如何在Fedora Docker上使用'ping‘
如何在Fedora Docker上使用'ping‘
提问于 2019-04-12 08:06:07
在容器根/目录中，我键入
ping并获取
bash: ping: command not found然后我输入
yum install iputils然后我输入
ping我得到了
bash: /usr/bin/ping: Operation not permitted那我就这么做
sudo ping我得到了
bash: sudo: command not found所以我输入
yum install sudo然后我输入
sudo ping我得到了
sudo: unable to execute /bin/ping: Operation not permitted在这一点上，我放弃了，把我的手抛向空中...
那么，我如何使用ping util，并且我还想使用hostname和ifconfig等其他实用程序

安装*iputils后，应设置CAP_NET_RAW功能：
sudo setcap cap_net_raw+p /bin/ping默认情况下，
用户没有CAP_NET_RAW。
