USB over IP

Setup USB server on LAN

USB Server Setup (Raspberry Pi, ARM, VirtualHere)

1. wget http://www.virtualhere.com/sites/default/files/usbserver/vhusbdarm
2. chmod +x ./vhusbdarm
3. sudo ./vhusbddarm
4. USB Devices can now be reached

Make persistant

1. Open crontab as root sudo crontab -e
2. Add entry @reboot /path/to/vhusbdarm

USB Client Setup (CLI, Linux, VirtualHere -- Fixme free version, no daemon support)

macOS

1. Download macOS installer from VirtualHere
2. VirtualHere Client should automatically detect server

Windows

1. Download Windows installer from VirtualHere
2. Run vhui64.exe
3. Right click Hubs, Specify Hubs
4. Enter in IP address of the server and port (7575)
   • e.g. 192.168.0.104:7575

Linux

1. mkdir vhclient && cd vhclient
2. wget http://virtualhere.com/sites/default/files/usbclient/vhclientx86_64
3. chmod +x vhclientx86_64
4. sudo ./vhclientx86_64 &

Interact as normal user

1. ./vhclientx86_64 -t "MANUAL HUB ADD,HOSTNAME:PORT" #####FIXME #####
2. ./vhclientx86_64 -t "LIST"
3. ./vhclientx86_64 -t "USE,device.num" #####FIXME #####
4. Should say "OK". Device will now list in USB devices
5. Once device is done being used: ./vhclientx86_64 -t "STOP USING,device.num" #####FIXME #####

USB Client Setup (GUI, Windows, VirtualHere)

1. Install cilent here
2. To connect to WAN (Windows):

• Right Click, Specify Hubs, Add
• Type in HOST:PORT #####FIXME #####

WAN Configuration

Dynamic DNS Update (CLI, Linux, DuckDNS)

1. mkdir duckdns && cd duckdns
2. vi duck.sh
3. Add the line: #####FIXME #####

echo url=”https://www.duckdns.org/update?domains=DOMAIN&token=TOKEN&ip=” | curl -k -o ~/duckdns/duck.log -K -

• domains=DOMAINS provided by duckdns
• token=TOKEN provided by duckdns
• ip= is to be an empty string, duckdns automatically detects client's IP address if left empty

1. chmod 700 duck.sh
2. Test the script

• ./duck.sh
• cat duck.log should only contain the word "OK"

1. Create a cronjob to run the script every 5 minutes:

• crontab -e
• */5 * * * * ~/duckdns/duck.sh >/dev/null 2>&1

Setup Auth

Virtual Here documentation can be found here

1. Make sure ./vhusbddarm is not running before editing config.ini
2. sudo vi config.ini
3. Add the line:

clientAuthorization=/home/pi/auth.sh “$PASSWORD$”

1. vi auth.sh to create a script
2. Add: ######FIXME ######

#!/bin/bash
# Example script for performing basic user authorization for virtualhere
# Also includes a simple password protection mechanism for accessing a device
# Return 2 if the user needs to provide a password (or the password is incorrec$
# Return 1 if the user is allowed to access this device
# Return 0 if the user is not allowed to access this device
# Parameters are passed in as:
# $1 = PASSWORD

logger "Authorizing -> '$1'"
# "mypassword" = " " as an MD5 hash

if [ "$6" == " " ]; then
logger "Authorized!"
exit 1
else
exit 2
