Ukunciphisa isikhathi se-DPD akusheshisi ukushintshwa kwe-VPN

Imigudu iyawa, ukubuyisela kuthatha amasekhondi angamashumi ayisishiyagalolunye, futhi isibali somlingani ofile sibekwe kwishumi, ngakho isibali siyagxekwa. Lokho kucabanga kweqa izigaba ezintathu ezenzeka ngemva kokutholwa futhi ngokuvamile ezithatha isikhathi esiningi. Ukutholwa kokuphila kubona ukuthula; bese kuthi ukukhethwa komlingani, ukuqinisekiswa, ukufakwa komgwaqo nokuxhunywa kabusha kohlelo kuthatha indawo ngayinye. Ukufinyeza isigaba sokuqala akukwazi ukufinyeza ezinye, futhi kungangeza isiphithiphithi ohlelweni olwalukhathazekile kakade.

Izigaba ezine, esisodwa sazo ongalinganisa isikhathi saso

Bhala ukubuyisela njengezehlakalo ezine ezinamamaki esikhathi. Ukwehluleka kuba yinto ebonakalayo: ithrafikhi yokugcina evikelekile ewusizo kanye nesicelo sokuqala esihlulekile. Umshini ongumnikazi uyasabela: ukutholwa kokuphila, umqaphi womgwaqo noma esinye isiqhumisi esibhaliwe. Enye indlela iyasebenza: ukukhethwa komlingani, ukuqinisekiswa, ukuhlangana okusha nomgwaqo ogqibelela ukuthwala ithrafikhi ehlosiwe. Uhlelo luyalulama: umsebenzi omusha uyaphumelela futhi lokho obekuqhubeka kunomphumela oqondile.

Imithetho yokuphila ye-IKEv2 ichaza ubufakazi ngomlingani nokushintshana kwakhe, futhi ayisho lutho ngesizindalwazi noma isevisi yamafayela ngemva kwalowo mlingani. Ukufunda ukuphela kwesikhathi sokuphila njengokuhlolwa kwezempilo komgwaqo wonke yiphutha eliqala ukuzingelwa kwesibali.

Kungani isibali siyinombolo engathakazelisi kakhulu

Amanani alungisiwe akuzona izingxenye ezingashintshwa. Amanye izikhawu zokuzama futhi, amanye imikhawulo ephezulu yomzamo, futhi amanye asebenza kanyekanye namanye. Ukuwahlanganisa kukhiqiza inombolo ebukeka njengesibikezelo futhi eziphatha njengehemuhemu. Funda imibhalo yensimu ozoqala ukuyithinta, futhi qaphela ukuthi iyiphi kwezinhlobo ezintathu.

Ezinye izigaba akuzona nhlobo izibali. Ukulibazisa kokuxhuma kabusha, isicelo sokuqinisekisa esisebenzisanayo noma iklayenti elihlola kabusha ukulungiselelwa kwalo kuphela lapho liqala kabusha kungase kubuse ukunqamuka kuyilapho isibali ngasinye seprotocol sihlezi phansi ngokunethezeka.

Linganisa isigaba esiphuzi ngempela

Bamba ukwehluleka kanye, ngamamaki esikhathi kuzinhlangothi zombili, bese uqhathanisa izehlakalo ezine esikhundleni sezibalo ze-protocol ngokwayo. Iwindi lokubuka elenziwe kahle lingcono kunezinyanga zokulungisa.

Uma indawo yokugcina enye ingaphenduli neze, akukho shintsho lwesibali olusiza, ngoba ukungafinyeleleki akusiyo inkinga yokutholwa. Uma isimo esisha sokuphepha sakheka ngokushesha kodwa umgwaqo usakhomba endleleni efile, inkinga isekufakweni komgwaqo futhi okunye ukulungisa kokuphila kwengeza isiphithiphithi kuphela.

Enye indlela kufanele ibe isivele isebenza

Ikhophi yokugcina echazwe ekulungiselelweni ayiyona ikhophi yokugcina esebenzayo. Kufanele ifinyeleleke kusukela kunethiwekhi yamanje yeklayenti, ikwazi ukuqinisekisa ubunikazi obufanayo, futhi ivunyelwe ukuthwala ithrafikhi efanayo ngaphansi kwenqubomgomo efanayo. Uma uthola enye yalezi zikhala ezintathu ngesikhathi sokuphazamiseka, ingxoxo yesibali iyaphelela. Hlola enye indlela ngenkathi eyesibili inempilo, ngoba yilapho kuphela ongafunda khona womabili amalogi ndawonye.

Lungiselela enye indlela kusengaphambili, yihlole ngamabomu ngenkathi eyesibili inempilo, futhi ubhale ukuthi yisiphi sezigaba ezine esithatha isikhathi. Lowo mbhalo yiwona owenza ushintsho olulandelayo lube isilinganiso esikhundleni sokuqagela.

Isiphithiphithi sokubuyela emuva nomgwaqo wokuphatha

Ukubuyisela eyesibili isinqumo esihlukile. Ukubuyela emuva ngamandla kungaphazamisa umsebenzi owawusuvele walulama kukhophi yokugcina, futhi umgwaqo odlidlizayo ungabonakala njengomgudu ongazinzi lapho iphutha langempela liwumgwaqo oqhubeka udlidliza phakathi kwezinketho ezimbili ezilinganayo.

Imigwaqo emibili yezindleko ezilinganayo ngaphandle kokuncamelayo iwumthombo ojwayelekile wokudlidliza okubonakalayo, ngoba umqaphi ngamunye usabela ekukhetheni komunye. Nquma ukuthi uwuphi umgwaqo othandwayo ngaphansi kwezimo ezijwayelekile, futhi wenze lokho kuncamela kucace ekulungiselelweni esikhundleni sokukushiya ekuhlelweni kwemigwaqo. Chaza kusengaphambili ukuziphatha kokubuyela emuva okufunayo nokuthi ngubani ongumnikazi wako. Gcina izilungiselelo zangaphambilini kanye nomgwaqo wokuphatha ozimele, ngoba ushintsho olususa ukufinyelela kwakho ngesikhathi sokuphazamiseka lushintsha isigameko senethiwekhi sibe uhambo lwendawo.

Bese uphinda umthwalo ofanayo womsebenzi futhi uqhathanise amamaki afanayo esikhathi amane. Ukubuyisela okufushane okusashiya uhlelo lulindile umgwaqo ofanayo ongekho noma ukungena akusona inqubekela phambili, kuyinombolo ehlukile kugrafu efanayo.
