nmap -O y xprobe2

[cyberboom99]

hola, buenos dias, tengo una duda he hecho un
nmap -O 173.XXX.XXX.XX (es de un site)

y me resulta:

Running (JUST GUESSING) : Linux 2.6.X|2.4.X (90%), Avaya Linux 2.6.X (89%), F5 Networks embedded (89%), IPCop Linux 2.4.X (89%), USRobotics embedded (87%), FreeBSD 6.X (85%), Check Point Linux 2.4.X (85%), Cisco embedded (85%)
Aggressive OS guesses: Linux 2.6.24 (90%), Avaya Communication Manager (Linux 2.6.11) (89%), F5 BIG-IP load balancer (89%), IPCop firewall 1.4.10 - 1.4.21 (Linux 2.4.31 - 2.4.36) (89%), Linux 2.6.24 (Gentoo) (89%), OpenWrt (Linux 2.4.32) (88%), USRobotics USR5450 WAP (87%), FreeBSD 6.2-RELEASE (85%), FreeBSD 6.3-RELEASE (85%), Check Point firewall (Linux 2.4.21) (85%)


y al hacer un xprobe2 a la misma ip:

Running OS: "Apple Mac OS X 10.3.7" (Guess probability: 100%)

Los resultados de NMap suelen ser bastante fiables, sin embargo el sistema operativo puede "adivinarse" inspeccionando los puertos abiertos y los servicios prestados, algunos de ellos te indican de antemano que tipo de sistema puede ser.
