A client library for applications to handle usbmux protocol connections with iOS devices.
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:
iproxy utility to proxy ports to the deviceinetcat utility to expose a raw connection to the deviceFurthermore the Linux build optionally provides support using inotify if available.
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 and libimobiledevice-glue. On Linux, it also requires usbmuxd installed on the system, while macOS has its own copy and on Windows AppleMobileDeviceSupport package provides it. Check libplist's Building and libimobiledevice-glue's Building section of the respective README on how to build them. Note that some platforms might have them as a package.
sudo apt-get install \ build-essential \ pkg-config \ checkinstall \ git \ autoconf \ automake \ libtool-bin \ libplist-dev \ libimobiledevice-glue-dev \ usbmuxdIn case libplist-dev, libimobiledevice-glue-dev, or usbmuxd are not available, you can manually build and install them. See note above.
Make sure the Xcode command line tools are installed. Then, use either MacPorts or Homebrew to install automake, autoconf, libtool, etc.
Using MacPorts:
sudo port install libtool autoconf automake pkgconfig
Using Homebrew:
brew install libtool autoconf automake pkg-config
Using MSYS2 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:
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.
You can build the source code from a git checkout, or from a .tar.bz2 release tarball from 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
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.
git clone https://github.com/libimobiledevice/libusbmuxd cd libusbmuxd
Configure the source tree for building:
./autogen.sh
From release tarball (.tar.bz2)
When using an official release tarball (libusbmuxd-x.y.z.tar.bz2) the procedure is slightly different.
Extract the tarball:
tar xjf libusbmuxd-x.y.z.tar.bz2 cd libusbmuxd-x.y.z
Configure the source tree for building:
./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:
./autogen.sh --prefix=/usr/local
or
./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.
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
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
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.
