Ifoni endala njengegesi ye-VPN: izimo ezintathu okufanele zihlolwe
Ifoni endala iyithuluzi kuphela uma indima isekelwa, inethiwekhi ingayifinyelela futhi othile ubhekele ukubuyiswa. Izimo ezintathu, isinqumo esisodwa.
Ifoni esekhabetheni ineprosesa, isitoreji se-flash, i-Wi-Fi nebhethri, okuwuhadiwe oluningi kuneziningi zekhompyutha zebhodi elilodwa abantu abazifaka ngokuzimisela. Inesikrini, ibhethri eligugayo kanye nohlelo lokusebenza oluyeka ukuthola izichibiyelo lapho umthengisi eqhubekela phambili. Akukho kulokhu okunquma ukuthi kufanele ibe igesi ye-VPN noma i-NAS.
Ukuthi kufanele ibe igesi ye-VPN noma i-NAS akunqunywa yilokho kuqhathanisa, ngoba ukuqhathanisa kumayelana namandla futhi isinqumo simayelana nokusebenza.
Izimo ezintathu ziyanquma. Uma esisodwa sihluleka, iphrojekthi iwukuzama kwempelasonto hhayi ithuluzi, futhi kungcono ukwazi ukuthi yisiphi isimo esahluleka ngaphambi kokudlulisa idatha kuyo.
Isimo sokuqala: indima isekelwa ngempela
Izinhlelo ezintathu zibizwa ngegama elilodwa. Iklayenti ye-VPN ivikela ukuhamba kwama-app efonini. Iseva ye-VPN yamukela ukuxhumana okungenayo. Igesi idlulisela ukuhamba kwezinye izinto kumhubhe. Lezi ziphrojekthi ezihlukene, futhi umhubhe weklayenti osebenzayo awufakazi lutho ngezinye ezimbili.
Uhlelo lokusebenza ku-Android ejwayelekile lungaphansi kwemithetho yokusebenza ngemuva, futhi itheminali eshiywe ivuliwe akuyona i-daemon. Umhlahlandlela we-Doze ne-App Standby wale nsizakalo ngokwayo uchaza ukuthi kungani inqubo yangemuva ingalahlekelwa ukufinyelela kunethiwekhi lapho idivayisi inquma ukuhlala ingenzi lutho, futhi lokho kuyisimilo okungeke kube khona egesini.
Isikhala somsebenzisi se-Linux ngaphakathi kwe-Android sithola imikhawulo eminingi kunalokho esikukhiphayo. I-chroot ishintsha impande yohlelo lwamafayela kodwa isasebenza ku-kernel ye-Android, izishayeli zayo kanye nenqubomgomo yezokuphepha, ngakho i-root ngaphakathi kwe-chroot akuyona i-root phezu kwale nsizakalo. Ukushintsha uhlelo lokusebenza esikhundleni salokho kwenza ukusekelwa kwe-modem, isitoreji namandla kuleyo foni ethile kube yingxenye yephrojekthi yakho, futhi ukusekelwa kwefoni ngokuvamile kuyingxenye okungekho muntu oyinakekelayo.
Isimo sesibili: ikheli liyafinyeleleka
Igesi kumele lifinyeleleke kumaklayenti ancike kulo. Ifoni ekwi-Wi-Fi ngaphakathi kwerutha yasekhaya iyafinyeleleka kulelo LAN nakuyo yonke indawo irutha edlulisela kuyo, kodwa hhayi ku-inthanethi ngaphandle uma ukuhlela lokho.
Umsakazo weselula wenza lokhu kube nzima hhayi lula. Amanethiwekhi amaningi eselula abeka ababhalisile ngemuva kwe-NAT yezinga lomhlinzeki, ngakho akukho kheli elingenayo lokudlulisela kulo nhlobo, futhi ukwengeza i-modem akudali isilaleli somphakathi. Uma isidingo kuwukufinyelela kude kusuka ngaphandle, umklamo kumele uhlanganise i-relay noma inethiwekhi yokumboza lapho zombili izinhlangothi zixhuma khona ziphuma, futhi leyo ingxenye yesibili ehambayo okufanele inakekelwe.
Ukuxhumana kwenethiwekhi nakho kuyahluka ngedivayisi. Amanye amafoni amukela ama-adaptha e-Ethernet e-USB, amanye awamukeli, futhi i-Wi-Fi yengeza ukubambezeleka kwayo nokuziphatha kwayo kwe-roaming. Igesi elilala lapho isikrini sicishiwe noma elilahla umhubhe ngesikhathi sokudluliswa libi kakhulu kunokungabi khona kwegesi.
Isimo sesithathu: othile ubhekele izibuyekezo nokubuyiswa
Lesi yisimo abantu abasidlulayo, futhi yiso esinquma ukuthi into izophila unyaka yini. Ingxenye ngayinye idinga umnikazi: ukwakhiwa kohlelo lokusebenza, i-kernel uma uyishintshile, iphakethe leseva, izitifiketi kanye nobufakazi obuwusabalalisa.
Ukubuyiswa ingxenye enzima. Ungena kanjani ngemuva kokuqalisa kabusha ngaphandle kwesikrini, ngephaneli yokuthinta ephukile noma ibhethri elivuvukile? Uwukhanseka kanjani ubunikazi beklayenti obulahlekile? Ubuyisela kanjani isitoreji kudivayisi yokushintsha lapho eyokuqala iyimodeli eye yamiswa?
Amandla nawo ayingxenye yalokhu. Umthwalo oqhubekayo usho ukushisa okuqhubekayo, futhi ibhethri eligugayo aliyona i-UPS ezenzakalelayo. Landela isiqondiso somkhiqizi, futhi thwala noma yikuphi ukuvuvukala noma ukulimala njengophawu lokuma hhayi into okufanele igwenywe.
Lapho impendulo ingu-cha
Sebenzisa izimo ezintathu kulokho okudinga ngempela, futhi ube oqondile mayelana nomsebenzi hhayi isigaba.
| Task | Phone is reasonable when |
|---|---|
| Protecting the phone's own traffic | The client is a supported Android app; no forwarding involved |
| Small lab tunnel inside one LAN | Downtime is acceptable and you can reach the device to fix it |
| Household NAS holding the only copy | Never; that is a backup problem, not a hardware problem |
| Unattended remote access for others | You already own patching, revocation and replacement |
Isiphathi se-Linux esizinikele naso asiphunyuki ohlwini. Sinomphathi wensizakalo nendlela yokuphatha isitoreji nenethiwekhi ecacile lapho ihadiwe nokusabalalisa kusekelwa, kodwa sisadinga amandla, izibuyekezo nezipele. Ibhodi lodwa aliyona ithuluzi.
Ngakho khetha ifoni lapho amakhono ayo asekelwe efanele umsebenzi omncane futhi ukungasebenzi kokuhlola kwamukeleka ngempela. Khetha enye into lapho isidingo siyisitoreji sasekhaya esingafanele silahleke, noma ukufinyelela kude abanye abantu abazokuthembela. Kuzo zombili izimo isici esinqumayo ukufakwa okungaphindwa kanye nenqubo yokubuyiswa oyihlole ngempela, futhi asikho isamba sehadiwe yamahhala esingena esikhundleni salokho.
