proxy ligama elisetyenziswa esiNgesini ukubhekisa kummeli okanye umntu okanye into emele umntu wesithathu. Loo ntsingiselo, idityaniswe ngokufanelekileyo, iye yatshintshelwa kwihlabathi le-Intanethi ukuze kunyulwe eyona nto ibalulekileyo yokwenza uqhagamshelo lwethu. Kule post siza kuchaza yintoni iseva engummeli, yenzelwe ntoni kwaye isebenza njani.
Imo yeGross, sinokuchaza umncedisi wommeli njenge umlamli. Umncedisi owenza ukuba kwenzeke ukuba umxhasi (onokuthi abe nathi kwikhompyutheni yethu) ukudibanisa nabanye abancedisi (amaphepha ewebhu). Ukusuka kwindawo yayo ephambili kwindawo ethile phakathi, umncedisi wommeleli unokwenza imisebenzi eyahlukeneyo, ukusuka ekulawuleni ukufikelela ekulawuleni ukungaziwa konxibelelwano, phakathi kwabanye abaninzi.
Xa sibrawuza i-Intanethi, isikhangeli sethu siqala ngokuqhagamshelwa kwi-proxy, ebuyisela itrafikhi kwiwebhusayithi esifuna ukuyindwendwela. Ummeli emva koko ufumana impendulo kwiwebhusayithi kwaye ayibuyisele kuthi. Oku kwenzeka ngo isantya sokuphuka, kangangokuba asiyiboni inkqubo, sikwazi ukucinga ukuba uxhulumaniso lwewebhu luthe ngqo kwaye lukhawuleza. Kodwa akunjalo: ngaphandle komsebenzi womncedisi weproxy ayinakwenzeka.
Uncedo lomncedisi wommeli
Ngoku ekubeni sisazi ukuba yintoni iseva engummeli, kufuneka sizibuze imibuzo ethile: Loluphi usetyenziso lwayo lokwenyani? Zeziphi iingenelo kunye nemisebenzi esinika yona? Esi sisishwankathelo esincinci sezona zibalulekileyo:
i-cache yokugcina
Ezinye iiseva zommeli (ezibizwa ngokuba zii-caching proxies) zinamandla okugcina indawo yokugcina, eluncedo kakhulu fikelela kwiwebhusayithi okanye kwinkonzo ye-intanethi ngesantya esiphezulu. Oku kungenxa yokuba, endaweni yokuthumela isicelo kunye nokulinda impendulo, ukuba i-proxy igcine umxholo kutyelelo lwangaphambili, uxhulumaniso luya kwenziwa ngokukhawuleza.
isiqulatho sesihluzi
Olunye usebenziso olusebenzayo lweeseva zommeli kukucoca umxholo xa usefa umnatha. Kuxhomekeke ekubeni zithini iisetingi zakho, unokude uthintele ukufikelela kwiphepha elithile lewebhu. Lo msebenzi ubalulekile ukuba sicinga malunga ne khu seleko, ukuvala ukufikelela okunokuba yingozi ngenxa yezizathu ezahlukeneyo: i-cyberattacks, i-malware, njl.
Ukukhangela ngasese
Kunye nokhuseleko, kukho umba we ngasese. Umncedisi wommeleli unokusinceda nathi ukufihla idilesi yethu ye-IP yangempela kwaye sifihle indawo yethu, umzekelo. Oko kukuthi, ukukwazi ukukhangela ngokungaziwa.
Iintlobo zeseva yommeli
Kukho iintlobo ngeentlobo zeeseva ezibambayo, ezi zezona zixhaphakileyo:
- Ummeli wewebhu, eyona ixhaphakileyo kwaye isetyenziswa kakhulu. Isekelwe kwi-HTTP kunye ne-HTTPS, esebenza njengomlamli wokufikelela kwezinye iinkonzo kwi-Intanethi. Ummeli wewebhu wesikhangeli sethu uya kutshanela lonke uqhagamshelo lwethu lwe-Intanethi.
- i-caching proxy, iseva ephakathi phakathi kwenethiwekhi esiqhagamshela kuyo kunye ne-Intanethi. Ukusebenziseka kwayo kwaziwa kakuhle: xa si tyelela iwebhusayithi, yonke idatha igcinwa, ngoko akudingekile ukuyiphonononga ngotyelelo lwesibini, ukukhawuleza ukufikelela kuyo.
- umva ummeli. Lo ngumncedisi owamkela zonke iitrafikhi kwaye emva koko uyithumele kwisixhobo esithile. Ngummeli oxatyiswe kakhulu ukufikelela kwinqanaba eliphezulu lokhuseleko kwiqela lethu.
- Ummeli weNAT, olona phawu luphambili kukufihla ubuni babasebenzisi, ukufihla idilesi ye-IP ngolungelelwaniso olwahlukeneyo.
Useta njani iproxy kwiWindows 10
Ukuseta i-proxy kuhlala kungumbono olungileyo ukuba lonke ukhangelo lwethu lwewebhu lulawulwe ngumthetheli, kunye nazo zonke iingenelo ezibandakanya oku kwaye sixoxe ngazo kwimihlathi edlulileyo. Kuqwalaselo lwayo Windows 10, kufuneka ulandele la manyathelo alandelayo:
- Okokuqala, makhe "Ukuqala".
- Ukusuka apho siya "Ukuseta".
- Sikhetha ithebhu "Inethiwekhi kunye neIntanethi".
- Apho sicofa kukhetho "Ummeli".
- Kweli phepha kufuneka wenze ukhetho "Sebenzisa iseva yommeleli", kuba oku kuvaliwe ngokungagqibekanga.
- Ekugqibeleni, songeza idilesi ye-IP kunye nezibuko yaloo proxy.
- Cofa ku "Gcina".
Ummeleli vs VPN: Yintoni umahluko?
Okokugqibela, makhe sicacise intandabuzo eqhelekileyo. Ukufunda ngononophelo imisebenzi yeeseva zommeli, kunokuvela ukubhideka okuncinci: akunjalo na ukuba a VPN? Kuyinyani ukuba bobabini banokwenza izenzo ezifanayo, njengokufihla i-IP, kodwa zizinto ezimbini ezihluke ngokupheleleyo.
Ukuqala, i-VPN ifihla lonke uqhagamshelo lwekhompyuter yethu, ngelixa umncedisi wommeli uya kusebenza kuphela kwitrafikhi yewebhu. Kule nto kulandela ukuba iqondo lokukhusela kunye nokhuseleko olunikezelwa yi-VPN luphezulu kakhulu.
Kwelinye icala, isantya sonxibelelwano iphezulu xa usebenzisa i-VPN. Oku kuphawuleka kancinci xa kufikwa ekusefeni nje umnatha, kodwa kuxa ulayisha okanye ukhuphela iifayile.
Kodwa apho kukho umahluko omkhulu phakathi kweVPNs kunye neeseva zommeli ungaphakathi icandelo lokhuseleko. Kwaye apha kwakhona, i-VPN inika iziqinisekiso ezininzi ngakumbi, nangona sele isaziwa ukuba ukhuseleko olupheleleyo kwi-Intanethi liphupha lombhobho.
