Introduction

In this article we will learn what the Network Time Protocol (NTP) is and how to install it on the two Linux distributions most commonly used on Liquid Web’s servers. We will be focusing on using CentOS 7 and Ubuntu 18.04 servers, but the process is largely the same on other recent versions of each. Before we start, make sure we are familiar with using SSH (Secure Shell) as we’ll need it to connect to the server. Here’s a link to one of our articles on the basics of SSH if you are unfamiliar with its usage.

Introduction

SNMP, or Simple Network Management Protocol, is widely used to communicate with and monitor network devices, dedicated servers, and more, all via IP. In this case, we'll be installing an SNMP agent on a CentOS VPS server, which will allow for collection of data from our server, and make the information available to a remote SNMP manager.

This guide will walk you through the steps for setting up a firewall using iptables in an Ubuntu VPS server. We’ll show you some common commands for manipulating the firewall, and teach you how to create your own rules.

What is Webmin?

Webmin is a browser-based graphical interface to help you administrate your Linux server.  Much like cPanel or Plesk, Webmin allows you to set up and manage accounts, Apache, DNS zones, users and configurations.  As these configurations can get somewhat complicated Webmin works to simplify this process. The result is fewer issues during server and domain setup.  Which results in a stable server and a pleasant administration experience. Unlike Plesk or cPanel, Webmin is completely free and open to the public. Unfortunately, here at Liquid Web, we do not offer managed support for Webmin, but we are always willing to assist as much as possible when issues arise.   You can download Webmin from their site. Also, you can find some excellent documentation on this interface.

Nginx is an open source Linux web server that accelerates content while utilizing low resources. Known for its performance and stability Nginx has many other uses such as load balancing, reverse proxy, mail proxy, and HTTP cache. With all these qualities it makes a definite competitor for Apache. To install Nginx follow our straightforward tutorial.

Pre-Flight Check

• These instructions are intended specifically for setting up an email account in Mozilla Thunderbird 38.3.0 on Mac OS X 10.11.1.
• While the steps should be similar across platforms and operating systems, they may not necessarily apply to older versions of Thunderbird.
• For help with general email account settings, see How to Set up Any Email Client.

You can edit an email account that already has been configured in Thunderbird, for example should you decide to switch between non-SSL and SSL settings or change the server’s connection port. You change the connection type between standard (non-SSL) and secure (SSL) by changing the hostname and port for the incoming and outgoing servers.
