Hi there, Does this project create a Minecraft server accessible by Minecraft PE players?

Hello, I have a rpi4 with 4gb of ram and I noticed you updated the DOUBLE_RAM variable to just RAM to allow allocation beyond 2gb which is great, however my pi is just using the default now. I installed a different (newer) version of balenaOS, i think 1.51, as i was wanting my minecraft server on a different SD card, however when I set the Device Variable "RAM" to "4G" it's only using 1gb.

Any help would be great, it's probably something simple.

Describe the bug
There is an error when attempting to start the mc-server service. mc-server logs show:
mc-server Starting jar file with: 1G of RAM 20.07.20 16:33:34 (-0500) mc-server Error: Invalid or corrupt jarfile paper.jar 20.07.20 16:38:46 (-0500) mc-server Setting device hostname to: balenaminecraftserver 20.07.20 16:38:46 (-0500) mc-server OKStarting jar file with: 1G of RAM 20.07.20 16:38:46 (-0500) mc-server Error: Invalid or corrupt jarfile paper.jar
and continues an infinite loop.

To Reproduce
Steps to reproduce:

1. Follow the tutorial. Once on balena dashboard with Pi running all services after running balena push , the mc-server gives issues on attempting to start with paper.jar

Expected behavior
I believe the mc-server service automatically fetches the download for paper.jar from a website, however it seems to fail for mine.

Raspberry Pi (please complete the following information):

• OS: [balenaOS 2.51.1+rev1]
• Version 11.4.10

Additional context
I've attempting to download the paper.jar file directly to the mc-server folder, then using balena push <appName> but it detects it as too large of a file and ignores it from the push.

Describe the bug
I am unable to get the update file for version 1.16.4.

To Reproduce
Steps to reproduce the behavior:

1. I have ENABLE_UPDATE=true
2. In HostOS I do the following commands:
3. find . -name "*paper.jar" -exec rm -rf {} ;
4. find . -name "*1.16.3*" -exec rm -rf {} ;
5. find . -name "*copied.txt" -exec rm -rf {} ;
6. Restart mc-server
7. I see Starting minecraft server version 1.16.3 in the logs

Expected behavior
Since https://papermc.io/ci/job/Paper-1.16/lastSuccessfulBuild/artifact/ shows the correct version, I do not know why it is not using 1.16.4.

Screenshots
If applicable, add screenshots to help explain your problem.

Raspberry Pi 8GB:

Im using the ballena installation, and if I set the RAM/2GB this message appears:

12.09.20 02:31:18 (+0200) mc-server Starting jar file with: 2GB of RAM
12.09.20 02:31:18 (+0200) mc-server Invalid initial heap size: -Xms2GB
12.09.20 02:31:18 (+0200) mc-server Error: Could not create the Java Virtual Machine.
12.09.20 02:31:18 (+0200) mc-server Error: A fatal exception has occurred. Program will exit.

I am trying to create a forge server but I have a question once you uploaded all the files, how do you select the jar file so that it runs in forge and not in paper?
Is there a way to install multicraft?

Hey. I followed this tutorial:
https://www.balena.io/blog/how-to-create-a-minecraft-server-for-the-pi-4-with-balena/
https://github.com/AlexProgrammerDE/balena-minecraft-server

First off, thanks! It works, locally. There is the issue. I portforwarded ports 22 (ssh), 25565 and 25575. People can't login using my public IP, but instead of not connecting or refusing connection, it times out instead.

To Reproduce
Steps to reproduce the behavior:

1. Follow this tutorial: https://www.balena.io/blog/how-to-create-a-minecraft-server-for-the-pi-4-with-balena/
2. Deploy this package using balena (literally the button present on the page): https://github.com/AlexProgrammerDE/balena-minecraft-server
3. Edit in SSH via WinSCP the server.properties file and set the server IP to the local IP of the raspberry pi 4
4. Port forward ports 22, 25565 and 25575 all with protocal TCP/UDP. For each port, external and internal port range the same.
5. Restart the router (NETGEAR Nighthawk r7000) and restart the balena application.

