A meta VPN work in progress proof of concept

Disclaimer: This is just a playground git repository to drop my ideas on the subject. Don't expect any working tools.

Configuration of a node

  1. Initialize

Each node needs to be initialized and its identification and keys created.

# ./metavpn-init

2a) Create inital YAML configuration file on a trusted node

# ./metavpn-config

2b) Export the public key for the trusted node

# ./metavpn-identify

  1. Add new node to the configuration on a trusted node

    ./metavpn-add

Synchronization

Basic mechanisms:

  • All new nodes talk to a configured reachable node.
  • All get registered.
  • All retrieve updated configuration.

Multiple nodes, split and merge

  • When two nodes offer a signed configuration, how do they synchronize? Do we use a timestamp or a Git repo or whatever? What if I have signing keys in two places, i.e. multiple trusted nodes?

Terminology

Node : A system installation using metavpn. Connected node : A node that is part of the VPN network. Trusted node : A node with the authority to distribute a list of nodes and their keys.
