Fedora下安装使用Wireshark问题
安装后启动wireshark遇到问题报错如下:
Couldn't run /usr/sbin/dumpcap in child process: Permission denied Are you a member of the 'wireshark' group?
Try running 'usermod -a -G wireshark _your_username_' as root.
但结果还是不能运行,此时你需要使用如下newgrp更新你的group id,如:
newgrp wireshark
如此新的建立的shell将可以使用新加入的组wireshark,如果不行,可能还需要注销再登陆下即可。
