How to limit how many users can be simultaneously connected

[linkeong]

Hi, I would like to ask if anyone out there can help me with this problem

Currently on my openvpn, I am running 1 key per client but the problem is the clients can share the keys with another computer and still be able to connect to the vpn server.

If 2 are connected with the same key, both are able to use the vpn. I do not have duplicate-cn enabled in my config and my config is pretty much the standard ones.

Lol! Well, then--enable duplicate-cn on the server and your problem will be solved. If one of your end-users calls and complains that they cannot connect and you see that their certificate is currently in use by Some Else, scold your user, revoke the old cert and create a new one for him.

Problem solved!
