How To Unblock IP address from command line in CSF Firewall

In order Unblock IP address from CSF Firewall at command line you need to execute below mentioned commands.

Login into the server via shell access and go to the path of CSF firewall.

/etc/csf

Edit the file csf.deny.

vi csf.deny

Remove the IP address from the list and save the file.

Once the IP address removed we need to restart the Firewall.

To Restart Firewall one need to execute below mentioned command.

csf -r

Install or upgrade the csf webmin module and csf Uninstallation.

To install or upgrade the csf webmin module:

Install csf first.

wget http://www.configserver.com/free/csf.tgz
tar -xzf csf.tgz
cd csf
sh install.sh

Install the csf webmin module in.

Webmin > Webmin Configuration > Webmin Modules >
From local file > /etc/csf/csfwebmin.tgz > Install Module

Uninstallation

Removing csf and lfd is even more simple:

On cPanel servers:

cd /etc/csf
sh uninstall.sh

On DirectAdmin servers:

cd /etc/csf
sh uninstall.directadmin.sh

On generic linux servers:

cd /etc/csf
sh uninstall.generic.sh

How to install CSF Firewall on your Server.

Installation

Installation is quite straightforward:

rm -fv csf.tgz
wget http://www.configserver.com/free/csf.tgz
tar -xzf csf.tgz
cd csf
sh install.sh

Next, test whether you have the required iptables modules:

perl /etc/csf/csftest.pl

Don’t worry if you cannot run all the features, so long as the script doesn’t report any FATAL errors

You should not run any other iptables firewall configuration script. For example, if you previously used APF+BFD you can remove the combination (which you will need to do if you have them installed otherwise they will conflict horribly):

sh /etc/csf/remove_apf_bfd.sh

That’s it. You can then configure csf and lfd by edit the files directly in /etc/csf/*, or on cPanel servers use the WHM UI

csf installation for cPanel is preconfigured to work on a cPanel server with all the standard cPanel ports open.

csf installation for DirectAdmin is preconfigured to work on a DirectAdmin server with all the standard DirectAdmin ports open.

csf auto-configures your SSH port on installation where it’s running on a non-standard port.

csf auto-whitelists your connected IP address where possible on installation.

You should ensure that kernel logging daemon (klogd) is enabled. Typically, VPS servers have this disabled and you should check /etc/init.d/syslog and make sure that any klogd lines are not commented out. If you change the file, remember to restart syslog.
