Welcome to the wiki of the CAPTURino plugin!
The executable of the plugin can be copied to one of the following folders:
- Global Extcap path: All users who can use wireshark can use the plugin (Admin rights are probably necessary to move the plugin to that folder)
- Personal Extcap path: Only the current user can use the plugin with wireshark The exact paths can be found in Help > About Wireshark > Folders
Beware that the plugin must have access to serial ports to be able to communicate with an embedded device. On linux devices it might therefore be necessary to add the user, who wants to use the plugin, to the group dialout. This can be done with the command sudo usermod -a -G [groupname] [username].
Once the plugin is installed and recognized by Wireshark, it can be configured in Wireshark's UI by clicking on the gearwheel on the left-hand side of the plugin name. First, the connection to the CAPTURino embedded device must be configured. Therefore, it is mandatory to specify the serial port, the baudrate and the capture interface to be used. The serial port can be selected from the drop down menu. The baudrate depends on the application and driver software of the CAPTURino device. Please refer to the documentation of the application or driver software to find the correct setting of it. Once the serial port and baudrate are configured correctly, a click on the Reload button next to the setting Capture interface will update the list of available capture interfaces. Please note that this list will show only the capture interfaces supported by the CAPTURino device.
Optionally, a logfile can be created during capturing. If no logfile is needed, the setting can be left untouched.
Depending on the capture interfaces supported by the plugin, there are other tabs to configure parameters specific to the supported capture interface.
If the configuration of the plugin is finished, either a double click on the interface, or a click on Wireshark's blue fin in the top left corner of the toolbar, will start the capture process.
Wireshark supports to filter data packets by some properties. Information about this feature can be found in Wireshark's Display Filter Reference
