SSH突然询问密码 一般问题
我有我的电脑（MacOSX10.9.4）和远程服务器（Ubuntu14.04.1LTS）。我使用SSH突然询问密码 一般问题,ssh,Ssh,我有我的电脑（MacOSX10.9.4）和远程服务器（Ubuntu14.04.1LTS）。我使用ssh-keygen创建了一个ssh密钥（没有密码），将公钥添加到服务器的.ssh/authorized_-keys，一切都很好。然后，今天早些时候，ssh又开始向我询问密码 是什么引起的 我真的不确定是什么原因导致了这一点——以下是我最好的猜测： 当我不小心复制了一个git存储库时，我不得不从远程服务器的主目录中删除一些文件（我没有提交或从那里做任何事情，只是复制了一些东西，然后rm'd了它们）。
ssh-keygen.ssh/authorized_-keysssh- 当我不小心复制了一个git存储库时，我不得不从远程服务器的主目录中删除一些文件（我没有提交或从那里做任何事情，只是复制了一些东西，然后
'd了它们）。从我的命令历史记录中可以看出，没有我删除的ssh相关文件，只有.git、.gitignore和各种*.sw？从vim遗留下来的文件rm - 我在远程服务器上运行了

rsyncrsyncchown root。为了解决这个问题，我必须更改文件所有者，然后重新登录。我在优胜美地上花了半个小时来解决这个问题。我所有的权限都正确，密钥在正确的位置，配置正确，等等
发生的情况是：我使用迁移助手将一些文件从这台机器传输到另一台机器，这导致交互式用户会话注销，但实际上没有重新启动机器，因此当我重新登录并启动
