Mwepụta nke caching sava DNS PowerDNS Recursor 4.6.0

Mwepụta nke sava DNS caching PowerDNS Recursor 4.6 dị, nke na-ahụ maka mkpebi aha na-emegharị emegharị. A na-ewu PowerDNS Recursor n'otu ntọala koodu dị ka PowerDNS Authoritative Server, mana PowerDNS recursive na ikike sava DNS na-emepụta site na usoro mmepe dị iche iche ma wepụta ya dị ka ngwaahịa dị iche iche. A na-ekesa koodu ọrụ n'okpuru ikikere GPLv2.

Ihe nkesa na-enye ngwaọrụ maka nchịkọta ndekọ ọnụ ọgụgụ dịpụrụ adịpụ, na-akwado ịmalitegharị ngwa ngwa, nwere injin arụnyere maka ijikọ njikwa n'asụsụ Lua, na-akwado DNSSEC, DNS64, RPZ ( Mpaghara Amụma nzaghachi), ma na-enye gị ohere ijikọ ndị na-edebanye aha ojii. Enwere ike ịdekọ nsonaazụ mkpebi dị ka faịlụ mpaghara BIND. Iji hụ na arụmọrụ dị elu, a na-eji usoro multixing njikọ ọgbara ọhụrụ na FreeBSD, Linux na Solaris (kqueue, epoll, / dev/poll), yana ngwugwu DNS dị elu nke nwere ike ịhazi iri puku kwuru iri puku arịrịọ yiri ya.

Na ụdị ọhụrụ:

  • Agbakwunyere ọrụ " Mpaghara na Cache ", nke na-enye gị ohere iweghachite mpaghara DNS oge ụfọdụ wee tinye ọdịnaya ya na cache, nke mere na cache na-adị mgbe niile na ọnọdụ "ọkụ" ma nwee data metụtara mpaghara ahụ. Enwere ike iji ọrụ ahụ na ụdị mpaghara ọ bụla, gụnyere mgbọrọgwụ. Enwere ike ime iweghachi mpaghara site na iji DNS AXFR, HTTP, HTTPS, ma ọ bụ site na nbudata site na faịlụ mpaghara.
  • Ọ ga-ekwe omume ịtọgharịa ndenye sitere na cache mgbe nnata nke arịrịọ ngosi mbata.
  • Nkwado agbakwunyere maka izochi oku na sava DNS site na iji DoT (DNS n'elu TLS). Site na ndabara, a na-enyere DoT aka mgbe ị depụtara ọdụ ụgbọ mmiri 853 maka onye na-ebugharị DNS ma ọ bụ mgbe ị depụtara sava DNS n'ụzọ doro anya site na akara ntụpọ-to-auth-names. Emebebeghị nkwenye asambodo, dị ka ọ na-agbanwe na DoT na akpaghị aka yana nkwado ya site na sava DNS (a ga-eme atụmatụ ndị a ka ndị kọmiti ọkọlọtọ kwadochara ya).
  • Edegharịrị koodu maka ịtọlite ​​njikọ TCP na-apụ apụ, agbakwunyela ikike ijikwa njikọ ọzọ. Iji jikwaa njikọ TCP (na DoT), njikọ anaghịzi emechi ozugbo emechara arịrịọ, mana a na-ahapụ ya ka oghe ruo oge ụfọdụ (usoro tcp-out-max-idle-ms na-achịkwa omume ahụ).
  • Mgbasawanye nke metrik anakọtara na mbupụ nwere ọnụ ọgụgụ na ozi maka sistemụ nleba anya.
  • Agbakwunyere njirimara ịchụso ihe omume na-enye gị ohere ịnweta ozi zuru ezu gbasara oge mmezu nke ọkwa mkpebi ọ bụla.
