Scapy

Tool for creating packets and packet manipulation

#Scapy..make me a packet
>>>packet=IP(dst="10.10.10.50")/TCP(dport=22)

#Scapy..send my packet, storing the response in a variable called response
>>>response=sr(packet)

#Scapy..look at my response
>>>response

#Scapy..look at first part of the first set of my response
>>>response[0][0]

Send packet with a payload

>>>packet=(IP(dst="10.10.10.50")/TCP(dport=22)/"thisisthetestpayload")

To make a loop (overflow)--once per second

>>>packet=IP(dst="10.10.10.50")/ICMP()
>>>srloop(packet)

Get packets from a pcap file

>>>rdpcap("[filename]",[packets])
