Kukho izizathu ezininzi ezenza ukuba iphepha lewebhu lingalayishi ngempumelelo kwisiphequluli sakho. Ngamanye amaxesha ingxaki yinto yokuhambelana. Abaphuhlisi bewebhsayithi bangakhetha ngokungafanelekileyo ukusebenzisa iindlela zokubamba iinkcukacha ezingenayo i-browser zonke ezikwazi ukutolika. Unokukhangela olu hlobo lokukhupha ngokusebenzisa isiphequluli esithile ukuze uvakashele iwebhusayithi. Enye yezizathu zokuba kutheni ingcinga efanelekileyo yokugcina i- Safari , i- Firefox kunye ne-Chrome ziphequluli zewebhu.
Ukuba iphepha lithwala kwi-browser enye kodwa ayikho enye, uyazi ukuba yinkinga yokuhambelana.
Enye yezona zinto ezibangela ukuba i-web page ayiyi kulayishwa yinkqubo engalunganga okanye egcinwe kakuhle kwi- DNS (i-Domain Name Server) kwinkqubo yakho ye-ISP (uMboneleli weNkonzo ye-Intanethi). Abasebenzisi abaninzi be-intanethi banesistim se- DNS abanikwa kubo nge-ISP yabo. Ngamanye amaxesha oku kwenziwa ngokuzenzekelayo; maxa wambi i-ISP iya kukunika idilesi ye-Intanethi ye-DNS ukuze ungene ngesandla kwisethingi sakho senethiwekhi. Kukho nawuphi na, ingxaki ihlala ekupheleni kwe-ISP yoxhumano.
I-DNS yinkqubo evumela ukuba sisebenzise amagama awakhunjulwayo kwiiwebhusayithi (kunye nezinye iinkonzo ze-Intanethi), endaweni ye-adware ze-IP ezibhekiselwe kwiiwebhusayithi. Umzekelo, kulula kakhulu ukukhumbula i-www.about.com ngaphezu kwe-207.241.148.80, enye yeyona dilesi ye-IP yangempela ye-About.com. Ukuba inkqubo ye-DNS ineengxaki zokuguqula i-www.about.com kwidilesi efanelekileyo ye-IP, i-website ayiyi kuyilayisha.
Unokubona umyalezo wephutha, okanye inxalenye yewebhsayithi ingabonisa.
Oko akuthethi akukho nto ongayenza. Unokuqinisekisa ukuba inkqubo ye-DNS ye-ISP isebenza ngokuchanekileyo. Ukuba akunjalo (okanye nokuba kunjalo), ukuba unqwenela, ungatshintsha izicwangciso zakho zeDNS ukusebenzisa iseva ethe xaxa kuneyona i-ISP yakho icebisa.
Ukuvavanya i-DNS yakho
I-Mac OS inikezela iindlela ezahlukeneyo zokuvavanya kwaye uqinisekise ukuba inkqubo ye-DNS isebenza kuwe. Ndiza kukubonisa enye yezo ndlela.
- Ukuqalisa i-Terminal, efumaneka kwi-Applications / Utilities /.
- Thayipha okanye kopisha / unamathisele umyalelo olandelayo kwiwindow ye Terminal.
www.about.com
- Cinezela ukubuya okanye faka ukhiye emva kokufaka umgca ongentla.
Ukuba inkqubo ye-DNS ye-ISP isebenza, kufuneka ubone ezi zilandelayo mibini ebuyiswe kwisicelo seCominal :
www.about.com yi-alias ye-dynwwwonly.about.com. dynwwwonly.about.com idibanisa 208.185.127.122
Yintoni ebalulekileyo umgca wesibini, oqinisekisa ukuba inkqubo ye-DNS yakwazi ukuguqulela igama lewebhu lewebhu kwidilesi ye-intanethi yenani, kule ngxaki 208.185.127.122. (nceda uqaphele: idilesi ye-IP ebuyisiwe ingahluka).
Zama umyalelo wokusingatha ukuba unengxaki yokufikelela kwiwebhusayithi. Ungakhathazeki malunga nenani leetekisi ezingabuyiselwa; ihlukahluka kwiwebsite ukuya kwiwebhusayithi. Yintoni ebalulekileyo kukuba awuboni umgca othi:
Jonga lakho.website.name ayifumanekanga
Ukuba ufumana i-website 'engayifumanekanga' isiphumo, kwaye unesiqiniseko sokungena ngokufanelekileyo igama lewebhu lewebhu (kunye nokuba kukho i-website ngelo gama), ngoko unokuqiniseka ngokuqinisekileyo ukuba, okwangomzuzu , inkqubo yakho ye-ISP ye-DNS ineengxaki.
Sebenzisa i-DNS eyahlukileyo
Indlela elula yokulungisa i-DP engasebenzi kakubi i-DNS kukufaka indawo ye- DNS eyahlukileyo kumnye onikeziwe. Enye ye-DNS inkqubo ehamba phambili iqhutywa yinkampani ebizwa ngokuba yi-OpenDNS (ngoku iyingxenye yeCisco), leyo inika inkululeko yokusetyenziswa kwenkqubo yayo ye-DNS. I-OpenDNS inikeza imiyalelo epheleleyo yokwenza utshintsho kwisimo somnatha we-Mac, kodwa ukuba unemiba ye-DNS, awukwazi ukufikelela kwiwebhsayithi ye-OpenDNS. Nantsi ukukhawuleza ngokukhawuleza kwendlela yokwenza utshintsho ngokwakho.
- Ukukhethwa kweNkqubo zoKhetho ngokuchofoza kwi-'Ifayile yezintandokazi zeNkqubo ' kwiDock , okanye ukhetha into' yeNdlela yokukhetha ' kwimenyu ye-Apple .
- Cofa iqhosha le 'Inethiwekhi' kwifestile yeNdlela yokukhetha.
- Khetha uxhumo osebenzisayo ukufikelela kwi-intanethi. Kuba phantse wonke umntu, oku kuya kuba yi-E-built-in Ethernet.
- Cofa iqhosha elithi 'Advanced'
- Khetha ithebhu 'DNS'.
- Cofa iqhosha (+) kunye nezantsi kwe-DNS Servers field kwaye faka idilesi elandelayo yeDNS.
208.67.222.222
- Phinda kwakhona amanyathelo angentla kwaye ufake idilesi yesibini ye-DNS, eboniswe ngezantsi.
208.67.220.220
- Cofa iqhosha elithi 'Kulungile'.
- Cofa iqhosha elithi 'Faka isicelo'.
- Vala ukhetho lweeNethiwekhi.
I-Mac yakho ngoku iyafikelela kwiinkonzo ze-DNS ezinikezelwe yi-OpenDNS, kwaye i-website ehambayo kufuneka ilayishe ngokufanelekileyo.
Le ndlela yokongeza i-OpenDNS yokungena igcina ixabiso le-DNS yakho yangaphambili. Ukuba unqwenela, ungahlaziya kwakhona uluhlu, ukuhambisa oku kungeniswa okuphezulu kwoluhlu. Usesho lwe-DNS luqala ngeseva yokuqala ye-DNS kuloluhlu. Ukuba isayithi ayitholakali kokungena kokuqala, i-DNS lookup ifowuni ifowuni yokungena. Oku kuyaqhubeka kude kubekwe ukukhangela, okanye zonke iinkonzo ze-DNS kuloluhlu ziphelile.
Ukuba iinkonzo ezintsha zeDNS ozifakayo zenza ngcono kangangoko zakho zangaphambili, unokuhambisa uncedo olutsha phezulu kwoluhlu ngokukhetha nje enye kwaye uyihudulele phezulu.
