[SOLVED] Creating another loopback interface

Hi,

I'm trying to follow a tutorial (in French) to bind specific applications to a VPN tunnel. It works fine except when I reach the part about creating a second loopback interface... It says:

Edit /etc/network/interfaces and add:

# The secondary loopback network interface
auto lo:1
        iface lo:1 inet static
        address 192.168.0.1
        netmask 255.255.255.255

My problem of course is that there is no /etc/network/interfaces file on my Arch setup.

I tried to use "ip link add" to create a loopback interface but it always returns an error message. Can't find any information about this anywhere. Can someone help?

# ifconfig lo:1 inet 192.168.0.1 netmask 255.255.255.255 up

I'd probably just stick it in a startup script if you want it plumbed permanently - this way you avoid it potentially being overwritten by system updates

Re: [SOLVED] Creating another loopback interface

Thanks! That does the trick and now the whole tutorial works for me .

I'll try to find the equivalent with the "ip" command instead of ifconfig.
