Ingabe i-CPU ye-router noma ye-laptop iphelile? Kungani isivinini sakho se-VPN sima ngaphambi kwesikhathi

I-router ikhanga i-Wi-Fi esheshayo bese izabalaza ukubethela ithrafikhi yamadivaysi amathathu ngesikhathi esisodwa. I-laptop ifinyelela umkhawulo wokucubungula ngenkathi uxhumano lokungena lusenendawo. Ngokuvamile i-server isolwa kuqala, futhi ngokuvamile ayinacala. Umkhawulo usemshinini eyenza umsebenzi we-tunnel, futhi ukuwuthola kusho ukubuka leyo mshini esikhundleni sokuhlolwa kwesivinini.

Isibonakaliso sikhomba kumshini owodwa, hhayi ku-inthanethi

Ukuthi i-tunnel isebenza kuphi kunquma ukuthi iyiphi iprosesa ekhokha ngayo. Uma i-router iyiqeda, iklayenti ngayinye emboziwe yabelana ngesabelomali sale router. Uma i-laptop isebenzisa iklayenti, i-laptop iyakhokha hhayi i-router. Ama-tunnel emikhawulweni yomibili adala imithwalo emibili yomsebenzi futhi ngayinye ingaba umkhawulo ngolunye usuku. Ukuqamba umshini igama yisinyathelo sokuqala, futhi yiso leso sinyathelo abantu abasishiyayo lapho bevula ithikithi ngokumelene nomhlinzeki.

Bala amadivaysi phakathi kohlelo lokusebenza nomkhawulo okude, bese umaka lowo obethelayo. Konke okunye kumane kuyisithwali samabhayithi engakwazi ukuwafunda.

Bheka umthwalo we-core ngayinye phakathi nokudluliswa

Iphesenti le-CPU lilonke iyithuluzi elingalungile, ngoba umsebenzi wokubethela uvame ukubopha i-core eyodwa ngenkathi ezinye zingenzi lutho. Bheka izibalo ze-core ngayinye phakathi nokudluliswa okulawulwayo futhi uqaphele i-core eyodwa eseduze nokugcwala. Isilinganiso esilinganiselayo esinomsonto owodwa omatasa isibonakaliso esinamandla, kuyilapho isilinganiso esiphezulu ngaphandle komsonto omatasa ngokuvamile sisho uhlelo olungahlobene. Iphethini ibaluleke ukudlula inombolo.

Umyalo wesithathu utshela ukuthi iprosesa ihlinzeka ngemiyalo ye-AES yini, lokhu okushintsha izindleko ze-cipher efanayo kakhulu. Awutsheli ukuthi ukusetshenziswa kwe-VPN kuyisebenzisa yini, futhi igebe phakathi kwala maqiniso amabili yilona umsuka wezitatimende eziningi zokuthuthukisa.

Hlukanisa ukubethela nokuphathwa kwamaphakethe

Ukubethela kuyizindleko ezinye kokunye. Ukukopisha amaphakethe phakathi kwe-kernel nesikhala somsebenzisi, ukusesha komzila, imithetho ye-firewall nokuphathwa kwama-interface konke kuyafaka isandla, futhi ezinye izinto zokwenza zikhokha kakhulu ngokukopisha kunange-cryptography. Qaphela ukuthi iyiphi i-counter ekhuphukayo kanye nokudluliswa esikhundleni sokuthembela egameni lenqubo ukuchaza wonke umjikelezo. I-tunnel esikhaleni somsebenzisi kanye ne-tunnel ngaphakathi kwe-kernel kungakhombisa amaphrofayili ahluke ngokuphelele ngenxa yethrafikhi efanayo.

Uma i-core eyodwa imatasa ngaphakathi kwe-kernel, ikhambi lihluka kumsonto omatasa esikhaleni somsebenzisi, futhi iphrofayili ikutshela ukuthi yikuphi okunawe. Lowo mehluko ufanele ihora ngaphambi kokuthenga i-hardware.

Qhathanisa okufanayo nokufanayo ngaphambi kokuphetha

Ukuqhathanisa kusiza kuphela uma umsebenzi, inethiwekhi yokungena nendlela yokugcina kuhlala kufana. Shintsha i-server futhi umphumela uhlanganisa umzila nomthamo wale server; shintsha inethiwekhi futhi uhlanganisa opharetha. Sebenzisa ifayela elifanayo, indawo yokuyofika efanayo nesikhathi sosuku esifanayo, futhi umise umsebenzi wakho wangemuva. Uma kufanele ushintshe idivaysi, shintsha idivaysi kuphela.

Amandla nokushisa kushintsha ukusebenza okuhlala njalo, ngakho ukugijima okufushane kumshini obandayo akusona isilinganiso esifanayo nokudluliswa okude kumshini oshisayo. Qhathanisa izimo zamandla ezifanayo futhi uzibhale phansi, ngoba umkhawulo wokushisa ubukeka ufana ncamashi nomkhawulo wokucubungula kugrafu.

Sebenzisa i-offload esekelwayo futhi uqinisekise ukuthi isivuliwe ngempela

Ezinye izinto zokwenza zingahambisa ingxenye yomzila wedatha kwi-kernel noma kwi-hardware, futhi ukutholakala kuncike kuklayenti, kusistimu yokusebenza, ku-server nakwisimo. Funda imibhalo yenguqulo oyisebenzisayo futhi usebenzise okukhiphayo kwesimo noma amalogi ayo ukuqinisekisa ukuthi isici siyasebenza. Iphakethe elifakiwe noma ibhokisi eliqoshiwe akusona ubufakazi. Incwadi ye-OpenVPN ibhala izinketho zesiteshi sedatha yezinguqulo zayo, futhi lezo zinketho ziyahluka phakathi kwezinguqulo.

Uma ushintsho olusekelwayo luhambisa uphahla, gijima futhi umsebenzi wohlelo lokusebenza nokudluliswa okukhulu, futhi gcina iphrofayili yangaphambilini ukuze ukwazi ukubuyela emuva. Izinga elikhulu eliphindwe kabili ngenkathi uhlelo lusephuzile luhambisile umkhawulo hhayi ukuwususa.

Uma ukubhekwa kweprosesa kungalulandeli isibonakaliso, buyela ohlangothini lwenethiwekhi. Ukuzama kabusha kwe-Wi-Fi, umugqa nendlela yokuphuma kukhiqiza umphumela ofanayo ngaphandle kokuhlanganyela kwe-CPU.
