Hello, I need help creating a TCP SYN packet in Scapy. It can have any IP source and destination address, and any TCP source and destination address (for the example, just use the address 127.0.0.1 for source/destination). I need this packet to be sent and received using the sr() function of Scapy. Thank you kindly!
