Secondary (dns-server.Dns_server.Secondary)

type s

The state of a secondary DNS server.

val data : s -> Dns_trie.t

data s is the zone data of s.

val with_data : s -> Dns_trie.t -> s

with_data s trie is s with its data replaced by trie.

val create : 
  ?primary:Ipaddr.t ->
  tsig_verify:Dns.Tsig_op.verify ->
  tsig_sign:Dns.Tsig_op.sign ->
  rng:(int -> string) ->
  ('a Domain_name.t * Dns.Dnskey.t) list ->
  s

create ~primary ~tsig_verify ~tsig_sign ~rng keys creates a secondary DNS server state.

val handle_packet : 
  ?packet_callback:packet_callback ->
  s ->
  Ptime.t ->
  int64 ->
  Ipaddr.t ->
  Dns.Packet.t ->
  'a Domain_name.t option ->
  s * Dns.Packet.t option * (Ipaddr.t * string) option

handle_packet s now ts ip proto key t handles the incoming packet.

val handle_buf : 
  ?packet_callback:packet_callback ->
  s ->
  Ptime.t ->
  int64 ->
  Dns.proto ->
  Ipaddr.t ->
  string ->
  s * string option * (Ipaddr.t * string) option

handle_buf ~packet_callback s now ts proto src buf decodes buf, processes with handle_packet, and encodes the results.

val timer : s -> Ptime.t -> int64 -> s * (Ipaddr.t * string list) list

timer s now ts may request SOA or retransmit AXFR.

val closed : s -> Ptime.t -> int64 -> Ipaddr.t -> s * string list

closed s now ts ip marks ip as closed, the returned buffers (SOA requests) should be sent to ip.
