# Rustocat

Rustocat is a simple socat alternative with way less features, but it has a config file.

## Config File

Configs can be either yaml or json and can be located in /etc/rustocat.{yaml|json} or in the current working directory as config.{yaml|json}.

```yaml
mappings:
  - udp: false
    source: 0.0.0.0:2222
    targets: [127.0.0.1:22]
```

There is support for UDP and TCP sockets. Each socket can have multiple targets.

When multiple targets are set, it will randomly pick one of them.

## Live Changes

It is designed to live reconfigure itself. To trigger a change, send the signal `SIGHUP` to the process. This will re-read the config file and adjust the sockets and targets accordingly.

All existing connections will stay as they are, but removed sources are closed from further connections.
