Ukukhishwa kweseva ye-DNS egunyaziwe i-PowerDNS Authoritative Server 4.6, eyenzelwe ukuhlela ukulethwa kwezindawo ze-DNS, yakhululwa. Ngokwabathuthukisi bephrojekthi, i-PowerDNS Authoritative Server isebenzela cishe u-30% yenani eliphelele lezizinda e-Europe (uma sicabangela izizinda kuphela ezinamasiginesha e-DNSSEC, bese kuba ngu-90%). Ikhodi yephrojekthi isatshalaliswa ngaphansi kwelayisensi ye-GPLv2.
I-PowerDNS Authoritative Server inikeza amandla okugcina ulwazi lwesizinda kuzinqolobane ezihlukahlukene, okuhlanganisa i-MySQL, i-PostgreSQL, i-SQLite3, i-Oracle, ne-Microsoft SQL Server, kanye ne-LDAP namafayela ombhalo ongenalutho ngefomethi ye-BIND. Impendulo ingahlungwa ngokuqhubekayo (isibonelo, ukuhlunga ugaxekile) noma iqondiswe kabusha ngokuxhuma izibambi ngokwezifiso ku-Lua, Java, Perl, Python, Ruby, C kanye ne-C++. Izici futhi zihlanganisa amathuluzi okuqoqwa okukude kwezibalo, okuhlanganisa nge-SNMP noma nge-Web API (iseva ye-HTTP yakhelwe ukuze uthole izibalo nokuphathwa), ukuqalisa kabusha okusheshayo, injini eyakhelwe ngaphakathi yokuxhuma izibambi ngolimi lwesiLua, ikhono lokulayisha ibhalansi. kucatshangelwa indawo yendawo yeklayenti .
Okuqanjiwe okuyinhloko:
- Usekelo olungeziwe lwezihloko zephrothokholi ye-PROXY ezicelweni ezingenayo, okukuvumela ukuthi uqalise isilinganisi somthwalo phambi kweseva ye-PowerDNS kuyilapho usabika ulwazi lwekheli le-IP lamaklayenti axhumeka kusilinganisi somthwalo njenge-dnsdist.
- Ukwesekwa okwengeziwe kwe-EDNS Cookies mechanism (RFC 7873), ekuvumela ukuthi ubone ukulunga kwekheli le-IP ngokushintshaniswa kwe-Cookie phakathi kweseva ye-DNS kanye neklayenti ukuze uvikeleke ekuphangweni kwekheli le-IP, ukuhlaselwa kwe-DoS, ukusetshenziswa kwe-DNS njenge i-traffic amplifier kanye nemizamo ye-cache poisoning.
- Isixhumi esibonakalayo esisha sengeziwe kunsizakalo ye-pdnsutil kanye ne-API yokuphatha amaseva azimele, asetshenziselwa ukwenza ngokuzenzakalelayo ukuthunyelwa nokuvuselelwa kwezindawo kumaseva esibili e-DNS ngaphandle kokumisa izindawo zesibili mathupha. Kwanele ukuchaza indawo eyinhloko yesizinda esisha kuseva ye-autoprimary, futhi isizinda esisha sizothathwa ngokuzenzakalelayo amaseva esibili futhi silungiselele indawo yesibili kuso.
