Qhov zoo tshaj plaws: koj tuaj yeem siv nws yog, lossis thaum twg, Is Taws Nem poob qis (lossis yog tias koj nyob hauv qhov chaw deb & xav tau nkag mus rau Wikipedia). Huag hav, thiab yog tias koj tus phooj ywg tau txais ib qho thiab lawv nyob ze (*ahem*80ft*ahem*), koj tuaj yeem faib cov khoom nrog lawv thiab ua koj tus kheej txoj kab sib tham!

Qhov ntawd ua rau kuv xav.. yog tias cov neeg txaus tsim Pi Cloud servers, peb tuaj yeem ua neeg coob coob hauv Is Taws Nem! Qhov ntawd yuav yog 11/10 ntawm qhov ntsuas ntawm qhov zoo. Nrog cov qauv tshiab ntawm Raspberry Pi lub khoos phis tawj, nws ua tau thiab tsis kim li! (Dab tsi! Qhia kuv ntxiv!)

Phau ntawv qhia no yuav qhia koj yuav teeb tsa luv-ntau (~ 80 ft) WiFi Access Point thiab tus kheej lub vev xaib ('coj nws rov mus rau HTML bbies). Koj tuaj yeem teeb tsa qhov no ua (kaw) lub network hauv zos nkaus xwb (piv txwv li koj tus kheej "huab" cov cuab yeej thaub qab), lossis tshaj tawm nws mus rau lwm lub ntiaj teb! (.. yog tias koj ua qhov no nco ntsoov tias koj paub kev ruaj ntseg network.)

Qhov ntawd tau hais tias, piv txwv tias koj muaj kev paub yooj yim ntawm Pi, ntawm no yog qhov tawg:

Kauj Ruam 8: Hloov kho DHCP Configuration File

Cia peb teeb tsa DHCP cov txheej txheem kev sib txuas lus yog li peb tuaj yeem xa thiab tau txais cov ntaub ntawv (tseem ceeb heev yog tias koj xav tsim lub network txuas nrog)! Mus rau DHCP cov ntaub ntawv teeb tsa los ntawm kev ntaus cov hauv qab no:

sudo nano /etc/dhcp/dhcpd.conf

1. Ntxiv cov lus pom ("#") ua ntej ntawm kab hauv qab no (yog li nws zoo li cov ntawv hauv Duab 1):

xaiv sau npe-npe “example.org”;

xaiv sau npe-npe-servers ns1.example.org, ns2.example.org;

2. Tshem tawm cov lus pom ("#" ') los ntawm kab "muaj ntawv pov thawj" (Daim duab 1 kuj tseem pab tau ntawm no):

#Yog tias DHCP server no yog lub DHCP server rau lub network hauv zej zog, cov lus pom zoo tso cai yuav tsum tsis suav nrog.

#tso cai;

3. Ntxiv cov cai no mus rau qhov kawg ntawm cov ntawv (saib daim duab 2):

subnet 192.168.42.0 netmask 255.255.255.0 {

Qhov no ua dab tsi?! Txhawm rau (piav qhia luv luv), nws teeb tsa ntau qhov IP chaw nyob los muab rau cov khoom siv sib txuas (los ntawm 192.168.42.10 txog 192.168.42.50), ib yam li koj lub tsev router! Nws tseem qhia Pi li cas sib txuas lus rau lwm yam khoom siv (nws qhov chaw nyob tshaj tawm, 192.168.42.255, thiab nws tus kheej tus IP chaw nyob, 192.168.42.1). Nws muab sijhawm ntau (hauv vib nas this) los qhia qhov kev sib txuas no (lub sijhawm xauj), thiab teeb tsa cov npe servers (zoo li saib tus lej xov tooj hauv cov npe).

4. Txuag thiab tawm los ntawm nias "Ctrl - X" thiab tom qab ntawd "y" (thiab tom qab ntawv nkag mus)

Kauj ruam 9: Kho qhov Default DHCP Server File

Cia peb hloov kho DHCP server cov ntaub ntawv kom peb tuaj yeem muab nws tshaj tawm ntawm WiFi! Mus rau DHCP default server file los ntawm kev ntaus cov hauv qab no:

sudo nano/etc/default/isc-dhcp-neeg rau zaub mov

1. Nqes mus rau kab uas hais tias INTERFACES =”” thiab hloov nws mus tshaj tawm ntawm wlan0 (uas yog xoom, tsis yog O):

INTERFACES = "wlan0"

2. Txuag thiab tawm los ntawm nias "Ctrl - X" thiab tom qab ntawd "y" (tej zaum koj yuav xav tias qhov no tawm qhov tseem ceeb ua ke los ntawm tam sim no yog li kuv mam li tsis hais txog nws:)).

