参考https://blog.csdn.net/wilsonpeng3/article/details/47209915

安装后打开wireshark 提示权限不足消息:

Couldn’t run /usr/bin/dumpcap in child process: Permission denied

解决方案

~$ sudo groupadd wireshark
groupadd: group 'wireshark' already exists
~$ sudo usermod -a -G wireshark you-user-name
~$ newgrp wireshark
~$ sudo chgrp wireshark /usr/bin/dumpcap
~$ sudo chmod 754 /usr/bin/dumpcap
~$ sudo setcap cap_net_raw,cap_net_admin=eip /usr/bin/dumpcap
