Well, it sounds similar to a problem I encountered some time ago. Try like
this: the FromDevice "method" parameter, try setting it explicitly, e.g.
start with "method LINUX", the default is PCAP and not working on 3.x
kernels (the method which should be called to send a packet seems to be
compiled correctly, but it is skipped instead, since it is silently
substituted at configure time by a fake method which just returns - check
the configure logs file to accertain this). Ah, yes, if I remember
correctly,ToDevice inherits the method parameter from the corresponding
ToDevice, so you shouldn't need to declare the method there.
Hope this helps.
Cheers,
Giorgio
