Nieco preplo sietovku do promiskuitneho rezimu. Vtedy sietovka prijima aj
ramce, ktore neboli adresovane jej (teda cely traffic). Mozu to vyuzivat
programy ako tcpdump a dalsie programy na analyzu sietovej prevadzky, tiez
tusim aj dhcp/bootp...
Problem by to mohol byt ak ten stroj niekto hackol a  spustil si nejaky
sietovy sniffer a odchytava traffic (hlada napr. prenasane nesifrovane
hesla a pod.).
