I-VPN yaselabhu ixhunyiwe, kodwa ithuluzi lesifundo lisawehluleka

I-VPN yokuqeqesha inikeza indlela yamaphakethe; ayiqinisekisi ukusekelwa kwethuluzi laselabhu. Hlola umugqa oyisisekelo wesifundo, bese kuba ifayela le-binary kanye nemitapo yalo.

I-VPN ithi ixhunyiwe, umgomo wesifundo uphendula i-ping, kodwa ithuluzi laselabhu lisaphuma nephutha. Le nhlanganisela ivamile ezindaweni zokuqeqesha, ngoba umhubhe nendawo yokusebenza esekelwe yizinto ezimbili ezihlukene. Okunye kuqinisekisa indlela yamaphakethe; okunye kuqinisekisa ukuthi uhlelo lungasebenza kule ngingqondo noma ngalutho. Uma uthatha ukwehluleka njengenkinga ye-VPN, uzoya kushintsha izilungiselelo zenethiwekhi ezingakaze zibe nokungalungile.

Isibonisi sokuxhunyaniswa siqinisekisa ini ngempela

Ukuxhumana kwe-VPN kuqinisekisa ukuthi iklayenti lafika esangweni futhi lathola umzila nokwabiwa kwamakheli. Akusho ukuthi imaphi amachweba azodingeka kamuva emsebenzini, ukuthi ithuluzi lihambisana nohlelo lokusebenza, noma ukuthi isakhiwo salo nemitapo yalo zikhona. Lokho kungamaqiniso ohlelo. Uma ukuhlolwa okuyisisekelo kwesifundo kudlula kanti ithuluzi lisawehluleka, umbuzo osele ukuhambisana, hhayi ukuxhumana.

Bhala ukuthi ikuphi kokubili okuhlola ngempela, ngoba ibheji yokuxhunyaniswa kulula ukuyithatha ngokungeyikho njengobufakazi bakho kokubili.

Qala ngokuhlola indlela ebhaliwe yesifundo

Sebenzisa ukuhlolwa okushicilelwe uthisha, kusukela kumshini ofanayo noma endaweni yokusebenza eqhuba umsebenzi. Lokho kugwema ukuhlola indawo ehlukile bese uyibiza ngokuthi iyalingana.

Ukusesha komzila kubonisa ukuthi yiluphi uxhumano umgudu wesifundo ongawusebenzisa, futhi ukuhlolwa kwechweba kubonisa ukuthi leyosevisi ethile iyakwamukela yini ukuxhumana. Umzila okhomba exhumaaneni elingalungile uchaza ukwehluleka, kuyilapho ichweba elenqatshiwe elinomzila olungile likhomba kusevisi noma kunqubomgomo yayo. Shintsha amakheli ayisibonelo ngohlu lwemigomo olwabiwe, futhi bhala ikheli lomthombo elasetshenziswa ukuhlolwa. I-ping kwenye ingingqondo esohleni ayilona uhlolo olufanayo.

Bese uhlola ithuluzi ngokumelene ne-matrix yokusekelwa

Uma indlela isiqinisekisiwe, hlola uhlelo olugqutshwa ngempela umsebenzi. Ukungahambisani kwesakhiwo nemitapo kwehluleka ngomsindo futhi kulula ukukufunda ngokungeyikho njengokuphelelwa isikhathi.

Uhlobo lomshini lutshela ukuthi yiziphi izinhlobo ze-binary ezingasebenza, umbiko wefayela ubiza ifomethi nesakhiwo sethuluzi, futhi uhlu lwemitapo lubonisa ukuthi ukuncika kuyaxazululwa yini. I-binary yamabhithi angu-32 esithombeni samabhithi angu-64 kuphela, noma umtapo owabiwayo ongekho, kukhiqiza iphutha elingenasihlobo nomhubhe. Qhathanisa ukukhishwa neplathifomu ne-matrix yokusekelwa yesifundo, hhayi nokuthunyelwe kwenkundla mayelana nolunye uhlobo. Gcina imvume yomsebenzi ingashintshile ngenkathi uqoqa lobu bufakazi.

Nikeza umnikazi izitholakele ezimbili ezihlukene

Ukusekelwa kokuqeqesha kungasebenza ngokwehlukaniswa okucacile: lokho umugqa oyisisekelo wenethiwekhi okubonisile nalokho indawo yethuluzi ekubonisile. Faka imiphumela ehlanjululwe yomzila nechweba, umbhalo wamaphutha oqondile kanye nemininingwane yeplathifomu evela ekuhlolweni kwe-binary. Shiya ngaphandle ubufakazi bokungena nemigqa yokumisa eyimfihlo, okwengeza ingozi ngaphandle kokusiza ukuxilongwa. Bese uyeka umnikazi anqume ukuthi alungise indawo noma alungise umsebenzi, futhi ungandisi uhlu olwabiwe futhi ungaboleki umshini womunye umhlanganyeli ukuze uqinisekise iphuzu.

Bhala izitholakele zombili kuthikithi ngisho nalapho eyodwa kuphela iyimbangela. Lapho-ke umzamo olandelayo uqala ngobufakazi hhayi ngomqondo.
