How to setup network interface to have eth0 as dhcp and eth0:1 as static ip?

Question

Im trying to configure my network to have both a static IP and a DHCP IP

the system in question is ubuntu server 11.10 with only additional software being the LAMP bundle (web server) and OpenSSH.

I tried this configuration bellow with mixed success. sometimes i only get the DHCP IP and not the static one, and other times i get the static IP and not the DCHP one.

Am I doing something wrong with the configuration?

---

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

auto eth0:1
iface eth0:1 inet static
address 192.168.0.2
netmask 255.255.255.0
gateway 192.168.0.1
broadcast 192.168.0.255

Answer 1

Try to remove the auto eth0:1 and add it together with the first one on this way:

auto eth0 eth0:1
iface eth0 inet dhcp

iface eth0:1 inet static
address 192.168.0.2
netmask 255.255.255.0
gateway 192.168.0.1
broadcast 192.168.0.255

I had Issues when specifying two times auto for the same physical iface.
