I have a server located remotely running CentOS 5.x. I need to have two IP's on the same interface. So I have this: /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 BOOTPROTO=none BROADCAST=69.x.x.199 HWADDR=00:x:x:x:c6:10 IPADDR=69.x.x.194 NETMASK=255.255.255.248 NETWORK=69.x.x.192 ONBOOT=yes GATEWAY=69.x.x.193 TYPE=Ethernet So I added this: /etc/sysconfig/network-scripts/ifcfg-eth0:0 DEVICE=eth0 BOOTPROTO=none BROADCAST=69.x.x.199 HWADDR=00:x:x:x:c6:10 IPADDR=69.x.x.195 NETMASK=255.255.255.248 NETWORK=69.x.x.192 ONBOOT=yes GATEWAY=69.x.x.193 TYPE=Ethernet Now the only IP that works is the second one. What am I doing wrong? Thanks. Matt

What am I doing wrong?In ifcfg-eth0:0, DEVICE line should look like this: DEVICE=eth0:0

What am I doing wrong?You want DEVICE=eth0:1 (or what ever your interface alias is) --Tim

Then set your ifcfg-eth0:2 Bo

You need to have DEVICE=eth0:0 in the second script, otherwise you just overwrite the previously assigned IP address.
