[Google recently announced][poodle] that there is an exploit in SSLv3, this vulnerability is know as POODLE. There is no other option than to disable SSLv3 in order to combat this major flaw. There have already been [guides on how to disable this in different servers][guides]. But nothing excised for Node.js yet, until now. In order to resolve this for Node.js we need to use various of undocumented options and modules.

In the index.js file below you can see an example of how you can protect your HTTPS server against the POODLE attack. It uses the secureOptions option to pass in constants in to the SSL context which is created by node.

What's driving me craziest right now is my monitoring system.

what I have right now

What I have right now is Nagios.
