I already asked a question on stackoverflow and i got downvoted because it had to do with malware and appearently they don't really like that(Lol, fags) so i can't ask there anymore so i'll ask here instead.


import socket
import os
import struct
from ctypes import *

class IP(Structure):
    _fields_=[
        ("ihl",            c_ubyte, 4),
        ("version",        c_ubyte, 4)
        ("tos",            c_ubyte ),
        ("len",            c_ushort ),
        ("id",            c_ushort ),
        ("offset",        c_ushort ),
        ("ttl",            c_ubyte ),
        ("protocol_num",c_ubyte ),
        ("sum",            c_ushort ),
        ("src",            c_ulong ),
        ("dst",            c_ulong ),
    ]
    
    def _new_(self, socket_buffer=None):
        return self.from_buffer_copy(socket_buffer)
        
    def _init_(self, socket_buffer=None):
    
        # Map protocol constants to their names
        self.protocol_map = {1:"ICMP", 6:"TCP", 17:"UDP"}
        
        # Human readable IP addresses
        self.src_address = socketinet_ntoa(struct.pack("<L",self.src))
        self.dst_address = socket.inet_ntoa(struct.pack("<L",self.dst))
        
        # Human readable protocol
        try:
            self.protocol = self.protocol_map[self.protocol_num]
        except:
            self.protocol = str(self.protocol_num)

I'm getting a type error in my class, appearently my tuple object isn't callable and i don't know why, this is supposed to work from what i read/understand.


Traceback (most recent call last):

Try removing the comma from your last array value and version seems to be missing a comma, add one to that, too:


class IP(Structure):
    _fields_ = [
        ("ihl", c_ubyte, 4), 
        ("version", c_ubyte, 4), 
        ("tos", c_ubyte), 
        ("len", c_ushort), 
        ("id", c_ushort), 
        ("offset", c_ushort), 
        ("ttl", c_ubyte),

Thanks that was it, i have no idea how i missed that, lol. I don't know if you're interested but i feel like sharing anyway, while i was waiting for an answer i wrote the rest the program. I'm making a network sniffer but i got an error in my main loop.


sniffer = socket.socket(socket.AF_INET, socket.SOCK_RAW, socket_protocol)

sniffer.bind((host, 0))
sniffer.setsockopt(socket.IPPROTO_IP, socket.IP_HDRINCL, 1)

if os.name == "nt":
    sniffer.ioctl(socket.SIO_RCVALL, socket.RCVALL_ON)

    
try:

    while True:
        # Read in a packet
        raw_buffer = sniffer.recvfrom(65565)[0]
        print raw_buffer
        # Create an IP header from the first 20 bytes of the buffer
        ip_header = IP(raw_buffer[0:20])
        
        # Print out the protocol that was detected and the hosts
        print "Protocol: %s %s -> %s" % (ip_header.protocol, ip_header.src_address, ip_header.dst_address)

            # Make sure host is in target subnet
            if IPAddress(ip_header.src_address) in IPNetwork(subnet):
            
                # Make sure it has our magic message
                if raw_buffer[len(raw_buffer)-len(magic_message):] == magic_message:
                    print "Host up: %s" % ip_header.src_address
        
# Handle CTRL+C

    # If we're using Windows turn off promisuous mode
    if os.name == "nt":
        sniffer.ioctl(socket.SIO_RCVALL, socket.RCVALL_OFF)


raw_buffer = sniffer.recvfrom(65565)[0]

'raw_buffer' should have an integer as a value and


sniffer.recvfrom(65565)[0]

Is supposed to put out an integer but if i print the value of raw_buffer i get this.

What OS/bit are you using?

What OS/bit are you using?

I'm testing it against Windows, it should be able to decode IP headers and take apart ICMP(I got a class for that as well) but it should run in Linux no problem. I got some logic that checks to see if we're in a Windows environment and if so adjust the behavior of the program accordingly. If you think it would helpful, i could post the entire script.

just responding to OP cuz.

It's the missing comma on line 9. A tailing comma has no semantic significance in a list. It does in a tuple, but only if the tuple has one item (it's how a tuple is distinguished from parentheses indicating operator precedence)). It's taking line 9 as an expression which is expected to evaluate to a function reference and then calling it on the following tuple. Consider:

def inc(x):
  return x: 1

mylist = [(inc)(1)]

`mylist` will be `[2]` (a list with the single member, the value of inc(1), that is 2).

s.ioctl(socket.SIO_RCVALL, socket.RCVALL_OFF)

What do you think this code does spectral and how do you think this is helpful? The purpose of my program is to discover hosts decode the IP header, receive and decode the ICMP response, send out UDP datagrams and interpret the response. The only thing your bit of code does is print a coded response from a host.

Also you're commenting completely wrong.


# the public network interface
HOST = socket.gethostbyname(socket.gethostname())

This isn't 'the public network interface' this code just sets the value of HOST to a socket on your local IP on the subnet, e.g.192.168.0.1.


# receive all packages
s.ioctl(socket.SIO_RCVALL, socket.RCVALL_ON)

This turns promiscuous mode on, on Windows.


# receive a package
print s.recvfrom(65565)

This doesn't receive a package it simply prints the response from whatever you're talking to.

ip_header = IP(raw_buffer) and see if that makes a difference

I only need the first 20 bytes though that's what the [0:20] is for. And if the response is not an integer when i receive the first 20 bytes it's not going to be an integer if i receive all of them either, i'd think.

Print out the result of the raw buffer and see what it returns

Also, is your subnet not supposed to have a period after 192?
subnet = "192168.0.0/24"
