sniff traffic on a particular port using scapy
14,646
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.

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 ?
