用ssh实现自动远程登录时遇到的问题

sccdyuebo

:help 按照书上的步骤，我用ssh-keygen -t rsa 生成了公钥和私钥（id-rsa.pub和id-rsa），并将id-rsa.pub拷到了远端的电脑上。但我在本机使用ssh IP地址，却仍要我输入密码（我没有用口令短语，所以没有用ssh-agent命令）。请问这到底是怎么回事？？？:help
SSH的版本是相同的OpenSSH_4.2p1, OpenSSL 0.9.7a Feb 19 2003，
OS都是AS3
下面是我键入的步骤：
[yb@dell bin]$ ./ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/yb/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/yb/.ssh/id_rsa.
Your public key has been saved in /home/yb/.ssh/id_rsa.pub.
The key fingerprint is:
14:4d:8f:f1:27:bf:99:8f:9d:a2:e3:68:ed:fa:6b:83 yb@dell

我把远端的id-rsa.pub 重命名为authorized_keys还是不行。

看一下远端.ssh目录的权限是不是700?拷贝到远端应当重命名为authorized_keys或者authorized_keys2,我的也是AS3,用这种方法16台主机之间互相登录没有问题.还有两边用户yb的UID是不是一样的,这个时候系统好象并不是认用户名的而是只认UID.
