El servicio de red no se inicia / no se inicia al reiniciar.
Restarting networking (via systemctl): networking.serviceJob for networking.service failed because the control process exited with error code.
Todavía puedo acceder al servidor a través de la consola remota, pero nada más, ya que sin red, no hay salida ni entrada.
systemctl status networking.service dice:

Mi / etc / network / interfaces se ve así:
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet dhcp
¿Dónde puedo comenzar a depurar?
Gracias por cualquier pista! Saludos, K
# sudo ifup --verbose eth0

Usage: dhclient <snip>
Failed to bring up eth0.
sudo ifup --verbose eth0
para ver dónde van las cosas mal?
/var/log/syslog
. Podría intentar ejecutar el dhclient
comando manualmente por sí solo. Si no aparece un mensaje de error, no hay problema con dhclient
.
up
ejecutando, uno por uno, los scripts que se encuentran en/etc/network/if-up.d
. Uno de estos contiene undhclient
comando que falla. Así que haz algo comogrep -R dhclient /etc/network/if-up.d/*
y mira lo que obtienes.
