vban-bridge-server

This is the server-side for the vban-bridge. It acts as a hub where clients can connect and share audio streams.

The UDP packets from VBAN are encapsulated in a secure TLS connection and sent to the server, which in turn sends the data to all connected clients.

The clients can then re-emit those UDP packages locally, creating a virtual network.

Certificates

The communication is encrypted with TLS. The certificate and key must be generated and stored in the config folder, following this structure:

- config
| - server.crt
| - server.key

You can follow this guide to generate ED25519 certificates. The configuration file is already provided.

cd config
openssl genpkey -algorithm ED25519 > server.key
openssl req -new -out server.csr -key server.key -config openssl-25519.cnf
openssl x509 -req -days 9999 -in server.csr -signkey server.key -out server.crt

Password

The password can be configured in the config/config.json file. Clients must use this password when they first connect to the server. Following connections do not require typing the password, as the client's identity is saved on the server.

Running

Steps to get the server up and running:

• Clone this repository
• Generate the server certificates
• Change the relevant configurations
• Run npm install
• Run npm run compile to compile the Typescript source
• Run npm start
