Hopefully you will also find it useful.

Installing Madsonic 5.1 the FREE Subsonic alternative on NAS4Free


Why Madsonic rather than Subsonic?

Madsonic is a fork of Subsonic the excellent cross platform web based media streamer which is free to use for media streaming but which has some ‘premium features’ only available by a low cost subscription.

Of particular interest to me was the ability to record, store, manager and stream my podcast subscriptions as there is nothing else similar which provides a web interface and cross platform APPs for mobile devices which works in NAS4Free. The Podcast capability comes under the Premium features of Subsonic. Madsonic being a fork of Subsonic works in a similar way to Subsonic, except it is truly free and Podcast management is included and runs exceptionally well in a BSD Jail in NAS4Free.

Install And Configure Nagios on Ubuntu 14.04 LTS


This is a great blog post on Unixmen about installing Nagios, an open source network and infrastructure software solution, on Ubuntu Server 14.04LTS. Not only does it cover the install but also a basic configuration for monitoring a networked computer.

http://www.unixmen.com/install-configure-nagios-ubuntu-14-04-lts/

If you do not know how to install Ubuntu Server 14.04.1LTS then read the following blog post on HowToForge

http://www.howtoforge.com/ubuntu-14.10-utopic-unicorn-server

If you have not got a spare computer lying around but have one with 4Gb of RAM, make it multi-purpose and install VirtualBox on it . Then install Nagios as virtual machine on Ubuntu Server under Virtualbox.

As with everything open source, the only cost is your time to install and your willingness to explore and learn.

Enjoy!

Installing Subsonic 5.0 on NAS4Free 9.2.x Embedded–PART 2


Installing Subsonic 5.0

Part 1 of this post can be found here

With the Subsonic Jail created, you now need to install Subsonic.

These instructions are based on https://lameguy.wordpress.com/2013/02/08/subsonic-install-in-freebsd-jail/

SSH into the Subsonic Jail by entering from Terminal

ssh root@xxx.xxx.xxx.xxx

e.g. ssh root@192.168.1.55

Enter the root password and you should be taken to a command prompt for NAS4Free!

enter

jls

this checks your new jail, you should see something like this

Installing Subsonic 5.0 on NAS4Free 9.2.x Embedded–PART 1


To be able to run Subsonic on a NAS4Free server you need to run it within its own separate environment which is called a Jail. There are different ways of creating a Jail within NAS4Free, this post is going to cover installing TheBrigg Jail manager. In part 2 we will look at how to install Subsonic within a Jail in NAS4Free.

PART 1 – Install TheBrig Jail manager

http://www.forums.nas4free.org/viewtopic.php?f=79&t=3894 and associated YouTube video

Note: All existing Jails must be removed from NAS4Free

Create a directory to contain your Jail, do this in the root of your data drive rather than anywhere else. in my case the directory was created on the first data drive called data1

From terminal SSH into your server and create a directory called Jail in the root of your share:

mkdir /mnt/data1/Jail

Change directory to the root of the share by entering

cd /mnt/data1

Now we are going to download the script from https://raw.githubusercontent.com/fsbruva/thebrig/working/thebrig_install.sh and save it to the current directory using the fetch command

fetch -o thebrig_install.sh https://github.com/fsbruva/thebrig/raw/working/thebrig_install.sh

If successful you should get something similar to the following

Installing MiniDLNA extension in NAS4Free


Before you start making any changes to your NAS4Free server, please remember to backup your config.xml file

Before you can install MINIDLNA on your NAS4Free server, you need to ensure you have SSH setup.

Configuring SSH Access

From the NAS4Free menu select Services > SSH

Check the Enable box on the right hand side to enable SSH.

In my screenshot below I have checked the Permit Root Login option, this is optional but useful.

Then click Save and Restart to start the service.

Mythbuntu 12.04LTS to 14.04.1LTS Upgrade


After holding off for five months, testing the point one release on a test MythTV server, I decided to bite the bullet and upgrade from Mythbuntu 12.04LTS to 14.04.1 LTS on the basis that this point release has addressed all the initial bugs identified in 14.01LTS.

The good news is that this is true, except if you are using the MythTV Web interface which breaks as a result of the upgrade Sad smile

The cause of the problem is that the Apache web server configuration file is broken because MythTV 12.04LTS had Apache 2 2.2. and Mythbuntu 14.04.1LTS has 2.4. The supported syntax changed between Apache releases and prevents the Apache server for starting.

Dual Booting the HP Pavilion Sleekbook 15 with Windows 8.1 and Ubuntu 13.10


The HP Sleekbook 15 was launched late in 2012 and if you get the Intel variant it comes with a 3rd generation Core ix processors (Ivy Bridge), offering good battery life for a 15.6″ laptop which is around five hours with average use or the AMD A series or processors. Graphics options are quite broad with either stock Intel HD Graphics 4000, AMD Radeon or nVidia GPUs. On some models there is even an option for a SSD drive although apparently you can’t install Ubuntu to thsi drive.

Much to my surprise you get s choice of pre-installed operating systems from HP:

  • Windows 8.x
  • Ubuntu 12.04LTS 64-bit – Certified by Cannonical, although this is only the Pentium Gen. 2 variant.

There are also touchscreen (Sleekbook Touchsmart) variants as well as 14″ screen versions making the model range quite extensive. Because all Sleekbooks are around 2cm thin, there is no room or a DVD drive and no external drive is supplied as standard. However, if you need one these are cheap to buy.

My own model is a Sleekbook 15-b052sa which was pre-installed with Windows 8 and uses a Intel Core i5 CPU (3rd gen) running at 1.7Ghz 8Gb RAM and now fitted with a 500Gb Seagate Momentus XT hybrid had disk drive replacing the stock 750Gb SATA drive.

As with all new computers they are supplied with the dreaded UEFI BIOS which adds aditional security to the computer whilst eliminating the traditional BIOS. For users of non-Microsoft operating systems and Microsoft ones before Windows 8 this has the potental of being an additional hurdle to jump. However, in reality this is not a deal breaker people make it out to be and is just different to the traditional way of installing an operating system with some additonal steps.

Encouraging Linux not to use the SWAP partition


I recently doubled the memory in my eee PC 1005HA netbook running Mint 16 from 1Gb to 2Gb and to try to maintain the 7 hours battery life I get out of it decided to reduce the possibility of it using the swap drive unless necessary. My initial thought was to delete the swap partition but after some research decided that this was not a good idea, it would be better to discourage Linux from using the SWAP partition!

I came across an excellent post written in 2012 by mikecrosoft in the Linux Mint Forums which clearly explains the steps. As I can’t improve it have reproduced it below. Of course this would apply to all modern day Linux systems, so I’ve since applied it to all of my desktop PCs and to my HP Sleekbook laptop.

Useful Utilities for Managing MythTV and Mythbuntu


MythTV is an excellent PVR, but on occasions thing can go wrong and it is useful to have a ready arsenal of utilities which you can run when things might go wrong!

Before your begin:

If you are not confident that a script won’t damage your database, it’s recommended you backup your database using the Backup and Restore feature in the Mythbuntu Control Centre
