DCP – Transfer Files Between Linux Hosts Using Peer-to-Peer Network
As a Linux user, you may often find yourself needing to transfer files between different hosts on your network. While there are several ways to do this, the Distributed Copy (DCP) protocol is a peer-to-peer method that offers a convenient and efficient solution for large-scale file transfers. In this article, we will explore DCP in detail, including how to install and use it to transfer files between Linux hosts. We will also discuss security considerations when using DCP, and how to use SSH to ensure secure file transfers. What is DCP? DCP is a protocol that enables ...
Read MoreDifference Between .a and .so files
A programmer may want to write three different programs. However, he realizes that some of the functionality needed for each program could be shared among them. Therefore, he decides to create a library containing these shared features. A library is basically a collection of code and data that other people can use. On Linux, archives (with the .a file extension) contain compiled object code, whereas shared objects (.so files) contain code that can be dynamically loaded at runtime. Here, we'll examine how software runs under Linux and the purposes of the library and archive files. We'll also see ...

Read MoreConfigure _No Password SSH Keys Authentication_ with PuTTY on Linux Servers
SSH (Secure Shell) is a popular protocol for securely connecting to remote servers over a network. When you use SSH to connect to a server, you typically need to provide a username and password to authenticate your identity. However, this process can be tedious if you need to connect to multiple servers frequently. Fortunately, there is a solution: No Password SSH Keys Authentication. In this article, we'll walk you through the process of setting up No Password SSH Keys Authentication on a Linux server using PuTTY, a popular SSH client for Windows. With this setup, you can connect to ...
Read MoreConfigure Collectd as a Central Monitoring Server for Clients
Collectd is a lightweight system statistics collection daemon that gathers performance metrics such as CPU usage, memory utilization, disk I/O, and network traffic. It operates as a central monitoring solution, allowing administrators to collect data from multiple client systems and analyze it from a single server location. This article demonstrates how to configure Collectd as a central monitoring server to collect metrics from distributed client machines and visualize the data using modern dashboards. Prerequisites Before configuring Collectd, ensure you have the following − A server running Linux (Ubuntu or Debian preferred) One or more client ...

Read MoreDelete expoted environment Variable in Linux shell
This article explains how to delete an exported environment variable from the Linux shell. Environment variables are key-value pairs that store system and user configuration information accessible to all processes running in the system. Understanding Environment Variables An environment variable is a named storage location that contains data used by the operating system and applications. When a variable is exported, it becomes available to child processes spawned from the current shell. These variables are stored in the process's memory space and can be accessed programmatically using functions like getenv() in C. Listing Exported Variables Before deleting ...
Read MoreWhat is the sed in-place flag that works both on Mac and Linux?
The sed command in Linux stands for stream editor and is mainly used to perform functions on files, such as searching, replacing, or inserting text. It is a very useful command-line utility available on Linux systems. However, there's an important difference between operating systems: the BSD sed shipped with macOS requires a mandatory argument with the -i flag, while GNU sed on Linux makes this argument optional. The Cross-Platform Solution The most reliable way to make sed work identically on both Mac and Linux is to use the -i flag with a backup extension. This approach works ...
