Kungani amanye amawebhusayithi ehluleka kuphela uma i-VPN ivuliwe?

Uma isayithi eyodwa ihluleka kuyilapho ezinye zilayisha, lokho kunciphisa ngokushesha ububanzi bephutha. Funda iphutha, hlola ukuxazululwa kwamagama, bese uhlola usayizi wephakethe ngaphambi kokuthinta iklayenti.

Ukuthi isayithi eyodwa yehluleka kuyilapho konke okunye kulayisha kufakazela ukuthi umhubhe uthwala ithrafikhi, futhi lokho kunciphisa inkinga ngaphezu kwalokho abantu abaningi abakulindele. Ukubona okuthathu kuhlela okunye: ukuthi uthole impendulo ye-HTTP noma cha, ukuthi igama lomsingathi laxazululwa laba ikheli, nokuthi izicelo ezincane ziyadlula kuyilapho ezinkulu zimile. Ukuqagela nge-VPN ngaphambi kokuba ube nalezi zimpendulo ngokuvamile kuhambisa iphutha esikhundleni sokulixosha.

Sebenza ngokubona ngokulandelana, ngoba isayithi esiphendulile asikwazi ukwehluleka ngasikhathi sinye ekuxazululweni. Uma kungekho lutho olulayishayo, usegatsheni elingalungile, futhi kusebenza izihlolo zesimo sokuxhumekile kodwa ngaphandle kwe-inthanethi.

Vumela umlayezo wephutha ukuthi akhethe igatsha

Ukwenqatshwa, inselelo ye-bot noma ikhasi lephutha kusho ukuthi insiza iphendulile, okusho ukuthi amaphakethe afinyelele uhlelo lokusebenza futhi abuya. Lokho kuhambisa umbuzo kunqubomgomo yokufinyelela yesayithi, engase ilinganisele ikheli lokuphuma, i-akhawunti noma amaphethini ezicelo engawashicileli. Ukwehluleka kokuxazululwa kwamagama akuzange kufinyelele isayithi nhlobo, futhi ikheli yinto yokuqala okufanele ihlolwe. Isikhathi sokuphela siphakathi kwalokhu kokubili: kukhona okuthunyelwe futhi akukho okukuqinisekisile.

Izexwayiso zesitifiketi zisengatsheni yesine. Zisho ukuthi uxhumano lwaphendulwa yinto okwakungakwazi ukuhlola ubunikazi bayo, okungaba ummeleli ohlangothini lwakho noma ukungafani kwangempela okungafanele uqhwebe ngakho. Kuthatha njengombuzo wokwethenjwa, hhayi wokuhlela umzila.

Isayithi esiphendulayo asifakazelanga umhubhe ophukile

Uma impendulo iyikhasi lokuvimba, qhathanisa ikhasi elifanayo ngokuphuma kwesibili kuyilapho isiphequluli nomshini kungashintshwanga. Uma umphumela ulandela ikheli lokuphuma, isayithi siphatha lelo kheli ngendlela ehlukile, futhi akukho ukumiswa kweklayenti okuyokushintsha. Uma ukuvimba kulandela isiphequluli sakho, imbangela isekwengezwekile, kummeleli ogciniwe noma ekusetheni kwesixazululi. Imisebenzi emibili ihlukanisa lezi zincazelo ngokushibhile.

Ukwehluleka okwenzeka kuphela kusiphequluli kuvamile ngokwanele ukuba kuhlolwe kusenesikhathi. Ikhasi elilayisha kwesinye isiphequluli esisekelwayo futhi lehluleke kwesinye likhombisa isimo sephrofayili, isivimbi sokuqukethwe noma i-DNS ebethelwe emiswe ngaphakathi kwesiphequluli uqobo. Ukuqondiswa kwe-Chrome mayelana ne-DNS ephephile kukhombisa lapho kukhona leso setheni, futhi ukusishintsha ngokulawula okusekelwayo kungcono kunokusetha kabusha idivayisi.

Uma kumile kuphela ukudluliswa okukhulu, bheka usayizi wephakethe

Ikhasi elidweba isihloko salo bese lima linophawu oluhlukile kunekhasi elingaqali nhlobo. Izimpendulo ezincane zingadlula kuyilapho umthwalo ogcwele ususwa endaweni engakwazi ukuthumela isignali kumthumeli, futhi yilokho ukwehluleka kwe-MTU yendlela okubonakala ngakho kusiphequluli. Qhathanisa isicelo esincane kakhulu nesikhulu kumsingathi ofanayo ngaphambi kokuthi wenze ithiyori ngokuhlunga. Ukutholakala kwe-MTU yendlela kufanele kufunde usayizi wokuxhumana omncane kakhulu endleleni, futhi kuncike ekuphenduleni kwe-ICMP okuvamile ukuthi kukujikijelwe amanethiwekhi ahlungiwe.

Hlola leyo mqagelo ngokuskena kosayizi esikhundleni se-ping eyodwa. Ukwehluleka okuqala kusayizi womthwalo ongaguquki kuwubufakazi obuqinile, kuyilapho ukwehluleka okuzulazulayo kungenjalo.

Qinisekisa ukulungisa kusicelo esahlulekayo

Hlola kabusha umsebenzi wangempela, hhayi ikhasi lasekhaya, ngoba igobolondo eligciniwe lingadwetshwa kuyilapho ucingo lwe-API ngemuva kokungena lusahluleka. Imiyalo engezansi ihlukanisa ukuxazululwa kwamagama, isicelo esincane nesicelo esikhulu kumsingathi ofanayo. Shintsha igama lomsingathi nendlela ngezinto ezivela esicelweni esaphuke ngempela.

dig +short www.example.com

Uma impendulo ye-dig yehlukile kunaleya esetshenziswe isiphequluli, isixazululi siyinto eguqukayo, futhi ukusetha kwe-DNS kwesiphequluli uqobo yindawo okufanele ubheke kuyo. Uma isicelo esincane sibuyisa isimo kuyilapho esikhulu simile, sebenza egatsheni losayizi wephakethe. Uma kokubili kuphela isikhathi, indlela yokuphuma nendlela isayithi eliphatha ngayo lelo kheli ziphinde zibe setafuleni.

Gcina ushintsho olwenza isicelo sokuqala siphumelele futhi ubuyisele okunye. Inqwaba yezinguquko zesikhathi esisodwa kusiphequluli, kwisixazululi nakwiklienti ikushiya ungakwazi ukuthi yikuphi obekubalulekile.