Kauj Ruam 10: Teeb IP Static IP Address

sudo nano /etc/hostapd/hostapd.conf

2. Sau cov hauv qab no (raws nraim li yog) hauv daim ntawv teeb tsa tshiab no (tom qab tawm & txuag) (Duab 1):

interface = wlan0

ssid = HelloWorld #Name ntawm koj li RPi WiFi kev sib txuas country_code = US #Unless koj nyob lwm qhov! hw_mode = g channel = 6 macaddr_acl = 0 auth_algs = 1 ignore_broadcast_ssid = 0 wpa = 2 #This yog tus password lo lus zais wpa_passphrase = raspberry #Hloov tus password! wpa_key_mgmt = WPA-PSK wpa_pairwise = CCMP wpa_group_rekey = 86400 ieee80211n = 1 wme_enabled = 1

3. Qhia rau HostAPD raws tu qauv qhov twg thiaj nrhiav tau cov ntaub ntawv tshiab no

Kho kom raug Default HostAPD cov ntaub ntawv:

sudo nano/etc/default/hostapd

Nrhiav kab uas hais tias #DAEMON_CONF = "". Tshem tawm cov lus pom thiab kho kom nws zoo li qhov no (Duab 2):

DAEMON_CONF =”/etc/hostapd/hostapd.conf”

Kho kom raug HostAPD initialization file:

sudo nano /etc/init.d/hostapd

Nrhiav kab uas hais tias DAEMON_CONF =. Kho kom raug nws kom nws taw tes rau koj cov ntaub ntawv teeb tsa tshiab! Zoo li no (Duab 3):

DAEMON_CONF =/etc/hostapd/hostapd.conf

Kauj Ruam 12: Kho Kho Network Chaw Txhais Lus ("NAT")

Cov kauj ruam no tso cai rau ntau tus neeg siv khoom (zoo li txhua tus phooj ywg!) Txuas rau Pi's WiFi ib zaug (ua si txhua qhov kev ua si !!). Nws yog qhov txuj ci me ntsis, yog li kuv yuav ua kom ci ntsa iab dua (tseem tsis paub zoo heev nrog ntu no), tab sis nws yuav ua rau koj hla cov txheej txheem.

1. Ua ntej, peb yuav tsum pib IP xa mus txhua lub sijhawm Pi qhib. Nkag mus rau cov lus txib hauv qab no txhawm rau kho cov sysctl* cov ntawv teeb tsa:

sudo nano /etc/sysctl.conf

- Scroll rau hauv qab thiab ntaus cov cai no ntawm kab tshiab, tom qab ntawd tawm & txuag:

net.ipv4.ip_forward = 1

*btw uas yog L hauv sysctl, tsis yog 1, uas kuv tau messed li ntau zaus -.-

2. Qhib IP xa mus los ntawm kev ntaus ntawv:

Txuas rau Pi, txuas rau WiFi nkag mus rau qhov chaw koj teeb tsa (qhov no yog lub npe "HelloWorld"), thiab khaws lossis rho tawm cov ntaub ntawv los ntawm nws. Koj tuaj yeem nkag tau cov ntaub ntawv no txawm tias koj raug txuas los ntawm Is Taws Nem. Yog li koj tuaj yeem txuag koj cov yeeb yaj kiab nyiam thiab tseem saib nws thaum lub zog tawm:) (er, piv txwv tias koj tau them lub laptop).

Ntxiv cov ntaub ntawv ntau ntxiv (piv txwv li koj tuaj yeem siv nws ua qhov chaw khaws cia), ua si ib puag ncig nrog tus lej HTML kom ua rau koj lub xaib zoo nkauj, thiab muaj kev lom zem!

Lwm qhov kev xaiv yog teeb tsa qhov no los ua nplooj ntawv pej xeem ntsib thiab muab nws lub npe sau cia kom lwm tus neeg tuaj yeem nkag mus saib cov ntaub ntawv. Qhov no muaj txiaj ntsig tshwj xeeb yog tias koj yuav mus qhov twg tsis muaj WiFi lossis cable Internet - koj tuaj yeem nqa Wikipedia nrog koj! (tab sis tej zaum pub dawb rau lawv yog tias koj ua qhov ntawd 'ua rau lawv txaus). Yog tias koj xis nyob nrog cov cai, koj tuaj yeem teeb tsa qhov no los ua tus neeg rau zaub mov thaub qab tsis siv neeg, lub server wireless game hauv zos rau koj thiab koj cov phooj ywg, thiab lwm yam.

Yog tias koj mus rau txoj kev no, nco ntsoov koj paub me ntsis txog kev ruaj ntseg network raws li WPA2 tus password txheej txheem tsis ntev los no tau cuam tshuam (saib hauv qab no).

Thaum kawg, raws li tau hais hauv cov lus qhia, koj tuaj yeem siv Cloud server no los pib ua rau tib neeg Internet! Muaj ib hnub tsim nrog koj cov phooj ywg los tsim pawg Cloud servers kom koj txhua tus tuaj yeem "tham" rau ib leeg! Txoj hauv kev no tsis tas yuav yog * zoo tshaj * (aka zoo tshaj/ua tau zoo) txoj hauv kev los tsim Internet rau pej xeem, tab sis nws yog qhov pib zoo. Ntxiv rau, peb nkag siab zoo li cas cov thev naus laus zis no ua haujlwm, zoo dua peb siv lawv los daws teeb meem loj thiab tawm tswv yim rau peb tus kheej thiab peb cov zej zog.:)

Xav paub ntau ntxiv txog WPA2 kev nyab xeeb kev pheej hmoo los ntawm cov neeg siv muaj txiaj ntsig BillDauterive:

"[T] nws tus neeg tawm tsam xav tau lub cuab yeej nyob hauv thaj tsam ntawm lub hom phiaj wifi network los ua kev hem thawj xws li qhib chaw nres nkoj rau lub vev xaib tsis cuam tshuam qhov ntawd. kev sib txuas ntawm Wifi network uas tsis tau encrypted ntawm TLS. Ntawm qhov cuam tshuam WLAN, tsis nkag siab VNC rau Pi yuav muaj kev pheej hmoo txawm tias nkag los ntawm WLAN."
