How to Install CSF On Ubuntu

 

 

 

 

The CSF(ConfigServer Firewall) firewall program is a powerful tool that enhances the security of your Linux system. Additionally, it has a Login Failure Daemon (LFD) that monitors your server for failed login attempts as well as performing actions on culprit IP addresses.

 

 

 

 

 

In this article, we will explain How to Install CSF On Ubuntu and protect the server.

 

 

 

 

 

Step 1: Getting your system up and running

 

 

 

 

  1. Sign in to your system or register a newly created one by logging in to your VPSie account
  2. Connect by SSH using the credentials we emailed you.
  3. Once you have logged into your Ubuntu instance, run these commands to update your system.
apt-get update && apt-get upgrade -y

 

 

 

We need to do is to make sure CSF isn’t installed. This can be done by running a status check; run the following command:

 

 

 

# /etc/init.d/csf status

 

 

 

 

 

 

Step 2: Install CSF

 

 

 

 

 

It’s time to download the package using the following command:

 

 

 

wget http://download.configserver.com/csf.tgz

 

 

 

Then unpack the files with the following command:

 

 

tar -xzf csf.tgz

 

 

 

 

 

Step 4: Install via the Script

 

 

 

 

 

After unpacking, switch to the newly created directory:

 

 

cd csf

 

 

 

Run the installer,

 

 

 

sh install.sh

 

 

 

You will then see “Installation Complete” as confirmation.

 

 

 

 

 


Step 4: Test the Installation

 

 





Run the following command to test the installation,



perl /usr/local/csf/bin/csftest.pl



OUTPUT


# perl /usr/local/csf/bin/csftest.pl
Testing ip_tables/iptable_filter...OK
Testing ipt_LOG...OK
Testing ipt_multiport/xt_multiport...OK
Testing ipt_REJECT...OK
Testing ipt_state/xt_state...OK
Testing ipt_limit/xt_limit...OK
Testing ipt_recent...OK
Testing xt_connlimit...OK
Testing ipt_owner/xt_owner...OK
Testing iptable_nat/ipt_REDIRECT...OK
Testing iptable_nat/ipt_DNAT...OK

RESULT: csf should function on this server
