Turtle modules may be started, stopped, enabled, disabled or configured from the Module Menu. ### CONFIGURE Configuring a module typically involves entering data specific to your deployment. For example, when configuring the Meterpreter module, you must specify the listening host and port. When configuring the Nmap module you must specify a target, profile and log. Configuration changes made through the graphical Turtle Shell are generally saved in config files and are persistent upon reboot. ### START / STOP Once configured, a module may be Started or Stopped from the Module Menu. Generally a module may not be started until it has been configured. Some modules, such as the SSH Key Manager, do not support starting and only allow for configuration. Some modules stay running once started. For instance the autossh module will maintain a persistent secure shell until stopped. Other modules will start a task then stop when completed, such as script2email or nmap-scan. ### ENABLE / DISABLE Modules may be set to start up once the LAN Turtle has booted. For example an OpenVPN session may be established upon power-up by first configuring the module and testing it using the start and stop feature. Once the module is achieving the desired result, the module may be Enabled from the Module Menu. Now the LAN Turtle can be deployed on a target network with the OpenVPN module establishing a connection without intervention from the user. An enabled module will start on every boot unless disabled from the Module Menu. ### ADDITIONAL MODULES The LAN Turtle is designed to enable rapid module development. Any supported language (such as bash, php, or python) may be used to write a Turtle Module. With just a few core functions required, modules may be quickly developed and tested. Once submitted to the LAN Turtle Module Repository, they may become available for other LAN Turtle users to download and enjoy.
