Lapho lokho kuqondwa, umbuzo othakazelisayo uba ukuthi ngabe ukubhala kuphumelele ngempela yini.

Amadirectory amabili esikhashana, indlela eyodwa

Isilungiselelo sokwehlukanisa sinikeza iyunithi umbono oyimfihlo wamadirectory esikhashana esikhundleni sokuwenza afundwe kuphela. Izinqubo ezingaphandle kweyunithi azikwazi ukubona okubhalwayo lapho, futhi konke okushiwo kuyaphonswa lapho iyunithi ima. Ngakho-ke indlela ephrintiwe i-hook nendlela ehlolwe isuka ku-shell kungase kubhekisele ezintweni ezihlukene ezinagama elifanayo.

Lena yinkinga yokubonakala, futhi ibukeka njengenkinga yokulahlekelwa idatha. Akukho okucishiwe, ngoba ifayela likhona nje endaweni yamagama i-shell engeyona ilungu layo. Umyalo ofanayo uziphatha ngendlela ehlukile lapho usetshenziswa ngaphakathi kweyunithi, futhi lokho kubuka yikho okuvame ukuqeda impikiswano. Funda izilungiselelo zeyunithi ngaphambi kokuphetha noma yini mayelana nokubhala.

Ihlukanise okungabonakali nokungabhaliwe

Ukubhala okuphumelelayo nokuvula okwehlulekile kunikeza ubufakazi obuhlukene, futhi lowo mehluko unquma ukulungiswa. Uma i-hook ithi ifayela ladalwa kodwa umfundi wangaphandle akalitholi, unombuzo wendawo yamagama. Uma i-hook ibika iphutha lemvume noma ukuvula okwehlulekile, ifayela alibhalwanga neze futhi akukho shintsho lendawo yamagama elizosiza.

Indlela yempande yenqubo iveza umbono wesistimu yamafayela yesevisi uqobo, ngaphansi kokuhlolwa kwemvume kuleyo nqubo ngesikhathi isasebenza. Funda ijenele yeyunithi esikhaleni esifanayo, ngoba iphutha lokubhala nefayela elilahlekile kuvame ukudideka lapho othile esenqume imbangela kakade.

Nikeza idatha eyabiwe indawo ecacile

Idatha edingwa yisevisi kuphela isendaweni yayo yesikhashana eyimfihlo. Idatha okufanele ifundwe enye inqubo idinga indlela echazwe kuzo zombili, enomnini, imodi kanye nokuphelelwa yisikhathi okushiwo. Nquma ukuthi yikuphi kulezi zimo ezimbili onakho ngaphambi kokuhlela iyunithi. Iningi lalezi zigameko livela ekuthatheni ifayela eliyimfihlo njengelabiwe.

I-directory yesikhathi sokusebenza ibeka ifolda ngaphansi kwendawo yesikhathi sokusebenza yesistimu, iyidala yomsebenzisi neqembu elilungisiwe leyunithi, futhi iyisusa lapho iyunithi ima. Yengeza nge-drop-in ukuze iyunithi yephakheji ihlale iphelele, bese ulayisha kabusha umphathi futhi uqalise kabusha leso sikhathi, wamukele ukuthi amaklayenti ayo azoxhuma kabusha.

Gcina noma iyiphi i-directory yesikhathi sokusebenza eyudingwa yi-unithi efakiwe. Ukushintsha uhlu esikhundleni sokwengeza kuwo kuyindlela evamile yokuphula isici esingahlobene okungekho muntu okuxhumanisa nokushintsha.

Izingqimba ezimbili zamalungelo zingase zingavumelani

Umphathi wesevisi udala i-directory yomsebenzisi olungisiwe weyunithi, kuyilapho i-daemon ye-VPN ingase yehle ngokwehlukile iye ku-akhawunti yayo ngaphambi kokusebenzisa i-hook yokuxhumana. Lezi zingqimba ezihlukene, futhi zingase zibize ubunikazi obuhlukene.

I-directory ephethwe i-root enemodi evimbelayo ibonakala ngokuphelele ku-daemon eseyekile amalungelo, futhi ayikwazi ukubhalwa yiyo.

Qinisekisa ukunikezwa konke

Qinisekisa izinto ezine ngasikhathi sinye: i-hook ibhala ngaphansi kobunikazi bayo bangempela, umfundi ohlosiwe angakwazi ukusebenzisa ifayela, abasebenzisi abangahlobene abakwazi, futhi ukuma kweyunithi kuhlanza ngokohlelo. Ukuvela kwefayela ku-directory yesikhashana eyabiwe yomsingathi akusona isidingo, futhi ngokuvamile kuwuphawu lokuthi ukushintshana akukaze kuthole indlela yako.
