To generate a SSH key pair use the command 'ssh-keygen'. $ ssh-keygen -t dsa This will ask you to enter a file to save the key. The default is '.ssh/id_dsa' in your home directory. Generating public/private dsa key pair. Enter file in which to save the key (/home/dipin/.ssh/id_dsa):  Press 'Enter' to accept the default. Now it will ask for a passphrase and will ask you to re-enter to confirm. Generating public/private dsa key pair. Enter file in which to save the key (/home/dipin/.ssh/id_dsa): /tmp/key Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /tmp/key. Your public key has been saved in /tmp/key.pub. The key fingerprint is: 8d:f7:d8:d1:b6:ea:c2:a7:a4:fd:ff:6f:95:06:bb:0a dipin@dipinkrishna.info You will get a private key file and a public key file with '.pub' extension.

How to convert our computer screen on to a digital electronic whiteboard, under Linux, could not be simpler.

Most of us run multiple Operating Systems on our PC's and are connected to LAN with machines running different Operating Systems. Now, Linux even though is sort of immune to viruses (there are few viruses, and Linux can get infected ) most of Desktop Linux users don't need Anti virus tool, but there are people who run Windows and there are umpteen number of Viruses, Worms and Trojans for Windows and removing them can be difficult. Running Antivirus tool on Linux can be especially helpful in such cases , searching and removing viruses from a different Operating System would definitely help speed up the process and prevent Viruses from interfering with AntiVirus's scan process, also for PC's connected to LAN, Anti virus for Linux could detect any virus laden file transfer prompting one to take appropriate action and prevent virus from spreading to other PC's on the LAN. There are couple of AntiVirus tool available on Linux, and in this article I would look into AVG Fr...

I found this post by carla interesting. This is what is says: Virtualization, especially with nice virtualizers like VirtualBox and KVM, makes it easy to run multiple guest operating systems and not have to hassle with rebooting, like you do with a multi-boot setup. But I still favor multi-booting for testing new Linux distributions. There are fewer hassles with networking and file-sharing, and when there are problems I don't have to figure out if it's something weird with the VM. The common wisdom is to have a shared home directory in a multiboot setup, but this has its own set of potential problems because it mixes data files and configuration files. So when you're trying out different distributions, your desktop settings may not translate gracefully across all of them. So what's the answer? The answer is simple: create a separate data partition, and let every distro that you install have its own unique ~/home for your dotfiles. You'll jump through a couple of ex...

Looking for an application that would allow you to take notes, draw sketches and insert images , it's like i have found for you - Jarnal . Jarnal is an Open Source platform and written in Java, similar to Windows Journal . Supports collaborative writing, a feature that allows multiple authors to edit a single file in real time over a network. Another important feature is that it allows you to create and export presentations created with formats pdf, html, and text (only text, the figures are not exported) . Being written in Java, only requires at least Java 2 1.4.2. This application can be found in the openSUSE Build Service under the repository Open Source Software by the method or one-click install . The official website of the project can be found here . For demos: There is a simple on-line demo and and a more advanced (and fun) demo demonstrating networked usage . See what the developers says... Why is this program better than Microsoft Windows Journal or One-Note? Because...

In Linux there is a variety of audio players and some really very good, not for the fact that play music correctly, but they do all the comforts and accessories that we offer. I made a small collection that I think are the best and most well known, it is clear that this is based on my tastes so I strongly recommend to comment on this post which is more suited to your tastes: Amarok: which i like use every day to listen to the music, a lightweight player that has everything you need, multiple playlists, integration with other KDE applications, it downloads lyrics from the Internet, socialized through Last.FM, information of the artists on wikipedia, apparently set by CSS ... as you can see an endless list that makes it my favorite player without doubt. Exaile: uses GTK + and the features I'm very similar to those found in Amarok. Banshee: I have to stress this for its ease of operation. And the library is great for people who have a large collection of songs on your hard disk. Y...

Wine one of the best known Windows emulation systems under Linux platform now has an excellent graphical environment called WineXS.

Arista is a wonderful video format converter that anyone can use without any knowledge, its performance is really very simple, but its main purpose is to streamline the full process of converting a video giving a few options that are easily understood for us users: Convert to Apple iPod, Cowon D2, Computer, DVD Player, Sony PSP or Sony Playstation 3. One of the features I liked most of Arista is the ability to preview video looks like without having to wait until it finishes its conversion, in this way can we know if we feel we must correct or select another. Arista also allow us to extract and convert video or DVD directly from any camera connected to your PC without the need for additional software. Download Arista

Monitor the CPU usage of applications that we use, it is recommended if you need to maintain a good performance on your system, sometimes in our system we have applications that should not stop working and we need some free resources on your computer for them. Linux can prevent other applications to consume these resources and the applications work properly within a cpu limit. To install in ubuntu: $ sudo apt-get install cpulimit It is in the universe repositories. To install it on any other Linux distribution follow this: $ wget http://downloads.sourceforge.net/cpulimit/cpulimit-1.1.tar.gz $ tar-zxf cpulimit * xxx.tar.gz $ cd cpulimit-xxx $ make Use it To use it, you will need to know the name of the application or PID, once you know it: Examples of use If we want to avoid that Firefox does not exceed 30% of CPU usage type cpulimit -e firefox -l 30 In the case of wanting to limit the process with PID 3675 to use only 40% CPU at maximum, for that type on your console as f...

Internet Relay Chat (IRC) is a form of real-time Internet text messaging (chat) or synchronous conferencing. It is mainly designed for group communication in discussion forums, called channels, but also allows one-to-one communication via private message as well as chat and data transfers via Direct Client-to-Client. IRC client software is available for virtually every computer operating system that supports TCP/IP networking. IRC is based on a line-based structure with the client sending single-line messages to the server, receiving replies to those messages and receiving copies of some messages sent by other clients. The basic means of communication in an established IRC session is a channel. Channels in a server can be displayed using the IRC command LIST that lists all currently available channels. Channels that are available across an entire IRC network are prepended with a '#', while those local to a server use '&'. Other non-standard and less common channel ...
