Machine dependent web application login

Is there a way to limit the login to a web application based on client machine name or id. The requirement is a certain userid login should be done only from pre-determined or preset systems.

Hope this covers the queries mentioned.

I am not sure if IP address of the machine can be used as much effective as the machine name or macid may server the purpose. Client OS can be windows or mac. Its a public facing site but a certain group of users should login from certain machines only. The site is php, mysql and hosted on apache and l开发者_如何学编程inux.

Generally speaking, a web browser will only send basic HTTP headers along for the ride, in addition to a known IP address.

Assuming you even could get this information from the client system via javascript, it would not be trustable, (eg, a client could fake it).

Perhaps you can expand your question a bit?
