Vanhu pasi rese vanoshandisa maproxi ekutengeserana kuvanza nzvimbo yavo chaiyo kana kuzivikanwa. Izvi zvinogona kuitwa kugadzirisa matambudziko akasiyana, kusanganisira kuwana ruzivo rwakavharika kana kuve nechokwadi chekuvanzika.
Asi vanopa vevamiriri vakadaro vakarurama sei pavanotaura kuti maseva avo ari mune imwe nyika? Uyu mubvunzo wakakosha, mhinduro kune iyo inosarudza kana imwe sevhisi inogona kushandiswa zvachose nevaya vatengi vane hanya nezvekuchengetedzwa kweruzivo rwemunhu.
Boka revasayendisiti veAmerica kubva kumayunivhesiti eMassachusetts, Carnegie Mellon naStony Brook vakaburitswa. , panguva iyo nzvimbo chaiyo yemaseva evanomwe vanozivikanwa vanopa proxy yakatariswa. Takagadzirira pfupiso pfupi yemhedzisiro huru.
Nhanganyaya
Proxy operators kazhinji havapi chero ruzivo runogona kusimbisa chokwadi chezvavanotaura nezvenzvimbo dzeseva. IP-kune-nzvimbo dhatabhesi inowanzo tsigira zvichemo zvekushambadzira zvemakambani akadaro, asi pane humbowo hwakakwana hwekukanganisa mune idzi dhatabhesi.
Munguva yekudzidza, masayendisiti eAmerica akaongorora nzvimbo dze2269 proxy servers dzinoshandiswa nemakambani manomwe eproxy uye dziri munyika dzakawanda nematunhu mazana maviri nemakumi maviri nemaviri. Ongororo iyi yakaratidza kuti chikamu chimwe muzvitatu chese maseva haawanikwe munyika dzinonzi nemakambani mune yavo yekushambadzira zvinhu. Pane kudaro, ivo vari munyika dzine yakachipa uye yakavimbika yekutambira: Czech Republic, Germany, Netherlands, UK uye USA.
Server Nzvimbo Analysis
Commerce VPN nevanopa proxy vanogona kukanganisa kurongeka kweIP-kune-nzvimbo dhatabhesi - makambani ane kugona kushandura, semuenzaniso, macode enzvimbo mumazita e router. Nekuda kweizvozvo, zvigadzirwa zvekushambadzira zvinogona kutora nhamba huru yenzvimbo dzinowanikwa kune vashandisi, nepo muchokwadi, kuchengetedza mari nekuvandudza kuvimbika, maseva ari munyama ari munhamba shoma yenyika, kunyangwe IP-kune-nzvimbo dhatabhesi inotaura zvinopesana.
Kuti utarise nzvimbo chaiyo yemaseva, vaongorori vakashandisa inoshanda geolocation algorithm. Yakashandiswa kuongorora kutenderera kwepaketi yakatumirwa kune sevha uye mamwe mahosi anozivikanwa paInternet.
Panguva imwecheteyo, isingasviki 10% yevamiriri vakaedzwa vanopindura ping, uye nezvikonzero zviri pachena, masayendisiti haana kukwanisa kumhanyisa chero software yezviyero pane server pachayo. Vaingokwanisa kutumira mapaketi kuburikidza neproxy, saka rwendo rwekudzoka kune chero nzvimbo munzvimbo inguva iyo inotora packet kufamba kubva kune bvunzo host kuenda kune proxy uye kubva kune proxy kuenda kwainoenda.
Munguva yekutsvagisa, software yakasarudzika yakagadziridzwa zvichibva pane ina inoshanda geolocation algorithms: CBG, Octant, Spotter uye hybrid Octant/Spotter. Solution kodhi paGitHub.
Sezvo zvaive zvisingagoneke kuvimba neiyo IP-kune-nzvimbo dhatabhesi, kune zviedzo vaongorori vakashandisa iyo RIPE Atlas runyoro rweanchor hosts - ruzivo rwuri mudhatabhesi iri rinowanikwa online, rinogara richivandudzwa, uye nzvimbo dzakanyorwa dzakarurama, uyezve. , mauto kubva pane rondedzero anogara achitumira zvikwangwani zveping kune mumwe nemumwe uye kugadzirisa data parwendo rwekutenderera mudura reruzhinji.
Yakagadziridzwa nemasayendisiti ekugadzirisa, ibasa rewebhu rinogadza yakachengeteka (HTTPS) TCP yakabatana pamusoro peiyo isina kuchengetedzwa HTTP port 80. Kana sevha isingateereri pachiteshi ichi, zvino ichakundikana mushure mekukumbira kumwe, zvisinei, kana sevha iri kuteerera. pachiteshi ichi, ipapo bhurawuza rinogashira SYN- ACK mhinduro neTLS ClientHello packet. Izvi zvinokonzeresa kukanganisa kweprotocol uye bhurawuza richaratidza kukanganisa, asi mushure mekudzoka kwechipiri.
Nenzira iyi, webhu application inogona nguva imwe kana maviri kutenderera. Sevhisi yakafanana yakaitwa sechirongwa chakatangwa kubva pamutsetse wekuraira.
Hapana wevanopa vakaedzwa anozivisa nzvimbo chaiyo yemaseva avo eproxy. Kunyanya, maguta anotaurwa, asi kazhinji kune ruzivo rwenyika chete. Kunyangwe kana guta richitaurwa, zviitiko zvinogona kuitika - semuenzaniso, vaongorori vakaongorora faira yekumisikidza yeimwe yemaseva inonzi usa.new-york-city.cfg, yaive nemirayiridzo yekubatanidza kune server inonzi chicago.vpn-provider. muenzaniso. Saka, zvakanyanya kana zvishoma, unogona kungosimbisa kuti sevha ndeyeimwe nyika.
Mhinduro
Zvichienderana nemhedzisiro yebvunzo vachishandisa inoshanda geolocation algorithm, vaongorori vakakwanisa kusimbisa nzvimbo ye989 kunze kwe2269 IP kero. Panyaya ye642, izvi hazvigone kuitwa, uye mazana matanhatu nemakumi matatu nenhatu havasi munyika mavanofanira kunge vari, maererano nekuvimbiswa kwevashandi veproxy. Anopfuura mazana mana emakero enhema aya ari mukondinendi imwe chete nenyika yakaziviswa.
Kero dzakakodzera dziri munyika dzinowanzo shandiswa kugamuchira maseva (tinya pamufananidzo kuti uvhure muhukuru hwakazara)
Vanofungira mauto vakawanikwa pane mumwe nemumwe wevanomwe vanopa vakaedzwa. Vatsvagiri vakatsvaga mhinduro kubva kumakambani, asi vese vakaramba kutaura.
