In the next article we are going to take a look at Teleconsole. This is a free service to share our terminal session with people we trust. Your contacts can join through the command line using SSH or through your web browser using HTTPS. This service is very interesting to ask for help. We will also be able to forward local TCP ports to your contacts. Use this feature to allow them to access web applications that run on your local server. You may already know the popular remote desktop applications that are available on the market, such as Teamviewer, Skype, Join.me, Chrome Remote Desktop, Real VNC, Apache Guacamole, etc. These are used to share the whole system, but in some situations it may be of interest to share only our terminal session quickly. Due to a situation like the one described, teleconsole and tmate were born. Teleconsole is built on Gravitational Teleport. This is a modern SSH server to remotely access clusters of Gnu / Linux servers through SSH or HTTPS. It is an...

The repositories of Ubuntu are being the center of the controversy of Ubuntu during the last months. After the serious error that appeared in the wake of the Ubuntu 17.10 kernel, appeared the error of Specter and Meltdown. An error that made Ubuntu have to remove the latest versions of Intel's microcode in order to give stability and security to the distribution. Over time, Intel has managed to create a safe driver or microcode for Ubuntu and that is why Ubuntu decided to work with it to offer a secure update for all platforms of Ubuntu users. So far, the solution was only on 64-bit platforms. Days after the release of that update, we can say that the security update is available for all Ubuntu architectures, especially for the 32-bit platform, a platform that many users still use (although many Ubuntu developers do not create it) and that at the moment was unprotected against these security bugs that allowed the appropriation of the machine through the kernel. This update wil...

In the next article we are going to take a look at Zeal. This is a tool that will provide us with an offline documentation browser for software developers. Zeal is inspired by Dash, which is a commercial application developed especially for Mac OS. Zeal provides documentation sets (docsets) for a large number of programming languages ​​and different software. You can read them all, online or by downloading the documentation to your team. This will allow any developer to find everything they need without having to search Google or check the official documentation page. You just have to download the set of documentation that we want to use. Zeal will take care of everything else. At the time that I am writing this article, there are 192 sets of useful documentation for all kinds of developers. You can consult the languages ​​available in the following screenshot. All those documents are generously provided by Dash. These documents are updated and maintained with great care. Bu...

In this article we will take a look at Nitrux, this distribution of Linux based on Ubuntu with an excellent design and I bet that more than one will give you the desire to try it. Nitrux comes with its Nomad desktop environment which is built on KDE Plasma 5 and QT, Nomad takes the best of this environment to present a visually appealing desktop, which personally reminds me a lot of Pantheon. The distribution also takes some KDE applications and makes use of the application appimage format with which it happens to differ a lot from other distributions based on Ubuntu. This is the interesting thing about Nitrux, because its developers venture to offer the user something new and that without doubts from my perspective and many distributions should begin to offer. Nomad Desktop The Nomad desktop improves the user experience, since it includes other additional functions which make it more functional, since its objective is to be adaptable without losing its aesthetics or functionali...

Martin Wimpress, the leader of the Ubuntu MATE project, has presented the new interface of Ubuntu MATE. An interface that has been baptized as "Familiar" and that will be present in versions superior to Ubuntu MATE 18.04 and in versions that have MATE 1.20 or higher. This new interface of MATE is minimalist, reducing the number of menus and retaking the quick menu that in other versions of Ubuntu MATE was present. Familiar is a new interface that replaces the traditional MATE panel with a quick menu and several direct access applets. Being a more functional and usable option for many users. Although we must also say that with it, Ubuntu MATE stops having the appearance of Gnome 2 that so much like the most traditional users. Now, this new interface of MATE can be changed by other interfaces like Muttiny itself, the interface that resembles the old Unity desktop. In addition to the new interface, Ubuntu MATE 18.04 will bring a bug fix in Ubuntu Boutique and Ubuntu Welcome, ...

Mozilla is preparing a new version of Mozilla Thunderbird. This new version will not be a version but a great version similar to Firefox Quantum in his older brother, Mozilla Firefox. This version is called Mozilla Thunderbird 60. A version that does not have major changes in the engine or application core but that will have great news and changes compared to other versions. At least that is how it can be seen in the beta version that has recently appeared on the Mozilla development channel. As we say in the title, Mozilla Thunderbird 60 will finally have a calendar next to the email client. I know that everyone who used and used Thunderbird can have a calendar, but it was not part of the email client but a complement called Lightning that was previously given the possibility to choose to install it and in the latest versions it was installed by default, but it was not part of the client. Now not only the calendar will be part of the client but it will be able to interact with the ma...

This time I will take advantage of you to share this openSUSE installation guide, to be specific to your Tumbleweed version. This version, in comparison to the others offered by openSUSE, is a Rolling Release version. In this case I decided to install openSUSE Tumbleweed because it is boring and tiresome to have to update a system every time there is a new version, that's why I like the systems more relaying. For those who do not know this model, I will tell you a little, the rolling reads this is always in continuous development as it refers to a software system in constant development, we will always have the latest but stable. Without more, we will start with the installation process, there are many people who think that the system is intended for advanced users, when it is not, for those who are new to Linux they should only do their part and have patience. Just a comment, if you are not completely sure of what you are going to do, I recommend you first use a virtual m...

No doubt CentOS is the operating system that usually occupy most of the web servers, it is a very robust and highly configurable system. This has been proven by me since in almost all dedicated server providers I have found CentOS as the default system. That is why I made the decision before purchasing a dedicated server, knowing a little more about the CentOS system as well as some tools and functions that I have drawn attention to. CentOS Installation Guide 7 To begin with the installation of the system, the first step is to download the system, for this we must go to the official website and download the image of the system, in my case I obtained the minimum version, since I require it for web server. Now it is essential to know the requirements of the system, since in my case I occupy only the minimum version I require: 1 ghz processor 64MB RAM 1GB disk space Internet connectivity Otherwise if you are going to have to use the system with graphical environment the requir...

There is no doubt that the security of information in the network is paramount, we are increasingly knowing cases where hackers manage to create a new method to violate the security measures implemented in various computer systems. Since the famous case in which the Movistar company suffered an attack, there have been cases of the same type, but with variants of the attack. If something I strongly agree with is that no matter how safe a system is, if it is through the human factor, it is the gap to enter. And why do I say this, since it is simple, many of the attackers take advantage of human error to obtain the information they want and that is from a simple exploit, if the victim does not have the slightest idea of ​​how to differentiate between a real site to a fake, it's just lost. A very simple way to protect your information, even if you fall into fake sites, is using two-step authentication. This method works in the following way: to enter a site you require a user and a...

Yesterday, the immediate availability of the Fedora 28 beta was announced, the next version of this magnificent Linux distribution. Initially expected by the end of March, Fedora 28 Beta is now available for public testing, bringing with it many of the latest versions of free software and GNU / Linux tools, among which we can mention the GNOME 3.28 environment and a new modular repository for Fedora 28 Server.

Additionally, Fedora 28 Server supports architecture AArch64 (ARM 64) as primary architecture.  "Instead of a separate modular operating system, we have added a modular repository next to the common repository. With the Fedora Server edition the modular repository will be available immediately. You will have access to some modules today and will arrive mo...
