Unblocking attachments in Microsoft Outlook

Filed under Desktop, howto, Microsoft Windows, Software, System, Windows 7, Windows Vista by on April 23, 2009 at 6:42 am {one comment}

To provide enhanced security, Microsoft Office Outlook is designed to prevent you from unblocking attachments. But some time it becomes headache for you. Some times you don’t require this feature. There are two levels of securities in Microsoft Office Outlook Level1 and Level2. Access to Level 1 files is blocked and can’t be changed. When you receive an attachment with a Level 2 file type, you will be prompted to save the file to your hard disk. If you use Microsoft Exchange Server, your system administrator can add and remove file types for both levels of e-mail security.

Level 1

Level 2

There are no Level 2 files by default. If you use Microsoft Exchange Server, your system administrator may add and remove Level 2 file types, or allow you to reduce a Level 1 file to Level 2.

But what if you are not having Microsoft Exchange Server. Following is the resgistry trick which disable the Level1 security feature.

Start > run > regedit

HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Security

(Go to HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Security for Outlook 2003 and HKEY_CURRENT_USER\Software\Microsoft\Office\10.0\Outlook\Security for Outlook 2002. )

Add a new string value called “Level1Remove”.

Make its value a list of allowed file extensions separated by semicolons.

For example, “.shs;.exe” allows access to Shell Scrap Object File and executables.

NVU web authoring system for creating web pages

Filed under CentOS, Desktop, Fedora, howto, Linux, Microsoft Windows, Multimedia, Software, System, Ubuntu, Windows 7, Windows Vista, Windows XP by on April 21, 2009 at 6:11 pm {no comments}

I was trying to build a basic website for my personal use. For a while I used windows notepad for creating webpages. But u must have a very good html knowledge for that. While searching an open source solution for it I come to know NVUweb authering system.

Nvu (pronounced “N-view,” for a “new view”) is a free, open source software program that allows you to build websites and web pages using a simple WYSIWYG editor (what-you-see-is-what-you-get). Nvu makes creating web pages as easy as using a word processor and rivals such programs as Adobe’s Dreamweaver and Microsoft’s Expression Web, only for free! With Nvu’s built-in site manager, connecting to your website and making changes is a snap.

I liked the software cause you can use the same software in Windows as well as in Linux. I am using it on my CentOS

You can download it from the below link

For windows users:
nvu-1.0-win32-installer-full.exe

For linux user:
RPM base
kompozer-0.7.10-i386.rpm

Source file
kompozer-0.7.10-gcc4.0.3-i486.tar.gz

For more information you can go to their website:

Installing Joomla on CentOS

Filed under CentOS, howto, Linux, Server, Software, System by on April 12, 2009 at 8:02 am {11 comments}

UPDATE:

You can follow the same method for installing Joomla 1.6.0 on CentOS

Joomla! is a free open source content management system for publishing content on the World Wide Web and intranets as well as a Model–view–controller (MVC) Web Application Development framework. The system includes features such as page caching to improve performance, RSS feeds, printable versions of pages, news flashes, blogs, polls, website searching, and language internationalization. Joomla is licensed under the GPL, and is the result of a fork of Mambo.

It is written in the PHP programming language and uses the MySQL database. Here is the step by step guide of how to install joomla on CentOS.

Operating System
CentOS5.2

Joomla
Joomla v.1.5.10

Installing prerequisites:

Enabling RPM repositeries:

rpm -ivh http://apt.sw.be/redhat/el5/en/i386/RPMS.dag/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

Enabling Utter Ramblings repositeries:

rpm --import http://www.jasonlitka.com/media/RPM-GPG-KEY-jlitka

Creating repo file:

touch /etc/yum.repos.d/utterramblings.repo
echo '[utterramblings]' >> /etc/yum.repos.d/utterramblings.repo
echo "name=Jason’s Utter Ramblings Repo" >> /etc/yum.repos.d/utterramblings.repo
echo 'baseurl=http://www.jasonlitka.com/media/EL$releasever/$basearch/' >> /etc/yum.repos.d/utterramblings.repo
echo 'enabled=1' >> /etc/yum.repos.d/utterramblings.repo
echo 'gpgcheck=1' >> /etc/yum.repos.d/utterramblings.repo
echo 'gpgkey=http://www.jasonlitka.com/media/RPM-GPG-KEY-jlitka' >> /etc/yum.repos.d/utterramblings.repo

Installing required packages:

yum -y install mysql mysql-server mysql-devel httpd php php-mysql

Creating database for joomla:

mysql -u root -p
mysql>create database joomla;
mysql>exit
echo "extension=mysql.so" >> /etc/php.ini

Installation of joomla:

Download and unzip the joomla package in your web root directory. In my case it is /var/www/html

Creating a temporary configuration file
touch /var/www/html/joomla/configuration.php
chmod 777 /var/www/html/joomla/configuration.php

Restart your web server:

service httpd restart

Enter the following url in your browser:

http://your_ip/joomla and follow the webinstallation process. It is quit simple.

Installing Nagios on CentOS

Filed under CentOS, Hardware, howto, Linux, Network, Server, Software, System by on April 7, 2009 at 3:46 pm {no comments}

Nagios is a popular open source computer system and network monitoring software application. It watches hosts and services, alerting users when things go wrong and again when they get better. Nagios was originally designed to run under Linux, but also runs well on other Unix variants. Nagios is free software licensed under the terms of the GNU General Public License version 2 as published by the Free Software Foundation.

Operating System
CentOS5.2

Nagios
Nagios 3.0.6

Installing prerequisites on your CentOS box.

yum install -y httpd gcc glibc glibc-common gd gd-devel php

Downloading & Installing nagios and its plugin:

Creating user

/usr/sbin/groupadd nagcmd
/usr/sbin/usermod -G nagios,nagcmd nagios
/usr/sbin/usermod -G nagios,nagcmd apache

Assigning password for user nagios

passwd nagios

Downloading nagios

cd /usr/local/src/
wget http://ovh.dl.sourceforge.net/sourceforge/nagios/nagios-3.0.6.tar.gz

Create a nagiosadmin account for logging into the Nagios web interface. Remember the password you assign to this account – you’ll need it later.
