Ah – a common problem. Wireshark has installed and does not see any of the computer interfaces so you can do captures.
The answer to your problem is simple!
Open a terminal and enter the following commands in order (you can skip the first one if you already have Wireshark installed):
sudo apt install wireshark
sudo dpkg-reconfigure wireshark-common
You will be prompted to allow users to access dumpcap – select OK/Yes.
sudo usermod -a -G wireshark $USER
sudo reboot
Some would argue the reboot is not necessary, that you just need to log out and back in.
Run Wireshark and the interfaces should be there!!
Watch out for possible misunderstanding about names of these interfaces, sometimes they are simple like the old legacy names:
eth0,eth1– Ethernetwlan0,wlan1– Wirelesslo– Loopback (unchanged)
Today they look like this:
- PCI path
enp3s0→ Ethernet, PCI bus 3, slot 0wlp2s0→ Wireless, PCI bus 2, slot 0
- On-board index
eno1→ On-board NIC #1
- MAC-based (fallback)
enx78e7d1ea46da→ Based on MAC address
