# usbmuxd
*A socket daemon to multiplex connections from and to iOS devices.*
## Features
usbmuxd stands for "USB multiplexing daemon". This daemon is in charge of
multiplexing connections over USB to an iOS device.
To users, it means you can use various applications to interact with your
device.
To developers, it means you can connect to any listening localhost socket on
the device.
Some key features are:
- **Implementation**: Open-Source implementation of proprietary usbmuxd daemon
- **Cross-Platform:** Tested on Linux, macOS, Windows and Android platforms
- **Linux**: Supports udev and systemd for automatic activation
- **Compatibility**: Supports latest device firmware releases
- **Scalability**: Supports multiple connections to different ports in parallel
usbmuxd is not used for tethering data transfers which uses a dedicated USB
interface to act as a virtual network device.
The higher-level layers, especially if you want to write an application to
interact with the device, are handled by [libimobiledevice](https://github.com/libimobiledevice/libimobiledevice.git).
The low-level layer is handled by [libusbmuxd](https://github.com/libimobiledevice/libusbmuxd.git).
## Installation / Getting started
### Debian / Ubuntu Linux
First install all required dependencies and build tools:
```shell
sudo apt-get install \
build-essential \
pkg-config \
checkinstall \
git \
autoconf \
automake \
libtool-bin \
libplist-dev \
libusbmuxd-dev \
libimobiledevice-dev \
libimobiledevice-glue-dev \
libusb-1.0-0-dev \
udev
```
If systemd is not installed and should control spawning the daemon use:
```shell
sudo apt-get install \
systemd
```
Then clone the actual project repository:
```shell
git clone https://github.com/libimobiledevice/usbmuxd.git
cd usbmuxd
```
Now you can build and install it:
```shell
./autogen.sh
make
sudo make install
```
If you require a custom prefix or other option being passed to `./configure`
you can pass them directly to `./autogen.sh` like this:
```bash
./autogen.sh --prefix=/opt/local --without-preflight --without-systemd
make
sudo make install
```
To output a list of available configure options use:
```bash
./autogen.sh --help
```
## Usage
The daemon is automatically started by udev or systemd depending on what you
have configured upon hotplug of an iOS device and exits if the last device
was unplugged.
When usbmuxd is running it provides a socket interface at `/var/run/usbmuxd`
that is designed to be compatible with the socket interface that is provided
on macOS.
You should also create an `usbmux` user that has access to USB devices on your
system. Alternatively, just pass a different username using the `-U` argument.
The daemon also manages pairing records with iOS devices and the host in
`/var/lib/lockdown` (Linux) or `/var/db/lockdown` (macOS).
Ensure proper permissions are setup for the daemon to access the directory.
For debugging purposes it is helpful to start usbmuxd using the foreground `-f`
argument and enable verbose mode `-v` to get suitable logs.
Please consult the usage information or manual page for a full documentation of
available command line options:
```shell
usbmuxd --help
man usbmuxd
```
## Contributing
We welcome contributions from anyone and are grateful for every pull request!
If you'd like to contribute, please fork the `master` branch, change, commit and
send a pull request for review. Once approved it can be merged into the main
code base.
If you plan to contribute larger changes or a major refactoring, please create a
ticket first to discuss the idea upfront to ensure less effort for everyone.
Please make sure your contribution adheres to:
* Try to follow the code style of the project
* Commit messages should describe the change well without being too short
* Try to split larger changes into individual commits of a common domain
* Use your real name and a valid email address for your commits
We are still working on the guidelines so bear with us!
