Iphutha 720 le-VPN ku-Windows: iqoqo lamakheli noma ukuxhumeka kwekliyenti?
Iphutha 720 lisho ukuthi ukuxhumana akukaze kuthole ikheli elisebenzisekayo. Hlukanisa ukwehluleka kwesokhukho esisodwa nokwehluleka kwamasokhukho amaningi ngaphambi kokufaka kabusha i-adaptha.
Iphutha 720 livela ngemva kokwamukelwa kobufakazi, yingakho libuyisela abantu emkhakheni wephasiwedi. Ukuxhumana kufinyelele endaweni okuxoxwanwa ngayo ngekheli futhi akutholanga nelilodwa. Ukwehluleka okubili okuhluke ngokuphelele kukhiqiza ibhokisi elifanayo: iseva ibingenalutho lokwaba, noma le kliyenti ayikwazanga ukuqeda ukuxoxa. Ukuhlukanisa lezi ezimbili ngaphambi kokuthinta noma yini ingxenye enkulu yokulungisa, futhi lokhu kuhlukanisa kubhalwe ku-khasi lokuxazulula izinkinga lephutha 720 le-Microsoft.
Lokho okungakushiwo yibhokisi lokuxoxa
Umlayezo uchaza ukwehluleka ekuxoxeni kwe-PPP, futhi ngamabomu awucaci ngoba ikliyenti ayikwazi ukubona ukuthi kungani iseva inqabile. Akulona iphutha lobufakazi, futhi akusona isitatimende ngokubethelwa komgudu. Kusho ukuthi ikheli noma amapharamitha okuxoxa awazange alethwe.
Ohlangothini lweseva, imbangela evamile ukwabiwa: iqoqo eliqinile le-RRAS elingenamakheli akhululekile, noma ukulungiselelwa kwe-DHCP okuphelele noma okungafinyeleleki, kukhiqiza kanye lesi sibonakaliso kukho wonke ikliyenti elizamayo. Ohlangothini lwekliyenti, imbangela evamile ukuxhumeka. I-WAN Miniport ethwala i-PPP kufanele ixhunywe nezingxenye ezifanele, futhi ukuxhumeka okuvaliwe noma isihlungi senethiwekhi esifakiwe kungamisa ukuxoxa ngaphandle kwenkinga yedivayisi ebonakalayo. Le mindeni emibili idinga ubufakazi obuhlukile, futhi indlela eshesha ukukhetha phakathi kwazo ukubala ukuthi bangaki ikliyenti abathintekile.
Qala uhlukanise inani labantu, bese kuba yiqoqo
Bala amakliyenti athintekile ngaphambi kokufunda noma yikuphi ukulungiselelwa. Ukwehluleka okushaya wonke umuntu ngesikhathi esisodwa yisimo seseva, futhi ukwehluleka okulandela umshini owodwa phakathi kwenethiwekhi yisimo sekliyenti. Lokho kubala kubiza umlayezo owodwa esiteshini sengxoxo futhi kusindisa intambama.
| Artifact | How you get it | What it rules out | What it cannot rule out |
|---|---|---|---|
| Affected-client count | One message to the people who failed, or a search of today's tickets | A client-only fault, when every client failed within minutes | Which server-side component stopped allocating |
| RRAS event for one attempt | Get-WinEvent on the System log, filtered to the allocation event id | An allocation failure, when no event matches that attempt | A binding fault that appears later in the same negotiation |
| Hidden WAN Miniport bindings | Get-NetAdapter with hidden adapters, then the binding list on the returned name | A disabled ms_wanarp binding or an inserted filter on this client | Pool exhaustion that would also have hit other clients |
| Free-address count | The RRAS pool view, or the DHCP scope statistics | A committed static range or an exhausted scope | Why the address was not delivered to one specific client |
Bese uhlobanisa umzamo owodwa ohlulekile nerekhodi leseva uqobo, ngoba i-RRAS irekhoda umcimbi uma ingakwazi ukwaba futhi lowo mcimbi usho ukwehluleka hhayi isibonakaliso. Uma ukwehluleka kulandela ikliyenti ethile, ilogi yeseva ngeke ikhombise lutho ngalowo mzamo, futhi lokho kuyafundisa ngokwako. Ukungabikho kwephutha lokwaba kunciphisa inkinga ekuxoxeni kulelo kliyenti futhi kukutshela ukuthi yimiphi imiyalo okufanele uyisebenzise ngokulandelayo.

