This article will look at a problem with the network namespace file in a Docker container. We'll examine why the network namespace file is invisible to the ip netns ls command. Before moving ahead, let's have a brief overview of Docker, Containers and Network Namespace Containerization Containerization is similar to virtualization, in which an application and all its dependencies and libraries are packaged into a single container; it can run in any computing environment. When the OS kernel and all necessary libraries and dependencies are included in the container, anyone working on the application can use only the container to ... Read More

Introduction cURL (Client URL) is a command-line tool. It allows data to be transferred to or from a server without requiring user interaction by utilising the supported libcurl library. cURL can also be used to troubleshoot network connections. In some cases, we may need to send requests that bypass the cache and generate a new response from the server. Caching can occur on the client side (browser cache) or the server side. When using the cURL command, remember that it is only an HTTP client and does not cache any requests on the client side. As a result, any caching ... Read More

Introduction Hexdump shows the binary file contents in hexadecimal, decimal, octal, or ASCII form. It is an inspection tool that is also useful for programming, reverse engineering, and data recovery. It represents the content of a file in hexadecimal form. The various tools we can use to generate a file's hex dump will be covered in this article. We will learn to create a hex dump of a file. To utilise as a model for this article, let's generate an ASCII text file. $ cat >> example.txt This is our sample text in the file. We will convert it ... Read More

Introduction If a numbering system is represented in base 16 then it is considered to be hexadecimal. In this article we will understand to convert Hex to ASCII in the Linux Shell. The hexadecimal system uses a combination of digits and alphabetic characters, and it looks like this −0 1 2 3 4 5 6 7 8 9 A B C D E F Large digital systems are best suited for a hexadecimal numbering system since it can store and express long binary data. Because a total of 16 symbols (both digital and alphabetic, ranging from 0 to F) ... Read More

Introduction It is likely you have heard of Version Control Systems (VCS), or source control if you write or track code for a project. A Version Control System serves primarily as a host and a tool for tracking how a project develops. With VCSs, developers are able to compare and track changes between files, track commits, make proposals, view the history of projects, and revert to previous versions. Software teams and developers need a good VCS to implement DevOps, continuous delivery and maintain productivity. Git, SVN, Mercurial, and Perforce are a few of the most popular version control systems. You ... Read More

Even though the majority of us are accustomed to using Windows as our primary operating system, it is important for us to at least be familiar with other operating systems such as Unix, Linux, and others. This does not imply that Windows is the only operating system that has been used globally; rather, it indicates that other systems also take a larger proportion in terms of utilisation. The end functionality, which is using the computers to make our tasks easier, is the same regardless of the operating system that we might choose.Read through this article to find out more about ...

Linux terminal allows us to execute a variety of commands and sometimes it so happens that we find ourselves in a scenario where we might want to use a certain command more than once. There are many occurrences where we would want to repeat the command that we just ran. In Linux, this can be done with the help of different commands, and in this tutorial, we will explore all such commands with the help of different examples. For reference and simplicity, I will run a single command, say 'ls -ltr' and then use the different methods to search what ... Read More
