Ultimate Seedbox Tutorial (Step-By-Step)

14:05 Posted by Jurgens Krause , , , , , , 1 comment

Setting up your own seedbox from scratch, step by step tutorial.

While Ubuntu may not be the most lightweight Linux distro available, ti does make things very easy. I will be using Ubuntu 14.04 Server. I developed this tutorial using VirtualBox, but if you have a spare laptop or old pc, that will work just as well.

I will show you how to install Ubuntu 14.04 server, install the latest version of Deluge, including the daemon and web interface, as well as set up a basic FTP server and Samba share to access your downloads.

Asterisk Out of Office Recording Extension

12:34 Posted by Jurgens Krause No comments
My clients sometimes need to put temporary messages on their phone lines. For example during the Christmas holidays or if everyone is away for a company retreat.

This is a simple edit to your dialplan, so it should not be too difficult.

Static Netflix Routes

12:18 Posted by Jurgens Krause , , , 5 comments

A lot of people have multiple internet connections and use static routing to determine which connection a certain application uses. This is also true if you use a VPN connection to get access to services like Netflix/Hulu or other geo-locked services.

I have created this route list which works well with UnoTelly, but should work equally well for any other provider.

Ubiquiti Airos 5.6 CPE on Cacti

20:31 Posted by Jurgens Krause , , , , 26 comments

Ubiquiti has created a new MIB definition to go with the new version of AirOS.  I made myself some new templates to monitor 5.6 version AirOS devices, I will try to update the templates when the 5.6 goes final.

I am working with Cacti version 0.8.7i since that is the current version available to apt-get install on Ubuntu 12.04.

802.11 Networks on Radio Mobile (Part 2) - Coverage Maps

15:53 Posted by Jurgens Krause , , 1 comment
Now that we have mastered point to point links using RM, the next major feature is generating coverage maps.

For this tutorial we will be continuing with our Fictional WISP, SaharaWisp. We already have our two highsites configured, and we have a link running between the two. We are now going to be adding two 5.8ghz sectorized antennas to each tower, and plotting the resulting coverage.

Start by opening your existing network file in Radio Mobile.

802.11 Networks on Radio Mobile (Part 1) (Step-By-Step)

14:03 Posted by Jurgens Krause , , , , , 3 comments
Before reading this tutorial, you might want to take a look at Introduction to Radio Mobile

This tutorial will cover the creation of your first 5.8 ghz network with a single point to point link. You will learn how to create units, set network parameters, and create a point to point link profile.

Introduction to Radio Mobile

11:23 Posted by Jurgens Krause , , No comments
Radio Mobile is a free (not open source) RF Propagation simulator. Originally intended for amateur radio operators, the software is also perfect for plotting long distance wireless links on the 2.4ghz and 5.8ghz bands (and any other for that matter).

You can find thorough documentation for the software on but I would like to make a few tutorials specifically geared towards 802.11 networks.

Raspbian on Windows with Installer (VirtualBerry)

08:13 Posted by Jurgens Krause , , 2 comments

Getting Raspbian running on a virtual machine can be very useful if you do development, or just want to play around. Easy to use solutions like VirtualBox unfortunately cannot emulate anything other than x64 or i386 CPUs, while the Raspberry runs on an ARM chip.

Enter Qemu, an open source virtualization host that can run on Windows, Mac or Linux and emulate a wide variety of CPUs, inlcuding the ARM chip that the Raspberry Pi is based on.

I have created an installer for Qemu that is preconfigured with the latest Raspbian image (Jan 2014) at the time of writing this, but still there are a couple of steps required to get it working 100%

Radio Mobile Installer

08:41 Posted by Jurgens Krause , 8 comments
Radiomobile is one of the best RF propagation modelling programs, and certainly the best free one available. One of the drawbacks has always been that it does not come with an installer, so, with the permission of the developer I have created a simple installer for it. It includes all the Radiomobile languages. Although it is not officially sanctioned, it was created with the input of the developer of Radiomobile.

