Iimpendulo zeeNkcazo zeeNkqubo zijongene nendlela idilesi ze-IP zendawo zixazululwa ngayo phakathi kweekhomputer kwintanethi.
Ngendlela elula kakhulu cinga ukuba unakho ikhomputha efana nekhompyutheni kwaye ufuna ukuthetha kunye ne-Raspberry PI yakho edibeneyo njengenxalenye yoxhumano lwakho lwengxowankulu yebhanki.
Ngokubanzi unokubona ukuba i-Raspberry PI iyatholakala kwinethiwekhi ngokuyifaka . Ngokukhawuleza xa ubeka i-Raspberry PI okanye uzame nayiphi na enye intsebenziswano kunye ne-Raspberry PI uza kukhaba isidingo sokusombulula idilesi. Cinga nje ngoluhlobo lwe-handshake.
I-ARP ikuthelekisa idilesi kunye nemaski e-subnet yomphathi kunye nekhompyuter ejoliswe kuyo. Ukuba ezi zidibaniso ke idilesi isisombululo ngokufanelekileyo kwi-network network.
Ngoko le nkqubo isebenza njani?
Ikhompyutheni yakho iya kuba ne-ARP cache efikelelwe kuqala ukuzama nokulungisa idilesi.
Ukuba i-cache ayinalo ulwazi olufunekayo ukulungisa idilesi kwaye isicelo sithunyelwa kumatshini ngamnye kwinethiwekhi.
Ukuba umatshini kwinethwekhi engenawo idilesi ye-IP ecatshangelwayo ngoko uya kuhoywa isicelo kodwa ukuba umatshini unomdlalo ngoko uya kwongeza ulwazi lwekhomputha yocingo kwi-ARP cache yayo. Kuya kuthumela impendulo kwi-computer yocingo yokuqala.
Emva kokufumana isiqinisekiso sedilesi yekhompyutheni ekujoliswe kuyo, ukuxhunywa kwenziwa kwaye ngoko-ke isicelo se-ping okanye esinye senethiwekhi singacutshungulwa.
Ulwazi oluchanileyo umthombo wekhomputha owufunayo ukusuka kwikhompyutheni yokuya kuyo idilesi yayo ye- MAC okanye ngezinye iixesha ibizwa ngokuba yi-HW Idilesi.
Umzekelo oSebenzayo usebenzisa i-Arp Command
Ukwenza oku kube lula ukuqonda kuya kufuneka ukuba ube neekhomputer ezimbini eziqhotyoshelwe kwinethiwekhi yakho.
Qiniseka ukuba zombini iikhomputha zitshintshile kwaye ziyakwazi ukuxhuma kwi-intanethi.
Ngoku uvule iwindi yokugcina usebenzisa i-Linux uze uthayiphe umyalelo olandelayo:
i-arp
Ulwazi oluboniswe lulwazi olugcinwe kwikhompyutheni ye-ARP yekhompyutha yakho.
Iziphumo zinokubonisa umatshini wakho, awunakuboni nantoni na okanye iziphumo zingabandakanya elinye igama lekhomputha xa udibanise ngaphambili.
.Ulwazi olunikezwa ngumyalelo we-arp lulandelayo:
- Idilesi
- Uhlobo lwe-HW
- Idilesi yeHW
- Iiflegi
- Mask
- IFace
Ukuba akukho nto ibonakalisiweyo ke ungakhathazeki kuba oku kuya kutshintshwa kungekudala. Ukuba ungabona enye ikhomputha ngoko uya kubona ukuba idilesi ye-HW isethelwe (ayizalanga).
Udinga ukwazi igama lekhompyutha oxhuma kuyo. Kwimeko yam, ndidibana ne-Raspberry PI zero yam.
Ngaphakathi kwesi sigqeba uqhuba umyalelo olandelayo endaweni yegama elithi raspberrypizero negama lekhompyutha odibanisayo kuyo.
ping raspberrypizero
Yintoni eyenzekayo kukuba ikhompyutha oyisebenzisayo iye yajonga kwi-cache yayo ye-ARP kwaye yaqonda ukuba ayinalo ulwazi okanye ayinalo ulwazi olwaneleyo ngomatshini ozama ukuwasebenzisa. Ngoko-ke ithumele isicelo phakathi kwenethiwekhi ukucela bonke abanye oomatshini kwinethiwekhi ukuba ngaba ngokwenene ikhomputha oyifunayo.
Ikhomputha nganye kwinethiwekhi iya kujonga idilesi ye-IP kunye ne-mask eceliwe kwaye bonke kodwa idilesi ye-IP iya kulahla isicelo.
Ikhomputha ene-IP idilesi eceliwe kunye nemaski iya kukhwaza, "Hayi mna!" kwaye uzothumela idilesi yayo ye-HW kwisicelo sekhompyutha. Oku kuya kufakwa kwikhompyutheni ye-ARP yekhomputha yokubiza.
A ndi kholelwa? Qalisa kwakhona umyalelo we-arp.
i-arp
Ngeli xesha kufuneka ubone igama lekhompyutheni oyiphakamisayo kwaye uza kubona idilesi ye-HW.
Bonisa iIkheli ze-IP endaweni yekhompyutheni ye & Computer;
Ngokungagqibekanga, umyalelo we-arp uza kubonisa igama lomninimzi wezinto kwi-cache ye-ARP kodwa unokunyanzelisa ukuba ubonise iidilesi ze-IP usebenzisa umtshintsho olandelayo:
i-arp -n
Ngaphandle koko, unokuba unqwenela ukusebenzisa umtshintshi olandelayo oza kubonisa isiqhamo ngendlela ehlukileyo:
i-arp -a
Isiphumo esivela kumyalelo ongentla siya kuba yinto elandelayo kule migca:
i-raspberrypi (172.16.15.254) kwi-d4: ca: 6d: 0e: d6: 19 [ether] kwi-wlp2s0
Eli xesha ufumana igama lekhompyutha, idilesi ye-IP, idilesi ye-HW, uhlobo lwe-HW kunye nenethiwekhi.
Indlela Yokucima Iingeniso ezivela kwi-ARP Cache
I-cache ye-ARP ayibambeli kwidatha yayo ixesha elide kodwa ukuba unemiba edibanisa kwikhompyuthile ethile kwaye uyakrokrelwa kukuba idatha yedatha egcinwe ayilungile unokucima ukungena kwi-cache ngendlela elandelayo.
Okokuqala, sebenzisa umyalelo we-arp ukuze ufumane idilesi ye-HW yokungena ofuna ukususa.
Ngoku ugijime umyalelo olandelayo:
i-arp -d HWADDR
Misela i-HWADDR nge-HW Idilesi yokungena ofuna ukukususa.
Isishwankathelo
Umyalelo we-arp awunasetyenziswa ngokuqhelekileyo ngumsebenzisi wakho wekhomputha kwaye uza kuba neyona nto ebalulekileyo kubantu abaninzi xa kunokujongana neengxaki zenethiwekhi.
