Tools To Implement a Sniffer on the Local LAN or WLAN :

To implement Man in the Middle attack we need some Applications like sniffer Tool, Packet analyzer, Network identifier.To get this Tools see the bellow list and Download the Applications from there.

1) Nmap      –  You can Download this from  nmap.org

  3. Hello,

    This Tutorial is useful and awesome.

    But I’m afraid I can’t comment nicely but have a small problem, about 3 weeks ago my wlan connection to a public network (a hotel) works just fine, but now suddenly the signal is disappear and the smaller ssid’s derivative from the main signal (looks like numbers of hotel room) not disappeared but I couldn’t connect to any of them.

    fyi. my wlan chipset is broadcom on a HP pavilion G4 notebook PC (not linux).

    Any help would be greatly appreciated. Thank You in advance.
