Functions ¶

func CopyDNSClient ¶

func CopyDNSClient(dnsClient *dns.Client) (*dns.Client, error)

CopyDNSClient performs a deep copy of dnsClient, changing the network to TCP. If the existing network is configured to only use IPv4 or IPv6 then the appropriate network is chosen to maintain this choice.

func ExchangeTKEY ¶

func ExchangeTKEY(client Exchanger, host, keyname, algorithm string, mode uint16, lifetime uint32, input []byte, extra []dns.RR, tsigname, tsigalgo string) (*dns.TKEY, []dns.RR, error)

ExchangeTKEY exchanges TKEY records with the given host using the given key name, algorithm, mode, and lifetime with the provided input payload. Any additional DNS records are also sent and the exchange can be secured with TSIG if a key name, algorithm and MAC are provided. The TKEY record is returned along with any other DNS records in the response along with any error that occurred.

Types ¶

type Exchanger ¶

type Exchanger interface {
	Exchange(*dns.Msg, string) (*dns.Msg, time.Duration, error)
}

Exchanger is the interface a DNS client is expected to implement.
