![]() ![]() Once we have the SNMP client software installed on the agent it will expose a set of variables to the management console which then allows us through these variables to update configuration and similar. Or perhaps we wish to perform the same task on a firewall!Įach of these devices represent agents on our network. If we build out our own server which acts as the management console for our home automation devices, it would be good to gather data on it and alert us if we need to administer it in some fashion. A range of devices from servers to printers support the protocol and this list of devices also includes pfSense. Our pfSense firewall supports the protocol known as SNMP (Simple Network Management Protocol) which allows us to do exactly that over a TCP/IP network. Many tools exist out there, but we will be experimenting with this one in particular since it is easy to install for learning purposes.įor those interested it operates at Layer 7 of the OSI-7 Layer model (the Application layer). This post will form the foundation for future ones which dive into the subject further. In this post we are going to provide a brief introduction on ow to do this. It’s useful to be able to monitor devices on our network for a variety of reasons including security and performance issues. ![]()
