  • How to install the noip2 on Ubuntu and run via systemd systemctl (noIP Dynamic Update Client) – blackMORE Ops

    Often I find instructions from different vendors that are too generic and doesn’t really work the way you want it to. For example, I use https://www.noip.com for my Dynamic DNS updates and I found that the instructions for installing noip2 Dynamic Update Client is lacking clarity and no fit for purpose in latest Ubuntu servers. Ideally noip2 Dynamic DNS Update Client should continually checks for IP address changes in the background and automatically updates the DNS at No-IP whenever it changes. But the instructions are lacking as if you reboot your server, it doesn’t work anymore because it doesn’t run on startup. This post attempts to fix that problem by installing required packages to run the make command, install noip2 binary, fix file permissions if missing, create an init.d script for service command, create a systemd file so that we can control it via systemd and finally enable it via systemctl. I know, I know I overdid it but it doesn’t hurt and now you will have multiple ways to control it. If you’re familiar with it then you can skip parts to get to the right sections to either use init.d or systemd, so feel free. Now let’s get to it...

Getting started with btrfs for Linux [Former headline: Forget ZFS and use Btrfs]

Filed under
Linux
HowTos

Btrfs has been available for Linux for several years, so you may already be familiar with it. If not, you may have questions about it, especially if you use Fedora Workstation (Btrfs is now its default filesystem). This article aims to help you get familiar with it and its advanced features, such as copy-on-write and checksums.

Btrfs, short for B-Tree Filesystem, is actually a filesystem and volume manager rolled into one. It's often seen as a response to ZFS, introduced in Sun Microsystem's Solaris OS back in 2005, now largely replaced by an open source implementation called OpenZFS. Ubuntu Linux and FreeBSD often feature OpenZFS. Other examples with similar features are Red Hat's Stratis and the Linux Logical Volume Manager (LVM).

[...]

Btrfs offers a lot of promise for delivering an advanced filesystem feature set to Linux. It wasn't the first; I credit ZFS for my introduction to this type of filesystem some 15 years ago, but Btrfs is fully open source and unencumbered by patents.

I advise starting with a virtual machine or spare system if you want to explore this filesystem.

I would like to see some graphical management utilities produced for system administrators who like to operate in the GUI world. Fortunately, Btrfs has strong development activity, as evidenced by the Fedora project's decision to make it default on Workstation 33.

  • Finding the real source IP: using the PROXY protocol with syslog-ng - Blog - syslog-ng Community - syslog-ng Community

    Until now collecting logs behind proxies or load balancers needed some compromises. You either trusted the host information included in the log messages or you could only see the proxy as the sender host. Starting with syslog-ng 3.30 there is a third option available: using the PROXY protocol. While not an official Internet standard, it is supported by a number of popular software, like HAProxy. Other software can be extended to use it, like F5 load balancers using iRules. This way crucial information about the original network connection is not lost, but it is forwarded to the server by the proxy.

    From this blog you can learn about the PROXY protocol, how to enable it in the syslog-ng configuration, and how to send test messages using loggen directly and through HAProxy.

In the modern era, the world has seen major progression in the technological sector. New and advanced technologies have made the lives of people easier. Not long ago, people used landlines to communicate with one another, but now, devices such as smartphones have arrived. Such advances have truly revolutionized the lives of humans in ways that go beyond the concept of communication. Such has been the impact of technology on our lives that every aspect of modern life has been merged with it. Whether it involves our finances or our social profiles, all rely heavily on technology.

However, this reliance of ours has made us much more vulnerable to data breaches. The real-life cases of Adobe and eBay clearly indicate what a serious issue cybersecurity is. Cyberattacks have also been on the rise and, to top it off, even more advanced and new kinds of attacks are being developed every day. Although Linux is much more secure than Windows and other operating systems, it is still vulnerable to viruses.

  • How can I make Nginx Faster? – Linux Hint

    Nginx is considered one of the most commonly used web servers today. The reasons behind preferring this webserver over other web servers available in the market are as follows: 1) It does not create a separate worker thread for each incoming request; rather, its single worker process is capable of catering to multiple requests at the same time. 2) It loads the static content immediately as soon as the user requests for it because it keeps that content in its cache.

    However, there are still other hacks available out there, with the help of which we can make the performance of this webserver even better. Therefore, in today’s article, we would like to share with you some of the most efficient tips with which you can make your Nginx web server all the faster.

