Unable to change IP address for eth0 without restart in Ubuntu
- by Rodnower
I have Ubuntu 12.04.1 installed.
I tried to change the IP address of the interface eth0 in /etc/network/interfaces from 192.168.1.3 to 192.168.1.4
auto lo
iface lo inet loopback
pre-up iptables-restore < /etc/iptables.up.rules
auto eth0
iface eth0 inet static
address 192.168.1.4
gateway 192.168.1.1
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
sudo service networking status
When I issue:
sudo service networking restart
I get this response:
stop: Unknown instance:
networking stop/waiting
And IP remains 192.168.1.3:
eth0 Link encap:Ethernet HWaddr 00:1e:33:71:cd:a4
inet addr:192.168.1.3 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::21e:33ff:fe71:cda4/64 Scope:Link

Only after restart does the IP change.
Any ideas?
