About Me

I’m Luke Arntz. I’ve been working at service providers since 2001. I’m hands on with the wide range of technologies that make providing managed services possible such as Linux and Windows Server, virtualization, networking, SQL and almost everything in between. Reading and writing are passionate hobbies for me also. Twenty years ago I would have expected to write much more than I have over the years, and starting this website is the beginning of my quest to find my writing voice and fix that.

Install certbot on Amazon Linux

There is no packaged version of certbot for Amazon Linux so we have to download and set it up manually. Running it the first time will install all dependencies and should then work to create and renew certificates. Unfortunately, the first run on Amazon Linux gives us and error instead of a working certbot. :(

SSL for Websites

The goals of SSL/HTTPS are to provide a secure channel of communication. You should be able to trust that the SSL certificate you receive was actually issued to the website you are visiting and that it is non-trivial for a third party to read the data passing between the client and server.
