Configuration File

Most of the server global parameters are set in the XML configuration file. On Linux platforms the path to the file is /opt/traccar/conf/; on Windows the path can be changed during the installation process, but by default it should be in C:\Program Files\Traccar\conf. Configuration file can be edited using any text editor. Please make sure it's a valid XML file and special characters are escaped.

Some of the parameters are configured via attributes on Device, Server and other objects through the web app. Check the badge next to an attribute key for information on where the parameter can be used.

For boolean (true/false) values, if the value is not specified the server treats it as false.

List of available configuration parameters:

[protocol].address config

Network interface for a the protocol. If not specified, server will bind all interfaces.

[protocol].port config

Port number for the protocol. Most protocols use TCP on the transport layer. Some protocols use UDP. Some support both TCP and UDP.

If true, the server expects locations to come at random order (since tracking device might go offline). Filter checks for duplicates, distance, speed, or time period against the preceding Position's. Important: setting to true can cause potential performance issues.
