hans-pcap

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. It is using ghc 7.8, thus the high dependencies. 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.
