several ip on one eth0

Sushy · 07-26-2006, 08:49 AM

Hi!

I`m running Slackware 10.2 (Kernel 2.6.x)
I have one ip 1.1.1.1 on my eth0
I need to configure WAN iface with several ip
So I did:
# ifconfig eth0:0 1.1.1.2
# ifconfig eth0:1 1.1.1.3

Maybe there is some more operations i should perform?!

One network card can only have one IP address (unless you get into bridging and rather advanced stuff)

Are those your real IP-numbers??? For local networks there are the 10.*.*.* and 192.168.*.* ranges.
And as said... 1 ip per eth.

no sir
you can bind any amount of ip addresses to a single interface, that's possible even in windoze

You sintax is correct but I don't know for any other operations that you could do, besides of setting up your firewall as your liking

fyi eth0 = eth0:0

I would also include netmask:

ifconfig eth0:1 10.1.1.2. netmask 255.255.255.0

or whatever. This does work, done it many a time.
