NVIDIA Jetson Orin NX- Accessing the Orin board via SSH
To access the Orin NX board via SSH, you'll need to find the IP address of your board first. If you have serial console access or access through keyboard, mouse adn display, use the ifconfig command to get the required information:
nvidia@jetson-0423318029309:~$ ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.0.174 netmask 255.255.255.0 broadcast 192.168.0.255
inet6 fe80::1d2b:ff54:4538:7592 prefixlen 64 scopeid 0x20<link>

RX errors 0 dropped 0 overruns 0 frame 0
TX packets 35 bytes 4683 (4.6 KB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
device interrupt 40
...
After that, you'll be able to access the board from a computer in the same network using the nvidia user, password nvidia:

In general, the board will try to keep using the same IP address when getting it via DHCP. However, consider configuring your DHCP server or your router to provide a static IP address to your board to avoid the IP address to change without notice.
