Modem Huawei e3372h - 153

Iyi modem yaive sosi yakakosha yeropa kwandiri, uye, chokwadi, yakave iyo bhodhoro reprojekiti yese. Kazhinji, zita rekuti "modemu" yezvishandiso izvi hariratidzi chinangwa chebasa zvachose: iyi isanganiswa ine simba, iyi chidimbu chehardware ine mudziyo unoumbwa unonyepedzera kunge CD-ROM kuitira kuisa madhiraivha, uye wozochinja kune network kadhi modhi.

Architecturally, kubva pakuona kwemushandisi weLinux, mushure mezvirongwa zvose, zvinoratidzika sezvizvi: mushure mekubatanidza modem, ndine eth * network interface, iyo kuburikidza ne dhcp inogamuchira IP kero 192.168.8.100, uye gedhi rakagadziriswa. is 192.168.8.1.

Uye nguva inonyanya kukosha! Iyi modem modhi haigone kushanda mune modem mode, iyo inodzorwa neAT mirairo. Zvese zvingave zviri nyore, gadzira PPP yekubatanidza kune yega modem uye wobva washanda navo. Asi mune yangu, "iye" (chaizvoizvo, Linux diver maererano nemitemo yeudev), inogadzira eth interface uye inopa IP kero kwairi kuburikidza nedhcp.

Kuti udzivise kuwedzera kuvhiringidzika, ndinokurudzira kukanganwa izwi rekuti "modem" uye kutaura kadhi network uye gedhi, nekuti muchidimbu, zvakafanana nekubatanidza kadhi retiweki nyowani negedhi.
Kana pane modem imwe chete, izvi hazvikonzeri matambudziko akakosha, asi kana paine anopfuura imwe, iyo n-zvidimbu, inotevera network inobuda.

Kureva, n makadhi etiweki, ane kero yeIP yakafanana, imwe neimwe ine gedhi rakafanana. Asi muchokwadi, imwe neimwe yadzo yakabatana kune yayo opareta.

Pakutanga, ini ndaive nemhinduro yakapusa: kushandisa ifconfig kana ip kuraira, dzima zvese zvinopindirana uye ingobatidza imwe nekuiedza. Mhinduro yaive yakanaka kune wese munhu, kunze kwekunge panguva yekuchinja ini handina kukwanisa kubatana kune mudziyo. Uye sezvo kuchinjika kuchiwanzo uye nekukurumidza, ini ndakanga ndisina mukana wekubatana zvachose.

Naizvozvo, ini ndakasarudza nzira yekuchinja nemaoko kero dzeIP dzemodemu uyezve kutyaira traffic uchishandisa marongero enzira.

Uku kwakanga kusiri kuguma kwematambudziko angu nemamodemu: kana matambudziko emagetsi, akadonha, uye simba rakanaka rakagadzika remagetsi ku USB hub raidiwa. Ndakagadzirisa dambudziko iri nekuomesa simba rakananga kune hub. Rimwe dambudziko randakasangana naro uye rakaparadza purojekiti yese: mushure mekutangazve kana kutonhora kutanga kwechigadzirwa, kwete ese modem akaonekwa uye kwete nguva dzose, uye ini handina kukwanisa kuona kuti nei izvi zvakaitika uye nei algorithm. Asi zvinhu zvekutanga kutanga.

Kuti modem ishande nemazvo, ndakaisa iyo usb-modeswitch package.

sudo apt update
sudo apt install -y usb-modeswitch

Mushure meizvozvo, mushure mekubatanidza, iyo modem inozoonekwa uye nekugadziriswa neiyo udev subsystem. Ndinotarisa nekungobatanidza modem uye kuona kuti network inoonekwa.
Rimwe dambudziko randakanga ndisingakwanisi kugadzirisa: ndingawana sei zita remushandisi watiri kushanda naye kubva modem iyi? Zita remushandisi ririmomodemu web interface pa192.168.8.1. Iri peji rewebhu rine simba rinogashira data kuburikidza neAjax zvikumbiro, saka kungo wgeta peji uye kupatsanura zita hazvishande. Saka ndakatanga kutarisa magadzirirwo ewebhu peji, nezvimwe, uye ndakaona kuti ndanga ndichiita zvimwe zvisina maturo. Nekuda kweizvozvo, akapfira mate, uye mushandisi akatanga kugamuchira achishandisa Speedtest API pachayo.

Zvakawanda zvingave nyore kana modem yakawana kuburikidza neAT mirairo. Zvingave zvichigoneka kuigadzirisa zvakare, kugadzira ppp yekubatanidza, kugovera IP, kuwana telecom opareta, nezvimwe. Asi shuwa, ndiri kushanda nezvandakapihwa.

