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。

Permission denied (publickey).

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。
