connect to IOS XR Always-On Sandbox using ncclient

EvanC · ‎08-02-2021

I am testing the connection to IOS XR Always-On Sandbox using ncclient.

The code should be quite straight forward

from ncclient import manager

with manager.connect(
    host='sandbox-iosxr-1.cisco.com',                 # IP address of device
    port=830,                       # Port to connect to
    username='admin',                # SSH Username
    password='C1sco12345',                # SSH Password
    hostkey_verify=False,            # Allow unknown hostkeys not in local store
    device_params={'name':'iosxr'}  # Device connection parameters
) as m:                             # Context manager reference, i.e. instance of connected manager
    # Print out the NETCONF XML capabilities as reported by the device
    print(m.server_capabilities)

Unfortunately, I'v got AnthenticationError again

ncclient.transport.errors.AuthenticationError: AuthenticationException('Authentication timeout.')

Any idea?

Ok, I fix this issue by adding a few more parameters in manager.connect()

Here is the modified code:

with manager.connect(
        host=router["host"],
        port=router["netconf_port"],
        username=router["username"],
        password=router["password"],
        hostkey_verify=False,
        device_params={'name':'iosxr'}, 
        look_for_keys=False,
        allow_agent=False
        ) as m:
