Ubuntu set normal user execution permissions after Wireshark

1. Add Wireshark user Group
 
sudo groupadd wireshark
 
2. Change Dumpcap to Wireshark user group
 
sudo chgrp wireshark/usr/bin/dumpcap
 
3, let Wireshark user group have root permission to use Dumpcap
 
sudo chmod 4755/usr/bin/dumpcap 
 
(Note: If set to 4754 Wireshark will still prompt for no permissions)
 
4, will need to use the ordinary user name to join the Wireshark user group, my user is "Dengyi" (need to modify according to the specific user name!) ), you need to use the command:
 
sudo gpasswd-a dengyi wireshark 
 
This completes, with the ordinary user Dengyi login open Wireshark will have permission to grab the packet.
