Some handy tips: SSH Kunfu:

Or the putty tunnel way:
http://www.howtoforge.com/ssh_key_based_logins_putty_p3

Putty .PPK key to SSH key

ubuntu sudo apt-get install putty putty-tools

1	ubuntu sudo apt-get install putty putty-tools

command line:

puttygen key.ppk -O private-openssh -o key.ssh

1	puttygen key.ppk -O private-openssh -o key.ssh

log onto your system:

ssh user@server.com -i key.ssh

1	ssh user@server.com -i key.ssh

Add your key to your linux shell:

ssh-add /path/key.ssh

1	ssh-add /path/key.ssh

More to come I think 🙂

Add a line to the file in /etc/rc.local just before “exit 0” to execute the script at boot and before the login screen.

Connect to Google cloud print with linux

01/06/2014

So you got a linux machine and you want it to print to your google cloud printer.

Just follow this page to set it up with cups: http://www.niftiestsoftware.com/cups-cloud-print/

I used the .deb for my backboxlinux distro.

wget http://niftyrepo.niftiestsoftware.com/cups-cloud-print/packages/cupscloudprint_20140308-1_all.deb 
sudo dpkg -i cupscloudprint_20140308-1_all.deb  
sudo /usr/share/cloudprint-cups/setupcloudprint.py

wget http://niftyrepo.niftiestsoftware.com/cups-cloud-print/packages/cupscloudprint_20140308-1_all.deb

sudo dpkg -i cupscloudprint_20140308-1_all.deb

sudo /usr/share/cloudprint-cups/setupcloudprint.py

Then just follow the questions. It will ask you to open google to give the app some permissions. Google will create a code that you will have to enter.

It really is that simple

Book review: Linux Mint Essentials

28/05/2014

a few day’s ago I seen a post on facebook about reviewing a book called “Penetration Testing with BackBox”. Such a pity that I was to late for it but Priyanka from Packt Publishing gave me the opportunity to review Linux Mint Essentials.

Now I am not a novice with the enormous amounts of different Linux distributions. I am chrunchbang and BackBox minded. I tried Linux mint once. Thought it was a nice distro but it just wasn’t my thing. Might be the fact that Linux Mint is finished.

Anyway back to the book.

The eBook (PDF) is a 12 MB download, Has a good chapter index and is clearly written. The title says its for Linux Mint but because its based on Ubuntu other novice users might be interested in the book to.

Its starts with the many way’s to create a boot disk and what I realy liked what kinda desktop and menu’s you want to use. For Mint you have the option to look at and work with four different desktop environments KDE, Xfce, MATE and Cinnamon. They writer explains the difference between the four choices.

After we have installed Linux Mint the book goes more into getting to know the Cinnamon environment because its most popular Mint flavour. At the end of the book the author takes the time to take a dive with you into MATE and the KDE version of Linux Mint.

My conclusion:

If you are a novice user or curious about the standard software, this book is for you. From chapter 11 on this gets interesting for the more experienced user. Its about securing, tweaking, updating and upgrading your Linux Mint version. Again, if you use an Ubuntu based Linux distro, this might also be learn full. Its well written and it will take you from a novice to a Linux Mint User who knows how the system will work.

EZ430-CHRONOS a watch that comes with a screwdriver

06/01/2014

Texas Instrument was so kind to send the eZ430-Chronos Development Tool.

Its a watch that comes with an USB programmer and an USB access point and a screwdriver! YES no kidding! Although you can connect with it wireless you are actually encouraged to open the watch and use the usb programmer! Its on the market sinds 2010 and evolved a bit in time. I was lucky to get the latest version.

The Specs: Its has these sensors in it:

temperature sensor
battery voltage measurement
integrated pressure sensor
3-axis accelerometer for motion sensitive control

To make it more fun it can also act as a hub for a speedometer (pedometer) and heart rate sensor.

There are loads of options you can do with it. Just see for yourself if you’re interested.

It comes with its own “Control Center” software and you can build your own software/firmware with Code Composer.

What I really like is that you can control you pc with this watch very easy. And amazing.. its can show you the time too! YES! Its like you can use your mobile to make phone calls!