Expected behavior
The server starts up. I can just connect with the local ip 192.168.1.34. Also the MOTD shows up when you add that server. I expect it to also allow me to enter SSH via public IP and enter the server via public IP.

Screenshots


The first picture shows that locally this port is open, but publically (second picture) closed.

Port forwarded ports ^^^

"Networkerror: Timed-out while connecting to: "84..."

Timed out using public IP.

Additional context
I can't find a firewall on my router. I have seen something that could be it, but I'm not sure. It's called WAN. Haven't touched it yet, but I wanted to ask first if someone else sees a solution in this. Everything regarding the tutorial was entirely done trying to avoid manual stuff. For example, the "deploy using balena button" instead of manually looking into it. Furthermore, I want to say sorry in advance, because the chances are big it isn't the problem of your tutorial or package, but because I am blind. But I've already spent hours into it, asked advice from others, but I'm just stuck. Lastly, everything regarding balena works. I can just go ahead play on it on local network. It's just the public IP that is not working.

If I missed anything, feel free to ask for it. Ill try to respond as fast as possible! Thanks in advance!

Would it be possible in any way to connect a display to a Pi and have it show the Pi statistics and mc console.
If this is possible how and what can you display on it.

when I log in to the serwer I get a user verification error despite the option turned off online mode in server.proporties.

Hello, I absolutely love this project me and my friends have had such a good time with the server! I wanted to know if you could help with creating a scheduled restart once per day for the server. I know this can be done using a crontab event but I am not too familiar with docker or balena so I cannot figure out how to make this a reality. This could also be a really cool feature that could be added as maybe an optional service within the docker if you wanted to.

Simple question: This guide on BukkitWiki explains how you can attach an IDE's debugger to the minecraft server by editing the startup command line arguments. Where do I configure those startup arguments for my balena mc-server?

I've been trying for hours to allow SCP connections to my Pi for hours and am having no luck with it. Every time I try and connect it the connection just times out. Anyone have any idea why?

Where is the option to enable my 4Gb pi to run with 2GB of ram? I had trouble finding that from the instructions in the tutorial here as well from the balena website. I have the server running and port forwarded, everything works swimmingly, just hoping to increase the loaded chunks. Thanks

Raspberry Pi Setup
Host OS Version: balenaOS 2.56.0+rev1
Supervisor Version: 11.14.0

I just tried to setup my Minecraft server, and followed the instructions as set on the GitHub page.
I did set the RAM environment variable to 2G instead of 1G.
It connects to Balena Cloud and I can see everything there, but it keeps failing on
"mc-server: You need to agree to the EULA in order to run the server. Go to eula.txt for more info."
I've gone into the eula.txt file and I confirmed that it has "eula=true" inside the file.
Attached is a screenshot of the log files.
Any ideas on how to resolve this?

I'm having an issue flashing the .zip file in Balena Etcher. when I click flash from file I get an error that says "Error opening source, can't find a matching file in the zip archive"I tried uninstalling and reinstalling Balena Etcher but to no evail.

To Reproduce
Steps to reproduce the behavior:
Click flash from file and select the zip file balena-minecraft-server-master

The world generating process start and finish, but i cant access on minecraft.

1. Restart or Turn on raspberry
2. Scroll down to on logs, after world generation
3. See error.

In logs it says "Unable to determine local host IP, please set server-ip in server.properties: balenaminecraftserver: balenaminecraftserver: No address associated with hostname".
I tried to put the id of the raspberry and the public ip of my router. It didn't work

I priviously had a paper.jar error, but i resolved it like in other threads

Hey Alex, someone shared this we me today: https://github.com/docker/dockercraft

It's completely crazy LOL. It allows you to control and visualise docker containers from inside Minecraft 🤣 You could theoretically have the containers on a balena device (including the supervisor) show up in here using io.balena.features.balena-socket to map the docker/balena engine socket.

