Paramiko for servers

Paramiko can be used to manage servers through SSHv2 as well. Let's look at an example of how we can use Paramiko to manage servers. We will use key-based authentication for the SSHv2 session.

In this example, I used another Ubuntu virtual machine on the same hypervisor as the destination server. You can also use a server on the VIRL simulator or an instance in one of the public cloud providers, such as Amazon AWS EC2.

We will generate a public-private key pair for our Paramiko host:

ssh-keygen -t rsa

This command, by default, will generate a public key named id_rsa.pub, as the public key under the user home directory ~/.ssh along with a private key named id_rsa. Treat the private key with the same attention as you would ...
