Squid Split DNS: qondisa izizinda eziyimfihlo nge-resolver efanele

Ukubeka i-resolver yangaphakathi kuqala kanye ne-resolver yomphakathi kwesibili akutshelanga i-Squid ukuthi yimaphi amagama asesikhaleni samagama ngasinye.

Ku-Squid 6 kanye no-7, dns_nameservers sithatha indawo yohlu lwamarizolveva ajwayelekile ngamakheli eseva. Isintakisi yaso ayinakho ukuhlangana ngokwesizinda ngasinye. Impendulo engeyinhle evumelekile nayo yehlukile kwi-resolver engafinyeleleki, ngakho ezinye izindlela azisona isu elithembekile lokucinga izindawo zamagama ezingahambisani.

Qondisa imibuzo ngokwesizinda

Isidlulisimibuzo se-DNS sasendaweni singaveza umgomo ongakho. Kusesetho esikhona se-dnsmasq, isijobelelo esiyimfihlo singaqondiswa kanje:

server=/internal.example/192.0.2.53

Shintsha isizinda nekheli. Lungiselela i-upstream ezenzakalelayo egunyaziwe yamanye amagama, umlaleli ofanele kanye nemikhawulo yokufinyelela. Bese ukhombisa i-Squid kuleyo resolver ngokusetha okusekelwa inguqulo efakiwe.

Ngenye indlela, sebenzisa insizakalo ye-DNS yenhlangano exazulula zombili izindawo zamagama ngendlela efanele. Gwema ukubuyela emuva komphakathi okudalula amagama ayimfihlo ngaphandle kokukwazi ukuwaphendula.

Uma i-proxy engumzali yenza ukusesha kwendawo, leyo nyathelo idinga indawo yamagama ayimfihlo. I-resolver ekulo mkhathi we-Squid wasendaweni ngeke ilungise ukusesha komzali.

Hlola nesimo esingesihle

Khetha igama eliyimfihlo elivumelekile, igama lomphakathi elivumelekile negama eliyimfihlo elingekho. Kulelo nalelo, khomba i-upstream ehlosiwe kanye nokuthi impendulo elindelekile ikheli noma impendulo engesihle. Isimo sokugcina siveza ukubuyela emuva komphakathi ngengozi ngemva kwempendulo engesihle yangaphakathi.

Faka imindeni yamakheli edingwa iklayenti. Ukusesha kwe-A okusebenzayo akufakazi ukuthi i-AAAA ilandela umgomo noma ibuyisela indawo efinyelelekayo. Qaphela nesimo se-cache: impendulo egciniwe ingafihla ukuthi i-upstream iphi umbuzo omusha ongayikhetha.
