How to extract protocol from a pcap file ? - salwa17 - Apr-02-2020
I developed this code to extract all protocols (transport and application) from a pcap file:
load_layer('http')
load_layer('tls')
load_contrib("modbus")
def find_proto(s):
def expand(x):
yield x.name
while x.payload:
x = x.payload
yield x.name
if s[0]:
proto = list(expand(s[0]))
sProto = ["HTTP", "DNS", "ModbusADU", "TLS", "TCP", "UDP", "FTP-DATA", "Raw"]
for p in sProto:
if p in proto:
return p
return "Unknown"Here I limited the extract to "HTTP", "DNS", "ModbusADU", "TLS", "TCP", "UDP", "FTP-DATA", "Raw" but if I want to extract all the protocol like in wireshark
