ssh - Windows ssh：权限被拒绝（公钥）

问题描述

我正在尝试使用公钥 ssh 到远程客户端，但我不断收到权限被拒绝（公钥）错误并且无法解决它。我已经尝试了所有其他在线解决方案，但仍然无法正常工作。我用 * 和 ip_add 替换了一些信息。我该如何解决这个问题？

解决方案

这是一个迟到的答案，但我有同样的问题

Windows 看不到隐藏的东西

第一件事（但与问题无关）：避免使用 Power Shell（它太强大），使用简单的 CMD 或最好使用 Git Bash（https://gitforwindows.org/）

其次，您的语法几乎没问题，但是您将密钥放在隐藏文件夹中 C:\Users\yourname\.ssh\id_rsa，并且应该将其放置在没有像这样隐藏的文件夹中 C:\Users\yourname\ssh\id_rsa，然后您可以像这样访问它：

C:\WINDOWS\system32> cd C:\Users\yourname\

C:\Users\yourname/> ssh <user>@<ssh_server> -p 22 -i ~/ssl/id_rsa

你知道在哪里？

debug1: No more authentication methods to try.

绝对意味着您的主机和远程上没有相同的密钥，或者这里有一个密钥而那里没有密钥（或这些的组合）它已经检查了所有密钥并说“没有更多的密钥可以尝试”。您必须以系统可以读取的方式在两个位置放置相同的密钥。你注意这 2 行：

debug1: identity file C:/Users/*/.ssh/id_rsa type 0 
debug1: key_load_public: No such file or directory

他无法读取本地隐藏文件夹中的密钥。所以......通过将它移动到一个未隐藏的文件夹中它会起作用。
