I have a completely noob question. I want to see all packets that come to my computer from particular site (google.com). So I start tcpdump sudo tcpdump -i eth0 host google.com and enter google.com in a browser and hit enter - nothing gets captured. I can't figure out why it happen. What do I do wrong? Edit It appeared that I was listening to the wrong interface. I had changed eth0 to any and it worked. It was ppp1 that needed listening. Thanks for your answers!
