Kunezizathu eziningi zokuthi kungani ikhasi lewebhu lingase lilayishe ngempumelelo kusiphequluli sakho. Ngezinye izikhathi inkinga ingenye yokuhambisana. Abathuthukisi bewebhusayithi bangakhetha ngokungalungile ukusebenzisa amasu okubhala amakhemikhali akuzona zonke iziphequluli ezikwazi ukuzihumusha. Ungahlola lolu hlobo lokukhishwa ngokusebenzisa isiphequluli esihlukile ukuze uvakashele iwebhusayithi embuzweni. Lesi esinye sezizathu zokuthi kungani kungumqondo omuhle ukugcina iziphequluli zewebhu ze- Safari , Firefox , kanye ne-Chrome.
Uma ikhasi lilayisha kwisiphequluli esisodwa kodwa hhayi enye, uyazi ukuthi inkinga yokuhambelana.
Esinye sezimbangela ezinkulu zekhasi lewebhu elingalokothi lilayishwe uhlelo olungalungile noma olugcinwe kahle nge- DNS (Domain Name Server) uhlelo lwakho lwe-ISP (Umnikezeli Wesevisi Ye-Inthanethi). Abasebenzisi abaningi be-Inthanethi banesistimu ye- DNS eyabelwe yona nge-ISP yabo. Ngezinye izikhathi lokhu kwenziwa ngokuzenzakalelayo; ngezinye izikhathi i-ISP izokunika ikheli le-Inthanethi le-DNS yeseva ukuze ungene ngesandla kuzilungiselelo zenethiwekhi yakho. Kunoma yikuphi, inkinga ivame ekupheleni kuka-ISP kokuxhumeka.
I-DNS iyisistimu evumela ukuthi sisebenzise kalula amagama agciniwe amawebhusayithi (kanye namanye amasevisi e-Intanethi), kunokuba kube lula ukukhumbula amakheli we-IP amanani ayenziwe kumawebhusayithi. Isibonelo, kulula kakhulu ukukhumbula i-www.about.com kune-207.241.148.80, enye yekheli le-IP langempela le-About.com. Uma uhlelo lwe-DNS lunenkinga yokuhumusha i-www.about.com ekhelini elifanele le-IP, ngabe iwebhusayithi ngeke ilayishe.
Ungabona umyalezo wephutha, noma ingxenye kuphela yewebhusayithi ingabonisa.
Lokhu akusho ukuthi akukho lutho ongakwenza. Ungaqinisekisa ukuthi uhlelo lwakho lwe-DNS lwe-ISP lusebenza kahle. Uma kungenjalo (noma noma kunjalo), uma ufisa, ungashintsha izilungiselelo zakho ze-DNS ukuze usebenzise iseva enamandla kakhulu kunayo i-ISP yakho encoma ngayo.
Ukuhlola i-DNS yakho
I-Mac OS inikeza izindlela ezihlukahlukene zokuhlola nokuqinisekisa ukuthi uhlelo lwe-DNS olusebenzayo lungatholakala yini kuwe. Ngizokukhombisa enye yalezo zindlela.
- Qalisa i-Terminal, etholakala / Izicelo / Utilities /.
- Thayipha noma ukopishe / unamathisele umyalo olandelayo efasiteleni lokugcina.
thinta i-www.about.com
- Cindezela ukubuya noma faka ukhiye ngemuva kokufaka umugqa ngenhla.
Uma isistimu ye-DNS ye-ISP isebenza, kufanele ubone imigqa emibili elandelayo ibuyiselwe kwisicelo se-Terminal :
www.about.com yi-alias ye-dynwwwonly.about.com. i-dynwwwonly.about.com inesi-208.185.127.122
Okubalulekile yi-line yesibili, eqinisekisa ukuthi uhlelo lwe-DNS lwalukwazi ukuhumusha igama lewebhusaythi libe yileli kheli le-intanethi ye-intanethi, kulolu cala 208.185.127.122. (sicela uqaphele: ikheli langempela le-IP elibuyiselwe lingase lihluke).
