why my firewalld shows 2 output
 

i'm still new and learning about centOS 7 ..


then when i explore on my centOS 7 PC, i'm just wondering after i run the command rpm -qa | grep firewalld it shows 2 output:


firewalld-0.5.3-5.el7.noarch
firewalld-filesystem-0.5.3-5.el7.noarch



i mean i watch Youtube centOS7 tutorials but in it, it only shows 1 output which is firewalld-0.5.3-5.el7.noarch


i'll cheerish a lot if you can help me :)




thanks.

Since you're a CentOS user....

It may (or may not) be required, depending on what other software is installed that interfaces to firewalld. I note the following is mentioned...

Help yourself - packages can be queried from a terminalSee the manpage.

syg00, CentOS still uses yum, and not dnf yet. So that would actually be the following instead;

Oops - thanks for that. Believe it or not I have actually installed CentOS 7, but it didn't last long. Obviously ... :eek:

Well, dnf is coming to CentOS, it's only a matter of time. I can't say what CentOS's developers are thinking, but I'd expect that it might be when the CentOS 8.x series are released, that yum will be replaced by dnf. From what I've seen, most of the options are the same or very similar anyway.
