This is my first time making a bash script into a service and I'm running into an error where the service fails because it can't open a text file that is used for java arguments (user_jvm_args.txt). I assume there's some sort of permissions issue going on, but I'm at a loss. Anything helps as I'm trying to get better and learn. Thanks! Here's the service file:

[Service]
ExecStart=/home/ethan/ATM9-Server/run.sh

Here's the run.sh bash script:

#!/usr/bin/env sh

java @user_jvm_args.txt @libraries/net/minecraftforge/forge/1.20.1-47.1.3/unix_args.txt "$@"

Here's the user_jvm_args.txt file that is in the same folder as the run.sh script:

# Xmx and Xms set the maximum and minimum RAM usage, respectively.
# They can take any number, followed by an M or a G.
# M means Megabyte, G means Gigabyte.
# For example, to set the maximum to 3GB: -Xmx3G
# To set the minimum to 2.5GB: -Xms2500M
# A good default for a modded server is 4GB.

-Xms1G
-Xmx10G

Most of those are defaults, and the only ones I changed were -Xms and -Xmx. Here's the that error occurs as it shows in the logs:

I've got some high sensitivity mice that I need to lower the sensitivity on. The general solution to this seems to be to set the Coordinate Transformation Matrix to something acceptable. So I use the following values: xinput --set-prop 19 'Coordinate Transformation Matrix' 0.25 0 0 0 0.25 0 0 0 1 This works fine, except, that I finally realized it was causing me issues while playing minecraft. What happens, is that when I hit any key that gives me back my cursor, as soon as I move my mouse, the cursor jumps to the top left quadrant of my screen. The exact position is proportional to the scaling number I use, so .25 moves the cursor closer to the corner than .45. Moreover, if I use a value greater than 1, the cursor moves to a different quadrant of my monitor. And, of course, values of 1 leave the cursor in the center of the screen as expected. This just happens on the first mouse input, and the mouse behaves normally after that. I need advice as to how to avoid this cursor movement. It's quite maddening. I also don't think this is strictly a minecraft issue, and I suspect it happens with other java applications that take and release the mouse cursor. Further information, my machine is running Kubuntu 18.04 and openJDK 10.0.2. Edit: Adding more info. I'm starting to notice this behavior in other places during my normal workflow. It's not clear when, but maybe has to do with how KDE is dealing with the mouse events and window focus. I use follow mouse - mouse precedence.

I would like to install Minecraft Education Edition on Linux Mint 22. I have tried using wine and I can get through the installation process but I can't get it to launch. I then tried installing some other things through wine first and I ran "wine Minecraft.Windows.exe" in the terminal and managed to get it to launch but then I get and it is also an older version. I also get the following error 0238:err:ole:create_server class {9052024a-9cde-4aa8-b35f-737bfee80584} not registered 0238:err:ole:com_get_class_object no class object {9052024a-9cde-4aa8-b35f-737bfee80584} could be created for context 0x4 Thank you to whoever helps me with this :)

#### Goal: I'm trying to get a Minecraft server to run on computer boot with systemd on Fedora. I have a few self-imposed criteria that I need to meet to be able to properly manage my server(s): 1. It has to run as the minecraft system user I made with the home dir /opt/minecraft. I attempted this one by addusering and then adding the line User=minecraft and WorkingDirectory=/opt/minecraft/ 2. It has to be scalable and work with an arbitrary number of servers. I attempted this by using a template service and then changing the WorkingDirectory line to WorkingDirectory=/opt/minecraft/%i to let me pass in a directory. 3. I have to be able to pass commands into it somehow. This is the one I'm stuck on. I have tried using a socket unit and then hooking that up to /run/minecraft%I, but I haven't been able to get that to work. If you aren't familiar with Minecraft servers, they have this interactive console thingy that you can pass commands into. In the past, I have used tmux send with the server running in a tmux session, but the issue with that is that it doesn't start automatically and feels inelegant. #### Attempted solution: /usr/local/lib/systemd/system/minecraft@.service:

[Unit]
Description=Minecraft server: %i

# only run after networking is ready
After=network-online.target
Wants=network-online.target

[Service]

# restart if the server crashes
Restart=on-failure
RestartSec=5s

# set the input and outputs to a socket unit and the journal resp.
Sockets=minecraft@%i.socket
StandardInput=socket                     
StandardOutput=journal
StandardError=journal

