我试图连接到远程服务器使用SSH，但我有Permission denied (publickey). 。
我已经经历了所有可能的原因，我可以build议和其他问题的build议。
那么，什么给ssh -v ：

这是在服务器上的auth.log发现的（不是很多）：
Apr 1 12:15:33 host-07 sshd[23955]: Connection closed by --my-client-ip-- [preauth]
我应该说这个客户机很老，它有Centos 5.但是在我开始深入挖掘之前，我需要确定。
任何想法我怎么能至less弄清楚究竟出了什么问题？

如果你有root用户，用sshd -D -d在前台运行sshd，在debug模式下运行。 你需要先停止sshd守护进程。 服务器给出了关于密钥失败原因的更多具体信息。
你提到这个文件是0700.什么是.ssh？ 它也必须是0700。
