Ikheli elizinzile likuthengela ini

Ikheli lomhubhe eliqhubekayo ligcina imithetho yangaphakathi namabhukhimakhi eqondiswe kukhasimende ofanayo, okubalulekile lapho uphatha inethiwekhi yomuntu siqu encane. Ukuphuma komphakathi okuqhubekayo kugcina uhlu lwemvume lwangaphandle lusebenza ngaphandle kokuhlelwa, okubalulekile lapho uhlelo lokusebenza lukazakwethu lumukela imithombo eyaziwayo kuphela. Lezi zinto zokuthenga ezihlukile, ezithengiswa ngamazwi afanayo. Buza ikhasi losizo ukuthi yikuphi kulokhu okubili iphakethe eliqinisekisa ngempela.

Umhlinzeki angakhipha ikheli lomhubhe wangasese elifanayo kukho konke ukuxhumana ngesikhathi eqondisa ukuphequlula ngeqoqo lokuphuma elijikelezayo. I-akhawunti ibonakala imile kukhasimende futhi iziphatha ngokushintshayo ku-inthanethi. Qinisekisa ohlangothini olusebenzisa umthetho, hhayi ohlangothini oluchaza wona.

Ukuqhubeka nokukhethekile kuyizethembiso ezihlukile

Ukuphuma okwabiwe kungagcina ikheli elilodwa iminyaka ngesikhathi amakhulu e-akhawunti elisebenzisa, ngakho ukuqhubeka nokukhethekile kuyizethembiso ezihlukene.

Ukwabiwa kusetshenziswa futhi isikhashana, ngakho ukubona inani elifanayo izikhathi ezintathu ubufakazi mayelana nalokho kubona okuthathu futhi akukho okunye, ngoba izinga lokuphindeka liyizibalo ngeqoqo hhayi isethembiso. Buza ukuthi ukushintshwa kumenyezelwa kanjani, nokuthi uhlelo lokusebenza kufanele lwenzeni ngesikhathi umhubhe ungekho.

I-DNS eshintshayo ifanele kuphi futhi igcina kuphi

I-DNS eshintshayo igcina igama lesibungu likhomba ekhelini elishintshayo, okukusiza ukuthola iseva yasekhaya ngemva kokuba umugqa usushintshe inombolo.

Qinisekisa ukuthi uhlangothi olude lubona liphi ikheli

I-kernel izokutshela ukuthi ihlose ukusebenzisa liphi umthombo endaweni ethile, futhi isixhumi somhubhe sizokutshela ukuthi sigcina liphi ikheli. Qhathanisa kokubili nalokho okubhalwa uhlelo lokusebenza olukude ngaphambi kokushintsha noma yiliphi iphakethe.
