Firewalld on Centos7
Is there any file that one can go in to modify it like the iptables? I just changed the ssh port with this following command below but would like to view the file.
firewall-cmd --permanent --zone=public --add-port=55
Thanks,
TT

You should be able to view the file in the terminal.
Use the cat cmd to look at the file.
For example if I want to view my lilo.conf file I just run this in the terminal.
So basically just run cat <name of file>
If you have trouble finding the file just use the locate or find cmd.
cmd means command.

I am asking for the location of the file. firewalld.conf doesn't seem to have that configuration change. In the old days, iptables was the file. It is supposed to be in /etc/firewalld/firewalld.conf but I don't see anything reflecting the new port change.

Dang:-
Does Firewalld have configuration files or port files that you could go through to find what you want?

I personally just uninstall firewalld and re-install iptables, unfortunately ipsets implementation in CentOS 7 is a bit buggy due to lacking properly systemd script.
Code:
systemctl stop firewalld
systemctl disable firewalld
yum remove firewalld
yum install iptables-services iptables
systemctl enable iptables
systemctl start iptables
Oddly, you still need to use "service iptables save" to save the config, or directly edit /etc/sysconfig/iptables I believe.

On fedora anyway, the firewalld files are in /etc/firewalld
But I don't think it's a good idea to edit files directly, you can do what you need with the firewallcmd admin program.

Is it easier to work with iptables verses firewalld?

Agreed. Some configuration files should not be edited unless one really knows what he or she is doing.
