+QueSO homepage -- http://www.apostols.org/projectz/queso/
+
+How we can determine the remote OS using simple tcp packets?  Well,
+it's easy, they're packets that don't make any sense, so the RFCs
+don't clearly state what to answer in these kind of situations.
+Facing this ambiguous, each TCP/IP stack takes a different approach
+to the problem, and this way, we get a different response.  In some
+cases (like Linux, to name one) some programming mistakes make the OS
+detectable.
+
+QueSO sends:
+
+        0 SYN           * THIS IS VALID, used to verify LISTEN
+        1 SYN+ACK       
+        2 FIN
+        3 FIN+ACK
+        4 SYN+FIN
+        5 PSH
+        6 SYN+XXX+YYY   * XXX & YYY are unused TCP flags
+
+All packets have a random seq_num and a 0x0 ack_num.
