Imodi ye-SOCKS ye-NetGuard ihlanganisa i-TCP, hhayi wonke umthetho wokuxhumana

I-NetGuard ithatha isixhumanisi se-VPN se-Android ukuze ihlunge ithrafikhi, futhi ingadlulisela izixhumanisi ezisekelwayo endaweni yokugcina ye-SOCKS. Lawa maqiniso amabili avame ukufundwa njengokuthi “ifoni ise-VPN”, okuyisiphetho umshini ongakusekeli. Isihlungi sibona amaphakethe; i-proxy ibona kuphela izixhumanisi ezinikezwe yona ngempela. Phakathi kwalezi zitatimende ezimbili kukhona wonke umbuzo wokuhlinzeka.

Imibuzo evamile yephrojekthi yomthombo ibhala kokubili umkhawulo wesevisi eyodwa kanye nokukhetha kwe-SOCKS. Ukuba khona kokukhetha akubona ubufakazi bokuthi iphakethe ngalinye elivunyelwe liyikusebenzisa, futhi imibuzo yokuhlinzeka ivela kuleli gebe.

Izindlela ezimbili zokudlulisela ngaphakathi kohlelo lokusebenza olulodwa

Uhlangothi lwe-TCP lokuqaliswa luqukethe ukuphathwa kwezixhumanisi ze-SOCKS, ngakho isixhumanisi se-TCP esivunyelwe singaxoxisana ne-proxy futhi sidluliswe kuyo. Uhlangothi lwe-UDP lunendlela ehlukile yesokhethi, futhi ukuphathwa kwayo kokuthumela nokwamukela akuncikile kulokho kuxoxisana kwe-TCP. Ngakho idetagramu evunyelwe isihlungi ingafinyelela inethiwekhi evamile ngaphandle kokudlula ku-proxy. Akukho kulokhu okuyiphutha kohlelo; yilokho nje okwenziwa yizindlela ezimbili.

Lomehluko unomphumela abantu abawuchaza ngokungalungile kuzo zombili izinhlangothi. Ukubiza iphakethe ngalinye le-UDP ngokuthi ukuvuza kushaya indiva imithetho yokuvimbela, ngoba idetagramu enqatshiwe ayiphumi neze. Ukubiza lonke uhlelo ngokuthi i-VPN kushaya indiva indlela eqondile evunyelwe, ngoba ithrafikhi ethile iphuma ngempela ngaphandle kwe-proxy. Lokho onakho idivayisi ehlungiwe ene-proxy engxenyeni, futhi incazelo eqotho iyimatrix, hhayi ilebula.

Ukukhangisa i-UDP akukhona ukuyisebenzisa

Iseva ye-SOCKS ethi isekela i-UDP ayifaki ukuphathwa okuhambisanayo kohlangothi lwekliyenti kuhlelo kufoni yakho. Izici zethiyori zomthetho wokuxhumana nokuziphatha kokwakhiwo okufakiwe kuyizihloko ezihlukile, futhi ukuphela kwesibili okuchaza ithrafikhi yakho.

Hlola inguqulo nokucushwa okukusebenzisayo ngempela, bese uhlola ukugeleza kwedetagramu okungenabungozi futhi ubheke ukuthi kuvela yini ku-proxy. Konke okunye ukucabanga okuvela ohlwini lwezici, futhi izinhlu zezici zichaza izinhloso, hhayi izindlela zekhodi.

I-DNS iyindlela yesithathu, hhayi imininingwane

Ukuxazululwa kwamagama kwengeza igatsha lako kumatrix. Isidluliseli se-DNS sendawo, umbuzo ojwayelekile we-UDP, igama lomsingathi wendawo okuxazululwa yiyo i-proxy kanye nesixazululi esibethelwe kusiphequluli kuyizinhlelo ezine ezihlukile. Ziyahluka ngokuthi ubani obona umbuzo nokuthi iyiphi indlela yenethiwekhi ewuthwalayo, futhi ukuzihlanganisa kukhiqiza ukuhlolwa okungafakazi lutho ngezinye.

Nquma ngokuqwashile ukuthi iyiphi oyifunayo. Uma imfuneko iwukuthi amagama axazululwe ngomhubhe, ukucushwa kwesiphequluli kuphela ngeke kukunikeze lokho, futhi i-proxy exazulula ngokwayo amagama emisingathi ishintsha impendulo kuphela kulezo zixhumanisi eziyiphatha ngempela.

Ukuthutha nge-proxy akukhona okuyimfihlo ngokuzenzakalela

I-SOCKS elula akuyona isixhumanisi esibethelwe esisuka efonini siye ku-proxy. Uma indawo yokugcina ifinyelelwa ngendlela enye evikelwe, shono leyo ndlela nenqubomgomo yayo yokwehluleka, ngoba ukubuyela kunethiwekhi evulekile kwenza uhlelo oluyimfihlo lube olusesidlangalaleni ngaphandle sesexwayiso. Ukufakazela kwe-proxy ngokwayo nakho kubalulekile: isilaleli esivulekile kudivayisi eyabiwe iyisevisi okungekho muntu oyiphendulayo.

Izinhlelo phakathi kwamaphrofayili zifanelwe ukuhlolwa okufanayo. I-VPN yephrofayili yomsebenzi ivikela kuphela ithrafikhi esebenzisa indlela yayo, futhi ukuba khona ndawonye kwe-firewall yephrofayili yomuntu siqu nomhubhe womsebenzi akufakazi ukuthi uxhumano olulandelayo lwe-firewall lufinyelela kulo mhubhe. Qinisekisa ukufinyeleleka nokufakazela esikhundleni sokucabanga ukuthi amaphrofayili amabili ayasebenzisana.

Hlola ukuhlinzeka ngematrix, hhayi ngokulayisha ikhasi

Ukuze kube nokuhlolwa okugunyaziwe, khetha izibonelo ezingenabungozi ezimele isigaba ngasinye osikhathazayo: i-TCP edingekayo, i-UDP evunyelwe kanye ne-DNS kuzo zombili imindeni yamakheli. Kwesinye ngasinye, bhala ukuthi senziwa nge-proxy, savinjwa noma sathunyelwa ngqo. Lelo thebula elilodwa liwumphumela, futhi liwusizo kakhulu kunomfanekiso wesikrini wekhasi elilayishiwe.

Uma imfuneko iwukuthi yonke ithrafikhi yohlelo ekhethiwe kufanele idlule emhubheni okude, khetha ukuqaliswa okusekela ngokusobala ukuhlunga nokuhamba emhubheni okuhlanganisiwe. Ukwakhiwa kwe-proxy ye-TCP kuphela kusasebenza emisebenzini emincane, inqobo nje uma enye ithrafikhi iphathwa ngamabomu hhayi ngokukhohlakala.
