“No interface can be used for capturing in this system with the current configuration.”.
The following steps will rectify this.
sudo usermod -a -G wireshark zhangbin
sudo chgrp wireshark /usr/bin/dumpcap
sudo chmod 777 /usr/bin/dumpcap
sudo setcap cap_net_raw,cap_net_admin=eip /usr/bin/dumpcap
sudo getcap /usr/bin/dumpcap
要改成777，之前是750，否则会无权限：