# set the user and directory to the correct values
User=minecraft
WorkingDirectory=/opt/minecraft/%i/

# run the start script for the specified server
ExecStart=/bin/bash /opt/minecraft/%i/start.sh

[Install]
WantedBy=default.target

/usr/local/lib/systemd/system/minecraft@.socket:

[Unit]
Description=Socket for Minecraft server: %i

[Socket]
# listen to a pipe for input
ListenFIFO=%t/minecraft%I.stdin

Service=minecraft@%i.service

#### Problem: When I try to start the server with sudo systemctl start minecraft@1_17_1.service (I have the server installed in /opt/minecraft/1_17_1/), it fails:

Job for minecraft@1_17_1.service failed because of unavailable resources or another system error.
See "systemctl status minecraft@1_17_1.service" and "journalctl -xeu minecraft@1_17_1.service" for details.

This prompted me to run systemctl status minecraft@1_17_1.service:

I saw that it was seemingly angry with my minecraft@.socket file, so I ran systemctl status minecraft@1_17_1.socket:

#### Question: What am I doing wrong? I have spent 4-ish hours on the *gasp* second, third, and even fourth pages of Google with no solution. I'm at a loss here, so any and all help is greatly appreciated.

I've been running a Minecraft server with a sysV init script. It is a very good script; it runs Minecraft in a "screen"; it can ensure Minecraft is never started twice; and it waits for Minecraft to shut down when stopped. It can even pass a command to Minecraft with /etc/init.d/minecraft command -- this is useful for scheduled backups. Now I've upgraded to Debian Jessie, which has systemd. But for now, I keep my old-style script because it's awesome. Still, I'm actually very supportive of systemd - it really looks like a lot of improvement, simplification and centralization. I remember systemd developers promising that "old sysV scripts will just work as they did before", but turns out it's not so easy! I remember having problems with some startup scripts before; apparently, just putting a script into /etc/init.d and marking it executable is no longer enough - I had to "enable" them in order to make them work. "Well," I thought, "now it's recognized by systemd, and now I can control it via systemctl - and it should probably just use my old script to process the commands!" And turns out I was very much wrong. It doesn't start properly, it doesn't stop properly, it does not display status properly, not to mention the absence of the "command" command. I've started to look for information about how systemd is better than sysV, and what can I do to simplify and empower everything. Apparently, systemctl just makes the simplest unit file possible on its own, and hopes it will suffice! Now I'm wondering if systemd is actually incapable of handling such complex situations at all! I see that an average systemd service basically consists of some requirements and ExecStart. Like it's all systemd needs to monitor the daemon. Type in the conditions and the executable name, and systemd will handle its starting, stopping and who knows what else. But it's not that easy!! You can't just kill Minecraft's PID (not to mention it's different from the screen's PID)! I want to write more complex scripts for every action, maybe even add new actions like "command" (okay, I've already accepted that it's probably not possible at all). For "status", it has to monitor the Java process, and for stop, it has to send a command to the Minecraft console and then wait for both Java and screen to die! I also want to be sure that systemd will not just try to SIGHUP or SIGINT or SIGTERM it! So, what is the slick, modern, "intended systemd way" to do it that really allows us to utilize all the "improvements" and "simplification" systemd gives us? Surely it should be able to handle something more complex than a simple one-process daemon started in a single line and killed with a SIGINT? Should I maybe create a systemd unit and manually specify calling my old script there in every command, like this: ExecStart=/etc/init.d/minecraft start ExecReload=/etc/init.d/minecraft reload (and how do I make the "stop" command and explain how to find the processes to watch for the "status" command?..) I am very pro-innovation, pro-Poettering and pro-systemd in this regard, and I believe there should be a way to do it better than it was before - maybe in an entirely different way, as it usually is with Poettering (which I like about him!). But this doesn't look like much of an improvement - more like a huge regression in need of a huge heap of kludges to even continue as it was before. "sysV scripts will continue working", my ponytail! I can't even be sure if it calls my script to stop Minecraft properly on system shutdown, or just looks at "systemctl status" and sees that it's already "inactive (dead)". Any better ideas?

