Hi everyone,

Can you explain me what snull is? I am developing network driver.

Thank you

Hi,

I guess you are reading the book about device drivers from O'Reilly.
As far as I remember snull is an example network driver that creates 2 interfaces. It works like loopback split in 2 devices.
Traffic send through one of the interfaces will be received at the other.

The book was written for kernel 2.4. I don't know if the code still works without modifications.

Hope it helps

I need to add ARP functionality to snull devices. How could I do? Thanks!
