Isithonjana esixhunyiwe singase sisho umhubhe wohlelo lokusebenza olulodwa noma ukuhlolwa okukodwa okuphumelele. Chaza ububanzi, thatha ukufundwa kwakudala njengokungaziwa, futhi wehlukanise ukuvinjwa.
Isithonjana se-VPN esiluhlaza siyisimangalo mayelana nokuthile, futhi umbuzo owusizo ukuthi mayelana nani. Ocingweni kungase kubonise umhubhe weklayenti elilodwa, ukuthuthwa kwenethiwekhi yamanje, noma isicelo esisodwa esiphumelele kukhasiwangaphakathi. Lokhu kubheka kuvela emithonjeni ehlukene, kuyavuselelwa ngezinga elihlukile, futhi kungase kungavumelani esikrinini esisodwa. Yingakho isithonjana singabonakala siphilile kuyilapho isiphequluli esiphambi kwakho sihluleka.
Chaza ububanzi ngaphambi kokufunda umbala, uma kungenjalo umbala uzophendula umbuzo ongazange ubuzwe muntu.
Isithonjana siphendula umbuzo omncane kunalokho ocabangayo
Qala ngobubanzi obulodwa obumenyezelwe, njengesiphequluli somuntu siqu esisebenzisa umhubhe womuntu siqu ogunyaziwe. Umhubhe wephrofayela yomsebenzi awuphenduli lowo mbuzo wohlelo lokusebenza lomuntu siqu, futhi ukulungiselelwa kwe-VPN ngohlelo ngalunye kungase kukhiphe isiphequluli osihlolayo. Iklayenti lokuhlunga lendawo kungase libonise kuxhunyiwe kuyilapho lingathumeli lutho kusango elikude, ngoba umhubhe walo uphela kudivayisi.
Ku-Android, izingcingo zenethiwekhi ezingemuva kwesikhombisi zibika ukuthuthwa namakhono enethiwekhi. Ukuthuthwa kwe-VPN kusho ukuthi iyiphi inethiwekhi ethwala ithrafikhi, hhayi ukuthi yiziphi izinhlelo noma imindeni yamakheli ezisebenzisa yona.
Akha ithebula lezimo ngobufakazi
Izimo ezintathu noma ezine zanele uma ngayinye isho ubufakazi obungemuva kwayo. Amakholomu angezansi aqala kulokho okungabonwa hhayi kumbala ofuna ukuwubonisa, futhi lokho kuvimbela ukufundwa kwakudala ukuba kube isimangalo sempumelelo.
| Signal actually observed | What it establishes | What remains open |
|---|---|---|
| Target client reports an established tunnel | That client believes its tunnel is up, within its own scope | Other apps, other profiles, other address families |
| Active network exposes a VPN transport | Some tunnel carries the current network | Which app it belongs to and where it exits |
| Probe to a private host returned fresh data | One request reached one destination at one time | Everything the probe does not touch |
| Callbacks stopped or data is older than the refresh window | Nothing current is known | Any statement about the tunnel state |
Umugqa wokugcina yiwo ovame ukushiywa emsebenzini. Isikhombisi esigcina inani laso lokugcina uma umthombo waso ufa sibika umlando sengathi ungowamanje, futhi abasebenzisi bakufunda njengesimo esiphilayo. Bhala leso simo njengesidala noma esingaziwa, futhi khetha amazwi angasho umhubhe. Bese uvumela ilebula ukuthi lishintshe ngokushesha uma umthombo ume.
Hlola ukuthi idivayisi ibika ini ngempela
Isibani somzimba noma iwijethi kufanele siqhutshwe ukubheka okusekelwe, hhayi ukuqagela mayelana nesimo esihle sokugcina esaziwayo. Lezi ziyalo ze-Android zikhombisa ukuthuthwa nokulungiselelwa koxhumano oluhlala lukhona lwepulatifomu ngaphandle kokufaka lutho.

Izinkinobho zoxhumano oluhlala lukhona zisho ukuthi ipulatifomu ilungiselelwe ukugcina umhubhe nokuvimba ithrafikhi ngaphandle kwawo yini; azisho ukuthi umhubhe unempilo manje. Hlanganisa lokho kufundwa kokulungiselelwa nokuhlolwa okusha ngaphambi kokuba kukhombiswe noma yini njengokuxhunyiwe.
Uma ukubheka kungakwazi ukuqhubeka, isibonisi kufanele sikwazi ukusho lokho. Isibani esixhunywe kumshini osebenza ngokuzenzekela ongasadonsa umsebenzi sibi kunokuba singabikho, ngoba sisho isimo umuntu ongasilingisi.
Wehlukanise isexwayiso nokuphoqelela
Umshini osebenza ngokuzenzekela obona ukunqamuka uvuka ngemuva komcimbi, ngakho awukwazi ukuba umngcele ovimbela iphakethe ukuba liphume phakathi nesikhala. Uma ukubuyela ngqo kufanele kuvinjwe, lungiselela inqubomgomo yokuvimba yepulatifomu futhi uyiqinisekise ngokucima umhubhe ngamabomu. Isikhombisi siyabika; inqubomgomo iyaphoqelela.
Umsebenzi wesexwayiso ocima izixhumanisi ukuze uphoqelele ukuthobela ungase futhi ukhiye idivayisi ngaphandle koxhumano olusha oluyidingayo, lokho kudale umjikelezo lapho umhubhe ungalokothi ubuya futhi isexwayiso singalokothi sikhishwe.
Nquma ukuthi isibonisi kufanele sikhombise ini uma umbukeli engenasiqiniseko, bese uhlola leso simo ngokumisa umbukeli. Uma impendulo iseyikho ukuthi kuxhunyiwe, isikhombisi silinganisa okwedlule.
