I have updated the C code to be 100% universal. I added an auto-detection feature inside the C code itself. When the binary runs, it will automatically check whether it is on a Pi (/sbin/) or Ubuntu (/usr/sbin/) and route the traffic to the correct folder instantly. This means your never have to manually edit the C code!
Cross-Platform Performance Optimization: The Native C Wrapper
The Symptom: Network Lag and Packet Loss
While deploying an OS-level Bash script successfully prevents the RTNETLINK answers: File exists 10,000-session crash, it can introduce a new bottleneck in high-throughput environments.
Because an interpreted Bash script forces the CPU to open a heavy environment multiple times per second, the physical network interface can momentarily choke under the processing overhead, resulting in ping spikes and "Request timed out" errors during user authentication.
The Solution: A Universal Native C Binary
To eliminate the lag while retaining the protective mathematical armor, the interception logic must be compiled directly into native machine code. A C binary executes in a fraction of a millisecond with virtually zero overhead, passing the hexadecimal translations to the Linux kernel without interrupting packet flow.
The following deployment guide is designed to be fully cross-platform. It automatically adapts to both ARM architectures (Raspberry Pi) and x86 architectures (Ubuntu PC/Server).
Step-by-Step Deployment Guide
Step 1: Ensure Core Packages are Installed
Certain minimal server distributions (like Ubuntu Server) may be missing the core traffic control package or the C compiler out of the box. Force the system to install and verify them:
Step 2: Identify and Backup the Native Program
Depending on your operating system, the native tc program lives in a different folder. We will use a terminal variable to find it dynamically and safely rename it. Run these two commands exactly as written:
Step 3: Write the Universal C Source Code
Create a new C file in the home directory:
Insert the following highly optimized C code. This script includes an auto-detection block that automatically finds the tc.original file whether your system is a Raspberry Pi or an Ubuntu machine.
(Save and exit by pressing Ctrl+O, Enter, then Ctrl+X).
Step 4: Compile and Deploy
Use the GNU C Compiler to build the executable binary. The uppercase -O2 flag strictly optimizes the program for maximum execution speed. Using our terminal variable again, we drop the newly compiled armor directly into the correct system folder.
Post-Update Verification Check
Whenever your operating system undergoes a major apt upgrade, it is possible for Linux to overwrite this custom wrapper with a fresh, vulnerable copy of the native program.
Network administrators can perform a rapid file-size check to verify the armor is still in place. Run this command:
If the wrapper is active: The main tc file will be extremely small (approx. 17K), while the tc.original file will be massive (approx. 500K - 800K).
If the wrapper was overwritten: The main tc file will jump back up to 500K+. If this happens, simply repeat Steps 2 through 4 to re-apply the patch.

If in case you decided to remove the wrapper for any reason. You can do it with this:
To make sure you can safely remove the wrapper on any machine without having to guess the folder, here is the Universal Revert Method. It works exactly from previoous guide, but automatically detects where your system keeps its files.
The Universal Revert Commands
Run these three commands in order. The first command locks in the correct folder path, no matter which device you are using:
1. Find the path and delete the wrapper:
2. Restore the original native program:
3. Reboot to flush the kernel:
Once the system reboots, it will be 100% back to vanilla Adopisoft running the native Linux networking tools.
