27850, 442 iyo 651: hal stack, saddex hubin oo ugu horreeya
Saddexda khalad waxay ka yimaadaan stack-ka adapter-ka macmalka ah. Ku habee lambarka lakabkiisa, hubi lakabkaas, oo dib u rakib kaliya ka dib nadiifinta.
Barnaamijka rakibidda wuxuu joogsadaa 27850, xiriirku wuu diidayaa 442, iyo profile kale wuxuu soo celiyaa 651. Lambarrada waxay u eg yihiin saddex cilad oo kala duwan, jawaabta caadiga ahna waa in client-ka saddex jeer dib loo rakibo. Laakiin waxay ka yimaadaan hal nidaam hoose: adapter-ka macmalka ah iyo stack-ka filter-ka ee hareerihiisa. Lambarka khaladku wuxuu sheegaa lakabka fashilmay, taasna waxay go’aamisaa hubinta koowaad. Dib u rakibidda ka hor inta aan lambarka la akhrin badanaa waxay soo saartaa isla ciladii.
Ku habee lambarka lakabka
Khalad kastaa wuxuu ka soo baxaa meel ka duwan, sidaas darteed hubinta koowaad way duwan tahay xitaa marka calaamadda muuqata ay tahay isla xiriirkii la diiday. Saddex qoys ayaa daboolaya dhammaan kiisaska: barnaamijka rakibidda, adapter-ka iyo port-ka hoostiisa. Shaxda hoose waxay lambar kasta dhigtaa dhinaca hubinta loo baahan yahay.
| Error | When it appears | First check | Usual cause |
|---|---|---|---|
| 27850 | During install | Filter count and security suite | Stack at the filter limit, or a suite blocking the driver |
| 442 | On connect | Adapter state and display name | Disabled adapter, ICS holding it, malformed CVirtA name |
| 651 | On connect | WAN miniport and third-party drivers | Miniport failed to start, bridging driver attached |
Haddii khaladku soo baxo ka hor inta aan profile la dooran, wuxuu ka tirsan yahay qoyska rakibidda. Haddii uu soo baxo marka client-ku isku dayo inuu adapter-ka kor u qaado, wuxuu ka tirsan yahay qoyska adapter-ka. Haddii adapter-ku muuqdo laakiin port-ku waligiis aan furnaan, waa qoyska miniport. Qor lambarka ka hor inta aanad wax beddelin. Saddexda hagaajin waxay taabanayaan qaybo kala duwan oo stack-ka ah, beddelka qoys khaldan loo sameeyayna wuxuu isku dayga xiga ka dhigaa mid adag in la akhriyo.
Stack filter oo buuxa, ama xirmo ammaan oo xannibaya driver-ka
Rakibidda client-ku waxay diiwaangelisaa qayb yar oo filter ah silsiladda adapter-ka. Windows waxay leedahay xad adag oo ku saabsan inta qaybood ee noocaas ah la xiri karo, qiimaha caadiga ahna wuxuu ka taga qayb yar marka antivirus, buundada virtualisation iyo driver qabashada ay joogaan. Markaas rakibidda waxay ku fashilantaa 27850 inkasta oo xirmada VPN ay fiican tahay. Barnaamijka rakibidda ma kala saari karo stack buuxa iyo mid jaban.
Akhri qiimaha hadda, kordhi, oo dib u bilow ka hor inta aanad mar kale isku dayin. Filter cusub ma xiri karo ilaa stack-ka dib loo dhiso:
reg query "HKLM\SYSTEM\CurrentControlSet\Control\Network" /v MaxNumFilters
reg add "HKLM\SYSTEM\CurrentControlSet\Control\Network" /v MaxNumFilters /t REG_DWORD /d 14 /fSababta kale waa xirmo ammaan oo xannibaysa rakibidda driver-ka iyada oo aan digniin muuqata jirin. Ilaalinteeda ku timid waxay hor istaagi kartaa diiwaangelinta filter-ka, sidaas darteed barnaamijka rakibidda wuxuu soo sheegaa guuldarro qayb guud. Eeg log-ga xirmada lafteeda, haddii ilaalinta ku timid ay tahay caqabadda, dami kaliya inta lagu jiro rakibidda oo isla markiiba dib u shid. Haddii qiimaha horey loo kordhiyay oo aan xirmo xannibin, raadi driver-yada filter ee hadhay ee ka yimid badeeco VPN hore. Filter duug ah oo aan lahayn adeeg u dhigma wali wuxuu qabsadaa boos wuxuuna fashilmi karaa rakibidda cusub.
