More Information

To find out more information about the SUSE OpenStack Cloud 9 beta program please have a look at the blog from our beta manager Vincent Moutoussamy. Blog on Details of Cloud 9 Beta

Also, here is the link to the Cloud 9 beta webpage that provides the instructions on how to participate in the beta program. https://www.suse.com/betaprogram/cloud-beta

Have you every wondered where the term “On Cloud Nine” came from? This came from the US Weather Bureau in the 1950s, in which “Cloud Nine” signifies cumulonimbus type clouds that so attractive. The definition is a state of perfect happiness or bliss. Please give Cloud 9 from SUSE a test ride and I hope you achieve happiness.

What are the Things to Do After Elementary OS Juno Installation

Elementary Juno Things to Do

Here comes Elementary OS 5 Juno which is built with ultimate care for better user experience. This time it comes with Linux 4.15 (based on Ubuntu 18.04 LTS) which brings improved hardware support and performance. Read the official release announcement and know about the added features in details.

If you already downloaded & installed elementary Juno then I will show things to do after installing elementary OS Juno for better user experience.

Things to do after installing elementary OS Juno

1) System Update

Open the command line by clicking Applications in upper left portion of the screen, and click Terminal.
To permanently become root user, type sudo su – and enter user password you specified during installation.

$ sudo su –
[sudo] password for linoxide:
[email protected]:~#

To get a list of all packages that should be updated, enter the following command

# apt-get update
Now to do the actual update, enter
# apt-get upgrade

After you accept (‘y’) the installation, it will take a while, depending on how many packages are there to be updated.

2) Gnome Tweak

Gnome tweak is a software that you can use to customize your Gnome Desktop environment such as the icons, theme, cursor theme and many other things.

# apt-get install gnome-tweaks

3) Enable tap to click for laptop users

Some Linux systems disable the tap to click so you will need to enable it in order to use it. You can enable it by going to Applications -> system settings -> Mouse & Touchpad.

4) Enable Night light

The night light feature adapts the display settings based on your location and the time of the day which reduces the amount of blue light emitted in the evenings. You can enable it by going to Applications -> system settings -> Displays. The schedule is automatic but you can set it manually

5) Configure Networking

The easiest way is through GUI-click the icon of the network in top right portion of the screen.

Click Network Settings, choose Ethernet and Edit Connections. Select Wired Connection 1 and click the tool icon

Now in IPv4 tab, enter “Manual” instead of “DHCP”, and fill in the fields for address, subnet mask, gateway, and DNS server accordingly.

6) Remote Access via SSH

To remotely connect to your server via SSH, you need to install an SSH server on your Elementary OS virtual machine.

# apt-get install openssh-server

7) LibreOffice

For a free Office alternative, install libreOffice.

# apt-get install libreoffice

After a quite lengthy installation, you will get new icons in Applications for LibreOffice Base, Cals, Draw and its other application.

8) VLC Player

The fabulous VLC player is easy to install with:

# apt-get install vlc

9) Amarok

Some people prefer to play music with Amarok music player, and it can be installed with

# apt-get install amarok

10) Audacity

One of the best audio recording and editing software on Linux is Audacity.

# apt-get install audacity

11) Thunderbird

My personal preference for mail clients on Linux as well as on Windows, Mozilla Thunderbird is available for install as well.

# apt-get install thunderbird

12) Firefox

For those of you who like Firefox web browser:

# apt-get install firefox

13) GIMP

Not really a Photoshop, but this is a fabulous graphic editing tool

# apt-get install gimp

14) FileZilla

If you need to access remote FTP connections, most of the people would recommend Filezilla.

# apt-get install filezilla

15) Skype

Skype is not available from default repositories, you need to download the installation package (.deb file) from the official download page.

# wget https://go.skype.com/skypeforlinux-64.deb

# dpkg -i skypeforlinux-64.deb

If you get errors about dependencies, and you probably will execute the following command:

# apt install -f

16) Submission Client

For great torrent client called Submission, execute:

# apt-get install transmission

17) Dropbox

For this great shared storage, go to the dropbox download page

Copy the link and download the .deb package using wget

# wget
https://www.dropbox.com/download?dl=packages/ubuntu/dropbox_2015.10.28_amd64.deb

After you most likely encountered errors, execute the following:

# apt install -f

18) GDebi

Gdebi is a tool for installation of .deb files with automatic installation of dependencies.

