Connecting to Juniper devices

In this recipe, you will connect to Juniper devices via SSH in order to start managing the devices from Ansible. SSH is a common connection point, with the added benefit that network engineers are familiar with it.

1. Create private and public SSH keys in the ch05 working directory:

   root@cookbook-lab:~/cookbook-lab/chapters/ch05# ssh-keygen -t rsa -b 2048 -f Ansible_SSH_key (1)
   Generating public/private rsa key pair.
   Enter passphrase (empty for no passphrase):
   Enter same passphrase again:
   Your identification has been saved in Ansible_SSH_key
   Your public key has been saved in Ansible_SSH_key.pub
   The key fingerprint is:
   SHA256:2fQreD37u5d5IVmciHu1Lh8vLQZmFaU2FLNmbFvCAMk
   ... omitted output ...
   

The numbered reference from the preceding code is explained as follows:

(1) ssh-keygen is executed to generate the private and public keys:

We specify the encryption algorithm with the -t option. Here, it is set to rsa.
