But I'm curious by what you mean "it doesn't work"? Could you provide more details? Seems to work for me... well sorta. You always seem to loose the last few packets, but it's prolly due to packets getting lost mid-process when I CTRL-C to kill it. Could be a cross-platform issue (I tested under OS X), but that seems unlikely. > Do you have some ideas ? > > I also tried to use tcpbridge, but I'm not sureif I can use it on > promiscuous interface. tcpbridge puts the interfaces in promisc mode. > If someone can help me to choose the good solution, it will be really > nice.
