## Parameters

* `protocol` \[enum: `tcp`/`udp`/`tls`\]
### Protocol

The protocol is specified as the argument of `<transport>` section.

```
<transport PROTOCOL>
</transport>
```

* \[enum: `tcp`/`udp`/`tls`\]
* Default: `tcp`

### General Setting

#### `linger_timeout`

| type | default | available transport type | version |
| :--- | :--- | :--- | :--- |
| integer | 0 | tcp, tls | 1.14.6 |

The timeout \(seconds\) to set `SO_LINGER`.

The default value `0` is to send RST rather than FIN to avoid lots of connections sitting in TIME_WAIT on closing.

You can set positive value to send FIN on closing.

{% hint style='info' %}
On Windows, Fluentd sends FIN without depending on this setting.
{% endhint %}

```
<transport tcp>
linger_timeout 1
</transport>
```

### TLS Setting

* `version`: \[enum: `TLS1_1`/`TLS1_2`/`TLS1_3`\]
