+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.
