Missing firewall service

Hopefully this is the correct place to post this question I have about missing services.

This is my platform:

  • Jetson AGX Orin 64GB
  • Ubuntu 22.04 host and target
  • JetPack 6.0 (rev 2)
  • developer kit version
  • DeepStream 7.0, and all target components included

Does anyone know if there is a firewall service enabled by default? I remember it was ufw, but I do not see it installed. Platform Services indicates it is. I also cannot find jetson-firewall:

root@ubuntu:~# service jetson-firewall status
Unit jetson-firewall.service could not be found.
…
root@ubuntu:~# ufw status
-bash: ufw: command not found

What do you see from the following:

  • dpkg -l | grep -i 'ufw'
  • systemctl status ufw.service
  • apt search ufw
    (requires networking)

root@ubuntu:~# dpkg -l | grep -i ‘ufw’
root@ubuntu:~# systemctl status ufw.service
Unit ufw.service could not be found.
root@ubuntu:~# apt search ufw

plasma-firewall/jammy 5.24.4-0ubuntu1 arm64
Plasma configuration module for firewalls

ufw/jammy-updates 0.36.1-4ubuntu0.1 all
program for managing a Netfilter firewall

So I can manually install ufw, but shouldn’t it be there already after flashing?

No. That’s Ubuntu by default. NVIDIA did not design Ubuntu, they only added drivers and boot support. It is true though that installation media on a PC might offer more options, but normally you would need this:
sudo apt-get install ufw
(you might also want the GUI version, gufw)
