iOS Hotspot Proxy

Cellular traffic proxy for ad hoc network on iOS. No jailbreak. Need Python for iOS.

In A Nutshell

When iOS device connects to ad hoc network (Mac computer-to-computer network), it can still access the internet via device's 2G/3G/4G channel. Your laptop is connected to the iOS device, and your iOS device is connected to the internet. Ta-da! Your laptop is connected to internet!

How It Works

Python 2.7 for iOS can run python scripts! With common libraries! A simple multithreading with socket programming does the trick. The Python script listens to the ad hoc network and acts as a proxy. When receiving the request from laptop, it connects to a remote proxy and bidirectionally forwords the traffic.

Prerequisite

• Download the Python 2.7 for iOS
• Run your proxy and make it public
• Modify PROXYHOST, PROXYPORT in proxy.py with you public proxy info
• Copy the script to Python 2.7 for iOS

Do the Magic

• Create ad hoc network from your laptop
• Connect your iOS device to your laptop
• Assign two different IP for these two devices
• Set appropriate subnet mask, of course
• Leave the router address empty on iOS device
• Ping your iOS device from you laptop, it should work
• Change your laptop global http/https proxy configuration, use the iOS device IP and proxy port, default 50007
• Open your browser and enjoy

TODO

Pipe the socket or implement the actual proxy

What I Want to Say

• Better than the single thread websocket solution.
• Python multiprocessing lib doesn't work well in that app
• I use appshopper.com to watch that app's price. Half year's waiting and missed $0.99 deal on Apr 16 '13
• Adium needs to use global http/https proxy setting
• Use your finger to keep the screen active
• It can warm your heart when proxying
• Sprint 3G network sucks! Especially for my 4s
