Hi Ubuntu Users, you might just install the newly fresh Ubuntu 12.04 or Ubuntu 12.10, but you might not get the connection to internet by using USB modem. You can’t directly connect internet connection by just plugging USB device and setting the internet connection.

So in this blog I will be publishing a very simple technique to connect to the Internet connection by using USB modem.Read Full
Database Management Systems
Database software can be generally organized into three categories: SQL, Xbase, and desktop databases. SQL-based databases are professional-level relational databases whose files are managed by a central database server program. Applications that use the database do not access the files directly. Instead, they send requests to the database server, which then performs the actual access.SQL is the query language used on these industrial strength databases. Both are open source projects freely available for your use.Read Full
GNU Privacy Guard
To protect messages that you send by email, most Linux distributions provide GNU Privacy Guard (GnuPG) encryption and authentication (gnupg.org). GnuPG is the GNU open source software that works much like PGP encryption. It is the OpenPGP encryption and signing tool (OpenPGP is the open source version of PGP). With GnuPG, you can both encrypt your messages and digitally sign them—protecting the message and authenticating that it is from you. Currently, Evolution and KMail both support GnuPG encryption and authentication, along with Thunderbird with added GPG extensions.Read Full
In C and C++ programming language Pointers and Arrays are the hearts of developers. But still much of IT professionals are not familiar with the use of Pointers in C. But pointers and arrays are efficient and a powerful programming practice. I will try to elaborate a primary use of pointers with arrays, so getting started.

Disk utility can also be used to create new partitions and prepare them for use. Once a partition has been created, it must be formatted with a file system before it can be used. The standard file system used in Red Hat Enterprise Linux is ext4,the Fourth Extended File system.
In order to use the file system, we need to associate it with a mount point, and empty directory on a file system that is already available. Then the contents of that file system can be browsed as if they are the contents of the mount point directory. This is called as mounting the file system on the mount point. Read Full
So far we know that at local user accounts are managed through local files (/etc/passwd) on each machine. However, it is difficult to coordinate local user accounts on many systems.
In this blog, I will look at how to setup a machine as a client, to use a network user accounts that are provided by an existing LDAP (Lightweight Directory Access Protocol) directory service. This allows the LDAP directory to be our central authority for all network users and groups in your organization.Read Full
Linux software applications in the form of source code are available at different sites on the Internet. You can download any of this software and install it on your system. Recent releases are often available in the form of compressed archive files. Applications will always be downloadable as compressed archives if they don’t have an RPM version. This is particularly true for the recent versions of GNOME or KDE packages. RPM packages are only intermittently generated. Read Full
Hi Linux Users I will elaborate some basic tricks to know your CPU configuration on your Linux System.
