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.

Link: Using a Raspberry Pi as an AirPlay Receiver

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.

by Admin

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: How to access ssh terminal in web browser on Linux

by Admin

Running “everything” in a web browser used to be a bold statement. However, due to the increasingly powerful HTML5/JavaScript stack, a web browser has now become a dominant application delivery platform. Even the Linux kernel sandboxed in a web browser no longer sounds so crazy these days.

In this tutorial, I describe how to access an SSH terminal in a web browser on Linux. Web-based SSH is useful when the firewall you are behind is so restrictive that only HTTP(s) traffic can get through.

Link: Raspberry Pi: the Perfect Home Server

by Admin

Ever since the announcement of the Raspberry Pi, sites all across the Internet have offered lots of interesting and challenging uses for this exciting device. Although all of those ideas are great, the most obvious and perhaps least glamorous use for the Raspberry Pi (RPi) is creating your perfect home server.

If you’ve got several different computers in need of a consistent and automated backup strategy, the RPi can do that. If you have music and video you’d like to be able to access from almost any screen in the house, the RPi can make that happen too. Maybe you have a printer or two you’d like to share with everyone easily? The Raspberry Pi can fill all those needs with a minimal investment in hardware and time.

Link: Solar Pi (powering a Raspberry Pi from the sun)

by Admin

About 10 years ago when Maplin opened a local store, I picked up some solar PV panels, a 40Ah sealed lead-acid (SLA) battery and a charge regulator on special. For the past 10 years these panels have been sitting in a window in my guest room doing nothing but keeping my battery nicely charged.

Finally, I’ve put this setup to some better use. I’m experimenting with the idea of keeping a Raspberry Pi powered 24/7 using nothing but PV panels and a battery. I’m based in Galway, Ireland (53N, 9W) and here we don’t get too much direct sun (clouds keep getting in the way :)… so this goal isn’t completely trivial.

by Admin

I am going to briefly describe how to connect to mythweb that is behind a firewall in a router. I will assume you have mythweb running. If you need help with that please see the mythweb documentation: http://www.mythtv.org/docs/ I will also assume that you know how to forward ports on your router. …..

Link: Check and Repair Your Filesystem With fsck [Linux/OS X]

by Admin

No matter how well you take care of your computer, sometimes, it will just crash and you often have to pull off the plug to restart the computer. When such crashes happen, there is a chance that your filesystem will get corrupted or damage. It is advisable to do a filesystem check regularly to make sure that it is running properly and free of error.

In Linux (and Mac), there is this powerful command “fsck” that you can use to check and repair your filesystem. “Fsck” stands for “File System Consistency checK”.

…..

An important thing to note is that fsck cannot be used on a mounted partition. If you do so, there is a high chance that it will damage the filesystem.

(emphasis added)

Check and Repair Your Filesystem With fsck [Linux] (Make Tech Easier)

One thing the article doesn’t mention is that you can avoid the problem of not being able to use fsck on a mounted partition by causing the system to reboot and then immediately run fsck. To do that, issue this command from the command prompt:

shutdown -rF now

The “-r” option means “Reboot after shutdown”, and the “-F” option means “Force fsck on reboot.” The two options can be combined into “-rF” as shown above. Unfortunately, that only works in Linux, not OS X, but if you’re already booted into OS X you can use Disk Utility to check your filesystem, and then you don’t even need to reboot.

Link: 11 Cron Scheduling Task Examples in Linux

by Admin

In this article we are going to review and see how we can schedule and run tasks in the background automatically at regular intervals using Crontab command. Dealing a frequent job manually is a daunting task for system administrator. Such process can be schedule and run automatically in the background without human intervene using cron daemon in Linux or Unix-like operating system.

For instance, you can automate process like backup, schedule updates and synchronization of files and many more. Cron is a daemon to run schedule tasks. Cron wakes up every minute and checks schedule tasks in crontable. Crontab (CRON TABle) is a table where we can schedule such kind of repeated tasks.

Link: How to identify video formats from command line on Linux

by Admin

If you want to know what video/audio codec are used for the video file you downloaded from somewhere, you can play the video itself. Most media player software such as VLC or MPlayer can display properties of a video file being played. However, there are command-line utilities that allow you to determine video properties quickly.

In this tutorial, I will describe how to check video formats from the command line on Linux.
