# Synapse demo setup

DO NOT USE THESE DEMO SERVERS IN PRODUCTION

Requires you to have a Synapse development environment setup.

The demo setup allows running three federation Synapse servers, with server names `localhost:8080`, `localhost:8081`, and `localhost:8082`.

You can access them via any Matrix client over HTTP at `localhost:8080`, `localhost:8081`, and `localhost:8082` or over HTTPS at `localhost:8480`, `localhost:8481`, and `localhost:8482`.

To enable the servers to communicate, self-signed SSL certificates are generated and the servers are configured in a highly insecure way, including:

- Not checking certificates over federation.
- Not verifying keys.

The servers are configured to store their data under `demo/8080`, `demo/8081`, and `demo/8082`. This includes configuration, logs, SQLite databases, and media.

Note that when joining a public room on a different HS via "#foo:bar.net", then you are (in the current impl) joining a room with room_id "foo". This means that it won't work if your HS already has a room with that name.

## Using the demo scripts

There's three main scripts with straightforward purposes:

- `start.sh` will start the Synapse servers, generating any missing configuration.
  - This accepts a single parameter `--no-rate-limit` to "disable" rate limits (they actually still exist, but are very high).
- `stop.sh` will stop the Synapse servers.
- `clean.sh` will delete the configuration, databases, log files, etc.

To start a completely new set of servers, run:

    ./demo/stop.sh; ./demo/clean.sh && ./demo/start.sh