GPS

GPS inogamuchira yandakapihwa yaive neUART interface uye simba. Yakanga isiri iyo yakanakisa mhinduro, asi yaive ichiri kushanda uye iri nyore. Mugamuchiri aitarisa zvakadai.

Kutaura chokwadi, iyi yaive nguva yangu yekutanga kushanda neGPS inogamuchira, asi sezvandaitarisira, zvinhu zvose zvakafungwa kwatiri kare kare. Saka isu tinongoshandisa yakagadzirira-yakagadzirwa mhinduro.

Kutanga, ndinogonesa uart_AO_B (UART_RX_AO_B, UART_TX_AO_B) kubatanidza GPS.

khadas@Khadas:~$ sudo fdtput -t s /dtb.img /serial@c81004e0 status okay

Mushure mezvo ndinoongorora kubudirira kwekushanda.

khadas@Khadas:~$ fdtget /dtb.img /serial@c81004e0 status
okay

Uyu murairo sezviri pachena unogadzirisa devtree panhunzi, iyo iri nyore kwazvo.

Mushure mekubudirira kwekuita uku, tangazve uye isa iyo GPS daemon.

khadas@Khadas:~$ sudo reboot

Kuisa iyo GPS daemon. Ini ndinoisa zvese uye ndozvicheka nekukasira kuti ndiwedzere kugadzirisa.

sudo apt install gpsd gpsd-clients -y
sudo killall gpsd
 
/* GPS daemon stop/disable */
sudo systemctl stop gpsd.socket
sudo systemctl disable gpsd.socket

Kugadzirisa faira rezvigadziriso.

sudo vim /etc/default/gpsd

Ndiri kuisa UART iyo GPS icharembera.

DEVICES="/dev/ttyS4"

Uye zvino tinobatidza zvese uye totanga.

/* GPS daemon enable/start */
sudo systemctl enable gpsd.socket
sudo systemctl start gpsd.socket

Mushure meizvozvo, ini ndinobatanidza iyo GPS.

Iyo GPS waya iri mumaoko angu, iyo UART debugger waya inoonekwa pasi peminwe yangu.

Ini ndinotangazve uye ndinotarisa kushanda kweGPS ndichishandisa chirongwa chegpsmon.

Iwe haugone kuona ma satellite mune ino skrini, asi iwe unogona kuona kutaurirana neGPS inogamuchira, uye izvi zvinoreva kuti zvese zvakanaka.

Mupython, ndakaedza sarudzo dzakawanda dzekushanda nedaemon iyi, asi ndakagara pane iyo yakashanda nemazvo nepython 3.

Ndinoisa raibhurari inodiwa.

sudo -H pip3 install gps3

Uye ndinoveza kodhi yebasa.

from gps3.agps3threaded import AGPS3mechanism

	agps_thread.run_thread()  # Throttle time to sleep after an empty lookup, default '()' 0.2 two tenths of a second

Kana ndichida kuwana marongero, izvi zvinoitwa nekufona kunotevera:

longitude, latitude = getPositionData(agps_thread)

Uye mukati me1-10 masekondi ini ndichawana iyo kurongeka kana kwete. Hongu, ndakaedza gumi kuti ndiwane zvinorongeka. Haisi yakakwana, yakakombama uye yakashata, asi inoshanda. Ndakafunga kuita izvi nekuti GPS inogona kusatambira zvakanaka uye isingagamuchire data. Kana iwe ukamirira kuti ugamuchire data, saka kana ukashanda mukamuri iri kure, chirongwa chinotonhora munzvimbo ino. Naizvozvo, ndakashandisa iyi inelegant sarudzo.

Muchidimbu, kana paine nguva yakawanda, zvaizogoneka kugashira data kubva kuGPS zvakananga kuburikidza neUART, patsanura mune imwe shinda uye kushanda nayo. Asi pakanga pasina nguva zvachose, saka kodhi ine hutsinye yakashata. Uye hongu, handinyare.

Senzira yekutaurirana nehardware, vim2 yakasarudza reverse ssh yekubatanidza uye, sekuratidzira kwakaratidza, haisi iyo yakanyanya kunaka. Kana iyo yekubatanidza ikarasika, sevha inobata chiteshi uye hazvibviri kubatana kuburikidza nayo kwenguva yakati. Naizvozvo, zvichiri nani kushandisa dzimwe nzira dzekukurukurirana, semuenzaniso VPN. Mune ramangwana ndaida kuchinjira kuVPN, asi ndakanga ndisina nguva.

Ini handisi kuzopinda muzvinyorwa zvekumisikidza firewall, kudzora kodzero, kudzima midzi ssh kubatana uye mamwe matruisms ekumisikidza VPS. Ndinoda kutenda kuti iwe unotoziva zvese. Kune yekubatanidza kure, ini ndinogadzira mushandisi mutsva pane server.

adduser vimssh

Ini ndinogadzira ssh makiyi ekubatanidza pane yedu Hardware.

ssh-keygen

Uye ini ndinozvikopa kune yedu server.

ssh-copy-id [email protected]

Pane yedu hardware, ini ndinogadzira otomatiki reverse ssh yekubatanidza pabhoti yega yega.

