Two IP's on one NIC

Hi,

I want to add a virtual eth0:1 to my first NIC.
How can I do this?

I copy the eth0-file to eth0:0 and change the IP adresses in it.
(the files are in /etc/sysconfig/network)

and if I make a "ifup eth0:0", linux said:

eth0:0
ERROR: Interface eth0:0 is not available

that means ifup finds the configfile, but it doesn find the interface,....
What can I do?



thanks in advance

Markus

what distribution?

check that you have a
DEVICE=eth0:0
in your 'config file'


However, you can always 'ifconfig' it.

I added "DEVICE=eth0:0" in my ifcfg-eth0:0
and the same error appears

The new way? Start the machine in GUI mode go throught he system
configuration menus and do it from there. Change the settings and reboot
the machine :-)

The scripts that actually start up an interface and likes are built around
ifconfig.
