SIGNALS ======= :code:`SIGHUP` Cause OpenVPN to close all TUN/TAP and network connections, restart, re-read the configuration file (if any), and reopen TUN/TAP and network connections. :code:`SIGUSR1` Like :code:`SIGHUP``, except don't re-read configuration file, and possibly don't close and reopen TUN/TAP device, re-read key files, preserve local IP address/port, or preserve most recently authenticated remote IP address/port based on ``--persist-tun``, ``--persist-key``, ``--persist-local-ip`` and ``--persist-remote-ip`` options respectively (see above). This signal may also be internally generated by a timeout condition, governed by the ``--ping-restart`` option. This signal, when combined with ``--persist-remote-ip``, may be sent when the underlying parameters of the host's network interface change such as when the host is a DHCP client and is assigned a new IP address. See ``--ipchange`` for more information. :code:`SIGUSR2` Causes OpenVPN to display its current statistics (to the syslog file if ``--daemon`` is used, or stdout otherwise). :code:`SIGINT`, :code:`SIGTERM` Causes OpenVPN to exit gracefully.
