Tethering from Android to Android via USB cable

• Tethering device: The device sharing its internet connection.
• Tethered deivce: The device want to connect to the Internet via 'tethering device'.

Install for tethering device

• Termux: Install from Github.
• Termux-API: Install from Github

1. Clone the repository git clone https://github.com/AlphaBs/termux-gnirehtet
2. Run pkg update && ./install.sh.

Usage

1. Make sure USB debugging is enabled on the tethered device.
2. Connect two Android devices with USB cable.
3. Set USB control mode:
   • Tethering device: USB controlled by connected device
   • Tethered device: USB controlled by this device
4. Allow file system access and USB debugging authorization.

5. Run adb devices on the tethering device to check the tethered device is connected. (it may take 1-2 minutes)

6. Run ./gnirehtet run on the tethering device.

How it works

gnirehtet was originally for reverse-tethering, sharing PC's internet connection to Android device, using adb. I recompiled gnirehtet to make it executable on aarch64 Termux.

To run adb and connect to another device on Android, I used termux-adb.

Build

gnirehtet relay server

The binary of relay server (gnirehtet) in this repository was built for Termux, aarch64. However, you may want to build relay server yourself to run on difference environment.

To build relay server:

1. Install cargo to build Rust.
2. Run build-gnirehtet.sh script.

The compiled binary (named gnirehtet) will be located in the same directory where the script is executed.

gnirehtet android app

gnirehtet app would work on most devices so you don't need to build it yourself. The apk file in this repository is from official gnirehtet release.

To build the Android app: gnirehtet/DEVELOP.md
