I need to be able to recognize the various PCs connecting to the server. The reason for this request is this: in an application that I am developing in PHP for a company intranet, I was specifically asked not to ask employees to log in. Absurd, but unfortunately true.
So, I thought the only way to recognize the connecting machine was to recognize the same machine on the network. The IP number is dynamically assigned, so it is useless to resort to it, so I just have to read the computer name. Except that I work in PHP and I don't know how to do it, I think it is practically impossible to script unless I use an external command, which I would like to avoid if possible for security reasons. So the question is is there a sure way to achieve this or am I a utopian?
