Legrand Home Automation DNS Change

We built our house a few years ago.  Before all the drywall went up I wired tons of networking into each room, including for for the Legrand Home Automation system and whole house audio.  The core home automation module, the HA7000, is the integration work engine of the system.  It connects to Legrand’s cloud servers for remote alerting, updating, etc.  On February 20th, 2018 they had a significant service outage and their restoration procedure is not so seamless.  Rather than following their instructions of changing my home router’s DNS forwarder I broke out tcpdump and did some digging.  So if you have a Legrand system, need to do this update, and don’t want to pass your DNS traffic to them, read on.

Welcome to my Blog

The Information Technology field is quite a unique space to plant roots for a career.  Very few fields have such open sharing of ideas, projects and aspirations as this field.  I have been quite fortunate to have entered into the IT space just as the Internet and online services were really becoming A Thing™.  I have always been amazed by just how eager fellow colleagues and peers are to share their ideas, scripts, projects, goals and accomplishments through both in person (conferences, work, over dinner) and through electronic mediums (blogs, forum posts, Slack channels).  Up until the beginning of this year I have been an in-office employee, which has afforded me the opportunity to share my knowledge and help empower others, just like those that helped me when I started out in this industry (thank you Russ).  I have always felt a great sense of satisfaction and pride when I can convey a topic to a colleague and recognize the light bulb go off.  However at the beginning of this year I embarked on a new opportunity, affording me the ability to work from my home office almost 100% of the time.  While this has granted me great changes in my work/life balance, it has to some degree removed my ability to share knowledge and exchange thoughts and ideas with others in my field.