The project looks abandoned (last commit is 3 years ago), but I wanted to share it with you in case you haven't seen it because it's too awesome not to.

Describe the bug
The minecraft server was running without problem on a Pi 4GB with mods installed (Essentials). I changed one variable there over WinSCP and then the server stopped working, showing the error Error: Invalid or corrupt jarfile paper.jar on balenaCloud. This also happened when I fisrt set it up but was able to circumvent it by using the solution from a previously resolved issue ( setting ENABLE_UPDATES to true ).

To Reproduce

1. Change variable in mod
2. Reboot Pi (log attached)

Expected behavior
I expected the minecraft server to start up normally

Additional context
After typing this out, I might have realized the problem... Maybe the minecraft server wasn't properly shut down before messing with the variables via WinSCP, could this be the problem? If so, how could I fix this and save the server data?

ENABLE_UPDATES is still set to true

I see at the that bedrock is listed under the custom server of your article. I was wondering on how to install it as I believe that bedrock is not based of Java.

Thanks for any help.
Andrew

I followed the tutorial on the Balena website (which is the same one that is written on this github page) and for some reason, it just sometimes restarts randomly. It does this a lot to the point it is very frustrating. I believe this is something to do with wifi-connect since the mc-server service gives no output. The wifi-connect service on the other hand prints out a random line and then "Skipping Wifi Connect".

Don't know if I can ask the question here but I did not find another option. First of all great product. With your setup the server was up in no time.

I build it for my daughter, I have knowledge of raspberry pi's, see of minecraft. So I want a home server where see can play with friends. But I think what I want is not possible, but want to ask it anyway.

See has minecraft version 1.16.200 (updated a couple of minutes ago it was 1.16.101) on her iPad. But I cannot get it connect to the minecraft server, local and online (after port forwarding) not possible.
I tried the default port number 25565 as port number on the iPad and also port number 19132 from outside (found some info that some versions need this port).

But sadly no luck. Am I trying something to do which is not possible at all. So my question is, which versions/devices can connect to minecraft server? I thought I read that all devices working with minecraft on the raspberry but cannot find a solution. Hope you can help me. Feeling pretty stupid right now 😌

I was looking through the documentation for the server and I couldn't seem to find anything about how to change the server from vanilla/paper to forge/modded and was wondering how that would be done?

Ive moved my forge server jar file over to my raspberry using winscp. But the log reports it was unable to access the jar file

Describe the bug
The server crashes, cant connect to rcon, server wont start, server wont update versions, etc

Sometimes when trying to start the server it will not start, sometimes it will, i could connect to the rcon once, and havent been able to after that

Expected behavior
Everything to work, the server not crash, rcon to work

Hello, this seems very appealing to me!

Currently I run Raspberry Pi OS Lite with PaperMC 1.15.2.
Can you say if there will be any performance improvements by switching to balena-minecraft-server?

I guess I will test it anyways, but it would be nice to know what I can expect.

So I have been have been constantly getting this error. I have my pi hardwired with and ethernet to my router so i don't use wifi with in and I don't plan on moving it around. Its not that big of a problem its just really annoying.

A new Raspberry Pi 4 with 8GB of RAM has dropped.

Describe the solution you'd like
I think the README should reflect the new version (and perhaps also the code, I am not sure if anything is software-locked). Just to mention it, if it's even worth it to have 8GB of RAM for a Minecraft server (why and for whom?)

Hi so it says my server has a max of only 1GB and I am running on a raspberry pi 4 with 4GBs of ram. If you could help me fix this that would be great.

Where does the server save the world data? I would like to be able to backup my worlds and know where to save them if i wanted to change worlds from config file. I assume this can be done?

Hi Alex,

Just thought I'd try and raise this here as a topic. I noticed your gif showing the chunk loading and unfortunately cannot yield the same result despite using 2GB on my RPi 4 (4GB).

