A client library to multiplex connections from and to iOS devices

libusbmuxd

A client library for applications to handle usbmux protocol connections with iOS devices.

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 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 provides an open-source reimplementation of the usbmuxd daemon 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.

Installation / Getting started

Project dependcies:

• libplist
• libimobiledevice-glue

Windows

First install MSYS2.

Then open MSYS2 MINGW32 (or MSYS2 MINGW64 if your want to build for x64).

Install all required dependencies and build tools

# for x86
pacman -S mingw-w64-i686-toolchain 
pacman -S --needed base-devel msys2-devel
pacman -S git mingw-w64-i686-cython0 mingw-w64-i686-libzip
pacman -S make automake autoconf libtool pkgconf openssl openssl-devel

Then clone the actual project repository:

git clone https://github.com/liungkejin/libusbmuxd.git
cd libusbmuxd

Now you can build and install it:

./autogen.sh
make
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:

./autogen.sh --prefix=/opt/local
make
make install

You can find the dll file in %MSYS2 INSTALL PATH%\mingw32\bin If you want use this dll in Visual Studio C++ Project, you need use pexports.exe to generate .lib file

pexports.exe -v libxxx.dll > libxxx.def

Then open x86 Native Tools Command Prompt or x64 Native Tools Command Prompt

run

lib /DEF:libxxx.def

Then you can use this libxxx.lib file in C++ project

#pragma comment(lib, "libxxx.lib")

Debian / Ubuntu Linux

First install all required dependencies and build tools:

sudo apt-get install \
	build-essential \
	pkg-config \
	checkinstall \
	git \
	autoconf \
	automake \
	libtool-bin \
	libplist-dev \
	libimobiledevice-glue-dev \
	usbmuxd

Then clone the actual project repository:

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

Now you can build and install it:

./autogen.sh
make
sudo make install

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:

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:

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:

ssh -oProxyCommand="inetcat 22" root@localhost

Please consult the usage information or manual page for a full documentation of available command line options:

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:

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.
