How to convert paramiko output to array

Posted on By Pythoneo

When working with remote servers using Paramiko, you might need to convert the output you receive from remote commands into a more structured and manageable format, such as a Python array. In this guide, we’ll walk you through the steps to convert Paramiko output to a Python array.

Establish an SSH Connection

First, establish an SSH connection with the remote server using Paramiko. Replace the placeholders with your server’s details.

hostname = 'your_server_hostname'
username = 'your_username'
password = 'your_password'

ssh_client = paramiko.SSHClient()
ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())

try:
    ssh_client.connect(hostname=hostname, username=username, password=password)
    print("Connected to the server successfully.")
except Exception as e:
    print("Error: ", str(e))

Execute Remote Commands

Next, execute remote commands on the server and capture their output.

command = 'your_remote_command_here'

try:
    stdin, stdout, stderr = ssh_client.exec_command(command)
    command_output = stdout.read().decode('utf-8')
except Exception as e:
    print("Error executing remote command: ", str(e))

Parse the Output into an Array

To convert the Paramiko output to an array, you can use regular expressions (regex) to split the output into individual elements based on a delimiter, such as a newline character.

output_array = re.split(r'\n', command_output)

Now, output_array contains the individual lines of the remote command’s output as array elements.

This can be particularly useful when automating tasks or managing remote servers programmatically.
