The obvious approach I use Emacs + Org-mode for my note-taking workflow as a Cybersecurity Analyst. Emacs is my geeky cred at my job, plus it is genuinely useful. So one day when working on taking some repetitive notes on an incident I had a bright idea. Why don’t I just create a few templates that speed up my workflow? A demonstration of my workflow for capturing notes on an incident Incident --> Get Data --> Investigation --> Capture Templates --> Notes Expanding the approach Once I became comfortable with the approach of my capture templates, I expanded them to use the full power of Emacs and Org-mode!

This years BSIDES RGV was great! I had a lot of fun was able to meetup with a lot of old colleagues and meet some new interesting people.

I recently had the opportunity to add an ssl certificate in my homelab environment. It was really easy and only took one command in Linux. Once I created my ssl certificate all I had to do was upload it to NGINX Proxy Manager and have it serve it to my proxied sites. You can use any other proxy manager such as Caddy but I had NGINX Proxy Manager in my homelab environment. Read more...

Atreus Keyboard Figure 1: Atreus Keyboard from Keyboardio Ergonomics This keyboard is small and light. I found it to be an amazing size and shape. I don’t think it is too small or too close together I actually found it very comfortable. I did experience some fatigue in the beginning but that was from poor typing technique. I am a bit of a finger and touch typist. I tend to finger type with my left hand which made hitting keys like the C key really annoying because I’m used to lifting my left hand and pressing the C key with my left index finger. Read more...

I recently setup NGINX Proxy Manager to help manage all of my self-hosted services. How did I do this? I installed NGINX Proxy Manager in a LXC container in my Proxmox server. I then configured several of my services to route to their respective IP addresses and ports. In NGINX Proxy Manager you can assign local domain name to your services. I chose to go with something simple like example.home. Once I finished configuring NGINX Proxy Manager I moved over to configure my Pi-Hole server. Read more...

I recently decided to move away from Gitlab. There was a bit of news around Gitlab closing free accounts which I think is a fair business move by Gitlab. Businesses need to make money after all. Most of the internet decided that Gitlab as evil for doing this. But I didn’t in fact I think it’s for the best. Since I was barely even using my Gitlab account and most importantly I wasn’t paying for any services I felt that I was cheating Gitlab. Read more...

How do you stay organized with SSH connections? Most of us simply search our terminals history to find SSH connections. You may do history | grep "ssh" or even Ctrl+R and search SSH. While that may work for a few connections, there is a better way: SSH Config file. An SSH Config file simply tells OpenSSH how to open up connections. The benefit is that you can keep all your connections all in one place. Read more...

Enable SSH on Extreme Devices A key will be generated. To upload a public key simply use sftp or scp to upload key. But be sure to change the extension to .ssh for example id_rsa.pub will be id_rsa.ssh on the switch. Also you can assign a key to a user by simply appending the username to the key file for example admin.id_rsa.pub. Extreme switches have a limitation of only being able to use RSA or DSA keys.
