04 并为我们的 2 名开发人员设置 sftp chroot 到 /var/www。我遵循了网上提供的指南（也参考了其他一些指南） http://www.krizna.com/ubuntu/setup-ftp-server-on-ubuntu-14-04-vsftpd/ 并设置 vsftpd 和在 sshd_config 文件中设置 ssh 配置。我为 /var/www 路径设置了 root:root 和 755。在我休息一段时间之前，一切都运行良好，当我回来时，没有一个开发人员能够登录。我检查了设置、ssh 配置、目录权限，但我无法弄清楚可能是什么问题。我有一台类似的 ubuntu 机器 14.04，sftp 在上面运行良好。我匹配了设置，没有任何区别。我尝试使用 WinSCP，每次我尝试连接时，系统都会提示我输入密码，然后它会闪烁并返回到 WinSCP 主屏幕。检查了身份验证日志，它只显示“用户密码已被接受”。没有错误或警告。尝试使用 Cyberduck，它显示服务器的指纹未知。允许或拒绝。我根据 ECDSA.pub 文件检查了服务器的指纹，它是正确的。一旦我允许并输入密码，我在读取数据包时会收到 EOF，互操作性失败。
请帮忙！！
这是我意识到我需要做什么之后的新日志。
