『以解决』利用公钥无密码登录ssh的问题

tomcat.xin

用ssh-keygen 重新生成了一个密钥对,但是没有使用默认的文件名，自己起了个文件名，上传后，就一切OK


严格按照网上的教程上传公钥到服务器
一开始一切顺利
后来locale系统重装了一次以后
把服务器上.ssh删除
重新安装网上的教程上传公钥到服务器，但是这次死活就不行了！
然后，在locale上用另外一个别人的ssh账户上传公钥，用别人的账户登录服务器，可以成功不用密码登录
可是我的账户死活就是不能无密码登录！！！
不知道我说清楚了没有？
ssh -v 信息如下：

2个登录过程能比较一下么？

pingz

会不会是这个？

虽然已经很久了，你的服务器上用的ssh版本号是多少？

对比了一下

1. 
   
2. 前面的一样
   

复制代码

成功无密码登录的代码如下：

1. 
   
2. debug1: Next authentication method: publickey
   
3. debug1: Trying private key: /home/xinchangpeng/.ssh/id_rsa
   
4. debug1: read PEM private key done: type RSA
   
5. debug1: Authentication succeeded (publickey).
   
6. debug1: channel 0: new [client-session]
   
7. debug1: Entering interactive session.
   
8. debug1: Sending environment.
   
9. debug1: Sending env LANG = en_US.UTF-8
   
10. Last login: Thu Oct 21 13:40:14 2010 from xxx
    
11. -bash-3.00$
    

复制代码

未成功的代码如下：

1. 
   
2. debug1: Next authentication method: publickey
   
3. debug1: Trying private key: /home/xinchangpeng/.ssh/id_rsa
   
4. debug1: read PEM private key done: type RSA
   
5. debug1: Authentications that can continue: publickey,gssapi-with-mic,password
   
6. debug1: Trying private key: /home/xinchangpeng/.ssh/id_dsa
   
7. debug1: Next authentication method: password