Please note that this installer is still in development, but every effort has been made to ensure that it is without errors. If you find an error, please report it in the comments section.

You can download the installer here:

Mikrotik Hotspot Data Limit Trial

16:26 Posted by Jurgens Krause 34 comments
Mikrotik's hotspot service is quite amazing considering what it costs. It does have some limitations though. One of these is the fact that you cannot set a data limit to the trial account, only a time limit.

Luckily there are a few workarounds for this, the original concept for this comes from but I have corrected a couple of bugs and added some functionality.

Mikrotik The Dude on Ubuntu 12.04 LTS Server (Step-By-Step)

11:12 Posted by Jurgens Krause , , , , 11 comments

On my network I have a single, low power server, running on my single highsite. This server runs Ubuntu 12.04.2 LTS, and it does not have the oomph to virtualize windows for the sake of dude. To this end I have deployed The Dude running under Wine.

Dude is a network monitoring application by Mikrotik that is excellent for monitoring Mikrotik and other SNMP enabled devices.

We will not be compiling anything, opting rather for the easier apt-get installs where possible.

This tutorial is based off the instructions from the Mikrotik Wiki, but adapted for Ubuntu 12.04 and The Dude Version 4.0 Beta 3

Asterisk PIN based dialing

10:31 Posted by Jurgens Krause , No comments

As an Asterisk administrator, I often have clients requesting the ability to have users enter a PIN before dialing. This is useful on factory floors where users roam between different phones, but still need to be held accountable for their calls. Apart from just authenticating the user, the dialplan also has to ensure that the account code is correctly assigned in the CDR.
To this end Asterisk provides the AUTHENTICATE dialplan application.

Mikrotik Hotspot - How to install Login Page Templates (Step-By-Step)

15:34 Posted by Jurgens Krause , 20 comments
I hope to post new templates as 'n adapt them for my own use, so keep an eye on the templates page.
Please note that some of these I did not create myself, I found them online for free, and adapted them to work with Mikrotik.

To install the template on your hotspot:

1. Connect to your Mikrotik router using winbox
2. Open the "files" window
3. Drag the "hotspot" folder from the zip file onto the root of your router's file system

Remember to check out my login templates here.

Supercharge your mRemoteNG

09:19 Posted by Jurgens Krause , , , , , 2 comments

If you are anything like me you have at least 50 different computers that you need to manage remotely. If you use Putty for ssh, WinSCP for file copies, VNC for desktop access and Microsoft RDP for managing Windows machines, you will know how hard it can be to keep all your logins organized.

mRemoteNG is a fully featured, tabbed, remote access manager. It seamlessly integrates with RDP, Putty, VNC and even has an integrated web browser built in.

What makes mRemoteNG even more useful is it's ability to integrate external tools. Now, for you these may be differ from the ones I find useful, but I will list my favourites as examples.

Asterisk - Outbound Whitelisting

16:07 Posted by Jurgens Krause , 4 comments
There are numerous ways to handle outbound whitelisting on asterisk, but I needed a solution where the end user could simply ftp a text file to the server to update the whitelist.

Setting up a Mikrotik Hotspot with UserManager (Step-By-Step)

15:14 Posted by Jurgens Krause , , , 133 comments
Mikrotik RouterOS provides a very powerful Hotspot Feature. This can be used with the Mikrotik built in Radius server (Userman) or with a remote Radius/Freeradius Server.

You will need:

Mikrotik RouterBOARD:

  • Level 4 or better licence (Lower licences will allow only a single Hotspot client)
  • RouterOS 6.x (5.x will also work, but this tutorial is based on v6.7)
The network will be configured as below. You may need to adjust the IP Addresses to suit your needs

Mikrotik Hotspot Network

The RouterBOARD CPU and RAM will directly affect the performance of your Hotspot, so consider beforehand how many clients you wish to connect.
A RouterBOARD 750 can comfortably run about 25-50 users.
In my example I will use a RouterBOARD 532 with one 2.4ghz WLAN card
