broctl — interactive shell for managing Bro installations


broctl [command]


broctl is an interactive interface for managing either a standalone or a Bro cluster installation.  If a broctl command is specified directly on the command-line, then broctl performs the action associated with that command immediately (instead of running the interactive interface).

Before actually running broctl you first need to edit the broctl.cfg, node.cfg, and networks.cfg files. In the broctl.cfg file, you should review the broctl options and make sure the options are set correctly for your environment. Next, edit the node.cfg file and specify the nodes that you will be running. Finally, edit the networks.cfg file and list each network that is considered local to the monitored environment (see the examples in the file for the format to use).

When running broctl for the first time, you must run the broctl deploy command before running any other commands in order to apply the configuration settings.  You must also run broctl deploy each time you change the configuration (including any Bro scripts) or upgrade Bro.
