04并将sftp chroot设置为我们的2个开发人员的/ var / www。 我遵循网上提供的指南（参考了其他几个） http://www.krizna.com/ubuntu/setup-ftp-server-on-ubuntu-14-04-vsftpd/并设置vsftpd和设置sshconfigurationsshd_config文件。 我安装了root：755的/ var / wwwpath。 一切工作正常，直到我抽出一些时间，一旦我回来，没有一个开发人员能够login。 我检查了设置，SSHconfiguration，目录权限，但我无法弄清楚它是什么。 我有一个类似的Ubuntu 14.04机器，sftp工作正常。 我匹配的设置，没有任何区别。 我试图使用WinSCP，每次我尝试连接时，系统会提示input密码，然后闪烁并返回主WinSCP屏幕。 检查validation日志，并说“密码已被用户接受”。 没有错误或警告。 试过使用Cyberduck，它说服务器的未知指纹。 允许或拒绝。 我检查了ECDSA.pub文件的服务器的指纹，这是正确的。 一旦我允许并input密码，在读取数据包的同时就会收到EOF，互操作性失败。
请帮忙！！
在我意识到我需要做什么之后，这是新的日志。