Zama umyalo wokusingatha uma unenkinga yokufinyelela iwebhusayithi. Ungakhathazeki ngenani lemigqa yombhalo engabuyiselwa; kuhluka kusuka kuwebhusayithi kuya kuwebhusayithi. Okubalulekile ukuthi awuboni umugqa othi:
Hamba iwebhusayithi yakho.name ungatholakali
Uma uthola imiphumela 'ye-website engatholakali', futhi uqinisekile ukuthi ufake igama lewebhusayithi ngokunembile (futhi ukuthi kukhona iwebhusayithi ebizwa ngalelo gama), ungaqiniseka ngokuqinisekile ukuthi okungenani okwamanje , uhlelo lwakho lwe-DNS lwe-ISP lunenkinga.
Sebenzisa i-DNS ehlukile
Indlela elula yokulungisa i-DP engasebenzi kabi i-DNS ukufaka i- DNS ehlukile kulowo onikeziwe. Omunye uhlelo oluhle kakhulu lwe-DNS luqhutshwa yinkampani ebizwa i-OpenDNS (manje engxenyeni yeCisco), enikeza ukusetshenziswa mahhala kwesistimu ye-DNS. I-OpenDNS inikeza imiyalelo ephelele yokwenza izinguquko ekulungiseleleni kwenethiwekhi ye-Mac, kodwa uma unenkinga ye-DNS, ngeke ukwazi ukufinyelela iwebhusayithi ye-OpenDNS. Nasi isithuthuthu esisheshayo sokwenza izinguquko ngokwakho.
- Vula Izintandokazi Zesistimu ngokuchofoza isithonjana 'sezintandokazi zesistimu' ku-Dock , noma ukhethe into ethi 'Izintandokazi zesistimu' kusuka kwimenyu ye-Apple .
- Chofoza isithonjana 'senethiwekhi' kufasiteleni lokuthandayo leSistimu.
- Khetha uxhumano oyisebenzisayo ukufinyelela kwe-inthanethi. Kuzo cishe wonke umuntu, lokhu kuzokwakhiwa ku-Ethernet eyakhiwe.
- Chofoza inkinobho 'Okuthuthukisiwe'
- Khetha ithebhu 'DNS'.
- Chofoza inkinobho yokuhlanganisa (+) ngezansi kweseva ye-DNS bese ufaka ikheli le-DNS elilandelayo.
208.67.222.222
- Phinda izinyathelo ezingenhla bese ufaka ikheli lesibili le-DNS, eliboniswe ngezansi.
208.67.220.220
- Chofoza inkinobho ethi 'Kulungile'.
- Chofoza inkinobho ethi 'Faka isicelo'.
- Vala iphaneli lokuncamelayo yenethiwekhi.
I-Mac yakho manje izokwazi ukuthola amasevisi we-DNS anikezwe i-OpenDNS, futhi iwebhusayithi ehamba phambili kufanele ilayishe kahle.
Le ndlela yokwengeza okufakiwe kwe-OpenDNS igcina amanani wakho we-DNS wangempela. Uma ufisa, ungakwazi ukuhlela kabusha uhlu, ukuhambisa okufakiwe okusha phezulu ohlwini. Usesho lwe-DNS luqala nge-server yokuqala ye-DNS kuhlu. Uma isayithi ingatholakali ekungeneni kokuqala, i-DNS lookup imemeza kokungena kwesibili. Lokhu kuyaqhubeka kuze kube yilapho kuvele khona, noma wonke amaseva e-DNS ohlwini aphelile.
Uma amaseva amasha we-DNS owangezile enza ngcono kangcono ngakho-ke owokuqala, ungathutha okufakiwe okusha phezulu ohlwini ngokumane ukhethe eyodwa bese uyihudulela phezulu.
