easy-novnc

An easy way to run a noVNC instance and proxy with a single binary.

Features

  • Clean start page.
  • CIDR whitelist/blacklist.
  • Optionally allow connections to arbitrary hosts (and ports).
  • Ensures the target port is a VNC server to prevent tunneling to unauthorized ports.
  • Can be configured using environment variables or command line flags (but works out-of-the box).
  • IPv6 support.
  • Single binary, no dependencies.
  • Easy setup.
  • Optional client for local TCP connections tunneled through WebSockets.

Installation

  • Binaries for the latest commit can be downloaded here.
  • It can also be deployed to Heroku.
  • A Docker image is available: geek1011/easy-novnc:latest.
  • You can build your own binaries with go 1.13 or newer using go get github.com/pgaskin/easy-novnc or by cloning this repo and running go build.
