# Sniffer Tab

## How to sniff?

It’s simple. For every discoverd interface you can find a sniffer tab here. If no tab for your desired interface is displayed, please re-check all available interfaces using the button on the main tab. Once you find your desired interface, just click on start.

## Ignoring packets

You can add tab specific packets to the ignore list. Hint: Use a blank data field if you want to exclude whole IDs.

Another Hint: You can use the fitering buttons to remove background noise. It’s great.

## I get errors/no data when I try to sniff!!1!

> - Maybe your SocketCAN interface disappeared?

> - Maybe you have selected a wrong bitrate?

> - Have you tried turning it off and on again?

## The sniffer tab doesn’t list the packets I’m sending

Thats normal. You will only see packets that you are receiving on a specific interface. This prevents the packets that you generate via fuzzing from being in your sniffed dump. If you really need all packets in one dump, you can use `candump`.
