!!!! Read before starting: if ansible run as root >>>>> use root's id_rsa file !!!!
!!!! But if it's for Juniper, use the user account to log into the router !!!!
juniper.junos module does not send a file to the router, but use netconfig
1- create the Private key & Public key ( .pub) on the Client: ssh-keygen
2- copy the public key to the server: ssh-copy-id or just a sftp
3- To set up SSH agent to avoid retyping passwords, you can do:
4- SSH test ( will ask for the passphrase once!)
5- check the Local keys:
6- check the Remote keys:
1- create the private & Public key on the Client:
ssh-keygen ( press enter + enter the passphrase )
passphrase = Juniper1 ( same as: root/Juniper1, because is easier to remember)
/project # ssh-keygen
!!!!! default will use: root
!!!!! and will put it in /root/.ssh/
/project # ssh-keygen -t rsa -f /root/.ssh/id_rsa -P Juniper1 -C root
Generating public/private rsa key pair.
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:5O9zJGCqTGXyjvintT4ZjzFD7P0pYz6bwWMRPFYtYeY root
The key's randomart image is:

RSA:
-Asymmetric Encryption: Private and Public key
-#Diffie-Hellman
-2,048 bits (or 617 decimal digits )
-Rivest-Shamir-Adleman
Private Key: AES-128-CBC ???
AES:
-Symmetric Encryption Algorithms
-Block cipher ( 128-bit block message + 128-bit key) >> 128-bit cipher text
- Advanced Encryptiuon Standard
2- copy the public key to the server:
ssh-copy-id ansible@192.168.99.11
or just copy the file using ( if ssh-copy-id not supported ):
scp id_rsa.pub ansible@192.168.99.111:/var/home/ansible/
sftp ansible@192.168.99.11 ( then put /project/id_rsa.pub /var/home/ansible/id_rsa.pub )
( or with sftp tool like mobaxterm )
scp id_rsa.pub ansible@192.168.99.111:/var/home/
Password:

or

After a reboot of the server the key may change, will need to be reload on the vMX!

3- To set up SSH agent to avoid retyping passwords, you can do:
http://docs.ansible.com/ansible/intro_getting_started.html
$ ssh-agent bash
$ ssh-add ~/.ssh/id_rsa #here you load the Private key to be used
-l Lists fingerprints of all identities currently represented by the agent.
[root@hp8300 ~]# ssh-add -l

-L Lists public key parameters of all identities currently represented by the agent.
[root@hp8300 ~]# ssh-add -L

5- check the Local keys:
6- check the Remote keys:
