Linux 4.7 will have security features of Chrome OS

linux and chrome

Very recently we have available the latest Linux kernel. But Linus Torvalds and his team are already working on Linux 4.7, the next kernel team. At the moment we know little about Linux 4.7 but how little we know is already interesting.

 

Apparently this new version will have a new security feature that has been ported of Chrome OS, a security feature called LoadPin. This new version will be interesting for the field of security, since LoadPin avoid loading modules and that affects the integrity of the kernel.

LoadPin is an interesting feature that will Linux 4.7 and that will not only full confidence modules  in the kernel to load, but once loaded not be loaded more modules or simply restrict loading modules so that no “sneaking “new modules in the system.

LoadPin comes from Chrome OS but is an interesting feature for many, but especially for the business environment that will allow the kernel safer with this new feature, because it will not allow dubious code modules that add meaningless.

The current intention of the team is to improve the kernel Linus and therefore LoadPin is a great security tool. But not the only innovation in Linux 4.7, but unfortunately I do not know the new tools to be integrated into Linux 4.7.

Personally I find interesting LoadPin and wonder because the team did not include this function in the Kernel 4.6 or earlier versions. In any case it is clear that the more free software projects exist, more profit is the end user

SSH login without password

ssh

You want to use Linux and OpenSSH to automate your tasks. Therefore you need an automatic login from host A / user a to Host B / user b. You don’t want to enter any passwords, because you want to call ssh from a within a shell script.

 

First log in on A as user a and generate a pair of authentication keys. Do not enter a passphrase:

a@A:~> ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/a/.ssh/id_rsa): 
Created directory '/home/a/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/a/.ssh/id_rsa.
Your public key has been saved in /home/a/.ssh/id_rsa.pub.
The key fingerprint is:
ae:ff:03:74:ba:7f:66:73:3x:35:45:f5:c7:ac:57:a6 a@A

Now use ssh to create a directory ~/.ssh as user b on B. (The directory may already exist, which is fine):

a@A:~> ssh b@B mkdir -p .ssh
b@B's password: 

Finally append a’s new public key to b@B:.ssh/authorized_keys and enter b’s password one last time:

a@A:~> cat .ssh/id_rsa.pub | ssh b@B 'cat >> .ssh/authorized_keys'
 b@B's password:

From now on you can log into B as b from A as a without password

a@A:~> ssh b@B

A note from one of our readers: Depending on your version of SSH you might also have to do the following changes:

Put the public key in .ssh/authorized_keys2
Change the permissions of .ssh to 700
Change the permissions of .ssh/authorized_keys2 to 640

 

Summary

1) Run the command below on A and keep type enter while following the prompt:
ssh-keygen -t rsa

2) Create the ~/.ssh on B from A via ssh:
ssh mylogin@B mkdir -p .ssh

3) Append public key from A to B’s ~/.ssh/authorized_keys by running the command below on A:
cat ~/.ssh/id_rsa.pub | ssh mylogin@B 'cat >> .ssh/authorized_keys'

4) Verify:
ssh mylogin@B

Permission:
– ~/.ssh needs to be 700
– .ssh/authorized_key needs to be 640

Linux: How To Use RVM to Manage Ruby

Ruby is a very popular programming language that has Ruby on Rails, or RoR, is a popular development framework that allows you to easily get your application up and running with minimal hassle.

Developing applications often times requires that you emulate different environments. Different versions of Ruby may be necessary for different projects. With conventional installations, this would impede your ability to be flexible.

How To Install Ruby on Rails on Linux Mint 17.3

Ruby on Rails is one of the most popular application stacks for developers wishing to create sites and web apps. The Ruby programming language, coupled with the Rails development framework, makes app development simple.

Since Ruby on Rails doesn’t come in a neatly packaged format, getting the framework installed used to be one of the more difficult parts of getting started. Luckily, tools like rvm, the Ruby Version Manager, have made installation simple.

In this guide, we’ll show how to install rvm on an Linux Mint 17.3, and use it to install a stable version of Ruby and Rails.

iPhone, iPod Touch, iPad and Apple TV on Linux

IPhone on Linux

IPhone on LinuxMany people have claimed that the only thing keeping them attached to Windows is iTunes, so this is for all those people. While researching the steps for jail-breaking an iOS device I stumbled upon what is the equivalent to iTunes for a Linux system. The software seems pretty solid and it runs well from my own trials, although I don’t own an iPhone. The project has been around since 2007 and has turned into a pretty solid piece of software. Go here to download the software and learn more about the project. The setup may seem somewhat intimidating upon first glance, but see page (http://www.libimobiledevice.org) will see that there is not that complicated.

Windows Managers and Desktop Environments in Linux

Gnome 3 - Desktop

Gnome, KDE, XFCE or LXDE. What is the best?

That is a very broad question, so let me try to whittle it down a bit. If you’re coming to Linux for the first time from Windows or Mac, you’re not familiar with the very concept of having different desktops to choose from! The only thing I ever really changed on my Windows desktop was wallpaper and themes. But in Linux, you can choose different window managers and desktop environments.

he two are different things. The window manager controls how the desktop windows are “drawn” by your computer. When we refer to windows in Linux, we don’t mean that other operating system by Microsoft, we mean the little boxes that contain the graphics for whatever application you launch. Microsoft did a smart thing by calling their OS “Windows.” It sort of suggests that they invented the little things. But in fact, long before there was the Windows operating system, there were windows with borders to separate running applications. Unix and DOS both had windows.

