# hesiod.conf.5

`hesiod.conf` — Hesiod 库的配置文件

## 名称

`hesiod.conf`

## 描述

`hesiod.conf` 文件决定 Hesiod 库的行为。空行和以 `#` 字符开头的行将被忽略。所有其他行应采用 `variable` = `value` 的形式，其中 `value` 应为单个单词。可用的 `variables` 和 `values` 如下：

**`lhs`** 指定用于 Hesiod 查询的域前缀。在几乎所有情况下，你应指定 "`lhs=.ns`"。如果未指定 lhs 值，默认值为无域前缀，这与大多数 Hesiod 域不兼容。

**`rhs`** 指定默认的 Hesiod 域；此值可被 `HES_DOMAIN` 环境变量覆盖。必须指定一行 rhs 才能使 Hesiod 库正常工作。

**`classes`** 指定 Hesiod 应在哪些 DNS 类中进行查找。可能的值为 `IN`（首选类）和 `HS`（已弃用的类，仍被某些站点使用）。你可以指定两个类并以逗号分隔，先在一个类中查找，如果该类中没有条目再在另一个类中查找。classes 变量的默认值为 "`IN,HS`"。

## 参见

hesiod(3)

## 缺陷

`lhs` 的默认值可能应该更合理一些。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://book.bsdcn.org/man/man5/hesiod.conf.5.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
