/etc/ssh/sshd_config配置

在修改`/etc/ssh/sshd_config`文件时，你需要执行以下步骤来进行配置：

1. 执行命令`vi /etc/ssh/sshd_config`来编辑该文件。
2. 找到一行以`#Port 22`开头的代码，并在其下面添加一行`Port 5000`。这将更改SSH的端口号为5000。
3. 保存并关闭文件。
4. 重启SSH服务以使配置生效，可以使用命令`/etc/init.d/sshd restart`来重启服务。

需要注意的是，这个配置文件的路径是`/etc/ssh/sshd_config`，而不是`/etc/ssh/sshd/`。另外，根据的引用，如果你的系统是CentOS 7，修改SSHD端口还涉及到SELinux和防火墙的配置，你也需要进行相应的更改来确保新的端口可以正常工作。至于的引用中提到的限制用户登录IP的方法，你可以根据需要选择其中一种方法进行配置。第一种方法是修改`/etc/hosts.allow`和`/etc/hosts.deny`文件，将允许通过的IP写入`/etc/hosts.allow`文件中，然后重启SSH服务以使配置生效。第二种方法是修改`/etc/ssh/sshd_config`文件，将允许登录的用户和IP写入配置文件中，并将不允许登录的用户和IP写入配置文件中，然后重启SSH服务以使配置生效。具体的配置方法可以参考的引用内容。

/etc/ssh/sshd_config

The /etc/ssh/sshd_config file is a configuration file for the OpenSSH server daemon (sshd). It contains various settings that determine the behavior of the sshd service, including:

- Port number: The TCP/IP port number on which the sshd service listens for incoming connections. The default is 22.
- Authentication methods: The authentication methods that are allowed for sshd connections, including password, public key, and keyboard interactive.
- PermitRootLogin: Whether or not the root user is allowed to log in via SSH. This is typically set to "no" for security reasons.
- Protocol version: The version of the SSH protocol that is allowed for incoming connections. The default is 2.
- HostKey: The location of the host key file used to identify the server to clients. This should be kept secure.
- AllowUsers/AllowGroups: A list of users or groups that are allowed to connect to the sshd service.
- X11Forwarding: Whether or not X11 forwarding is allowed for incoming connections.
- MaxAuthTries: The maximum number of authentication attempts that are allowed before the connection is terminated.

These are just a few examples of the many settings that can be configured in the /etc/ssh/sshd_config file. It is important to carefully review and configure these settings to ensure the security and proper functioning of the sshd service.

Vi /etc/ssh/sshd_config

您可以使用vi编辑器来编辑/etc/ssh/sshd_config文件。以下是一些步骤：

1. 打开终端并输入以下命令：vi /etc/ssh/sshd_config
这将使用vi编辑器打开sshd_config文件。

2. 在vi编辑器中，您可以使用方向键移动光标到需要修改的位置。按下i键或insert键以进入插入模式。

3. 在插入模式下，您可以进行修改。根据您的需求，您可以更改监听的IP地址、禁用协议版本1、限制可登录用户等等。请注意，每个修改后的行都需要以换行符结尾。

4. 修改完成后，按下Esc键退出插入模式。然后输入:wq!并按下回车键以保存文件并退出vi编辑器。

请注意，这些步骤仅供参考，您可以根据您的需求进行相应的修改。同时，为了确保安全性，请确保在编辑配置文件之前备份原始文件，并在修改后重新启动sshd服务以使配置生效。
