Network Device Change Control 3.10

Network Device Change Control (NDCC) is a system that monitors and records changes to the configurations of network equipment.

Network Device Change Control can store configuration snapshots for any text-based configs. It has been used to store configurations from Unix and Linux systems, Cisco routers, switches, load balancers, and firewalls, Foundry, NetScreen, Juniper, NetScaler, and others.

It only took a while to realize that router changes should be tracked. I rewrote the system to give a current and once-back system of configurations. Since I was using diff, I decided to leave the diff information in the system. Those diffs were emailed to a group so everyone knew when something was changed, along with what was changed.

Some time later, a bank needed to track configuration files, and the system was upgraded for use within a database. The first implementation was using perl as a CGI script against a PostgreSQL database. The company wanted many changes made for their auditing needs and most of those changes enhanced NDCC. Upgrades to their environment moved things to PHP and MySQL, and the system was rewritten for that environment and the old perl code has since been lost.
