Selfishnet V0.1 Beta May 2026

The most famous bug: If the user had a slow CPU (common with Pentium 4 laptops), the ARP spoofing thread would consume 100% of one core. The system would overheat, the network card would reset, and SelfishNet would crash—leaving the user disconnected while the rest of the network recovered.

The following is a draft white paper for Selfishnet v0.1 Beta, a legacy network management utility used for controlling bandwidth allocation on local area networks (LAN). Technical Overview: Selfishnet v0.1 Beta

Date: April 26, 2026Subject: Local Area Network Bandwidth Management and Traffic Shaping 1. Abstract

Selfishnet v0.1 Beta is a lightweight, portable network utility designed for Windows-based systems to provide granular control over LAN traffic. By utilizing the WinPcap library, the software enables administrators to discover connected devices and manually throttle or block their upload and download speeds. This paper outlines its architectural dependencies, core functionality, and operational requirements. 2. Technical Prerequisites

Selfishnet is not a standalone executable; it operates as a wrapper for packet capture drivers. To function, the following must be present:

Packet Driver: Installation of WinPcap or Npcap is mandatory for the software to interface with the Network Interface Card (NIC).

Archiving Tool: Users must use tools like 7-Zip or WinRAR to extract the portable binary from its distribution archive.

Privilege Level: The application requires "Run as Administrator" permissions to execute low-level ARP (Address Resolution Protocol) spoofing commands. 3. Core Functionality

Selfishnet operates primarily through ARP Spoofing, allowing it to position the host machine as a "man-in-the-middle" between the router and other networked devices. Key Features:

Device Discovery: Scans the local network to list all active IP and MAC addresses.

Real-time Monitoring: Displays current bandwidth consumption (download/upload) for every detected node.

Bandwidth Throttling: Allows the user to input specific KB/s limits for targeted devices.

Network Blocking: Provides a "Block" checkbox to completely drop packets for specific devices, effectively disconnecting them from the internet without physical access. 4. Operational Workflow

Interface Selection: Upon launch, the user selects the active Network Interface Controller (Ethernet or Wi-Fi).

Network Discovery: Clicking the "Network Discovery" icon populates the device list.

Redirection: Clicking "Start Redirecting" initiates the ARP spoofing process, bringing all LAN traffic through the host machine. selfishnet v0.1 beta

Control: The administrator modifies the "Download" or "Upload" columns to enforce traffic shaping policies. 5. Security and Ethical Considerations

Selfishnet is frequently categorized as a "grey-hat" tool. While useful for troubleshooting network congestion, it can be used maliciously to deny service to others on a shared network. Modern routers with ARP Inspection or Source Guard may detect and mitigate Selfishnet’s activities.

This paper examines SelfishNet v0.1 Beta , a lightweight Windows-based utility designed for local network bandwidth management via Address Resolution Protocol (ARP) spoofing.

SelfishNet v0.1 Beta: Localized Bandwidth Control via ARP Spoofing

SelfishNet v0.1 Beta is a network management tool that provides granular control over shared internet bandwidth without requiring administrative access to a router. By utilizing ARP spoofing techniques, the software allows a single host to intercept, throttle, or block traffic from other devices on the same Local Area Network (LAN). This paper analyzes its architectural dependencies, operational mechanisms, and security implications. 1. Introduction

In shared network environments, high-bandwidth activities by a single user can degrade performance for others. SelfishNet was developed as a portable solution to this "noisy neighbor" problem. Unlike standard Quality of Service (QoS) configurations that require router-level access, SelfishNet operates entirely from the client side. 2. Technical Framework and Requirements

SelfishNet v0.1 Beta is built on a specific stack of Windows-centric utilities: Operating System: Compatible with Windows 7, 8, 10, and 11. Driver Dependency:

(or Npcap) to facilitate low-level network packet capture and injection. Framework: Necessitates .NET Framework 3.0 or higher. Privileges:

Must be executed with Administrative privileges to manipulate the local ARP table and send forged packets. 3. Operational Mechanism: ARP Spoofing The core functionality of SelfishNet relies on ARP Spoofing (also known as ARP poisoning): Network Discovery:

The tool scans the LAN to identify the IP and MAC addresses of all connected hosts. Packet Interception:

It broadcasts "bogus" ARP responses to the network, claiming that the host running SelfishNet is the default gateway (the router). Traffic Redirection:

