Zikuwoneka kuti iPhone yanga idayiwala mawu achinsinsi pa intaneti ya Wi-Fi

Hello aliyense!

Sindinaganizepo kuti ndibwereranso pamlanduwu, koma Cisco Open Air Wireless Marathon zinandipangitsa kukumbukira ndi kulankhula za zomwe ndinakumana nazo, pamene pang'ono kupitirira chaka chapitacho ndinali ndi mwayi kuthera nthawi ndithu kuphunzira vuto ndi Cisco ofotokoza opanda zingwe maukonde ndi mafoni iPhone. Ndidapatsidwa ntchito yoyang'ana funso la m'modzi mwa oyang'anira: "Bwanji, mutayambiranso, iPhone siyingalumikizane ndi netiweki ya Wi-Fi, ndipo mukalumikiza pamanja, imakufunsani kuti mulowetse dzina lanu lolowera ndi mawu achinsinsi?"

Zambiri pa netiweki ya Wi-Fi:

Wowongolera opanda zingwe - AIR-CT5508-K9.
Mtundu wa pulogalamu ya Controller ndi 8.5.120.0.
Malo ofikira - makamaka AIR-AP3802I-R-K9.
Njira yotsimikizira ndi 802.1x.
Seva ya RADIUS - ISE.
Makasitomala ovuta - iPhone 6.
Mtundu wa pulogalamu ya kasitomala ndi 12.3.1.
pafupipafupi 2,4 GHz ndi 5 GHz.

Kupeza vuto pa kasitomala

Poyamba, panali kuyesa kuthetsa vutoli mwa kuukira kasitomala. Mwamwayi, ndinali ndi mtundu wa foni womwewo monga wofunsira ndipo ndimatha kuyesa pa nthawi yoyenera kwa ine. Ndinayang'ana vuto pa foni yanga - ndithudi, nditangoyatsa foni ndikuyesa kulumikiza ku intaneti yomwe imadziwika kale, koma pambuyo pa masekondi a 10 imakhalabe yosagwirizana. Mukasankha SSID pamanja, foni imakufunsani kuti muyike malowedwe anu ndi mawu achinsinsi. Mukalowa nawo, zonse zimagwira ntchito bwino, koma mutayambiranso foni simungagwirizanenso ndi SSID, ngakhale kuti malowedwe ndi mawu achinsinsi adasungidwa, SSID inali mndandanda wa maukonde odziwika, ndipo kugwirizana kwa galimoto kumayatsidwa.

Kuyesera kosatheka kunapangidwa kuiwala SSID ndikuyiwonjezeranso, kukonzanso zosintha zapaintaneti ya foni, kusintha foni kudzera pa iTunes, komanso kusinthira ku mtundu wa beta wa iOS 12.4 (waposachedwa kwambiri panthawiyo). Koma zonsezi sizinathandize. Zitsanzo za anzathu, iPhone 7 ndi iPhone X, zidafufuzidwanso, ndipo vutoli lidapangidwanso pa iwo. Koma pa mafoni a Android vuto silinathe. Kuphatikiza apo, tikiti idapangidwa mu Apple Feedback Assistant, koma mpaka pano palibe yankho lomwe lalandiridwa.

Kuthana ndi zovuta zowongolera opanda zingwe

Pambuyo pa zonse pamwamba, anaganiza kuyang'ana vuto mu WLC. Nthawi yomweyo, ndinatsegula tikiti ndi Cisco TAC. Kutengera malingaliro a TAC, ndidasintha chowongolera kukhala mtundu 8.5.140.0. Ndidasewera ndi ma timer osiyanasiyana komanso Fast Transition. sizinathandize.

Poyesa, ndidapanga SSID yatsopano yokhala ndi kutsimikizika kwa 802.1x. Ndipo apa pali kupotoza: vuto silimaberekanso pa SSID yatsopano. Funso la injiniya wa TAC limatipangitsa kudabwa zomwe tidasintha pa netiweki ya Wi-Fi vuto lisanawonekere. Ndikuyamba kukumbukira ... Ndipo pali chidziwitso chimodzi - SSID yomwe inali yovuta kwa nthawi yaitali inali ndi njira yotsimikizirika ya WPA2-PSK, koma kuti tiwonjezere chitetezo tidasintha kukhala 802.1x ndi kutsimikiziridwa kwa domain.

Ndimayang'ana chidziwitso - ndikusintha njira yotsimikizira pamayeso a SSID kuchokera ku 802.1x kupita ku WPA2-PSK, ndikubwerera. Vuto silingathe kubwezeredwa.

Muyenera kuganiza mozama - ndimapanga SSID yoyeserera ndi WPA2-PSK kutsimikizika, kulumikiza foniyo, ndikukumbukira SSID mufoni. Ndimasintha kutsimikizika kukhala 802.1x, kutsimikizira foniyo ndi akaunti ya domain, ndikuyambitsa kulumikizidwa kwadzidzidzi.

Ndikuyambiranso foni ... Ndipo inde! Vutolo linabwereza lokha. Iwo. Choyambitsa chachikulu ndikusintha njira yotsimikizira pa foni yodziwika kuchokera ku WPA2-PSK kupita ku 802.1x. Ndinanena izi kwa injiniya wa Cisco TAC. Pamodzi ndi iye, ife kuberekanso vuto kangapo, anatenga dambo magalimoto, mmene zinali zoonekeratu kuti pambuyo kuyatsa foni, akuyamba kutsimikizika gawo (Access-Challenge), koma patapita kanthawi amatumiza uthenga diassociation kwa malo olowera ndikuchotsapo. Iyi ndi nkhani ya mbali ya kasitomala.

Ndipo kachiwiri pa kasitomala

Popanda mgwirizano wothandizira ndi Apple, panali kuyesa kwautali koma kopambana kufika pamzere wawo wachiwiri wothandizira, momwe ndinafotokozera vutoli. Ndiye panali zoyesayesa zambiri zodziyimira pawokha kuti apeze ndikuzindikira chomwe chimayambitsa vutoli pafoni ndipo zidapezeka. Vuto lidapezeka kuti ndi ntchito yolumikizidwa "iCloud keychain". Ntchito yothandiza kwambiri, yomwe wodandaula wa vutoli ndi ine sitinkafuna kuletsa pa mafoni ogwira ntchito. Malinga ndi lingaliro langa, foni siingathe kulemba zambiri zokhudza njira yolumikizira ma SSID odziwika pa ma seva a iCloud. Zomwe ndinapeza zinanenedwa. ku Apple, komwe adavomereza kuti pali vuto lotere, limadziwika kwa opanga, ndipo lidzakonzedwa m'mabuku amtsogolo.Sananene kuti ndi kumasulidwa. , koma koyambirira kwa Disembala 2019, vutolo linali likupezekabe pa iPhone 11 Pro Max yokhala ndi iOS 13.

Pomaliza

Kwa kampani yathu vutoli linathetsedwa bwino. Chifukwa chakuti dzina la kampani linasinthidwa, adaganiza zosintha SSID yamakampani. Ndipo SSID yatsopano idapangidwa kale nthawi yomweyo ndi kutsimikizika kwa 802.1x, zomwe sizinali zoyambitsa vutoli.
