Hello,

ImageMagick is a software used  to create, edit, and compose bitmap images. Using ImageMagick we can read, convert and write images in a variety of formats including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF. ImageMagick is used to translate, flip, mirror, rotate, scale, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.

ImageMagick is typically utilized from the command line or you can use the features from programs written in your favorite programming language. Choose from these interfaces: G2F (Ada), MagickCore (C), MagickWand (C)

How to install ImageMagick On Linux server:

wget ftp://ftp.imagemagick.org/pub/ImageMagick/ImageMagick.tar.gz

tar -zxvf ImageMagick*.tar.gz
cd ImageMagick*

./configure

make

make install

You can verify the installation with command :

Hello,

For taking backup of you database you have to make sure that you database is good enough. with shell access you can take the database backup in .sql format with following command

#mysqldump user_databasename > database.sql

As you are having database backup and want to restore it then use following command

#mysql user_databasename < database.sql

How to install and configure the CSF (configserver) firewall.

CSF can be used on a wide range of Linux systems, including those running cPanel. Following are the steps to install and configure the CSF.

Installation is quite straightforward:

rm -fv csf.tgz

wget http://www.configserver.com/free/csf.tgz
tar -xzf csf.tgz
cd csf
sh install.sh

If you would like to disable APF+BFD (which you will need to do if you have
them installed otherwise they will conflict horribly):

sh disable_apf_bfd.sh

That’s it. You can then configure csf and lfd in WHM, or edit the files
directly in /etc/csf/*

csf is preconfigured to work on a cPanel server with all the standard cPanel
ports open. It also auto-configures your SSH port if it’s non-standard on
installation.

To configure CSF modify the config files in /etc/csf/ - or if you are running WHM you can modify the CSF settings in WHM itself.

You should ensure that kernel logging daemon (klogd) is enabled. Typically, VPS
servers have this disabled and you should check /etc/init.d/syslog and make
sure that any klogd lines are not commented out. If you change the file,
remember to restart syslog.

See the readme.txt file for more information.

Uninstallation
==============
Removing csf and lfd is even more simple:

cd /etc/csf
sh uninstall.sh

For installing the SSL certificate you need to have a dedicated IP Address, and make sure that your domain is registred domain name and resolving perfectly

Step 1: You need to generate CSR (certificate signing request ) from your webhost nameger. which required following information.

———————————–
- Host to make cert for:
- Country(2 letter Abbreviation):
- State:
- City:
- Company Name:
- Company Division:
- Email:
- Password:
———————————–
Also please create webmaster@yourdomain.com (replace yourdomain.com with the domain that you want the SSL certificate to be setup for) and provide us with its password so we can complete the installation process.

After CSR generation you will get the CSR and RSA key

step 2: With the help of RSA key you need to purchase SSL certificate from any of SSL provider such as COMODO ,instant SSL

step 3: Once you got the SSL cerificate then you need to provide that certificate to hosting provider so the hosting provider will install SSL cerificate from WHM >> SSL/TLS >> Install a SSL Certificate and Setup the Domain option.

Note: Please don’t disable the Windows Firewall unless and until you have the other appropriate firewall software installed on your system

There are mainly three methods for disabling the Windows Firewall. The first method is for any user with administrative privileges on an individual machine not remotely or collectively managed in any way. The other two methods are for use windows Administrators on fully managed systems or windows servers.

1) Using the Control Panel

This method is for any user with administrative access to unmanaged systems

1. From the Start menu, select Control Panel, then select Windows Firewall.
2. Select Off, then click Ok.

2) Using Local Policy

This method is for administrators with administrative access to unmanaged systems or locally managed systems where the machine is not part of a Windows 2000 or higher domain.

Go to Start menu >> select Run, here enter gpedit.msc.
Expand the Computer Configuration folder, then the Administrative Templates folder.
Expand the Network folder, then the Network Connections folder, then the Windows Firewall folder.
Select the Standard Profile folder.
Double-click the Windows Firewall: Protect all network connections option.
Select Disabled, then click OK.
Select the Domain Profile folder.
Double-click the Windows Firewall: Protect all network connections option.
Select Disabled, then click OK.
Close the Group Policy dialog box.

3) Using Group Policy

This method is for administrators with administrative access to managed machines that are part of a Windows 2000 or 2003 Active Directory domain.

