The built-in toolbox tools in the Android system (under /system/bin) are too simple, and poorly supports some very useful Unix/Linux commands, such as find.

Unfortunately, all characteristics of Shadowsocks (SS) and ShadowsocksR (SSR) have been fully and absolutely identified and controlled by GFW ("thanks to" the forced compromise from their developers). In short, as long as the GFW wants to block your VPS, it can now do this easily and perfectly in less than 30 seconds. If you find that your SS/SSR is still working well, that means GFW has no interest or there is no need to ban you right now. Of course, each blocking cycle of GFW is about 10 weeks. Therefore, we can roughly calculate when our VPS can be unblocked.

OGRE (short for Object-Oriented Graphics Rendering Engine) is a free, open-source, and cross-platform 3D graphics real-time rendering engine that is widely used in 3D simulation and game development fields, written in C++ in 2001.
