The below python script is use to auto login on jump server from local system and form tunnel with storage box without any addition package on any servers
Install paramiko module on local machine.
Run the below script from local machine.
import paramiko
from sshtunnel import SSHTunnelForwarder
with SSHTunnelForwarder(
   ('servername', 22),		#jump server address
    ssh_username='ajay.prajapati',
    ssh_pkey=paramiko.RSAKey.from_private_key_file("/root/.ssh/id_rsa"),
    #ssh_private_key_password="*******",
   remote_bind_address=("*.*.*.*", 22), #storage box ip address
   local_bind_address=('127.0.0.1', 10023)
) as tunnel:
   client = paramiko.SSHClient()
	#client.load_system_host_keys()
   client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
   client.connect(hostname='127.0.0.1', username="root", password="****", port=10023, look_for_keys=False)
	# do some operations with client session
   stdin, stdout, stderr = (client.exec_command('./datapull.sh')) # it will run the datapull.sh which is on storage box.
   print stdout.readlines()
   print stderr.readlines()
   client.close()
