OpenVPN management interface on windows machine with OpenVPN Server

[Kaos981]

Hi guys

I've tried to search for a solution on the forum but unfortunately i had no luck.
I have this problem: i've tried to configure the server.conf file with the string

Code: Select all

management localhost 7505

and restarted the openvpn server instance, but i can't connect to the management interface via telnet on the same machine, windows says that can't connect to the ip address 127.0.0.1 7505 and doesn't exist.
Can someone please help me to understand how to fix this?
Best regards
Marco

Any other suggestion? Thanks in advance

MANAGEMENT: Client connected from [AF_INET]127.0.0.1:25340

This is the connection from openvpn_gui.exe ..
You cannot use the management port for telnet while using the GUI.

[Kaos981]

Ah!!! Thanks, you got it.
So there are other possibilities to kill some clients from the GUI? Or how can i start OpenVPN without GUI.
Many thanks for your precious help.

Hi again, found this on the documentation, is this the right way to start the server without the GUI?

Configuring OpenVPN to run automatically on system startup:
Windows

The Windows installer will set up a Service Wrapper, but leave it turned off by default. To activate it, go to Control Panel / Administrative Tools / Services, select the OpenVPN service, right-click on properties, and set the Startup Type to Automatic. This will configure the service for automatic start on the next reboot.

When started, the OpenVPN Service Wrapper will scan the \Program Files\OpenVPN\config folder for .ovpn configuration files, starting a separate OpenVPN process on each file.

Marco

[TinCanTech]

That is one way ..

Another is to open an administrator cmd and type the start command:

Code: Select all

C:\Program Files\Openvpn\config> ..\bin\openvpn config-file-name.ovpn
