Rewrote netstat commands as Popen piped commands
Rewrote netstat commands as Popen piped commands

The original version actually failed for me. I am led to believe that all the pipes were being
passed to netstat as it said "I don't understand the option ':'" which came from the cut command.
At the cost of simplicity, this should do what we want properly. Alternatively we could move the
awk/cut/sort into python.
