scapy发送无线beacon帧

使用scapy发送无线beacon帧，伪造AP代码示例：
代码来源：4armd博客

from scapy.all import Dot11,Dot11Beacon,Dot11Elt,RadioTap,sendp,hexdump

netSSID = 'testSSID' #Network name here
iface = 'wlan0'   #Interface name here

dot11 = Dot11(type=0, subtype=8, addr1='ff:ff:ff:ff:ff:ff', 
addr2='22:22:22:22:22:22', addr3='33:33:33:33:33:33')
beacon = Dot11Beacon(cap='ESS+privacy')
essid = Dot11Elt(ID='SSID',info=netSSID, len=len(netSSID))

rsn = Dot11Elt(ID='RSNinfo', info=(

frame = RadioTap()/dot11/beacon/essid/rsn
frame.show()
print("\nHexDump of frame:")
hexdump(frame)
raw_input("\nPress enter to start\n")
sendp(frame, iface=iface, inter=0.100, loop=1)
