This is the introductory article, from a series of five, in which I will write about the main VoIP providers that operate in my country and I have used or I’m currently using.
This will be of much help to those of you who want a free RO number for various reasons (you have left the country, you need a landline number that resembles a pre-pay SIM, etc.)
I will start with some details about the VoIP technology. First of all how is it possible to even get a landline Romanian number without staying in the same country? Well the answer is simple: Internet! The “telephone” – the server that holds your telephone number can be accessed for free* via the Internet thus reducing the install costs of a new line almost to 0.
In this article I wish to mark some advantages / disadvantages of having a WMI proxy in your Nagios setup.
To WMI or not to WMI….
First we need to explain what exactly a WMI proxy is. Basically this machine is a Linux/Windows machine with a Nagios client installed that runs as a service. This WMI proxy has some scripts (I will detail them in my next post) capable to check other Windows servers with the help of the WMI repository located on each Windows server. The same technique is applied with success by SCCM, SCOM, SpiceWorks, etc.
