XX XX - length of following string, in characters, as a short.Compute as 7 + len(hostname), where len(hostname) is the number of bytes in the UTF-16BE encoded hostname. XX XX - length of the rest of the data, as a short.00 0B - length of following string, in characters, as a short (always 11).FA - packet identifier for a plugin message.01 - server list ping's payload (always 1).FE - packet identifier for a server list ping.Instead of doing auth and logging in (as detailed in Protocol and Protocol Encryption), it sends the following data, expressed in hexadecimal: The client initiates a TCP connection to the server on the standard port. Modern servers recognize this protocol by the starting byte of fe instead of the usual 00. This uses a protocol which is compatible with the client-server protocol as it was before the Netty rewrite. If you are client side, bind a UDP socket and listen for connections. To implement it server side, just send a packet with the text (payload) to 224.0.2.60:4445. The IP Address is the same as the senders one. If it is out of range, an error is being displayed when trying to connect. If it is not numeric, 25565 will be used. Anything you write outside of each of the tags will be ignored. Minecraft seems to check for the following Strings:,. The JSON Response field is a JSON object which has the following format: See below as with all strings this is prefixed by its length as a VarInt(2-byte max) Note that Notchian servers will for unknown reasons wait to receive the following Ping Request packet for 30 seconds before timing out and sending Response. The server should respond with a Status Response packet. The client is also able to skip this part entirely and send a Ping Request instead. The client follows up with a Status Request packet. Should be 1 for status, but could also be 2 for login. The Notchian server does not use this information. if _minecraft._ points to mc., users connecting to will provide mc. as server address in addition to connecting to it.ĭefault is 25565. Note that SRV records are a complete redirect, e.g. localhost or 127.0.0.1, that was used to connect. See Protocol version numbers for a list of valid protocol versions. Setting invalid (nonexistent) version as the protocol version might cause some servers to close connection after this packet If the client is pinging to determine what version to use, by convention -1 should be set. The version that the client plans on using to connect to the server (which is not important for the ping). For the general packet format, see that article.įirst, the client sends a Handshake packet with its state set to 1. This uses the regular client-server protocol. 1.6 Ping via LAN (Open to LAN in Singleplayer).
