パスワードのないSSH localhostはFedora 14では機能しません。

私は次を実行します：

$ ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa 
$ cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

その後、sshdに/etc/ssh/sshd_config変更して再起動します。StrictModesno

私は持っています：

$ ssh localhost
Agent admitted failure to sign using the key.
dev@localhost's password: 

何が問題なの？パスワードのない操作を実行するにはssh localhost？

修正する:

$ ssh -v localhost
