Synopsis

  • This connection plugin provides a connection to remote devices over the SSH NETCONF subsystem. This connection plugin is typically used by network devices for sending and receiving RPC calls over NETCONF.
  • Note this connection plugin requires ncclient to be installed on the local Ansible controller.

Requirements

The below requirements are needed on the local controller node that executes this connection.

  • ncclient

Parameters

Parameter Choices/Defaults Configuration Comments
host
string
Default:
"inventory_hostname"
var: ansible_host
Specifies the remote device FQDN or IP address to establish the SSH connection to.
host_key_checking
boolean
    Choices:
  • no
  • yes
ini entries:

[defaults]
host_key_checking = yes

[paramiko_connection]
host_key_checking = yes

env:ANSIBLE_HOST_KEY_CHECKING
env:ANSIBLE_SSH_HOST_KEY_CHECKING
env:ANSIBLE_NETCONF_HOST_KEY_CHECKING
var: ansible_host_key_checking
var: ansible_ssh_host_key_checking
var: ansible_netconf_host_key_checking
Set this to "False" if you want to avoid host key checking by the underlying tools Ansible uses to connect to the host
import_modules
boolean
    Choices:
  • no
  • yes
ini entries:

[ansible_network]
import_modules = no

env:ANSIBLE_NETWORK_IMPORT_MODULES
var: ansible_network_import_modules
Reduce CPU usage and network module execution time by enabling direct execution. Instead of the module being packaged and executed by the shell, it will be directly executed by the Ansible control node using the same python interpreter as the Ansible process. Note- Incompatible with asynchronous mode. Note- Python 3 and Ansible 2.9.16 or greater required. Note- With Ansible 2.9.x fully qualified modules names are required in tasks.
look_for_keys
boolean
    Choices:
  • no
  • yes
ini entries:

[paramiko_connection]
look_for_keys = yes

env:ANSIBLE_PARAMIKO_LOOK_FOR_KEYS
Enables looking for ssh keys in the usual locations for ssh keys (e.g. :file:`~/.ssh/id_*`).
netconf_ssh_config
string
ini entries:

[netconf_connection]
ssh_config = None

env:ANSIBLE_NETCONF_SSH_CONFIG
var: ansible_netconf_ssh_config
This variable is used to enable bastion/jump host with netconf connection. If set to True the bastion/jump host ssh settings should be present in ~/.ssh/config file, alternatively it can be set to custom ssh configuration file path to read the bastion/jump host settings.
network_os
string
var: ansible_network_os
Configures the device platform network operating system. This value is used to load a device specific netconf plugin. If this option is not configured (or set to auto), then Ansible will attempt to guess the correct network_os to use. If it can not guess a network_os correctly it will use default.
password
string
var: ansible_password
var: ansible_ssh_pass
var: ansible_ssh_password
var: ansible_netconf_password
Configures the user password used to authenticate to the remote device when first establishing the SSH connection.
persistent_command_timeout
integer
Default:
30
ini entries:

[persistent_connection]
command_timeout = 30

env:ANSIBLE_PERSISTENT_COMMAND_TIMEOUT
var: ansible_command_timeout
Configures, in seconds, the amount of time to wait for a command to return from the remote device. If this timer is exceeded before the command returns, the connection plugin will raise an exception and close.
persistent_connect_timeout
integer
Default:
30
ini entries:

[persistent_connection]
connect_timeout = 30

env:ANSIBLE_PERSISTENT_CONNECT_TIMEOUT
var: ansible_connect_timeout
Configures, in seconds, the amount of time to wait when trying to initially establish a persistent connection. If this value expires before the connection to the remote device is completed, the connection will fail.
persistent_log_messages
boolean
    Choices:
  • no
  • yes
ini entries:

[persistent_connection]
log_messages = no

env:ANSIBLE_PERSISTENT_LOG_MESSAGES
var: ansible_persistent_log_messages
This flag will enable logging the command executed and response received from target device in the ansible log file. For this option to work 'log_path' ansible configuration option is required to be set to a file path with write access.
Be sure to fully understand the security implications of enabling this option as it could create a security vulnerability by logging sensitive information in log file.
port
integer
Default:
830
ini entries:

[defaults]
remote_port = 830

env:ANSIBLE_REMOTE_PORT
var: ansible_port
Specifies the port on the remote device that listens for connections when establishing the SSH connection.
private_key_file
string
ini entries:

[defaults]
private_key_file = None

env:ANSIBLE_PRIVATE_KEY_FILE
var: ansible_private_key_file
The private SSH key or certificate file used to authenticate to the remote device when first establishing the SSH connection.
proxy_command
string
Default:
""
ini entries:

[paramiko_connection]
proxy_command =

env:ANSIBLE_NETCONF_PROXY_COMMAND
var: ansible_paramiko_proxy_command
var: ansible_netconf_proxy_command
Proxy information for running the connection via a jumphost.
This requires ncclient >= 0.6.10 to be installed on the controller.
remote_user
string
ini entries:

[defaults]
remote_user = None

env:ANSIBLE_REMOTE_USER
var: ansible_user
The username used to authenticate to the remote device when the SSH connection is first established. If the remote_user is not specified, the connection will use the username of the logged in user.
Can be configured from the CLI via the --user or -u options.
