scapy> pkts = sniff (iface = "eth0", count = n), where n is the number of packets.
- What is the best way to send a packet with Scapy indefinitely every five seconds in the form of a loop?
scapy> sendp (packet, loop=1, inter=5)
- What is the method that must be invoked with Scapy to check whether a certain port (port) is open or closed on a certain machine (host), and also to show detailed information about how packets are being sent?
scapy> sr1(IP(dst=host)/TCP(dport=port), verbose=True)
- What functions are necessary for implementing the traceroute command in Scapy?
