sftp key？

我在系统配置如下
1.ssh-keygen -t rsa -f /u/c201303/.ssh/id_rsa -N ""
ssh-keygen -t dsa -f /u/c201303/.ssh/id_dsa -N ""
2.cat id_rsa.pub >>authorized_keys
cat id_dsa.pub >>authorized_keys
3.ftp id_rsa.pub 和id_dsa.pub到对方服务器/u/c201303/.ssh
4 run ssh -vvv c201303@12.190.3.18 生成 known_hosts
但就这出幺蛾子。验证不过要密码，我收集了一些TRACE。希望大家帮我指正。谢谢！
