Get-DnsServerRecursion在Windows Server中有什么用
时间: 2024-05-21 14:10:23 浏览: 13
Get-DnsServerRecursion是一条PowerShell命令,用于获取Windows Server上的DNS服务器递归设置。DNS服务器递归设置确定了DNS服务器是否可以向其他DNS服务器发出递归查询,以获取未知的DNS记录。这是一项重要的安全功能,因为不正确配置的递归设置可能会导致DNS缓存投毒攻击,从而使DNS服务器成为恶意攻击者的代理。使用Get-DnsServerRecursion命令可以帮助管理员快速检查和更改DNS服务器递归设置,从而提高服务器安全性。

Unfortunately, as an AI language model, I do not have access to your specific environment and cannot directly execute PowerShell commands. However, I can provide you with information about the Get-DnsServerRecursion PowerShell cmdlet.
The Get-DnsServerRecursion cmdlet retrieves the Recursion settings for a DNS server. Recursion is the process by which a DNS server resolves a query by recursively querying other DNS servers until it finds the answer. The cmdlet displays the following information:
- RecursionEnabled: Indicates whether recursion is enabled on the DNS server.
- RecursionTimeout: Specifies the maximum amount of time that the DNS server waits for a response from a recursive query.
- RecursionRetry: Specifies the number of times that the DNS server retries a recursive query before giving up.
- RecursionScope: Specifies the scope, or range of IP addresses, for which the DNS server provides recursion.
To use the Get-DnsServerRecursion cmdlet, open PowerShell and type the following command:
Get-DnsServerRecursion -ComputerName MyDnsServer
Replace "MyDnsServer" with the name or IP address of your DNS server. This cmdlet is only available on servers running the DNS Server role in Windows Server.

sudo apt-get update
```
2. 通过以下命令安装 ClickHouse 服务器。
```shell
sudo apt-get install -y clickhouse-server
```
3. 通过以下命令安装 ClickHouse 客户端。
```shell
sudo apt-get install -y clickhouse-client
```
安装完成后,您可以启动 ClickHouse 服务并使用 ClickHouse 客户端连接到 ClickHouse 服务器。
