[Full-Disclosure] [tool] the new p0f 2.0.1 is now out

[Peter van den Heuvel]

Hi,

UDP port 53 gets queried on several of the firewalls that I maintain 
(and that do not provide any domain name services) from netblocks that 
are owned by microsoft and realmedia (mostly). None of the machines 
behind these firewalls are allowed any external DNS directly. The 
queries are rather massive (thousands per week).

Searches on google did not turn up anything and I don't remember seeing 
anything on the lists either (though I migh have prematurely deleted 
something relevant because of the noise ;^)

It does not realy hurt us, but I'm still quite curious what this 
actually is. Anybody got a pointer?

Peter
