scapy is python third-party libraries, it can also be called using the python alone use.
It can be very powerful for capture, analyze, create, modify, injected into the network traffic.
Use scapy
You can view detailed usage GitHub: https://github.com/secdev/scapy
Use ARP (). Display () calls this method, a custom ARP packet
hwtype hardware type
ptype protocol type
hwlen hardware address length
Protocol length plen
Operation op who-has arp query packet
hwsrc source MAC address
psrc source IP address
hwdst destination MAC address
pdst destination IP address
Compared to capture wireshark comparison
It can be obtained with the real scapy ARP packet structure consistent contrast.
By assigning a request for the required IP address in the ARP method scapy in pdst variable here as my gateway
Out here ready to release the assembled package, before premature opening of wireshark display filter through arp packet capture filters
There can be obtained according to the data packet analysis of this response obtained:
Protocol Type: ARP
Hardware type: 0x1
Protocol type is: 0x800
Hardware length: 6
Protocol length: 4
Action: Determine who is a host
Source mac address: 54: 66: 6c: 80: f3: 50
Source Host IP: 10.0.0.1
Target mac address: 00: 0c: 29: cf: 9f: 77
Destination IP Address: 10.0.0.8
padding: When the minimum packet length is still not satisfied all the fields added, the hexadecimal x00 will be fill bits.
The assembly has been caught ARP packets
