Client reconnects before client-disconnect script is run.

artheus

Hi everyone,

I've been googling this and haven't found any solution to this problem. So I'm hoping for some help here.

My problem is:
I am setting up an automated authentication system based on the users common_name and ip-address in the system.
Therefore I run some scripts like client-connect and client-disconnect to be able to track when users log in and out, and what their IP-adresses are.
I have set up the clients to Ping every 10th second and the Server is set to ping-exit after 20 seconds.

So when a client disconnects now, the client-disconnect script will be executed after 20 seconds and tell the database that the user has now disconnected.

But! If the client just disconnects and directly connects again, the client-connect script will run before the client-disconnect, and therefore set the user as disconnected.

I know that there are some ways for me to fix this by coding, but I would rather know if there is a way to set up openvpn so it better suits my problem and solution.

Is there another way to setup the server and the client, more "event driven" so that they don't poll every 20 seconds?
Or does anyone here have a better solution for this?

Thanks!

Actually, there is not need for OpenVPN to implement what you need. Think of this situation: clients authentiate using same common name or secret file (there is needs for this type). So, some user didnt disconnect and there is no need for client-disconnect script to run. Another user connects. If OpenVPN would wait for a client-disconnect script, other users could not connect.

Your only option is to tweak times and adjust your scripts.

Great Answer. Thanks.

I will try solving this by script.
