Editing Server (section)

== Managing and maintaining a server ==
{{see also|Tutorials/Server maintenance}}

Servers are generally managed by '''administrators''' and '''operators'''. The administrator generally takes responsibility for the server. It may be that the server is running from their machine, or that they simply have jurisdiction over a server. Operators generally assist the administrators to moderate a server and to prevent unruly players and griefers. Both operators and administrators have access to various [[commands]] in order to ensure the smooth running of the server. On a default server, players are assigned as operator or administrator by using the {{command|op|<playername>}} command, or by editing the <code>ops.json</code> in the server directory, then restarting the server.

Local servers do not strictly require access to minecraft.net, and so can be played on an isolated local network with no internet connection. They use minecraft.net as a repository of player skins and also a database containing a list of accounts, preventing hackers and griefers from using false names while on such a server. This and other settings are modified by editing the [[server.properties]] text file.

The server saves the level in the "world" folder every 30 seconds if chunks have been modified, by default.

=== Kick messages ===
Kick messages are messages that are displayed when an operator kicks the player, or the player has issues connecting to the server.

* '''End Of Stream''' (Client message) – The server has stopped sending data to the client
* '''Internal Server Error:java.net.Minecraft''' – The server is sending unknown information to the client, usually from a [[Mods#Server-based|server mod]], this happens with a client with an outdated mod tries to join the server with the updated mod.
*'''Timed Out''' - The client has lost connection to the server, most likely due to disconnecting from the Internet or having Minecraft features blocked by a firewall.
* '''Internal exception: java.io.IOException: Received string length longer than the maximum allowed (''[Number]''>256)''' – A chat message that the client sent to the server exceeded the maximum character limit.
* '''Internal Server Error''' – The server generated an exception when handling the client's request.
* '''Disconnected''' - The player disconnected by using the Disconnect button in the Main Menu
