我正在尝试设置仅RSA身份validationSSH / SFTP服务器。 SSH将主要用于RDC。 如果我使用密码authentication，一切正常。
我正在使用Putty Key Generator创build他的密钥，并将密钥粘贴到authorized_keys文件中并重新启动OpenSSH服务器。 我正在使用FileZillatestingSFTP连接，因为这是最重要的。 对于我的testing，我创build了没有密码更正的密钥。
它也不能使用标准的SSH连接。 它说“服务器拒绝我们的密钥”。 我已经重新创build了两次密钥与谷歌的指导双重检查，我很确定我做的正确。
我将密钥文件加载到设置/ SFTP下的FileZilla中，尝试连接，出现以下错误：断开连接：没有可用的身份validation方法。
我一直在玩整个晚上的不同的设置，我无法弄清楚。 这是我的sshd_config文件：

解决scheme是删除它的所有痕迹后重新安装copssh。 从头开始，我只从sshd_config文件中阻止密码login和rootlogin。 它工作正常。 我不知道当我第一次编辑sshd_config文件时发生了什么变化，因为我从备份恢复，并没有改变任何东西。 重新安装也是我在copssh论坛上find的另一个解决scheme。
