Now, lets simulate one attack and see the result. Open your browser and put your_ip into address bar with port 80 and press enter key or go button: 
your_ip:90
Take a look to your terminal and see the result. You can see something like that:

Ubuntu Snap now universal coming to Linux distros like Fedora Arch OpenSUSE and more!

Ubuntu Snap now universal coming to Linux distros like Fedora Arch OpenSUSE and more!


 
My biggest complaint about Linux based desktop operating systems is fragmentation. There are too many desktop environments, too many package managers, heck, too many distros! Not only can end-users be negatively impacted by too many choices, but more importantly, developers can be spread too thin. Ultimately, the Linux community ends up being unfocused and unable to move the desktop dial.
 
Today, something miraculous happens. Believe it or not, the Linux Community largely bands together to embrace Ubuntus "Snap" packages. Yes, you are reading that correctly -- competing Linux-based operating systems like Fedora, Gentoo, Arch, and more, will utilize the now-universal "Snap," meaning Linux software can be made to install regardless of distro. This should be particularly brilliant for operating systems optimized for mobile and IoT.
 
"Snaps sit alongside the native packages of the base Linux operating system. Each distribution has its own mechanisms to provide the base OS and its updates. Snaps complement the base OS with universal apps that cannot interfere with the base OS or one another", says Canonical.
 
The company further says, "the snap format is simpler than the native internal package formats of individual Linux distributions, because it is focused purely on applications rather than the core system itself. Snaps are essentially self-contained zip files that can be executed very fast in place, making them easy to create".
 
Canonical shares the following Linux-based operating systems which can now natively work with Snaps.
  • Arch
  • Debian
  • Fedora
  • Kubuntu
  • Lubuntu
  • Ubuntu GNOME
  • Ubuntu Kylin
  • Ubuntu MATE
  • Ubuntu Unity
  • Xubuntu
Snaps are being validated to work in the future on the following distros.
  • CentOS
  • Elementary
  • Gentoo
  • Mint
  • OpenSUSE
  • OpenWrt
  • RHEL
Mark this date on your calendar, Linux fans. By simply porting snapd to the distro, the Snaps can be installed without worry. This is revolutionary, and will change the way both developers and end-users deal with packages. The container-like design should prove more secure too.
 
 
Jason Shepherd, Director, IoT Strategy and Partnerships, Dell says, "we believe snaps address the security risks and manageability challenges associated with deploying and running multiple third party applications on a single IoT Gateway. This trusted and universal app format is essential for Dell, our IoT Solutions Partners and commercial customers to build a scalable, IT-ready, and vibrant ecosystem of IoT applications".
 
If you are a developer and you want to create a Snap, you can do so here. If you need some assistance, you can reach out on IRC here.
 
Do you think the universal acceptance of Snaps is a game-changer? Tell me in the comments.

Tutorial How to Disable SELinux in Fedora 17

Tutorial How to Disable SELinux in Fedora 17


What is SELinux? SELinux is linux variant that implements a many security policies through the use Linux Security Modules (LSM) in Linux Kernel.

For security server, SELinux is most suitable option to secure server, because efficacy and complexity. But for desktop computer, I think SELinux it is less suitable to be applied, because too complicated and difficult. To access everything becomes difficult because it is restricted by SELinux.
So in this article will explain how to disable SELinux on Fedora 17:
  1. Run the Terminal and go to superuser with type: sudo su
  2. Edit file /etc/selinux/config using gedit with type this command in Terminal:
    gedit /etc/selinux/config
  3. Then look for the word: SELINUX=enforcing
  4. Replace word: enforcing become disabled
  5. Then save by pressing Ctrl+S
  6. Close gedit.
  7. SELinux has been disabled.
