Comments (Legacy) 
 Northcutt> Nmap and queso are the tip of the iceberg and not the most advanced
   ways to accomplish this.  To pursue making the world signature free
   is as much a vulnerability as having signatures, nay more.
 Frech> XF:decod-nmap(2053)
   XF:decod-queso(2048)
 Christey> Add "fingerprinting" to facilitate search.

 Baker> I think we can probably reject this as the corollary is that you can identify OS from a IP/TCP packet sent by a system, looking at various parts of the SYN packet.  Unless we believe that all systems should always use identical packet header/identical responses, in which case the protocol should not permit variation.