# apt-get install gdebi

19) Chrome

We will use gdebi to install Google Chrome. I assume you have already installed gdebi as mentioned in the above steps.

Go to Google chrome download page and download .deb file. By default, file will go to the “Downloads” folder.

# gdebi google-chrome-stable_current_amd64.deb

20) Archive/Compression Tools

The following command will install all major archive and compression tools.

# apt-get install rar unrar cabextract lzip lunzip arj unace p7zip-rar p7zip

21) Java

You will need Java JDK for many things, so you can install it with:

# apt-get install openjdk-8-jdk

22) Video Processing Codecs

If you are going to process videos, you need codecs:

# apt-get install libavcodec-extra ffmpeg

23) Blender

You can install Blender, used for animation and 3D modeling as well

# add-apt-repository “deb http://repository.spotify.com stable non-free”
# apt-get install spotify-client

29) Wine

If all these programs do not satisfy your needs, and you still need a Windows version of some program, you can install Wine, which lets you run native Windows programs under Elementary OS.

Luckily, Wine is already installed on Elementary OS.

30) Install Atom

Atom is an advanced open source text and source code editor useful for programmers. It is built on Electron and developed by GitHub You can install the latest stable release

# wget https://github.com/atom/atom/releases/download/v1.30.0/atom-amd64.deb

Ubuntu Linux 18.10 Cosmic Cuttlefish is finally available for download!

There has never been a better time to be a Linux enthusiast. There are so many great distributions from which to choose, including elementary OS 5 Juno, Linux Mint 19, and Bodhi 5.0.0. What do those aforementioned operating systems have in common? They are based on Ubuntu. To take things a step further, Canonical’s operating system is based on Debian, but I digress.

But yeah, Ubuntu is wildly popular — with both end users and other Linux distro maintainers. When a new version of the operating system is released, the world goes wild. Well, it’s time to get excited, yall! Today — after a short Beta period — Ubuntu Linux 18.10 Cosmic Cuttlefish is finally available for download!

“Codenamed ‘Cosmic Cuttlefish,’ 18.10 continues Ubuntu’s proud tradition of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution. The team has been hard at work through this cycle, introducing new features and fixing bugs,” says Adam Conrad, Software Engineer, Canonical.

Conrad further says, “The Ubuntu kernel has been updated to the 4.18 based Linux kernel, our default toolchain has moved to gcc 8.2 with glibc 2.28, and we’ve also updated to openssl 1.1.1 and gnutls 3.6.4 with TLS1.3 support. Ubuntu Desktop 18.04 LTS brings a fresh look with the community-driven Yaru theme replacing our long-serving Ambiance and Radiance themes. We are shipping the latest GNOME 3.30, Firefox 63, LibreOffice 6.1.2, and many others.”

Sadly, according to the release notes, there are some known issues as listed below.

  • After installing Cosmic alongside Cosmic, the resized filesystem is corrupted (bug 1798562) It has not been reported to happen if the original operating system is something else than Cosmic.
  • When Ubuntu is reinstalled with preserving existing data, an error message is displayed due to “Could not get lock /target/var/cache/apt/archives/lock” (bug 1798369). The packages installed originally are not reinstalled and must be reinstalled manually. Although the user data is preserved.
  • The screen reader doesn’t read the installer when executed from a live session (bug 1797861), is not auto-enabled on first login even if it’s been enabled during installation (bug 1796275) and the pages of the first run wizard are not read properly (bug 1797868)
  • When disconnecting from VPNs, DNS resolution may become broken requiring a restart of resolved. $ sudo systemctl restart systemd-resolved.service Bug 1797415
  • In an OEM installation, during user setup, the language selected is not taken into account (bug 1798554)
  • The gnome-initial-setup Quit option from the application menu in the top bar doesn’t quit the application. If you want to quit g-i-s use quit from the dock menu instead.

