Limit wireless bandwidth (Evillimiter)

Evillimiter : Tool that Limits Bandwidth of Devices on the Same Network Without Access.

Evillimiter is a free and open source monitoring tool that can limit bandwidth usage for devices connected to LAN. Evillimiter runs on Linux and Windows, and can work without admin access to the network.

How to Install…

git clone https://github.com/bitbrute/evillimiter.git
cd evillimiter
sudo python3 setup.py install

Now, you’ll need to connect to your target network. Afterward, you can run Evil Limiter by typing evillimiter in a new terminal window. You should see something like below.

sudo evillimiter

evillimiter Commands

Command Explanation
scan (--range [IP Range]) Scans your network for online hosts. One of the first things to do after start. --range lets you specify a custom IP range. For example: scan --range 192.168.178.1-192.168.178.40 or just scan to scan the entire subnet.
hosts (--force) Displays all the hosts/devices previously scanned and basic information. Shows ID for each host that is required for interaction. --force forces the table to be shown, even when it doesn’t fit the terminal.
limit [ID1,ID2,...] [Rate] (--upload) (--download) Limits bandwidth of host(s) associated to specified ID. Rate determines the internet speed. --upload limits outgoing traffic only. --download limits incoming traffic only. Valid rates: bit, kbit, mbit, gbit For example: limit 4,5,6 200kbit or limit all 1gbit
block [ID1,ID2,...] (--upload) (--download) Blocks internet connection of host(s) associated to specified ID. --upload limits outgoing traffic only --download limits incoming traffic only.
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 192.168.178.24 or add 192.168.1.50 --mac 1c:fc:bc:2d:a6:37
monitor (--interval [time in ms]) Monitors bandwidth usage of limited host(s) (current usage, total bandwidth used, …). --interval sets the interval after bandwidth information get refreshed in milliseconds (default 500ms). For example: monitor --interval 1000
analyze [ID1,ID2,...] (--duration [time in s]) Analyzes traffic of host(s) without limiting to determine who uses how much bandwidth. --duration specifies the duration of the analysis in seconds (default 30s). For example: analyze 2,3 --duration 120
watch Shows current watch status. The watch feature detects when a host reconnects with a different IP address.
watch add [ID1,ID2,...] Adds specified host(s) to the watchlist. For example: watch add 6,7,8
watch remove [ID1,ID2,...] Removes specified host(s) from the watchlist. For example: watch remove all
watch set [Attribute] [Value] Changes current watch settings. The following attributes can be changed: range is the IP range to scan for reconnects. interval is the time to wait between each network scan (in seconds). For example: watch set interval 120
clear Clears the terminal window.
quit Quits the application.
?, help Displays command information similar to this one.
