    Hi guys,

    I want to use a raspberry pi to monitor all traffic on my home LAN. Incoming / outgoing connections and websites visited.

    Can you recommend some open source software to achieve this.

    Thanks

    Loads of them - just go

    apt-get install ( name of thingy )
    iptraf

    tcpdump

    ntop

    ^^^^^ if you are passing traffic through the Pi ( using say a USB to ethernet converter)

    http://www.ebay.co.uk/bhp/usb-to-ethernet-adapter

    List here :

    https://wiki.debian.org/Network_Monitoring

    ( will add more in a bit )

    NSA for your home :eek: How are you proposing to monitor wireless devices? You would really need a router based solution to capture ALL traffic.

    Once I'm up and running you're more than welcome to use my network :pac::pac:

    Seriously, it's more of a project than anything else. If a wireless device is connected to my wifi Im hoping some of the suggestions from gctest50 will capture the traffic as the gateway will be the same.

    I just hope the pi doesn't cause a bottle neck.

    A bit of wiring and you could make an ethernet tap and put it between the wifi-box and your modem
    or get a network switch that can do monitoring on a port
    or get an old hub ( fsckerzs 2 way traffic a bit though) ( will spray everything out all ports)


    Advantage to passing traffic though a fairly quick box is you can alter packets n stuff
