# ZeroTier for Magisk [[中文](https://github.com/eventlOwOp/zerotier-magisk/blob/master/README_ZH.md) | English]

**Run zerotier in the background after booting!** **No conflicts with other Android VPN service!** **Use Android App to control ZeroTier** **Support for Private Root Servers** ## Requirements 1. a version is built with Android NDK Toolchain, supporting api 28 (Android 9.0) and above. 2. another version is build with GCC toolchain, linking to Linux Syscalls statically Unofficial planet supported; SSO (zeroidc) supported in the version built with GCC for AArch64 AArch64 suppots ARMv8-A and above; Arm version supports ARMv7-A (compiling with `-march=armv7-a`) ## Installation 1. Download magisk module zip file from github release; install. 2. Download controller app apk file from github release; install. 3. Reboot your phone. 4. Open controller app; enter your 16-character network id; join. 5. Enjoy 😋 ## Usage ### Use Private Root Servers Replace `/data/adb/zerotier/home/planet` with your own `planet` file. ### Controller App Does not need root privilege | Feature | Supported? | | :----------------- | :--------- | | status | ✅ | | start/stop | ✅ | | join/leave network | ✅ | | join/leave planet | ❎ |

### Command line tools Use `zerotier.sh` to start/stop or inspect status. `Usage: zerotier.sh {start|stop|restart|status}` Use `zerotier-cli / zerotier-idtool` for ZeroTierOne command line operations. (`zerotier-one` not copied to `/system/bin`) ## Files ``` /data/adb/zerotier ├── home # zerotier-one home directory │ ├── authtoken.secret # zerotier-one http interface authtoken │ ├── zerotier-one.pid # zerotier-one pid │ ├── zerotier-one.port # zerotier-one port │ └── ... ├── lib # only in NDK compiled module │ └── libc++_shared.so # NDK dynamic library ├── run │ ├── daemon.log # service.sh log │ ├── pipe # named pipe to interact with service.sh │ ├── zerotier.log # zerotier-one log │ └── ... ├── zerotier-cli -> zerotier-one # zerotier-one command line interface ├── zerotier-idtool -> zerotier-one # zerotier-one id tool ├── zerotier-one # zerotier-one executable └── zerotier.sh ``` all the scripts and binaries are placed in `/data/adb/zerotier/`, and all copied to `/system/bin` (in PATH) to be executed directly (except `zerotier-one`) `zerotier.sh` uses named pipe to communicate with `service.sh`, preventing ZeroTier to start as a subprocess of Shell. log files are placed in `run`, `daemon.log` for `service.sh` and `zerotier.log` for ZeroTierOne. ## Build binaries yourself refer to `.github/workflow/build-{gcc|ndk}.yml` for detailed information. ## Notes After 1.14.0, ZeroTierOne has introduce `multi-core concurrent packet processing`, which requires `pthread_setaffinity_np`. However, for NDK, `pthread_setaffinity_np` won't be available until API level 36, Android 16. (refer to https://android.googlesource.com/platform/bionic/+/master/libc/include/pthread.h) So in the NDK bulid version, it is replaced by the combination of `pthread_gettid_np` from `` and `sched_getaffinity` from ``.
