Configurare USB over IP Server pe Ubuntu 2X.04 LTS[edit | edit source]

Intr-un mediu enterprise in care se lucreaza cu foarte multe stiick-uri USB este nevoie ca acestea sa fie plasate intr-un mediu centralizat la care intreaga infrastuctura sa aiba acces. Prin intermediul USBIP stick-urile pot fi plasate intr-o singura locatie indiferent daca acestea sunt stick-uri de stocare, certificate SSL, semnaturi digitale, YubiKey-uri, modem 4G/5G sau Web Camera.

Instalare usbip[edit | edit source]

USBIP face parte in Ubuntu 2X.44 din luita de tool-uri linux-tools-generic. Pentru instalare se executa in consola:

# apt install linux-tools-generic

Se verifica daca kernelul are modulele disponibile:

# lsmod | grep usbip

...in unele situatii fiind necesara instalarea unor pachete specifice:

# apt install linux-tools-5.15.0-43-generic linux-cloud-tools-5.15.0-43-generic

Module usbip[edit | edit source]

USBIP are nevoie de 3 module dintre care doua de USB/IP si unul de virtual host controller

# modprobe usbip_core # modprobe usbip_host # modprobe vhci_hcd

Pentru ca aceste module sa fie activate la startup-ul de OS se adauga in lista de module incarcabile:

  • nano /etc/modules-load.d/modules.conf

usbip_core usbip_host vhci_hcd

Startup usbip[edit | edit source]

Pentru ca aplicatia sa porneasca la odata cu systemului de operare se creeaza un fisier de startup un systemctl

  • nano /etc/systemd/system/usbipd.service

[Unit] Description=USBIP Host Server After=network.target [Service] ExecStart=/usr/bin/usbipd -D ExecStop=/usr/bin/usbip --tcp-port 3240 --log Restart=on-failure User=root Type=forking StartLimitBurst=5 StartLimitIntervalSec=10 [Install] WantedBy=multi-user.target

Dupa creerea serviciului se executa:

# systemctl enable --now usbipd.service # systemctl status usbipd.service ● usbipd.service - USB/IP Host Service Loaded: loaded (/etc/systemd/system/usbipd.service; enabled; vendor preset: enabled) Active: active (running) since Fri 2024-04-12 18:03:02 EEST; 25min ago Process: 696 ExecStart=/usr/bin/usbipd -D (code=exited, status=0/SUCCESS) Main PID: 728 (usbipd) Tasks: 1 (limit: 2220) Memory: 800.0K CPU: 18ms

Adaugare dispozitive USB server[edit | edit source]

Din acest moment dispozitivele USB pot fi adaugate in system. Mai jos este prezentat modul in care se face passtrue dispozitivelor USB intr-un hypervisor Proxmox VM

Dupa ce dispozitivele USB sunt adaugate fizis se trece la atasarea acestora in server:

Listare dispozitive USB[edit | edit source]

Listam dispozitivele USB atasate cu comanda lsusb:

# lsusb Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 002 Device 005: ID 090c:1000 Silicon Motion, Inc. - Taiwan (formerly Feiya Technology Corp.) Flash Drive Bus 002 Device 002: ID 13fe:4200 Kingston Technology Company Inc. Platinum USB drive mini

Pentru a vedea ce dispozitive pot fi parsate de catre aplicatie rulam:

# usbip list -p -l busid=2-2#usbid=13fe:4200# busid=2-4#usbid=090c:1000#

Atasarea dispozitive USB[edit | edit source]

Pentru a afla BUSID-ul fiecatui dispozitiv asa cum este inregistrat de usbip rulam:

# usbip list -l - busid 2-2 (13fe:4200) Kingston Technology Company Inc. : Platinum USB drive mini (13fe:4200) - busid 2-4 (090c:1000) Silicon Motion, Inc. - Taiwan (formerly Feiya Technology Corp.) : Flash Drive (090c:1000) Vom atasa serverului cele doua dispozitive listate anterior:

# usbip bind -b 2-2 usbip: info: bind device on busid 2-2: complete # usbip bind -b 2-4 usbip: info: bind device on busid 2-4: complete

