Thanks Andy

so running this command tcpdump -i eth0 -s 1500 -w dump host www.example.com will give me the network traffic between src host to destination  host
and destination host to src host

is that correct what i understand

Thanks and Regards

Kaushal

You specified what you wanted too tightly... ONLY packets coming FROM
('src host') 192.168.0.1 and going TO ('dst host') www.example.com.

Just using

-i eth0 -s 1500 -w dump host www.example.com

will get you what you want: see

man tcpdump
