Expand description
Response codes for transaction authentication (TSIG).
TSIG and TKEY resource records contain a 16 bit wide error field whose
values are an extension of the standard DNS Rcode
. While it was
intended to also share the same space with the extended response codes
used by EDNS (see OptRcode
), both used the value 16. To allow
distinguish between the two uses of this value, we have two separate
types.
The values for all three response code types are defined in the IANA DNS RCODEs registry. This type is complete as of 2019-01-28.
Variants§
NoError
FormErr
ServFail
Server failure.
The name server was unable to process this query due to a problem with the name server.
Defined in RFC 1035.
NXDomain
Name error.
The domain name given in the query does not exist at the name server.
Defined in RFC 1035.
NotImp
Refused
Query refused.
The name server refused to perform the operation requested by the query for policy reasons.
Defined in RFC 1035.
YXDomain
Name exists when it should not.
Returned for an UPDATE query when a domain requested to not exist does in fact exist.
Returned when resolving a DNAME redirection when the resulting name exceeds the length of 255 octets.
Defined in RFC 2136 for the UPDATE query and RFC 6672 for DNAME redirection.
YXRRSet
RR set exists when it should not.
Returned for an UPDATE query when an RRset requested to not exist does in fact exist.
Defined in RFC 2136.
NXRRSet
RR set that should exist does not.
Returned for an UPDATE query when an RRset requested to exist does not.
Defined in RFC 2136.
NotAuth
Server not authoritative for zone or client not authorized.
Returned for an UPDATE query when the server is not an authoritative name server for the requested domain.
Returned for queries using TSIG when authorisation failed.
NotZone
Name not contained in zone.
A name used in the prerequisite or update section is not within the zone given in the zone section.
Defined in RFC 2136.
BadSig
BadKey
Key not recognized.
The server did not recognize the key used for generating the signature.
Defined in RFC 2845.
BadTime
Signature out of time window.
The server time was outside the time interval specified by the request.
Defined in RFC 2845.
BadMode
Bad TKEY mode.
The mode field in a TKEY resource record contained a mode not supported by the server.
Defined in RFC 2930.
BadName
Duplicate key name.
In TKEY records, when establishing a new key, the name used already exists at the server or when deleting a key, a key of this name does not exist.
Defined in RFC 2930.
BadAlg
Algorithm not supported.
The value is defined in RFC 2930 but never actually explained. Presumably, it will be returned when the algorithm field of a TKEY record contains a value not supported by the server.
BadTrunc
Bad truncation.
A TSIG record was received with a MAC too short for the local policy in force.
Defined in RFC 4635.
BadCookie
Bad or missing server cookie.
The request contained a COOKIE option either without a server cookie or with a server cookie that did not validate.
Defined in RFC 7873.
Int(u16)
A raw value given through its integer.
Implementations§
source§impl TsigRcode
impl TsigRcode
sourcepub fn from_mnemonic(m: &[u8]) -> Option<Self>
pub fn from_mnemonic(m: &[u8]) -> Option<Self>
Returns a value from a well-defined mnemonic.
sourcepub const fn to_mnemonic(self) -> Option<&'static [u8]>
pub const fn to_mnemonic(self) -> Option<&'static [u8]>
Returns the mnemonic for this value if there is one.
This will also return a mnemonic if a well-defined variant
is hidden in a Int
variant.
pub fn parse<'a, Octs: AsRef<[u8]> + ?Sized>( parser: &mut Parser<'a, Octs> ) -> Result<Self, ParseError>
pub const COMPOSE_LEN: u16 = 2u16
pub fn compose<Target: OctetsBuilder + ?Sized>( &self, target: &mut Target ) -> Result<(), Target::AppendError>
