Я не могу ifdown
интерфейс на Debian 6.0.5:
user@box:/etc/network$ sudo ifdown eth0 && sudo ifup eth0
ifdown: interface eth0 not configured
SIOCADDRT: File exists
Failed to bring up eth0.
user@box:/etc/network$ cat interfaces
auto lo
iface lo inet loopback
allow-hotplug eth0
allow-hotplug eth1
auto eth0
iface eth0 inet static
address 10.0.0.1
netmask 255.255.255.0
gateway 10.0.0.254
auto eth1
iface eth1 inet manual
По просьбе Марко:
user@box:/etc/network/$ cat /run/network/ifstate
lo=lo
eth1=eth1
/run/network/ifstate
содержит?
