This is just a quick way to remember how to generate a user key for openvpn.

VPN - troubleshooting

Some tips to solve problems related to the Raspberry Pi VPN.

Artifactory - what is it ?

Today many projects are based on different libraries and code.
Usually the code on a project is stored in some repository, like github, but usually a lot of stuff is not stored in the github for a project.
For example, in order to create your project you need to have a compiler, libraries, modules, tools, etc.
Most of them are usually available on the net but ... but there are some limits.
What happens if you want to build your project in the future ?
How can you be sure to be able to find what "now" is easily available ?

Raspbian - prepare SD card

April 2019 - Update !
I already did in the past an article about a SD card preparation for Raspberry Pi.
The idea behind this article is to find a way to simplify and speeding up to prepare an image for a Raspberry Pi with Raspbian and beside, things change constantly.
Here what we need to do now to prepare a Raspbian image (no NOOBS !!!)

Squeezebox and VPN

With the VPN installed (My Little VPN) and few tweaks now I'm able to stream my music where ever I am from my Logitech Media server.

This article describes what I had to do on my Android phones to enable the remote streaming from my Logitech Squeezebox server.

On many Android phones I have, I used two apps to control the media server and stream music from it :

• SqueezePlayer (not free)
  This is the player for the phone, the app that receive the stream from the server
  
• Logitech Squeezebox Controller (free)
  This apps control the server, allow to choose the player and what to stream, radio, podcast or local music archive

These two apps works very well together and actually the SqueezePlayer links automatically with the controller.

However on newer versions of Android, the Logitech Squeezebox Controller is not working anymore.
That lead me to look for other applications to control the server, and I found two :

• Squeezer (free)
• Squeeze controller (not free)

Squeezer works fine in the network but for strange reasons is not capable to work via the VPN leaving the Squeeze controller as only choice.

So, to recap, on older versions of android (up to 4.4.4) I use the apps:

• SqueezePlayer (not free)
• Logitech Squeezebox Controller (free)

On newer Android versions (5.0), I ended up to use:

• SqueezePlayer (not free)
• Squeeze controller (not free)

Since my Logitech media player is totally behind firewall, i.e. there is not a public access (no open ports) it works only if the phone is connected to the local network.

With the VPN, without doing much effort, the applications recognize the server and allow the streaming without problems since the phone is actually IN the network.

On the VPN settings, I just enabled the Seamless tunnel and the ForcesAES-CBC option.

No specific settings for the Squeezebox apps.

Very nice to have everywhere your own music library.

My little VPN

Having around a Raspberry Pi I decided to set up a VPN to access to my network and from there, to internet.
There are a lot of tutorials, guides, suggestions, so in the end I opted for Open VPN since is well supported for Android, my main remote access to my network.
