Lokinet

Español Русский

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

And you can read the LLARP protocol specification here

You can view documentation on how to get started here .

A simple demo application that is lokinet "aware" can be found here

Installing

If you are simply looking to install Lokinet and don't want to compile it yourself the Oxen Docs Lokinet Guides for gentler instructions to get up and running.

Building

Build requirements:

• Git
• 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

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.

You can install these 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
$ 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

Cross Compile

supported cross targets:

• aarch64
• armhf
• mips
• mips64
• mipsel
• ppc64le

install the toolchain for $arch this example is aarch64

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

build 1 or many cross targets:

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

macOS

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 for more information. If you find this disagreeable consider using a platform that permits compiling from source.

Windows

You can get the latest stable windows release from https://lokinet.org/ or check the releases page on github.

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

building:

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

FreeBSD

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

Usage

Debian / Ubuntu packages

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)

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
