Having access to man pages on your server is a pretty essential asset to be familiar with. If you’re not familiar with man pages they are documentation provided with software packages on Unix systems. They provide a sort of manual for applications, services and system resources. You can learn more about man pages in our introductory article. By default on Ubuntu based servers this command is not provided, since it’s a great tool to have access to this article will help you get them setup.

On an Ubuntu server the default firewall management command is iptables. While iptables provides powerful functionality it’s syntax is often seen as complex. For most users a friendlier syntax can make managing your firewall much easier.

Introduction

Git is an open source, distributed version control system (VCS). It’s commonly used for source code management (SCM), with sites like GitHub offering a social coding experience, and popular projects such as Perl, Ruby on Rails, and the Linux kernel using it.

Memcached is a distributed, high-performance, in-memory caching system that is primarily used to speed up sites that make heavy use of databases. It can, however, be used to store objects of any kind. Nearly every popular CMS has a plugin or module to take advantage of Memcached, and many programming languages have a Memcached library, including PHP, Perl, Ruby, and Python. Memcached runs in memory and is thus quite speedy since it does not need to write data to disk.

FTP (File Transfer Protocol) is likely the most well-known method of uploading files to a server; a wide array of FTP servers, such as vsftpd, and clients exist for every platform.

PostgreSQL supports multiple client authentication methods including: trust, reject, md5, password, gss, sspi, krb5, ident, peer, ldap, radius, cert, and pam. Here we’re only going to concern ourselves with two: ident and md5.

When connecting to PostgreSQL on Linux for the first time many admins have questions, especially if those admins are from the MySQL world. By default, when PostgreSQL is installed, a postgres user is also added.

nginx is a free, open-source, high-performance web server. Need HTTP and HTTPS but don’t want to run Apache? Then nginx may be your next go-to, at least for Linux.
