Hi All,

I want to know is there any way to get connect to the remote host with ansible control server using rsa key.

Instead of using user name and password I want to use rsa key for authentication.

How can we do that?

Looking forward for reply.

Thanks & Regards  
Sumit Sahay

Hi Cava,

Thanks for your reply.

While doing this, we don’t need to enter user credential in host file?  
Is it so?

Looking for your reply.

hi only the first time you have to copy the public key and insert the pwd

for example with  
cat ~/.ssh/id\_rsa.pub | ssh user@hostname ‘cat \>\> .ssh/authorized\_keys’

or

ssh-copy-id -i ~/.ssh/mykey user@host

after when the key i present over the host  
you can cannect without any password
