RadioduinoWRT Today I want to present you one of my larger craft projects. This time it is not just about software, but also about the associated hardware. What is it? A web radio!
I like to listen to internet radio stations, but I didn’t want to run my pc only for listening to webradios. Connecting my phone to my stereo either wasn’t a solution, since I’d rather wear this with me, because I don’t want to run for each SMS / Whatsapp message to the music system. And because I always like to tinker, it was obvious to build a web radio as a standalone device myself.
As this article has become a bit longer, there is a brief overview of the following sections of the article, so that everyone can quickly find what he looks for.

raspberry pi logo Once we have clarified in this article how to set up a the DynDNS (Dynamic DNS) service for your domains rented at Namecheap.com, we will have to focus on how keep the IP/DNS records for each DynDNS domain up to date.
In another article I have explained how to do this using a Fritzbox. As for me, I have not only my Fritzbox 24/7 connected to the internet, but also my Raspberry Pi. So I will show you how to setup your Raspberry Pi to use it as a DynDNS client for use with Namecheap.
How to use Namecheap DynDNS service with ddclient on the Raspberry
Log into your Raspberry Pi (by ssh for example) or open a terminal window if you are working directly on Pi. In the first step we have to install ddclient, a […]

Mastering OpenSSH – Part 3: How to secure login by using a key file

Posted by Raffael on 05/01/2013 Posted in Linux, Tutorials Tagged how to generate openssh keys, how to login ssh with key file, open ssh for beginners, openssh, openssh private key, openssh public key, openssh tutorial, puttygen, ssh, ssh-keygen

After we set up an OpenSSH server in the first part and completed the basic configuration to secure the server in the second part of this article series, we now want to configure the server to make use of a key file (hereinafter also “key”) for the login process.
The SSH key authentication is based on the principle of asymmetric encryption. So we need a key pair consisting of a public key and private key. The public key is then stored on the OpenSSH server and the private key goes to the client.
The top priority here is to keep the private key secret forever and in any case. If someone else comes into the possession of the private key, he or she can log on to your server.
As a small obstacle you can provide the private key itself with a password. But nevertheless, if the private key gets public or falls […]

How to use Ubuntu software center on Linux Mint

Posted by Raffael on 04/21/201302/09/2017 Posted in Linux, Linux Mint, Tutorials Tagged alacarte, Linux Mint, linux mint ubuntu software center, ubuntu, ubuntu software center on linux mint

Linux Mint itself is well and good, but the included software management is admittedly not quite my thing. I personally think it’s quite sluggish (long loading times) and also eye candy looks different. Concerning the software center Ubuntu has done a far better job. And that’s why I want to show you today, how to get Ubuntu’s software center running up on Linux Mint.
In the first step the software center must be installed with the following shell command.

sudo apt-get install software-center

Then a python script must be created. Therefore you copy an existing script and edit it. See the following shell commands to get to know what exactly is going on.

sudo cp -r /usr/share/software-center/softwarecenter/distro/Ubuntu.py /usr/share/software-center/softwarecenter/distro/LinuxMint.py

In this script, you need to edit some lines. So replace

class Ubuntu(Debian)

with

class LinuxMint(Debian)

For this purpose, just open the file with the following command:

gksudo gedit /usr/share/software-center/softwarecenter/distro/LinuxMint.py

(Within […]

Bash script doesn’t work on Linux Mint

Posted by Raffael on 04/21/201302/09/2017 Posted in Linux, Linux Mint Tagged Dos2Unix, fromdos, Linux, Linux Mint, linux mint bash problem, linux mint bash script

Today I wanted to run (once again) a bash script on Linux Mint. (I had downloaded it from Pastebin.com). But unfortunately nothing happened. Not even an error message. Whereas solution was quite simple. The script was apparently stored with line breaks in Windows format (r), so the bash interpreter couldn’t parse it correctly.
Quick and easy solution was promised by fromdos. To repair the script, you just have to call the following command:

fromdos myScriptFile.sh

Should you have fromdos not yet installed, you can catch up by simply typing the following into a shell window.

sudo apt-get install tofrodos

And now, have fun fix you files! ;)
