  • Setup Cloudflare DNS Proxy for Server

    Recently when setting my WordPress site, one of the requirements I wanted to meet was having a proxy server protect it. Basically, a proxy server is where another person’s server hides the original IP of the base server. For example, this image:

    In my case, I wanted my public IP to be not seen by using domain IP lookup tools. And possibly misuse it for malicious intents. (Such as DDoSing)

    After a little googling around, I discovered that Cloudflare had the free proxy option when you use their service. So I switched over nameservers to Cloudflare instead of GoDaddy nameservers, and it copied over the current DNS records. I just had to change the A record with the “orange cloud” enabled. The “orange cloud” is the switch on whether or not a DNS record has the proxy enabled or not

    above: Orange cloud means proxy is enabled, and grey is direct DNS enabled

    This tool can be handy for many hosting cases such as Minecraft Servers and Web hosting.

    I definitely recommend using Cloudflare for Proxy and DNS management, as they have many useful tools, including redirects for domains.

  • How to Fix URL Change When Hosting on Raspberry Pi – WordPress

    Recently when setting up my WordPress website on my Raspberry Pi, One mistake I made was to change the URL to the website to “192.168.1.24.com” instead of “192.168.1.24”, which means that if I try to connect to the website, it’s just going to redirect to a non-existent URL. Thus I could not connect to it via web address at all. But after about an hour of googling and researching, I was able to fix it, and here are instructions just in case you happened to run into the same issue:

    Instructions:

     

    First, ssh into your Pi, then type

    cd /var/www/wordpress/wp-content/themes/yourtheme

    (This changes the directory to the themes directory) and replace “yourtheme” with the name of your theme. Then type:

    sudo nano functions.php

    once in paste this code right after the “<?PHP” line:

    update_option( 'siteurl', 'http://example.com' );
update_option( 'home', 'http://example.com' );

    (this code overwrites the already chosen URL in the admin webpage) and, of course, don’t forget to replace the HTTP//:example.com with your desired URL. After that, press CTRL+X to exit, then hit Y to save the code. Now restart the Apache with:

    sudo service apache2 restart

    or if you are using Nginx, do:

    sudo systemctl restart nginx

  • Raspberry Pi 4 Octoprint Setup

    In the last few blog posts, I reviewed the RPI Night Vision Camera from MakerFocus and the OctoSlack plugin for Octoprint. Still, I will explain the troubleshooting and setting up of Octoprint ender-3.

    About two weeks ago now, I had found an old Raspberry Pi 7″ Touchscreen in my closet from my older brother. I instantly thought of setting it up with Octoprint, so I grabbed a Raspberry Pi and started researching using a touchscreen with Octoprint. I found a plugin called Octoscreen that is used for a Raspberry Pi Touchscreen for a user interface of Octoprint. I needed a plugin similar to this one because it will usually display the CLI (Command Line Interface) instead of loading an easy UI to use. So after a couple of tutorial watching, I got to work on setting up my Octoprint once again. Unfortunately, I ran straight into a problem. This was the same problem I have had before. The Raspberry PI would not connect to my Wi-Fi router. After about six hours, I got it to kind of work with an old Wi-Fi adapter, but after a restart the next day, it stopped working again.

    So instead, I ordered a new Raspberry Pi, the current one I was using was about seven years old because my brother Nicholas used to use it. Once the new Raspberry Pi arrived, after about 5 minutes of looking at it and its specs, I installed Octoprint on it, and after installing Octoscreen, everything was set. Except for printing the case. I found this case on Thingiverse and went straight to printing. Once it was finished printing, I put it together and added the final touches with also printing a case for the camera. It is now set up and ready to go.
