How to trace networking activity of a command?

I want to trace the networking activity of a command, I tried tcpdump and strace without success. For an example, If I am installing a package or using any command that tries to reach some site, I want to view that networking activity (the site it tries to reach). I guess we can do this by using tcpdump. I tried but it is tracking all the networking activity of my system. Let's say if I run multiple networking related commmands and I want to track only particular command networking activity, that time it is difficult to find out the exact solution. Is there a way to do that? **UPDATE:** I don't want to track everything that goes on my network interface. I just want to track the command (for an example #yum install -y vim) networking activity. Such as the site it tries to reach.
