If you have administrative access to the machine where the port is
closed then you just have to change the rule that it's not letting
you log into the machine. If you don't have it then it's impossible
to open the port without using hacking techniques, and I'm not talking
about script kiddies techniques...

You can take a look at ntop, it has a nice web interface.
Or you can use a konsole with lsof -i -r 1, it's what I use
when I want to have a look at the connections in an easy way.
