Me conecté con éxito a un vpn desde mi computadora portátil con Windows y quiero ver qué hosts están en el grupo de trabajo llamado "Boston". Actualmente, el DNS del grupo de trabajo no está configurado para enumerar la mayoría de los nombres de las computadoras, así que solo estoy intentando las direcciones IP. Cuando escribo ipconfig
Veo lo siguiente (entre varias otras interfaces):
Ethernet adapter Ethernet 2:
Connection-specific DNS Suffix . : Boston.local
Link-local IPv6 Address . . . . . : fe80::2c21:fcc4:3359:e748%55
IPv4 Address. . . . . . . . . . . : 10.1.1.132
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . :
Acabo de arriesgarme y asumí que "Ethernet 2" implica la interfaz eth2, así que probé lo siguiente en Zenmap
nmap -sn -T4 -e eth2 10.1.1.0/24
Pero todo lo que obtengo son líneas como las siguientes:
Starting Nmap 7.12 ( https://nmap.org ) at 2018-09-20 15:12 Mountain Daylight Time
setup_target: failed to determine route to 10.1.1.0
setup_target: failed to determine route to 10.1.1.1
setup_target: failed to determine route to 10.1.1.2
setup_target: failed to determine route to 10.1.1.3
para todas las direcciones, incluida la mía. También obtengo los mismos resultados cuando intento 10.0.1.0/24 y 10.1.0.0/24 a pesar de que las tres subredes están en mis rutas
