Most Linux items that need backing up are stored in user home directories. This usually includes virtual web server directories as well, depending on the web server and settings you are using. One exception to this rule is configuration files. These are stored in /etc and other places. When it comes time to backup, many […]
TTL refers to Time To Live for a DNS server. You may find that your server’s default TTL is quite long, perhaps even 48 hours. This means that any changes to DNS zone files will take up to 48 hours to propagate to users. Because that can be very inconvenient when you want to change […]
If you have been following our Ubuntu server series, you have learned how to setup a LAMP server and configure an APF firewall. In order to do any of this, you likely already had your networking configured correctly, but if you do not, this brief tutorial explain how to setup name servers and ensure they […]
DNS is one of the most important features of your server. It is what connects your server’s true identity, its IP address, to its human-readable name, also known as its domain name. In order to add domains, sub-domains, or mail server addresses, you need to edit DNS zone entries for your domains. Using a web-based […]
Hosting Automation refers to software that makes web hosting as easy as clicking buttons on a graphical interface. For those who have worked with naked Linux or Unix servers, this is a dramatic contrast from the command line interface to which you may be accustomed. Most hosting automation comes in the form of a web-based […]
Choosing your operating system and web server software is only the beginning. If you need a custom dedicated server built to your specifications, you will need to specify several other types of software, including database system, DNS, mail transfer agent (MTA), scripting languages (PHP, Ruby, Perl, etc.), firewall, virtualization, and more.
DNS – The management of […]
Linux-based dedicated servers typically run two primary types of programs: those which require user interaction and those which perform tasks in the background without user intervention. Those programs that run in the background are commonly called “services” or “daemons”.
Servers usually require numerous services to run the background, such as the web server, mail server, database […]
Time To Live is a term that refers to the amount of time that passes before a DNS zone is updated. If you are running your own DNS on your dedicated server, you may want to consider your TTL setting and how it affects your websites.
The old standard TTL setting for most DNS servers was […]
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 […]
One frequently overlooked component of dedicated server management is domain configuration and optimization. A server that has no domains and no DNS is only known by its IP addresses. Realistically, this makes domains a necessity. More than likely, you have at least two domains, and if you are hosting other websites, you may have several. […]
DNS, which stands for Domain Name System is one of the most important components of a dedicated server. In fact, DNS is so important that the Internet itself would not function without it. If your dedicated server lacks DNS, no one but you will be able to reach it. The question up […]
When many people think of proxies, they often imagine public school Internet filters or the tools people use to circumvent them. There are, however, numerous other uses for proxies, especially for dedicated servers.
A proxy is basically a network layer that sits between the computer and the Internet. All traffic passes through the proxy, […]
When you setup a new dedicated server, nameservers are some of the most important components. Without nameservers, your server’s websites cannot connect to the outside world. Any type of nameserver errors should be addressed immediately. The following error is a common one:
WARNING: Not all of your nameservers are in different subnets
If you […]
No matter what precautions you take or how many hours, days, or even weeks you have spent hardening your server’s security, the possibility of being accused of sending spam still exists. This can cause you all kinds of problems, from the inability to send mail to certain Internet Service Providers (ISP), to having your […]
A service or daemon is a memory-resident program that runs in the background. Your operating system will typically start it at boot (although not always) and continue to run it without any intervention on your part. Some common services usually running on a Linux dedicated server are: web server (such as Apache), database […]
DNS or Domain Name System gives the Internet its identity. Every website URL and email address is linked to an IP address, and DNS is the system that translates the IP into a domain.
When you setup DNS zone records on your server, there are various types you will encounter:
A – An A record is […]
