NVidia Jetson Orin Nano - Network Discovery & Node Naming

NVidia Jetson Orin Nano - Network Discovery & Node Naming

1. Network Discovery & Node Naming
   
   
   • Assign hostnames like:
     
     
     jetson-ai-01.local
     jetson-ai-02.local
     pi-comm-01.local
     pi-db-01.local
     pi-monitor-01.local
     
   • Use hostnamectl set-hostname <name> on each unit.
2. SSH Configuration
   
   
   • From your Freedom Machine:
     
     ssh-keygen -t rsa
     ssh-copy-id [email protected]
     ssh-copy-id [email protected]
     
     
     That way, you can orchestrate all devices without typing passwords.
3. Network File Share
   
   
   • Use Samba or NFS for shared builds.
   • Example NFS export:
     
     >/mnt/cluster_share *(rw,sync,no_subtree_check)
4. Install Cluster Tools
   
   
   • On Ubuntu host:
     
     sudo apt install net-tools htop nmap git docker.io
   • For the Pi/Jetson cluster:
     
     sudo apt install python3-pip
     pip install paho-mqtt flask
5. Verify Jetson AI SDK
   
   
   • Test with:
     
     sudo apt list --installed | grep nvidia
   • Ensure jetson-inference and CUDA runtime libraries are listed.
