Kusintha kwa USB/IP

Ntchito yolumikiza chipangizo cha USB ku PC yakutali kudzera pa netiweki yakomweko imakhalapo nthawi zonse. Pansi pa odulidwawo pali mbiri yakusaka kwanga kumbali iyi, ndi njira yopita ku yankho lokonzekera lokhazikitsidwa ndi polojekiti yotseguka. USB/IP ndi kufotokoza zopinga anaika mosamala ndi anthu osiyanasiyana panjira imeneyi, komanso njira circumvent iwo.

Gawo loyamba, mbiri

Ngati makinawo ndi enieni, zonsezi ndi zophweka. Kugwira ntchito kwa USB kutumiza kuchokera kwa wolandirayo kupita kumakina enieni adawonekera mu VMWare 4.1. Koma kwa ine, kiyi yachitetezo, yodziwika kuti WIBU-KEY, idayenera kulumikizidwa ndi makina osiyanasiyana nthawi zosiyanasiyana, osati zenizeni zokha.
Kufufuza koyamba mu 2009 kunanditsogolera ku chida chotchedwa hardware TrendNet TU2-NU4
Zotsatira:

• nthawi zina zimagwiranso ntchito

Wotsatsa:

• sizimagwira ntchito nthawi zonse. Tinene kuti kiyi yachitetezo cha Guardant Stealth II sichiyambira pamenepo, kulumbira ndi cholakwika "chipangizocho sichingayambike."
• Mapulogalamu oyang'anira (werengani: kuyika ndi kutsitsa zida za USB) ndizovuta kwambiri. Kusintha kwa mzere, makina - ayi, sitinamvepo. Zonse zimachitika ndi manja anu. Maloto owopsa.
• Pulogalamu yowongolera imasaka ma Hardware pamaneti powulutsa, kotero imagwira ntchito mkati mwa gawo limodzi lowulutsa la netiweki. Simungathe kufotokoza adilesi ya IP ya chipangizocho pamanja. Kodi chidutswa cha hardware chili pa subnet ina? Ndiye muli ndi vuto.
• Madivelopa asiya kugwiritsa ntchito chipangizocho, kutumiza malipoti a cholakwika sikuthandiza.

Kuzungulira kwachiwiri kunachitika munthawi yochepa kwambiri, ndipo idanditsogolera kumutu wankhaniyo - Pulogalamu ya USB/IP. Amakopa ndi kumasuka kwake, makamaka kuyambira anyamata ochokera Yankhani adasainira dalaivala wawo Windows, kotero tsopano chilichonse chimagwira ntchito ngakhale pa x64 popanda njira zina zothanirana ndi vutoli monga mayeso. Zikomo kwambiri kwa gulu la ReactOS chifukwa cha zimenezo! Zonse zikumveka bwino, tiyeni tiyesere kuti tiwone ngati ndi zoonadi. Tsoka ilo, pulojekitiyi yasiyidwa, ndipo chithandizo chikuvuta kupeza—koma tikugwirabe ntchito, source code ilipo, tidzamvetsa!

Gawo lachiwiri, seva-Linux

Seva ya USB/IP yomwe imagawana zida za USB pa netiweki imatha kukhazikitsidwa mu Linux-yochokera ku OS. Chabwino, Linux ndi Linux, choncho tiyeni tiyike pa makina enieni. Debian 8 mu kasinthidwe kochepa, kayendedwe kabwino ka dzanja:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install usbip

Kukhazikitsidwa. Kenako intaneti ikuwonetsa kuti muyenera kutsitsa gawo la usbip, koma - moni, choyamba. Palibe gawo loterolo. Izi zili choncho chifukwa mabuku ambiri pa netiweki amatchula nthambi yakale 0.1.x, ndipo mu 0.2.0 yaposachedwa ma module a usbip ali ndi mayina osiyanasiyana.

Choncho:

sudo modprobe usbip-core
sudo modprobe usbip-host
sudo lsmod | grep usbip

Chabwino, tiyeni tiwonjezere mizere yotsatirayi ku /etc/modules kuti tiyike yokha dongosolo likayamba:

usbip-core
usbip-host
vhci-hcd

Tiyeni tiyambe seva ya usbip:

sudo usbipd -D

Kupitilira apo, nzeru zapadziko lonse lapansi zimatiuza kuti usbip imabwera ndi zolemba zomwe zimatilola kuyang'anira seva - wonetsani chipangizo chomwe chidzagawire pa intaneti, onani momwe ziliri, ndi zina zotero. Apa chida china chamunda chimatiyembekezera - zolemba izi munthambi ya 0.2.x, zasinthidwanso. Mukhoza kupeza mndandanda wa malamulo ntchito

sudo usbip

Pambuyo powerenga malongosoledwe a malamulowo, zikuwonekeratu kuti kuti mugawane chida chofunikira cha USB, usbip akufuna kudziwa ID yake ya Basi. Okondedwa owonerera, tenga nambala yachitatu pabwalo: ID ya Basi yomwe ingatipatse lsusb (zikuwoneka ngati zodziwikiratu) - sizimuyenerera! Chowonadi ndi chakuti usbip imanyalanyaza zida ngati ma hubs a USB. Chifukwa chake, tigwiritsa ntchito lamulo lokhazikika:

user@usb-server:~$ sudo usbip list -l
 - busid 1-1 (064f:0bd7)
   WIBU-Systems AG : BOX/U (064f:0bd7)

Chidziwitso: apa ndi kupitilira mumindandanda ndifotokoza chilichonse pogwiritsa ntchito kiyi yanga ya USB. Dzina lanu la hardware ndi VID: PID awiri akhoza kukhala osiyana. Yanga imatchedwa Wibu-Systems AG: BOX/U, VID 064F, PID 0BD7.

