10. Using the Management Interface

The OpenVPN management interface allows a great deal of control over a running OpenVPN process. You can use the management interface directly, by telneting to the management interface port, or indirectly by using an OpenVPN GUI which itself connects to the management interface.

To enable the management interface on either an OpenVPN server or client, add this to the configuration file:

<strong>management localhost 7505</strong>

This tells OpenVPN to listen on TCP port 7505 for management interface clients (port 7505 is an arbitrary choice — you can use any free port).

Once OpenVPN is running, you can connect to the management interface using a telnet client. For example:

ai:~
# telnet localhost 7505 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. >INFO:OpenVPN Management Interface Version 1 -- type 'help' for more info help Management Interface for OpenVPN 2.0_rc14 i686-suse-linux [SSL] [LZO] [EPOLL] built on Feb 15 2005 Commands: echo [on|off] [N|all] : Like log, but only show messages in echo buffer. exit|quit : Close management session. help : Print this message. hold [on|off|release] : Set/show hold flag to on/off state, or release current hold and start tunnel. kill cn : Kill the client instance(s) having common name cn. kill IP:port : Kill the client instance connecting from IP:port. log [on|off] [N|all] : Turn on/off realtime log display + show last N lines or 'all' for entire history. mute [n] : Set log mute level to n, or show level if n is absent. net : (Windows only) Show network info and routing table. password type p : Enter password p for a queried OpenVPN password. signal s : Send signal s to daemon, s = SIGHUP|SIGTERM|SIGUSR1|SIGUSR2. state [on|off] [N|all] : Like log, but show state history. status [n] : Show current daemon status info using format #n. test n : Produce n lines of output for testing/debugging. username type u : Enter username u for a queried OpenVPN username. verb [n] : Set log verbosity level to n, or show if n is absent. version : Show current version number.
