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 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.

I found myself going a bit crazy over theme rendering in my SSH sessions. Especially when I wanted to use emacs -nw in an SSH session. Recently I’ve been using GNU Screen as my terminal multiplexer and it comes with 256 color support. But you need to set it up and thanks to the Arch Wiki it’s rather easy. All you have to do is put term xterm-256color somewhere in your . Read more...
