Debugging

How to enable log?

First, set build as DEBUG. This will define DEBUG macro variable by Xcode.

Go to Product-> Scheme-> Edit Scheme -> Run Tethering.app -> Build configuration. Change setting to DEBUG

Secondly, if you use NSLOG, modify SocksProxy_Prefix.pch and undefine the macro USE_NSLOGGER_LIB. If you want to use NSLogger, define USE_NSLOGGER_LIB.

Clone repo from NSLogger and build its Mac GUI to explore log.

How to debug by external tools?

Any network packet sniffer in your PC/Mac should work. You can take a deep look in SOCKS handshake, DNS packet and etc. Personally, I prefer to use Wireshark in Mac OS X and Linux.
