This one has been cracking my head for quite a bit and I can't seem to find a decent answer for it, hoping you guys can shed some light to it...
Code:
# Loopback interface:
auto lo
iface lo inet loopback
# Ethernet 0 interface:
auto eth0
iface eth0 inet static
address 10.10.20.100
netmask 255.255.255.0
network 10.10.20.0
broadcast 10.10.20.255
gateway 10.10.20.1
dns-nameservers 10.10.20.1 8.8.8.8
hwaddress ether XXXXXXXX
dns-search defaultdomain
# Ethernet 1 interface:
auto eth1
iface eth1 inet static
address 10.10.20.125
netmask 255.255.255.0
network 10.10.20.0
broadcast 10.10.20.255
gateway 10.10.20.1
dns-nameservers 10.10.20.1 8.8.8.8
hwaddress ether XXXXXX
dns-search defaultdomain
When i reboot the machine i'm able to have the correct ip addresses
Code:
eth0 Link encap:Ethernet HWaddr XXXXXXXXXXXXXX
inet addr:10.10.20.100 Bcast:10.10.20.255 Mask:255.255.255.0

However when I change anything on the networking file i can only get it to apply by doing a machine reboot at the moment (plain stupid workaround)
- service networking restart doesn't seem to do anything
- ifdown eth0 && ifup eth0 gives ifdown: interface eth0 not configured RTNETLINK answers: File exists Failed to bring up eth0.
- ip link set eth0 down && ip link set eth0 up doesn't seem to do anything
How on earth do I make the network pickup the changes, seriously this is getting on my nerves...
I'm using ubuntu 12.04 virtualized using KVM inside an Ubuntu 12.04 Dom0
