Hey linux community I got a question? Does anyone here know a little bit about hosting a simple minecraft server on Debian 10.6 on your PC?. My son likes minecraft and likes to play on my computer once in awhile and he asked me if I knew how to make his own server so I'm in the middle of that right now but need some help with safety precautions I went ahead and made a user " su minecraft " with no password so people can't ssh connect does anyone know how to edit the sudoers file permissions for the minecraft user? to where I don't need to use sudo? thank you for taking your time and reading not in a hurry to get this done so take your time if your helping or working with someone else.

My grandson uses minetest in the Debian buster repositories and likes it as well as minecraft (he plays with both).

yeah it definitely keeps him busy I wonder how your grandson secures his server and how he sets his sudo permissions with the sub user the server is running under has for safety reasons has the server will be available online to other players so I dont want people able to mess with our network plus his server and settings.

The minecraft user shouldn't need any sudo permissions. You can install java as root, put the jar file in the Minecraft user's home directory, then execute it with as the minecraft user.

Again, minetest is apparently just as good as minecraft. Grandson says there is little difference.

I have it configured as a service so it restarts with the machine and you can do sudo service minecraft start/stop/status


In the file "/etc/systemd/system/minecraft.service" I have :

[Unit]
Description=minecraft service.
After=network.target
StartLimitIntervalSec=0[Service]

[Service]
Type=simple
Restart=always
RestartSec=1
User=alex
WorkingDirectory=/home/alex/minecraft
ExecStart=java -Xmx1024M -Xms1024M -jar /home/alex/minecraft/server.jar nogui
#StandardOutput=/home/alex/minecraft/log.txt
#StandardError=/home/alex/minecraft/log.txt

[Install]
WantedBy=multi-user.target

If you need to ask questions like that, don't do it.
Get aquainted with Debian stable first, then with running a server in general, and securing it.

No, it's not even close.

I think you have chosen not a very good option to create. This is a rather complex service
My friend tried to make the server this way, but it did not work out as there was a need for additional knowledge that he did not have. I do not understand anything in this area , but I know a little about it and my friend and I were advised https://minecraftservers.biz/cubecraft/ which we played without problems, thus replacing what my friend tried to do. Thus, we still managed to play a kind of server on which we could play without interruption and together, as if it were our local server , and when we were tired of surviving together, we went to the rest of the games and got acquainted with others.

I think you are taking a large risk if you are running a minecraft server and allowing people outside your own LAN to connect.

The suggestion to educate yourself about running a server and securing it is something you need to take to heart.

Wow, is it really difficult to make your own Minecraft server on Linux?! That's why I'm only working on Linux and not trying to install any games on this operating system. To be honest, I have never set up a server for Minecraft on Linux. However, I did it on Windows. And you have several options. One of them is just to open the ports using the settings in your wifi adapter. The second way is to simply purchase to pay for server rent, and the third is to tell your child to try to play on some large minecraft prison servers that he will be interested in (at least my son really likes such servers)

Managing a server of any type that allows outside connections requires the admin to have a thorough knowledge of security and how to protect his system (and network). Failing that it is only a matter of time until some cracker manages to own the machine (and the network as well).

If the machine is only accessible from within the LAN it does reduce the risk, but does not eliminate it.

Yeah...9 whole steps:

And gaming on Linux has come a long way.

You may be better served by using a prebuilt docker for it. There are tons of them on docker hub. I know I made one myself and use it daily. But opening to the internet is a whole can of worms you may not be up for. In that case it's both safer, and likely cheaper to just pay for a realms sub or renting a server. They are dirt cheap these days for what they offer in regards to proper system admin and security. https://www.g-portal.com/us/en/games...MaAl3lEALw_wcB is one such place. I can't speak to this one's quality but they are everywhere.
