Configurare USB over IP Server pe Ubuntu 2X.04 LTS

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 sau modem 4G/5G.

Instalare usbip

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

Startup usbip

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=USB/IP Host Service 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

Module usbip

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

usbip_core usbip_host vhci_hcd

Adaugare dispozitive USB server

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

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

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
