Squid 5–7: kungani i-dns_v4_first ingasasebenzi
Ichaza ukususwa kwe-dns_v4_first ku-Squid 5 kuya ku-7 futhi yehlukanisa ukuthanda ikheli nokuphoqelela i-IPv4 kuphela.
Ukuhlelwa kwe-Squid kwakudala kuqukethe dns_v4_first on. Ngemuva kokuthuthukisa, lowo mugqa awusanikezi ukuthanda i-IPv4 obekulindelekile. Ukwengeza amanye amakhophi ngeke kubuyisele indlela yangaphambilini.
Incwadi yokuhlelwa ibala lo myalo njengongatholakali ku-Squid 5 kuya ku-7. Ukukhetha ikheli kwe-Squid kwashintsha nomsebenzi we-Happy Eyeballs; izeluleko zakudala zokuthanda kufanele zifundwe kuleso simo sokukhishwa.
Ukuthanda nokuphoqelela yizicelo ezimbili ezihlukene
Qala ngokunquma ukuthi udinga ini. Ukuthanda umzila we-IPv4 osebenzayo lapho imindeni yomibili ikhona? Ukususa ukuxhumana kwe-IPv6 okugqekeziwe? Ukuqinisekisa ukuthi okuphumayo okuthile kusebenzisa i-IPv4 kuphela? Lezi akuzona inqubomgomo eyodwa. Imikhawulo yomndeni wendawo okuya kuyo nayo kufanele ihlale yehlukile kuma-ACL omthombo weklayenti.
Ukukhulisa ukufinyelela emndenini owodwa kungenza amanye amasayithi angafinyeleleki. Ukushintsha izimpendulo ze-DNS kushintsha labo abangaba yiziphakamiso ezitholakala ku-proxy. Ukulungisa umzila onensayo noma ogqekeziwe kubhekana nokonakala kwenethiwekhi. Akukho kulokhu okufanele kuchazwe njengomugqa wokushintsha jikelele womyalo osusiwe.
Hlukanisa futhi ukukhethwa kwekheli lendawo okuya kuyo nekheli elisetshenziselwa ukufinyelela ku-proxy engumzali. Igama lomsingathi ongumzali lingaba neziphakamiso zalo ze-IPv4 ne-IPv6, kuyilapho umzali wenza ukuxhumana kokugcina kwesayithi ngokwenqubomgomo yakhe.
Umthetho wekheli lomthombo unenye indima: ukhetha umthombo ohambisana nokuxhumana, esikhundleni sokwakha ukusekelwa kwendawo okuya kuyo. Umthombo we-IPv4 awenzi indawo okuya kuyo ye-IPv6 kuphela ibe yindawo yokugcina ye-IPv4.
Hlola imibhalo yokukhishwa okufakiwe kanye nomzila wonke wokudlulisela. Uma inkinga iwukuxhumana kwe-IPv6 okungathembekile, gcina lokho kuxilonga esikhundleni sokwenza ushintsho lomhlaba wonke oluthule olukufihla nje. Umzila othandwayo osebenzayo nokuphuma okuqinile komndeni owodwa kufanele kube nokuhlela okuhlukene.
