Is it possible to start a windows openvpn client to make it connect using a predefined config (.ovpn) by supplying program arguments using command prompt. Or specifying the arguments in the shortcut when opening from windows shortcut etc.
Solved it as below:
from windows command prompt-
This is going to start the opn vpn gui client directly connecting to the connection specified in the config.
Mind you that if the
openvpn-gui.exe is already started above answers won't work. Pay attention to the :run section from a little batch file I made to automatically start openVPN connection when not at home:
rem This script is fired from Task Scheduler (using Custom Event filter) when I am NOT at home (not connected to home network) rem so check if my home NAS is already pingable, because maybe old/previous OpenVPN connection is still open rem if not then start OpenVPN connection rem if yes than do nothing ping -n 1 192.168.10.100 > testping.txt findstr /r /c:"Reply from \d*.\d*.\d*.\d*.* bytes=\d*.*time[<=]\d*.* TTL=\d*" testping.txt IF ERRORLEVEL 1 goto run rem do nothing because NAS is pingable goto finished :run rem be sure to kill previous (closed) openvpn process so reconnecting actually works! taskkill.exe /F /IM openvpn.exe taskkill.exe /F /IM openvpn-gui.exe timeout 1 start /b "" "C:\Program Files\OpenVPN\bin\openvpn-gui.exe" --connect nas_at_home.ovpn :finished
In additional to Flowerking's answer, you could specify the folder in which your ovpn file lives, perhaps to store private key data in user space. For that, use
openvpn-gui.exe --connect "client.ovpn" --config_dir "C:\Users\Foo\Documents\protected_crypto_data"
Here is a simple example, if you want to connect to more VPNs than one:
"C:\Program Files\OpenVPN\bin\openvpn-gui.exe" --connect vpn1.ovpn --connect vpn2.ovpn
It won't work, if the
openvpn-gui.exe is running.
Not sure if this was recently added but there's a "--command" option that can be used to send commands to a running gui instance.
So now you can do
openvpn-gui.exe --command connect config.ovpn
See the options for openvpn-gui.exe by going to the command line and running
You can improve @Jan 's answer by changing:
ping -n 1 192.168.10.100 > testping.txt findstr /r /c:"Reply from \d*.\d*.\d*.\d*.* bytes=\d*.*time[<=]\d*.* TTL=\d*" testping.txt
ping 192.168.10.100 -n 1 | findstr /r /c:"Reply from \d*.\d*.\d*.\d*.* bytes=\d*.*time[<=]\d*.* TTL=\d*" && goto :finished
This way you don't need to create a temporary file.
