Mhinduro Resolution Protocols inoshandisa nzira iyo nzvimbo dzepaI IP dzinogadziriswa pakati pemakombiyuta paunetaneti.
Munzira yaro yakajeka fungidzira iwe une kombiyuta yakafanana ne laptop uye iwe unoda kutaurirana ne Raspberry PI yako iyo yose yakabatanidzwa sechikamu chekutengeserana kwako kwepakati pebandaneti.
Iwe unogona kazhinji kuona kana Raspberry PI inowanikwa pane network kuburikidza nekuiita . Kana uchangobva kuvhara Raspberry PI kana kuedza chero hupi humwe hukama neRaspberry PI iwe uchave uchikanda chido chekugadziriswa kwekambani. Funga nezvazvo sechimiro chekubatana.
IAA inofanidza kero uye subnet masks emubati pamwe nekombiyuta inotarirwa. Kana izvi zvikafanana ipapo kero yakanyatsogadziriswa kumatare emunharaunda.
Saka izvi zvinoshanda sei?
Kombiyuta yako ichava ne cache yeA ARP inotanga kuwanikwa kutanga kuedza uye kugadzirisa kero.
Kana cache isina ruzivo runodikanwa kugadzirisa kero ipapo chikumbiro chinotumirwa kumashini ose ari mumutambo.
Kana ikakani pamutambo isina nzvimbo yeI IP iri kutsvaga ipapo ichangosiya chikumbiro asi kana iyo mishonga ine mutsara zvino ichawedzera mashoko ehurukuro inoshandiswa pane imwe cache ye ARP. Ichazotumira mhinduro kudzokera kumutambo wekudana wepakutanga.
Pakugamuchira kugutsikana kwekombikiti yekutsvaga kakombiyuta kubudiswa kunogadzirwa uye saka ping kana imwe yekumbira keseti inogona kushandiswa.
Mashoko chaiwo iyo kombiyuta inotsvaga iri kutsvaga kubva kumakombiyuta ari kuenda kune iyo MAC yero kana kana dzimwe nguva inonzi HW Address.
Muenzaniso Wakashanda uchishandisa Arp Command
Kuita izvi zvive nyore kukunzwisisa iwe uchada kuva nemakombiyuta maviri akabatanidzwa kumutambo wako.
Iva nechokwadi chokuti zvose zvemakombiyuta zvinoshandurwa uye zvinokwanisa kubatanidza neInternet.
Iye zvino vhura vheji rekugadzirisa uchishandisa Linux uye faira murairo inotevera:
arp
Mashoko aya anoratidzirwa ndeye ruzivo rwezvino rwakachengetwa muchengeti ye ARP yekombiyuta yako.
Zvigumisiro zvingangoratidza murwi wako, iwe haungatombooni kana zvachose zvingabatanidza zita reimwe kombiyuta kana wakabatana naro kare.
Ruzivo rwakapiwa neArp command runotevera:
- Address
- HW Type
- HW Address
- Flags
- Mask
- IFace
Kana usina chinhu chakaratidzika saka usazvidya mwoyo nokuti izvi zvichange zvichishandurwa pfupi. Kana iwe uchikwanisa kuona imwe kombiyuta ipapo iwe uchazoona kuti kero yeHW yakagadzirirwa (isina kukwana).
Iwe unofanirwa kuziva zita rekombiyuta yauri kubatanidza nayo. Mune mhaka yangu, ndiri kubatana neRaspberry PI zero yangu.
Pakati pemagetsi runza murairo unotevera uchishandisa mazwi raspberrypizero pamwe nezita remakombiyuta iwe urikubatanidza.
ping raspberrypizero
Chii chakaitika ndechokuti kombiyuta yauri kushandisa yakatarisa mu cache yayo yeAAR uye yakaona haina ruzivo kana kuti kwete ruzivo rwakakwana pamusoro pemichina yauri kuedza kuita ping. Saka yakatumira chikumbiro kune imwe yenhare vachikumbira mamwe mimwe mitambo iri mumusangano kana iri iyo kombiyuta yauri kutsvaga.
Pakombiyuta imwe neimwe yehutaneti ichaona paIndaneti uye mask akakumbira uye vose asi iyo iyo IP address icharasa chikumbiro.
Ikombiyuta ine kero yakakumbirwa IP uye maski ichadanidzira, "Hey ndini ini !!!!" uye inotumira kero yake yeWW kumashure yekombiyuta inokumbira. Izvi zvichazobva zvawedzerwa ku-ARP cache yemakirini ekudana.
Musanditenda ini? Runzai arp command zvakare.
arp
Panguva ino unofanirwa kuona zita remakombiyuta iwe waiona uye iwe uchaonawo kero yeHW.
Ratidza II IP Addresses Panzvimbo yeKubwinya & # 39; s Hostname
Nokutadza, mutemo weArp ucharatidza zita remubatanidzwa wezvinhu mukati meAAC cache asi unogona kumanikidza kuti ione IP mazita uchishandisa shanduko inotevera:
arp -n
Zvimwe, unogona kuda kushandisa shanduro inotevera iyo icharatidza kubuda nenzira yakasiyana:
arp-a
Izvo zvinobva mumurairo wepamusoro zvichava chimwe chinhu pamiganhu yeiyi:
raspberrypi (172.16.15.254) at d4: ca: 6d: 0e: d6: 19 [ether] pane wlp2s0
Panguva ino unowana zita remakombiyuta, IP address, HW kero, iyo HW uye network.
Nzira Yokubvisa Sei Makopinda Kubva kuAA Cache
Muchengetedzo weAA haubatisisi kudhidhiyo kwenguva yakareba asi kana uri nehurukuro dzinosangana kune imwe kombiyuta uye iwe unofungidzira kuti nokuti dhesi re data rakachengetwa rakashata iwe unogona kubvisa kuvhara kubva pane cache nenzira inotevera.
Kutanga, shandisai arp command kuti uwane kero yeHW yekupinda iwe unoda kubvisa.
Zvino chengeta murairo unotevera:
arp-d HWADDR
Dzorera HWADDR neHW Address yekupinda iwe unoda kubvisa.
Summary
Mutemo weArp hausiwanzoshandiswa nemushandisi wepakombiyuta yako uye zvichave zvakakosha kune vanhu vakawanda kana matambudziko ekubatanidza mitambo.
