Open file to read/write /append get the configuration of cisco. Explains about 'with' statement. import paramiko import time from getpass import getpass username = 'admin' password = 'admin' DEVICE_LIST = open ('09_devices') for RTR in DEVICE_LIST: print ('\n #### Connecting to the device ' + RTR.strip() + '####\n' ) SESSION = paramiko.SSHClient() SESSION.set_missing_host_key_policy(paramiko.AutoAddPolicy()) SESSION.connect(RTR,port=22, username=username, password=password, look_for_keys=False, allow_agent=False) DEVICE_ACCESS = SESSION.invoke_shell() COMMANDS = open ('09_config') for LINES in COMMANDS: time.sleep(1) DEVICE_ACCESS.send(str(LINES)) time.sleep(3) output = DEVICE_ACCESS.recv(65000) print (output.decode('ascii')) SESSION.close #PythonOpenfile #PythonOpenReadWriteAppend #PythonCiscoConfiguration
