|Hey guys, I have noticed that in my college and in my current work, when trying to log on to the wireless network with a windows machine, authentication is required in the form of logging in to a proxy via a web browser. However, when using a linux machine, authentication is not required. This is the same in both places.|
I am also aware that the browser (in my case firefox) sends information about the browser, operating system etc as part of a session so this could provide the proxy with the means of distinguishing the OSs. I then downloaded an addon for firefox - user agent switcher which configures firefox to send other information. I tried configuring it to send fake information stating that I was using a linux operating system. This, however did not fool the proxy and I was still required to authenticate.
Does anyone know if there are other mechanisms that the proxy can use to determine the operating system or perhaps I am not using the application correctly?