[Unit] Description=Auto Reverse SSH Requires=systemd-networkd-wait-online.service After=systemd-networkd-wait-online.service [Service] User=khadas ExecStart=/usr/bin/ssh -NT -o ExitOnForwardFailure=yes -o ServerAliveInterval=60 -CD 8080 -R 8083:localhost:22 [email protected] RestartSec=5 Restart=always [Install] WantedBy=multi-user.target

Teerera kuchiteshi 8083: inosarudza kuti ndechipi chiteshi chandichashandisa kubatanidza kuburikidza nereverse ssh. Wedzera iyo kune yekutanga uye tanga.

sudo systemctl enable autossh.service
sudo systemctl start autossh.service

Unogona kuona chimiro:

sudo systemctl status autossh.service

Zvino, pane yedu VPS server, kana tikamhanya:

ssh -p 8083 khadas@localhost

Ndobva ndasvika kune yangu yekuyedza chidimbu chehardware. Uye kubva kune Hardware ini ndinogona zvakare kutumira matanda uye chero data kuburikidza ne ssh kune yangu server, iyo iri nyore kwazvo.

Kuisa zvose pamwe chete

Kubatidza, ngatitange kusimudzira uye kugadzirisa

Phew, ndizvozvo, ndakatsanangura node dzese. Iye zvino yave nguva yekuisa zvese pamwe chete. Iwe unogona kuona iyo kodhi pano pano.

Chinhu chakakosha chine kodhi: Iyi purojekiti inogona kusatanga sezvizvi, nekuti yakarongedzerwa kune rimwe basa, reimwe dhizaini. Kunyange zvazvo ini ndichipa kodhi yekodhi, ndicharamba ndichitsanangura zvinhu zvakakosha pano, mumashoko chaiwo, kana zvisina kudaro hazvinzwisisi zvachose.

Pakutanga, ini ndinotangisa gps, gpio uye kuvhura yakaparadzana scheduler tambo.

#запуск потока планировщика
pShedulerThread = threading.Thread(target=ShedulerThread, args=(1,))
pShedulerThread.start()

Iyo scheduler iri nyore: inotarisa kuona kana nguva yasvika yekutumira mameseji uye kuti chii chazvino chikanganiso chimiro. Kana paine chikanganiso mureza, ipapo isu blink LED.

#sheduler
def ShedulerThread(name):
	global ready_to_send
	while True:
		d = datetime.today()
		time_x = d.strftime('%H:%M')
		if time_x in time_send_csv:
			ready_to_send = True
		if error_status:
			error_blink()
		else:
			good_blink()
		time.sleep(1)

Chikamu chakanyanya kuoma chechirongwa ichi kuchengetedza reverse ssh yekubatanidza kune yega bvunzo. Muedzo wega wega unosanganisira kugadzirisa zvakare gedhi rekutanga uye DNS server. Sezvo pasina anoverenga zvakadaro, ziva kuti chitima hachikwiri pamatanda emapuranga. Ani nani anowana zai reIsita anowana zvihwitsi.

Kuti ndiite izvi, ini ndinogadzira yakaparadzana tafura tafura -set-maka 0x2 uye mutemo wekutungamira traffic.

def InitRouteForSSH():
	cmd_run("sudo iptables -t mangle -A OUTPUT -p tcp -m tcp --dport 22 -j MARK --set-mark 0x2")
	cmd_run("sudo ip rule add fwmark 0x2/0x2 lookup 102")

Unogona kudzidza zvakawanda nezvekuti inoshanda sei verenga mune ino chinyorwa.

Mushure mezvo ini ndinopinda mune isingaperi loop, apo nguva imwe neimwe yatinowana rondedzero yeakabatana modem (kuti tizive kana network configuration yakangoerekana yachinja).

network_list = getNetworklist()

Kuwana rondedzero yetiweki interfaces kuri nyore.

def getNetworklist():
	full_networklist = os.listdir('/sys/class/net/')
	network_list = [x for x in full_networklist if "eth" in x and x != "eth0"]
	return network_list

Mushure mekugamuchira rondedzero, ndinoisa IP kero kune ese mainterfaces, sezvandakaratidza mumufananidzo muchitsauko nezve modem.

