Network ethernet device for HaNS hans-2.4, which can tap into a real ethernet interface, all using pcap library and preform raw packet reads & writes. This is a very naive implementation, however not much more can be squeezed from PCAP. Top run requires: root - all because we need to use PCAP
example use:
import Hans.NetworkStack
import Hans.Device.Pcap
main :: IO ()
main = do
ns <- newNetworkStack
-- MAC we want to have; make it unique
let mac = Mac 1 2 3 4 5 6
-- device we attach to
dev <- pcapOpen "eth0"
addDevice ns mac (pcapSend dev) (pcapReceiveLoop dev)
deviceUp ns mac
And we can continue using HaNS as normal. See example/gal.hs for a working example.
It requires libpcap-dev (as it is required by pcap) to run, So on Debian (or simmilar)_
sudo apt-get install libpcap-dev
