OpenSUSE is one of the most outstanding operating systems in the world of Linux for being very stable. Its stability and popularity come from being the community distribution of SUSE that is so well positioned. This company collaborates and sponsors many projects related to open source providing professional support. So, I could say that it competes with RHEL or Canonical but with new technologies. Therefore, it is not surprising that it is chosen by many sysadmins as a system where to deploy their applications. In this post, you will learn how to install Nginx on OpenSUSE 15.2

Nginx is one of the most popular Open Source services in the world. It is a web server that stands out for being high-performance and providing an ability to handle many requests on one server. In addition, Nginx has recently been purchased by F5 Networks to continue a growth process.

All in all, it is easy to deduce that OpenSUSE or SUSE are privileged options for running network services. So today I will show you how to install Nginx on OpenSUSE 15.2 or SUSE 15. This way you can enjoy a great web server in a great Linux distribution.

1. Upgrade the system

As always we recommend doing a general update to the system. With this, you will be more stable and ready to start the process.

:~$ sudo zypper up

1.- Upgrade the system

The result will be that your system will have the latest security patches installed. So it will be safer and more protected against cybercrime.

2. Install Nginx on OpenSUSE 15.2

Nginx is available in the OpenSUSE and SUSE repositories. This is a great advantage to increase the ease of installation. On the other hand, we will not always have the latest versions.

So, first, search for Nginx using Zypper.

:~$ sudo zypper search nginx

2.- Nginx related package

As you can see, there are several packages related to Nginx within the official repositories of the distribution. However, the nginx package is the one you need to install the web server.

:~$ sudo zypper in nginx

3.- Install Nginx on OpenSUSE / SUSE

Then, it is a good idea to enable the Nginx service to run as soon as the system starts.

:~$ sudo systemctl enable nginx

After that, start the service.

:~$ sudo systemctl start nginx

If you want to see the status of the Nginx service, you can use the following command:

:~$ sudo sytemctl status nginx

4.- The Nginx service

Now, it is time to test it.

3. Test Nginx on OpenSUSE

The next step is to check that Nginx is running correctly. To do this, you need to make an HTML file and place it in the root directory of Nginx in OpenSUSE / SUSE.

So, use nano to do it.

:~$ sudo nano /srv/www/htdocs/index.html

Add the following:



Welcome to osradar

5.- Test nginx

Save the file and close it.

Then, make some changes to the firewall settings to allow the HTTP service:

:~$ sudo firewall-cmd --add-port=80/tcp --permanent
:~$ sudo firewall-cmd --reload

6.- Firewall settings

Now, open your favorite web browser like Firefox or Chrome and go to http://SERVER_IP/ and you will see this.

7.- Welcome to osradar

So, Nginx is working.

Discovered vulnerability in sudo. Upgrade your system now!

angeloma — Tue, 15 Oct 2019 15:46:15 +0000

One of the great advantages of using open source software is that its code is customizable by anyone. This brings the great advantage that there are many eyes seeing the caught in search of perfecting it. And that’s what happened because thanks to Joe Vennix has discovered a vulnerability in sudo. In this post, we will explain about it and also tell you how to correct it.

Quickly and by way of introduction, I will tell you that sudo is a tool that allows you to execute commands as if you were another user. Usually the other user is the root user. That is to say with our regular user, we can execute commands as if we were root user.

This situation brings many advantages when facilitating usability in a home system, but is not widely used in business.

The detail is that a vulnerability has been discovered that grants permissions of root user to whom it should not.

Specifically we refer to a vulnerability identified with the number CVE-2019-14287 and has already been documented by Canonical under the number USN-4154-1.

In which Ubuntu versions is there a vulnerability in sudo?

For now, the vulnerability in sudo affects the following versions of Ubuntu:

Ubuntu 19.04
Ubuntu 18.04 LTS
Also, Ubuntu 16.04 LTS
Ubuntu 14.04 ESM
Ubuntu 12.04 ESM

This at server level as well as desktop operating system level. Therefore, as Ubuntu is one of the most popular distributions, it is easy to deduce that many people are affected by the vulnerability.

On the other hand, also versions 17.x, 18.x and 19.x of Linux Mint has been affected. This is because Linux Mint uses Ubuntu’s base packages for the system.

What was the problem?

The /etc/sudoers file is where you find the configuration of which users may or may not use the sudo command.

However, the security breach discovered allowed any user to use commands as root. This was accomplished by modifying the file to circumvent the ban. That is, even when it was defined that a user could not execute sudo, modifying the sudoers file and setting user ID -1, this policy is circumvented.

