## Features



This project is a client library to multiplex connections from and to iOS

devices alongside command-line utilities.



It is primarily used by applications which use the [libimobiledevice](https://github.com/libimobiledevice/)

library to communicate with services running on iOS devices.



The library does not establish a direct connection with a device but requires

connecting to a socket provided by the usbmuxd daemon.



The usbmuxd daemon is running upon installing iTunes on Windows and Mac OS X.



The [libimobiledevice project](https://github.com/libimobiledevice/) provides an open-source reimplementation of

the [usbmuxd daemon](https://github.com/libimobiledevice/usbmuxd.git/) to use on Linux or as an alternative to communicate with

iOS devices without the need to install iTunes.



Some key features are:



- **Protocol:** Provides an interface to handle the usbmux protocol

- **Port Proxy:** Provides the `iproxy` utility to proxy ports to the device

- **Netcat:** Provides the `inetcat` utility to expose a raw connection to the device

- **Cross-Platform:** Tested on Linux, macOS, Windows and Android platforms

- **Flexible:** Allows using the open-source or proprietary usbmuxd daemon



Furthermore the Linux build optionally provides support using inotify if

available.



## Building



### Prerequisites



You need to have a working compiler (gcc/clang) and development environent

available. This project uses autotools for the build process, allowing to

have common build steps across different platforms.

Only the prerequisites differ and they are described in this section.



libusbmuxd requires [libplist](https://github.com/libimobiledevice/libplist) and [libimobiledevice-glue](https://github.com/libimobiledevice/libimobiledevice-glue). On Linux, it also requires [usbmuxd](https://github.com/libimobiledevice/usbmuxd) installed on the system, while macOS has its own copy and on Windows AppleMobileDeviceSupport package provides it.

Check [libplist's Building](https://github.com/libimobiledevice/libplist?tab=readme-ov-file#building) and [libimobiledevice-glue's Building](https://github.com/libimobiledevice/libimobiledevice-glue?tab=readme-ov-file#building)

section of the respective README on how to build them. Note that some platforms might have them as a package.



#### Linux (Debian/Ubuntu based)



* Install all required dependencies and build tools:

  ```shell

  sudo apt-get install \

  	build-essential \

  	pkg-config \

  	checkinstall \

  	git \

  	autoconf \

  	automake \

  	libtool-bin \

  	libplist-dev \

  	libimobiledevice-glue-dev \

  	usbmuxd

  ```

  In case libplist-dev, libimobiledevice-glue-dev, or usbmuxd are not available, you can manually build and install them. See note above.



#### macOS



* Make sure the Xcode command line tools are installed. Then, use either [MacPorts](https://www.macports.org/)

  or [Homebrew](https://brew.sh/) to install `automake`, `autoconf`, `libtool`, etc.



  Using MacPorts:

  ```shell

  sudo port install libtool autoconf automake pkgconfig

  ```



  Using Homebrew:

  ```shell

  brew install libtool autoconf automake pkg-config

  ```



#### Windows



* Using [MSYS2](https://www.msys2.org/) is the official way of compiling this project on Windows. Download the MSYS2 installer

  and follow the installation steps.



  It is recommended to use the _MSYS2 MinGW 64-bit_ shell. Run it and make sure the required dependencies are installed:



  ```shell

  pacman -S base-devel \

  	git \

  	mingw-w64-x86_64-gcc \

  	make \

  	libtool \

  	autoconf \

  	automake-wrapper \

  	pkg-config

  ```

  NOTE: You can use a different shell and different compiler according to your needs. Adapt the above command accordingly.



### Configuring the source tree



You can build the source code from a git checkout, or from a `.tar.bz2` release tarball from [Releases](https://github.com/libimobiledevice/libusbmuxd/releases).

Before we can build it, the source tree has to be configured for building. The steps depend on where you got the source from.



Since libusbmuxd depends on other packages, you should set the pkg-config environment variable `PKG_CONFIG_PATH`

accordingly. Make sure to use a path with the same prefix as the dependencies. If they are installed in `/usr/local` you would do



```shell

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

```



* **From git**



  If you haven't done already, clone the actual project repository and change into the directory.

  ```shell

  git clone https://github.com/libimobiledevice/libusbmuxd

  cd libusbmuxd

  ```



  Configure the source tree for building:

  ```shell

  ./autogen.sh

  ```



* **From release tarball (.tar.bz2)**



  When using an official [release tarball](https://github.com/libimobiledevice/libusbmuxd/releases) (`libusbmuxd-x.y.z.tar.bz2`)

  the procedure is slightly different.



  Extract the tarball:

  ```shell

  tar xjf libusbmuxd-x.y.z.tar.bz2

  cd libusbmuxd-x.y.z

  ```



  Configure the source tree for building:

  ```shell

  ./configure

  ```



Both `./configure` and `./autogen.sh` (which generates and calls `configure`) accept a few options, for example `--prefix` to allow

building for a different target folder. You can simply pass them like this:



```shell

./autogen.sh --prefix=/usr/local

```

or

```shell

./configure --prefix=/usr/local

```



Once the command is successful, the last few lines of output will look like this:

```

[...]

config.status: creating config.h

config.status: executing depfiles commands

config.status: executing libtool commands



Configuration for libusbmuxd 2.1.0:

-------------------------------------------



  Install prefix: .........: /usr/local

  inotify support (Linux) .: no



  Now type 'make' to build libusbmuxd 2.1.0,

  and then 'make install' for installation.

```



## Usage



### iproxy



This utility allows binding local TCP ports so that a connection to one (or

more) of the local ports will be forwarded to the specified port (or ports) on

a usbmux device.



Bind local TCP port 2222 and forward to port 22 of the first device connected

via USB:

```shell

iproxy 2222:22

```



This would allow using ssh with `localhost:2222` to connect to the sshd daemon

on the device. Please mind that this is just an example and the sshd daemon is

only available for jailbroken devices that actually have it installed.



Please consult the usage information or manual page for a full documentation of

available command line options:

```shell

iproxy --help

man iproxy

```



### inetcat



This utility is a simple netcat-like tool that allows opening a read/write

interface to a TCP port on a usbmux device and expose it via STDIN/STDOUT.



Use ssh ProxyCommand to connect to a jailbroken iOS device via SSH:

```shell

ssh -oProxyCommand="inetcat 22" root@localhost

```



Please consult the usage information or manual page for a full documentation of

available command line options:

```shell

inetcat --help

man inetcat

```



### Environment



The environment variable `USBMUXD_SOCKET_ADDRESS` allows to change the location

of the usbmuxd socket away from the local default one.



An example of using an utility from the libimobiledevice project with an usbmuxd

socket exposed on a port of a remote host:

```shell

export USBMUXD_SOCKET_ADDRESS=192.168.179.1:27015

ideviceinfo

```



This sets the usbmuxd socket address to `192.168.179.1:27015` for applications

that use the libusbmuxd library.