Ubuntu 18.10 “Cosmic Cuttlefish” Due Out Today, Arm Launches IoT-Focused Mbed Linux, GitHub’s New Security Features, MongoDB Announces New Server Side License and Google to Charge for Apps on Android Handsets Sold in Europe

News briefs for October 18, 2018.

Ubuntu 18.10 “Cosmic Cuttlefish” expected to be released today. According to Phoronix, the
biggest change for users will be the revised default theme for the GNOME
Shell experience, now known as “Yaru”. Ubuntu 18.10 will also have the Linux
4.18 kernel, “which means better hardware support, various performance
improvements, and other optimizations compared to Ubuntu 18.04’s Linux 4.15”.

Arm launches the IoT-focused Mbed Linux OS and also extends Pelion IoT
Platform services. According to Linux.com,
Mbed Linux “combines the Linux kernel with tools and recipes from the
Intel-backed Yocto Project. The distro also integrates security and IoT
connectivity code from its open source Mbed RTOS”. In addition, the Pelion
IoT Platform “will align
with Intel’s Secure Device Onboard (SDO) provisioning technology to make
it easier for IoT vendors and customers to onboard both x86 and Arm-based
devices using a common Pelion platform. Arm also announced Pelion related
partnerships with myDevices and Arduino.”

GitHub updated its platform this week, which included many developer-centric
changes and security features, but the most notable change is the
“expansion of the Security Alerts feature, which also now supports Java and
.NET projects, on top of the original JavaScript, Ruby and Python”, ZDNet
reports.

MongoDB
recently announced it will be released under the new Server Side
Public License: “The SSPL clarifies the conditions for making MongoDB
publicly available as a service, to ensure we can continue to invest in
building MongoDB for our users rather than in costly litigation over
enforcing the AGPL. All subsequent versions and patch releases to prior
versions of MongoDB made after October 16th, 2018 will be issued under the
new SSPL.”

Google plans to charge smartphone makers to pre-install apps like Gmail
and YouTube on Android handsets sold in Europe. The
Verge quotes Android leader Hiroshi Lockheimer, “Since the
pre-installation of Google Search and Chrome together with our other apps
helped us fund the development and free distribution of Android, we will
introduce a new paid licensing agreement for smartphones and tablets shipped
into the [European Economic Area].”

SSH Authentication Bug Opens Door If You Say You’re Logged-In

Another security vulnerability can be put in the “found and fixed” category. “Fixed,” that is, if vulnerable servers apply the patch. The good news is that most servers aren’t going to be affected, which narrows the problem down to mere thousands. It could have been much worse.

The problem was with libssh, the popular library for supporting the Secure Shell (SSH) authentication protocol, which due to a coding error would believe anyone who told it their login had already been authenticated and open the access door wide.

Technically speaking, the libssh SSH authentication process is usually started with the message “SSH2_MSG_USERAUTH_REQUEST”, but if sent “SSH2_MSG_USERAUTH_SUCCESS” instead, the server would take this as all the proof it needed that the user had already successfully been authenticated.

The bug, officially CVE-2018-10933, was discovered by Peter Winter-Smith, a researcher at security firm NCC, who then reported it to libssh developers. The devs pushed out versions 0.8.4 and 0.7.6 to address the issue last Tuesday, as well as patches for older versions.

Only server installations need to be patched, as client installs are not vulnerable.

This could have had a nasty ending. The vulnerability had been present since the release of version 0.6.0, which was released in January 2014, but evidently escaped being discovered by the black hats. The potential scope of the exploit was reduced because most servers, IoT devices, and personal computers use the openssh library instead of libssh to implement SSH.

The latter does much to limit the scope of this exploit. According to Amit Serper, who is head of security research at Cybereason, the vulnerability affects a minimum of 3,000 servers (up to about 6,000), but those numbers are only a drop in the serverland bucket.

It could have also been much worse had GitHub, which uses libssh, been affected. Fortunately, GitHub has customized its implementation and doesn’t use the SSH2_MSG_USERAUTH_SUCCESS message.

