# 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](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. - **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 ### Debian / Ubuntu Linux First install all required dependencies and build tools: ```shell sudo apt-get install \ build-essential \ checkinstall \ git \ autoconf \ automake \ libtool-bin \ libplist-dev ``` Then clone the actual project repository: ```shell git clone https://github.com/libimobiledevice/libusbmuxd.git cd libusbmuxd ``` Now you can build and install it: ```shell ./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: ```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. ## Links * Homepage: https://libimobiledevice.org/ * Repository: https://git.libimobiledevice.org/libusbmuxd.git * Repository (Mirror): https://github.com/libimobiledevice/libusbmuxd.git * Issue Tracker: https://github.com/libimobiledevice/libusbmuxd/issues * Mailing List: https://lists.libimobiledevice.org/mailman/listinfo/libimobiledevice-devel * Twitter: https://twitter.com/libimobiledev ## License This library is licensed under the [GNU Lesser General Public License v2.1](https://www.gnu.org/licenses/lgpl-2.1.en.html), also included in the repository in the `COPYING` file.