Create a new Group Policy object, and give the object a descriptive name (for example, ITS-Turn off Windows Firewall).
Select the newly created group policy.
Right-click on the newly created policy and select Edit.
Expand the Computer Configuration folder, then the Administrative Templates folder.
Expand the Network folder, then the Network Connections folder, then the Windows Firewall folder.
Select the Standard Profile folder.
Double-click the Windows Firewall: Protect all network connections option.
Select Disabled, then click OK.
Select the Domain Profile folder.
Double-click the Windows Firewall: Protect all network connections option.
Select Disabled, then click OK.
Close the Group Policy dialog box.
In the Security Filter section, click Add.
Search for the objects that this group policy will be applied to, then click OK.
Close the Group Policy editor.

For few reasons it becomes necessary to change IP address on your linux Server. You need to change your IP address if you are changing your Host, getting dedicated IP or anything alike.

Following instruction will help you to change IP address.

Login to your server (preferably via console or SSH) and switch to the root user
Open network configuration file and update it accordingly.
#root: vi /etc/sysconfig/network-scripts/ifcfg-eth0
Press “i” ( for insert ) and change the file once updated press ESC and save setting with (:w) also you have to change the host name and the default gateway of the machine.
For this you have to edit one more file
#root: vi /etc/sysconfig/network modify the configuration by using the “i” ( insert ) to change your new hostname and gateway information. After completion hit “ ESC ” and save setting using (:w )

Reboot machine using : #root : reboot or restart network by #root: service network restart.

You can now see the new IP address and host name that you had assigned.

Today most of the sites are based on CSS. There are many reasons why CSS have become so popular some of them are easy maintenance of website, clean html code, easy updates, increase download speed, reduce bandwidth and most important improves search ranking ;
You must be wondering how it helps in ranking? Here’s the explanation….

Generally a page of site get index when the spider/bot of search engines crawls content of that page, When a search engine, such as Google, sends a spider to crawl your website, it looks through the code of your webpage they actually read certain elements of your HTML code. Certain HTML code holds more weight than other tags. So it is necessary to have a clean and readable code which is easy to understand by spiders, if there are unnecessary text and tags in your HTML file, spiders will have to struggle to understand that page is related to a particular search keyword. Using CSS you will be able to change the code layout without destroying the actual visual layout and will get an clean html code which will result to better search engine rankings.
eg .

You can easily make the main content of your site to show up above the header or navigation menu in the code of your website; thus will help to show search engine crawlers the importance of your content.

Today major search engines such as: Google, Yahoo and MSN loves to see your content; the text, not the clumsy code. Using CSS you can have pure and clean food for spiders.

You normally switch between shells to gain extra functionality; each shell is having it’s own flavor; so if you do decide to change your shell you must be very careful otherwise it may cause you a lot of hassle.

Before switching to new shell please check if it is present in /etc/shells, if this file does not exist, get it added by your administrator with required shell script.

A normal user may only change the login shell for her own account, the super user i.e. root user may change the login shell for any account.

For changing your shell you use a command “ chsh ” which will change your shell.

Syntax ;

chsh -s {shell-name} {user-name}
here -s {shell-name} : Specify your login shell name (full path of the shell you want to use )
{user-name} : It is optional, useful if you are a root user.

You will have to provide password when prompted and your shell will get changed. Remember you new shell will get activated next time you log in. Executing the chsh command will not change the shell you are currently running.

eg ;

*) You have root access and you want to change the shell of user kim to /usr/bin/ksh,
you will fire the command as ;
chsh /usr/bin/ksh kim.

What is Web-Based Email ?

Web-Based Email is an Internet-based email system that lets you send and receive
email messages from a Web browser. All you need to use Web-Based Email is an Internet
connection and the Internet Explorer Web browser (Internet Explorer v5.5 or later).
How do I access my Web-Based Email account ?
You can log on to your Web-Based Email account from your Web browser by going
to the Web address for your account. The Web address is the same as your domain
name, except you replace “www” with “email”. For example, if your Web address
is “www.example.com”, your email address is “email.example.com”.

The event logs contain the most important information for diagnosing application and operating system failures, determining the health and status of a system and verifying that system and applications are operating properly.

Windows systems store all logs in binary .Evt files and there are three basic event logs: Application (AppEvent.Evt), System (SysEvent.Evt), and Security (SecEvent.Evt). Windows 2000 (and later) servers may contain additional event logs: DNS Server (DNSEvent.Evt), File Replication Service (NtFrs.Evt), and on Active Directory domain controllers, Directory Service (NTDS.Evt).

System log tracks miscellaneous system events like startup, shutdown and events like hardware and controller failures. The Application log is an important source for application status information. When properly integrated with the Windows operating system, applications can report their errors to the Event log by recording an event entry into the Application log. Security log tracks events such as logon, logoff, changes to access rights, and system startup and shutdown.

Windows event logs can be useful for ;

-Securing your network from internal attacks

-Monitoring availability of your critical applications

-Centralized eventlog management integrated with your network monitoring software
