# Main Tab

Welcome to CANalyzat0rs main tab! Here you can change interface settings and creat/remove virtual CAN interfaces. Don’t worry, the kernel modules should aready be loaded for you.

## Where’s my interface?!?!1!

If you can’t find your attached CAN interface in the ComboBox, please check the output of `ifconfig -a`. In order to use your interface with CANAlyzat0r, a SocketCAN device must be present. Maybe you have to load another kernel module/driver?

## Creating and selecting projects

On a fresh startup, you should encounter a message saying that a new project should be created. You can still use this application without a selected project. However, one can’t save dumps or known packets. To create a project, please refer to the manager tab. After you have created a project there, you can set it as active project in the main tab.

## Log levels

You can set the minimum log level for which messages will be printed to the log box in this tab.

## Where’s my data being saved to?!!?

By default, CANalyzat0r creates a SQLite database called “database.db” in the data folder. Please take care of this file as everything you discover is saved here.

## But what if i want to export my data?

Please check the manager tab and learn on how to export projects and dumps.
