 Airtun-ng also has repeater and tcpreplay-type functionality.  There is a repeater function which allows you to replay all traffic sniffed through a wireless device (interface specified by -i at0) and optionally filter the traffic by a bssid together with a network mask and replay the remaining traffic.  While doing this, you can still use the tun interface while repeating.  As well, a pcap file read feature allows you to replay stored pcap-format packet captures just the way you captured them in the first place.  This is essentially tcpreplay functionality for wifi. Airtun-ng also has repeater and tcpreplay-type functionality.  There is a repeater function which allows you to replay all traffic sniffed through a wireless device (interface specified by -i at0) and optionally filter the traffic by a bssid together with a network mask and replay the remaining traffic.  While doing this, you can still use the tun interface while repeating.  As well, a pcap file read feature allows you to replay stored pcap-format packet captures just the way you captured them in the first place.  This is essentially tcpreplay functionality for wifi.