Tsopano titha kugawana chida chathu:

user@usb-server:~$ sudo usbip bind --busid=1-1
usbip: info: bind device on busid 1-1: complete

Zikomo, abwenzi!

user@usb-server:~$ sudo usbip list -r localhost
Exportable USB devices
======================
 - localhost
        1-1: WIBU-Systems AG : BOX/U (064f:0bd7)
           : /sys/devices/pci0000:00/0000:00:11.0/0000:02:00.0/usb1/1-1
           : Vendor Specific Class / unknown subclass / unknown protocol (ff/00/ff)

Zitatu zabwino, abwenzi! Seva yagawana zida pamanetiweki, ndipo titha kuyilumikiza! Zomwe zatsala ndikuwonjezera autostart ya usbip daemon mu /etc/rc.local

usbipd -D

Gawo lachitatu, kasitomala-mbali ndi zosokoneza

Lumikizani chipangizo chogawana ndi makina omwe akuyendetsa netiweki Debian Ndinayesa nthawi yomweyo pa seva yomweyo, ndipo zonse zinalumikizana bwino:

sudo usbip attach --remote=localhost --busid=1-1

Tiyeni tipitirire ku WindowsKwa ine zinali Windows Server Kope Lokhazikika la 2008R2. Buku lovomerezeka likupempha kuti muyike dalaivala kaye. Njirayi yafotokozedwa bwino mu readme yomwe ili ndi kasitomala wa Windows; tinatsatira malangizo ndipo zonse zinayenda bwino. Imagwiranso ntchito popanda vuto lililonse pa XP.

Titamasula kasitomala, timayesetsa kuyika kiyi yathu:

C:Program FilesUSB-IP>usbip -a %server-ip% 1-1
usbip err: usbip_network.c: 121 (usbip_recv_op_common) recv op_common, -1
usbip err: usbip_windows.c: 756 (query_interface0) recv op_common
usbip err: usbip_windows.c: 829 (attach_device) cannot find device

O o. Chinachake chalakwika. Tiyeni tigwiritse ntchito luso la Google. Pali zonena zapang'onopang'ono kuti china chake sichili bwino ndi zokhazikika; mu gawo la seva, opanga adasintha mtundu wa protocol posunthira ku mtundu 0.2.0, koma mu kasitomala wa Win adayiwala kuchita izi. Njira yothetsera vutoli ndikusintha nthawi zonse mu code source ndikumanganso kasitomala.

Koma sindikufuna kutsitsa Visual Studio panjira iyi. Koma ndili ndi Hiew wakale wabwino. Mu code source, nthawi zonse imalengezedwa ngati mawu awiri. Tiyeni tiyang'ane 0x00000106 mufayilo, m'malo mwake ndi 0x00000111. Musaiwale, dongosolo la byte ndilosintha. Zotsatira zake ndi machesi awiri, timayika:

[usbip.exe]
00000CBC: 06 11
00000E0A: 06 11

Aaaandi... yes!

C:Program FilesUSB-IP>usbip -a %server-ip% 1-1
new usb device attached to usbvbus port 1

Uku kukanakhala kutha kwa nkhaniyi, koma nyimbo sizinayimbidwe kwa nthawi yayitali. Nditayambiranso seva, ndidazindikira kuti chipangizocho sichinakhazikitsidwe!

C:Program FilesUSB-IP>usbip -a %server-ip% 1-1
usbip err: usbip_windows.c: 829 (attach_device) cannot find device

Ndipo ndi zimenezo. Ngakhale Google wodziwa zonse sanathe kuyankha izi. Pakadali pano, lamulo lowonetsa zida zomwe zilipo pa seva likuwonetsa bwino kwambiri—nayi, kiyi, mutha kuyiyika. Ndikuyesera kuyiyika kuchokera pansi Linux - Zimagwira ntchito! Ndipo ngati tiyesa kuchokera pansi WindowsO, zoopsa - zimagwira ntchito!

Vuto lomaliza: pali chinachake chomwe chikusowa mu khodi ya seva. Mukagawana chipangizo, sichimawerenga chiwerengero cha mafotokozedwe a USB kuchokera pamenepo. Ndipo mukayika chipangizo kuchokera pansi pake Linux, gawo ili ladzazidwa. Mwatsoka, ndi chitukuko chomwe chili pansi pa Linux Ndikudziwa bwino mawu akuti "make && make install." Choncho vutoli linathetsedwa ndi njira yolakwika kwambiri—kuwonjezera pa /etc/rc.local

usbip attach --remote=localhost --busid=1-1
usbip port
usbip detach --port=00

Gawo lomaliza

Pambuyo pa zovuta zina, zimagwira ntchito. Zomwe zimafunidwa zakwaniritsidwa, tsopano fungulo likhoza kukwera ku PC iliyonse (ndi kuchotsedwa, ndithudi,), kuphatikizapo kunja kwa gawo lofalitsa la intaneti. Ngati mukufuna, mutha kuchita izi pogwiritsa ntchito chipolopolo cholamula. Chosangalatsa ndichakuti chisangalalo ndi chaulere.
Ndikukhulupirira kuti zomwe ndakumana nazo zithandiza omwe akubera kuti azungulire zomwe zalembedwa pamphumi panga. Zikomo chifukwa chakumvetsera!
