Exporting File System for NFS in Linux

In Linux, we can export a directory for NFS clients by editing the /etc/exports file.
The /etc/exports file contains an entry for each directory that can be exported to NFS clients. This file is read automatically by the exportfs command during during system start-up through rc.nfs script. It execute the exportfs command and start the nfsd and mountd daemons. If we modify the entries in this file we must run the exportfs command before the changes can take affect.
Now let us export “/home/user” directory :
Edit /etc/exports file using vi editor and add following entry:
  • /home/user host1.domain1.com(ro, root_squash)
    • This command will make /home/user directory available to host1.domain1.com
  • /home/user *(ro, root_squash)
    • This command will make /home/user directory available to all users on the network.
  • Here :
    • /home/user is the directory we want to export.
    • host.domain.com is the machine which is been allowed to see this directory over the network.
    • “ro” means mounting with read-only option.
    • “root_squash” means no root write access in this directory.
After editing the /etc/exports file, execute exportfs command to take changes effect :
  • /usr/sbin/exportfs -a

Exploring Node.js Internals

I found a great article explaining Node JS internals, must read : https://www.smashingmagazine.com/2020/04/nodejs-internals/ Some other articles : Introduction to Node.js Being an official website, Node.dev explains what Node.js is, as well as its package managers, and lists web frameworks built on top of it. “ JavaScript & Node.js ”,  The Node Beginner Book This book by  Manuel Kiessling  does a fantastic job of explaining Node.js, after warning that JavaScript in the browser is not the same as the one in Node.js, even though both are written in the same language. Beginning Node.js This beginner book goes beyond an explanation of the runtime. It teaches about packages and streams and creating a web server with the Express framework. LibUV This is the official documentation of the supporting C++ code of the Node.js runtime. V8 This is the official documentation of the JavaScript engine that makes it possible to write Node.js with JavaScript.

Tum mujhko karna maaf priye – Poem By Dr. Kumar Vishwas

Lyrics : O kalp-vraksh ki son-juhi, O amal-tas ki amar kali Dharti ke aatap se jalte, Man par chaayi nirmal badli Main tumko madhu-sad-gandh yukt, sansaar nahi de paunga ! Tum mujhko karna maaf priye main pyar nahi de paunga !! Tum kalp-vraksh ka fool aur Main dharti ka adna gayak Tum jeewan ke upbhog yogya Main nahi adhuri gazal shubhey Tum saam-gaan si pawan ho Himshikharon par sehsa kaundha Bijuri si tum man bhawan ho Isliye vyarth shabdo wala, vyapar nahi de paunga ! Tum mujhko karna maaf priye main pyar nahi de paunga !! Tum jis shaiya par shayan karo, Veh sheer sindh si pawan ho Jis aangan ki ho maul-shree Veh aangan kya vrandawan ho Jin adhron ka chumban pao Veh adhar nahin ganga tat ho Jiski chaya ban saath raho Veh vyakti nahin vanshi-vat ho Par main vat jaisa saghan chaaon ,vistaar nahin de paunga ! Tum mujhko karna maaf main pyar nahi de paunga !! Main tumko chand sitaron ka Saupun uphar bhala kaise Main yayavar banjara sadhu sur-sansar bhala kaise Main jeewan
