## Environment Variables
Environment variables introduced in 0.4.7 will override anything specified in `config.json`. This is useful for settings that may be per-node, or in a container environment. These are optional and will default to whatever their peer config.json settings are
* **LISTEN** - _string_ - IP address node should listen on for client connections, defaults to `127.0.0.1`. Peer is **listen.ip**
* **PORT** - _integer_ - Port node should listen on for client connections, defaults to `2222`. Peer is **listen.port**
* **SOCKETIO_ORIGINS** - _array_ - COORS origins to allow connections from to socket.io server, defaults to `localhost:2222`. Changed in 0.3.1, to enable previous, less secure, default behavior of everything use `*:*` (not recommended). Check [#240](../../issues/240). Peer is **socketio.origins**
* **SOCKETIO_PATH** _string_ - Path to socket.io client files. Default: `/ssh/socket.io`. Peer is **socketio.path**
* **SOCKETIO_SERVECLIENT** _boolean_ - serve the socket.io client. This is built into the custom javascript, so you shouldn't need this. Kept as an option just in case. Default: `false`. Peer is **socketio.serveClient**
