## wsserver.host and wsserver.port
These settings are for the
[aiohttp server](https://aiohttp.readthedocs.io/en/stable/index.html),
which is used to serve the
[WebSocket Event Stream API](../websocket-event-stream-api.html).
`wsserver.host` is where to bind the aiohttp server socket and
`wsserver.port` is the corresponding port.
If you want to allow connections from anyone, on port 9985,
set `wsserver.host` to 0.0.0.0 and `wsserver.port` to 9985.
**Example using environment variables**
```text
export BIGCHAINDB_WSSERVER_HOST=0.0.0.0
export BIGCHAINDB_WSSERVER_PORT=9985
```
**Example config file snippet**
```js
"wsserver": {
"host": "0.0.0.0",
"port": 65000
}
```
**Default values (from a config file)**
```js
"wsserver": {
"host": "localhost",
"port": 9985
}
```
