Ukuxazulula Izinkinga Ezivamile

Iseva ye-DHCP ingenza izinto zibe lula; noma kunjalo, ungase ubhekane nezingqinamba eziphazamisa inethiwekhi noma zivimbele amadivayisi ukuthi angene ku-inthanethi. Izinkinga eziningi zivela lapho okuthile kuphazamisa isevisi ye-DHCP, kungaba inkinga yokucushwa, iphutha lezintambo, noma umzila wenethiwekhi. Kwabaningi bethu, uphawu lokuqala lwenkinga yilapho idivayisi ingeke ithathe ikheli le-IP noma lapho amadivayisi amabili elwela elilodwa. Lokhu kuyinkinga, kodwa kungaxazululeka ngendlela ehambisanayo kanye nesineke.

Okokuqala, qinisekisa ukuthi iklayenti neseva bayakwazi ukubonana ngempela. Kungaba izintambo ezimbi, amaswishi angaxhunywanga, noma amadivayisi avaliwe. Akukho ukulungiswa okuningi okuzokusindisa uma izintambo zivaliwe. Isibonelo, uma i-laptop ingaxhumani, yixhume kwenye imbobo noma usebenzise ikhebula elisebenzayo elaziwayo. Uma usuwazi ukuthi isixhumanisi esingokoqobo sihle, hlola ukuthi iklayenti neseva baku-subnet efanayo. Amaklayenti kwenye i-subnet adinga i- I-ejenti yokudlulisa ye-DHCP ilungiselelwe ku-router, noma abatholi ikheli labo le-IP. Ama-router awathumeli ukusakazwa okusetshenziswa yi-DHCP ngokuzenzakalelayo, ngakho-ke uma ushiya lesi sinyathelo, amanye amadivayisi azokhishwa.

Ukungqubuzana kwamakheli kungenye indlela yokudonsela phansi. Uma amadivayisi amabili esebenzisa i-IP efanayo, ayikho kuzo esebenza kahle. Lokhu kungenzeka uma othile esetha ngesandla i-IP engaguquki ehlangana ne-pool noma uma indima yeseva ye-DHCP ingavumelani. Hlola amalogi e-DHCP ukuthola izinkomba — lawa marekhodi ayimayini yegolide uma uzama ukubona ukuthi kwenzekeni nokuthi nini. Azokutshela ukuthi isicelo singenile yini, ukuthi siphenduliwe yini, nokuthi ngabe kukhona amaphutha, ngakho-ke kuwukuhlakanipha ukuwahlola njalo.

Ukuqonda izimo ze-dhcp—Ukuqalisa, Ukucela, Ukubopha, Ukuvuselela, Ukuphinda Ubophe—kungakusiza ekuboneni ukuthi zihlukana kuphi. Uma zibambelela ku-“Ukucela,” mhlawumbe une-network block noma iseva ihamba kancane kakhulu. Ukuqalisa kwe-PXE kungakhubeka ne-DHCP, ikakhulukazi emahhovisi lapho imishini izama ukuqala khona kunethiwekhi bese igcwalisa iseva ngezicelo ezingadingekile.

Ukuze kube lula ukuphatha, hlukanisa ama-subnet ngezixhumi ezingaphansi ukuqinisekisa ukuthi idivayisi ngayinye ithola ikheli elifanele. Landela umkhuba omuhle kakhulu, gcina ama-log akho, hlola kabili izilungiselelo zakho, futhi uma ungabaza, hlola njalo ngedivayisi entsha.

Isiphetho

Lawa matshe amancane yiwona agcina izinto zihamba kahle kunoma iyiphi inethiwekhi. Asikho isidingo sokulungiselela yonke idivayisi ngesandla—i-DHCP ikwenza ngokushesha futhi ngaphandle kokuphazamiseka. Kusukela ekuxhawulaneni kokuqala kuya ekulungiseni amaqhubu emgwaqweni, igcina wonke umuntu exhunyiwe. Izinyathelo zokuphepha eziqinile kanye nokwenza ngcono okuhlakaniphile kuqhuba i-DHCP nakakhulu. Cabanga ngesikole esinamakhulu ama-laptop noma isibhedlela esinemishini emisha njalo ngeviki—i-DHCP igcina lobu budlova bulawulwa. Noma ubani angayinika ithuba inethiwekhi yakhe ngokufunda lezi zisekelo namaqhinga. Ufuna ukugcina umphakathi wakho ushesha futhi uphephile? Thola, zama futhi uwugcine uthakazelisa. Amanethiwekhi ashintsha ngokushesha. Lungela, futhi ukucushwa kwakho kuzoqhubeka, akukho nkinga.
