How to track a PC on a unix server that disguises its user-agent as mobile devices?

Question

Network administration

the question is not about layout. this is for incoming traffic analytics. by what parameters can you understand that this is a PC, and not a physical mobile device?

Answer 1

By digital "cast" can be distinguished. To begin with, consider everyone as a PC, but those who subsequently provided a correct cast - as mobile devices.
"user-agent" is just a string - you can fake it however you like. And the cast is the result of the work of JS on the client side - it’s already harder to fake here.

Answer 2

Mobile is when there is no onhover :)
Mobile(useragent)+onhover = THIS IS IT!!!
