transport = TCP(dport=53, flags = 'S')

Here we pass the destination port and the flag is set to S for a SYN packet. We can also pass the destination ports as a list for creating multiple packets:

transport = TCP(dport=[(53, 100)], flags = 'S')

Next we can stack these layers with the / operator:

packet = ethernet/network/transport

Now we can check the packets generated by printing them with pprint:

pprint([pkt for pkt in packet])

We can also use ls() to inspect a packet:

for pkt in packet: ls(pkt)

Another option to get the packet details is the show() method in the packet:

for pkt in packet: pkt.show()

Now we can create a single packet with a script. The script will be as follows:

from scapy.all import * from pprint import pprint ethernet = Ether() network = IP(dst = ['rejahrehim.com']) transport = TCP(dport=[(80)], flags = 'S') packet = ethernet/network/transport for pkt in packet: pkt.show()

This will create a TCP/IP packet with the SYN flag set, the destination address https://rejahrehim.com/, and the destination port 80.

Now run the script with the sudo permission:
