Uhlelo lwe-VPN lomhlinzeki ngokumelene ne-NetworkManager: ubani ongumnikazi wesimo?
Iphrofayili ibiza ingxenye yokungeza, hhayi ukuziphatha kwekhasimende lomhlinzeki. Hlela ukuthi ubani ongumnikazi wokubhalisa, i-DNS, ukuvimba kanye nezibuyekezo ngaphambi kokushintsha ikhompuyutha ephathwayo.
Ukungenisa iphrofayili akufani nokushintsha ikhasimende. I-NetworkManager igcina uhlobo lwengxenye yokungeza kanye nedatha nezimfihlo eziqondene nengxenye yokungeza, futhi ingxenye yokungeza engumnikazi walolo hlobo iyona enquma ukuthi uxhumano lungenzani. Konke okubekwa uhlelo lomhlinzeki phezulu, kusukela ekubhaliseni kuze kube ukuvimba okungapheli, kuhlala ngaphandle kwefayela. Ukuthi ushintsho luphephile yini kuncike ekutheni yiziphi kulezi zendlalelo ozethemba ngazo ngempela.
Ifayela libiza ingxenye yokungeza, hhayi iqoqo lezici
I- referensi yezilungiselelo ze-VPN ku-NetworkManager ichaza uhlobo lwensizakalo olukhetha ingxenye yokungeza, kanye nesichazamazwi sedatha esingacacile nesichazamazwi sezimfihlo okunguyo kuphela engxenye yokungeza esihumushayo. Iphrofayili iyisivumelwano nokwakhiwa okukodwa, hhayi incazelo yokuziphatha okungabuyiselwa yinoma yiliphi ikhasimende. Amakhasimende amabili angakhuluma iphrothokholi efanayo futhi ahluke ngokuthi axoxisana ngani nokuthi iyiphi imigudu yedatha ayivulayo. Igama lephrothokholi likutshela ukuthi umhubhe uyini, alikutsheli neze ukuthi ikhasimende elizungezile lenzani ngawo.
Ngakho-ke qhathanisa izinto ezidingekayo, hhayi izembozo. Umbuzo awukho ekutheni ukunye okunye kungaxhuma yini, ngoba ngokuvamile kuyaxhuma; umbuzo ukuthi isidingo ngasinye esenza ikhasimende lokuqala lamukeleka siyasinda yini ekuthutheni. Bhala lezo zidingo ngaphambi kokufaka noma yini, kungenjalo ukuqhathanisa kuphenduka ukufuna okuzoqala ukwephuka.
Yini engezwa uhlelo lomhlinzeki ezungeze umhubhe
Amakhasimende omhlinzeki ngokuvamile ahlanganisa ukubhalisa nokuhlola isimo sedivayisi, ukugeleza kwesici sesibili okunengxenye yayo yokuxhumana, ukuvimba okungapheli, isiteshi sezibuyekezo kanye namathuluzi okusekela. Okunye kwalokho kuma eduze kwephrothokholi, kanti okunye kuwumkhiqizo ohlukile owabelana kuphela ngesifaki. I-NetworkManager ingashintsha umhubhe nokuhamba kwawo, futhi imibhalo yokuthumela ingaqalisa izenzo lapho isimo soxhumano sishintsha. Kodwa ayikubuyiseli injini yokuvimba, inqubo yokuvuselela isitifiketi noma umcabango wokuthi yimuphi umsebenzisi ovunyelwe ukuphakamisa uxhumano.
Izingxenye eziningi azisho ukuthi kuphephe kakhulu, futhi ezimbalwa azisho ukuthi kubuthaka kakhulu. Umbuzo ukuthi iyiphi ingxenye eqinisekisa inqubomgomo okwathiwa uyilandele. Uma umhloli ebuza ukuthi yini evimbayo ithrafikhi lapho umhubhe uwa, impendulo kufanele ibize into eyenza lokho ngempela, futhi iphrofayili exhuma kuphela ayiyona leyo mpendulo.
Lapho ubunikazi buhluka khona ngempela
Funda lokhu njengebalazwe lobunikazi hhayi njengohlu lokuhlola, ngoba ukwehluleka okungezansi yizikhala zobunikazi futhi akukho nobuningi bokumiswa kwekhasimende okuzivalayo. Umugqa ngamunye ubiza indlalelo, uhlangothi oluvamise ukuyibamba namuhla, nendawo okubonakala kuyo kuqala isikhala.
| Layer | Vendor application | NetworkManager connection | Where the gap shows up |
|---|---|---|---|
| Enrollment and posture | built into the client | absent unless something else supplies it | a managed device fails its next posture check |
| Address and resolver authority | the client sets both | the plugin plus dispatcher scripts | names resolve through the wrong resolver after a state change |
| Blocking on drop | a bundled engine | nothing by default | traffic continues in the clear after the tunnel dies |
| Upgrade path | the vendor's own channel | the distribution package and its plugin | a plugin update changes behaviour with no vendor note |
| Diagnostics and support | vendor tooling with client state | journal and dispatcher output | support cannot see why negotiation failed |
Hlanganisa umugqa ngamunye nokubona ongakwazi ukuphinda, hhayi umuzwa ngekhasimende. Igama elixazululwe ngesixazululi esihlosiwe, umzila onyamalalayo lapho umhubhe uma, kanye noxhumano oluvinjiwe ngemuva kokuphazamiseka okufanisiwe — lokhu kubona okuthathu kuhlangene kuhlanganisa ingxenye enkulu yethebula. Bhala okubona eduze kwesidingo esikufakazelayo, futhi gcina lokho okwehlulekile, ngoba okubona okwehlulekile yikho kuphela okuyingxenye yerekhodi ebikezela isigameko esilandelayo.
Ukushintsha ngaphandle kokugqagqana kobunikazi
Ukuqalisa ikhasimende lomhlinzeki kanye noxhumano lwe-NetworkManager lwensizakalo efanayo ngasikhathi sinye iyona ndlela evamile yokuthi lokhu kuqhathanisa kungahambi kahle. Kokubili kufaka imigudu, kokubili kungabeka i-DNS, futhi kokubili kungathinta isimo somthombo womlilo. Lokho okukukalayo ngaleso sikhathi ukuhlelwa kwesithathu okungahambisani nokuziphatha okubhaliwe kwamakhasimende womabili.
nmcli -f NAME,UUID,TYPE connection show
nmcli connection show work --show-secrets | grep -E "^vpn\."
journalctl -u NetworkManager -b --since "10 min ago"Umyalo wokuqala ukutshela ukuthi iphrofayili iwuhlobo lwe-VPN noma cha. Owesibili ukhombisa uhlobo lwensizakalo yengxenye yokungeza nokuthi iziphi izimfihlo ezigciniwe, okubalulekile lapho ukhiye ulindeleke kumenzeli hhayi efayeleni. Ijenali iyindawo okuzothi ingxenye yokungeza elayishiwe kodwa engakwazanga ukuxoxisana isho lokho khona. Uma okukodwa kokuthathu kungabonisi inkinga, isikhala sisezendlalelo zenqubomgomo ezingaphezu komhubhe hhayi ekuxhumaneni.
Nqamula ikhasimende elidala ngaphambi kokuvula uxhumano olusha, gcina iziphetho zomugqa kanye ne-akhawunti kufana, bese ubhala ukuthi iyiphi ingxenye engumnikazi wemigudu, izilungiselelo zesixazululi nokuvimba. Leyo nothi iyona evimbela isibuyekezo esilandelayo ukuthi siphele ngabanikazi ababili.
