets solves that
gleaming helm
For a beginner? no way
It's just a really foreign concept for a beginner to understand
But you're right about the iptables thing
Actually as a bit of a research project I wrote a scanner that scans all 16k servers in one of the server lists
Ran it overnight
Woke up to find a ton of servers with MASSIVE holes, some pretty high profile
(they were all individually emailed, dw)
sturdy oar
do you mean nmap?
keen compass
probably 75% have nothing blocked, 20% have some blocked but still big holes, and the rest are good.
gleaming helm
like custom built scanner thing
frigid ember
security is really weak in servers usually due to the nontech people running them
sturdy oar
well nmap is really amazing tho, it can basically do everything
gleaming helm
Yeah it's quite disappointing
@sturdy oar No, it can't check for weak database passwords
keen compass
I would even bet that the same amount that block nothing also respond to everything as well as don't use SSH keys at all
gleaming helm
I didn't probe for ssh auth
frigid ember
it requires kinda much work to setup good security, I still throw 5 hours at it from time to time when I think of possible vulnerability
gleaming helm
So idk the number on that but
I can tell you that a lot of them don't firewall anything
keen compass
yeah, it isn't just minecraft server's that suffer from that
sturdy oar
imagine if everyone removed root access and installed fail2ban
keen compass
in general there is many servers that block nothing
gleaming helm
fail2ban does fuck all if you have ssh keys
frigid ember
root access isn't exactly bad if the password is insanely complex
sturdy oar
just use SSH key access
keen compass
shouldn't allow root login
frigid ember
why password with is bad
sturdy oar
b r u t e f o r c e
gleaming helm
You shouldn't allow root login either
frigid ember
I use it for everything
keen compass
just because you can't log in as root, doesn't mean you can't use root btw
frigid ember
it can't be bruteforced if long
gleaming helm
Because a password has WAY less entropy than a 4096 bit SSH key
keen compass
you can always do su root if you really must use the root account
gleaming helm
You can't even THINK about brute forcing an SSH key
If an attacker sees ssh key, they give up immediately
frigid ember
you can't really bruteforce 16+ char passwords with current technology
gleaming helm
You can
keen compass
you can if the characters repeat
gleaming helm
I can guarantee you
Your password can be broken
The human mind is terrible at generating entropy
frigid ember
good luck on it then, I'm pretty confident
gleaming helm
And it's even worse at remembering entropy
frigid ember
I'm talking bout random ones
gleaming helm
If you can remember your password, a computer can break it
That's a good rule of thumb
And if you can't remember it, a computer still might be able to break it.
keen compass
with 2Ghz of processing power you can generate and test 2-3 million passwords every 5-10 minutes
gleaming helm
You're forgetting about gpu acceleration ^
Now that's really only useful if you recover a hash but
keen compass
well I am just giving like kind of the low end side
gleaming helm
Look. Just bottom line is
frigid ember
I use 36 char passwords for my vps users
gleaming helm
Don't use password auth
keen compass
that even with not much processing power you can still generate and test a lot of passwords in a short amount of time
gleaming helm
If you can control it, disable password authentication and use keys only.
I have a new node setup guide that I wrote for my current network. Step fucking 3 is to disable password auth
rancid crow
How can I detect if a player dropped an item from the main hand? I tried using PlayerDropItemEvent, but the inventory that the player has is updated already so I can't loop through it.
keen compass
if you have any repeating characters in that 36 character password, it doesn't increase its overall strength
frigid ember
why not
frigid ember
more tries
gleaming helm
If the repeating character is an entropy-adding randomly selected character then it's fine
If the repeat has any kind of non-random logic to it whatsoever it adds almost no entropy
frigid ember
all my passwords are random
keen compass
it is hard to explain why it doesn't add more strenght. Sure it increases the length of the password, but it doesn't increase its complexity
gleaming helm
Then you're probably fine, but here's the thing. SSH keys are also randomly generated and contain WAY more entropy than any password. You likely aren't memorizing your passwords anyways, you don't have to memorize an SSH key either. You just put it on your hard drive in a specific folder, and log in. And your SSH client literally authenticates you without typing in a single thing.
