There is one pptp server and I use radius server for authentication. Sometimes the vpn client is off line with unknow reason , so the radius can not clear the session for client.
I want to run one process with radius client to monitor the client, if the client has no heartbeat, the process will send logout request to radius server for client.
So i want to know what is the logout request message in radius client?
You've tagged your question with several languages.
Assuming you would like to do this in Python, you can use Pyrad and use one of the method from pyrad.packet.
