An Intro. My son said he'd like a Minecraft server. I rented a 4GB 2CPU instance yesterday using the Ubuntu Minecraft 1.15.2 image, I put the UFW firewall up and opened both TCP and UDP to the default game and rcon ports, enabled rcon, gave it a password. I've allowed 200 players, he wants to get his school playing. I changed the systemd start command to give 3GB to the java run line and it now says ExecStart=/usr/bin/screen -DmS mc-%i /usr/bin/java -Xmx3G -jar minecraft_server.jar nogui I do not know the slightest bit about gameplay, when I log in I just stand there, dig a hole and fall in. The boy can repeat what I did to build the server now that he's seen it done. So, I can rcon in with linux mcrcon and /op the boy, he knows what to do with the op status. I can list and see him. He can play. All of that works. Will his op status continue past a reboot or do I have to do something more? Is the hardware going to handle 200 players? I have no idea when to scale anything. Where do I look for mods? He says there's mods. I'm wary about security and about who writes them but that's just ignorance. What would I like to have known once I know more. Is there a performance implication? Is it true that only people with java edition can use the server? Only people running 1.15.2? It makes no difference whether they're on android, linux, Mac or Microsoft Windows™?

Hey Ryan, Would it be possible to get the Control Panel to show the current version, like the ARK ones do? So I can be sure if a small update went through properly, etc. Thanks! k

Hello all, after not playing for a few days I finally got a chance to play again but on my control panel it says "ARK Version 243.0" but my game is up to date at 242.9 and from a little bit of research it doesn't appear that 243.0 is even released yet. This is keeping me from connecting to the server with the "unable to query server info for invite" message. Is anyone else experiencing this? and is there any way to fix it? Thanks- Decidus
