Kwama - yintoni na le nto? Iintlobo lock, umgaqo amanyathelo

"Unxibelelwano" iquka iikhompyutha kunye izixhobo ezininzi, kwaye omnye wabo - wesango. Yintoni leyo? Zeziphi iintlobo ezahlukeneyo? Yintoni Umgaqo wabo yesenzo?

Yintoni Gateway

Eli gama uye umzila yentsimbi, kwakunye software esetyenziswa ukudibanisa uthungelwano computer. Xilaveko kukusetyenziswa elandelwayo iintlobo ezahlukeneyo (umz, kwingingqi okanye kwihlabathi jikelele). Ukuqaphela kwesango kusetyenziswa imaski. Le into ebonakalisayo eyahlukileyo kuthungelwano lwehlabathi. Kukholelwa ukuba kwesango efakiweyo, ukuba kukho ukudluliselwa luncedo ukusuka kwindawo umbono lwe data ngomsebenzisi.

Yintoni imvelaphi yakhe

Gateway uqhuba ukuguqulwa protocol ukusuka uhlobo olunye ukuya kolunye. Umzekelo omhle kunjalo xa uqhagamshele kwikhompyutha wengingqi kunye uthungelwano lwehlabathi. Emva koko, usebenzisa i yesango womnatha. Ukuba bangenise umzekelo yentsimbi, Ndikubekela ukujonga into enye. A umzila (umzila), zithandwa kakhulu kwaye esetyenziswa yi isixhobo - kuba ngesango iintsimbi efanayo. Bayakwazi ukusebenza zonke iinkqubo ethandwayo yokusebenza. Main, olwenziwa ngumsebenzi womnatha gateway - ukuguqula iprotocol phakathi uthungelwano ezahlukeneyo. Ngoko ungafumana, inkqubo ze uthumele iipakethi. Ngaphezu koko, ukudluliswa kwedatha iya kwenziwa ibe protocol enye, kwaye nje ezimbalwa.

Kwama - ezi zifundo zeenkqubo zobugcisa na kwenziwa hardware okanye isoftware izisombululo, okanye idityaniswe kunye (ukuba kwenzeka amaninzi). Kodwa ngokuqhelekileyo ngaphantsi kwawo athetha izicelo ezifakwe kwi zendlela kunye / okanye ikhompyutha. Kwama - zizixhobo ekufuneka ukuqonda yonke imithetho elandelwayo ukuze adlulisele data. Kufuneka bakwazi ngemfihlo kwaye ukucazulula zonke sifunyenwe kwaye wathumela ulwazi. Ethetha iintsilelo zokuphuma nokungena, kufanele kuphawulwe ukuba basoloko kakhulu ingacota kunendlela eqhelekileyo imizila, itshintshela kunye iibhulorho womnatha. Baya inokufana node okanye uyayiphelisa indawo yayo kwi Internet. Ethetha elidlulileyo, kuyimfuneko ukuba ukwahlula phakathi wemikhosi kunye kuphuma. Oku kubaluleke kakhulu. Ngoko ke, qala ukunika abasebenzisi a iikhompyutha iphepha le web, kwaye eyesibini - ukuqhagamshela uthungelwano ezahlukeneyo. Le yokugqibela ziquka server olulawula neyentengiso kwi unxibelelwano phakathi kweekhompyutha zenkampani kunye Internet. Xa imiqulu elikhulu Gateway uqobo kuhlanganiswe firewall kunye nendawo proxy. Kuba ekulawuleni ukuhanjiswa kunye nokuguqulwa kwathunyelwa ke ubudlelane bethu bunaye umzila. Ukuba sithethe software, oko sifakelwe zombini ku mncedisi engakhethwanga kwaye kwi computer.

imisebenzi yesango

Useka a iindlela ukudluliselwa packet data lwenjongano womnatha owahlukeneyo ezahlukeneyo. Kwakhona ukwenza kwasendaweni zonke iimoto zigqithiswe. Subnet inokuba yesango okanye ijelo data. Kwakhona, kukho inkalo ethile ayikho kodwa kwandile. Ke kaloku, wayethetha ngesango ilizwi. Kuyimfuneko ukuba adlulisele traffic odiyo. Voice Gateway kusetyenziswa phones.

isimiso ukusebenza

ingenzeka njani konke? Kwama - isixhobo ukuba ingaqalisa kuzo zonke iindlela ezaziwayo yokusebenza. Yena uya kuphonononga indlela ixesha data xa umsebenzisi ecofa i "Submit" iqhosha. Okokuqala kukho ingcaciso usebenzisa ulwimi kumatshini ukuba khompyutha kufuna. Ke lonke ulwazi code yi ikhowudi yokubini. Yahlulahlulwe yaba iipakethi data. Ngamnye kubo iqulathe ulwazi inxalenye oko kwaye apho ufuna. Encryption olwenziweyo. Emva koko, isigqibo indlela, kunye iipakethi data zithunyelwa kumamkeli. Xa efika apho aya khona, emva koko makayifake i-nkqubo ezichazwe apha ngentla ukuze reverse, ngaphandle ukuba khowudi yasiwa kumbhalo luyenziwa. Oko kukuthi, ifowuni isebenza kumzila yesango. Ngoku makhe sikhangele ukuba yintoni na iintlobo ezahlukeneyo kuphuma.

