Creating a quick script where we can poll the services on a particular server to
verify if they are running or not. this will be included in a larger scope
application once the details are worked out.
Am having a problem getting results from queries to web server ports though.
Port 80(std), 8080(FP), and 443(SSL) either timeout without returning any
results, or error with some of the other attempts at illiciting a response that
we have tried (like specifying ssl:// prior to the hostname).
Code and two smaple outputs below. Thoughts?