On the other hand, it is worth mentioning that sudo is not enabled on many servers and there the consequences are less serious.

How can I solve the problem?

Fortunately, the vulnerability has been discovered and patched. Therefore, at this point it should already be available as an update through your preferred package manager.

For example, in the case of Ubuntu and Linux Mint is already available.

Upgrade your system to resolve the vulnerability in sudo

And so on the rest of the Linux distributions. Just upgrade. In case you do not have the new update, wait a little longer and it will surely be available.

Sudo has been compromised but there is already a solution. Upgrade now!

Also, you can learn how to enable on Debian and CentOS.

angeloma — Sat, 30 Mar 2019 19:00:14 +0000

The Kernel Linux is one of the most important elements of the system. Because it is in charge of the interaction with the hardware. Recently we were talking about the new version of the Linux Kernel which is version 5. For many people, it is important to have the kernel updated for hardware issues others will prefer the tranquility of a stable system. If you are one of the first and use OpenSUSE 15 is your lucky day. In this article, we will show you how to install the Linux Kernel 5 on OpenSUSE 15.

A new version of the Linux kernel was recently released. Although this new version is not a revolution at the program level, it has some interesting new features. These new features are better implemented in recent hardware.

So, let us start.

Install the Linux Kernel 5 on OpenSUSE 15

One of the great advantages of using OpenSUSE 15 is that it has a large list of repositories maintained by the community. These repositories make maintaining certain system components quite simple. For example, there is one for KDE Plasma or for web development.

So the first thing to do is to open a terminal emulator and add the Kernel repository in OpenSUSE.

:~$ sudo zypper ar -f http://download.opensuse.org/repositories/Kernel:/stable/standard kernel:stable

1.- Add the kernel repository

Then, we will be asked for the password of our user and then the confirmation of the operation. Being a repository sponsored by OpenSUSE is quite secure and will add the GPG key.

Now, it is necessary to tell the distribution that there is going to be an update of that single repository so that it does not affect the rest of the system. So to do this, run the following command:

:~$ sudo zypper dup -r kernel:stable

2.- Install the Linux Kernel 5 on OpenSUSE 15

Note: in case you have any repository problems, just install the packages manually by running

:~$ sudo zypper in kernel-default-5.0.5-1.1.g0fb0b14

Now, you have to wait for the process to finish and then restart the system.

When the system has started, verify the new kernel using the following command:

:~$ uname -r

3.- The Linux Kernel 5 On OpenSUSE 15

Conclusion

As we can see, installing Kernel 5 on OpenSUSE is not a complicated matter. However, it can help many users to make their very recent hardware benefit from the many new features of this new version.

4.- Add the Jenkins official repository

Next, install Jenkins.

:~$ sudo zypper install jenkins

5.- Trust in the repository

6.- Install Jenkins on OpenSUSE and SUSE 15

Now, start the service and check the status.

:~$ sudo systemctl start jenkins
:~$ sudo systemctl status jenkins

7.- Start Jenkins

Jenkins uses the 8080 port. So, set the Firewall rule to make Jenkins available.

:~$ firewall-cmd --zone=public --add-port=8080/tcp --permanent
:~$ firewall-cmd --zone=public --add-service=http --permanent
:~$ firewall-cmd --reload

8.- Creating a new firewall rule for Jenkins

Next, get the admin password.

:~$ sudo more /var/lib/jenkins/secrets/initialAdminPassword

9.- Showing the initial admin password

The next step is open your web browser and go to http://IP_SERVER:8080. And put your password on the field.

10.- Jenkins initial screen

Then you will be asked about the plugins to install. Choose the recommended plugins. Then, the installer wll start the work.

11.- Starting the installation on the web interface

Next, create the admin account.

12.- Creating first admin user

And that’s it. Jenkins is installed. Finally, you will see the dashboard.

13.- Jenkins is ready

14.-Jenkins dashboard

Conclusion

As you can see, the installation of Jenkins in the SUSE ecosystem is not difficult. On the contrary, there is a repository that makes everything simple. Jenkins is an application that every sysadmin should use for the automation and deployment of software projects.

