Would like to forcefully kick a specific user connection.

OS is Ubuntu 16, OVPN Server is OpenVPN 2.3.10

I can see them connected in /etc/openvpn/openvpn-status.log which lists out current client status. And their persistent connection pool is saved to /etc/openvpn/ipp.txt

I can kick all users by simply cycling the openvpn daemon service openvpn restart however I want to kick ONE single user.

I've tried openvpn --help and man openvpn as well as searched google but not seeing anything.

OS is Ubuntu 16, Server is OpenVPN 2.3.10

Doing this requires some preparation ahead of time. Specifically you need to enable the Management port (--management IP port). With the management port enabled you can connect to that management port using telnet/netcat and then you can issue commands to disconnect a session (eg kill client-name).

See this page for more about the usage of that interface.

  • This is a brute force solution and not a great user experience. Because you only kill the connection. The user still believes to be connected to the server. Ideally a disconnect signal should be sent to the user so that the client disconnects properly.