Also @keen compass if a randomly generated password has a repeat, the repeat is entropy-bearing
gleaming helm
This isn't crypto, this is probability and statistics but ok
frigid ember
I'm just not into using keys due to not having the experience with them and prefer having long random password entries instead
keen compass
passwords are part of crypto. Even if the password itself doesn't encrypt anything
gleaming helm
You'll thank me later
frigid ember
I mean if someone cracks a long random password, they're far more dangerous to the world than you
gleaming helm
@keen compass Crypto generally refers to how data is encrypted, decrypted, signed, verified, and all of the algorithms and theory associated.
keen compass
Most of crypto involves that yes
but you still learn about the inherent weaknesses involving passwords though
as well as strengths if you must use them
gleaming helm
@frigid ember The thing about passwords is you have to type or paste them every time you want to log in. Your experience will be way better with keys. You just issue the ssh command, select a user, address, port, and you don't even have to type or paste a password, you just log in.
frigid ember
hey guys. needed a little help. I'm trying to switch from Essentials balance to Economy++ 1.8.0 for it's job and salary features but it doesn't replace essentials. It just shows a different balance with it. How do I switch over?
gleaming helm
@keen compass Most of crypto you learn in college is about the algorithms and the mathematics, not about the human side.
Although
Nobody's arguing that
The human side isn't important
frigid ember
I don't paste my passwords, they're auto typed
gleaming helm
So ok I don't see the hangup to use keys then
You'll have the exact same experience with security that is n times better, where n is a number larger than the amount of stars in the observable universe.
literally.
frigid ember
well that only matters if you're trying to protect yourself from alien technology
frigid ember
I am
gleaming helm
The entire security world shuns password ssh auth. And it's for a reason.
The reasons which I have provided.
If you don't want to listen, don't complain if something happens.
frigid ember
I've done a lot of research about this which tells me that 16 char passwords are currently safe, only in future you'll need 32 char instead
keen compass
@frigid ember once you experience how quick passwords can be generated and tested you will probably want to avoid using them lol
gleaming helm
I've done a lot of research that says 2048 bit ssh keys are going to likely be secure for the next 100 years or until shor's algorithm is functional enough to crack a key of that size. And 4096 bit keys are still an option for the extra paranoid who are okay with waiting an extra quarter of a second for identity verification.
Nothing beats raw crypto
keen compass
for instance, a very very fast way to test passwords against ssh, is to use multiple processes and connections. For every connection it exponentially increases the speed in testing the passwords.
gleaming helm
No, it linearly or logarithmically increases the speed
The server can only handle so many requests per second
@keen compass
frigid ember
yup but how will you test a 16 char, even if it's done offline, billions per second won't be enough
gleaming helm
I agree with the point you're trying to make but that's false information
keen compass
@frigid ember 16 character password only has at most a few billion combinations
gleaming helm
Wrong again
frigid ember
wrong
gleaming helm
assuming a key set of 64 chars (which is less than actual), we get 64^16 possible combos
keen compass
well it depends on the amount of characters you have to choose from
gleaming helm
Which, by the way, is WAY FUCKING LESS than 2^2048 combinations
@keen compass Your estimate is only true if you're choosing from 16 characters
frigid ember
google says 10,000,000,000,000,000.
gleaming helm
@frigid ember That's a very low number cryptographically speaking
frigid ember
yup
gleaming helm
Go look up what 2^2048 is
frigid ember
but it's uncrackable currently
keen compass
79 octillion with Kevin's math
gleaming helm
It's not my math, it's the math of crytographic geniuses
keen compass
Didn't bother to verify the amount of characters so I assume it is accurate
Well I meant the numbers you provided
frigid ember
i see no point in going for 2^8192 combos, it's just paranoid
gleaming helm
Also no hardware supports a key size that large yet
Max you can get consumer grade is 2^4096
keen compass
2^2048 has no name for the amount of numbers it has XD
gleaming helm
4096 bit cryptography for RSA
frigid ember
I think 256 is the limit one should go for
keen compass
2^2048 has 617 decimal digits
gleaming helm
So we're acctually talking about a different type of crypto here
This isn't so straight forward
With that 2^2048 number, the only valid ones are the ones who are the product of 2 prime numbers
tiny dagger
how long did it took you to learn all these stuff
keen compass
Well, I was just calculating how large of a number it is. Which is 617 digits long XD
gleaming helm
When we talk about 256 bit crypto we're talking about symmetric key. In AES's case, that is, any possible number works
frigid ember
yup I'm talking bout AES specifically
strange grove
hey i'm having an error with my code
keen compass
I personally use elliptic curve keys
but RSA is still good too
384 bit elliptic curve keys are equivalent to 4096 bit RSA keys