Atasarea dispozitive USB la pornirea OS[edit | edit source]

Pentru binding-ul dispozitivelor USB la pornirea de OS se ceeaza cate un serviciu de sistemd pentru fiecare dispozitiv in parte:

  • nano /etc/systemd/system/usbip_bus22.service

[Unit] Description=USB-IP Device Binding BUS 2-2 After=network-online.target Wants=network-online.target Requires=usbipd.service [Service] Type=oneshot ExecStart=/usr/bin/usbip bind --busid 2-2 [Install] WantedBy=multi-user.target # systemctl enable usbip_bus22.service

* Requires=usbipd.service este adaugat pentru ca bind-ul sa fie facut dupa ponirea aplicatiei de usbip

* Type=oneshot bind-ul este o actiune de se executa o singura data. Ne fiind un serviciu in sine systemctl status usbip_bus22.service va arata serviciul ca dead dar actiunea de bind este indeplinits


Configurare USB over IP Client pe Ubuntu 2X.04 LTS[edit | edit source]

Instalare usbip[edit | edit source]

Instalarea de usbip client se face la fel ca si cea de server inclusiv modulele insa nu mai este cazul ca serviciul de systemd sa fie activat


Listare dispozitive USB[edit | edit source]

Inainte de a atasa un dispozitiv USB montat din server facem o listare a dispozitivelor deja existente.

# lsusb Bus 001 Device 002: ID 0627:0001 Adomax Technology Co., Ltd QEMU USB Tablet Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

... iar apoi listam dispozitivele disponibile in server

# usbip list -r 192.168.1.203 Exportable USB devices ====================== - 192.168.1.203 2-4: Silicon Motion, Inc. - Taiwan (formerly Feiya Technology Corp.) : Flash Drive (090c:1000)  : /sys/devices/pci0000:00/0000:00:1e.0/0000:02:1b.0/usb2/2-4  : (Defined at Interface level) (00/00/00) 2-2: Kingston Technology Company Inc. : Platinum USB drive mini (13fe:4200)  : /sys/devices/pci0000:00/0000:00:1e.0/0000:02:1b.0/usb2/2-2  : (Defined at Interface level) (00/00/00)


Atasarea dispozitive USB[edit | edit source]

Dupa identificarea busid-ului fiecarui dispozitiv disponibil in server (2-2 si 2-4 in cazul de fata), atasam dispozitivele USB la masina client

# usbip attach -r 192.168.1.203 -b 2-2 # usbip attach -r 192.168.1.203 -b 2-4

... si verificam faptul ca acestea au fost atasate:

# usbip port -l Imported USB devices ==================== Port 00: <Port in Use> at High Speed(480Mbps) Kingston Technology Company Inc. : Platinum USB drive mini (13fe:4200) 2-1 -> usbip://192.168.1.203:3240/2-2 -> remote bus/dev 002/002 Port 01: <Port in Use> at High Speed(480Mbps) Silicon Motion, Inc. - Taiwan (formerly Feiya Technology Corp.) : Flash Drive (090c:1000) 2-2 -> usbip://192.168.1.203:3240/2-4 -> remote bus/dev 002/003

... iar apoi verificam dispozitivele usb disponibile in masina virtuala:

# lsusb Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 002 Device 003: ID 090c:1000 Silicon Motion, Inc. - Taiwan (formerly Feiya Technology Corp.) Flash Drive Bus 002 Device 002: ID 13fe:4200 Kingston Technology Company Inc. Platinum USB drive mini Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 002: ID 0627:0001 Adomax Technology Co., Ltd QEMU USB Tablet Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Atasarea dispozitive USB la pornirea OS[edit | edit source]

Pentru binding-ul dispozitivelor USB la pornirea de OS se ceeaza cate un serviciu de sistemd pentru fiecare dispozitiv in parte:

  • nano /etc/systemd/system/usbip_bus22.service

[Unit] Description=USB-IP Device Binding BUS 2-2 After=network-online.target Wants=network-online.target [Service] Type=oneshot ExecStart=/usr/bin/usbip attach -r 192.168.1.203 -b 2-4 [Install] WantedBy=multi-user.target # systemctl enable usbip_bus22.service
