This post is a follow up of my previous post about using Raspberry pi as a media server and a torrent box. Since last time, I’ve managed to fix up most of the problems that came up and now my Raspberry Pi setup is working well as a media server and torrent box. The major update is that the whole rig sits inside an old metal ammunition box. I went out of city for 4-5 days twice in last 6 weeks after turning it on and the whole thing worked extremely well.  It boots up and starts all required processes in case of a power failure without any intervention. As of now it’s not accessible from internet, but I’d rather keep it this way . May be if something comes up in near future then I might think about enabling connections from other networks, but it’s pretty much adequate for now. I had taken some pictures while doing all this, but can’t  find them.
Since last time, I’ve moved the whole set up in to an old metal ammunitions box salvaged from a junkyard. The boxes were not exactly in good shape.  Dust and random debris was everywhere and there were big patches of rust where paint had been chipped off. So my first job was to clean the boxes by a blower, then washing them with water. Later on, I applied some rust remover on rust patches to clean away as much rust as possible. After this point, I applied a coat of clear spray paint on whole box.  It prevents further rusting and creates a nice shiny coat.
Next I bought an extension cord and took out the cord. After fixing the board inside ammunition box, I drilled a hole in the box using my drill, hammer and a file. It wasn’t an easy job with the tools I had. Proper tools for this kind of work in such a metal box are way too expensive. It isn’t exactly clean, but does the job. Now as I’m writing this, I now realise that the hole should’ve been bigger but too lazy to change it now. Next step was to solder the wire of extension cord back which was unexpectedly more difficult than I anticipated. Rest was pretty easy. Hard disk is placed on a aluminum heat sink salvaged from an old graphics card. Rest of the stuff like Raspberry Pi, USB hub and extension board are stuck using double sided tape to interior of box. This whole setup by  itself is pretty rugged and can take some rough handling apart from the power adapter which is a bit loose in extension board.
I was also thinking about installing a cooling fan to dissipate some heat, The fan from that old graphics card is just right for the job. It can be powered by attaching it to a USB cable powered by the USB hub. It’s voltage rating is higher but it ran perfectly fine on 5 V when tested. But the temperature of Raspberry Pi never exceeded 51 degrees even in  40 degrees weather, so dropped the idea.
I’ve also installed Kodi on it and now it can be connected to the TV via HDMI and media played live. Streaming as described above works too, but finding a particular file to play can be difficult when you have a large number of files with no proper naming convention. Kodi can also be accessed over HTTP but haven’t had the time to check the functions yet.  Attached to TV via HDMI, it works pretty well. All of this can be controlled via TV remote or any of dozens of Android apps. The whole setup remains mostly powered on unless I am not streaming, downloading or seeding something. Pi can be shutdown remotely but haven’t tried to enable remote power on option yet.
After purchasing a Netflix subscription, it seems that this box will not be as heavily used, but is still pretty vital considering the limited library available in India.
Following configuration changes were made since last post:
1) Transmission as a torrent client and it’s web interface start automatically at each boot up.
2) File sharing service Samba for accessing files on attached hard disk from other computers on network.
3) miniDLNA for streaming media to other devices.
4) Health and running status of setup can be checked via NoMachine and Android applications based on ssh.
Following are configuration files, mostly for my record:
# Sample configuration file for the Samba suite for Debian GNU/Linux.
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which
# are not shown in this example
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
#  – When such options are commented with “;”, the proposed setting
#    differs from the default Samba behaviour
#  – When commented with “#”, the proposed setting is the default
#    behaviour of Samba but the option is considered important
#    enough to be mentioned here
# NOTE: Whenever you modify this file you should run the command
# “testparm” to check that you have not made any basic syntactic
# errors.

A few weeks back I bought a Raspberry Pi 2 with a vague idea of using it as a device for downloading torrents and streaming videos. Using a PC for this work seems like an overkill. But work, travel and other stuff didn’t leave enough time and I could work on this project only for a few minutes every week. There were  a few problems and it delayed the whole project further. But after some effort, almost everything is ready and working fairly well. There are still some things which need to be sorted out, but it meets my needs for now. I will keep on tinkering to improve and sort out the kinks. This post is about the equipment, it’s configuration and use. I am not writing down all the details as most of procedures I used are easily found on internet. To begin with, I bought the following stuff:

Raspberry Pi 2 Board.
A plastic case.
Power adapter and USB cable.
A USB WiFi adapter.
HDMI cable.
HDMI to VGA adapter.
Cat5 Ethernet cable.
A memory card with OS pre-installed.
A pen drive I already had. Will replace it later with a hard disk.
Used keyboard, mouse and monitor of my existing PC.

1st Phase, WiFi:

First step of the project was to assemble everything and connecting it up to a monitor which was trivial. essentially it becomes a matchbox sized personal computer. As the seller had already installed an OS on it, I just booted and started working. But the WiFi adapter included just refused to work. I must have spent more time on this adapter troubleshooting than rest of the steps combined. Then I gave up on it, reset the system and downloaded a new version of OS. Surprisingly my older and new USB Wifi adapters both worked fine without any need of installing any drivers.
2nd Phase, Command Line and GUI access:

Once connectivity issue was solved, I configured SSH server and installed NoMachine for remote GUI login as unplugging and plugging in monitor and keyboard wires was becoming annoying. SSH had some problem in beginning, but was fixed easily. After this, I could access the Raspberry from my phone and PC. NoMachine can also be used from android.
3rd Phase, External Storage :

Adding this was pretty straight forward. Make a folder, mount it, apply necessary permissions and make it mount on every boot.
4th Phase, Torrent client :

Installed a torrent client, Transmission. I needed a torrent client which can be accessed via a web GUI. There are 3-4 options available and I tried them all before settling on Transmission. I still can’t get the web interface to run on every boot, but I am working on it and hopefully will be able to sort it out soon. I also tried Deluge and rTorrent, but wasn’t really satisfied with them. In the meanwhile, Transmission works fairly well.
5th Phase, External IP access:

Another step which I still haven’t figured out is how to allow access to Raspberry from an external network. I have downloaded and installed NoIp client which works well. But for some reason, port forwarding is not working as it should. So I can control the setup only when I’m connected to home network. It’s not really a big issue right now and I expect it to be solved soon.

