|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.|

|difficulty||integer (0-3)||1||Defines the difficulty (such as damage dealt by mobs and the way hunger and poison affects players) of the server.|
- 0 - Peaceful
- 1 - Easy
- 2 - Normal
- 3 - Hard

|generator-settings||string||blank||The settings used to customize Superflat world generation. See Superflat for possible settings and examples.|
|hardcore||boolean||false||If set to true, players will be permanently banned if they die.|
|level-name||string||world||The "level-name" value will be used as the world name and its folder name. You may also copy your saved game folder here, and change the name to the same as that folder's to load it instead.|
- Characters such as ' (apostrophe) may need to be escaped by adding a backslash before them.
|level-seed||string||blank||Add a seed for your world, as in Singleplayer.|
- Some examples are: minecraft, 404, 1a2b3c.
|level-type||string||DEFAULT||Determines the type of map that is generated.|
- DEFAULT - Standard world with hills, valleys, water, etc.
- FLAT - A flat world with no features, meant for building.
- LARGEBIOMES - Same as default but all biomes are larger.
- AMPLIFIED - Same as default but world-generation height limit is increased.
- CUSTOMIZED - Since snapshot 14w21b, servers also support the custom terrain. First you have to generate a customized world in singleplayer and copy it to the server.
|max-build-height||integer||256||The maximum height in which building is allowed. Terrain may still naturally generate above a low height limit.|
|max-players||integer (0-2147483647)||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. Extremely large values for this field result in the client-side user list being broken.|
|integer (0-29999997)||29999997||This is the maximum possible size that the world border will be when using the worldborder command. Even if the World border is set bigger, it will not expand past this many blocks from the world's origin (0,0)|
|motd||string||A Minecraft Server||This is the message that is displayed in the server list of the client, below the name.|
- The MOTD does support color and formatting codes.
- If the MOTD is over 59 characters, the server list will likely report a communication error.
|integer||256||By default it allows packets that are n-1 bytes big to go normally, but a packet that n bytes or more will be compressed down. So, lower number means more compression but compressing small amounts of bytes might actually end up with a larger result than what went in.|
- -1 - disable compression entirely
- 0 - compress everything
Note: The Ethernet spec requires that packets less than 64 bytes become padded to 64 bytes. Thus, setting a value lower than 64 may not be beneficial. It is also not recommended to exceed the MTU, typically 1500 bytes.
|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, allowing players with unlicensed copies of Minecraft to join.|
- 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.
|op-permission-level||integer (1-4)||4||Sets permission level for ops.|
- 1 - Ops can bypass spawn protection.
- 2 - Ops can use /clear, /difficulty, /effect, /gamemode, /gamerule, /give, and /tp, and can edit command blocks.

- 7 (0x7) UseEntity
|pvp||boolean||true||Enable PvP on the server. Players shooting themselves with arrows will only receive damage if PvP is enabled.|

- true - Players will be able to kill each other.
- false - Players cannot kill other players (also known as Player versus Environment (PvE)).
|query.port||integer (1-65534)||25565||Sets the port for the query server (see enable-query).|
|rcon.password||string||blank||Sets the password to rcon.|
|rcon.port||integer (1-65534)||25575||Sets the port to rcon.|
|resource-pack||string||blank||Server prompts client to download resource pack upon join. This link must be a direct link to the actual resource pack .zip file.|

- Set to blank, or the IP you want your server to run (listen) on.
|server-name||string||Unknown Server||The name of your server.|
|server-port||integer (1-65534)||25565||Changes the port the server is hosting (listening) on. This port must be forwarded if the server is hosted in a network using NAT (If you have a home router/firewall).|
|snooper-enabled||boolean||true||Sets whether the server sends snoop data regularly to http://snoop.minecraft.net.|
- false - disable snooping.
- true - enable snooping.
|spawn-animals||boolean||true||Determines if animals will be able to spawn.|
- true - Animals spawn as normal.
- false - Animals will immediately vanish.
Tip: 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.
This does nothing if difficulty = 0 (peaceful) Unless your difficulty is not set to 0, when a monster can still spawn from a Monster Spawner. Tip: if you have major lag, turn this off/set to false.
|spawn-npcs||boolean||true||Determines if villagers will be spawned.|
- true - Enabled. Villagers will spawn.
- false - Disabled. No villagers.
|spawn-protection||integer||16||Determines the radius of the spawn protection. Setting this to 0 will not disable spawn protection. 0 will protect the single block at the spawn point. 1 will protect a 3x3 area centered on the spawn point. 2 will protect 5x5, 3 will protect 7x7, etc. This option is not generated on the first server start and appears when the first player joins. If there are no ops set on the server, the spawn protection will be disabled automatically.|
|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 (radius, not diameter). It determines the server-side viewing distance. The "Far" viewing distance is 16 chunks, sending 1089 total chunks (the amount of chunks that the server will load can be seen in the debug screen). "Normal" view distance is 8, for 289 chunks.|
10 is the default/recommended. If you have major lag, reduce this value.
|white-list||boolean||false||Enables a whitelist on the server.|
With a whitelist enabled, users not on the whitelist 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.
