Hi!

I have looked for this in very many forums but I didn't find something.

I have a problem to add virtual interface on fedora 8.
I've done installation of fedora 8 as server.
I have ip from dhcp server and after NAT.
So my ip address is 192.168.0.22.
Subnet mask 255.255.255.0 and default gateway is 192.168.0.254.
I need to create two virtual interfaces eth0:1 and eth0:2.
I have done the following things:

ifconfig eth0:1 192.168.0.101 netmask 255.255.255.0 up
ifconfig eth0:2 192.168.0.102 netmask 255.255.255.0 up

After " ifconfig -a "

I saw that I have new interfaces but when I'll try to add them to the kernel IP routing table I have some strange problem.

route add -net 192.168.0.0 netmask 255.255.255.0

Error : SIOCADDRT invalid argument

So I'd like to see after "route"
that I have in column Iface eth0:1 and etho:2
now I see only eth0.

Thank you very much for help.

You have successfully added the virtual interfaces, you are having trouble adding the network to the routing table.

Possibly missing out some of these steps caused some confusion.


route command error messages[pdf]

SIOCADDRT is an error message ADDing a RouTe.
"invalid argument" normally comes from missing something out. The line:
looks fine though. Is there anything else to the error message?
