Server Configuration

Function Documentation

int nc_server_config_load_modules ( struct ly_ctx ** ctx )

Implements all the required modules and their features in the context. Needs to be called before any other configuration functions.

If ctx is :

NULL: a new context will be created and if the call is successful you have to free it,
non NULL: modules will simply be implemented.

Implemented modules: ietf-netconf-server, ietf-x509-cert-to-name, ietf-crypto-types, ietf-tcp-common, ietf-ssh-common, iana-ssh-encryption-algs, iana-ssh-key-exchange-algs, iana-ssh-mac-algs, iana-ssh-public-key-algs, ietf-keystore, ietf-ssh-server, ietf-truststore, ietf-tls-server and libnetconf2-netconf-server.

Note that the SSH authentication depends on the value of the 'local-users-supported' feature in the ietf-ssh-server module. If the feature, and its dependent if-features, are disabled, the SSH authentication will use the system users. Otherwise, the SSH authentication will use the local users from the configuration (the default).

Parameters

[in,out] ctx Optional context in which the modules will be implemented. Created if *ctx is null.

Returns: 0 on success, 1 on error.

int nc_server_config_setup_diff ( const struct lyd_node * diff )

Configure server based on the given diff.

Context must already have implemented the required modules, see nc_server_config_load_modules().

Parameters

[in] diff YANG diff belonging to either ietf-netconf-server, ietf-keystore or ietf-truststore modules. The top level node HAS to have an operation (create, replace, delete or none).

Returns: 0 on success, 1 on error.

int nc_server_config_setup_data ( const struct lyd_node * data )

Configure server based on the given data.

Behaves as if all the nodes in data had the replace operation. That means that the current configuration will be deleted and just the given data will be applied. Context must already have implemented the required modules, see nc_server_config_load_modules().

Parameters

[in] data YANG data belonging to either ietf-netconf-server, ietf-keystore or ietf-truststore modules. This data must be valid. No node can have an operation attribute.

Returns: 0 on success, 1 on error.

int nc_server_config_setup_path	(	const struct ly_ctx *	ctx,
		const char *	path
	)

Configure server based on the given data stored in a file.

Wrapper around nc_server_config_setup_data() hiding work with parsing the data. Context must already have implemented the required modules, see nc_server_config_load_modules().

Parameters

[in]	ctx	libyang context.
[in]	path	Path to a file with ietf-netconf-server, ietf-keystore or ietf-truststore YANG data. This data must be valid. No node can have an operation attribute.

Returns: 0 on success, 1 on error.

		const char *	endpt_name,
		NC_TRANSPORT_IMPL	transport,

	)

Creates new YANG configuration data nodes for address and port.

Parameters

[in]	ctx	libyang context.

[in,out]	config	Configuration YANG data tree. If *config is NULL, it will be created. Otherwise the new YANG data will be added to the previous data and may override it.

Returns: 0 on success, non-zero otherwise.

int nc_server_config_del_endpt	(	const char *	endpt_name,
		struct lyd_node **	config
	)

Deletes an endpoint from the YANG data.

Parameters

A certificate can not exist without its asymmetric key, so you must create an asymmetric key with the same identifier you pass to this function.

		const char *	cert_name,
		struct lyd_node **	config
	)

Deletes a keystore's certificate from the YANG data.

Parameters

[in]	asym_key_name	Identifier of an existing asymmetric key pair.
[in]	cert_name	Optional identifier of a certificate to be deleted. If NULL, all of the certificates belonging to the asymmetric key pair will be deleted.
