NOTA: si existe un paquete de rechazo ICMP al puerto especificado, se considera que la máquina está viva, es decir, "respondió con ICMP", así que no asuma que el puerto está abierto por el hecho de que Ping.pingecho le devuelva true.

net-ping
Fase común genérica para los siguientes ejemplos.

Ping UDP y TCP.

NOTA: en este caso el rechazo tanto a nivel TCP como ICMP no es indicativo de que la "máquina" esté viva, es decir, aquí el PING es específico al servicio/puerto que se está probando, no a la máquina. Note en el último caso el ping-tcp al puerto 80 donde si hay respuesta porque hay un servidor web funcionando allí.

Ping ICMP con net-ping.

Tenga presente que:

Ping "external", esta opción utiliza la utilidad "ping" de su sistema operativo.

Por cierto, net-ping no está empaquetado en Fedora, ello es una buena oportunidad para que comiences tu primer proyecto de empaquetamiento de rubygems en Fedora, contáctame y suscribe en el grupo de desarrollo latinoamericano RPMDev.
