SSH Reverse Tunneling

1. Start a SSH Server on you local machine.

2. Someone with cu access must do:sh -fN -R 7090:localhost:23 keerthi@your_public_ip

   • -f: Fork to background # I think we can drop this flag
   • -N: Dont execute any command
   • -R: Do port forwarding This will bind 7090 on your machine to 22 on the CU.

From the USB/IP site:

USB/IP Project aims to develop a general USB device sharing system over IP network. To share USB devices between computers with their full functionality, USB/IP encapsulates "USB I/O messages" into TCP/IP payloads and transmits them between computers. Goes without saying, make sure host and client are on the same network.

Host Setup

• Install usbip package

ssh -L 8080:localhost:8021 [email protected] python -m jupyter notebook --port=8021

To use devices inside your nspawn container do:

Edit systemd-nspawn@<machine_name>.service and add a line like the below

DeviceAllow="/dev/serial/by-id/usb-Roboteq_Motor_Controller_SDC2XXX-if00 rwm"
DeviceAllow=char-ttyACM rwm
DeviceAllow=char-usb_device rwm
DeviceAllow=ttyACM rwm

To see valid device types do:

<launch>
  <node name="sbg_device" pkg="sbg_driver" type="sbg_device" output="screen">
        <rosparam command="load" file="/home/suraj/ws/tmp/sbg/sbg.yaml" />
  </node>
</launch>
