对于你们这些 Unix 高手来说，这可能是一个简单的问题，但我搞不懂，所以我试图从命令行通过 sftp 连接到 Windows 服务器，但远程拒绝连接。当我在详细模式下运行它时，我可以看到系统正在尝试使用我的一个公钥（在我的 ssh 配置中设置并用于我 ssh 连接到的另一台服务器）进行身份验证，而我想要的只是它要求我输入密码，以下是跟踪的净化版本：
sftp -v<username>@<remote_ip_address>

当我在装有 WinScp 或 Putty 的 Windows 机器上尝试此操作时，一切正常。但我需要在我的生产服务器 (Centos) 上安装此程序，我无法在生产服务器上安装这些程序或其他实用程序。PS：我也能在我的 Mac 上重现此问题，结果相同，但无法解决。任何帮助都将不胜感激。提前致谢！！
答案1
尝试：
sftp -o PubkeyAuthentication=no <user>@<server>
这应该会禁用您在本次会话中使用公钥的意愿。
