Managing a Linux server, the most common and universal way to access it is directly from the command line console. If you do not have physical access to the server, as many system administrators do not these days, you will probably use a tool like SSH. Linux servers do not normally come with graphical interfaces, […]

Monitoring your dedicated server is a good way to prevent attacks, crashes, and other problems that invariably creep up. Although there are many external tools to help you monitor your server, Linux-powered servers also have plenty of internal tools that can help you with both monitoring and troubleshooting.
Netstat is a small network tool that can […]
When you login to your dedicated server via SSH, there are normally two options: your own username and root. It is inadvisable to login directly as root, but you can always use “su” or “sudo” to run root commands. In some circumstances, however, it may actually be more convenient and useful to login as another […]
With the emergence of dynamic websites, most sites on your dedicated server probably use some form of database. Chances are, if a site uses a database, it is running on MySQL or other SQL server. It is no longer sufficient for system administrators or even individual website owners to only backup the contents of a […]
Apache HTTP Server is by far the most widely-used web server on the Internet. Chances are, your Linux or Unix-like dedicated server runs it to serve up websites to the public. Doing this uses bandwidth, and there is no way to get around it in principle, but you can take some steps to minimize the […]
Linux servers and many other servers with Unix-like operating systems rely on archiving and compression tools like tar and gzip to rotate logs, store backups, and even cache websites. In those cases, dedicated server’s software will automatically make use of those tools. If, however, you ever need to extract data from those archives or make […]
Optimizing your MySQL database can help it run better, reduce fragmentation, and ultimately give you a boost in performance. In many cases, you can optimize your MySQL database using a graphical frontend, such as phpMyAdmin, but in some instances it is quicker and easier to run the command from within an SSH session, especially if […]
Debian GNU/Linux and other OSes based on the free and open source operating system, such as Ubuntu, use a package management system called APT to install, update, and remove software. APT is very powerful and easy to use. You can access it from the command line via SSH, giving you full control over the software […]
Many times, managing your dedicated server from the command line can be tedious, especially when there are web-based control panels that make a lot of administrative tasks easier.
Control panels are great, and some proprietary panels like cPanel and Plesk have become commonplace on servers all over the world. The benefits aside, however, you should also […]
ModSecurity is an application firewall that protects your server from script exploits found in web applications. It is a great tool you can use to tighten security and adds another layer of protection in addition to your network firewall. This is a brief guide that should help you get ModSecurity installed on a dedicated server […]

1. Have a plan – It sounds very basic, but I can attest from experience that not having a clear vision can cause you big headaches in […]
Security is critical for any server that will connect to the Internet. Once your server is out there, you will get attackers trying to compromise its integrity. The question is not whether or not you will be attack but whether or not you were prepared to defend against it.
The best way to prevent attacks from […]
There has been much debate on the server level about Windows vs Unix, Unix vs Linux, BSD vs Linux, Windows vs Solaris, and just about any other matchup you can imagine. Choosing the right one is not as easy the supporters of each OS make it seem. You have to consider many factors when choosing […]
Once you have made the decision to move to a dedicated server, you may wonder, “What now?”. There is a lot to do when you first get started, and not all of the necessary tasks may be immediately apparent. What follows is a brief checklist that may help in those first hours with your new […]
If you spend any time on free software websites or forums, you have undoubtedly heard both sides of the argument of Linux vs. BSD. Each side claims to have advantages in particular areas, so it may be difficult for you to easily tell which one is actually better. Before you even begin to decide which […]
When you are in the market for a dedicated server, it is important to make sure you get the most for your money. Whether you are buying the server or leasing it, you do not want to end up with a machine and service that is less than what you expected. Since needs vary, I […]
Most hosting providers offer reseller plans that range from simple referral programs to complete unmanaged dedicated servers. But just because such plans exist does not mean you can get rich just reselling hosting. Is it possible at all? How much work should you expect to endure to make a serious business out of it? These […]
Many web hosting providers, perhaps even most, use CentOS to power their dedicated servers. Of the many options for paid operating systems (such as Red Hat Enterprise Linux or even Windows) or free operating systems (such as Debian or Slackware), these hosts choose CentOS. The question is “Why?” What is so special about this Linux […]
There are many files on your dedicated server that can give you valuable information about the current running condition, errors, or general status. Files like those in the /proc directory, for example, can provide you with vital system information. Nevertheless, it is not a good idea to just open files like that in a text […]
In most cases, your password is the only thing standing between your server and all of its treasures, and the horde of violent hackers waiting to rip it to pieces. Your password is your safeguard. Without it, you have no access, and if it falls into the wrong hands, you are deep trouble.
There are several […]
When you transfer files from your computer to your server or from one computer to another, you probably use an FTP program. Some of those programs, like FileZilla, offer support for additional protocols like SFTP. There is an important difference between FTP and SFTP, and you should know what both are before you start transferring […]
Many web hosting companies offer “unlimited” packages. These are hosting deals that include one or more features in an unlimited quantity. Some of them include unlimited disk space or storage, unlimited bandwidth, unlimited email accounts, unlimited domains, and unlimited databases.
While such a deal sounds appealing, it is important to read the terms of service and […]
While web-based control panels are good for some tasks, bulk file management is not one of them. It is quite a bit slower to have to navigate through various directories, especially if you have a good size dedicated server with many domains attached to it. Using a web-based file manager can be downright painful. Fortunately, […]
