我无法通过WinSCP或sftplogin到我的Ubuntu（12.04 LTS）服务器。 之前在/ etc / ssh中存在ssh_host_ *文件的权限问题。 这是我尝试从另一个目录，这显然已经改变了一些其他文件的权限chmod -R之后。
我试过了sftp -P port-vv username@serverip ，它有下面的输出。

确保你的〜/ .profile（或者你的特定shell的等价物）不会产生任何输出。
确保sshd_config指向一个有效的sftp二进制文件
要重置文件权限，我使用了以下链接，它已成功将所有权限更改为默认的http://sysadminnotebook.blogspot.in/2012/06/how-to-reset-folder-permissions-to.html
