github Permission denied (publickey)

昨天在linux机子上装上了git，结果在连接github的时候出现 Permission denied (publickey)，然后按照http://help.github.com/ssh-issues/提示还是没有解决问题。

上面是调试信息，后来不得已我给github的管理员发了封求救邮件（把上面的信息发给他们），发完之后才意识到昨晚是平安夜，谁知道今天早上竟然收到回复了（太敬业了）。

It seems the key you have added to your account is bogus. Could you make sure you copy the id_rsa.pub contents without changing anything.

按照他们的回复我发现那个publickey是我通过Secure CRT连接上用vim选择后右键复制的，我发现貌似中间有很多多余的空格，这个可能与我vim的设置有关吧，于是我用cat复制那个pubkey，然后连接就ok了。

window下面可以用gui里面的帮助复制pubkey。

 

我郁闷的是为什么有多余的空格，那个github中Account Settings” > Click “SSH Public Keys” > Click “Add another public key”的publickey还可以通过。
