Ping ne fonctionne plusFermé

Question

Bonjour,

j'apprends le fonctionnement d'un routeur, de dhcp et je fais quelque manipulation sous machine virtuelle ubuntu.
Je n'arrive plus a ping par exemple google.fr, j'obtiens ceci 

$ ping -c 1 google.fr
PING google.fr (216.58.211.99) 56(84) bytes of data.

--- google.fr ping statistics ---
1 packets transmitted, 0 received, 100% packet loss, time 0ms


j'arrive a ping mon routeur 
$ ping -c 1 192.168.132.2
PING 192.168.132.2 (192.168.132.2) 56(84) bytes of data.
64 bytes from 192.168.132.2: icmp_seq=1 ttl=128 time=0.125 ms

--- 192.168.132.2 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.125/0.125/0.125/0.000 ms

 

$ route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         192.168.132.2   0.0.0.0         UG    0      0        0 eth0
192.168.132.0   *               255.255.255.0   U     1      0        0 eth0


et j'ai désactiver le service network-manage

Salut,
pourquoi arrêter le network manager ?
C'est la porte ouverte à toutes les complications... surtout pour un bleu.
tu as mis un dns sur ta VM ?
