Construyendo un arma específica contra la dictadura

Hasta la fecha todo ha sido ir probando herramientas y comandos de forma manual, en base al análisis de sus resultados nos hemos hecho una idea más o menos acertada de la red del “país”. El siguiente script automatiza parte del trabajo manual y ahorra tiempo, todos los servicios susceptibles de ser atacados los tienen la mayoría del tiempo apagados, y casi todos están instalados en hosts con servicios web, por lo que si el servicio web no funciona los servicios que pretendemos analizar estarán también apagados, por eso no los escaneamos. El script lo podemos ejecutar manualmente o programarlo en crontab para que lo ejecute cron (servicio de crontab) a determinadas horas o cada x minutos como una tarea.

Ejecutamos el script y vemos que funciona perfectamente
