Some of you might have experienced slow response times from your server, which cause the website to take a long time to load. In cPanel servers, Apache is the default webserver used, both for static and dynamic pages. Now let me tell you how you can speed things up with Nginx.
Have you ever wondered as to where all your server memory is getting used up? Have you noticed growing web-server processes and wondered if the process is actually using up all the memory?
Do you want to find how much memory is used exclusively by a process? The simple “ps” command can get you the memory details per process, but Read the rest of this entry »
Imagine a server than keeps crashing every other day. For most webhosts’ this isn’t something too hard to imagine. Every host would have gone through this phase, where they are clueless as to why their server keeps going down.
Most of the time, the blame falls on faulty hardware. Usually this is true, circumstantial evidence proving that no recent changes were made to the software, and hence the source of issue would most likely be hardware. This doesn’t always have to be correct, as there are other things that could go wrong.

Linux has always been blessed. As we have a large number of people working for the betterment of the product, we’ll have bug fixes/security updates every now and then. This has got 2 sides.
So, we’ve got to update the systems as and when the updates arrive. But, an update once in a month will mean a reboot once a month, which will mean monthly server downtime. This is where Ksplice comes into the picture.
Apache is one of the most popular web servers of all time. A visit to Netcraft shows that Apache (with more than 54% of the total usage) is still the uncrowned king of web servers. Among a very long list of features, the best are extensibility and reliability. But on a low spec server running Apache 1.x, a large amount of traffic can quickly bring the server to its knees. For each new connection from a client, Apache creates a new process. Thus for a large number of connections, resource consumption is high. In worst cases, the resource consumption is so high it overloads the server and causes it to crash!! and so does your reputation as a Webhost! That is why it is important to be aware of alternatives and how they can sometimes even be used to support your existing web servers.

How many times have you thought of purchasing a proprietary Control Panel to help you with day to day administration? If you already have one, wouldn’t it be nice if your time was spent more on configuring/securing core services of your server; rather than fixing features/functionalities of the panel!

Linux is a premium force in the web hosting industry, which is also achieving popularity as a PC operating system nowadays. When it comes to hosting a website, Linux web servers are primarily chosen due to their flexibility, stability and security of services. But as we all know, security of all operating systems revolve around controlling access and is hence subject to exploits. Since Linux is open source, vulnerabilities can be easily exploited by potential attackers to gain illegal access to a web server. As a measure of securing Linux at every level, from the kernel up, Security Enhanced Linux (SELinux) was developed.