Neighboring devices, believing the host is the router, redirect their outbound traffic to the host instead of the actual gateway. Throttling/Blocking:

The host then applies user-defined limits on upload/download speeds or drops packets entirely ("Blocking") before forwarding legitimate traffic to the real router. 4. Features and Limitations Key Features Real-time Monitoring:

Displays active IP addresses, MAC addresses, and current bandwidth usage. Capacious Control:

Users can manually input specific KB/s limits for both upload and download streams. Access Revocation:

A toggle switch to completely sever a device’s internet connection. Limitations Volatility: The most famous bug: If the user had

Settings are not persistent; they revert to default if the application is closed or the host machine is rebooted. Platform Lock-in: Native support is restricted to Microsoft Windows. Resource Intensity:

Redirecting all network traffic through a single PC can consume significant CPU and local bandwidth. 5. Security and Ethical Considerations

SelfishNet is frequently classified as a "grey-hat" tool. While useful for personal bandwidth management, its underlying mechanism is a form of network attack. Detection:

Modern antivirus programs often do not flag the binary itself, but sophisticated Network Intrusion Detection Systems (NIDS) can identify the ARP poisoning signatures. Mitigation:

Network administrators can defend against SelfishNet by implementing static ARP entries, port security, or Dynamic ARP Inspection (DAI) on managed switches. 6. Conclusion

SelfishNet v0.1 Beta remains a popular utility for users seeking immediate, router-less network control. However, its reliance on ARP spoofing makes it a disruptive tool that can be easily mitigated in professional or secured network environments. Users are advised to use such tools only on networks they own or manage to avoid violating acceptable use policies. defensive strategies

Selfishnet v0.1 beta

Log entry: Day 47 of solo survival in the Buffer Zone.

I didn’t mean to break the network. I just wanted a little more bandwidth for myself.

When the Collapse happened, the meshnet was supposed to keep everyone connected. Decentralized. Resilient. Every node shares, every node gains. That was the theory. In practice, people hogged, leeched, and lied about their relays. So I wrote a patch. A tiny fork of the routing protocol. I called it Selfishnet — version 0.1 beta.

It didn't disable sharing. It just prioritized my packets. My survival data. My map updates. My medical alerts. Everything else — neighbors' requests, emergency reroutes, the old lady two floors down trying to call her son — got shuffled to the back of the queue.

At first, it worked beautifully. My latency dropped. My scavenging routes updated in real time. I found clean water before anyone else.

But networks have memory. And selfishness is contagious. The following is a draft white paper for Selfishnet v0

Within three days, other nodes started behaving like mine. Not because they had my patch — because the network adapted. Packets from selfish nodes arrived faster, so relays learned to favor them. Altruistic nodes became invisible. Then irrelevant. Then dead.

By week two, the mesh had fractured into islands of mutual suspicion. No node trusted another unless it saw proof of selfish behavior first. My own logs showed my node talking to only four others — all running versions of Selfishnet they'd compiled themselves.

We didn't collapse the network. We optimized it. For a world where nobody helps unless forced.

Now I sit here, battery at 12%, listening to static. The last packet I received wasn't a map or a warning. It was a ping from a node I don't recognize. The payload?

Selfishnet v0.2 alpha — now with betrayal detection.

I should delete my patch. I won't. That's the problem with beta software. Once you see how the world really works, you can't uninstall it.

I’m unable to provide a complete academic or technical paper on “selfishnet v0.1 beta” because, as of my knowledge cutoff in October 2023 and my current search capabilities, there is no widely recognized software, protocol, or research project by that exact name in credible computer science, networking, or open-source literature.

However, I can help you in three ways:

Example (option 2):
Below is a template and partial draft of a paper on “SelfishNet v0.1 Beta” as a simulated network environment for studying selfish routing in mesh networks. You can adapt it to your actual project.

If you need to test network resilience or monitor traffic, use modern, ethical tools:

| Tool | Purpose | Why it’s better | | :--- | :--- | :--- | | BetterCAP | ARP spoofing, sniffing | Active development, supports IPv6, HTTPS bypass modules. | | Ettercap | MITM attacks | The industry standard. Still updated via Linux repos. | | Wireshark | Passive monitoring | No spoofing required. Just listen to your own port. |

Let’s be honest: This is ancient, unfinished code.

If you try to run it on Windows 10/11, you will likely see: "Failed to open adapter" or "WinPcap not found."