Do you have any advice or tips on optimizing the pi to ensure it can get the same performance yours has? Currently my console is littered with things like:
Can't keep up! Is the server overloaded? Running 73827ms or 1476 ticks behind

I am currently struggling with very little linux knowledge and the desire to update from my previous MC server (1.15.x) to the most recent one (1.16.x) and I don't see any documentation on how to do this.

I would love a tutorial or even a script to make this process seamless from putty or balena.

I absolutely love love love this software, so far it's been the most stable and best server ever! Thank you guys so much!

Also: I am a noob, so if I'm missing something obvious, please treat me like a noob and help me learn and get better! ^_^

Hi uh I just balena push the package, everything is finish however when I tried to connect to the server using balenaminecraftserver it shows 'Can't Resolve hostname' and 'Unknown host'. I don't have any idea what went wrong there, you have any idea? Thanks in advance

Connection timed out
So we've set up a balena minecraft server on a Raspberry Pi 4 (8Gb RAM), went for the dev-OS installation, connected smoothly to both the gameserver as well as the scp-server, took the Pi to it's new location where it's meant to stay and connected to both servers again without any problems. Through out all those connections we always were in the same local network as the Pi itself.

Now when we try to connect to the scp-server from home, without being in the same LAN as the Pi, WinScp is searching for the host and gives us a Connection timed out error as shown below.

The IP-adress is blended out, since we're trying to connect over the external server IP. As soon as we WinScp-connect over the local network, sitting right next to the Pi and using the internal IP, we can connect without problem. So, what are we doing wrong?

What we've tried

• Followed WinScp's guide on the error
  ** Extended the server response timeout
  ** Introduced WinScp to the firewall
• Checked if all the ports were open on the Pi - all required Ports (in this case Port 22) are open
• Tried FileZilla - gets the error as well

I am currently running a paper and geyser server to host a bedrock server (balena on a pi 4)... But I cannot get the public URL balena feature to work with bedrock minecraft. (It does work on local IP). I have my docker-compose.yml is like this:

version: '2'
services:
  mc-server:
    network_mode: host
    restart: always
    build: ./mcserver
    privileged: true
    labels:
      io.balena.features.dbus: 1
      io.balena.features.supervisor-api: 1
    volumes:
      - serverfiles:/usr/src/serverfiles
      - servercache:/servercache
    ports:
      - "25565:25565/udp"
      - "25565:25565/tcp"
      - "25575:25575/udp"
      - "25575:25575/tcp"
      - "80:19132/udp"
      - "80:19132/tcp"
     # - "443:19132/tcp"
     # - "443:19132/ucp"
volumes:
  serverfiles:
  servercache: 

That should be making the geyser port of 19132 be on the host, 80 - the port used for public URL.

I enter in the details:

But it just does not connect - like it would normally if the server was offline... Yet I can connect to the local IP...
Any ideas/help?

DOUBLE_RAM does not work when using a 1.16.1 paper-91 jar file.

To Reproduce
Go to https://papermc.io/downloads
Download the newest version of paper
Replace the paper.jar file with the new on using SCP
Set DOUBLE_RAM to true

Expected behavior
I expected the DOUBLE_RAM variable to allow the jar file to use 2 GB of RAM. However it did not. It still starts with 1 GB of RAM. While I was using the original

Hi am having trouble updating my server from 1.16.1 to 1.16.3. Could you add this to the tutorial.

I've been encountering a problem where the whitelist.json file appears to be wiped on each full restart of the server. It's odd as things like the world and plugins folders don't appear to have the same problem.

Steps to reproduce:

• Install and start server following the instructions
• Whitelist a player
• Either restart the device remotely in balenaCloud or turn off the device physically and turn it back on
• Whitelist will be reset

I have been trying quite a few ways to install the forge instead of the spigot but I cannot solve the problems it gives me: it does not find the file, it does not download ... If you could locate a file with forge I would really appreciate it. Thank you.

