    Currently I'm on BT4, however try this - open a Konsole and type
    Code:
    tcpdump -h
    and also
    Code:
    man tcpdump

    Just log into your router, usually it's 192.168.1.1 or 192.168.0.1. Then look for "Attached device" - you can see all the computer that are using/stealing your internet.

    thank you for your help.
    i tried tcpdump -i wlan0 which then showed me some traffic when i navigated to google.com. i could clearly see my ip and laptop name but i couldnt see my mac address. is this normal?
    also i had another quick play with ettercap and my router (default gateway is 192.168.1.254 do i put this in section 1 or 2? i put both my router and my other laptop into the same section (1) and then when i navigated to myyearbook it showed my password and login but im not sure if that would work with someone else who is conected to my router. sorry to be a hassle but thanks in advance

    Well if someone is using your wifi why not just lock it down with wpa2 aes or the like?
    Not to mention as was stated the router's web iface should be able to tell you all you need to know.
    tcpdump and the like seems to be a bit overkill for what you are trying to do.
