How to detect OS with Snort?

[Borja Luaces <borja.luaces () gmail com>]

Good afternoon,

First of all I have to say that I am new to Snort.

I am trying to create an alert rule to detect the OS but everytime I try it
it seems not to work.

The rule looks like the following one:

alert tcp any any -> any any (content:"Windows NT";msg:"Microsoft OS
detected";)

Any help?

Thanks for your time
