kutulutsidwa kwa seva yovomerezeka ya DNS , yokonzedwa kuti ikonzekere kugawa magawo a DNS. Wolemba opanga mapulojekiti, PowerDNS Authoritative Server imagwira pafupifupi 30% ya madera onse ku Europe (ngati tingoganizira madera omwe ali ndi siginecha za DNSSEC, ndiye 90%). Project kodi zololedwa pansi pa GPLv2.
PowerDNS Authoritative Server imapereka mwayi wosunga zidziwitso za domain m'malo osiyanasiyana, kuphatikiza MySQL, PostgreSQL, SQLite3, Oracle, ndi Microsoft SQL Server, komanso mu LDAP ndi mafayilo osavuta amtundu wa BIND. Kubweza kwa yankho kumatha kusefedwanso (mwachitsanzo, kusefa sipamu) kapena kutumizidwanso polumikiza othandizira anu ku Lua, Java, Perl, Python, Ruby, C ndi C ++. Zina mwazinthuzi, palinso zida zosonkhanitsira ziwerengero zakutali, kuphatikiza kudzera pa SNMP kapena pa Webusayiti API (seva ya http imapangidwira ziwerengero ndi kasamalidwe), kuyambitsanso pompopompo, injini yolumikizidwa yolumikizira othandizira muchilankhulo cha Lua. , kutha kulinganiza katundu malinga ndi malo omwe kasitomala ali .
waukulu :
- Mbali yowonjezera zolemba ndi ogwira ntchito m'chinenero cha Lua, mothandizidwa ndi zomwe mungapangire otsogolera apamwamba omwe amaganizira za AS, subnets, kuyandikira kwa wogwiritsa ntchito, ndi zina zotero pobwezera deta. Thandizo la zolemba za Lua lakhazikitsidwa pazosungira zonse zosungirako, kuphatikiza BIND ndi LMDB. Mwachitsanzo, kuti mutumize deta poganizira za cheke chakumbuyo cha kupezeka kwa wolandila pamasinthidwe a zone, mutha kufotokoza:
@IN LUA A "ifportup(443, {'52.48.64.3', '45.55.10.200'})"
- Adawonjezera chida chatsopano , zomwe zimakulolani kusamutsa madera kuchokera ku seva yovomerezeka pogwiritsa ntchito zopempha za AXFR ndi IXFR, poganizira kufunikira kwa deta yomwe yasamutsidwa (pa dera lililonse, nambala ya SOA imafufuzidwa ndipo matembenuzidwe atsopano a chigawocho amatsitsidwa). Zomwe zimagwiritsidwa ntchito zimakupatsani mwayi wokonza zolumikizana ndi zigawo pamagulu ambiri achiwiri ndi obwereza osapanga katundu wolemetsa pa seva yoyamba;
- Pokonzekera zoyambira Mtengo wa udp-truncation-threshold parameter, womwe uli ndi udindo wochepetsera mayankho a UDP kwa kasitomala, wachepetsedwa kuchokera ku 1680 mpaka 1232, zomwe ziyenera kuchepetsa kwambiri mwayi wotaya mapaketi a UDP. Mtengo wa 1232 unasankhidwa chifukwa ndipamwamba kwambiri pomwe kukula kwa yankho la DNS, poganizira IPv6, kumagwirizana ndi chiwerengero chochepa cha MTU (1280);
- Yawonjezeranso chosungira chatsopano chochokera ku database . Kumbuyo kumagwirizana kwathunthu ndi DNSSEC, chitha kugwiritsidwa ntchito ngati madera ambuye ndi akapolo, ndipo imapereka magwiridwe antchito bwino kuposa ma backends ena ambiri. Atangotulutsidwa kumene, kusintha kunawonjezedwa ku code yomwe inasokoneza ntchito ya LMDB backend (kukonza zone za akapolo ndikutsitsa kudzera pa pdnsutil ntchito, koma malamulo monga "pdnsutil edit-zone" anasiya kugwira ntchito. Mavuto akukonzekera kuti athetsedwe. mu kumasulidwa koyenera kotsatira;
- Anasiya kuthandizira kwa "autoserial" yosalembedwa bwino, zomwe zimalepheretsa kuti nkhani zina zithetsedwe. Malinga ndi zofunikira (GOST R 34.11-2012 idasamukira ku gulu la "SAYENERA") DNSSEC sichirikizanso ma hashes a GOST DS ndi ma signature a digito a ECC-GOST.
Monga chikumbutso, PowerDNS yasamukira ku chitukuko cha miyezi isanu ndi umodzi, ndikutulutsa kotsatira kwa PowerDNS Authoritative Server kuyembekezeka mu February 2020. Zosintha pazotulutsa zazikulu zidzapangidwa chaka chonse, pambuyo pake zosintha zosatetezeka zidzatulutsidwa kwa miyezi ina isanu ndi umodzi. Chifukwa chake, kuthandizira kwa nthambi ya PowerDNS Authoritative Server 4.2 kupitilira mpaka Januware 2021.
