Kungani ukufaka i-opt-verify kungayilungisi iphutha lokubethela le-OpenVPN

Uthola isiphakamiso sokufaka i-opt-verify, ufaka umugqa, futhi iphutha lokubethela lihlala khona lapho lalikhona. Lowo mphumela uyabikezelwa, ngoba inketho ayikaze ixoxisane ngokubethela. Kwakuwukuhlola ukuvumelana kwenketho, okwaphelelwa yisikhathi ku-2.6 futhi kwasuswa ku-2.7, futhi iphrofayela esahlaziywayo nakho ayiphogelelisi lutho ngalokho.

Kuyasiza ukwazi ukuthi umugqa wawusebenza ini ngaphambili ngaphambi kokuphetha ngokuthi uyingxenye engekho. Umlando uphinde uchaze ukuthi kungani awukwazi ukusiza manje.

Okwakuphoqelelwa yinketho ngaphambili

Incwadi yokuqondisa ye-2.6 imaka i-opt-verify njengokuphelelwe yisikhathi futhi ichaza ukuziphatha kwangaphambili: iseva ilahla amaklayenti anenketho ezimisiwe ezingahambisani nezayo, iqhathanisa izinto ezinjengohlobo lwedivayisi ne-MTU. Lokho kuhlola kuncike futhi ekutheni ukuhlola ukuvumelana kwenketho kuqhubeke kuvuliwe, ngakho iseva esisebenza nge-disable-occ ayikaze ibe nakho. Qaphela ukuthi ukuqhathanisa kwakhiwe ngokuthini: umbhalo ochaza ukucushwa kohlangothi olulodwa. Awusho lutho mayelana nokuthi iyiphi indlela yokubethela ezosetshenziswa isiteshi sedatha.

Lesi yisizathu sokuqala sokuthi ifulegi alikwazi ukulungisa iphutha lokubethela. Ukukhethwa kokubethela kubuswa inqubomgomo ye-data-ciphers kanye nalokho okusekelwa yizinhlangothi zombili, futhi ukuhlola ukuvumelana kombhalo akulwandisi lolo hlu futhi akwenzi ukuxoxisana. Isizathu sesibili ububanzi: ukuhlola kumayelana nokuthi inketho ezimisiwe zibonakala zihambisana yini, hhayi ngekhwalithi yomzila ovelayo.

I-2.7 yenza ini uma ibona umugqa

Ku-2.7 inketho ayisekho. Umhlaziyi usayibona igama, yingakho iphrofayela endala ilayishwa ngaphandle kwephutha lomthetho wolimi, futhi ibika ukuthi inketho isusiwe esikhundleni sokuyeqa buthule. Ukubona igama nokuphoqelela ukuziphatha kuyizinto ezihlukene, futhi okwamanje kwenzeka okokuqala kuphela. Amanothi okususa anikeza isizathu: uma amapharamitha esekwazi ukuxoxisanwa, izinhlangothi ezimbili zingaba ngezintambo zenketho ezihlukene ngokusemthethweni ngenkathi zivumelana ngokuxhumana.

Ngakho-ke iphrofayela ehlaziywayo ayibona ubufakazi bokuthi kwenzeke noma yikuphi ukuhlola kokwamukelwa. Uma uphawu lwakho okuwukuphela kwalo kuwukuthi iklayenti ixhumene, ufunde ukuthi umthetho wolimi wamukelwe.

Lapho ukwehluleka kuhlala khona ngempela

Gcina iphutha lokuqala elibonakalayo ngaphambi kokushintsha noma yini, ngoba imiyalezo elandelayo ngokuvamile iyimiphumela yalo. Ukwehluleka kokuxoxisana kwesiteshi sedatha kungaphansi kwenqubomgomo yokubethela egunyaziwe kanye namakhono okukhulunywa ngawo yizinhlangothi zombili. Ukwehluleka kwenguqulo noma kwesethi ye-TLS kungaphansi kwesiteshi sokulawula. Ukunqatshwa kwesitifiketi kudinga ubunikazi kanye nochungechunge lokuthembela, hhayi ifulegi lokuhambisana.

Khomba futhi injini kuzo zombili iziphetho. Uhlelo lwedeskithophu lungafaka ukwakhiwa okuhlukile kunebhinari yomugqa womyalo owuyihlole, futhi ukusekelwa kwenketho kuyahluka phakathi kwazo. Bheka imibhalo yaleyo njini esikhundleni sokucabanga ukuthi zonke izinhlelo ezingenisa iphrofayela ziziphatha ngendlela efanayo.

Shintsha inhloso, hhayi umugqa kuphela

Uma iseva endala ephethwe yayithembele ngempela ekuhloleni ukuvumelana, bhala ukuthi yayiphoqelela umkhawulo muni ngaphambi kokuthuthukiswa. Ukugcina inketho eshayiwe indiva kuphrofayela entsha akukwazi ukulondoloza leyo nqubomgomo, futhi nokususa imigqa ngokungakhethi akukwazi.

Ungaphenduli esiphakamisweni esidala sokuthi konke ukubethela kukhutshaziwe ngokuvula yonke i-algorithm yomlando.

Ngemuva kokulungiswa okugunyaziwe, hlola imiphumela ekuxoxisanwe ngayo kuxhumano olusha futhi uhlole uhlelo oludingwa umsebenzisi ngempela. Gcina inguqulo yeseva kanye nenqubomgomo esebenzayo eduze kwalowo mphumela, ukuze umuntu olandelayo abone okuvunyelwene ngakho, hhayi kuphela okuwamukelwe.

Umgomo uwumkhawulo osekelwayo kanye nomzila oqinisekisiwe osebenzayo, hhayi ifulegi elidala elisahlaziywayo.
