I am writing a python script that creates UDP packets at layer 2 with Scapy.

However, I continually get a "TypeError" when including UDP() options/attributes in the definition of the packet.

Code:

Return_Data = sendp( Ether(dst="ff:ff:ff:ff:ff:ff", type=0x800) 

/ IP(version=4L, ihl=5L, tos=0x0, len=64,                 

id=0, flags=0, frag=0L, ttl=64, proto=UDP,              

chksum = 30495, src="xxx.xxx.xx.xxx", dst="xxx.xxx.x.x") /  

UDP(sport=31123, dport=31123, chksum=0x6f21, len=30) / Raw(load=Payload) )

Traceback (most recent call last):

File "EthCfgRx_Test_3.py", line 20, in

File "/home/watouser/.local/lib/python2.7/site-packages/scapy/packet.py", line 349, in div

return x.copy()

Any Advice?

Thanks in Advance!

Scapy will bind automatically the packets.

The wrong part seems to be Proto=UDP. Proto should be a number, not a class.

When doing the / operation, the Proto will be automatically provided, so you don’t need to specify it
