Establishing connection between the host and the target

I am trying to run a simple hello world program on the jetson tk1. I am using the nsight eclipse edition. I am trying to add the target system by going to Myproject -> properties -> build -> targetsystems. When I click manage I get a box that asks for host name, username, port number. Can someone help me in establishing the connection between host and the target.

Host name is what? Ip address of my host system or the jetson target or something else?
Also how do i figure out the port number?