Get-NetAdapter -IncludeHidden | Where-Object { $_.InterfaceDescription -like "WAN Miniport*" }Funda isimo sokwabiwa kweseva
Ohlangothini lwe-RRAS, qinisekisa ukuthi iyiphi indlela yokwaba elungiselelwe ngempela hhayi leyo umqulu oyicabangelayo. Iqoqo eliqinile nokulungiselelwa okudluliswa nge-DHCP kuyahluleka ngezindlela ezihlukile, futhi ukulungisa kungokwalokho okusetshenziswayo. Ukuze uthole iqoqo eliqinile, bala amakheli akhululekile bese ufuna ukwabiwa komsebenzisi ngamunye okubamba isivumelwano sokugeshwa okungekho muntu okhumbulayo ukuthi senziwe, ngoba iqoqo elibonakala likhulu lingagcwele ngokuphelele. Nge-DHCP, hlola ukuthi isidluliseli sifinyelela iseva nokuthi ububanzi bunezivumelwano ezikhululekile.
Ububanzi obuqedwa amakliyenti ajwayelekile bukhiqiza i-720 efanayo neqoqo elilungiselelwe kabi, futhi ikhonsoli ye-RRAS izobonakala iphilile ngokuphelele kuzo zombili izimo. Phikisa ikhambi lefa lokwehlukanisa iqoqo libe yizigaba ezincane: iseluleko sokuqala sasichaza umphumela womphathi oyedwa, futhi asilungisi ukwehluleka kokwaba okungachazwa ngokuqondile imicimbi yeseva uqobo.
Funda ukuxhumeka kwekliyenti ngaphandle kokukwephula
Uma ubufakazi bukhomba ikliyenti eyodwa, hlola i-adaptha efihliwe esikhundleni sokufaka kabusha isitaki. Umyalo wokuqala ubala izixhumanisi ze-WAN Miniport namagama azo; owesibili uthatha igama eliyibuyisile, hhayi igama elikopishwe encwadini yokuhola.
Get-NetAdapterBinding -Name "<name>" -IncludeHidden -AllBindingsFunda uhlu ukuze uthole ukuxhumeka kokuxazulula amakheli kanye nezihlungi zezinhlangano zangaphandle. Ukuxhumeka okuvaliwe ukulungisa okuqondisiwe, kuyilapho ukuba khona kwesihlungi kuwumbuzo kumnikazi waleyo software hhayi imvume yokuvala umkhiqizo wokuphepha. Ukususa wonke ama-adaptha yisona senzo esisodwa esichitha ubufakazi obuzowudinga uma ukwehluleka kubuya.
Ngemva kokulungiswa, zama iphrofayili efanayo futhi bese uphinda icala lamakliyenti amabili uma kwakuyisibonakaliso sokuqala, ngoba ukuxhumana kokuqala okuphumelelayo kufihla inkinga yokwaba eveza ikliyenti lesibili. Gcina inothi ezingxenyeni ezine: yiliphi ikliyenti, ukuphi ukuxhumeka, wuphi umcimbi nokuthi kwashintsha ini. Shintsha isendlalelo esisodwa ngomzamo ngamunye futhi, ngoba ukulungiswa kwekliyenti nokushintshwa kweqoqo okusetshenziswe ndawonye akukwazi ukubalwa, futhi ukwehluleka okulandelayo kuzobonakala kukusha noma kuyikho.
