When configured to authenticate with NTLMv1 (``ntlm`` keyword in
``--http-proxy``) OpenVPN will try NTLMv2 instead.
+``persist-key`` option has been enabled by default.
+ All the keys will be kept in memory across restart.

Change process priority after initialization (``n`` greater than 0 is
lower priority, ``n`` less than zero is higher priority).
---persist-key
- Don't re-read key files across :code:`SIGUSR1` or ``--ping-restart``.
-
- This option can be combined with ``--user`` to allow restarts
- triggered by the :code:`SIGUSR1` signal. Normally if you drop root
- privileges in OpenVPN, the daemon cannot be restarted since it will now
- be unable to re-read protected key files.
-
- This option solves the problem by persisting keys across :code:`SIGUSR1`
- resets, so they don't need to be re-read.
-
--providers providers
Load the list of (OpenSSL) providers. This is mainly useful for using an
external provider for key management like tpm2-openssl or to load the
Like with chroot, complications can result when scripts or restarts are
executed after the setcon operation, which is why you should really
- consider using the ``--persist-key`` and ``--persist-tun`` options.
+ consider using the ``--persist-tun`` option.
--status args
Write operational status to ``file`` every ``n`` seconds. ``n`` defaults
See the signals section below for more information on :code:`SIGUSR1`.
Note that the behavior of ``SIGUSR1`` can be modified by the
- ``--persist-tun``, ``--persist-key``, ``--persist-local-ip`` and
+ ``--persist-tun``, ``--persist-local-ip`` and
``--persist-remote-ip`` options.
Also note that ``--ping-exit`` and ``--ping-restart`` are mutually
``--route``, ``--route-gateway``, ``--route-delay``,
``--redirect-gateway``, ``--ip-win32``, ``--dhcp-option``, ``--dns``,
``--inactive``, ``--ping``, ``--ping-exit``, ``--ping-restart``,

Like :code:`SIGHUP``, except don't re-read configuration file, and
possibly don't close and reopen TUN/TAP device, re-read key files,

+ remote IP address/port based on ``--persist-tun``, ``--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.
--prng
Removed in OpenVPN 2.6. We now always use the PRNG of the SSL library.
+
+--persist-key
+ Ignored since OpenVPN 2.7. Keys are now always persisted across restarts.
