Yog tias kuv upload ib cov ntaub ntawv, kuv lub computer yuav yog tus qhov chaw thiab lub server yuav yog tus qhov chaw . Cov qhov chaw yog lub kaw lus xa cov ntaub ntawv; tus qhov chaw yog qhov system txais cov ntaub ntawv. Hauv cov ntaub ntawv aunidirectional ntws, koj yuav pom (kuj) cov pob ntawv loj los ntawm ib qho kawg, nrog tcp.
Hauv qhov no, qhov chaw thiab qhov chaw IP chaw nyob yog dab tsi?
Cov qhov chaw IP chaw nyob yog tus xa, thiab chaw nyob IP chaw nyob yog lub hom phiaj txais. Devices uas tsim lub network siv lub chaw nyob IP chaw nyob , thiab tej zaum ib co lwm yam, xa cov pob ntawv hla lub network.
Ib yam li ntawd, kuv yuav ntxiv cov ntxaij lim dej hauv Wireshark li cas? Txhawm rau siv cov ntxaij lim dej:
- Ntaus ip.addr == 8.8.8.8 hauv lub thawv lim thiab nias Enter.
- Ua tib zoo saib tias Cov Ntawv Teev Npe Pane tam sim no tau lim kom tsuas yog taug kev mus rau (qhov chaw) lossis los ntawm (qhov chaw) IP chaw nyob 8.8.8.8 tau tshwm sim.
- Nyem Clear ntawm Filter toolbar kom tshem tawm cov teeb pom kev zoo.
Tsuas yog li ntawd, qhov chaw nres nkoj qhov chaw nres nkoj yog dab tsi?
Qhov chaw chaw nres nkoj ua hauj lwm analogues qhov chaw nres nkoj , tab sis yog siv los ntawm tus tswv tsev xa mus pab kom taug qab cov kev sib txuas tshiab thiab cov ntaub ntawv uas twb muaj lawm. Raws li koj feem ntau paub zoo, hauv TCP / UDP cov ntaub ntawv sib txuas lus, ahost yuav ib txwm muab ib qho qhov chaw thiab qhov chaw tus lej xov tooj.
Kuv yuav ntxiv qhov chaw nres nkoj hauv Wireshark li cas?
Txhawm rau hloov cov txheej txheem cuam tshuam nrog lub chaw nres nkoj:
- Qhib wireshark.
- Mus rau Kho kom raug -> Preferences -> Protocols.
- Nrhiav koj tus txheej txheem thiab nyem rau nws.
- Nyob rau sab xis koj yuav tsum pom cov npe ntawm cov chaw nres nkoj xav tias yuav siv cov txheej txheem.
- Txhawm rau ntxiv koj tus kheej qhov chaw nres nkoj, tsuas yog ntxiv lub cim "," tom qab qhov chaw nres nkoj kawg tau teev tseg thiab nkag rau koj tus kheej.

Qhov chaw nyob IP twg raug muab ua qhov chaw nyob ntiag tug?
Tus IPv4 chaw nyob RFC1918 lub npe IP chaw nyob ntau Tus lej ntawm qhov chaw nyob 24-ntsis thaiv 10.0.0.0 - 10.255.255.255 16777216 20-ntsis thaiv 172.16.0.0 - 172.31.255.255 block 104.65.6 2018.25.65
Qhov txawv ntawm qhov chaw nyob thiab qhov chaw nyob yog dab tsi?
Qee zaum, 'txoj kev chaw nyob' hais txog koj lub cev qhov chaw nyob ntawm qib zoo dua hauv nroog. Piv txwv li, '1313Mockingbird Lane', tsis muaj lub nroog lub npe txuas nrog. Tab sis yog, feem ntau nws tsuas yog ib daim ntawv rov qab kom paub qhov txawv ntawm qhov chaw xa ntawv (thaum chiv keeb) thiab tam sim no e-mail chaw nyob, chaw nyob hauv web, IPaddress, thiab lwm yam
Qhov chaw nyob ntawm lub cev thiab qhov chaw nyob qhov chaw nyob yog dab tsi?
Qhov sib txawv yooj yim ntawm Logical thiab lub cev chaw nyob yog qhov chaw nyob Logical yog tsim los ntawm CPU hauv kev xav ntawm ib qho kev pab cuam. Ntawm qhov tod tes, qhov chaw nyob ntawm lub cev yog qhov chaw nyob uas muaj nyob hauv lub cim xeeb. Cov txheej txheem ntawm txhua qhov chaw nyob uas tsim los ntawm CPU fora program hu ua Logical Address Space
Dab tsi yog qhov chaw nyob thiab lub cev nyob hauv OS?
Qhov sib txawv yooj yim ntawm Logical thiab lub cev chaw nyob yog qhov chaw nyob Logical yog tsim los ntawm CPU hauv kev xav ntawm ib qho kev pab cuam. Ntawm qhov tod tes, qhov chaw nyob ntawm lub cev yog qhov chaw nyob uas muaj nyob hauv lub cim xeeb. Cov txheej txheem ntawm txhua qhov chaw nyob uas tsim los ntawm CPU rau ib qho kev pab cuam hu ua Logical Address Space
Qhov txawv ntawm qhov chaw nyob sib txuas lus thiab qhov chaw nyob ruaj khov yog dab tsi?
Qhov chaw nyob xa ntawv yog chaw nyob sib txuas lus piv txwv li qhov koj nyob tam sim no. & chaw nyob Apermanent yog ntawm koj cov ntaub ntawv yog sau rau ntawm koj daim ntawv pov thawj hnub yug & daim npav pov npav. Qhov chaw nyob ruaj khov & kev sau ntawv yuav zoo ib yam lossis txawv ntawm cov ntaub ntawv siv tau
