I've installed a fresh Kali on my laptop a few hours ago, I updated everything and I edited Ettercap's pivileges to 0 yet I'm still having trouble. Ettercap seems to work fine but does not actually display the results: when I run my infected machine all the websites are still HTTPS and no results appear on my machine. Same thing with driftnet: it starts up all right but it won't display any images when the black window appears and I'm browsing google images on my PC. Any reply is greatly appreciated!
