wireshark: no interface can be used for capturing in this system
ubuntu14.04下使用wireshark找不到网卡。。。
解决方法:
Open a terminal by pressing Ctrl+Alt+T and type the following commands:
sudo dpkg-reconfigure wireshark-common
press the right arrow and enter for yes
sudo chmod +x /usr/bin/dumpcap
you should now be able to run it without root and you will be able to capture.