Describe the Bug
When starting the Minecraft service from balena dashboard the Logs panel show:

To Reproduce
Steps to reproduce the behavior:

1. git clone [email protected]:AlexProgrammerDE/balena-minecraft-server.git
2. balena login
3. balena push Minecraft-Server
4. Open balena dashboard and check Logs

Expected behavior
The Minecraft service to start without error.

I have followed the guide and probably a 100 other pages/guides/forums trying to find what I need but haven't quite got it but I know i'm close.

I've setup the server and everything seems to work locally (SCP window, playing the game on a local pc running Java edition, etc.) but I can't seem to get the server set up for remote/non-local play. I have a No-IP account with a hostname that's configured to update when my netgear router is assigned a new IP from ISP (DDNS configuration), but there's something with my port forwarding settings that's probably wrong. I followed the No-IP guide best I could for port-forwarding netgear routers and this is my configuration screen:

I set the service to 25565 port and used that service for the ip of 192.168.024 (I think i managed to set it to static?) which is what my Pi has been connecting to and matches the Balena dashboard IP.
However, either this configuration is wrong or i'm using the wrong connection method in game.
In game under direct connect i'm doing https://myhostname.ddns.net:25565 where myhostname is being replaced by my actual hostname on No-IP dashboard.

Any help would be great!

Thanks

My Minecraft server has being working but now it disconnect the users after 30 seconds.
I have set the server to 2GB of RAM on a pi4.

Anyone with the same problem?

The upgrade code will have a problem if paper.java file for a newer version of the minecraft server is smaller than the previous version.

Currently, the the "-c" parameter is passed to the wget command. This will only download new bytes if the new file is a lager size than the previous version. Also this will only download the delta in bytes, which may not be right, if changes to the jar happened anywhere besides the tail of the file.

I noticed this when trying to upgrade from 1.16.1 to 1.16.3, as the

1.16.1 jar is 46982714 bytes, while the 1.16.3 jar is 46848610 bytes.

Hello,

I followed the tutorial and set up a balena server and everything worked perfectly. I want to make the server into a Tekkit server (Minecraft version 1.2.5) but I can't get that to work. I've remotely accessed via winSCP into the server and tried replacing the serverfiles folder with a Tekkit folder with the .jar file and everything, but balena won't run the server. I'm wondering what do I need to change within the dockerfiles and start.sh files to get this to work? Is it even possible? Do I need to make a new service from within the dockerfile to run this? Any help would be much appreciated.

Hello i am trying to create a forge but don't know how to change the files to forge
Could u help me

I tried looking around on the internet but couldn't really find anything, so I hope it's ok if I ask here.

I was wondering how you would recommend updating the balena minecraft server to 1.16 and resetting the nether once the spigot and paper versions are released.
Here's what I was thinking:

1. stop the minecraft server
2. connect to the Pi4 using SCP
3. backup the world files
4. update to 1.16
5. delete level.dat file from nether folder
6. restart the server

I would greatly appreciate any help I can get with step 4 or any corrections you would have for the rest of the process. Thanks in advance!

How to delete bungeecord?

i have everything set up and operational, but im not sure how to modify the ranks. putting commands directly into the mcserver terminal on balena brings up filepath errors and the ops.json file is blank so i dont even know how to really start.

Starting jar file with 2GB of RAM.
Error: Invalid or corrupt jarfile paper.jar.
ENABLE_UPDATE to true didnt helped

Hi,

I wanted to use a Balena image instead of ubuntu for scp container :

Instead of :

• FROM ubuntu:16.04
  I use :
• FROM balenalib/%%BALENA_MACHINE_NAME%%:latest

Then my attempts were always rejected and I think found the root cause. I had to change :

sed -i 's/PermitRootLogin prohibit-password/PermitRootLogin yes/' /etc/ssh/sshd_config

To this

sed -i 's/#PermitRootLogin prohibit-password/PermitRootLogin yes/g' /etc/ssh/sshd_config

It works like a charm now. Do you want a PR?
