Is there a Firewall in the Fedora Live o/s versions for internet use?

I use live versions of Fedora that I write to thumb drives. Is there a firewall on these live versions, I do not see firewalld in the Activities Applications menu? Maybe there is one on these versions that is hidden? I attempted to go into the software menu and install and also tried the terminal window command shell and typed in: dnf install firewalld. The return message was need super user (normal reply) yet there is no root password that I am aware of to use for passage with the live version, again the sudo would also require a user password for someone with administrative privilege. Is it safe to use these live versions for on-line internet use without a firewall if none is hidden in the o/s live version? If not, may I make a suggestion that developers should add a default version of the firewalld application or any other that would be easy to use on the live versions of Fedora that run on DVD’s or thumb drives.

In a previous forum topic here I was warned against using older operating systems that have reached end of life support. I explained how I like a lot of the software on older versions for older computers since a lot no longer is available in newer versions of Fedora o/s. On older computer I have manually installed the repository from DVDs that I purchased for that version of the operating system that works well without internet dependency. For occasional use on the internet I decided to take your advice found here and instead run a live version of the latest operating system from a thumb drive that includes the latest version of Firefox and most likely the latest security updates?
These live versions are also handy for using at a library locally where the only operating system they have is Windows. Your Fedora live versions work well at library.
Also notice that on the last version you are locked out without password to any other directories in other partitions when using these live versions. That seems to me a good security feature since some other versions of Linux leave these directories on other partitions open without any password to dig into.

  1. In the live version, you can use sudo, since it is configured to not require a password, it will just execute the command. So, if you want to install a program in the live environment, just use sudo dnf install firewalld

  2. You can check if firewalld is running with systemctl status firewalld command. Since there is no graphical frontend installed in the live environment, you don’t see it in the application menu.


Thanks for this information. Typed in: systemctl status firewalld.
The return looks like there is a firewall there.
If I had tried the dnf install firewalld command first that would probably return an already installed message. Thank you for your time and consideration, most appreciated.