I have a Minecraft server running on an EC2 Instance (AWS), which runs a Linux (CentOS). I altered the minecraft.service system process to

-ini
ExecStart=python3 run_server.py

This python script pulls a run.json file, which fills in server jar name, webhook URL, role ID, and jvm args. This is what it looks like:

-json
{
  "server_jar":"server.jar",
  "jvm_args":"-Xms1G -Xmx4G",
  "webhook_url":"your_url_here",
  "role_id":"your_role_here"
}

When I run sudo systemctl start minecraft followed by sudo systemctl status minecraft I get this error:

with Popen(*popenargs, **kwargs) as p:  
     ^^^^^^^^^^^^^^^^^^^^^^^^^^^

I'm attempting to get some form of Minecraft Education Edition running on a Linux PC that I have, (Zorin OS 16.1 64-bit). After moving the install files from an existing Windows installation of Minecraft Edu to my Linux PC, I was able to get Minecraft running using Wine (6.0.3)! Unfortunately, the ability to log in doesn't work because Wine doesn't have a suitable implementation for Windows.Networking.Connectivity/Authentication libraries. 0188:err:combase:RoGetActivationFactory Failed to find library for L"Windows.Networking.Connectivity.NetworkInformation" 0024:err:combase:RoGetActivationFactory Failed to find library for L"Windows.Security.Authentication.OnlineId.OnlineIdSystemAuthenticator" A version of wine-staging 5.19 seems to have support for the networking stuff Winehq 5.19 staging notes but I wanted to know what other methods/workarounds the wine community might have before I get my hands dirty with installing and configuring older wine builds. Thanks!

before I explain my issue I should mention that I'm relatively new to Linux so please forgive my ignorance. I'm using an old Dell E10S to act as a dedicated Minecraft server.  I managed to install Linux and a working Minecraft server (downloaded here ). I also was able to get the server to start upon booting the machine by adding a command into the rc.local file in /etc/rc.local. Inside rc.local I wrote: #!/bin/bash sleep 1m cd /home/haven/dw-server/ sudo ./start.sh It worked, but now the server is running in the background when I log in via ssh and I can't type in any server commands like I would on Windows. Does anyone know how I can bring up the server command line when I ssh into my machine? I already tried the fg command.

i usualy play Minecraft on my laptop(4 Go, Intel i5 3320M and Intel HD graphics 4000) using a external usb ssd (on Sparkylinux for have the maximum of ram) and sometime, when i load a world, 5 seconds before, there are very low fps and then it freeze, but all the computer, and i can't do anything. Sometime i wait and Minecraft close itself, sometime the laptop stay in this state for a long time, so i force shutdown (by pressing 5 seconds the on/off button) for restart the system and replay normaly. I made this post for know if there is a other way to shutdown without the risk of corrupting the files or others consequences. Thank you

I want to run the minecraft server.jar with an attached tcp socket, so I use: socat EXEC:"java -jar server.jar nogui" TCP-LISTEN:25567,fork I can connect (and disconnect) to the server without any problems via telnet. But when I stop the server (via /stop) the server terminates (checked with ps auf, the process is definitely gone) but socat just doesn't terminate. How can I start *socat* so it terminates after the EXEC-child is terminated? (I already tried using SYSTEM: instead of EXEC: but that was trying)

Hey i have a raspberry pi with raspbian installed Im wonder if i could use localhost.run which is a website that allows tunneling with ssh could i use this with a mc server looking to run java edition if would it be secure and would it be reliable?

