tunnel device

Hi,

I am developping a routing protocol for bluetooth. I want to add a network
device interface to my bluetooth software, so that ie ssh can talk over
bluetooth to other computers.

Does anybody know where to find information about tunnel devices or how to
create a network interface?

An application that does what I am searching for would be a great help too
because I could copy sourcecode.

regards,
Benjamin

PS: I want to receive plain ip-packages in my routing-application from the
tunnel device.

regards,
Benjamin

Have a look at the tun/tap device driver.

The tun driver creates a character device and a network
device for IP frames and connects the devices together.
The IP packets coming into the network end can be read
out of the character device and vice versa.

The tap driver handles Ethernet frames in the same way.

It is not clear to me just what you have in mind, but...

Hi Tauno,

thanks, thats what I am looking for.

Hi,

I am using the kernel supported tun function now. But when I call
fd=tun_open(char *dev) I dont get a valid fd handle back. I think the
problem is dev, I dont know how I have to set it. I tried to set it to
"tun0" but it didnt work.

regards,
Ben

Hi,

I found my problem, I used the old tun_open function.
