Evillimiter – Tool To Control Network Traffic/Bandwidth And Block Devices Without Access

Evillimiter - Tool To Control Network Traffic or Bandwidth And Block Devices Without Access

WiFi connections is everywhere, maybe yo have one on your house. If your house have a WiFi, your friends or neighbors is come in your house and use that WiFi to play game, upload, download, watching movies or anything. Sometimes, because a lot of people use same WiFi, the connection speed is decreases.

You can limit all of them from download or upload and also block someone devices to use your WiFi connections with tool called “Evillimiter“. This tool can limit bandwidth of someone without special access to the router for setting up first, you can do that just with your computer on the same network. Control your network traffic and kick devices without being noticed.


Evillimiter is 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.


  • Linux distribution
  • Python 3 or greater

Possibly missing python packages will be installed during the installation process.


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.


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

-hDisplays help message listing all command-line arguments
-i [Interface Name]Specifies network interface (resolved if not specified)
-g [Gateway IP]Specifies gateway IP address (resolved if not specified)
-m [Gateway MAC]Specifies gateway MAC address (resolved if not specified)
-n [Netmask]Specifies netmask (resolved if not specified)
-fFlushes current iptables and tc configuration. Ensures that packets are dealt with correctly.
--colorlessDisables colored output

Evillimiter Command

scan (--range [IP Range])Scans your network for online hosts. One of the first things to do after start. For example: scan --range or just scan to scan the entire subnet.
hostsDisplays all the hosts/devices previously scanned and basic information. Shows ID for each host that is required for interaction.
limit [ID1,ID2,...] [Rate]Limits bandwidth of host(s) associated to specified ID. Rate determines the internet speed.
Valid rates: bitkbitmbitgbittbit
For example: limit 4,5,6 200kbit or limit all 1gbit
block [ID1,ID2,...]Blocks internet connection of host(s) associated to specified ID.
free [ID1,ID2,...]Unlimits/Unblocks host(s) associated to specified ID. Removes all further restrictions.
add [IP] (--mac [MAC])Adds custom host to host list. MAC-Address will be resolved automatically or can be specified manually.
For example: add or add --mac 1c:fc:bc:2d:a6:37
clearClears the terminal window.
quitQuits the application.
?helpDisplays command information similar to this one.


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

Limit or Block Devices

After we successfully install “evillimiter”, now we can control our network traffic. First we need to find devices on the network, you just to type scan the scan will get other hosts that connect with our WiFi.

To show them all type hosts

Evillimiter show hosts xploitlab

If you want to limit every device except the router, you can list them off one by one after the limit command. You’ll also have to specify the speed you want to limit them to. In my case, I’ll go with 200kbit as the limiting speed.

You could use the limit all command to choose everything, but because you want to exclude the router, type the command limit 1,2,3,4,5,6 instead to begin limiting those specific devices. The amount of devices you list depends on how many you found.

Now, selected devices is limited, the bandwitdh that they can use is maximum 200Kbit. We can also select any devices we want to block entirely from accessing the network.

To block a device, type the block command, then the number of any device you want to prevent from receiving data over the network.

And then type hosts second time, the selected hosts should be blocked

Restore To Normal Connection

After we make chaos on the network, it’s time to set things back the way they were. Fortunately, doing so is easy. You can choose to either restore devices one by one or run free all to undo any limitations on network devices.

Run hosts a third time, all hosts on the network should be normal again.
