Isku xidhka Cusboonaysiinta Serverka DNS 9.11.18, 9.16.2 iyo 9.17.1

La daabacay Cusboonaysiinta saxda ah ee laamaha xasilloon ee BIND DNS server 9.11.18 iyo 9.16.2, iyo sidoo kale laanta tijaabada 9.17.1, taas oo ku jirta horumarka. Siidaynta cusub meesha laga saaray dhibaatada amniga ee la xiriirta difaac la'aanta weerarrada"Dib-u-habaynta DNS» markaad ku shaqaynayso qaabka codsiyada gudbinta ee server-ka DNS ("hormarinta" block in settings). Intaa waxaa dheer, shaqo ayaa la sameeyay si loo dhimo cabbirka tirakoobka saxeexa dhijitaalka ah ee lagu kaydiyo xusuusta DNSSEC - tirada furayaasha la raad raaco ayaa hoos loo dhigay 4 aag kasta, taas oo ku filan 99% kiisaska.

Farsamada "dib-u-celinta DNS" waxay u oggolaaneysaa, marka isticmaaluhu uu furo bog gaar ah browser-ka, si loo dhiso xiriirka WebSocket ee adeegga shabakadda ee shabakadda gudaha ee aan si toos ah looga heli karin internetka. Si aad uga gudubto ilaalinta loo isticmaalo daalacashada ka dhanka ah in laga gudbo baaxadda domain-ka hadda (iskutallaabta-asalka), beddel magaca martida loo yahay ee DNS. Adeegga DNS-ka ee weeraryahanku waxa loo habeeyey inuu mid mid u soo diro laba ciwaan oo IP ah: codsiga ugu horreeya wuxuu soo dirayaa IP-ga dhabta ah ee server-ka bogga, codsiyada xigana waxay soo celiyaan ciwaanka gudaha ee aaladda (tusaale, 192.168.10.1).

Waqtiga lagu noolaan karo (TTL) ee jawaabta ugu horreysa ayaa lagu dejiyay qiimaha ugu yar, marka marka la furayo bogga, browser-ku wuxuu go'aamiyaa IP-ga dhabta ah ee server-ka weerarka wuxuuna ku shubaa waxa ku jira bogga. Boggu wuxuu maamulaa koodka JavaScript kaas oo sugaya TTL inuu dhaco oo soo diraya codsi labaad, kaas oo hadda u aqoonsan martigeliyaha 192.168.10.1. Tani waxay u oggolaaneysaa JavaScript inuu galo adeegga gudaha shabakadda maxalliga ah, isagoo ka gudbaya xaddidaadda asalka ah. ilaalinta ka dhanka ah weerarrada noocaan ah ee BIND waxay ku saleysan tahay in laga joojiyo server-yada dibadda inay soo celiyaan ciwaannada IP-ga ee shabakadda gudaha ee hadda jirta ama magacyadooda CNAME ee xayndaabka maxalliga ah iyadoo la adeegsanayo cinwaannada diidmada-jawaab-celinta iyo dejinta-jawaab-jawaab-jawaab.
