Server.properties



Server.properties is the file which stores all the settings for a multiplayer server.

If you are going to edit server.properties it is important that you use the same structure as the original uses. The text before the equal sign is the key, which you shouldn't change. The text after the equal sign is the key's value, which you can edit. Lines that begin with  are comments.

You need to restart your server if you change the settings file for the new changes to take effect.

verify-names
If enabled the server will make sure that the client is logged in with the same IP on Minecraft.net. This has caused problems for people trying to play on the same computer they are hosting the server on as the server will see the local IP 127.0.0.1) while Minecraft.net will see the external IP. It is recommended that this is enabled unless you want to play n your server from the same computer you are hosting it on
