Sample script
import paramiko
from getpass import getpass
import time
host = "csr1.test.lab"
username = 'admin1'
password = 'admin'
password = getpass("Enter password :")
session = paramiko.SSHClient()
session.set_missing_host_key_policy(paramiko.AutoAddPolicy())
session.load_host_keys('/home/evolve/.ssh/known_hosts')
session.set_missing_host_key_policy(paramiko.WarningPolicy())
session.load_system_host_keys()
key_pass = getpass("Enter Private Key Password:")
key_file = paramiko.RSAKey.from_private_key_file("/home/evolve/.ssh/01_id", key_pass)
session.connect(hostname=host,
username=username,
password=password,
pkey=key_file,
)
DEVICE_ACCESS = session.invoke_shell()
DEVICE_ACCESS.send('term length 0\n')
DEVICE_ACCESS.send('show ip int brie\n')
DEVICE_ACCESS.send('config t\n')
DEVICE_ACCESS.send('int lo0\n')
DEVICE_ACCESS.send('no shut\n')
#DEVICE_ACCESS.send('more pyenv\n')
time.sleep(3)
output = DEVICE_ACCESS.recv(65000)
print (output.decode())
print (output.decode('ascii'))
session.close()
