Installation Instructions for OpenVPN GUI for Windows
#####################################################
OpenVPN-GUI has been bundled with OpenVPN installers for a long time, so there
is rarely a need to install it separately. Bleeding-edge
versions of OpenVPN-GUI are available in `OpenVPN snapshot
installers <http://build.openvpn.net/downloads/snapshots/>`_ based on Git master
branch. OpenVPN-GUI gets installed by default in all OpenVPN installers.
Installation using the official OpenVPN installers
**************************************************
* Download an `OpenVPN installer <https://openvpn.net/index.php/open-source.html>`_
* If you have a previous version of OpenVPN GUI running, shut it down.
Make sure it's closed by ALL logged on users.
* Run the OpenVPN installer
Manual installation of OpenVPN GUI
**********************************
* `Download <https://openvpn.net/index.php/download/community-downloads.html>`_
and install OpenVPN
* Download OpenVPN GUI of your choice and save it in OpenVPN's bin folder.
Default is *C:\\Program Files\\OpenVPN\\bin\\*. You must put it in this folder
because OpenVPN GUI depends on the OpenSSL DLLs installed in this folder by
OpenVPN.
Configuring OpenVPN GUI to start on Windows logon
*************************************************
OpenVPN GUI can be configured to start automatically on logon to Windows from
its setting menu. This is default behavior for all users if OpenVPN GUI was
installed by an OpenVPN 2.4 installer using default installer options.
Adding an OpenVPN configuration file
************************************
To launch a VPN connections using OpenVPN GUI you need to add an OpenVPN
configuration file with .ovpn suffix. Any text editor (e.g. notepad.exe) can be
used to create a OpenVPN configuration files. Note that *log* and *log-append*
options are ignored as OpenVPN GUI redirects the normal output to a log file
itself. There are sample config files in the *sample-config* folder. Please
refer to the `OpenVPN project homepage <https://openvpn.net>`_ for more
information regarding creating the configuration file.
Once the configuration file is ready, you need to let OpenVPN GUI know about it.
There are three ways to do this:
* Place the file into the system-wide location, usually
*C:\\Program Files\\OpenVPN\\config\\*, or any of its immediate
subdirectories. This VPN connection will be visible for all users of the
system.
* Place the file into *C:\\Users\\username\\OpenVPN\\config\\*, or any of its
immediate subdirectories. The configuration file is only visible for the
user in question. If the user is not a member of the built-in "Administrators"
group or "OpenVPN Administrators" group and tries to launch such a connection,
OpenVPN GUI pops up a UAC, offering to create the latter group (if missing)
and to add the user to it. This will only work if admin-level credentials are
available.
* Use the "Import file" function in OpenVPN GUI itself
Using OpenVPN GUI
#################
When OpenVPN GUI is started your OpenVPN config folders
(*C:\\Users\\username\\OpenVPN\\config* and
*C:\\Program Files\\OpenVPN\\config*) will be scanned for .ovpn files and the
OpenVPN GUI icon will appear in the system tray. Each OpenVPN configuration
file shows up as a separate menu item in the OpenVPN GUI tray, allowing you to
selectively connect to and disconnect to your VPNs. The config dir will be
re-scanned for new config files every time you open the OpenVPN GUI menu by
right-clicking the icon.
When you choose to connect to a site OpenVPN GUI will launch openvpn with
the specified config file. If you use a passphrase protected key you will be
prompted for the passphrase.
If you want OpenVPN GUI to start a connection automatically when it's started,
you can use the --connect cmd-line option. The extension of the config file
may be optionally included. Example::
openvpn-gui --connect office.ovpn
OR
openvpn-gui --connect office

channels <https://community.openvpn.net/openvpn/wiki/GettingHelp>`_.
Running OpenVPN GUI as a Non-Admin user
***************************************
OpenVPN 2.3.x and earlier bundle an OpenVPN GUI version (< 11) which has to be
run as admin for two reasons
* OpenVPN GUI registry keys are stored in system-wide location
under HKEY_LOCAL_MACHINE, and they are generated when OpenVPN GUI was
launched the first time
* OpenVPN itself requires admin-level privileges to modify network settings
OpenVPN GUI 11 and later can make full use of the Interactive Service
functionality in recent versions of OpenVPN. This changes a number of
things:
* OpenVPN GUI can store its settings in user-specific part of the registry under
HKEY_CURRENT_USER
* OpenVPN is able to delegate certain privileged operations, such as adding
routes, to the Interactive service, removing the need to run OpenVPN with
admin privileges. Note that for this to work the *OpenVPNServiceInteractive*
system service has to be enabled and running.
Run Connect/Disconnect/Preconnect Scripts
*****************************************
There are three different scripts that OpenVPN GUI can execute to help
with different tasks like mapping network drives.
Preconnect If a file named "xxx_pre.bat" exist in the config folder
where xxx is the same as your OpenVPN config file name,
this will be executed BEFORE the OpenVPN tunnel is established.
Connect If a file named "xxx_up.bat" exist in the config folder
where xxx is the same as your OpenVPN config file name,
this will be executed AFTER the OpenVPN tunnel is established.
Disconnect If a file named "xxx_down.bat" exist in the config folder
where xxx is the same as your OpenVPN config file name,
this will be executed BEFORE the OpenVPN tunnel is closed.
The outputs of these scripts are redirected to "xxx_pre.log",
"xxx_up.log" and "xxx_down.log" respectively. These log
files are created in the ``log_dir`` and over-written during
each evocation.
Send Commands to a Running Instance of OpenVPN GUI
**************************************************
When an instance of the GUI is running, certain commands may be sent to
it using the command line interface using the following syntax::
openvpn-gui.exe --command *cmd* [*args*]
Currently supported *cmds* are
connect ``config-name``
Connect the configuration named *config-name* (excluding the
extension .ovpn). If already connected, show the status window.
disconnect ``config-name``
Disconnect the configuration named *config-name* if connected.
reconnect ``config-name``
Disconnect and then reconnect the configuration named *config-name*
if connected.
disconnect\_all
Disconnect all active connections.
silent\_connection 0 \| 1
Set the silent connection flag on (1) or off (0)
exit
Disconnect all active connections and terminate the GUI process
rescan
Rescan the config folders for changes
import ``path``
Import the config file pointed to by ``path``.
If no running instance of the GUI is found, these commands do nothing
except for *--command connect config-name* which gets interpreted
as *--connect config-name*
Registry Values affecting the OpenVPN GUI operation
***************************************************
Parameters taken from the global registry values in
*HKEY_LOCAL_MACHINE\\SOFTWARE\\OpenVPN\\* key
(Default)
The installation directory of openvpn (e.g., *C:\\Program Files\\OpenVPN*).
This value must be present.

User Preferences
****************
All other OpenVPN GUI registry values are located below the
*HKEY_CURRENT_USER\\SOFTWARE\\OpenVPN-GUI\\* key. In a fresh
installation none of these values are present and are not
required for the operation of the program. These keys are only
used for persisting user's preferences, and the key names
and their values are subject to change.
The user is not expected to edit any of these values directly.
Instead, edit all preferences using the settings menu.
