Ok so I have client and a server code.
The server code looks like this :
import socket
import sys
HOST = ''
PORT = 5555
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print 'Socket created'
#Bind socket to local host and port
try:
s.bind((HOST, PORT))
except socket.error as msg:
print 'Bind failed. Error Code : ' + str(msg[0]) + ' Message ' + msg[1]
sys.exit()
print 'Socket bind complete'
#Start listening on socket
s.listen(10)
print 'Socket now listening'
#now keep talking with the client
while 1:
conn, addr = s.accept()
print 'Connected with ' + addr[0] + ':' + str(addr[1])
data = conn.recv(10000)
print data
s.close()
Now what I wanna be able to do is to conduct some analysis on these incoming packets on that socket (port 5555). Basically I want extract header flags. I was trying to do this using scapy function sniff() as found here Fetch source address and port number of packet - Scapy script
only i wanna be able to just sniff packets coming in on that port .. not any other traffic.
How do I go about doing this ?
The following will capture all packets with destination port number equal to 5555 on all available interfaces.
sniff(filter = 'dst port 5555')
You can of course specify the interface that you wish to sniff on by specifying the iface parameter.
