Cishe ingxenye yethrafikhi yokususa amaseva e-DNS ibangelwa umsebenzi we-Chromium

Umbhalisi we-APNIC, obhekele ukusatshalaliswa kwamakheli e-IP esifundeni sase-Asia-Pacific, eshicilelwe imiphumela yokuhlaziywa kokusatshalaliswa kwethrafikhi kwenye yezimpande zeseva ye-DNS a.root-servers.net. U-45.80% wezicelo kuseva eyimpande bezihlobene nokuhlola okwenziwa iziphequluli ngokusekelwe kunjini ye-Chromium. Ngakho-ke, cishe uhhafu wezisetshenziswa zamaseva we-DNS wempande usetshenziswa kusetshenziswa ukuhlolwa kokuxilonga kwe-Chromium kunokucubungula izicelo ezivela kumaseva e-DNS ukuze kutholwe izindawo eziyizimpande. Uma kubhekwa ukuthi i-Chrome ibala u-70% wemakethe yesiphequluli sewebhu, umsebenzi onjalo wokuxilonga uholela cishe kuzicelo eziyizigidi eziyizinkulungwane ezingama-60 ezithunyelwa kumaseva ayizimpande ngosuku.

Ukuhlola kokuxilonga kusetshenziswa ku-Chromium ukuze kutholwe ukuthi abahlinzeki besevisi basebenzisa amasevisi aqondisa kabusha izicelo kumagama angekho kuzibambi zabo. Amasistimu afanayo asetshenziswa abanye abahlinzeki ukuze baqondise ithrafikhi kumagama esizinda afakwe ngephutha - njengomthetho, ezizindeni ezingekho, amakhasi aboniswa ngesixwayiso sephutha, anikeza uhlu lwamagama okungenzeka alungile, nokukhangisa. Ngaphezu kwalokho, umsebenzi onjalo ubhubhisa ngokuphelele ingqondo yokunquma abasingathi be-intranet esipheqululini.

Lapho ucubungula umbuzo wosesho ofakwe kubha yekheli, uma kufakwa igama elilodwa elingenawo amachashazi, isiphequluli kuqala ngiyazama nquma igama elinikeziwe ku-DNS, kucatshangwa ukuthi umsebenzisi uzama ukufinyelela isayithi le-intranethi kunethiwekhi yangaphakathi, kunokuba athumele umbuzo enjinini yokusesha. Uma umhlinzeki eqondisa kabusha imibuzo emagameni esizinda angekho, abasebenzisi banenkinga - noma yimiphi imibuzo yokusesha yegama elilodwa efakwe kubha yamakheli iqala ukuqondisa kabusha emakhasini omhlinzeki, kunokuba ithunyelwe enjinini yokusesha.

Ukuze uxazulule le nkinga, onjiniyela be-Chromium bangeze esipheqululini amasheke engeziwe, okuthi, uma ukuqondisa kabusha kutholwa, kuguqule ingqondo yokucubungula izicelo kubha yekheli.
Ngaso sonke isikhathi uma uvula, ushintsha izilungiselelo zakho ze-DNS, noma ushintsha ikheli lakho le-IP, isiphequluli sithumela izicelo ezintathu ze-DNS ezinamagama esizinda angahleliwe wezinga lokuqala okungenzeka awekho. Amagama ahlanganisa kusukela ku-7 kuya ku-15 izinhlamvu zesiLatini (ngaphandle kwamachashazi) futhi asetshenziselwa ukuthola ukuqondisa kabusha kwamagama wesizinda angekho ngumhlinzeki kumsingathi wawo. Uma, lapho kucutshungulwa izicelo ezintathu ze-HTTP ngamagama angahleliwe, ezimbili zithola ukuqondisa kabusha ekhasini elifanayo, khona-ke i-Chromium ibheka ukuthi umsebenzisi uqondiswe kabusha ekhasini lenkampani yangaphandle.

Osayizi besizinda abangajwayelekile bezinga lokuqala (kusuka kuzinhlamvu eziyi-7 kuye kweziyi-15) kanye nesici esiphindaphindwayo sombuzo (amagama akhiqizwa ngokungahleliwe isikhathi ngasinye futhi awaphindanga) asetshenziswe njengezimpawu zokuhlukanisa umsebenzi we-Chromium ekugelezeni okuvamile kwezicelo kumsuka weseva ye-DNS.
Kulogi, izicelo zezizinda ezingekho zihlungwe kuqala (78.09%), kwabe sekukhethwa izicelo eziphindaphindiwe izikhathi ezingaphezu kwezintathu (51.41%), kwase kuthi izizinda eziqukethe izinhlamvu ezisuka ku-7 kuye kweziyi-15 zihlungwa (45.80%). . Kuyathakazelisa ukuthi ama-21.91% kuphela wezicelo kumaseva ezimpande ayehlobene nencazelo yezizinda ezikhona.

Ucwaningo luphinde lwahlola ukuncika komthwalo okhulayo kumaseva ezimpande a.root-servers.net kanye ne-j.root-servers.net ekudumeni okukhulayo kwe-Chrome.

KuFirefox, i-DNS iqondisa kabusha amasheke zilinganiselwe ukuchaza ukuqondisa kabusha emakhasini okuqinisekisa (ingosi yabathunjwa) kanye kwenziwe с usebenzisa isizinda esingaphansi esilungisiwe “detectportal.firefox.com”, ngaphandle kokucela amagama esizinda sokuqala. Lokhu kuziphatha akudali umthwalo owengeziwe kumaseva ezimpande ze-DNS, kodwa kungenzeka kucatshangelwe njengokuputshuka kwedatha eyimfihlo emayelana nekheli le-IP lomsebenzisi (ikhasi elithi “detectportal.firefox.com/success.txt” liyacelwa isikhathi ngasinye lapho yethulwa). Ukuze ukhubaze ukuskena kuFirefox, kunesilungiselelo esithi “network.captive-portal-service.enabled”, esingashintshwa ekhasini elithi “mayelana:config”.
