不幸的是，我不能通过sftp连接到我的VPS：
这是我的sshd_config ：

任何想法如何解决这个问题？
这很可能意味着/usr/lib/openssh/sftp-server不存在。
确保Subsystem指令指向一个现有的path：
Subsystem sftp /usr/lib/openssh/sftp-server
或者实际上，现在你通常使用internal-sftp代替：
Subsystem sftp internal-sftp
请参阅OpenSSH：internal-sftp和sftp-server之间的区别 。
对我来说，这是客户端configuration错误。 127代码意味着命令没有find。 我改变了WinSCPconfiguration错误地使用“/ bin / sftp-server”而不是“默认”。 检查你的客户端configuration。
在我的，sftp服务器的完整path是在configuration文件，但没有工作。 我添加了“Subsystem sftp internal-sftp”，它开始工作。 谢谢！
