Introduction

Just as regular visitors reach our server every day, so do others with more nefarious intentions. It is simply not reasonable to run an online service without some layer of protection. To protect against some of these attacks, Ubuntu ships with ufw (Uncomplicated Firewall). This is a tool designed to make Ubuntu firewall management as easy and user-friendly as possible. Specifically, ufw provides a cleaner interface for the core firewall tools netfilter and iptables, which, while robust, can be challenging to master.

By default, Plesk typically stores backups on the server. This can, however, present a risk if the hard drive or RAID fails on the server. If this ever occurs, you can possibly lose both data and your backups. To avoid this situation, Liquid Web recommends storing additional backups in a remote storage location.

What is 2FA

Two-Factor Authentication (or 2FA as it often referred to) is an extra layer of security that is used to provide users an additional level of protection when securing access to an account. 

What Is the Liquid Web CLI Interface?

This is the official command-line interface for the Liquid Web API. CLI stands for the “command-line interface” which is used for interacting with multiple Liquid Web services via the Liquid Web’s Public API.  

What is Bash?

Bash, or the Bourne Again SHell, is based on the Bourne shell. It is the default shell command language interpreter for GNU Linux/Unix and is accessed via a terminal. The shell was the original method for interacting with the operating system before GUIs were implemented. It has the ability to execute single commands, understand regular expressions, as well as scripts written in the bash language. It is currently the default interactive shell on most all modern Linux distributions.

What is Chocolatey?

Chocolatey or Choco as it is sometimes referred to, is a free, open-source package manager for Windows that is very similar to Apt or DNF in the Linux realm. In other words, this is a program used for installing software via the Windows command line. It downloads a program, installs it, then it will check for updates, and installs those updates automatically if needed. Those who use Linux are quite familiar with the package management systems like this.

What is Screen?

Screen is a terminal program in Linux which allows us to use a virtual (VT100 terminal) as full-screen window manager which multiplexes an open physical terminal between multiple processes, which are typically, interactive shells. It allows us to access multiple terminal sessions within a single terminal or a remote terminal session. It is most useful when addressing multiple Linux shell commands on the command line, as well as separating commands from the shell that started the commands.

What is ApacheTop?

ApacheTop is an uncomplicated command line (CLI) utility that is used to monitor http traffic in real-time. It achieves this task by analyzing the incoming apache logs and based on that data presents understandable output to our screen. It can be configured to output X number of hits, or output X number of hits within X seconds.

In this article, we will be discussing the various methods and techniques used to locate and uninstall the software from a Ubuntu/Debian based server. We will primarily be using the apt and dpkg commands on the command line.

In this article, we will be reviewing the Apache Service Status. Sometimes checking the performance of a Cloud Dedicated server can be difficult. Apache has built-in utilities that assist in monitoring the usage and performance of Apache. Apache Status also provides information that aids in performance auditing and control tuning.
