Multiple IPs

[Thomas Kaiser]

I do it like this in /etc/network/interfaces :

auto eth0:0	# to start at boot
iface eth0:0 inet static
     address 192.168.0.1
     netmask 255.255.255.0

auto eth0:1	# to start at boot
iface eth0:0 inet static
     address 192.168.1.1
     netmask 255.255.255.0

auto eth0:3	# to start at boot
iface eth0:0 inet static
     address 192.168.3.1
     netmask 255.255.255.0

Mybe the next example does also work, but I never tried:

auto eth0:3	# to start at boot
iface eth0:4 inet dhcp

Regards, Thomas