Suse Sold for $2.5 Billion

osradar_editor — Wed, 04 Jul 2018 07:15:13 +0000

Suse is one of the longest-running commercial Linux distros. At present, Suse also plays a really important role in the infrastructure of the open-source software. In fact, Suse has become a major player in the field. For any company, the ownership change is a part of its life cycle and Suse is no different. We’ve already seen several ownership changes for Suse. The latest change took place very recently. Micro Focus, the last owner of Suse, announced that the ownership is going to be handed over to EQT – a private equity firm and venture capital fund.

Suse past

Novell, the past owner of Suse, handed over the ownership to The Attachment Group in 2010. Then, Micro Focus owned Suse back in 2014 from The Attachment Group. Now, EQT is going to take over Suse for $2.535 billion.

In the field of open-source software, Suse passionately engaged with tons of projects and helped the community a lot. The contribution is not a joke.

So, this might be a question – why Micro Focus sold Suse? The answer is obvious (sort of). Despite Suse managed to live and grow further under the umbrella of Micro Focus, there were some major patches that Micro Focus faced during the course of its business. The major disappointment was acquiring Hewlett Packard Enterprise back in 2016 for $8.8 billion that didn’t get any major success. It’s natural to assume that for coping with their situation, they decided to sell off Suse.

About EQT

The current owner of Suse is an interesting one, to be honest. The firm doesn’t have too much popularity. The portfolio of the farm also includes other tech companies and most of them are unheard of before.

Redhat vs Suse who is successful

Mel K — Wed, 27 Dec 2017 12:08:33 +0000

Software which are open sources were used to be rare until Linux make it successful and launch a platform which was open source providing opportunities to people to contribute their parts.

The 25-years of age working framework has developed so quick. Today, it is utilized all over the place. From Internet of things based devices to super conductors, its applications can be found everywhere. Linux turned out to be something beyond a working framework to run some lab servers. What’s more, along these lines, it made enormous open doors for endeavors to profit by. This market permitted incredible technology based organizations to be set up to satisfy its needs. It gave us three major Linux platforms which are Red Hat, SUSE and Canonical.

Red Hat

Red Hat was launched in 1993 and after its establishment it developed so fast and now it is considered to be the biggest Linux open source platform and is playing a key role in the world of open source applications. Red Hat has given a lot of solutions to offered a lot of services. Red Hat Enterprise Linux, is genuinely made for its own distribution for organizations. Simkilarly, Red Hat open stack which is a stage for conveying and scaling open and private mists. Also, Open Shift, which is a solid platform providing answers to set up web based applications (programmed in Python, Node) as an independent contained stage. Red Hat likewise gives administration arrangements, for example, Red Hat Cloud forms.

Red Hat gives significantly more items and advantages than any other platform. Red Hat recognition and certificate is considered very important in the Linux world. In the event that you are wanting to get a job in this field, you unquestionably would go for RHCSA or RHCE. As indicated by Red Hat2), over 90% of the main 500 fortune worldwide organizations depend on them for their framework. This biological system of advances, accreditations and administrations is the primary speculation for Red Hat.

Following is given a complete list of Red Hat offers.

Red Hat likewise has a ton of commitments to a great deal of other free and open source programming. Indeed, even programming which isn’t possessed by it.
With various around 10000 workers in the world), Red Hat’s 2016 monetary year (finished in February 29, 2016) showed4) an income of $2.05 billion. A net benefit of around $200 million and $716 million in working money, and aggregate resources of $4.155 billion.

Similarly, Red Hat’s most recent report about the second from last quarter comes about for financial year 2017 (finished December 21, 2016) an income of $615 million. The organization is expecting an aggregate income of around $2.4 billion for the monetary year 2017 . In this manner, making it – decently – the biggest open source organization on the planet.

SUSE

SUSE is also known as the great Lizard of Linux as shown by its figure.

SUSE is also an exceptionally famous and well known organization in the Linux world. When it was established in 1992, it was the principal organization to utilize Linux for focusing on undertakings purposes. In those days, SUSE was an independent organization, however in 2003, it was procured by Novel. Which was likewise obtained by a group of companies called Attachmate in 2012. At last, MicroFocus procured Attachmate in 2014. In this way, SUSE turned into an auxiliary of the MicroFocus organizations .

With few 750 representatives of SUSE around the world. SUSE made $253.8 million in the financial year finished 30 April, 2016-17). According to a report which was released in October 8,2016, SUSE made $147.4 million. An expansion of 23.3% of the past between time in 2015 for a similar period which was $121.2 million.These outcomes put SUSE as the second player in the open source world after Red Hat. SUSE is likewise a key player in building up a great deal of other free and open source programming, which would bee be able to seen from their site.
