    Python tool for seeing everything a LAN user is doing

    This is an open source python tool for seeing all interesting traffic from and to a client on your LAN. It's an asynchonous, multithreaded arp spoofing packet parser. It uses the Twisted framework, iptables nfqueue to feed the callback functions packets, and scapy for most packet dissection and injection.

    Simple usage:
    Code:
    git clone https://github.com/DanMcInerney/intercept
    cd intercept/
    python intercept.py -u -p -n




    -u: URLs visited; truncates at 150 characters and filters image urls since they spam the output
    -p: display username/passwords for FTP/IMAP/POP/IRC/HTTP, POSTs made, all searches made, and incoming/outgoing email and IRC messages sent
    -n: perform an doutput a very quick nmap scan of the target for open ports and operating system info

    Full usage:
    Code:
    python intercept.py -u -p -n -na -dns neopets.com -set -d -ip 10.0.1.20


    -na: perform an aggressive and complete nmap scan of the victim in the background including service enumeration. Saves results to <IP address>.nmap.txt in the working directory
    -dns DOMAIN: drop packets to DOMAIN and inject our own pointing the victim to the attack's IP address. This is especially powerful when combined with SET's web site cloning tool (option 1, 2, 3, 2, then enter the domain you're spoofing).
    -set: open the social engineer's toolkit

    Prereqs: Linux, scapy, python nfqueue-bindings, aircrack-ng, python twisted

    Tested on Kali 1.0. Please PM or reply with bug reports.

    goes fine until:

    Further to our above we are unable to load apt-get install -y python-nfqueue on our updated and upgraded kali1.05 hardrive installs(three computers). However it loads on all our persistent usb installs of kali1.05.

    I had the same issue, I then modified the sources.list to as below and able to install python-nfqueue

    deb http://http.kali.org/kali kali main non-free contrib
    deb-src http://http.kali.org/kali kali main non-free contrib

    deb http://http.kali.org/kali kali-dev main contrib non-free
    deb-src http://http.kali.org/kali kali-dev main contrib non-free

    deb http://security.kali.org/kali-security kali/updates main contrib non-free

    I am getting an error
    root@kali:~/intercept# python LANs.py -u -p -n[*] Running ARP scan to identify users on the network; this may take a minute - [nmap -sn -n 192.168.239.0/24]
    [-] Router MAC not found. Exiting.

    What am I doing wrong? My adapter is in mono mode and I have connected to my network via wlan0

    It would appear I have found the solution to some extent - I had been running reaver prior to running this script and had
    killed some of the services - after a reboot the script ran but although I am connected to my own network via a VM it does not
    show my computer name after the scan - all I get is three ip's one of which is the router with nothing else showing for the other
    3 ip's, is this normal?
