A socket daemon to multiplex connections from and to iOS devices.
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 sync your music, contacts, photos, etc. over USB. To developers, it means you can connect to any listening localhost socket on the device. usbmuxd is not used for tethering data transfer which uses a dedicated USB interface as a virtual network device. Multiple connections to different TCP ports can happen in parallel. The higher-level layers are handled by libimobiledevice.
When usbmuxd is running (normally started or stopped as a result of udev
auto-insertion messages, or by systemd) it provides a socket interface in
/var/run/usbmuxd that is designed to be compatible with the socket interface
that is provided on macOS.
You should also create a usbmux user that has access to USB devices on your
system. Alternatively, you can 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.
Development Packages of:
- libimobiledevice
- libplist
- libusb
Software:
- make
- autoheader
- automake
- autoconf
- libtool
- pkg-config
- gcc or clang
- udev (Linux only)
Optional:
- systemd (Linux only)
To compile run:
./autogen.sh
make
sudo make installThe daemon is automatically started by udev or systemd depending on what you have configured it on hotplug of an iOS device and exits if the last device was unplugged.
For debugging purposes it is helpful to start usbmuxd using the foreground -f
argument and enable verbose mode -v to get suitable logs.
