Uhlukanisa ukwehluleka kokuqalisa kwe-Pi engenawo isikrini nokwehluleka kwenethiwekhi

Ikhadi liyaphuma kusikhwama ngaphambi kokuba othile abuze ukuthi iyiphi yezinto ezine ehlulekile ngempela. I-Pi yayeka ukuphendula ngemva koshintsho lwe-VPN noma lwenethiwekhi, futhi uku-flasha kabusha kubonakala njengenyathelo okuwukuphela kwalo elisele. Akujwayelekile ukuba kube njalo: isivumelwano sokuqashwa singahamba, i-sshd ingama, noma impendulo ingaphuma ngendlela ongakwazi ukuyilandela, futhi ngakunye kwalokho kunekhambi lako. Umsebenzi owusizo ukuhlukanisa lokho okukubonile nalokho okucabangile.

Imiphumela emine, hhayi eyodwa

Ukuqalisa, ikheli, ukulalela nokufinyeleleka kuyimiphumela emine ehlukene, futhi noma iyiphi yayo ingahluleka ngenkathi ezinye zisamile. Ibhodi lingaqala ngokuphelele futhi lingaveli neze kunethiwekhi. Lingavela ngekheli obekungelindelekile muntu, noma ligcine ikheli elifanele ngenkathi i-SSH icishiwe. Lingenza kokuthathu ngendlela efanele futhi lingafinyeleleki ngoba izimpendulo ziphuma ngesango elingalungile.

Isifiso soku-flasha kabusha sihlanganisa lezo zine zibe umbuzo owodwa, yingakho sivame ukunikeza i-Pi esebenzayo kodwa singanikezi incazelo yokuthi yini eyaphuka ngempela.

Lapho ubufakazi buphela khona ngempela

Bhala izinto ezintathu ngaphambi kokuthinta noma yini: ikheli nokuxhumana okuphezulu okwakusebenza ekugcineni, okwashintshwa, nomsebenzi wokuqala owahoxa ukusebenza. Igama lomsingathi elingasaxazululwa, uxhumano lwe-SSH oluphelelwa yisikhathi, noxhumano lwe-TCP olwenqatshwayo kuyimibono emithathu ehlukene ekhomba izendlalelo ezintathu ehlukene. I-ping ehlulekile ihlola ukufinyeleleka kwekheli elilodwa futhi yehluleka ngazo zonke izizathu ezingenhla, kuhlanganise nebhodi elingakaze liqale. Ngakho ke ayikwazi ukuthatha indawo yokuhlolwa kokuqalisa.

Uma kukhona isibonisi sasendaweni noma ikhonsoli yokubuyisela, sebenzisa yona, ngoba umbuzo ewuphendulayo ukuthi umshini uyafinyelela yini kuhlelo lwayo lokusebenza. Lowo umbuzo okuwukuphela kwawo ongaxazululwa uku-flasha kabusha. Uma ibhodi lihluleka ngaphambi kwaleso sigaba, landela imibhalo yokubuyisela yeplathifomu esikhundleni sokucabanga ngokulimala kwehardware kusukela kusithombe-skrini esingekho, futhi uyeke ukudonsa ugesi njengendlela yokuxilonga.

Phinda wakhe indlela yokufinyelela ohlelweni olusebenzayo

Thola ukuxhumana okuphezulu nekheli lamanje ngalowo onokulungiselelwa kwenethiwekhi, bese uqhathanisa nalolo nohlu lwamaklayenti lwamanje lwerutha kanye nekheli elisetshenziswe yiklayenti le-SSH. Igama lomsingathi eligciniwe noma isivumelwano se-DHCP esidala kungakhomba endaweni yayizolo amasonto amaningi. Bese uqinisekisa ukuthi i-sshd ivuliwe, ilalela ekhelini elikhona, futhi ivunyelwe ukusuka kunethiwekhi yokuphatha. Umhlahlandlela we-SSH we-Raspberry Pi ubheka ukuvula iseva nokuxhuma ekhelini lamanje njengezinyathelo ezimbili ezihlukene, futhi ukufakwa okusha kwe-Raspberry Pi OS kushiya i-SSH ivaliwe ngokuzenzakalela.

Igama lomsingathi lingaphinde liqondiswe komunye umshini, futhi isithombe esikhundla siza nokhiye waso, ngakho hlola umnyezi womunwe ngendlela ose uyithembile esikhundleni sokuchofoza udlule isexwayiso. Ukususa isexwayiso yiyo indlela ushintsho lwekheli lwesikhashana oluba inkinga yokuthembana unomphela. Uma umbuzo wokhiye uwuphawu kuphela, ubheka udaba lobuwena hhayi ukufinyeleleka.

Landela indlela yempendulo ngaphambi kokusola ibhodi

I-VPN ingashintsha ukukhethwa kwendlela ngenkathi isixhumanisi somzimba sisaxhunyiwe, futhi yilowo kanye isimo lapho i-Pi ivuliwe, ilalela kodwa ingafinyeleleki. Isicelo siyafika futhi impendulo iphuma ngomhubhe iklayenti lomlawuli elingakwazi ukuwela. Ikhonsoli yasendaweni nesokhethi elalelayo akufakazi lutho ngendlela yokubuya, ngakho qinisekisa ukuthi yisiphi isixhumanisi esithwala impendulo nokuthi isiphi isango esikhethayo. Qhathanisa nalokho kunethiwekhi umlawuli akulo ngempela, ngoba lokhu kwehluleka kuxilongwa ngokungalungile njengebhodi elifile kaningi kunanoma yikuphi okunye.

Ukuhlola okushibhe kakhulu ukubuka impendulo iphuma: ku-Pi, buza ukuthi iyiphi indlela eyayizothwala ikheli lomlawuli bese uqhathanisa nesixhumanisi isicelo esafika kuso. Ukungafani lapho kuchaza uphawu lonke futhi kubiza umyalo owodwa.

Umngcele owodwa ngesikhathi, nokuthi uku-flasha kabusha kulungile nini

Lungisa ukulungiselelwa ngomnini kwayo ngemva kokugcina isimo samanje. Ukushintsha umphathi wenethiwekhi, ukukhipha i-firewall nokuqagela ikheli elingaguquki kuyizinto ezintathu ezenza umbono olandelayo ungabi nausizo. Uma ubufakazi bukhomba indlela ye-VPN noma ukuhlunga kwayo, buyela emuva enqubweni yayo yokumisa noma yokulungisa yaleyo klayenti, usebenza ngaphakathi kohlelo lokubuyisela okuvunyelwene ngalo; ukuqhathanisa okulawulwayo kwehlukile ekucisheni ukuvikelwa kumsingathi ongakuchazanga.

Uku-flasha kabusha isinqumo sokubuyisela esenziwe ngamabomu, esithathwa lapho usuqonda idatha, ubuwena nesigaba esihlulekile. Akusiyo into okufanele ukungena ngemvume okungekho kuyiqalise ngokuzenzakalela.

Gcina irekhodi lokulungiselelwa endaweni efundekayo ngaphandle kwe-Pi, nendlela yokubuyela ngaphakathi engadluli emhubheni ozowushintsha. Bese usebenza ngokulandelana: qinisekisa isigaba kusukela kukhonsoli yasendaweni, thola ikheli lamanje, hlola isilaleli nomgomo waso, landela indlela yempendulo, futhi ushintshe into eyodwa. Uma ibhodi lingakaze lifinyelele kuhlelo lokusebenza, isinyathelo esilandelayo imibhalo yokubuyisela hhayi inethiwekhi.
