You can run:

Code:

ifconfig eth0:0 x.x.x.x netmask y.y.y.y up

It's true. You will lose the settings when you reboot. But you can add the ifconfig command to your init srcipts, e.g. to /etc/rc.d/rc.local, so there will be no need to re-enter it:

Code:

/sbin/ifconfig  eth0:0 x.x.x.x netmask y.y.y.y up

Much cleaner is adding these lines to /etc/rc.d/rc.inet1.conf where the network configuration for your eth0 is done too:

Code:

# Config information for eth0:0
IFNAME[1]="eth0:0"
IPADDR[1]="XXX.XXX.XXX.XXX"
NETMASK[1]="YYY.YYY.YYY.YYY"
USE_DHCP[1]=""
DHCP_HOSTNAME[1]=""

After which you can run

Code:

/etc/rc.d/rc.inet1 eth0:0_start

to start the interface. And it will automatically be configured and started on boot.

Change the XXX.XXX.XXX.XXX and YYY.YYY.YYY.YYY to your TCPIP parameters.
