Isekhethi elisha le-Tor uma kuqhathaniswa nokushintsha iseva ye-VPN: yini eshintshayo ngempela
Ukushintsha isekhethi kuhambisa indlela ye-Tor, ukushintsha iseva kuhambisa umkhawulo wethaneli. Ukuthi iyiphi eshintsha ikheli elibonwa isayithi kuncike ekulandeleni.
Ukushintsha isekhethi se-Tor nokushintsha iseva ye-VPN kokubili kuzwakala njengokuthola umzila omusha, kodwa kuyaphuka ezindaweni ezahlukene uma uzithatha njengenkinobho eyodwa. Okukodwa kucela iklayenti le-Tor ukuthi lakhe indlela ehlukile yesayithi, okunye kucela iklayenti le-VPN ukuthi lixhumeke kumkhawulo ohlukile. Akukho kokubili okuwukusetha kabusha, futhi ikheli isayithi elibona ekugcineni lincike ekutheni iyiphi kulezi zimbili eseduze nomgomo. Nazi indlela enginquma ngayo ukuthi yisiphi isilawuli engisisebenzisayo, nokuthi ngibheka ini ngemva kwalokho.
Imisebenzi emibili ezingqimbeni ezimbili ezahlukene
I-Tor iyingqimba ephezulu. Iklayenti lakho likhetha i-relay yokuqapha, i-relay ephakathi ne-relay yokuphuma, bese lithwala imifudlana ye-TCP ngaleyo sekhethi; umgomo ubona ukuphuma futhi akukho okunye. Ukushintsha isekhethi yisinqumo esithathwa ngaphakathi kwe-Tor mayelana nokuthi iyiphi i-relay ethwala umfudlana.
I-VPN iwumhubhe ongaphansi. Iklayenti likhetha umkhawulo, lisonge ithrafikhi engqimbeni yangaphandle, futhi konke okulandela kubona ikheli lomkhawulo. Ukushintsha iseva yisinqumo mayelana nokuthi umzila wangaphandle uphela kuphi.
Njengoba izingqimba zizimele, umsebenzi owodwa ungabonakali kolunye uhlangothi lokuxhumana. Lokho kungalingani kuchaza ingxenye enkulu yokudideka mayelana nalezi zilawuli ezimbili.
I-New Tor Circuit for this Site yenzani
I-New Tor Circuit for this Site kuphaneli yolwazi lwesayithi ivala imifudlana i-Tor eyithwalayo yaleyo sayithi bese yakha isekhethi entsha yesicelo esilandelayo. Amathabu, amakhukhi, ukungena kanye nayo yonke ingxenye yokuhlala kuhlala khona kanye lapho bekukhona, futhi lokho kuyiphuzu: ugcina ukuhlala ushintshe indlela.
Lokho kuyenza ibe yithuluzi elifanele ihlule elincane: i-relay yokuphuma umgomo oyivimbayo, umjikelezo we-captcha olandela ukuphuma, noma isayithi elilodwa elimayo ngenkathi zonke ezinye zisihle. Umbukiso wesekhethi kulelo phaneli ubalula ama-relay amathathu, ngakho ungaqinisekisa ukuthi ukuphuma kwashintsha ngempela esikhundleni sokucabanga.
Qaphela umqaphi. I-Tor igcina isethi encane yabaqaphi bokungena, futhi ukushintsha isekhethi ngokuvamile kusebenzisa umqaphi ofanayo, ngakho ukugxuma kokuqala kunethiwekhi akunyakazi. I-New Identity ukusetha kabusha okukhulu: ivala amathabu futhi isule isimo sokuphequlula ngaphambi kokwakha isekhethi entsha, futhi izilawuli zobuwena zibhalwe ngokwehlukile ngesizathu: umsebenzi ohlukile onezindleko ezihlukile.
Ukushintsha iseva ye-VPN kenzani
Iklayenti lidiliza umhubhe bese lixhumeka komunye umkhawulo. Ukugxuma okulandelayo ngaphandle komhubhe, kungaba umqaphi we-Tor noma umgomo ngokwawo, kubona ikheli lomthombo elihlukile. Ukuxhumana ngaphakathi komhubhe kuyaphuka futhi kufanele kusungulwe kabusha, ngakho amakhasi angalenga kuze kuphele isikhathi sawo esikhundleni sokulayishwa kabusha ngokuhlanzekile.
