A Self Hosted Server Health Check
I’m not big on creating dashboards. I find that I don’t look at them enough to warrant hosting the software on an instance and having to have the browser open to the page all the time. Instead, I prefer to be alerted via Slack as much as possible. I wrote scripts to collect DNS records…
Where Is It 5 O’Clock Pt: 4
As much as I’ve scratched my head working on this project it has been fun to learn some new things and build something that isn’t infrastructure automation. I’ve learned some frontend web development some backend development and utilized some new Amazon Web Services products. With all that nice stuff said I’m proud to announce that…
Where Is It Five O’Clock Pt: 3
So I left this project at a point where I felt it needed to be re-architected based on the fact that Flask only executes the function once and not every time the page loads. I re-architected the application in my head to include an API that calls the Lambda function and returns a list of…
Where Is It Five O’Clock Pt: 1
I bought the domain whereisitfiveoclock.net a while back and have been sitting on it for quite some time. I had an idea to make a web application that would tell you where it is five o’clock. Yes, this is a drinking website. I saw this project as a way to learn more Python skills, as…

Discovering DHCP Servers with NMAP
I was working at a client site where a device would constantly receive a new IP address via DHCP nearly every second. It was the only device on the network that had this issue but I decided to test for rogue DHCP servers. If someone knows of a GUI tool to do this let me…
Amazon S3 Backup from FreeNAS
I was chatting with my Dad about storage for his documents. He mentioned wanting to store them on my home NAS. I chuckled and stated that I would just push them up to the cloud because it would be cheaper and more reliable. When I got home that day I thought to myself how I…
Lessons Learned from Migrating 17TB of Data
I finally pulled the trigger on some new hard drives for my home NAS. I am migrating from a 5U Server down two a small desktop size NAS. Ultimately this removes the need for my 42U standing rack. I did this transfer a year or so ago when I did a full rebuild of my…
