SSH 連接問題 SSh Agent admitted failure to sign using the key

現有2台機器

1、服務器192.168.1.112

2、個人機192.168.1.110

要使110無需密碼通過ssh登入112

步驟

1、創建密鑰

1. miao@u32-192-168-1-110:~/.ssh$ ssh-keygen -t rsa  
2.   
3. Generating public/private rsa key pair.  
4. Enter passphrase (empty for no passphrase): (忽略)  
5. Enter same passphrase again: (忽略)  
6. Your identification has been saved in /home/miao/.ssh/id_rsa.  
7. Your public key has been saved in /home/miao/.ssh/id_rsa.pub.  

2、復制公密到www.linuxidc.com服務器 

1. miao@u32-192-168-1-110:~/.ssh$ scp id_rsa.pub [email protected]:/home/miao/.ssh/192.168.1.110  
2. [email protected]'s password:   
3. id_rsa.pub                                                                   100%  404     0.4KB/s   00:00      
4. miao@u32-192-168-1-110:~/.ssh$   

3、添加公密到192.168.112的信任區域 

view plain

1. miao@debian-192-168-1-112:~/.ssh$ cat 192.168.1.110 >> authorized_keys  
2. miao@debian-192-168-1-112:~/.ssh$   

注： 2，3兩步可由命令ssh-copy-id一步到位 
view plain

1. miao@Ubuntu-192-168-1-110:~/.ssh$ ssh-copy-id [email protected]  
2. Password:  
3. Now try logging into the machine, with "ssh '[email protected]'", and check in:  
4.   
5.   .ssh/authorized_keys  
6.   
7. to make sure we haven't added extra keys that you weren't expecting.  

4、啟動ssh-agent 

如果ssh 192.168.112返回 Agent admitted failure to sign using the key 
ps -Af|grep agent查看有無ssh-agent有無運行， miao@u32-192-168-1-110:~/.ssh$ ps -Af|grep agent 5、若沒有 添加id_rsa到ssh-agent miao@u32-192-168-1-110:~/.ssh$ ssh-agent
