# Lokinet

[Español](readme_es.md) [Русский](readme_ru.md)

Lokinet is the reference implementation of LLARP (low latency anonymous routing protocol), a layer 3 onion routing protocol.

You can learn more about the high level design of LLARP [here](docs/)

[![Build Status](https://ci.oxen.rocks/api/badges/oxen-io/lokinet/status.svg?ref=refs/heads/dev)](https://ci.oxen.rocks/oxen-io/lokinet)

* CMake
* C++ 17 capable C++ compiler
* libuv >= 1.27.0
* libsodium >= 1.0.18
* libssl (for lokinet-bootstrap)
* libcurl (for lokinet-bootstrap)
* libunbound
* libzmq
* cppzmq
* sqlite3

### Linux <span id="linux-install" />

You do not have to build from source if you are on debian or ubuntu as we have apt repositories with pre-built lokinet packages on `deb.oxen.io` or `rpm.oxen.io`.

You can install debian packages using:

    $ sudo curl -so /etc/apt/trusted.gpg.d/oxen.gpg https://deb.oxen.io/pub.gpg
    $ echo "deb https://deb.oxen.io $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/oxen.list
    $ sudo apt update
    $ sudo apt install lokinet


If you want to build from source:

    $ sudo apt install build-essential cmake git libcap-dev pkg-config automake libtool libuv1-dev libsodium-dev libzmq3-dev libcurl4-openssl-dev libevent-dev nettle-dev libunbound-dev libsqlite3-dev libssl-dev nlohmann-json3-dev
    $ git clone --recursive https://github.com/oxen-io/lokinet
    $ cd lokinet
    $ mkdir build
    $ cd build
    $ cmake .. -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=OFF
    $ make -j$(nproc)
    $ sudo make install

#### Arch Linux <span id="mom-cancel-my-meetings-arch-linux-broke-again" />

Due to [circumstances beyond our control](https://github.com/oxen-io/lokinet/discussions/1823) a working `PKGBUILD` can be found [here](https://raw.githubusercontent.com/oxen-io/lokinet/makepkg/contrib/archlinux/PKGBUILD).

#### Cross Compile For Linux <span id="linux-cross" />

current cross targets:

* aarch64-linux-gnu
* arm-linux-gnueabihf
* mips-linux-gnu
* mips64-linux-gnuabi64
* mipsel-linux-gnu
* powerpc64le-linux-gnu

install the toolchain (this one is for `aarch64-linux-gnu`, you can provide your own toolchain if you want)

    $ sudo apt install g{cc,++}-aarch64-linux-gnu

build 1 or many cross targets:

    $ ./contrib/cross.sh arch_1 arch_2 ... arch_n

### MacOS <span id="mac-install" />

Lokinet ~~is~~ will be available on the Apple App store.

Source code compilation of Lokinet by end users is not supported or permitted by apple on their platforms, see [this](contrib/macos/README.txt) for more information. If you find this disagreeable consider using a platform that permits compiling from source.

### Windows <span id="windows-install" />

You can get the latest stable windows release from https://lokinet.org/ or check the [releases page on github](https://github.com/oxen-io/lokinet/releases).

nightly builds for the brave or impatient can be found from our CI pipeline [here](https://oxen.rocks/oxen-io/lokinet/)

#### Building For Windows <span id="win32-cross" />

windows builds are cross compiled from debian/ubuntu linux

additional build requirements:

* nsis
* cpack

setup:

    $ sudo apt install build-essential cmake git pkg-config mingw-w64 nsis cpack automake libtool
    $ sudo update-alternatives --set x86_64-w64-mingw32-gcc /usr/bin/x86_64-w64-mingw32-gcc-posix
    $ sudo update-alternatives --set x86_64-w64-mingw32-g++ /usr/bin/x86_64-w64-mingw32-g++-posix

building:

    $ git clone --recursive https://github.com/oxen-io/lokinet
    $ cd lokinet
    $ ./contrib/windows.sh

### FreeBSD <span id="freebsd-install" />

Currently has no VPN Platform code, see #1513

build:

    $ pkg install cmake git pkgconf
    $ git clone --recursive https://github.com/oxen-io/lokinet
    $ cd lokinet
    $ mkdir build
    $ cd build
    $ cmake -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=OFF -DSTATIC_LINK=ON -DBUILD_STATIC_DEPS=ON ..
    $ make

install (root):

    # make install
    
### Android <span id="apk-install" />

We have an Android APK for lokinet VPN via android VPN API. 

Coming to F-Droid whenever that happens. [[issue]](https://github.com/oxen-io/lokinet-flutter-app/issues/8)

* [source code](https://github.com/oxen-io/lokinet-flutter-app)
* [CI builds](https://oxen.rocks/oxen-io/lokinet/)

## Usage

### Debian / Ubuntu packages <span id="systemd-linux-usage" />

When running from debian package the following steps are not needed as it is already running and
ready to use.  You can stop/start/restart it using `systemctl start lokinet`, `systemctl stop
lokinet`, etc.

### Running on Linux (without debs) <span id="arcane-linux-usage" />

**DO NOT RUN AS ROOT**, run as normal user.

set up the initial configs:

    $ lokinet -g
    $ lokinet-bootstrap

after you create default config, run it:

    $ lokinet

This requires the binary to have the proper capabilities which is usually set by `make install` on the binary. If you have errors regarding permissions to open a new interface this can be resolved using:

    $ sudo setcap cap_net_admin,cap_net_bind_service=+eip /usr/local/bin/lokinet
