** A passive-aggressive network appliance designed to frustrate latency-sensitive gamers and make online games feel like they're haunted by the ghost of 2008 Wi-Fi. ** This tool uses tc netem and iptables to inject just enough jitter, delay, and packet loss into outbound UDP traffic to make competitive games frustratingly unplayable – without breaking basic web, video, or chat traffic. It's designed to run on a Raspberry Pi 3B+ with two network interfaces (e.g., built-in Ethernet and a USB-Ethernet adapter) acting as a transparent bridge or upstream router.

Because sometimes the problem isn't the network – it's who you're sharing it with.

• Maybe you're a parent with teenagers who have no idea ... absolutely no idea just what you’re willing to do with a bit of free time and a vibe-coding session with ChatGPT
• Maybe you're tired of bandwidth-hogging, voice-chat-screaming, chair-punching housemates.
• Maybe you're a troll with a conscience.
• Or maybe you're just curious what it feels like to weaponize latency without touching a firewall rule. Whatever your motive, this tool introduces plausible, periodic chaos into UDP traffic while leaving everything else mostly untouched. Your users will notice... but they probably won't understand why.

• Creates a NAT bridge between subnet (LAN) and uplink (WAN)
• Assigns static IP to subnet interface and enables forwarding
• Runs a dnsmasq DHCP server for the LAN side
• Configures a tc netem queue to inject:
  • Randomized delay (0–361ms)
  • Jitter (±5–19ms)
  • Packet loss (0–4%)
  • Probability-based "sanity windows" (occasional 0-delay bursts)
• Filters only UDP traffic, excluding DNS and DHCP

• Intercept or decrypt traffic
• Touch TCP flows (web browsing remains usable)
• Do anything useful for serious network engineering

• Known to run perfectly on a Raspberry Pi 3B+, but considering its simple mission in life this could probably run fine on lesser hardware
• 2 NICs (e.g., built-in Ethernet + USB-Ethernet)
• Debian or Raspbian Linux
• Internet upstream on uplink
• Downstream router or switch on subnet

[Internet] | [Modem or ISP Router] | [Pi Running frustrate-gamers.sh] | [Your Router / Wi-Fi Access Point] | [Victims] The Pi acts as a stealth inline router. Downstream devices get their IP from the Pi and route through it as if it's the gateway.

This is not a security tool. This is not ethical hacking. This is network satire in script form.

• This script flushes existing iptables rules - make sure the device is running behind a NAT or firewall.
• Do not run this on a production system unless you're very sure of what you're doing.
• UDP shaping may impact video-conferencing tools like Zoom or Teams. If the target network includes people who need to "work from home" you might be messing with someone's gainful employment.
• ChatGPT vibe-coding played a significant (who am I kidding, it played the primary) role in the creation of this tool. Short as it is, it still contains several anomalies and superfluous lines of code. Live with it ... or fork it and clean it up if it bothers you enough.
• Do not deploy on networks you don't own or control.
• Don't use this to sabotage people maliciously.
• You are responsible for how you use this. I just wrote the punchline.

1. Flash a Raspberry Pi with Debian or Raspbian Lite
2. Enable IP forwarding
3. Plug the uplink into eth0, the target subnet into eth1 (or your USB-to-Ethernet adapter)
4. Clone this repo on your Pi
5. Make the script executable.
6. Run it manually or install as a system service
