The command I can simply say netstat: http://linux.die.net/man/8/netstat

Man - page you surely going to need for reference. Just open a terminal with CTRL+ALT+T (If Ubuntu) and then changed to root user with

either

sudo -i

or su  -root

Then start now!!

1. How many ports you have in your System ? 

                            # netstat -a 

     2.  How may ports are listening now ?

                             # netstat -l

     3. What is the routing of your network ?

                            # netstat -r

      4. If a program/service access some port number , what is it ?

                         # netstat -ap | grep ftp
