Make sure that Wireshark can sniff packets without running as a root. This information tells us all what we need to know.

me@VM:~$ less /usr/share/doc/wireshark-common/README.Debian

so when we have read this we do:

me@VM:~$ dpkg-reconfigure wireshark-common
me@VM:~$ sudo usermod -a -G wireshark me

You should have typed {yes} when doing the reconfigure and substituted "me" with your {own username}.

Reboot your machine, log in, and start wireshark. you should see the following screen. Notice "vcan0"

start capturing the vcan0 interface by selecting the vcan0 interface and clicking start.

Open a terminal and give the following command:

me@VM:~$ cansend vcan0 001#04.01.00.00.0f.ff.e7.00

Return to Wireshark and note that the you see the communication.
