Hi all,
I have a hotspot system. When a user connects, I create a file with the mac-address from which he accesses it. This because I set a limit of devices per user. But I have the following problem. For example, if a user connects and has reached the maximum limit of mac-address, I would like that the user receive an error message. Specifically, I would like that, when the user logs in, I check the number of mec-address in his file. If it has reached the maximum number, the user must receive an error. Could you tell me how and if it is possible to do this?
Thank you
