Log options
|
|
-----------
|
|
|
|
--echo parms
|
|
Echo ``parms`` to log output.
|
|
|
|
Designed to be used to send messages to a controlling application which
|
|
is receiving the OpenVPN log output.
|
|
|
|
--errors-to-stderr
|
|
Output errors to stderr instead of stdout unless log output is
|
|
redirected by one of the ``--log`` options.
|
|
|
|
--log file
|
|
Output logging messages to ``file``, including output to stdout/stderr
|
|
which is generated by called scripts. If ``file`` already exists it will
|
|
be truncated. This option takes effect immediately when it is parsed in
|
|
the command line and will supersede syslog output if ``--daemon``
|
|
is also specified. This option is persistent over the entire
|
|
course of an OpenVPN instantiation and will not be reset by
|
|
:code:`SIGHUP`, :code:`SIGUSR1`, or ``--ping-restart``.
|
|
|
|
Note that on Windows, when OpenVPN is started as a service, logging
|
|
occurs by default without the need to specify this option.
|
|
|
|
--log-append file
|
|
Append logging messages to ``file``. If ``file`` does not exist, it will
|
|
be created. This option behaves exactly like ``--log`` except that it
|
|
appends to rather than truncating the log file.
|
|
|
|
--machine-readable-output
|
|
Always write timestamps and message flags to log messages, even when
|
|
they otherwise would not be prefixed. In particular, this applies to log
|
|
messages sent to stdout.
|
|
|
|
--mute n
|
|
Log at most ``n`` consecutive messages in the same category. This is
|
|
useful to limit repetitive logging of similar message types.
|
|
|
|
--mute-replay-warnings
|
|
Silence the output of replay warnings, which are a common false alarm on
|
|
WiFi networks. This option preserves the security of the replay
|
|
protection code without the verbosity associated with warnings about
|
|
duplicate packets.
|
|
|
|
--suppress-timestamps
|
|
Avoid writing timestamps to log messages, even when they otherwise would
|
|
be prepended. In particular, this applies to log messages sent to
|
|
stdout.
|
|
|
|
--syslog progname
|
|
Direct log output to system logger, but do not become a daemon. See
|
|
``--daemon`` directive above for description of ``progname`` parameter.
|
|
|
|
--verb n
|
|
Set output verbosity to ``n`` (default :code:`1`). Each level shows all
|
|
info from the previous levels. Level :code:`3` is recommended if you want
|
|
a good summary of what's happening without being swamped by output.
|
|
|
|
:code:`0`
|
|
No output except fatal errors.
|
|
|
|
:code:`1` to :code:`4`
|
|
Normal usage range.
|
|
|
|
:code:`5`
|
|
Outputs :code:`R` and :code:`W` characters to the console for
|
|
each packet read and write, uppercase is used for TCP/UDP
|
|
packets and lowercase is used for TUN/TAP packets.
|
|
|
|
:code:`6` to :code:`11`
|
|
Debug info range (see :code:`errlevel.h` in the source code for
|
|
additional information on debug levels).