“Patches have been applied out of an abundance of caution,” GitHub security said in a tweet, “but GHE was never vulnerable to CVE-2018-10933.”

If they had been vulnerable, attackers could have gained access to its customers source code, which includes the code from some of the largest development houses in the world.

Linux Top 3: Fedora 25, openSUSE 42.2 and Zorin OS 12

November 28, 2016
By Sean Michael Kerner

This is the time of year when Linux distribution releases start to slow down (just a bit), but there have been several noteworthy recent releases to recognize before 2017 starts.

1) Fedora 25

Red Hat’s community Linux project Fedora releases Fedora 25 on November 22, providing the second milestone update for 2016. Among the big features is full support for the Wayland display server, which finally replaces the decades old X11 system.

“Wayland has been under development for several years and seeks to provide a smoother, richer experience for graphical environments and better capabilities for modern graphics hardware,” Matthew Miller, Fedora Project Leader wrote in his mailing list announcement message. “To further enhance ease-of-use, Fedora 25 Workstation also features GNOME 3.22, which offers multiple file renaming, a redesigned keyboard settings tool and additional user interface improvements.”

2) openSUSE 42.2

While Fedora continues to act as a sort of proving ground (they don’t like calling it a ‘beta’) for features that often end up in Red Hat Enterprise Linux (RHEL), SUSE is taking a very different approach with its openSUSE Leap distribution.

With Leap, ideas and technologies already proven in SUSE Linux Enterprise come to the freely available openSUSE 42 distribution. The openSUSE 42.2 Leap release debuted on November 16.

Leap is made to give stability-minded users and conservative technology adopters peace of mind. openSUSE Leap 42.2 is powered by the Linux 4.4 Long-Term-Support (LTS) kernel and is a secure, stable and reliable server operating system for deploying IT services in physical, virtual or cloud environments.

A selective process of including well-established packages in openSUSE Leap 42.2 gives new meaning to the term Linux Optimization; openSUSE Leap is simply the safe choice that offers Linux professionals a user-friendly desktop and a feature-rich server environment.

3) Zorin OS 12

Unlike Fedora and openSUSE which are both backed by large vendors, Zorin is a smaller operation, but it’s still trying to generate revenues. Zorin Core is freely available, while the Ultimate edition, which adds games and support is a paid commercial release. The new Zorin OS 12 distribution became generally available on November 18.

At the core of Zorin is the Zorin Desktop Environment which is based on Gnome Shell.

With the new Zorin Desktop 2.0 environment comes a fresh new look. The dark tones of the interface shell create a contrast against the app windows to give a clear distinction between the system UI and the work you’re focusing on.

what is the difference between zabbix passive checks & active checks ?

Zabbix agents support both passive (polling) and active checks (trapping). Zabbix may perform checks based on an interval, however, it is also possible to schedule specific times for item polling.

Passive checks (polling):

  • Zabbix server (or proxy) requests a value from Zabbix agent
  • Agent processes the request and returns the value to Zabbix server (or proxy)

Zabbix server or proxy asks for some data (for example, CPU load) and Zabbix agent sends back the result to the server.

Example: agent ping

  1. Server opens a TCP connection
  2. Server sends agent.pingn
  3. Agent reads the request and response with <HEADER><DATALEN>1
  4. Server processes data to get the value, ‘1’ in our case
  5. TCP connection is closed

Active checks (trapping):

  • Zabbix agent requests from Zabbix server (or proxy) a list of active checks
  • Agent sends the results in periodically

Active checks require more complex processing. The agent must first retrieve from the server(s) a list of items for independent processing.

For example:

  1. Agent opens a TCP connection
  2. Agent asks for the list of checks
  3. Server responds with a list of items (item key, delay)
  4. Agent parses the response
  5. TCP connection is closed
  6. Agent starts periodical collection of data

Zabbix Trapper

Trapper items accept incoming data instead of querying for it.It is useful for any data you might want to “push” into Zabbix.

To use a trapper item you must:

  1. have a trapper item set up in Zabbix
  2. send in the data into Zabbix(with zabbix_sender)
