tcpdump

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!

Packet loss rate with iperf and tcpdump

as seen on Server Fault - Search for 'Server Fault'
I tested a line for its link quality with iperf. The measured speed (UDP port 9005) was 96Mbps, which is fine, because both servers are connected with 100Mbps to the internet. On the other hand the datagram loss rate was shown to be 3.3-3.7%, which I found a little too much. Using a high-speed transfer… >>> More
