今天早些时候，下面的命令工作：
ssh ssh://[email protected] -i path/to/keyfile 现在它返回这个错误（有/无详细）：
权限被拒绝（公钥）
在主机上，当我尾巴/var/log/auth.log它显示：
invalid user ssh from ip.ip.ip.ip input_userauth_request: invalid user ssh connection closed by ip.ip.ip.ip
在工作时间和现在之间，我添加了一个用户（alex），并将其主目录设置为/home/ubuntu/alex 。 我也复制.bashrc ， .profile和其他一些文件到新的主目录。
Ubuntu的家是/home/ubuntu和.ssh位于里面。 .ssh有chmod 700
任何想法，我怎么搞砸了这个？ 所有的用户现在都讨厌我。
最奇怪的是，我的bitvise tunellier ssh允许我连接到主机，但我不能用上面的命令从git bash。
谢谢！
编辑：这里是/ etc / ssh / sshd_config：

你有没有做一些软件更新与新的默认configuration，而不是保持旧的？
我相信随着下面的留言评论，你不能使用SSH密钥。
#AuthorizedKeysFile％h / .ssh / authorized_keys
no为以下，没有密码login。
PasswordAuthentication no
你基本上locking了每个人。
