Saya sedang mencoba memakai NMAP V. 2.3BETA9. Ada beberapa hasil dari NMAP yang
saya belum mengerti :
A Apa fungsi dari port seperti dibawah : 
   7       open        tcp       echo                    
   9       open        tcp       discard                 
   19      open        tcp       chargen 
   22      open        tcp       ssh                 
   57      open        tcp       priv-term 
   139     open        tcp       netbios-ssn              
   2001    open        tcp       dc                      
   6001    open        tcp       X11:1 

B. Apa yang dimaksud dengan hasil NMAP dibawah ?
-->TCP Sequence Prediction: Class=trivial time dependency
                         Difficulty=1 (Trivial joke)
      Remote operating system guess: Novell NetWare 3.12 or 386 TCP/IP
-->TCP Sequence Prediction: Class=random positive increments
                         Difficulty=2233755 (Good luck!)
-->TCP Sequence Prediction: Class=trivial time dependency
                         Difficulty=3 (Trivial joke)
      Remote operating system guess: Windows NT4 / Win95 / Win98
-->TCP Sequence Prediction: Class=random positive increments
                         Difficulty=20693 (Worthy challenge)
      Remote OS guesses: AS5200, Cisco 5260 or 5300 terminal server IOS
11.3.6(T1), Cisco IOS 11.3 - 12.0(2)
