There is no ConfigServer Security & Firewall in this
Your screenshot -is- from Configserver Security & Firewall.
As said, not everything be done via Directadmin panel, some settings in the csf.conf need to be done via SSH.
MC is not intended to connect with SSH. You can use it when you are already logged in via SSH.
If you are on Ubuntu, then you need another command to install MC, try this:
sudo apt install mc
after installation you can start just by typing
mc
and it looks a bit like Total Commander in Windows.
However, I would suggest to use nano to edit the csf.conf file to prevent risk of odd things by the build in MC editor.
If not installed you can install it the same way:
sudo apt install nano
and then edit like this:
Code:
cd /etc/csf
nano csf.conf
On the bottom of the editor is shown what you can do like ctrl-x to close and if something is change you can use y to confirm changes.
Don't forget to restart csf and lfd after making changes:
csf -ra
