OK, but what about eth0:0, the alias ? if I do something like:

# ip addr add dev eth0:0 192.168.101.1 etc etc

I get an error: 

cannot find device "eth0:0"

but I can create eth0:0 with ifconfig, but "ip link show" does not show me 
the interfaces, but with "ip route show" I see all of the eth0:x as only eth0.

# ip route show
200.51.164.128/29 dev eth0  proto kernel  scope link  src 200.51.164.131
192.168.101.0/24 dev eth0  proto kernel  scope link  src 192.168.101.1
192.168.102.0/24 dev eth0  proto kernel  scope link  src 192.168.102.1
127.0.0.0/8 dev lo  scope link
default via 200.51.164.134 dev eth0                                           
#

is this ok? I haev to create the "virtual" interfaces with ifconfig or do I 
have a way with ip?

thanks billy
