Are you running Wireshark on the Raspberry Pi?

Yes is that a bad idea

No, but there's a difference between "I'm trying to run Wireshark on a Raspberry pi and I can't capture packets" and, for example, "I have a network with a Raspberry pi on it, and I'm running Wireshark on some other machine and it's not capturing traffic from the Raspberry pi", so I wanted to make it clearer what the precise problem was.

Are you getting an error if you try to capture packets, or is it just running but not capturing any packets?

Hi,

You probably need elevated privileges to see the interfaces in "Raspbian".

I suggest you read this article.

https://wiki.wireshark.org/CaptureSetup/CapturePrivileges

By installing Wireshark packages non-root users won't gain rights automatically to capture packets. To allow non-root users to capture packets follow the procedure described in the Wireshark debian/README.Debian file.

You should be able to follow Debian instructions.

Cheers,

JF
