public key無法登入怎麼辦? - Linux

情況是這樣的,昨天不慎把自己home底下的.ssh給誤刪掉了,

導致無法登入.為此我產生了一組新的key,public key就給

了管理員了,private就自己留著了. 管理員的操作如下:

(id_rsa.pub是public key)

1. $ mkdir /home/pipidog/.ssh
2. $ chomd 700 /home/pipidog/.ssh
3. put id_rsa.pub in /home/pipidog/.ssh <-- not a command !
4. $ cat id_rsa.pub >> /home/pipidog/.ssh/authorized_keys
5. $ chomd 644 /home/pipidog/.ssh/authorized_keys

看起來沒什麼問題,.ssh改成644, authorize_keys也改成700

但是登入的時候,總是被refuse.所以就用ssh -v 來debug了一下,但是

實在看不懂問題究竟出在哪裡. 不曉得誰可以指點一下?