Adapter-ku wuu jiraa oo hoos ayuu ku sii jiraa
Khaladka 442 waxay la macna ah in adapter-ka macmalka ah uu jiro laakiin client-ku uusan kor u qaadi karin. Hubinta koowaad waa Maamulaha Qalabka oo muujinaya qalabka qarsoon: adapter la damiyay, adapter leh calaamad digniin iyo adapter maqan dhamaantood waxay u muuqdaan isku mid client-ka laakiin waxay u baahan yihiin hagaajin kala duwan. Internet Connection Sharing ayaa badanaa hayaa. Haddii adeeggu qabsaday adapter-ka, jooji adeegga oo mar kale isku day ka hor inta aanad taaban diiwaanka. Habaynta wadaagga hadhay waxay mar kale qabsan kartaa ka dib dib u bilow, sidaas darteed qor haddii hagaajintu ay sii socoto dib u bilowga kadib.
Dib u rakibidda waxay ka tagi kartaa magac bandhig oo qaldan oo adapter-ka ka dhigaya mid aan la maamuli karin. Qiimuhu waa inuu ahaadaa qoraal cad, ma aha token rakibid oo aan la xallin:
Get-ItemProperty "HKLM:\SYSTEM\CurrentControlSet\Services\CVirtA" -Name DisplayName
Set-ItemProperty "HKLM:\SYSTEM\CurrentControlSet\Services\CVirtA" -Name DisplayName -Value "Cisco Systems VPN Adapter for 64-bit Windows"Isticmaal magaca bandhig ee client-kaagu filayo, kadibna dib u bilow si adapter-ka dib loo tirin. Dejinta qiimaha iyada oo aan dib loo bilowin badanaa waxay ka tagtaa xaaladdii hore, xiriirka xigana wuxuu mar kale bixiyaa 442.
Port-ka hoostiisa waligiis ma furno
Khaladka 651 waxaa la soo sheegaa marka maamulaha xiriirka uusan furi karin miniport-ka WAN. Adapter-ku wuxuu u muuqan karaa mid caafimaad qaba client-ka halka port-ka hoostiisa uusan waligiis gaarin xaalad bilaaban. Liis miniport-yada iyo xaaladdooda ka hor inta aanad wax dib u rakibin:
Get-PnpDevice -Class Net | Where-Object { $_.FriendlyName -like "*WAN Miniport*" } | Select-Object Status, FriendlyNameMiniport leh xaalad khalad waa tilmaanta tooska ah. Dib u rakibidda Maamulaha Qalabka waxay mar kale abuurtaa port-ka, taasna waa sababta hagaajintani u shaqeyso marka dib u rakibidda client-ku aanay shaqeyn. Driver-yada dhinac saddexaad ee ku xiran adapter-ka jireed waa sababta kale ee caadiga ah. Driver-ka shabakadda buundada VirtualBox, driver-ka TAP ee hadhay ee ka yimid OpenVPN ama filter qabasho ayaa laga yaabaa inay marka hore qabsadaan port-ka. Ka saaridda calaamadda qaybta inta lagu jiro rakibidda kuma filna marka driver-ku horey u xiran yahay; waa in laga saaro sifooyinka adapter-ka ama laga saaro bakhaarka driver-ka.
Daminta IPv6 ee xiriirka VPN waxay xallisey khaladkan build-yada qaar, laakiin u qaado tijaabo ee ma aha naqshad joogto ah. Haddii xiriirku ku bilaabmo kaliya marka IPv6 la damiyay, miniport-ka ama driver-ka hoose ayaa wali ah sababta.
Beddel hal lakab oo kaydi caddaynta
Kaydi qiimaha diiwaanka ee aad beddesho, qor liiska adapter-yada iyo filter-yada ka hor iyo ka dib, oo dib u bilow inta u dhaxaysa isku dayada. Dib u bilowgu waa qayb ka mid ah hagaajinta qoys kasta halkan, sababtoo ah stack-ka adapter-ka waxaa la dhisaa marka la bilaabayo oo dib u bilaabista adeeggu ma dib u dhiso.
Dib u rakib client-ka kaliya marka adapter-kii hore, filter-yadii iyo miniport-yadii ay tageen. Rakibidda client cusub oo dul saaran stack jaban waa dariiqa 27850 hagaajin karo uu u noqdo mishiin leh laba adapter oo nus-diiwaangashan iyo khalad cad oo maqan. Joogso oo kor u sheeg haddii isla khaladkaas uu laba jeer ka gudbo hubinta lakabka gaarka ah. Waqtigaas tallaabada xigta ee faa’iido leh waa dib u eegis nadiif ah oo stack-ka shabakadda ah oo la socda log-ga rakibidda ee iibiyaha, ma aha isku day kale oo isla dib u rakibiddaas ah.
