我有一些问题login到一台服务器通过密钥SSH
这是客户端输出：ssh'[email protected]'-p 2201 -v

不知道这里发生了什么事情，当客户端尝试login时，SSHD会自杀。 它是一个OpenVZ容器中的Debian 7（主机也是Debian 7）
通过密码SSHlogin工作正常，我只是为了testing密钥login被禁用它，它总是要求input密码，当试图进行密钥login（因为密钥没有工作）。
我将％HOME％设置为700，.ssh也设置为700，文件内部为500
我用ssh-copy-id复制密钥（并且再次执行）。 我使用的密钥有点旧了，所以我没有为这个SSH客户端创build它们。 我无法findauthorized_keys中的任何错误
这个来自sshd_config
RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile %h/.ssh/authorized_keys
仍然失败的公钥。
顺便说一句。 同时我试图从另一个客户端访问同一台服务器：ssh-keygen -t rsa ssh-id-copy ssh ..
它的工作，所以它必须是在客户端上面的东西
首先检查基本知识：
你的.ssh / authorized_keys的内容是正确的？ 公钥没有额外的换行符？
该文件的权限是否正确？ sshd对此非常严格：你应该看到很多600甚至400（只读的根目录）。 引用你的日志：
