According to the Aliasing Mini-Howto I set up two virtual addresses. The addresses are working but ifconfig swows only the one address of eth0 and not the other virtual ones for eth0:0 and eth0:1.
The route command shows me that there is a host route to each IP connected with the virtual interfaces (I did a route add -host <IP> dev <virtual>). Another problem occurs if I try to set the network route. If I issue route add -net 127.0.0.0 the answer is SIOCADDRT: Invalid argument route add 127.0.0.0 dev lo works but results only in a host route. The same happens if I set the network route route add -net 192.168.10.0 dev eth0 I can set the default route to a gateway on the network and if I look at the routes with "route -n" there is also a route to the network. Currently I am not physically connected. I am going to connect but want to prepare most in advance. I am using a RealTek PCI ethernet card (rtl8139). --Werner
