添加一个新用户和他的pub密钥到〜/ .ssh / authorized_keys后，我无法SSH到我的切片（权限被拒绝（公钥））。
所以我改变了（在/ etc / ssh / sshd_config）ChallengeResponseAuthentication从no到yes ，并将他添加到AllowUsers。 然后，尝试SSH：连接closuresmy.IP.here
所以我把ChallengeResponseAuthentication改回了no，
`sudo kill `cat /var/run/sshd.pid` && /usr/sbin/sshd` 此后我无法使用我的pipe理员用户（ piotr ）login：由my.IP.hereclosures的连接。

答案是在那个日志里：
未知键types“—– BEGIN”
看起来像你不知何故搞砸了你的私人密钥，SSH不能再读取它。
未知的密钥types“—– BEGIN”即使在正常连接中也会出现。 这不是什么坏事。 我也得到这些：debug2：key_type_from_name：未知的键types' – BEGIN'debug2：key_type_from_name：未知的键types'proc -type：'debug2：key_type_from_name：未知键types'DEK-信息：'debug2：key_type_from_name：未知键types“—– END”
在我所有的连接（公钥validation与否）
