Check a port

[kronnopio]

Hi.
I'm trying to use the check_port.pl or check_tcp command to verify host ports that are on the internet. In what way can I use a proxy to check it? Existing the $http_proxy variable does not work. Or do you know any script that does it?

Thank you!

Are you just checking websites through a proxy or is it some other type of listener on the other end? What I mean is the remote IP port combo going to return HTTP status codes or is it just a port check that you want to do through a proxy?
