Detailed Description

Convenience container for conveying DDNS behavioral parameters It is intended to be created per Packet exchange using the selected subnet passed into functions that require them.

Definition at line 46 of file srv_config.h.

Constructor & Destructor Documentation

isc::dhcp::DdnsParams::DdnsParams ( )

inline

Default constructor.

Definition at line 49 of file srv_config.h.

isc::dhcp::DdnsParams::DdnsParams	(	const Subnet4Ptr &	subnet,
		bool	d2_client_enabled
	)

inline

Constructor for DHPCv4 subnets.

Parameters

subnet	Pointer to Subnet4 instance to use for fetching parameter values (typically this is the selected subnet).
d2_client_enabled	flag which indicates whether or not D2Client is enabled (typically the value should come from global D2Client configuration).

Definition at line 58 of file srv_config.h.

isc::dhcp::DdnsParams::DdnsParams	(	const Subnet6Ptr &	subnet,
		bool	d2_client_enabled
	)

inline

Constructor for DHPCv6 subnets.

Parameters

subnet	Pointer to Subnet6 instance to use for fetching parameter values (typically this is the selected subnet).
d2_client_enabled	flag which indicates whether or not D2Client is enabled (typically the value should come from global D2Client configuration).

Definition at line 69 of file srv_config.h.

Member Function Documentation

bool isc::dhcp::DdnsParams::getEnableUpdates ( ) const

Returns whether or not DHCP DDNS updating is enabled.

The value is the logical AND of d2_client_enabled_ and the value returned by subnet_'s getDdnsSendUpdates(). It

Returns: True if updates are enabled, false otherwise or if subnet_ is empty.

Definition at line 901 of file srv_config.cc.

Referenced by isc::dhcp::D2ClientMgr::analyzeFqdn(), and isc::dhcp::Dhcpv4Srv::createNameChangeRequests().

std::string isc::dhcp::DdnsParams::getGeneratedPrefix ( ) const

Returns the Prefix Kea should use when generating domain-names.

Returns: The value from the subnet_ or an empty string if subnet_ is empty.

Definition at line 936 of file srv_config.cc.

Referenced by isc::dhcp::D2ClientMgr::generateFqdn().

std::string isc::dhcp::DdnsParams::getHostnameCharReplacement ( ) const

Returns the string to replace invalid characters when scrubbing hostnames.

Meaningful only if hostname_char_set_ is not empty.

Returns: The value from the subnet_ or an empty string if subnet_ is empty.

Definition at line 963 of file srv_config.cc.

std::string isc::dhcp::DdnsParams::getHostnameCharSet ( ) const

Returns the regular expression describing invalid characters for client hostnames.

If empty, host name scrubbing should not be done.

Returns: The value from the subnet_ or an empty string if subnet_ is empty.

Definition at line 954 of file srv_config.cc.

util::str::StringSanitizerPtr isc::dhcp::DdnsParams::getHostnameSanitizer ( ) const

Returns a regular expression string sanitizer.

If the value returned by getHostnameCharSet() is not empty, then it is used in conjunction the value returned by getHostnameCharReplacment() (which may be empty) to create and return a StringSanitizer instance. Otherwise it will return an empty pointer.

Returns: pointer to the StringSanitizer instance or an empty pointer

Exceptions

BadValue if the compilation fails.

bool isc::dhcp::DdnsParams::getOverrideClientUpdate ( ) const

Returns whether or not Kea should perform updates, even if client requested delegation.

Returns: The value from the subnet_ or false if subnet_ is empty.

bool isc::dhcp::DdnsParams::getOverrideNoUpdate ( ) const

Returns whether or not Kea should perform updates, even if client requested no updates.

std::string isc::dhcp::DdnsParams::getQualifyingSuffix ( ) const

Returns the suffix Kea should use when to qualify partial domain-names.

Returns: The value from the subnet_ or an empty string if subnet_ is empty.

D2ClientConfig::ReplaceClientNameMode isc::dhcp::DdnsParams::getReplaceClientNameMode ( ) const

Returns how Kea should handle the domain-name supplied by the client.

Returns: The value from the subnet_ or RCM_NEVER if subnet_ is empty.

Definition at line 927 of file srv_config.cc.

SubnetID isc::dhcp::DdnsParams::getSubnetId ( ) const

inline

Returns the subnet-id of the subnet associated with these parameters.

Returns: value of subnet-id (or 0 if no subnet is associated)

Definition at line 145 of file srv_config.h.

bool isc::dhcp::DdnsParams::getUpdateOnRenew ( ) const

Returns whether or not DNS should be updated when leases renew.

If this is true, DNS should always be updated when leases are extended (i.e. renewed/rebound) even if the DNS information has not changed.

Returns: True if updates should always be performed.

bool isc::dhcp::DdnsParams::getUseConflictResolution ( ) const

Returns whether or not keah-dhcp-ddns should use conflict resolution.

This value is communicated to D2 via the NCR. When true, D2 should follow follow conflict resolution steps described in RFC 4703. If not, it should simple add or remove entries.

Returns: True if conflict resolution should be used.
