Dummy IP Interface
When I do:
ifconfig dummy
dummy: error fetching interface information: Device not found
Same with dummy0
I think I need to do an insmod dummy, but when I try:
insmod dummy
insmod: dummy: no module by that name found
And then I'm at the end of my linux knowledge. There doesnt appear to be a file like dummy in the filesystem. Where / how do I get this driver thing, and where do I put it? Is there a more permanent way of telling the kernel to load the driver on boot, or do I just stick the insmod command in the network startup?
Thanks.

# make the dev node, and make it world read/write-able, for non-root users (adjust to suit)
mkdir /dev/net/
mknod /dev/net/tun c 10 200

How much of this stuff is persistent?
(this does look like strange voodoo…)
