Dummynet interfaces

The dummy modules in Linux allow you to have multiple "fake" network interfaces on your computer.

It's useful to test distributed programs locally.

Test if dummy is loaded :

lsmod | grep dummy

insmod dummy

Create a first dummy interface :

ifconfig dummy0 10.0.0.1

Create another one :

ifconfig dummy0:1 10.0.0.2

Destroy a dummy interface :

ifconfig dummyX:Y down
