Husarnet Client

Husarnet is a Peer-to-Peer VPN to connect your laptops, servers and microcontrollers over the Internet with zero configuration.

Key features:

  • Low Latency - thanks to Peer-to-Peer connection between devices. After establishing a connection, Husarnet Infrastructure (Husarnet Base Servers) is used only as a failover proxy if P2P connection is not possible.
  • Zero Configuration - after installing Husarnet Client, you can add new devices to your network with a single command husarnet join <YOUR_JOINCODE> mydevname (on Linux. See docs for other platforms).
  • Low Reconfiguration Time - in case of a network topology change (eg. transition between two Wi-Fi hotspots), Husarnet needs usually 1 - 3 seconds to reastablish a new Peer-to-Peer connection.
  • Lightweight - it works not only on popular OSes (currently only Linux version is released, Windows, MacOS, Android coming soon) but even on ESP32 microcontrollers. That means you can P2P access your things without IoT server at all!
  • Secure & Private - packets never leave connected devices unencrypted, Perfect Forward Secrecy (PFC) enabled by default.

Husarnet, in it's core, is one big, automatically routed, IPv6 network. Running Husarnet daemon creates a virtual network interface (hnet0) with an unique Husarnet IPv6 address and associated fc94::/16 route. If you choose to disable the permission system, any node can reach your node using IPv6 fc94:... address, but if you choose to leave it enabled, we've prepared an extensive permissions system for you. You can have multiple virtual islands/networks, your devices can access multiple networks or you can even share access to those networks with other users!

The nodes are identified by their 112-bit IPv6 addresses, that are based on the public keys of the node. All connections are also authenticated by the IPv6 address. This property makes it possible to establish connection authenticity without any trusted third party, basing only on the IPv6 address! The connections are also always encrypted.

Cryptography: Husarnet uses X25519 from libsodium for key exchange, with ephemeral Curve25519 keys for forward secrecy. The hash of initial public key is validated to match the IPv6 address. The packets are encrypted using libsodium's ChaCha20-Poly1305 secretbox construction with a random 192-bit nonce.

Runtime safety: Husarnet is written in C++ using modern memory-safe constructs. Linux version drops all capabilities after initialization. It only retains access to /etc/hosts and /etc/hostname via a helper process.

If Husarnet instance is not connected to the Husarnet Dashboard, the whitelist (think of it as a crude firewall) and hostname table can only be changed by a local root user. All the other configuration can be changed using the Husarnet Dashboard after you join your device to a network there.

This is the main development repository for all of the Husarnet Client apps.

For more generic information please have a look at the Husarnet Docs.

Typical issues preventing Peer-to-Peer connection (thus enjoing a low-latency) and their workarounds are described in the Troubleshooting Guide.

Repository organization

  • util directory - all the scripts and utilities used for building and testing. CI config should be referencing those in order to make local testing easier
  • unix directory - main dir for unix platform code
  • tests directory - unit (and other) tests (unit tests will run on x86_64 unix platform)
  • deploy directory - various files needed for deployment - like the static files in our repositories

Building and publishing

  • ./util/build-prepare.sh - will install all required toolchains, etc - tested on Ubuntu 20.10
  • If you want to bump the current version (i.e. as a preparation for release) - ./util/version-bump.py (keep in mind that all merges/commits to the default branch will to that automatically)
  • If you want to build:
    • all platforms: ./util/build-all.sh
    • specific platform:
      • platforms using cmake: ./util/build-cmake.sh <architecture> <platform>
  • CI will be doing these steps automatically when ran on default branch:
    • bump and commit the new version "number"
    • build for all platforms and architectures (when available)
    • test all platforms and architectures (when available)
    • publish to the internal repositories
    • wait for manual confirmation to publish in the public repo
  • CI will be doing these steps then ran on any other branch:
    • build for all platforms and architectures (when available)
    • test all platforms and architectures (when available)

Running tests

  • ./util/test-prepare.sh - will install required tools
  • ./util/test-all.sh - will run ALL tests
  • ./util/test-cppcheck.sh - will run cppcheck
  • ./util/test-unit.sh - will build and run unit tests. Assumes host machine is x86 and runs some form of Unix

CI extra notes

  • ./util/prepare-all.sh - this will prepare both build and test environments

  • High latency when 2 devices are not in local network

    High latency when 2 devices are not in local network

    Hi,

    When the connection is P2P, it has low latency. But when they are not in local network (eg. I connect to my phone mobile hotspot), the connection is tunelled and it has very high latency. Is it that husarnet cannot work with mobile hotspot? Is there any solutions for that?

    Thank you.

    husarnet-ros no installation candidate

    HI, Recently, I tried the tutorials for using husarnet & ros

    From there, I tried to install husarnet-ros

    Getting this error

    sudo apt-get install husarnet-ros
Reading package lists... Done
Building dependency tree

Package husarnet-ros is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or

E: Package 'husarnet-ros' has no installation candidate

    Can you please help with this? Thank you :)

    Ubuntu 20.10 has reached EOL

    I noticed the Dockerfiles of the samples are using Ubuntu 20.10, but they are already end-of-life. All apt commands return an error, when I fetch it.

    Is there any issue in upgrading them to 21.04? Why the LTS release isn't being used instead?

    Hi there. I am trying to use the join code command husarnet join <your-join-code> <device-hostname> provided in the installation guide. Apparently it keeps on repeating the "joining" message as shown below,

    In the web app I am not able to see the device joining into the network. I have checked the ufw status and get these results and I believe that the ports are enabled by default by Husarnet.

    May I know are there any ways that I can troubleshoot this issue? Is it because of blocked UDP or I have missed out on any installation steps? I have followed the installation guide based on this link https://husarnet.com/docs/tutorial-ros2/#ros-2-and-dds-implementation. Appreciate any suggestions or advice. Thank you.

  • Multimaster usage

    Multimaster usage

    Hello !!

    I have an application where I will deploy a fleet of mobile robots but I would need them to be auto-sufficient, so it would be best that every robot has its own master, regardless of connectivity with the internet.

    For that purpose we setup the " fkie multimaster" package so that the robots can exchange some information when connected. For the multimaster to work correctly we need to be able to ping a broadcast address (224.0.0.1) through the husarnet interface.

    Is that possible? If I'm not mistaken using broadcast needs the interface to be a tap interface which will relay also layer 2 data.

    It is possible to achieve that?

    Thanks in advance!

    Hi,

    Microsoft now has its own package manager, similar to apt in a Linux environment. Can we please have husarnet added to it so that people can install and upgrade the client more easily.

    Thanks, dRm

    Status on MacOS?

    Hello,

    Switching to Mac has been quite painful since there's no Mac client available. Is there an ETA for when MacOS client will arrive? If it matters, ARM architecture is relevant for me.
