我正在使用 charon-cmd 连接到 ubuntu 主机上的 strongswan vpn。当我使用该命令时，它给出了某种权限错误。

我正在 Docker 容器上执行此操作。
我尝试了 setcap，但这使情况变得更糟。
root@8add2362b05f:~# setcap cap_net_admin,cap_net_raw=eip /usr/sbin/charon-cmd
root@8add2362b05f:~# getcap /usr/sbin/charon-cmd /usr/sbin/charon-cmd = cap_net_admin,cap_net_raw+eip
root@8add2362b05f:~#
root@8add2362b05f:~#
root@8add2362b05f:~# sudo charon-cmd --host example.com --p12 ipsec_vpn_vert/client.cert.p12 --identity [email protected]
sudo: unable to execute /usr/sbin/charon-cmd: Operation not permitted

关于如何解决这个问题有什么线索吗？
答案1
我认为您应该使用 --privileged 选项运行 Docker 容器。或者您可以使用 VM 而不是 Docker 容器。
