iproxy

An example tool to forward localhost ports to iOS devices

'usbmuxd' stands for "USB multiplexing daemon". This daemon is in charge of multiplexing connections over USB to an iPhone or iPod touch. 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. An example (and useful) tool called 'iproxy' is included that allows you to forward localhost ports to the device---allows SSH over USB on jailbroken devices, or allowing access the lockdown daemon (and then to all of the file access, sync, notification and backup services running on the device).
