The time on your dedicated server might not be something you think about every day, but it is vitally important to keeping every piece of your server running in sync. Since it is so crucial, a lot of effort has been made by Linux developers to make it run smoothly without much effort. However, there are a few things you are going to be able to want to do with time on your server.

Now that you have seen the basics of exigrep, let us dive into some e-mail troubleshooting where exigrep really shines.

Domain Name Service, or DNS, can be one of the most be one of the more complicated concepts in server administration. This article will walk through changing an A record from the Linux command line.
This article assumes that you are running BIND on a linux server, that you already have an understanding of what DNS is, the different types of DNS entries, and how DNS works. Please note: The incorrect editing of your zone file can take your site offline. All editing must be done on the authoritative nameservers for the given domain.

Perhaps a particular domain on your cPanel server has stopped receiving e-mail. Or, an address on your domain is able to receive e-mail, except from your supplier. Maybe you can receive e-mail just fine, but are receiving error message bounce-backs from Yahoo. How are you going to get the fine-grained information you need to figure out just what is going on?

Domain Name System, or DNS, is a complex system to understand, but cPanel has simplified the administration of DNS by adding it to the WHM interface. One of the most common tasks involved with administrating DNS is updating an A record. A records are one of the most common DNS entries, and cPanel makes updating them easy.

The Apache web server is the most popular web server in the world. This is in part due to its modular design. Apache 2 introduced Multi-Processing Modules, or MPMs. The MPMs change the basic functionality of the web server. They do this by modifying how Apache listens to the network, accepts, and handles requests. A lot of this functionality is rather technical and outside of the purview of this article. This article will briefly explain what the various MPMs are and how they work. For more detailed information on the various MPMs, please visit the Apache Documentation.

The Apache web server is one of the most popular and powerful web servers in the world, due in part to its ease of administration and flexibility. This flexibility comes Apache’s modular design. The modules allow for Apache to perform additional functions, such as natively rewriting URLs to support SSL encryption. This allows administrators to modify Apache to meet their needs; adding modules that are needed and removing ones that are not.

‘Premature end of script headers’ can be an extremely vague error that leads to some headaches. Here are some suggestions that might help you fix the problem.

If Apache fails, and will not successfully start again, check the error log. If you see an error similar to the following, it could indicate that your server has run out of semaphores.

A runlevel is one of the modes that a Unix-based, dedicated server or a VPS server OS will run on. Each runlevel has a certain number of services stopped or started, giving the user control over the behavior of the machine. Conventionally, seven runlevels exist, numbered from zero to six.