  • How to Find Files Case-Insensitive in Linux – Linux Hint

    If you have a large bulk of files in your computer system, it is very important to keep them organized so that you can easily access the files whenever you want. If you have a busy schedule, you may simply keep dumping files onto your computer system without even knowing where a particular file is located. In this situation, it can get very difficult to work, especially when you need a specific file immediately.
    The Linux operating system provides you with multiple commands that you can run in the terminal to find a specific file. Although, most of these commands are case sensitive, meaning that you need to know the exact name of your file and whether it is in lower-case or upper-case letters or a combination of both. If you do not know which letters are capitalized in the file name, then it would not be possible to locate the file that you need with these commands.

    There is a method that can be used to make a file search case insensitive using certain flags in the command-line interface. This article shows you how to perform a case-insensitive file search in Linux Mint 20.

To find out more, look up the LSB project.
    While you can run applications under NixOS because they follow the above standard, the files are not where they would be in another system. The developers of NixOS and GNU Guix have strong opinions about this system, and they have come up with clever ways to comply with it.

  • Turn off SELinux on CentOS 8 – Linux Hint

    The term “SELinux” is an acronym for Security-Enhanced Linux, and it is defined as a mechanism that is implemented within the Linux based systems for providing an advanced level of security that is essentially based on policy rules. By following these rules, an administrator can allow or deny access to a certain object for any specified user. It means that the security of your Linux based systems relies heavily on this mechanism.

    This mechanism works on three different modes of operation, i.e., Enforcing, Permissive, and Disabled. The first two modes work when you have enabled the SELinux mechanism, whereas the “Disabled” mode obviously works if your SELinux has been disabled. Also, the “Enforcing” mode works by applying all the policy rules that are written for SELinux, whereas the “Permissive” mode allows you to add new rules to the security policy.

    However, at times, the rules defined in the SELinux security policy are so strict that they start causing trouble with your routine tasks, i.e., they might cause a hindrance in an important task that you are trying to perform. In this situation, you may prefer to turn off SELinux till the time you perform that task and then turn it on again once you are done. That is why today, we would like to share with you the method of turning off SELinux on CentOS 8.

  • Remove Directory Recursively without Prompting for Confirmation in Linux – Linux Hint

    At times, you may have more than one directory within a single directory. This is known as a subdirectory, defined as a directory within a directory. Usually, the subdirectories within a directory are closely related to that directory. This means that whenever you feel like you do not need a particular directory anymore, then you also will not need its subdirectories further. So, the question arises, “How do I get rid of all the files and directories within a directory?”
    This is where the concept of recursive deletion comes into play. Recursive deletion aims to delete all the files and directories within a subdirectory. Generally, whenever you attempt to delete any file or a directory within any operating system, the OS prompts you to provide confirmation to prevent accidental deletion of important files or directories. However, if you are 100% sure of what you are going to delete, and there is a large number of files to be deleted, then you might find it troublesome to provide confirmation for every file or directory.

    In this case, you can remove a directory recursively without being prompted by the OS for confirmation every time. This article explains how to remove a directory recursively without prompting the user for confirmation in Linux Mint 20.

    To remove a directory recursively in Linux Mint 20 without prompting the user for confirmation, the following series of steps should be performed.

  • KeePassXC on Linux – Linux Hint

    In the present world, technology runs our lives as we have become fully dependent on devices such as smartphones, computers, etc. and it has become an integral part of our everyday lives. Such has been its impact that a life without these devices just cannot be imagined. With the invention of cars, planes, Google, and computers, humans have indeed become much more efficient and less erroneous. Things like artificial intelligence, cloud computing, blockchains, virtual reality, and so many others have opened astounding avenues for humans to explore and have allowed humans to step into a realm that could only have been imagined in science fiction books.

    However, our dependency on technology has also led to our privacy being more exposed than ever. Things like data breaches and cyber-attacks have become quite the norm and are growing in scale with time. Linux users have had less to worry about these issues as it has often been said that Linux systems are more secure than its counterparts, but it is important to remember that hackers are becoming more skilled, and thus, it still is not a hundred percent completely safe from malicious attacks. Therefore, it is essential for one to employ procedures with which they can protect their Linux systems. One excellent solution is to use a password manager, which shall also be the topic of our discussion in this article, where we will be focusing on one open-source password manager by the name of KeePassXC.
