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
