An Authority that keeps itself updated by performing zone transfers.

Instance Variable primary The IP address of the server from which zone transfers will be attempted. (type: str)
Method __init__
Class Method fromServerAddressAndDomain Construct a new SecondaryAuthority from a tuple giving a server address and a bytes giving the name of a domain for which this is an authority.
Method transfer Undocumented
Method update Undocumented
Instance Variable _port The port number of the server from which zone transfers will be attempted.
Instance Variable _reactor The reactor to use to perform the zone transfers, or None to use the global reactor.
Method _lookup Determine a response to a particular DNS query.
Method _cbZone Undocumented
Method _ebZone Undocumented
Method _cbTransferred Undocumented
Method _ebTransferred Undocumented

Inherited from FileAuthority:

Instance Variable soa A 2-tuple containing the SOA domain name as a bytes and a dns.Record_SOA.
Method __setstate__ Undocumented
Method lookupZone Perform an AXFR record lookup.
Instance Variable _ADDITIONAL_PROCESSING_TYPES Record types for which additional processing will be done.
Instance Variable _ADDRESS_TYPES Record types which are useful for inclusion in the additional section generated during additional processing.
Method _additionalRecords Find locally known information that could be useful to the consumer of the response and construct appropriate records to include in the additional section of that response.
Method _cbAllRecords Undocumented

Inherited from ResolverBase (via FileAuthority):

Method lookupMailGroup Perform an MG record lookup.
Method lookupMailRename Perform an MR record lookup.
Method lookupPointer Perform a PTR record lookup.
Method lookupAuthority Perform an SOA record lookup.
Method lookupNull Perform a NULL record lookup.
Method lookupWellKnownServices Perform a WKS record lookup.
Method lookupService Perform an SRV record lookup.
Method lookupHostInfo Perform a HINFO record lookup.
Method lookupMailboxInfo Perform an MINFO record lookup.
Method lookupText Perform a TXT record lookup.
Method lookupSenderPolicy Perform a SPF record lookup.
Method lookupResponsibility Perform an RP record lookup.
Method lookupAFSDatabase Perform an AFSDB record lookup.
Method lookupNamingAuthorityPointer Perform a NAPTR record lookup.
Method lookupAllRecords Perform an ALL_RECORD lookup.
Method getHostByName Resolve the domain name name into an IP address.
Class Variable _errormap A dict mapping DNS protocol failure response codes to exception classes which will be used to represent those failures.
Method _cbRecords Undocumented
primary =
The IP address of the server from which zone transfers will be attempted. (type: str)
_port =
The port number of the server from which zone transfers will be attempted.
_reactor =
The reactor to use to perform the zone transfers, or None to use the global reactor.
def __init__(self, primaryIP, domain): (source)
ParametersdomainThe domain for which this will be the secondary authority. (type: bytes)
@classmethod
def fromServerAddressAndDomain(cls, serverAddress, domain): (source)

Construct a new SecondaryAuthority from a tuple giving a server address and a bytes giving the name of a domain for which this is an authority.

ParametersserverAddressA two-tuple, the first element of which is a str giving an IP address and the second element of which is a int giving a port number. Together, these define where zone transfers will be attempted from.
domainA bytes giving the domain to transfer.
ReturnsA new instance of SecondaryAuthority.
def transfer(self): (source)
Undocumented
def _lookup(self, name, cls, type, timeout=None): (source)

Determine a response to a particular DNS query.

ParametersnameThe name which is being queried and for which to lookup a response. (type: bytes)
clsThe class which is being queried. Only IN is implemented here and this value is presently disregarded. (type: int)
typeThe type of records being queried. See the types defined in twisted.names.dns. (type: int)
timeoutAll processing is done locally and a result is available immediately, so the timeout value is ignored.
ReturnsA Deferred that fires with a tuple of three sets of response records (to comprise the answer, authority, and additional sections of a DNS response) or with a Failure if there is a problem processing the query.
