Before we get started with the installation, let’s find out what Samba is and how we can utilize it. Samba is a free and open-source software that allows files to be shared across Windows and Linux systems simply and easily. To be exact, it is an open-source implementation of the SMB/CIFS protocol.

/etc/csf/csf.conf to continue using the MaxMind databases
Recently MaxMind, the company that provides the IP lookup database based on country of origin for CSF, has decided to require a free license to be able to access that database now. They had to do this, so they can conform to the new state law in California for the CCPA act.
When your company hosts a website or web app online, whether it’s an individual dedicated server or a whole server cluster, you naturally expect to have uninterrupted access at all times. However, it’s possible that in rare circumstances, your server could accidentally block your IP and prevent you from connecting and using the service.
If that has happened to you, this quick summary will provide you with all the essential information needed to verify the status of your IP. Additionally, we will offer some of the most common reasons for being blocked, as well as a few suggestions on how to unblock and whitelist your IP as quickly as possible.
In this article, we will provide an in-depth explanation of how to set up and customize the messenger feature in CSF on an unmanaged or core managed server. Let’s begin by defining exactly what CSF or ConfigServer Firewall is and what it does.
Broadly speaking, a firewall is part of a network or server that is designed to restrict potentially malicious and unauthorized access to the hardware while still allowing outward communication from the network or server. There are two types of firewalls; physical hardware firewalls which are devices that connect to the destination server and stop traffic from passing to it and, software-based firewalls that run on a server and filter/reject connection attempts. In both cases, the firewall is at its core, a security measure meant to protect your data from unauthorized access. Today, we are going to review how to install CSF Firewall on a Ubuntu server Continue reading “How to Install ConfigServer Firewall (CSF) on Ubuntu”→

In this manner, customers can remove blocks on their IP addresses even when they are unable to access WebHost Manager itself due to the block.

Reading Time: 5minutesDenial of Service (DoS) and Distributed Denial of Service (DDoS) attacks are common threats that every publicly accessible web server faces. The purpose of such attacks, in the simplest terms, is to flood a server with connections, overloading it and preventing from accepting legitimate traffic.
Attacks increasingly have become automated instead of directly targeted and botnets (networks of infected computers that can be remotely controlled) continue to grow at a rapid pace, making DoS and DDoS attacks much more common.
Fortunately, CSF can be used to help mitigate small attacks. Continue reading “Basic DoS/DDoS Mitigation with the CSF Firewall”→
Reading Time: 4minutesIn addition to being able to manage traffic from a specific country or a list of countries, CSF allows you to manage access by country to specific ports. This can be useful if you need to ensure that a particular service is available globally (such as your web server on port 80) but want to restrict international access to services such as WHM/cPanel, SSH, or FTP.
