Hi folks - This set of patches change the Monitor Mode wireless interfaces to use radiotap both for monitoring and for packet injection. The monitoring side is done by a patch from Michael Wu. Tcpdump knows how to handle the result. For injecting packets, the you issue a packet using libpcap or a SOCK_PACKET socket down an interface to the wireless device that is in Monitor Mode. The packet has a normal radiotap header prepended to the IEEE80211 header. The radiotap header is variable length depending on what the user wants to specify, currently the transmit rate, power and antenna can be specified using normal radiotap semantics. Any other entries are skipped. A usermode app packetspammer is available from here http://penumbra.warmcat.com/_twk/tiki-index.php?page=packetspammer which allows easy injection of these packets from the commandline. At the moment it loops issuing packets at a variety of rates which can be seen from another machine's monitor mode interface on the same channel. There are instructions for build and using it on the page above. Currently it has been tested for both rx and tx using zd1211rw-mac80211. The patches should be based against wireless-dev. I also added a documentation file patch which explains how to use the injection functionality. -- - To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
