State of the Network: 2023

Welcome to AASullivan.com! I’ve been meaning to do this for a while, so here it is: The State of My Network. I’ve been planning to do an overview of my entire set up for some time now and I’ve finally kept everything in a consistent state now for a few months after many years of tinkering. A little background…

My home network (also known as my “home lab”) has been a long term project of mine to both try out new technologies and keep my skills sharp in a real server environment. It started in 2014 with a single server in my apartment running ESXI 3.5 on a system with a 6 core AMD CPU and 16GB of RAM. It was a blast to try new things (DNS server, file server, Plex, etc) and I’ve learned a lot since those times. My current Home Lab is considerably bigger now and is larger now than many small company systems; My poor power bill will never be the same. Let’s take a look at some of the set up!

Hacker’s Toolkit (2019)

As part of the security work I’ve previously done, I keep several tools on hand when out and about for reconnaissance and data gathering. The last BSIDESROC convention reminded me about some of the tools I haven’t used in a while so I figured I’d go over what’s in the bag!

Overly complicated ideas: IRC command of servers!

A little background: I get these ideas once in a while that eventually come to fruition after a couple months of brainstorming and tinkering. I’ve had the idea for a while of having a central way to maintain my fleet of Linux servers I host along with Windows if possible. In the past, I used ssh keys to login and run updates. It worked pretty well but I’d like a way to remotely run and/or monitor these. Enter IRC…

Most complicated home network ever…ever.

A little background:

I’ve been building and tinkering with computers since I was about 12, when I got my own laptop and desktop both from garage sales and began swapping parts, doing OS upgrades from floppy disks and doing whatever I could to tinker with them. Fast forward almost two decades, and I’m still at but on a much larger scale.

Monitoring System: Update 1

So I’ve been working with this project off and on, mainly off due to time constraints with a new work shift/promotion. I’ve split the logs and dashboard readouts to allow for easier pulling of individual data. What this allowed me to do was to couple this with WordPress using iFrame to load the individual pieces. I then set up multiple pages for each PHP document to allow the refreshes to work normally. I’ve build and gotten a working version of a single ping test, so that’s off the checklist. My next goal is to build a queue of sorts to pull information from for a polling cycle depending on type of test, then run the tests I want. I’m starting with ICMP, but hope to go for basic SNMP once this works out. Stay tuned as always!
