+While many methods of sending files online exist, scaling file sending to accomodate larger and larger files can be a problem due to constraints on bandwidth, connection reliability and maintaining file integrity. To solve some of these issues, the technology of torrenting was born. At its core, torrenting simply involves taking a large file, breaking it into smaller chunks, transmitting those smaller chunks from one peer to another (hence P2P), and having the receiving party reconstruct those smaller chunks into the original file. The advantages here are that this process is decentralized, can be interrupted/resumed, and leechers can simultaneously download from multiple seeders thus speeding up the process. This process inherently relies on users' IP addresses for file transmission which are visible to anyone participating. As such, we must take precautions using a VPN to mask this information. In this article, we will explore how, after binding a VPN to their torrent clients, Sam the Seeder can privately share a large file with Larry the Leecher.
-<!-- Ever since people started communicating online, (the need for transmitting files to one another quickly emerged) they quickly realized a need for transmitting files to one another. While many methods of sending files came to exist, scaling file sending to accomodate larger and larger files became a problem due to constraints on bandswidth, speed, and connection reliability. Maintaining the integrity of large files during long transmission times became challenging and from this problem, the technology of torrenting was born. At its core, torrenting simply involves taking a large file, breaking it into smaller chunks, transmitting those smaller chunks from one peer to another (hence P2P), and having the receiving peer reconstruct those smaller chunks into the original file. The advantages here are that this process can be interrupted, is decentralized, and leechers can simultaneously download from multiple seeders thus speeding up the process. Even though torrenting is decentralized, it is important to keep in mind that this process inherently relies on users' IP address for file transmission which is visible to anyone participating. As such we must take precautions using a VPN to mask this information. In this article, we will explore how, after binding a VPN to their torrent clients, Sam the Seeder can create a torrent file and share a file with Larry the Leecher. -->

 Sam is now ready to share a file with Larry. He has a 10GB file of "linux ISOs" for which he will need to create a .torrent file. To help with this, Sam will use <a href=https://privtracker.com target=_blank>PrivTracker</a>, a private BitTorrent tracker, to announce his .torrent file. Sam generates a private announce URL on the PrivTracker website and copies it to his clipboard.

 </p>
 
+<p>
+Additionally, it is possible to self-host PrivTracker on a VPS. Following the instructions on their <a href=https://github.com/meehow/privtracker target=_blank>GitHub</a>, we need to run:
+<pre>
+<code class="nim">
+Build
+
+# Clone this repository.
+$ git clone https://github.com/meehow/privtracker.git
+
+# cd into the directory
+$ cd privtracker
+
+# Run go build
+$ go build
+
+Usage
+
+# Runs on port 1337 and redirects to privtracker.com by default.
+$ ./privtracker
+
+# Export PORT and DOMAIN variables to use custom values.
+$ export PORT=12345 DOMAIN=customprivtracker.com; ./privtracker
+</code>
+</pre>
+</p>
+
 <p>
 In qBittorrent, Sam will go to Tools -> Torrent Creator. He selects the desired file, checks the box to make it a private torrent, clicks the box to start seeding immediately, pastes the previous copied announce URL in the Trackers URLs section and clicks on Create Torrent. Once the process finishes, he clicks OK.

 Larry adds the .torrent file to his qBittorrent client to begin downloading the 10GB file. Under File -> Add Torrent File, Larry selects the .torrent file he received and clicks Open. Larry chooses where to save the 10GB file then clicks OK.