Akukho okuphezu komhubhe okubhalwa kabusha, kodwa ukudilizwa akubonakali. Ekuhlelweni lapho i-VPN iphambi, ukuphuma kusakhethwa yi-Tor, kodwa ukulahla umhubhe kubulala ukuxhumana kwe-TCP i-Tor eyibambe kumqaphi wayo, ngakho i-Tor idiliza leyo sekhethi futhi yakhe emisha, iphinde ikhethe ukuphuma. Ngakho isayithi singabona ikheli lokuphuma elihlukile ngemva kokushintsha, nakuba ukushintsha uqobo kungazange kukhethe elilodwa. Okunqunywa ukushintsha ikheli umqaphi akubonayo; isekhethi eyakhiwe kabusha yisona esiphinde sikhethe ukuphuma. Uma ushintshe amaseva kuphela ukuze ushintshe lokho isayithi esikubonayo ngenkathi i-Tor iphambi, uhambise ingqimba isayithi engakaze isibone ngqo, futhi noma yiluphi ushintsho isayithi esilubonile lwavela ekwakheni kabusha, hhayi ekushintsheni.
Ukushintsha kuthinta kuphela umzila iklayenti elinawo. Isiphequluli esisebenzisa kabusha ukuxhumana okuvuliwe singabonakala sinamathele emzileni wakudala kuze kuxhumeke kabusha, futhi impendulo ye-DNS egciniwe ingenye into evamile evimbayo. Layisha kabusha kuqala, bese uhlulela.
Ukulandelana kunquma lokho umgomo akubonayo
Ukulandelana okubili kuphendula imibuzo ehlukene. Lapho i-VPN iphambi kwe-Tor, umqaphi nama-relay abona umkhawulo we-VPN ngenkathi umgomo ubona ukuphuma kwe-Tor. Lapho i-Tor iphambi kwe-VPN, umgomo ubona umkhawulo we-VPN, ngoba umhubhe yinto yokugcina ithrafikhi edlula kuyo.
| Setup | Switch VPN server | Change Tor circuit |
|---|---|---|
| VPN, then Tor | Guard sees the new address; the rebuilt circuit re-chooses the exit, so the site may see a different exit, not necessarily the same one. | Site sees a new exit; the VPN endpoint is untouched. |
| Tor, then VPN | Site sees the new VPN address immediately. | Circuit is rebuilt, but the site still sees the VPN address. |
Ngakho ukubheka i-IP kubika lokho umgomo akubonile, hhayi umzila okuyithwalile. Isevisi ekhombisa ukuphuma kokunye ukuhlela ne-VPN kokunye iyaziphatha kahle, ayivuzeni idatha.
Lokho akukho kokubili okukwenzayo
Akukho kokubili okususa ubuwena be-akhawunti. Ingxenye yokuhlala ongene kuyo iyikhukhi kanye nerekhodi ohlangothini lweseva, futhi ukushintsha umzila akuthinti kukho kokubili. Iphrofayela yesiphequluli ezinzile, ukungena okufanayo kanye nomprenti womunwe ofanayo zisinda kuzo zombili izenzo.
Akukho kokubili okuwubufakazi futhi. Isayithi sibika ikheli esilubonile ngesikhathi sesicelo; asikwazi ukubika umzila wakho wama-relay noma ukuthi i-VPN yakho yawa imizuzu eyishumi ngaphambilini. Uma uwudinga lowo mhlahlandlela wesikhathi, wubhale ngaleso sikhathi, ngoba awukwazi ukwakhiwa kabusha kusukela kolunye uhlangothi ngemva kwalokho.
Hlanganisa isilawuli nomkhondo
Qala ngokwehlulekile, hhayi ngenkinobho ebukeka ijulile:
- Isayithi elilodwa likuvimbela, ama-captcha ayajikeleza, noma isayithi elilodwa lincane: isekhethi entsha yaleyo sayithi.
- Ukuhlelwa kwe-VPN kuphela kudinga ikheli elibonakalayo elihlukile: shintsha iseva.
- Ubulindele ukuphuma kodwa isayithi sibika i-VPN yakho: hlola ukulandelana, i-Tor ingemva komhubhe.
- Amathabu avaliwe futhi konke kusethwe kabusha: usebenzise i-New Identity, hhayi ukushintsha isekhethi.
- Ukuphuma kubonakala kungashintshile ngemva kokushintsha isekhethi: ama-relay angaphinda ngokusemthethweni, futhi umqaphi awunyakazi nhlobo.
Bhala isenzo nomkhondo okwakufanele kuwulungise ngaphambi kokushintsha enye into. Ukushintsha kabili kulandelana kukhiqiza ukuqhathanisa okungeke kuhunyushwe, futhi ukuphinda kokubili lapho kungqimba eyodwa kuphela engaziphathi kahle yindlela ukuhlola kwemizuzu emihlanu okuba yintambama yonke.
