Link: 10 Things And More That ‘apt’ Can Help You With!

by Admin

One of the most used tool in Linux is ‘apt’. So, if you are a Linux user or if you are planning to give it a try, there is a 100 per cent chance that you will stumble upon apt. The fact is that ‘apt-get’ is one of the biggest contributer in making the Linux life so much easier. With this, you do not have to worry about how to install and remove software on the Debian GNU/Linux distributions.

…..

In simple words, if you need to install, remove and update packages apt is the tool for you. Here are 10 utilities that ‘apt’ can bring to your Linux machine:

Link: How to synchronize files between two servers

by Admin

Suppose you have a collection of files which are replicated on two different servers. The two replicas are then modified independently, and you want whatever changes made in one replica to be propagated to the other, so that both replicas remain in sync.

There are several file mirroring tools on Linux, such as rsync or duplicati. However, these tools are meant for “uni-directional” file sync (i.e., pushing or pulling incremental updates in one direction), and so two-way sync would require running such tools twice, one for each direction.

Unison is an open-source file synchronization tool that natively supports bi-directional file synchronization. Unison is available on multiple platforms including Linux, FreeBSD, Windows and MacOS X. In Linux, Unison is available as a command-line tool as well as a GUI program with GTK+ interface.

In this tutorial, I will describe how to synchronize files between two servers with Unison command-line utility.

by Admin

Shell In A Box (pronounced as shellinabox) is a web based terminal emulator created by Markus Gutschke. It has built-in web server that runs as a web-based SSH client on a specified port and prompt you a web terminal emulator to access and control your Linux Server SSH Shell remotely using any AJAX/JavaScript and CSS enabled browsers without the need of any additional browser plugins such as FireSSH.

In this tutorial, I describe how to install Shellinabox and access remote SSH terminal using a modern web browser on any machine. Web-based SSH is very useful when you are protected with firewall and only HTTP(s) traffic can get through.

by Admin

Linux is built with certain powerful tools, which are unavailable in Windows. One of such important tool is Shell Scripting. Windows however comes with such a tool but as usual it is much weak as compared to it’s Linux Counterpart. Shell scripting/programming makes it possible to execute command(s), piped to get desired output in order to automate day-to-day usages. In-fact automating these day-to-day task on server is an important task, system administrator has to perform and most of the admins achieve this by writing scripts to be executed as and when required.

We have tried to cover a large variety of shell programming on a number of aspect in 5 different posts.

Link: Setting Up A Linux File Server Using Samba

by Admin

A quick Google will show many ways to to setup a Linux file server running Samba, most of them however don’t work! Some leave out important bits leaving you stuck and some will only work with one version of a specific Distro (but of course don’t mention this). I struggled for ages getting Samba to work reliably and made quite a few wrong turns on the way. I was just trying to set up a simple Linux file server to store music, photos etc. but eventually found a foolproof (probably) way to do it. The following works and has been tested several times on fresh installations. This is not meant to be a high security setup, all folders are accessible to everybody for read, write and delete. If you have stroppy teenagers who want exclusive access to their own area on the server, then you can use this as a starting point. A few simple changes would achieve that level of security but it is beyond the scope of this tutorial.

by Admin

The Raspberry Pi is a versatile little computer that provides the perfect sandbox to start creating some fun and interesting projects. One popular project is as an AirPlay receiver, allowing us to stream audio from an iOS device or computer using iTunes to our Raspberry Pi that’s connected to a set of speakers.

In this tutorial, I’ll show you how to set up a Raspberry Pi to be used as an AirPlay receiver so you can stream audio from any iOS device, iTunes or compatible AirPlay software such as AirFoil.

arkOS is an open source project designed to let its users take control of their personal data and make running a home server as easy as using a PC

…..

arkOS is not a solution to the surveillance state, but it does offer an alternative to those who would rather exercise some measure of control over their data and, at the very least, not lock away their information in online services where its retrieval and use is at the whim of a corporation, not the user.

Link: Basic Linux Shell Scripting Language : A Simple BASH Script to Test Your Internet Connectivity

by Admin
Most of the users all over the world make use of Google’s Index Page to check whether their Internet connection is working or not.  Many times it is required to check periodically whether the server you are running is connected to internet or not. It is very cumbersome to open the web page every time you wish to check the connection. As an alternative, it definitely makes sense to run some scripts in the background periodically scheduling them using cron.

The bash script that can be used for this purpose is given below:

Link: VNC and SSH on Raspberry Pi Without Display

by Admin

Here is a small walk through of how to install SSH and VNC on Raspberry Pi…

What is SSH? I really did not know the abbreviation until I googled it. It stands for “Secure Shell”. To be brief, with SSH connection between RPI and another computer, you can access the terminal prompt of RPI from the other computer (say your PC). Thus you will be able to execute commands remotely for the RPi from your PC without the need for a keyboard and mouse.

What is VNC? Virtual Network Computer. It is just like team viewer or any other remote desktop stuff, with which you can see your RPi’s desktop on your PCs screen, enabling GUI based access of RPI.

Assuming that you have an SSH enabled RPI, the tutorial follows.
