Project description

The idea was a system which could monitor and provision a variety of network equipment. The primary target was cable modems and CMTS, but to do that the project had to contain more functionality

A DHCP server

The cable modem and customer computer equipment need IP addresses. I decided to use ISC DHCPd for this purpose, because it can dynamically serve config files based on MAC address (option 82). In addition, it's a very stable and capable DHCP server for all other equipment, beside cable modems.

A TFTP server

After a cable modem has received a response from the DHCP server, it will try to download a config file from a TFTP server. I decided to write this TFTP server in pure perl, because I could then build the config files dynamically from profiles stored in a backend. The profiles would be split into different segments, which mostly should default to a "most common" profile and then the bandwidth profile would be applied on top of that.

I started out with Net::TFTPd but realized that it was not easy to hook into and it wasn't all that effective. I then decided to write my own implementation called POE::Component::TFTPd, which I was quite pleased with. Even so it tried to make it even faster, which resulted in AnyEvent::TFTPd, but the module was shut down by the project owner of AnyEvent. If I was continuing the development, I would probably write a Mojo::IOLoop based version instead, since Mojolicious is a fantastic framework.

A collector daemon

I wanted the system to be plug and play, so the collector daemon would start out by probing the computers in the same network, checking if they could respond on SNMP requests. If they could they would automatically be added to the Quelea frontend, where the credentials (if any) would have to be added before the collector again started getting information from the various equipment. The collector would in the first place be "limited" to only supporting SNMP.

The most important data (imo) to collect would be:
