Iseva yomdlalo efanayo isebenza kuphela nge-VPN: lokho kufakazelani
I-VPN ishintsha ikheli lomthombo, umzila futhi ngezinye izikhathi ukukhethwa kwendawo yokugcina. Bhala umsebenzi kanye nokwehluleka kokuqala ngaphambi kokusola umzila oqondile.
Iseva eyodwa, imizamo emibili: lapho i-VPN icishiwe iseshini iyawa ngesikhathi sokulayisha, lapho ivuliwe iseshini efanayo ijoyina. Lokho ubufakazi bangempela futhi kulula ukukufunda ngokweqile. Ukuvula i-VPN kushintsha ikheli lomthombo, umzila wokudlula, inqubomgomo yesixazululi futhi ngezinye izikhathi umndeni wamakheli ngasikhathi sinye, ngakho impumelelo ikutshela ukuthi umehluko wawubalulekile ngaphandle kokukutshela ukuthi wawuyiphi imehluko. Ukudlula ukuqhathanisa ungqimba olulodwa ngesikhathi iyona ndlela yokuthola impendulo ongayenza. Kubuye kukuvimbele ekushintsheni izinto ezine futhi ungafundi lutho.
Qinisekisa kuqala ukuthi umhlinzeki uhlose ini
Iseva yangasese edinga i-VPN egunyaziwe kufanele ingafinyeleleki ngoxhumano oluvamile lomphakathi, futhi lokho kuwukuhlelwa okusebenzayo hhayi iphutha. Iseva yomphakathi eshicilelwe ehluleka ngqo emzileni owodwa wokufinyelela iyisimo esihlukile esinomnikazi ohlukile. Ngaphambi kokuhlola noma yini, thola ukuthi yikuphi kwalokhu okubili okubhekile, ngoba impendulo inquma ukuthi ulungisa inethiwekhi noma ufunda inqubomgomo. Buza umhlinzeki, noma funda amanothi okufinyelela ashicilelwe, esikhundleni sokucabanga lokho ngokwehluleka kokujoyina.
Uma umhlinzeki eshicilela indlela yokufinyelela, yisebenzise. Ukugwema umkhawulo wamabomu akusiwona umsebenzi ofanayo nokulungisa umzila ophukile.
Gcina irekhodi lokuqhathanisa lincane futhi lizinze
Gcina umdlalo, i-akhawunti, iseva ekhethiwe kanye nomsebenzi kuzinzile phakathi kwemizamo, futhi shintsha isimo se-VPN kuphela. Bhala isihlonzi seseva nesifunda, kanye nekheli langempela lapho iklayenti likhombisa khona, ngoba igama leseva elibonakalayo akusilo elisetshenziswa inethiwekhi. „Isiqalisi sivulile“ kanye „le seshini yabadlali abaningi ijoyinile“ kuyimiphumela ehlukile, futhi ukuxuba kwayo kwenza ukuqhathanisa kube yize.
Bhala leyo migha emine ngaphambi kokuhlola kokuqala. Ukuqhathanisa okuwukwakha kabusha ngenkumbulo ngemuva kwalokho kuyindaba, hhayi isilinganiso.
Shono ukwehluleka kokuqala, hhayi umyalezo wokugcina
Umyalezo esikrinini uvame ukuba umcimbi wokugcina ochungechungeni. Qaphela owokuqala onengqondo esikhundleni salokho: ukuxazululwa kwegama, ukuphela kwesikhathi sokudlulisa, ukunqatshwa koxhumano, umkhawulo we-akhawunti noma iphutha leseshini ngemuva kokuphumelela koxhumano. Lezi zigaba zinabanikazi nezilungiso ezihlukile, futhi ibhena elijwayelekile „linqanyuliwe“ licindezela konke ezwini elilodwa elingelusizo.
Uma iklayenti ligcina ilogi, yifunde ngesigaba hhayi ngekhodi yephutha. Isigaba sikutshela ukuthi yiluphi ungqimba okufanele uluhlole ngokulandelayo.
Igama elifanayo alisho i-tuple efanayo
Igama lomsingathi lingaxazululeka libe amakheli ahlukile emizileni ehlukile, futhi i-IPv4 ne-IPv6 zingalandela imizila nemigomo ehluke ngokuphelele. Hlola ukuthi umzamo oqondile nomzamo we-VPN basebenzisa indawo efanayo nomndeni wamakheli ofanayo ngaphambi kokuqhathanisa imiphumela yawo. Uma kungenjalo uqhathanisa izivivinyo ezimbili futhi uzibiza eyodwa.
Ngomehluko womzila, khumbula ukuthi umzila we-inthanethi ulandela inqubomgomo yomhlinzeki hhayi umugqa omfushane kakhulu ngokwendawo, futhi yilowo mqondo ochazwe ku-isicaciso se-BGP. I-VPN egwema umzila wokudlula omubi ikhombisa ukuthi umzila wawumubi, hhayi ukuthi othile ukuvimbela ngamabomu.
Hlola ukudlulisa umdlalo okuwusebenzisayo ngempela
Ukuxhumana kwe-TCP okuphumelelayo embobeni eyodwa akusunguli iseshini ye-UDP, futhi akukho kukho kokubili okufakazela ukuthi ukungena kumdlalo kuqedile. Landela izinsizakalo umdlalo owudinga ngempela esikhundleni sohlu lwamachweba olukotshwe komunye umdlalo, futhi khetha ukubuka indlela yeklayenti ngokwalo kunokuhlola ngaphandle. Uma iseva iphendula isicelo esivela ekhelini lakho lokuphuma ngokunqaba, lowo umbuzo wenqubomgomo kumhlinzeki, hhayi ubufakazi mayelana nekhebula lakho noma irawutha yasekhaya.
Ngokumkhawulo ocacile sebenzisa isiteshi sokusekela noma sokudlulisa isikhalo somshicileli. Ukufihla ukufaneleka kwe-akhawunti kungenye into eneminye imiphumela.
Uma ukubhala lokhu, faka imizila yomibili, umsebenzi ongashintshwanga, iseva nomndeni wamakheli okukhethiwe, kanye nokwehluleka kokuqala. Lona umbiko umhlinzeki angawuphenya, futhi awudingi ukushintsha izilungiselelo ezine ngasikhathi sinye ukuze uwukhiqize.
