Authentication failed/ Netmiko

DOTTRAM commented 2 years ago

Hello. I using this code. But i cant to connect devices.

`from netmiko import ConnectHandler import getpass

my_devices = ['10.42.49.69', '10.42.49.66'] #list of devices device_list = list() #create an empty list to use it later

for device_ip in my_devices: device = { "device_type": "cisco_ios", "host": device_ip, "username": "ciscogtkz", "password": "Jkbvgbflf80", } device_list.append(device)

print(device_list) #list of dictionaries

for each_device in device_list: connection = ConnectHandler(**each_device) print(f'Connecting to {each_device["host"]}') output = connection.send_command('show run | incl hostname') print(output) connection.disconnect()`

I have next issue C:\Users\Администратор\PycharmProjects\pythonProject3\venv\Scripts\python.exe C:\Users\Администратор\PycharmProjects\pythonProject3\Cisco\Test333.py [{'device_type': 'cisco_ios', 'host': '10.42.49.69', 'username': 'ciscogtkz', 'password': 'Jkbvgbflf80'}, {'device_type': 'cisco_ios', 'host': '10.42.49.66', 'username': 'ciscogtkz', 'password': 'Jkbvgbflf80'}] Traceback (most recent call last): File "C:\Users\Администратор\AppData\Local\Programs\Python\Python310\lib\site-packages\netmiko\base_connection.py", line 1046, in establish_connection self.remote_conn_pre.connect(**ssh_connect_params) File "C:\Users\Администратор\AppData\Local\Programs\Python\Python310\lib\site-packages\paramiko\client.py", line 435, in connect self._auth( File "C:\Users\Администратор\AppData\Local\Programs\Python\Python310\lib\site-packages\paramiko\client.py", line 766, in _auth raise saved_exception File "C:\Users\Администратор\AppData\Local\Programs\Python\Python310\lib\site-packages\paramiko\client.py", line 753, in _auth self._transport.auth_password(username, password) File "C:\Users\Администратор\AppData\Local\Programs\Python\Python310\lib\site-packages\paramiko\transport.py", line 1564, in auth_password return self.auth_handler.wait_for_response(my_event) File "C:\Users\Администратор\AppData\Local\Programs\Python\Python310\lib\site-packages\paramiko\auth_handler.py", line 259, in wait_for_response raise e paramiko.ssh_exception.AuthenticationException: Authentication failed.

During handling of the above exception, another exception occurred:

Common causes of this problem are:

Invalid username and password
Incorrect SSH-key file
Connecting to the wrong device

Device settings: cisco_ios 10.42.49.69:22

Authentication failed.

Process finished with exit code 1

Then i connect. I am write this date. May be i need change "username" to "logins as" and "password" to "Password". I tryed this. But it still doesn't work. How fix this prolblem? login as: dottram Using keyboard-interactive authentication. Password: C2960-3_chelnygaz#

What is the vendor and model that you are connecting to?

Can you post the show version output here?

Things you might try to fix this:

Explicitly set your pattern using the expect_string argument.
Increase the read_timeout to a larger value.

You can also look at the Netmiko session_log or debug log for more information. Process finished with exit code 1

Use Netmiko's save_config() method (for saving running-config to startup-config).

Thank you so much. Its Working. How about a device who had long connection without tacacs? What need write in the code to be fix this?