In Linux you can choose between window managers like Icewm, Openbox, Fluxbox, and Xfwm. Openbox is a big favorite because it has a nice “right-click anywhere on the desktop” feature that brings up a whole menu from which you can launch applications, open a terminal, etc. You can even have wallpaper. Many folks with older low-powered machines use only a window manager and no desktop environment at all. Without the extra visual “eye candy” and decorations, computers running only a window manager run very fast! Fluxbox is considered a little less “newbie friendly” than Openbox, I’m sure that isn’t the case with our Fluxbox edition. Google the term “Linux window managers screenshots” to see what can be done with just a bare-bones window manager!

A desktop environment on the other hand includes a window manager but also includes stuff like panels, applets, and applications that are designed to work best in that particular desktop environment. Among desktop environments are KDE, Gnome, Xfce, Enlightenment, and LXDE. Each has it’s own special features and applications. The “heavyweight” desktop environments (KDE and Gnome) have all sorts of wonderful features like “plasmoids” and the famous “spinning cube.” They’re more demanding on resources, but on computers 2 years old or newer, they run plenty fast. Xfce is kinda sorta like “Gnome Lite,” if you will. It “feels like” Gnome but offers fewer of the extra fancy features and is designed to work better on modest hardware. LXDE is a very “lightweight” desktop environment – so light in fact that it has been “accused” of being a window manager instead of a full-fledged desktop environment. The look of LXDE reminds alot of people of what “Windows 98” looked like.

Each of the desktop environments has it’s own set of applications that work best in their “native” environment. That is called “integration.” Xfce applications, for example, are integrated into the Xfce desktop environment, so the experience of applications in their “native” desktop environment will tend to be snappier and more responsive. Most people mix-and-match applications anyway. You can use any application in any desktop environment! But if you have limited space on your hard drive, it’s better not to do that, since installing a single KDE application onto a Gnome desktop, for example, may also “pull in” large libraries from the other desktop environment. Here’s are some of the applications listed according to the desktop environment they are native to:

CD Burners:
K3B – KDE
Brasero – Gnome
Xfburn – Xfce

File managers:
Konqueror – KDE
Nautilus – Gnome
Thunar – Xfce
PCManFM – LXDE

Music Players:
Amarok – KDE
Rhythmbox – Gnome
Exaile – Xfce
LXMusic – LXDE

These are just a few examples. The KDE file manager also doubles as a nice web browser! Some find it complicated, others love it. Brasero always just makes coasters out of my blank CDs, but both Xfburn and K3B work flawlessly. Other people find that Brasero works best for them. The only way to be sure is to “use what you have,” and if it doesn’t work or you don’t like it, try one of the others. So much choice! It’s wonderful, but a bit overwhelming to a newbie. So much of it is a matter of taste and what works on your own machine. It took me a year of trying them all to finally choose a favorite (I’m an Xfce fanboy now – but that could change too)! I chose what works fastest on my hardware yet still offers most of the features I want in a desktop.

Now you see why it’s a bigger question than it seems like at first! Sooooo many choices! But don’t hurry! Try a few, one every month or two when you feel like exploring, and if you’re delighted with what you’ve got, just keep it! But it’s fun to see what the others are like. Many a nicely “pimped out” desktop with wicked special effects has won a few people over from Windows and Mac. And many an aging heap has been saved from a landfill and converted into a screamin’ fast machine by a sweet-and-simple, bare-bones window manager! A number of families from the studio where I take dance class have been won over by the mind-bending speed and elegance of a lightweight Xfce mixture on an ancient old dinosaur that was donated for the kids to use.

How to choose?

1. – Look at screenshots from the different DEs and WMs and pick a pretty one!

2. – Consider a “lightweight” if you have an older, low-resource computer that you want to run fast!

3. – Experiment with the different applications from the different DEs and see what works best for you and fits your needs and tastes.

4. – Don’t forget to ask your family if you share the computer with them!

Enjoy the ride. It’s fun to try them all.

How to resize the Unity 2D launcher.

It’s a pretty simple process, just need to edit three files. For those who don’t know Unity-2D uses qt to draw it. So all we need to do is change a few values in the qml files.
Unity-2D lives here: /usr/share/unity-2d. The three files we are going to edit are:
/usr/share/unity-2d/shell/Shell.qml
/usr/share/unity-2d/shell/common/IconTile.qml
/usr/share/unity-2d/shell/launcher/LauncherList.qml

Shell.qml
Find the line that looks like this:
LauncherLoader {
id: launcherLoader
anchors.top: parent.top
anchors.bottom: parent.bottom
width: 65 <– Change this.
I used 50.

IconTile.qml
The first one is optional:
Item {
id: iconTile

property bool activeFocus: false
property bool backgroundFromIcon: true <– set to false to stop the tile from pulling colours from the icon.
property alias source: icon.source
property alias backgroundOpacity: tileBackground.opacity
Then find this:
Image {
id: icon
objectName: “icon”
anchors.centerIn: parent
smooth: true

sourceSize.width: 48 <– I used
sourceSize.height: 48 <– 32.

LauncherList.qml
Find this:
/* The spacing is explicitly set in order to compensate
the space added by selectionOutline and round_corner_54x54.png. */
spacing: -7

property int tileSize: 54 <– controls tile size, I used 40

/* selectionOutline tile size, so AutoScrollingList view can calculate
the right height. */
property int selectionOutlineSize: 65 <– controls spacing, I used 48

That’s it. The rest is fiddling with png’s to get the look you want. For example; The background fill looks bad with a monochrome icon theme, so I hollowed out the background image with gimp. If you want to change the start button it’s in the unity/5 folder it’s called launcher_bfb.png.

Disclaimer:
These are system files your messing with, so be sure to backup the entire directory before you start. Also backup when your done, any unity updates will overwrite your changes. These changes WILL apply to all users. And of course I’m not responsible if you break your system. You can keep the pieces thou