I'm running a Minecraft Bedrock server for my kids on an Almalinux VPS. It's not exactly supported but it runs. It shuts down about twice a day. I'm trying to automate the restarting of the server. I have a cron job that runs every minute, which is intended to restart the server. The command line to restart works if I execute it from terminal, but not from crontab. The echo message gets delivered to me by email, so the script itself is executing. I've tried several iterations of the screen command, including writing a log file, which doesn't get created. My crontab entry: * * * * * root /bin/bash /home/mcserver/minecraft_bedrock/restart.sh My file, restart.sh: #!/bin/bash ps_out=ps -ef | grep bedrock_server | grep -v 'grep' | grep -v $0 result=$(echo $ps_out | grep bedrock_server) if [[ "$result" == "" ]]; then echo "attempting restart" screen -d -m /home/mcserver/minecraft_bedrock/bedrock_server fi I appreciate any guidance in the right direction! EDIT: After trying some more things, I was able to get my script to work. I'm not going to answer the question myself, because I think there are some things I don't understand, and I'd like to award the answer to the user who explains how to use screen, or why it's not working. In the code below (working), I've commented out what I tried that did not work (using screen and tmux). I made some traction just trying to execute the startup file, ./bedrock_server, but I previously got errors telling me I needed to use a terminal, which is what led me to use screen to begin with. Based on my latest errors, I determined that I needed to change directory to the absolute directory, then execute ./bedrock_server. Below is the working code: #!/bin/bash ps_out=ps -ef | grep bedrock_server | grep -v 'grep' | grep -v $0 result=$(echo $ps_out | grep bedrock_server) if [[ "$result" == "" ]]; then # screen -d -m /home/mcserver/minecraft_bedrock/bedrock_server #tmux new-session -d -s mc_session '/home/mcserver/minecraft_bedrock/bedrock_server' cd /home/mcserver/minecraft_bedrock/ ./bedrock_server fi

I'm trying to run Minecraft on NixOS with Sway, and the launcher works fine but every time I want to launch the game it shuts down and the launcher displays an error message with exit code 0. I've got jdk11, jk8 and jre8 installed.

In my laptop's touchpad double tap with two fingers only work single time in Minecraft as well as on desktop/Home i.e single right-click , but in Minecraft it do not hold with two finger double tap or even holding with two fingers, i can't eat my cooked food. Although I have gnome tweaks installed.

Lately I've been trying to experiment with some linux distributions, then try to play games there such as minecraft. I tried: 1. Manjaro - Lag 2. Drauger OS (It said for game) - Still lag 3. MX Linux - Really-really smooth I could use MX Linux as the main distribution. However, because a lot of information says that some of the most Ubuntu packages can't run on MX Linux, I'm also hesitant to use it. Can someone explain why minecraft is running so efficiently on MX Linux. Because I want to configure the same settings on Ubuntu to run smoothly like MX Linux. I think that this is a matter of drivers or kernel compatibiliy, but I'm not sure because there are many factors that determine linux performance. Spec: $ lsb_release -a No LSB modules are available.

Really don't know what to do about this one. I'm trying to start a minecraft server with more RAM but the commands in the terminal give me this error. The server works only if I go to the file manager and click on the server.jar file, it then boots up like normal with the GUI and everything. The problem is that I can't set RAM parameters through there, only through commands. I've tried: `sudo java -Xmx1024 -Xms1024 -jar server.jar` `sudo java -Xmx4096 -Xms1024 -jar server.jar` `sudo java -Xmx8164 -Xms1024 -jar server.jar` `sudo java -Xmx1000000 -Xms1024 -jar server.jar` `sudo java -Xmx3072 -Xms2048 -jar server.jar` `sudo java -Xmx2048 -Xms512 -jar server.jar` `sudo java -Xmx1024 -Xms512 -jar server.jar` `sudo java -Xmx512 -Xms256 -jar server.jar` All result in the exact same error every time: "Error occurred during initialization of VM" "Too small maximum heap" I've tried these with -nogui too, same error.

I manage a Linux server for my friend which runs a Minecraft server, I consider myself a total noob in Linux but i know how to work with it a little. Since the server is at my friend's house I use powershell to ssh into the server and start the startup script inside a screen. But after a while a process starts running /bin/dhcpcd and it always uses at least 50% of the CPU power. It also starts when I don't start the minecraft server but it never runs at startup. What is this, can I disable it and if so how?

I have a keyboard input bug in Minecraft 1.12 and below. When I open a world I can use only number keys, arrows and special keys(functional keys, escape etc). I wrote a mod that writes the name and code of the button when it is pressed and it does not respond to press on buttons with letters on they. I think Minecraft response buttons wrong. My system: Fedora 35, KDE Plasma 5.24.3, X11 1.20.14

When I try to install Mods on GDLauncher, it sometimes stays at 0%. It will not change after left for about 20 minutes. I am using an unofficial bin launcher since that is the only way I can do it. I have tried closing and reopening. I also prefer not getting an answer about uninstalling and reinstalling the app since I do not remember the password. Here is a provided image for reference. If there is anything wrong with my question please tell me so I can fix it. Thanks.
