Linux Mint 12 : configure IP aliases

Configure IP alias temporarily

ifconfig eth1:0 1.1.1.10 netmask 255.255.255.0 up # LANG=C ifconfig eth1:0 | grep "inet addr"          inet addr:1.1.1.10  Bcast:1.1.1.255  Mask:255.255.255.0

cerase IP alias

# ifconfig eth1:0 down

Configure IP alias permanently

edit /etc/network/interfaces file

auto eth1 iface eth1 inet static        address 192.168.200.150        netmask 255.255.255.0        up ifconfig eth1 add 1.1.1.10 netmask 255.255.255.0

# /etc/init.d/networking restart

# LANG=C ifconfig eth1:0 | grep "inet addr"          inet addr:1.1.1.10  Bcast:133.199.130.0  Mask:255.255.255.0

In my environment , I can’t assign IP aliases when editing interfaces file as below

auto eth1 iface eth1 inet static        address 192.168.200.150        netmask 255.255.255.0 auto eth1:0 iface eth1:0 inet static        address 1.0.0.10        netmask 255.255.255.0

# /etc/init.d/networking restart

can’t assign the IP alias…

# LANG=C ifconfig eth1:0 | grep "inet addr"

I don’t know why :(
