Cannot run iOS Simulator is proxychains #104

Open minimedj opened 8 years ago

minimedj commented 8 years ago

I cannot run iOS Simulator with proxychains-ng. I use proxychains-ng build from sources.

Here is what I did:

git clone https://github.com/rofl0r/proxychains-ng.git
cd ./proxychains-ng
./configure --prefix=/usr --sysconfdir=/etc --fat-binary
make
sudo make install

I checked architecture of the library:

lipo -info ./libproxychains4.dylib 
Architectures in the fat file: ./libproxychains4.dylib are: i386 x86_64

Then I configured and checked SOCKS proxy:

./proxychains4 -f src/proxychains.conf curl ipinfo.io
[proxychains] config file found: src/proxychains.conf
[proxychains] preloading ./libproxychains4.dylib
[proxychains] DLL init: proxychains-ng 4.10-git-20-g672bf76
[proxychains] Strict chain  ...  127.0.0.1:8888  ...  ipinfo.io:80  ...  OK
...

So far everything seems to be just fine. Now about the problem. When I tty to run iOS Simulator I get an error. Here is a command I use to run Simulator:

./proxychains4 -f src/proxychains.conf /Applications/Xcode.app/Contents/Developer/Applications/Simulator.app/Contents/MacOS/Simulator

Here is the error:

Any ideas how to fix it?

proxychains hooks posix socket API. However iOS(and simulator as well) doesn't use posix API to access network. NS-related network API are actually handled by a daemon called networkd which implements TCP from scratch to support MPTCP.

@Qusic thank you very much for detailed answer!

So, is it possible to proxy iOS Simulator somehow? :open_mouth:
