SSH Access on Jetson Orin Nano

1. Turn on the Jeton Nano, wait a few minutes for it to boot up and start the bluetooth service
2. Connect to msoe-nano1 via bluetooth
   • On Windows 11, open Settings > Bluetooth & devices > Devices > View more devices
   • Under "Device Settings," set "Bluetooth devices discovery" to "Advanced"
   • Click "Add device" and select "Bluetooth" then select msoe-nano1 from the list
   • Once connected, find msoe-nano1 in the list of devices, click the three dots next to it, and select "Join Person Area Network (PAN)"
   • Select "Access Point" from the dropdown and click "Connect"
3. Next, edit C:\Users\%USERNAME%\.ssh\config You can open it in VSCode with this command:

   code C:\Users\%USERNAME%\.ssh\config
   

4. Add this to the file:

   Host msoe-nano*
       HostName 192.168.100.1
       User msoe
   

5. Save the file
6. After updating your SSH config file, run this command to check if you have an SSH key made:

   dir C:\Users\%USERNAME%\.ssh
   

7. If you see a file ending in .pub, skip this step. Otherwise, run this command and don't forget to replace with your email. Type enter to accept the default options for file location and to leave the passphrase blank.

   ssh-keygen -t ed25519 -C "your_email@example.com"
   

8. Run this command (change the path to the SSH key if needed), enter the password for the Jetson Nano user, then type exit to close the connection

   type C:\Users\%USERNAME%\.ssh\id_ed25519.pub | ssh msoe-nano1 "cat >> ~/.ssh/authorized_keys"
   

9. In a new command prompt, run this command

   ssh msoe-nano1
   

10. Check that you see this:

    msoe@msoe-nano1:~$ 
    

11. If you do, congrats! You're all set to run commands on the Jetson Nano from your device!
