Marlin 1.1.19 on Kossel Mini with ZProbe

AONeil

I got into 3D Printing about two years ago, my first printer was an wanhao i3 with a 200mm x 200mm x 180mm bed. It served me well for about a year and then I wanted more. In comes the Kossel Mini, with a 175mm x 175mm x 300mm bed size. So much room for vertical printing activities!

This post is going to be about my on-going project to setup my 3D Printing enclosure that I have built over the last year. This project is far from done however, I would like to share my setup at this point to hopefully give someone an idea of the Kossel Mini setup.

Now CCNA certified!

AONeil

After months of studying, I am proud to say I am now CCNA certified. I would like to say thank you to David Bombal and his courses on Udemy. I also spent alot of time watching CBT Nuggets and watching Paul Browning’s CCNA cram.

I spent some time reading through the Cisco official ICND2 book however, I found the material kind of dry and found myself not reading through everything in the chapters. So if you love raw material, go for the Cisco official book. Otherwise, I recommend reading through Todd Lammel’s “CCNA Routing and Switching Complete Study Guide”

All in all, it was a long and difficult study period for the last few months but I believe it was well worth it. Onto the next certification!

Defcon 27 – After thoughts

AONeil

So hacker summer camp is over and it’s time to get back to reality. This was my first Defcon and it was amazing. I learned alot, got some ideas for new projects, and met some new friends. I didn’t grab as many pictures as I’d like to hope but I would like to show one; the “Ohio Defcon meetup” group that we had.

This trip made me realize that I have alot of learning and tinkering around to do to make myself better as an infosec professional.

Next year, I plan to partake in some CTFs and events, until then… I will be studying.

Unraid on a Dell R510 – How to install and get started

AONeil

After years of running Windows Server as my primary server OS for my homelab, I am starting to branch away and go different routes with how I want my homelab to function. In the past, I had Windows Server 2012R2, 2016, and 2019 with a software called stablebit drive pool to pool my JBOD setup into one network share. While this served its purpose, I recently replaced my laptop OS from Windows back to glorious Linux and Windows SMB for file shares wasn’t cutting the bill. This blog post is the journey of getting Unraid onto my Dell R510 outfitted with 35TB of spinning disks.

Domain Password Spray by Dafthack

AONeil

At the time of writing this, we do not have very much in place to enforce what passwords can and can’t be used on the network aside of the standard group policy controls. In the past, I used to gather AD Password hashes from the domain controller and then run the password through hashcat in order to give me a list of user passwords; The Domain Password Spray Powershell script from Dafthack changes everything.

Grafana on Ubuntu Server 18.04 | InfluxDB / Telegraf

AONeil

Recently, I setup Grafana at my workplace to allow more visibility on our network. In the past I have played with Grafana in my homelab but I didn’t understand how It could be useful for me at the time when I only had one server. Now that I have a handful of servers that can be a pain sometimes to monitor, I’ve decided to give Grafana another go.
