Awudingi ukutholwa kwe-Bonjour ukuze uphrinte nge-VPN

Kungenzeka ukuthi watshelwa ukuthi ukuphrinta kusuka ku-iPhone nge-VPN kudinga ukuthi ukutholwa kwe-Bonjour kweqe umhubhe. Leyo nkolelo iqondisa abantu emabhulohweni e-TAP kanye nezidluliseli ze-multicast ezingalungisi lutho. I-AirPrint yamukela indawo eqondile: iphrofayela yokulungiselela inganika ifoni ikheli, indlela yomsiza kanye nechweba lephrinta. Ukutholwa akudingeki kwenzeke ukuze leyo ngxenye ivele kushidi lokuphrinta. Lokho i-payload engakwenzi ukudala indlela, ukwenza iphrinta engeyona i-AirPrint ikhulume i-IPP noma ukugunyaza umsebenzi.

Inganekwane iqala ngokubona okuyiqiniso

I-Bonjour iyi-multicast yasendaweni ngokomklamo wayo. Umhubhe oqondisiwe osuka endaweni ukuya endaweni awuzithwali lezo qembu, ngakho ifoni ekwi-VPN ayikwazi ukuphequlula amaphrinta aku-LAN ekude, futhi nekhompyutha ephathekayo emhubheni ofanayo ayikwazi. Isiphetho esilungile akukhona ukuthi ukuphrinta kudinga ibhuloho; ukuthi ukuphequlula kudinga enye indlela yokuletha, futhi uhlu olucacile yilona ndlela.

Izidluliseli ze-multicast zikhona futhi amanye amanethiwekhi aziphatha kahle, kodwa zixazulula isidingo sokutholwa okungenzeka ungenaso. Uma ukusetshenziswa kudinga ukuphrinta kuphela kudivayisi eyodwa egunyaziwe, ukushicilela leyo divayisi kuncane, kuyahlolwa futhi kulula kakhulu ukuyihoxisa kunokwandisa isizinda sokusakaza ngomhubhe.

Yini i-payload eyithwalayo ngempela

I-payload com.apple.airprint iqukethe uhlu lwezichazamazwi zamaphrinta. Isichazamazwi ngasinye sithatha i-IPAddress, okungaba ikheli elingokoqobo noma igama lomsingathi, i-ResourcePath, i-Port engakhethwa kanye ne-ForceTLS engakhethwa. I-Apple ibhala i-Port ne-ForceTLS kusukela ku-iOS 11, ngakho iqembu elixubile kufanele likucacise lokho ngaphambi kokusatshalaliswa.

Indlela iyinkambu abantu abayiqagelayo. I-ResourcePath ibonisa inani le-rp kurekhodi le-Bonjour lephrinta _ipps._tcp noma _ipp._tcp. Ivamise ukuba yi-ipp/print kumaphrinta esimanjemanje angenazo izishayeli futhi ivamise ukuba yinto eqondene nomkhiqizi kumadala. Ukukopisha indlela kusuka kumodeli ohlukile kudala ulayini ovelayo bese wenqaba wonke umsebenzi.

Into eyodwa ohlwini ibukeka kanje, namanani ezikhala angewona umkhawulo ohloliwe:

<dict>
    <key>ResourcePath</key>
    <string>ipp/print</string>
    <key>IPAddress</key>
    <string>printer-07.office.example</string>
    <key>Port</key>
    <integer>8631</integer>
    <key>ForceTLS</key>
    <true/>
</dict>

Leyo ngxenye akuyona iphrofayela. Ingenye into yohlu lwe-AirPrint ngaphakathi kwe-payload, futhi i-payload isadinga imethadatha yayo kanye nesiginesha noma ukulethwa kwe-MDM. Isichazamazwi sephrinta se-AirPrint siyincwadi yokubhekisa ezincazelweni zezinkambu.

Qoqa amanani kusuka kuphrinta, hhayi kumphumela wokusesha

Ku-Mac osekuvele uphrinta kudivayisi, i-ippfind noma i-dns-sd -B _ipp._tcp ibonisa isenzakalo esikhangisiwe, futhi isixhumi esibonakalayo sewebhu sephrinta ngokwayo sivamise ukubala indlela ye-IPP nechweba. Bhala wonke amanani amane kunothi lokusatshalaliswa ukuze umuntu olandelayo angaphindi awathole kusithombe-skrini.

Bese unquma nge-TLS ngamabomu. Uma i-ForceTLS iyiqiniso, ifoni kufanele ithembe isitifiketi esethulwa iphrinta, futhi isitifiketi esisayinwe ngokwaso siyahluleka ngaphandle uma nawe usabalalisa i-ankile yokuthemba. Ukucisha i-TLS ukuze ulayini usebenze isinqumo mayelana nendlela yenethiwekhi, hhayi indlela yokugwema isitifiketi esingesihle.

Ukulethwa, bese kuba ukuhluleka okubili okuphambene

Letha i-payload ngesiteshi sakho sokuphatha amadivayisi lapho sikhona, futhi thwala iphrofayela efakwe ngesandla efonini yomsebenzi njengokuhlukile okuyikho. Uma isifakiwe, iphrinta kufanele ivele kushidi lokuphrinta ngaphandle kwanoma yiziphi izithuthuthu zokutholwa. Lokho kuvela yikona kuphela i-payload eyayifanele ukuqinisekisa.

Iphrinta evelayo kodwa ehluleka kuwo wonke umsebenzi inenkinga yendlela, yechweba, yendlela noma ye-TLS, futhi akukho nanye yazo exazululwa i-payload.

Iphrinta engaveli neze inenkinga yokulethwa noma ye-payload esikhundleni salokho: iphrofayela ayifakwanga, uhlu lulimele, noma inani alihambisani nedivayisi. Funda kabusha amanani kanye nedivayisi eqondiwe ngaphambi kokuthinta i-VPN. Ukwengeza isidluliseli sokutholwa ukuze kulungiswe inkinga yohlu kuyiphutha elibizayo, ngoba uhlu alukaze lwancika ekutholweni.

Gcina ingxenye ikwazi ukunakekelwa

Khetha igama lomsingathi kunekheli elingokoqobo lapho ulawula khona isifunda, ukuze ukushintsha kwekheli kungonakalisi yonke iphrofayela efakiwe. Lelo gama lomsingathi kufanele lixazululwe kusuka efonini ngenkathi umhubhe uvuliwe, okulibuyisela engxoxweni ye-split-DNS hhayi eyokuphrinta.

Bhala umnikazi wephrinta kanye nomnikazi wephrofayela kurekhodi lokusatshalaliswa. Uma ulayini uhamba, buyekeza indawo eshicilelwe ngamabomu, ngoba ingxenye endala ayipheli ngokwayo futhi iqhubeka iqondisa abasebenzisi kudivayisi eseyekisiwe.

Akukho kulokhu okwenza iphrinta ikwazi i-AirPrint. I-payload ishicilela indawo, futhi idivayisi kusamele ikhulume i-IPP.
