Linux machines are  aware in the case of security. This extra security may sometimes become a headache for simple linux users.

For example, if u have separate partitions or hard drives , every time you have to mount those when required.The time-saving solution is to mount such media permanently.

Firstly to tell Debian where to find the mount and where you want it mounted. Secondly, to create the folder within Debian’s recognised file structure to house the mounted media. After you perform this configuration, your backup folder on a secondary disk can be accessed from within your /home/user folder.

1. Open the fstab file that controls your mounts:

nano etc/fstab

2.Find out the name of partition that you are planning to mount . It lists recognized partition tables:

fdisk -l

In this article you are going to learn how to install Postfix on your already running Debian 5.0.

I am going to assume you have it networked and have a domain registered that you want to use. At the end of this article you should have a working mail server, ready for use:

Installation:

apt-get install postfix

Configuration:

The file for confugure is /etc/postfix/main.cf.

To set your Postfix installation up for your domain you will want to open that file for editing like so:

nano /etc/postfix/main.cf

The above command opens main.cf in the Nano editor. What you need to look for is this section:

There is a better, quicker way to do this which is to clone your entire drive onto a new drive.

You can do this with a tool like GParted, but there is also a command line tool that will get the job done as well. This tool is ddrescue. Now with ddrescue you will have to have your new disc partitioned (it will not partition for you). In this article I am going to show you how to get your dying Linux drive cloned onto a new drive.

Installation of ddrescue:

apt-get install ddrescue gparted

Paritioning your new drive:

After you installed the new drive reboot your server. Then do the following:

  1. Start GParted.
  2. Create a partition scheme on the new drive  identical with the old drive.
  3. Save the new partition scheme and you are ready to clone.

What’s not always appreciated, is just how significant a portion of the market Linux servers are getting to be.
Whereas unit shipments of Windows servers increased 28.2 percent year over year in the second quarter of 2010, Linux server revenue grew 30.0 percent to $1.8 billion when compared with the second quarter of 2009.
Linux servers now represent 16.8 percent of all server revenue, up 2.5 points over 2009.

Linux is eminently better suited to server use than Windows. Why ? Let’s see:

1. Stability

Linux systems are well known for their ability to run for years without failure; in fact, many Linux users have never seen a crash. That’s great for users of every kind, but it’s particularly valuable for small and medium-sized businesses, for which downtime can have disastrous consequences.

Linux also handles a large number of processes running at once much better than Windows does–that’s something, in fact, that tends to degrade Windows’ stability quickly.

Then there’s the need for rebooting. Whereas in Windows configuration changes typically require a reboot–causing inevitable downtime–there’s generally no need to restart Linux. Almost all Linux configuration changes can be done while the system is running and without affecting unrelated services.

Similarly, whereas Windows servers must often be defragmented frequently, that’s all but eliminated on Linux. Let your competitors endure the plentiful downtime that inevitably goes hand-in-hand with Windows; trusty Linux will keep you up and running and serving your customers around the clock.

G-WAN – Fastest Webserver Ever

Valic —  August 24, 2010 — 1 Comment

G-WAN is using full ANSI C scripts and is a FREE Web App. server.

G-WAN redefined the static Web content hierarchy on  Linux. Now, G-WAN redefines the standards of dynamic Web content generation.

On a gigabit LAN, ApacheBench compared G-WAN , IBM Apache+PHP, SUN GlassFish+Java and Microsoft IIS+C#.

Result, G-WAN does the job with 5 million times less servers. See images below:
