I-VPN yabalingani isenezincikazo ezimaphakathi
Indlela eqondile yedatha phakathi kwabalingani isengadinga ukubhaliswa, ukutholakala kanye ne-relay. Qhathanisa le misebenzi emithathu ngokwehlukana ngaphambi kokubiza i-VPN ngokuthi ayinamaphakathi.
I-peer-to-peer ichaza ukuthi amaphakethe ezinhlelo ahamba kanjani, futhi akukho okunye. Abalingani kwakusadingeka ukuthi batholane, bafakaze ukuthi bangobani futhi ngezinye izikhathi baphendukele ku-relay lapho indlela eqondile yayingakhiwa. Lezi yizinsizakalo ezintathu ezihlukene, futhi ukusetshenziswa kungaba yi-peer-to-peer yedatha kuyilapho kugxile ngokuphelele kukho konke okunye. Ukuqhathanisa amadizayini kusho ukuqhathanisa leyo misebenzi, hhayi umcibisholo osesithombeni.
Isithombe esingenaye umcibisholo wokudlulisa omaphakathi singafihla isiphathimandla sokubhalisa, insizakalo yokutholakala kanye ne-relay, konke lokhu kuyizincikazo zokusebenza.
Indlela eqondile, indawo yokulawula ehlanganyelwe
Imishini emibili eshintshana ngamaphakethe ngqo isenganokuncika kwisiphathimandla esihlanganyelwe esakhipha izitifiketi zayo kanye nensizakalo eyatshela ngayinye ukuthi enye ikuphi. Azikho izindima zombili ezidlulisa ithrafikhi yezinhlelo, yingakho umdwebo wethopology uzishiya. Lapho leso siphathimandla noma lena nsizakalo ingekho, amaseshini akhona angaqhubeka kuyilapho iqembu elisha lingenakujoyina. Umehluko phakathi kokuqala iseshini nokuqhubeka nayo umbuzo wokuqala okufanele ubuzwe kunoma yimuphi umklamo.
Dweba umsebenzi ngamunye ngokwehlukana ngisho lapho isibungu esisodwa senza konke. Uma kungenjalo umdwebo ukhombisa indawo yedatha engaxhomekekile futhi ufihla iqiniso lokusebenza lokuthi iqembu elisha ngalinye lidinga lezi zinsizakalo ezimbili.
Ukutholakala, ukuthembana ne-relay imisebenzi emithathu
Umklamo we-Nebula uyisibonelo esiwusizo ngoba imibhalo yaso uyahlukanisa. Amahosthi athwala izitifiketi zobunikazi, o-thisha baphendula umbuzo wokuthi kuphi futhi basiza ekweqeni i-NAT, futhi ama-relay adlulisa ithrafikhi lapho indlela eqondile ingakhiwa. Indima ye-relay ihluke ngamabomu endimeni yothisha, ngakho uthisha ofinyelelekayo akaqinisekisi ukuthi ipheya elithile lingakhuluma. Eminye imikhiqizo idweba imingcele kwenye indawo, yingakho lokhu kuyisibonelo hhayi ithempulethi.
Okokuthunyelwa okuhlongozwayo, bhala indlela yokubuyisela esekelwayo yepheya elingakwazi ukuxhuma ngqo. Ukubhoboza imbobo okwehlulekile kuyiphuzu ledatha elilodwa mayelana nenethiwekhi eyodwa, hhayi ubufakazi bokuthi amaqembu amabili angemuva kwe-NAT awasoze ahlangana; isimangalo esiphambene, sokuthi ukuxhumana okuqondile kuyasebenza ngaphansi kwanoma yimuphi umgomo, naso asinasisekelo.
Yini okwehluleka kuyo ukuncika ngakunye
Hlola izimo ezine ngokwehlukana ngesikhathi ukuncika okuhlolwayo kungatholakali: ithrafikhi ekhona phakathi kwamaqembu, ukuxhumana kweqembu elisha ngokuphelele, iqembu elishintshile indawo yokugcina, nokufinyelela okusanda kuhoxiswa. Ngamunye uncika ezinsizakalweni ezahlukene futhi wehluleka ngendlela ehlukile. Amaseshini akhona angasinda ekuphazamisekeni kokutholakala kuyilapho ukhiye ohoxisiwe usanqatshwa, futhi iqembu elisha lingehluleka ngezizathu ezingahlobene nokudlulisa. Zihlole ngazinye esikhundleni sokuphetha kwelilodwa.
Ukuxhumana okusinda ekuphazamisekeni okukodwa akubonisi ukuzimela okungenamingcele. Kubonisa ukuthi ukuphazamiseka okukubangele kwakungekhona okuqeda leyo ndlela, okuyisaziso esiwusizo uma ubhale phansi ukuthi wabangela ini.
Buza ukuthi yikuphi ukuphazamiseka ongakusinda
Izidingo ezizwakala zifana ziholela emiklamoni ehlukene. Ukugwema umgwaqo oyisicindezeli wokudlulisa akufani nokugwema indawo yokulawula ephethwe umphakeli, futhi akukho kokubili okuhambisana nokuqhubeka nokusebenza ngesikhathi umxhumanisi engekho. Shono ukuthi yikuphi kwezintathu okufanele kuhlangatshezwe ukuthunyelwa, bese uhlola ukuhlangana. Umklamo ohlangabezana nokokuqala futhi wehluleka kwesibili uvamile futhi awukona ukungathembeki, inqobo nje uma kungekho oyibiza ngokuthi ayinamaphakathi ngokuphelele.
Bhala ukuthi ngubani ophethe ukutholakala, ukuthembana nama-relay, nokuthi ngakunye kushintshwa kanjani. Lelo rekhodi yilo elivumela umuntu olandelayo ukuthi aphendule umbuzo wangempela: yikuphi ukuhluleka okusindayo le nethiwekhi, futhi ngubani ogcina isimo esisahlanganyelwe?
Igama elithi ayinamaphakathi lithola indawo yalo lapho libala leyo kuhluleka. Ngaphandle kwalelo hlu, lichaza umdwebo hhayi uhlelo.
