I-PowerDNS iseva yomthombo we-DNS evulekile

I-PowerDNS iseva ye-DNS ene-database (ngaphakathi kwalo isekela imininingwane ehlukahlukene, kufaka phakathi i-MySQL, i-PostgreSQL, i-SQLite3, i-Oracle ne-Microsoft SQL Server, kanye ne-LDAP) namafayela ombhalo asobala ngefomethi ye-BIND, njenge-backend okwenza kube lula ukuphatha inani elikhulu lokufakiwe kwe-DNS.

Impendulo ithi ingahlunga ngokungeziwe (ngokwesibonelo, ukuhlunga ugaxekile) noma ukuqondisa kabusha ukuxhuma abashayeli bakho eLua, Java, Perl, Python, Ruby, C no-C ++. Phakathi kwezici, imali inikezwa nokuqoqwa kwezibalo okude, kufaka phakathi nge-SNMP noma nge-web API (i-http server yakhelwe izibalo nokuphathwa), ukuqala kabusha okusheshayo, injini eyakhelwe ngaphakathi ukuxhuma abashayeli ngolimi I-Lua, ikhono lokulinganisela umthwalo ngokususelwa endaweni yekhasimende.

Abathuthukisi ngaphambilini banqume ukushicilela ngokwehlukana izingxenye ezimbili ezakha i-PowerDNS, iseva ephindaphindayo futhi enegunya, ukuze bakhiphe uhlobo olusha ngokushesha futhi ikakhulukazi, ngokusho konjiniyela.

Futhi kuhle, ezinsukwini ezimbalwa ezedlule onjiniyela bakhiphe inguqulo entsha yePowerDNS 4.2.0, inguqulo ngokusho konjiniyela bephrojekthi, esebenza cishe ama-30% enani eliphelele lezizinda eYurophu (uma sibheka izizinda kuphela ezinamasiginesha e-DNSSEC, bese kuba ngu-90%). Ikhodi yephrojekthi isatshalaliswa ngaphansi kwelayisense le-GPLv2 futhi kungathintwa kuyo kusuka ku- isixhumanisi esilandelayo.

Izici ezintsha eziyinhloko zePowerDNS 4.2.0

Ekumenyezelweni kwale nguqulo entsha yePowerDNS 4.2.0 ukwengezwa kwekhono lokuchaza amarejista nabalawuli ngolimi lwesiLua kuqokonyiswa, Ngalokho ungakha izilawuli eziyinkimbinkimbi ezibhekelela lapho uthumela idatha ye-AS, ama-subnet, ukusondela kumsebenzisi, njll.

Ukusekelwa kokugawulwa kwe-Lua kuyenziwa kukho konke ukubuyela emuva kwesitoreji, kufaka phakathi Bopha ne-LMDB. Isibonelo, ukubuyisa idatha kucatshangelwa isheke langemuva lokutholakala komsingathi kuzilungiselelo zendawo, manje ungacacisa:

@ IN LUA A "ifportup (443, {'52 .48.64.3 ', '45 .55.10.200'})"

Umbuso omusha ungeziwe ixfrdist, evumela ukuthi izindawo zidluliselwe kusuka kuseva egunyaziwe kusetshenziswa izicelo ze-AXFR ne-IXFR, Ngokucabangela ukubaluleka kwedatha edlulisiwe (kusizinda ngasinye, inombolo ye-SOA iqinisekisiwe futhi kulandwa izinhlobo ezintsha kuphela zendawo). I-utility ikwenza ukwazi ukuhlela ukuvumelanisa kwe-zone kunani elikhulu lamaseva wesibili naphindayo ngaphandle kokudala umthwalo omkhulu kuseva eyinhloko.

Ukulungiselela uhlelo lwefulegi lwango-2020 lwe-DNS, ipharamitha ye-udp-truncation-threshold, enesibopho sokunciphisa izimpendulo ze-UDP kwiklayenti, yehlisiwe kusukela ngo-1680 kuya ku-1232, okufanele inciphise kakhulu amathuba okulahleka kwephakethe UDP.

Inani elingu-1232 liyakhethwa, ngoba liyisilinganiso esiphezulu lapho usayizi wempendulo ye-DNS, kucatshangelwa i-IPv6, ivumelana nenani eliphansi le-MTU (1280);

Kungezwe i-backend yokugcina entsha ngokususelwa ku-database ye-LMDB.

I-backend ihambisana ngokuphelele ne-DNSSEC, ingasetshenziselwa izindawo eziyinkosi nezigqila, futhi inikeze ukusebenza okungcono kunezinye eziningi ezingemuva.

Ukuyeka ukuxhaswa kwesici se- "autoserial" esingabhalwanga kahle, okuvimbele ezinye izingqinamba ukuthi zingalungiswa.

Ngokuya ngezidingo ze-RFC 8624 (i-GOST R 34.11-2012 idluliselwe esigabeni esithi "AKUFANELE"), ukusekelwa kwe-DNSSEC kumisiwe kwe-GOST DS hashes kanye ne-ECC-GOST digital signatures.

IPowerDNS yenze ushintsho kumjikelezo wezinyanga eziyisithupha wokuthuthuka, kulindeleke ukuthi inguqulo elandelayo ebalulekile yePowerDNS kulindeleke ukuthi ikhishwe ngoFebhuwari 2020.

Ukuvuselelwa kokukhishwa okukhulu kuzokwenziwa unyaka wonke, ngemuva kwalokho kuzokhishwa ezinye izindlela zokuba sengozini kwezinye izinyanga eziyisithupha. Ngakho-ke, ukwesekwa kwegatsha leseva eligunyaziwe le-PowerDNS 4.2 kuzohlala kuze kube nguJanuwari 2021.

Kulabo abanentshisekelo yokuhlola le seva ye-DNS, ungalanda futhi ulandele imiyalo yokwakha kusuka ku- isixhumanisi esilandelayo.

Bangathola futhi isikhombimsebenzisi sokuphatha sale seva kunethiwekhi.
