Configuring two networks with the same interface card

["Vadim Solonovich" <VSolon@agama.com>]

 Hi !

I want to set up my Debian to work with two ip addresses on different
networks with one ethernet card.
Asuming two different physical networks 192.168.0.0 and 192.168.1.0 :

# insmod ip_alias.o

# ifconfig eth0 192.168.0.1 netmask 255.255.255.0
# ifconfig eth0:0 192.168.1.1  netmask 255.255.255.0

# route add -net 192.168.0.0 dev eth0
# route add -net 192.168.1.0 dev eth0:0
# route add -host 192.168.0.1 dev eth0
# route add -host 192.168.1.1 dev eth0:0

Ping 192.168.0.10  is OK.

# ping 192.168.1.10
ping : sendto: Operation not permitted
ping : wrote: 192.168.1.10  64 chars, ret = -1

What's wrong ?
