A is correct Connect via SSH and initialize the NETCONF session. First attempts the publickey authentication method and then password authentication. To disable attempting publickey authentication altogether, call with allow_agent and look_for_keys as False. host is the hostname or IP address to connect to port is by default 830 (PORT_NETCONF_DEFAULT), but some devices use the default SSH port of 22 so this may need to be specified https://ncclient-fredgan.readthedocs.io/_/downloads/en/sphinx_version/pdf/
