static send_function(x, inter=0, loop=0, iface=None, iface_hint=None, count=None, verbose=None, realtime=None, return_packets=False, socket=None, *args, **kargs)¶

Send packets at layer 2

Parameters

x – the packets
inter – time (in s) between two packets (default 0)
loop – send packet indefinetly (default 0)
count – number of packets to send (default None=1)
verbose – verbose mode (default None=conf.verbose)
realtime – check that a packet was sent before sending the next one
return_packets – return the sent packets
socket – the socket to use (default is conf.L3socket(kargs))
iface – the interface to send the packets on
monitor – (not on linux) send in monitor mode

Returns

None
