NVIDIA Jetson AGX Thor - Accessing the Board via SSH
 | The NVIDIA Jetson AGX Thor documentation from RidgeRun is presently being developed. |
SSH Access
Once Jetson AGX Thor has been flashed and booted into Ubuntu, you can access the board remotely via SSH. This is the preferred method for headless development, scripting, and remote management.
Step 1: Find the IP Address
You must first determine the board's IP address. If you have serial console access or physical access with a display, log in and run:
ifconfig
Look for the IP address under `eth0` (wired Ethernet) or `usb0` (USB virtual networking) depending on how the board is connected.
Example output:
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.0.174 netmask 255.255.255.0 broadcast 192.168.0.255
ether 00:04:4b:cb:9a:f7 txqueuelen 1000 (Ethernet)
RX packets 38 bytes 3894 (3.8 KB)
TX packets 35 bytes 4683 (4.6 KB)
Step 2: SSH into the Board
From your development PC (in the same network), use the default credentials to SSH into the board:
ssh nvidia@192.168.0.174
You'll see a message like this on first connection:
The authenticity of host '192.168.0.174 (192.168.0.174)' can't be established. ECDSA key fingerprint is SHA256:... Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '192.168.0.174' (ECDSA) to the list of known hosts. nvidia@192.168.0.174's password:
If successful, you'll land in the Ubuntu terminal running on Jetson AGX Thor.
Persistent IP Tip
Jetson devices typically obtain an IP via DHCP. To avoid address changes after reboots:
- Configure your router or DHCP server to assign a static IP address based on the board's MAC address.
- Alternatively, set a static IP address directly on the Jetson:
- From the GUI: Open Settings > Network > IPv4 > Manual and set the desired IP.
- From the command line: Use `nmcli` or edit the Netplan configuration files (for Ubuntu 24.04).
