Vamos haber varias herramientas que nos permiten conocer los equipos alcanzables de nuestra red loca.
Nmap
Nmap es un programa de código abierto que sirve para efectuar rastreo de puertos escrito originalmente por Gordon Lyon (más conocido por su alias Fyodor Vaskovich). Se usa para evaluar la seguridad de sistemas informáticos, así como para descubrir servicios o servidores en una red informática.
rokitoh@red-orbita:~$ nmap -sP 192.168.1.1/24
Starting Nmap 5.00 ( http://nmap.org ) at 2011-08-30 14:03 CEST
Host 192.168.1.1 is up (0.00058s latency).
Host 192.168.1.102 is up (0.00025s latency).
Nmap done: 256 IP addresses (2 hosts up) scanned in 2.54 seconds

fping
Instalación para debina o derivados.
rokitoh@red-orbita:~$ apt-get install fping
Fping es una herramienta que te permite enumerar una red en poco tiempo, y especificar en un rango de red determinadocuales son las ip que están activasdentro de ese rango.
rokitoh@red-orbita:~$ fping -g 192.168.1.1/24 2> /dev/null | grep alive
192.168.1.1 is alive
192.168.1.102 is alive
ip neig
Herramienta de configuración del protocolo ip. Con ella podemos ver y modificar rutas.
rokitoh@red-orbita:~$ ip neig
