Solve Wireshark permission problems in Ubuntu

Wireshark must monitor eth0, but it must have the root permission. However, running the program directly with root is quite dangerous and inconvenient.

The solution is as follows:
1. Add Wireshark User Group

Sudo groupadd Wireshark

2. Change dumpcap to Wireshark User Group

Sudo chgrp Wireshark/usr/bin/dumpcap

3. Grant the wireshark user group the root permission to use dumpcap.

Sudo chmod 4755/usr/bin/dumpcap

4. Add the username to the wireshark user group. My username is craftor.

Sudo gpasswd-A craftor Wireshark
