# 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
2023-02-05 10:34:57 +00:00
mappings:
- udp: false
source: 0.0.0.0:2222
targets: [127.0.0.1:22]
```
2023-02-05 10:34:57 +00:00
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.
