我已经验证了权限（.ssh 为 700，./ssh/* 为 600），检查了文件 sshd_config 的配置，但服务器继续要求输入密码，这是日志：

你能帮我提供一些建议吗？
答案1
如果您有权访问服务器，则更重要的帮助可能来自服务器端。在服务器端，停止 sshd。如果服务器端是 HP-UX，/sbin/init.d/secsh stop将为您执行此操作。然后，您需要使用命令以调试模式启动 sshd /usr/sbin/sshd -ddd。此时，请确保没有其他人通过 ssh 访问此计算机，因为调试模式下的 sshd 只允许一个传入连接。
然后，您转到 Linux 计算机并发出命令ssh -vvv hpux_server。此时，并排比较调试输出。我确信，您很快就会发现问题出在哪里。我敢打赌，私钥和公钥 ssh 不匹配，这是由于文件格式造成的，但我当然也可能是错的。
如果您不明白，请发布客户端和服务器的调试输出，以供大家查看。