Default Gateway

Imizuzu kwesihloko kwidilesi apho zonke izithuthi ithunyelwe, kuba ezenza kube nzima ukwenza i ndlela. Kuba le ndawo kubhaliwe ikwabizwa ngokuba kwesango yokugqibela. Ukuze ubone apho ukuthumela i data usebenzisa itafile yomgudu okhethekileyo. Ukuba injongo ephambili alinikwa kunokwenzeka, badlula kuye. kwama Isicelo yokuncamela ezifumaneka networks apho imizila ezichazwe kakuhle core, ukuba namacandelo client zabo, kwakunye ubukhulu omncinane. Itafile, wabeka irekhodi: «0.0.0.0 network ezizenza 0.0.0.0». Kulungiselelwa esangweni le - akukho nzima (oko kudla ilungiswe ngexesha lofakelo abaqhubi).

yesango call

Xa phambili, esithi ukuba akukho lisetyenziswa IDT. A phawu uphawu kwesango kukuba iye endle WC. Ngoko ke, kunokwenzeka ukuba adlulisele kanye Februwari ⁵ = 32 amagama inkqubo ebizwa ngalo mfumba.

ingxaki gateway

Ingenelo ebalulekileyo kukuba yokusebenza kwalo - isebenze ngazo zontathu iitafile yokuchaza. Kodwa ke oko akuthethi ukusebenzisa intsimi imbaxa, ukuze bakwazi ukuthatha nayiphi na ixabiso. Kwakhona, njengoko kwicandelo ifunyanwa isicelo TSS. Kulungiselelwa kwesango, nangona yokusebenza kwalo, - hayi nto ilula.

yesango kumiswe

Oku kusetyenziswa kuphela kwi IDT. Kunokuba ziphazamise iflegi UKUBA kwakhona xa ungena inkqubo elihambisayo. Ekubeni ixabiso sangaphambili irejista usinde kule mfumba xa Uphumile ukusuka umsebenzi owenziwayo, kuthatha indawo yayo yoqobo. Ingenelo ebalulekileyo kukuba kwesango ingaphatha yinxalenye okuphazamisa ukuba kwenzeka imo cli.

traps yesango

Yena, naye, isetyenziswa kuphela kwi IDT. Ngelo xesha ke wawongwa isihloko yesango elula. Ngoko ke, xa kokuphazamiseka wafika, angaba uya inkqubo elihambisayo. Ukuba kuyimfuneko, oko nokuba mawenziwe iswitshi ntshunxekile. Makhe sihlolisise omnye thaca kwi iisampuli nqaku.

iimpawu ezongezelelweyo usebenzisa yesango olungagqibekanga

Ngokubanzi, yintoni na, yaye yintoni indima ukudluliselwa data? Ngaphezu kokuba ebonisa ithuba omnye kuphela, kodwa oko akuthethi anike ingcamango ngokupheleleyo oko nendlela. Ngoko ke, ngokuba yesango olungagqibekanga likuvumela ukuba lula uququzelelo yezithuthi. Njani? Ukuze wenze oku, ithumela yonke idatha ifunyenwe kwi imizila ezingundoqo, oko kubonakala ngakumbi "bulk" ukupeyinta, kwaye ngokufanelekileyo - banalo ithuba elikhulu ukufumana kumamkeli. Kwakhona qaphela oko itafile yomgudu wedesktop. Ngoko ke, ukuba unalo ndzhendzheleko, icandelo womnatha nokuthathwa ngesango olungagqibekanga. Indima yokugqibela - ukufumana zonke izithuthi, ezo nto kujongwana ezimbini umamkeli kuqala. Xa izixhobo ezininzi okanye izijungqe isixhobo eqhagamshelwe umzila enye, ukusetyenziswa yesango olungagqibekanga - kuphela indlela ekhoyo of ecacisa idilesi data. Xa usebenzisa le fomu uxhulumaniso ezininzi data Exchange ulahlekelwa intsingiselo yalo. Kulo mzekelo ngesango yokuziphatha isicwangciso kokumiyo ukuba yokuzikhethela.

Kutheni igama onjalo

kuza njani? Kufuneka kuqatshelwe ukuba isicelo kuyahlukana nedlela kwindawo, nangona kungekho umahluko ukusebenza hayi. Igama elithi "isango kokumiyo ukuba" kusetyenziswa workstations. ukusetyenziswa kwayo kula macala kwindlela eqhelekileyo yokusebenza ye iiyunithi. Igama elithi "isango yokuncamela" lisetyenziswa ezimalunga imizila apho isenzeko meko kuthathwa ukuba ungabi eqhelekileyo, ngokuba le fowuni kufuneka wazi kuhlala apho ufuna ukuhambisa iipakethi ulwazi.

isiphelo

Ukushwankathela, ukuba uthi uvalela isihloko capacious kakhulu. Ukuba osa isandla sakho kuzo ukuchaza ngokweenkcukacha indlela nento kubo, nkqu okubhaliweyo incinane ukuba kugqithisela Ubukhulu nqaku. Kodwa kwinqanaba eneenkcukacha loo ntetho ayide mfuneko kubasebenzisi eziqhelekileyo kwanabo configures kubo. Ufuna le nkcukacha kuphela xa loo mntu ngokwakhe efuna ukuphuhlisa sixhobo, kodwa kukho umbandela kufuneka ubhale incwadi yonke.
