Ummeleli igama elisetshenziswa esiNgisini ukubhekisela komele noma othile noma into emelela omunye umuntu. Leyo ncazelo, ecatshangelwe kahle, idluliselwe emhlabeni we-inthanethi ukuze kuqokwe into ebalulekile yokwenza ukuxhumana kwethu. Kule post sizochaza yini iseva elibamba, ukuthi ingeyani nokuthi isebenza kanjani.
Imodi yokuthola imali, singachaza iseva elibamba njenge umlamuli. Iseva eyenza kube nokwenzeka ngeklayenti (okungaba yithi ekhompyutheni yethu) ukuthi lixhumane namanye amaseva (amakhasi ewebhu). Kusukela endaweni yayo ebalulekile endaweni ethile phakathi, iseva elibamba ingenza imisebenzi ehlukahlukene, kusukela ekulawuleni ukufinyelela ekulawuleni ukungaziwa kwezokuxhumana, phakathi kwezinye eziningi.
Uma siphequlula i-inthanethi, isiphequluli sethu siqale sixhume kummeleli, oqondisa kabusha ithrafikhi kuwebhusayithi esifuna ukuyivakashela. Ummeleli ube esethola impendulo evela kuwebhusayithi futhi ayibuyisele kithi. Lokhu kwenzeka ngo-a isivinini se-breakneck, kangangokuthi asiyiboni inqubo, sikwazi ukucabanga ukuthi ukuxhumeka kuwebhu kuqondile futhi kuyashesha. Kodwa akunjalo: ngaphandle komsebenzi weseva elibamba bekungeke kwenzeke.
Ukusebenziseka kweseva elibamba
Manje njengoba sesiyazi ukuthi iyini iseva elibamba, kufanele sizibuze imibuzo ethile: Iyini ukusetshenziswa kwayo kwangempela? Yiziphi izinzuzo nemisebenzi esinika yona? Lesi isifinyezo esincane sezinto ezibaluleke kakhulu:
inqolobane yesitolo
Amanye amaseva elibamba (okuthiwa ama-proxy we-caching) anekhono lokugcina isikhashana, eliwusizo kakhulu finyelela iwebhusayithi noma isevisi eku-inthanethi enesivinini esikhulu. Lokhu kungenxa yokuthi, esikhundleni sokuthumela isicelo nokulinda impendulo, uma ummeleli egcine okuqukethwe ekuvakasheni kwangaphambilini, uxhumano luzokwenziwa ngokushesha.
isihlungi sokuqukethwe
Okunye ukusetshenziswa okuphathekayo kwamaseva elibamba ukuhlunga okuqukethwe lapho usefa inethi. Kuya ngokuthi izilungiselelo zakho ziyini, ungakwazi nokuvimba ukufinyelela ekhasini elithile lewebhu. Lo msebenzi ubalulekile uma sicabanga nge ukuphepha online, ukuvimbela ukufinyelela okungaba yingozi ngezizathu ezahlukene: ukuhlasela kwe-inthanethi, uhlelo olungayilungele ikhompuyutha, njll.
Ukuphequlula ngasese
Kanye nezokuphepha, kukhona nodaba lwe ubumfihlo. Iseva elibamba ingasisiza futhi ukuthi sifihle ikheli lethu le-IP langempela futhi sifihle indawo yethu, ngokwesibonelo. Okungukuthi, ukukwazi ukuphequlula ngokungaziwa.
Izinhlobo zeseva elibamba
Kunezinhlobonhlobo eziningi zamaseva ezibamba, lezi yizona ezivame kakhulu:
- Ummeli wewebhu, evame kakhulu futhi esetshenziswa kakhulu. Isekelwe ku-HTTP ne-HTTPS, isebenza njengomxhumanisi ukuze ufinyelele ezinye izinsiza ku-inthanethi. Ummeleli wewebhu wesiphequluli sethu uzosakaza konke ukuxhumana kwethu kwe-inthanethi.
- i-caching proxy, iseva ephakathi phakathi kwenethiwekhi esixhuma kuyo ne-inthanethi. Ukusebenziseka kwayo kwaziwa kahle: lapho sivakashela iwebhusayithi, yonke idatha igcinwa, ukuze kungadingeki ukuyibuyekeza ngokuvakasha kwesibili, ukusheshisa ukufinyelela kuyo.
- i-proxy ehlehlayo. Lena iseva eyamukela yonke ithrafikhi bese iyidlulisela esisetshenziswa esithile. Kungummeleli obaluleke kakhulu ukuzuza izinga eliphezulu lokuphepha leqembu lethu.
- Ummeleli we-NAT, ubuhle bayo obuyinhloko ukufihla ubunikazi babasebenzisi, ukufihla ikheli le-IP ngokulungiselelwa okuhlukahlukene.
Ungayisetha kanjani i-proxy ku-Windows 10
Ukusetha ummeleli kuhlale kuwumqondo omuhle ukuthi konke ukuphequlula kwethu iwebhu kuphathwe umxhumanisi, nazo zonke izinzuzo ezihambisana nalokhu futhi esixoxile ngazo ezigabeni ezedlule. Ngokucushwa kwayo ku-Windows 10, kufanele ulandele lezi zinyathelo ezilandelayo:
- Okokuqala, ake "Kuyaqala".
- Sisuka lapho siya "Ukusetha".
- Sikhetha ithebhu "Inethiwekhi ne-Inthanethi".
- Lapho sichofoza inketho "Ummeleli".
- Kuleli khasi umane kufanele uvule inketho "Sebenzisa iseva elibamba", njengoba lokhu kukhutshaziwe ngokuzenzakalela.
- Ekugcineni, siyengeza ikheli le-IP kanye nembobo yalowo mmeleli.
- Qhafaza "Londoloza".
Ummeleli vs VPN: Uyini umehluko?
Ekugcineni, ake sicacise ukungabaza okuvamile. Ukufunda ngokucophelela imisebenzi yamaseva elibamba, kungavela ukudideka okuncane: akunjalo yini ukuthi a i-VPN? Kuyiqiniso ukuthi bobabili bangenza izenzo ezifanayo, njengokufihla i-IP, kodwa ziyizinto ezimbili ezihluke ngokuphelele.
Okokuqala, i-VPN ibhala ngemfihlo konke ukuxhumana kwekhompuyutha yethu, ngenkathi iseva elibamba izosebenza kuphela kuthrafikhi yewebhu. Kulokhu kulandela ukuthi izinga lokuvikela nokuvikeleka elihlinzekwa yi-VPN liphakeme kakhulu.
Ngakolunye uhlangothi, isivinini sokuxhuma iphezulu uma usebenzisa i-VPN. Lokho akubonakali kangako uma kukhulunywa ngokusefa nje inetha, kodwa kulapho ulayisha noma ulanda amafayela.
Kepha lapho kunomehluko omkhulu phakathi kwama-VPN namaseva wommeleli ungaphakathi ingxenye yezokuphepha. Futhi lapha futhi, i-VPN inikeza iziqinisekiso eziningi ezengeziwe, nakuba sekuvele kwaziwa ukuthi ukuphepha okuphelele ku-intanethi kuyiphupho lepayipi.
