This project provides reverse tethering over
adb for Android: it
allows devices to use the internet connection of the computer they are plugged
on. It does not require any root access (neither on the device nor on the
computer). It works on GNU/Linux, Windows and Mac OS.
Two implementations of Gnirehtet are available:
- one in Java;
- one in Rust.
Which one to choose?
Use the Rust implementation. The native binary consumes less CPU and memory, and does not require a Java runtime environment.
The relay server of Gnirehtet was initially only implemented in Java. As a benefit, the same "binary" runs on every platform having Java 8 runtime installed. It is still maintained to provide a working alternative in case of problems with the Rust version.
The Android application requires at least API 21 (Android 5.0).
For the Java version only, Java 8 (JRE) is required on your computer. On
Debian-based distros, install the package
You need a recent version of adb (where
adb reverse is implemented, it
works with 1.0.36).
It is available in the Android SDK platform tools.
On Debian-based distros, you can alternatively install the package
On Windows, if you need
adb only for this application, just download the
platform-tools and extract the following files to the
Make sure you enabled adb debugging on your device(s).
Download the latest release in the flavor you want.
Then extract it.
The Linux and MacOS archives contain:
The Windows archive contains:

Then extract it. The archive contains:

The application has no UI, and is intended to be controlled from the computer only.
If you want to activate reverse tethering for exactly one device, just execute:
Reverse tethering remains active until you press Ctrl+C.
On Windows, for convenience, you can double-click on
instead (it just executes

The very first start should open a popup to request permission:
A "key" logo appears in the status bar whenever Gnirehtet is active:
You can execute the actions separately (it may be useful if you want to reverse tether several devices simultaneously).
Start the relay server and keep it open:
apk on your Android device:
./gnirehtet install [serial]
(if an older version of gnirehtet was already installed, you must install the new one first)
In another terminal, for each client, execute:
./gnirehtet start [serial]
To stop a client:
./gnirehtet stop [serial]
The serial parameter is required only if
adb devices outputs more than one
For advanced options, call
./gnirehtet without arguments to get more details.
gnirehtet program exposes a simple command-line interface that executes
lower-level commands. You can call them manually instead.
To start the relay server:
java -jar gnirehtet.jar relay
To install the apk:
adb install -r gnirehtet.apk
To start a client:
adb reverse tcp:31416 tcp:31416 adb shell am startservice -a com.genymobile.gnirehtet.START
To stop a client:
adb shell am startservice -a com.genymobile.gnirehtet.STOP
