1 Hi Grant,

3 personally (but this is by far only ONE possible setup for your task)
4 I'd advise you to connect eth0 to wan through a box set up as a bridge
5 (try brctl). If that box has a good wireless card and good drivers (this
6 mostly means "if that box isn't running Windows") you can also put that
7 wireless-card into promiscuous mode lock it to your chanel and ssid and
8 feed wireshark your WEP-Key or WPA-PSK for decryption.
9 If not, then you'll have to use a second box for the wireless sniffing.

11 BTW. current rootkits won't just replace ps or some other tools. Good
12 rootkits do not run in userspace; they run in kernelspace. They directly
13 intercept the function-calls. Just another thing to keep in mind while
14 trying to scan for them.
