在现代网络安全中,SSH免流（SSH Tunneling）是一项至关重要的技能，它能够帮助你在VPS（虚拟专用服务器）上安全地建立远程连接，避免数据被中间人截获或嗅探，如果你是网络管理员、开发人员或安全爱好者，这篇文章将为你揭示SSH免流的奥秘。

什么是SSH免流？

在VPS上搭建SSH免流，安全通信的秘密武器

SSH免流是一种通信机制,旨在在SSH连接中避免数据包被中间人截获或嗅探，通过使用公钥认证和端到端加密，SSH免流确保了通信的安全性，当你连接到VPS时，数据不会被第三方窃听或篡改。

为什么需要SSH免流？

在数字网络中,数据传输的安全性至关重要，传统的SSH连接可能会面临以下风险：

  1. 中间人攻击：攻击者可能在你和VPS之间设置障碍，窃听或篡改数据。
  2. man-in-middle 攻击：攻击者可以操控网络流量，伪造身份。
  3. 数据泄露：敏感信息（如密码、凭据）可能通过嗅探被获取。

通过SSH免流,你可以有效防止这些风险，确保通信的安全性。

如何在VPS上搭建SSH免流？

搭建SSH免流需要配置VPS的SSH服务器,并确保所有相关服务正常运行，以下是分步指南：

配置SSH公钥文件

你需要准备一个包含你VPS公钥的文件,这可以通过ssh-keygen工具生成。

ssh-keygen -t rsa -b 4096 > vps_key.txt

将生成的公钥文件vps_key.txt上传到VPS上，并确保它位于/root/.ssh/目录下。

修改SSH配置文件

在VPS的/etc/ssh/sshd_config文件中，添加以下内容：

[PublicKeyFile]
    $User
    /root/.ssh/vps_key.txt
[User]
    HostName
    authorized_keys=*
    HostAddress
    authorized_keys=*
    IdentityFile
    /root/.ssh/id_rsa
    HostKeyStrengthening
    no
    PermitRootLogin
    no
    IDENTITYAuthentication
    yes
    SSHKeyAuthentication
    yes
    SessionKeyAlgorithm
    ask
    SessionKeyStrength
    ask
    SSHKeyUsage
    signing,verify
    SSHKey fingersig=2

启用SSH免流

在/etc/ssh/sshd_config文件中，添加以下配置：

[Service]
    enabled = yes
[Network]
    PermitRootLogin = no
[NetworkHostKeys]
    HostKeyChecking = no
[Firewall]
    SSHPortForwarding = yes
