Evillimiter - Limits Bandwidth Of Devices On The Same Network


A tool to limit the bandwidth (upload/download) of devices connected to your network without physical or administrative access.
evillimiter employs ARP spoofing and traffic shaping to throttle the bandwidth of hosts on the network. This is explained in detail below.

Requirements
  • Linux distribution
  • Python 3 or greater
Possibly missing python packages will be installed during the installation process.

Installation
git clone https://github.com/bitbrute/evillimiter.git
cd evillimiter
sudo python3 setup.py install
Alternatively, you can download a desired version from the Release page.

Usage
Type evillimiter or python3 bin/evillimiter to run the tool.
evillimiter will try to resolve required information (network interface, netmask, gateway address, ...) on its own, automatically.

Command-Line Arguments
Argument Explanation
-h Displays help message listing all command-line arguments
-i [Interface Name] Specifies network interface (resolved if not specified)
-g [Gateway Address] Specifies gateway IP address (resolved if not specified)
-n [Netmask Address] Specifies netmask (resolved if not specified)
-f Flushes current iptables and tc configuration. Ensures that packets are dealt with correctly.
--colorless Disables colored output

evillimiter Commands
Command Explanation
scan Scans your network for online hosts. One of the first things to do after start.
hosts Displays all the hosts/devices previously scanned and basic information. Shows ID for each host that is required for interaction.
limit [ID] [Rate] Limits bandwidth of host associated to specified ID. Rate determines the internet speed.
Valid rates: bit, kbit, mbit, gbit, tbit
For example: limit 4 200kbit or limit 2 1gbit
block [ID] Blocks internet connection of host associated to specified ID.
free [ID] Unlimits/Unblocks host associated to specified ID. Removes all further restrictions.
clear Clears the terminal window.
?, help Displays command information similar to this one.

Restrictions
  • Limits IPv4 connctions only, since ARP spoofing requires the ARP packet that is only present on IPv4 networks.