SetIpAllNetwork(network_list)

def SetIpAllNetwork(network_list):
	for iface in network_list:
		lastip = "%d" % (3 + network_list.index(iface))
		cmd_run ("sudo ifconfig " + iface + " 192.168.8." + lastip +" up")

Ipapo ini ndinongo pfuura neimwe interface mune loop. Uye ini ndinogadzirisa imwe neimwe interface.

	for iface in network_list:
		ConfigNetwork(iface)

def ConfigNetwork(iface):
#сбрасываем все настройки
		cmd_run("sudo ip route flush all")
#Назначаем шлюз по умолчанию
		cmd_run("sudo route add default gw 192.168.8.1 " + iface)
#задаем dns-сервер (это нужно для работы speedtest)
		cmd_run ("sudo bash -c 'echo nameserver 8.8.8.8 > /etc/resolv.conf'")

Ini ndinotarisa iyo interface yekushanda, kana pasina network, ini ndinoburitsa zvikanganiso. Kana pane network, inguva yekuita!

Pano ini ndinogadzirisa ssh routing kune iyi interface (kana isati yaitwa), tumira zvikanganiso kune sevha kana nguva yasvika, tumira matanda uye pakupedzisira mhanya nekukurumidza uye chengetedza matanda kune csv faira.

if not NetworkAvalible():
....
#Здесь мы формируем ошибки
....
else: #Есть сеть, ура, работаем!
#Если у нас проблемный интерфейс, на котором ssh, то меняем его
  if (sshint == lastbanint or sshint =="free"):
    print("********** Setup SSH ********************")
    if sshint !="free":
      сmd_run("sudo ip route del default via 192.168.8.1 dev " + sshint +" table 102")
    SetupReverseSSH(iface)
    sshint = iface
#раз сетка работает, то давай срочно все отправим!!!
    if ready_to_send:
      print ("**** Ready to send!!!")
        if sendLogs():
          ready_to_send = False
        if error_status:
          SendErrors()
#и далее тестируем скорость и сохраняем логи.

Zvakakodzera kutaura basa rekumisikidza reverse ssh.

def SetupReverseSSH(iface):
	cmd_run("sudo systemctl stop autossh.service")
	cmd_run("sudo ip route add default via 192.168.8.1 dev " + iface +" table 102")
	cmd_run("sudo systemctl start autossh.service")

Uye zvechokwadi, iwe unofanirwa kuwedzera kunaka uku kwekutanga. Kuti ndiite izvi, ndinogadzira faira:

sudo vim /etc/systemd/system/modems_speedtest.service

Uye ndinonyora mairi:

[Unit] Description=Modem Speed Test Requires=systemd-networkd-wait-online.service After=systemd-networkd-wait-online.service [Service] User=khadas ExecStart=/usr/bin/python3.6 /home/khadas/modems_speedtest/networks.py RestartSec=5 Restart=always [Install] WantedBy=multi-user.target

Ini ndinobatidza autoloading ndotanga!

sudo systemctl enable modems_speedtest.service
sudo systemctl start modems_speedtest.service

Ikozvino ndiri kuona matanda ezviri kuitika ndichishandisa murairo:

journalctl -u modems_speedtest.service --no-pager -f

Mhinduro

Zvakanaka, zvino chinonyanya kukosha ndechekuti, chii chakaitika semugumisiro? Heano mashoma magirafu andakakwanisa kutora panguva yekuvandudza uye kugadzirisa maitiro. Iwo magirafu akavakwa pachishandiswa gnuplot ine script inotevera.

Chiitiko chekutanga chaive neTele2 opareta, yandakaita kwemazuva akati wandei.

Pano ndakashandisa dhizaini yekuyera server. Yekumhanyisa kuyerwa kunoshanda, asi kuchinjika zvakanyanya, asi imwe avhareji kukosha ichiri kuoneka, uye izvi zvinogona kuwanikwa nekusefa iyo data, semuenzaniso, neavhareji inofamba.

Gare gare ndakagadzira akati wandei magirafu evamwe vafambisi venhare. Muchiitiko ichi, pakanga patova nesevha imwe yekuedza, uye migumisiro yacho yainakidzawo.

Sezvauri kuona, musoro wacho wakakura kwazvo pakutsvaga nekugadziriswa kweiyi data, uye zvakajeka haigare kwemavhiki mashoma ebasa. Asi…

Mhedzisiro yebasa

Basa racho rakangoerekana rapera nekuda kwemamiriro ezvinhu andakanga ndisingakwanisi kuita. Imwe yehutera hwepurojekiti iyi, mumaonero angu, yaive modem, iyo yaisanyatsoda kushanda panguva imwe chete nemamwe modem, uye yaiita matipi akadaro pese payaiiswa. Nezvinangwa izvi, kune nhamba huru yemamwe mamodemu modhi; kazhinji anenge atove muMini PCI-e fomati uye akaiswa mukati memudziyo uye ari nyore kugadzirisa. Asi iyo inyaya yakasiyana zvachose. Basa racho rainakidza uye ndakafara zvikuru kuti ndakakwanisa kutora chikamu mariri.
