mcbash

mcbash is a fast, modular and user-friendly script to find valid MAC addresses on some IPTV platforms.

Just feed it with a server URL or IP, and let it check by itself.

Quick start

git clone https://github.com/dougy147/mcbash
cd ./mcbash
sudo make install

Docker

git clone https://github.com/dougy147/mcbash
cd ./mcbash
docker-compose up -d
docker exec -it mcbash /bin/bash

AUR

For Arch users, there is an up-to-date mcbash package on the AUR.

Functionalities overview

As servers may differ in the way they handle requests, one need to adapt. The key feature of mcbash is flexibility. It comes with handy options to manage your requests.

Requests

Option	Functionality
-u, --url	Server's URL/IP
-w, --wait	Wait X seconds between each requests
-b, --break	Make a break every X requests
-d, --pause-for	Break duration (in seconds)
-s, --stop	Stop McBash after X tested MACs
-t, --timeout	Consider request a timeout after X seconds
-P, --proxy	Set the proxy URL (any authentication method supported)
-pu, --proxy-user	Set your proxy credentials user:password
--proxy-file	Read proxy IPs from a file. Rotation when request timeout
-EA, --enhanced-auth	Add SN and DevID1 to GET request (and save them if match)

Scan mode

Option	Functionality
--mac-file	Choose a file to read MACs from (MACs should be line by line)
--seq	Check MACs in sequential order (--range is forced)
--range	Set a range for checked MACs
-F, --from	Set range lower boundary (lowest MAC value to check)
-L, --to	Set range higher boundary (highest MAC value to check)
--prefix	Select MACs prefix when screening in random mode

Others

Option	Functionality
-k, --keep	Store expired MACs (valid addresses but expired accounts)
-np, --default	Don't ask for parameters. Use default configuration
--show-only-mac	Only outputs found MACs
--no-checkpoint	Don't store checkpoints

mcbash --help displays most common options.

For advanced settings, read the manual : man mcbash.

Scan randomly, sequentially, or from file

By default, MACs are pseudo-randomly generated and checked (random mode). If you want to screen sequentially, use --seq (sequential mode). You can also read MACs from a file (line by line) with --mac-file your_file.txt.

Scan inside a range

In sequential mode you need to specify lower and upper bounds of the range of MACs you want to scan (i.e. the "lowest" and "highest" MAC values). You can do that in random mode too, with the option --range.

Checkpoints

When screening sequentially, mcbash creates a checkpoint file, storing last checked MAC. You can specify --no-checkpoint to bypass that (i.e. no checkpoint will then be saved).

Proxy works

The use of a proxy and credentials is supported. Thanks to curl, any protocol works. Here is an example with proxy and credentials use : --proxy http://localhost:12345 --proxy-user user:pwd.

Default parameters

The configuration file $HOME/.config/mcbash/mcbash.conf contains default options. You can change them according to your needs.

MACs are stored

When a valid MAC is found, it is immediately stored in $HOME/.mcbash directory.

Misc

Size sometimes matters

For 00:1A:79:xx:xx:xx-like MAC addresses (most commons), there are $16^6$ possibilities (≈16.7million). Collision probability on sparsely populated servers is low by definition. So, there won't be too much matches on small ones!

macOS compatibility

macOS runs a dinosaur version of bash. But mcbash won't allow its users to be left behind. That's why its code is meant to stay retro-compatible. How kind from this little script 😎!

Usage examples

• Example 0 : mcbash

Easiest way to use it! mcbash guides you and adapts to your requests.

• Example 1 : mcbash -u my-fakedns.bla:8080 -w 1.5 -b 10 -d 3 -s 1500 -t 2

The program waits 1.5 seconds between each requests, makes a break every 10 requests for 3 seconds, stops after 1500 MACs checked, and considers a request timeouted after 2 seconds (timeouts trigger a pause to avoid flood).

• Example 2 : mcbash -u my-fakedns.bla:8080 -F 00:1A:79:00:00:00 -L 00:1A:79:00:11:11

Scans sequentially from 00:1A:79:00:00:00 to 00:1A:79:00:11:11.

• Example 3 : mcbash -u my-fakedns.bla:8080 --proxy http://localhost:12345 --proxy-user user:pwd

Establishes communications through proxy http://localhost:12345, with user:pwd username and password.

Instructions for the careless mind 🧠

Power is all relative, and this program's is pretty low; even quite harmless. However, I must release myself of any responsibility in the way you will use it. Indeed, its use might be unappropriate in your country.

As far as I understand (i.e. poorly), imperative programming is like stacking bricks on top of each other. If there's nothing wrong stacking, climbing the pile might. That way, it's unnecessary to say I'm only responsible for sharing a recipe one could find all the ingredients thanks to any search engine.

So, illegality is not contained in that program. It can only be in its user's behavior. Please use that script consciously, with and on your personal goods only.

Special thanks to contributors !

Feel free ! 😎

If mcbash has been of any help to you, I'd be glad and thankful !
