Description

This mod adds per user IP based authorization.

This mod is very useful for offline mode Minecraft servers because it ensures that a user with a username can only join from a specified IP. This avoids impersonating other users and stealing their dear resources.

Commands

/ipauth add player

Register a player with specify IP addresses the player can join with.

/ipauth add player ip1 ip2 ip3 ...

Remove a player completely.

/ipauth remove player

Remove IP addresses the player can join with.

/ipauth remove player ip1 ip2 ip3

Set auto_auth property from the game.

/ipauth setautoauth true|false

Set use_uuid property from the game.

/ipauth setuseuuid true|false

Get general information.

/ipauth info

Get info on a IP or a user.

/ipauth info IP|user

The config is in JSON format.

  "USERNAME": ["IP 1", "IP 2"]
 },
 auto_authorize: true, // on first join, automatically register the user to authorized list with the joining IP. (will be auto_auth on next release)