6th Phase, Media Server:

Next step is to stream the videos to my TV and android tablet. Thankfully, it’s a smart TV so there is no need to buy another gadget like Chromecast to enable networking. Enabling this feature on Raspberry pi was achieved by installing MiniDLNA. Takes 2-3 minutes to install and configure. My android tablet can stream movies to TV but can’t play streaming videos by default. I tried ES File Explorer first which worked, but didn’t really liked it that much as it seemed too bloated. Installed iMediaShare which works pretty well.

So this is the basic overview of my new setup of downloading movies and watching them on TV and android tablet. I can access media on my Raspberry Pi, Tablet and  Still needs some fine tuning but does the job for now.

Since last 3 months, I am on an shitty internet connection which as a download limit of just 15 GB and costs an arm and leg. But stuck with it because the only other option in my area is just as bad. So now it happened that this 15 GB download limit was getting over within 4-5 days and rest of the duration the bandwidth gets throttled to snail like 512 Kbps for rest of the month.  All of this data was gone while I was not using any bandwidth intensive application. No torrents, videos, music streaming. Just the usual work on Opera and Chrome browsers and email.

This was bugging me too much because my current ISP (Failtel Fraudband) is notorious for shady business practices and ripping off customers. So to be doubly sure, I downloaded and installed Glasswire application to monitor my bandwidth usage.

Bandwidth usage report

Bandwidth usage report

As clear from the report above, Google Chrome is the largest bandwidth hog even though it’s my secondary browser and it mostly runs in background while I do my work on Opera. All of this bandwidth was consumed in just about 2 hours that I had it on.  While looking for a solution, I  found many people complaining of the same thing and found out that Google Chrome pre-fetches data from some most frequented websites and also automatically downloads some data from other links on the websites you are on.

Make webpages load faster

You can make webpages load faster by telling Google Chrome to prerender (preload) links. Google Chrome does this by predicting what links you might click, preparing them to load instantly for you.

For example:

  • When you’re browsing a blog, you might click “next post” when you’re done reading. The blog can tell Google Chrome to pre-load the “next post,” so the page shows instantly when you click it.
  • When you’re typing a web address in the address bar, Chrome will begin to prerender that page if it’s confident about which site you’re likely to visit (based on your local history). This will make the page show up faster when you hit enter.
    Google’s Instant Pages search feature in Chrome is powered by Chrome’s prerendering technology.



While this is a good option for connections with unlimited bandwidth, it is just a nuisance for others.  This means that the Chrome is pre-fetching data from websites which in a number of instances is just a waste of bandwidth. This option can be found by following steps as explained in above mentioned link:

  1. In the top-right corner of the browser window, click the Chrome menu icon .

  2. Select Settings.

  3. At the bottom of the page, click Show advanced settings.

  4. In the “Privacy” section, check “Prefetch resources to load pages more quickly.” If you want to undo this permission, simply uncheck the box.

As I wanted to save bandwidth, I unchecked the box.  After disabling this option, I kept Chrome running for half an hour and the bandwidth usage was minimal.

While looking for detailed logs, I also found out that Mozilla Thunderbird, which I use as my primary email client was also a big bandwidth hog, downloading 176 MB bandwidth in a single day. While I use it almost all day long, usage of this much data for text emails is way too much. By default, Thunderbird checks for messages every 10 minutes. I increased that interval to 30 minutes in Account Settings as visible in screenshot below.

Increase duration of checking messages in Thunderbird

Apart from that, a major bandwidth hog is the countless number of people sending messages with huge attachment, useless images and too many scammers and spammers with their malicious attachments. In the same menu, you can find option Synchronization & Storage.

Size limit for downloads in Thunderbird

In this, you can tell Thunderbird to not download any message bigger than your specified limit. I put in 1000 KB, but you can use any value you want. Additionally, the option just above “Synchronize the most recent” can also be given a lower value to decrease the amount of data spent on mostly un-needed traffic.

This work was done on Windows 7. I don’t know if the settings are same on Linux, but there is no reason that anything will be different.


This tutorial is meant for people who are want PHP5 on their Ubuntu computer along with Apache2, but can’t seem to make it happen. I’ll just explain it all as it happened to me.

I have an old pc running BackTrack 4 R2 which is used as a MySQL server. It’s Ubuntu version is Intrepid, which isn’t officially supported anymore. As it happened, we needed to run a small webserver on it with PHP support. Although Apache2 is installed and running fine, server wouldn’t handle PHP files and will just offer them as download instead of processing them.
Now the first step is to install PHP.

Now, as I said before, my Ubuntu version is old and not supported, I had to manually change my repository list at /etc/apt/sources.list and add the following lines:Continue reading
