Minecraft server properties

Key	Type	Default Value	Description
allow-flight	boolean	false	Allows users to use flight on your server while in Survival mode, if they have a mod that provides flight installed.

max-players	integer (0-999)	20	The maximum number of players that can play on the server at the same time. Note that if more players are on the server it will use more resources. Note also, op player connections are not supposed to count against the max players, but ops currently cannot join a full server.
motd	string	A Minecraft Server	This is the message that is displayed in the server list of the client, below the name. Note, motd does NOT support color codes. If the MOTD is over 59 characters, the server list will likely report a communication error.
online-mode	boolean	true	Server checks connecting players against minecraft's account database. Only set this to false if your server is not connected to the Internet. Hackers with fake accounts can connect if this is set to false! If minecraft.net is down or inaccessible, no players will be able to connect if this is set to true. Setting this variable to off purposely is called "cracking" a server, and servers that are presently with online mode off are called "cracked" servers. true - Enabled. The server will assume it has an Internet connection and check every connecting player. false - Disabled. The server will not attempt to check connecting players.
pvp	boolean	true	Enable PvP on the server. Note: Hitting a player while having PvP set to false and having tamed wolves will still cause the wolves to attack the player who was hit. true - Players will be able to kill each other. false - Players cannot kill other players (Also called PvE).

spawn-animals	boolean	true	Determines if Animals will be able to spawn. true - Animals spawn as normal. false - Animals will immediately vanish. Tipp: if you have major lag, turn this off/set to false.
spawn-monsters	boolean	true	Determines if monsters will be spawned. true - Enabled. Monsters will appear at night and in the dark. false - Disabled. No monsters. Unless your difficulty is not set to 0, when a monster can still spawn from a Monster Spawner. Tipp: if you have major lag, turn this off/set to false.

view-distance	integer (3-15)	10	Sets the amount of world data the server sends the client, measured in chunks in each direction of the player. It determines the server-side viewing distance. The "Far" viewing distance is 9 chunks. 10 is the default/recommended. Tipp: if you have major lag, reduce this value.
white-list	boolean	false	Enables a white list on the server. With a white list enabled, users not on the white list will be unable to connect. Intended for private servers, such as those for real-life friends or strangers carefully selected via an application process, for example. Note - Ops are automatically white listed, and there is no need to add them to the whitelist. false - No white list is used. true - The file white-list.txt is used to generate the white list.
