Setting up LAN with BSNL router AN 1020-21

An abstract overview for building a LAN is presented here, you can use the essence of article to build LAN with any other router you can lay your hands on. That said don't confuse modem with router, most routers are modem but a modem simply can't be router*

Post is written in the hope that reader is equipped with basic knowledge about connecting line to splitter to router to device you want to use. It is assumed the your modem is configured for both wireless and ethernet access.

My work requires that I interact daily with servers using putty or such terminal emulator, gradually I loved doing work the *nix way. This made me install Cygwin in almost every machine I use, thanks to MobaXTerm I need not do that anymore :) Off story on to TODO.

1. Connect the machines you want to use to Router
That's all! Your router takes care of establishing (W)LAN

Surprisingly simple to establish LAN, but the hard part is knowing how to use the systems connected in the network. Here is the network topology in my home

If you have the habit of naming your computers you are almost saved. I have the habit, my phone is called owl, my laptop is beast, old machine that runs lubuntu is called delta (I have no idea why I gave such names). If you have given names to your machine try pinging them with names.

C:\Users\nemo>ping delta

Pinging delta.local.lan [192.168.1.3] with 32 bytes of data:
Reply from 192.168.1.3: bytes=32 time=2ms TTL=64
Reply from 192.168.1.3: bytes=32 time=2ms TTL=64
Reply from 192.168.1.3: bytes=32 time=1ms TTL=64
Reply from 192.168.1.3: bytes=32 time=2ms TTL=64

Ping statistics for 192.168.1.3:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 1ms, Maximum = 2ms, Average = 1ms

C:\Users\nemo>ping -a localhost

Pinging beast [::1] with 32 bytes of data:
Reply from ::1: time<1ms
Reply from ::1: time<1ms

Reply from ::1: time<1ms

Ping statistics for ::1:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 0ms, Maximum = 0ms, Average = 0ms

Yes,Yes you are awesome, the second ping was target at localhost with request to resolved domain name at it turned out to be beast, cool ways to prove you know commands duh...

 What to do when you haven't named, or have named but no response?

 1. Go to Router admin page
Mostly:- http://192.168.1.1/
{
For BSNL unless you have not tinkered,
Username : admin
Password : admin
}
2. Locate the DNS Host listing page
{
http://192.168.1.1/webconfig/dnsrelay/dnsrelay.html
}
3. Verify if your device is connected, oh yes there will be a domain name by default if you haven't overridden you can see it here.

You might ask... why were you talking about putty. well as I told already I have lubuntu installed in my old machine which I intend to use for stupidity ;) I have installed open-ssh-server on it and now I'll be able to connect to it via any terminal emulator

Normally domain name is enough to connect, if your tool finds it difficult use domain_name.local.lan . Here I'm going to connect to delta from beast with MobaXTerm Personal.

Modem : Connects you to Internet. Think like connects 1 device to internet
Router : Connects all the devices connected to it to Internet. Think about Wifi modem as we casually call it. It is router.

You can ask what is the difference. Think like this, you and your dad are connect to your home wifi. Your dad is paying bills late night (bcoz dad's are responsible figure). You are having nasty chat with your friend(s) . If router doesn't do the job correctly the snapchat picture aimed at you might be received in your dad's device... imagine he'd be paying LIC premium and seeing naked mole rat instead of Receipt "Payment is successful" :D

Technically router takes care of delivering response to correct device which made the request by establishing LAN internally :)

Puththu kovilum Putho tilesum, as they are built

Its the grand Aadi season here in Tamil Nadu wherever you go you'd be followed by awful noise from no mercy speakers masqueraded as a devotional song. Yes, this is the first post dedicated to it. Hindu is not a religion but it's idealism, a way to unite people, that's perfectly constructed by assuming separate task to every God, no single God worship. Hindus moved from nature worship to idol worship, but that doesn't mean that we don't have nature worship we have created an idol for them and continued to worship them in a different form. Snake is a beautiful reptile, I have made friend with few too... Our ancestor found the natural law, 'every living creature on earth is important for the ecosystem to be balanced'. Maybe to make sure snakes are not killed fearing their venom they made them as God too! Not just idol snakes, they are worshipped as they are at their  conquered (from rats and termite)   nest or  puthu . Puthu as it used to be in open

Up and Close with Sudalai Madan: The Encounter

Night of 13th April all the preparations for the rituals were done in the temple, Sudalaimadan swamy was decorated with flowers, fruits and coconuts; the dedications reached above his chest. My cousin Sudalai Muthu, senior priest of the shrine reached home by late-night got blessings of his father Late Shanmugam Sundaram also previous head priest and blessed the family members in room dedicated for God, then started towards the temple. People have already gathered in huge numbers and were waiting for the Sudalaimada Swamy's arrival at Temple. Different rituals were offered by people to the Lord in order to get the blessings. As it is believed Sudaimada Swamy, the son of Lord Siva used to consume meat in Kailash for this reason he is sent to earth, where he can satisfy his earthy hunger thereby not polluting Kailash. Sree Aaladi Padmanabha Sudalaimada Swamy Temple, Kumarapuram Offering meat to Sudalaimadan is the most important and watchful event of the festival. Many devotees off

It doesn't have to be crazy at work

It doesn't have to be crazy at work, is the book with that title. The title is almost clickbait, but the gist is printed straight up on the cover of the book; they didn't even wait for the blurb. Jason Fried, the CEO and David Heinemeier Hansson, the CTO of 37Signals (formerly Basecamp) co-authored this book. This book was gifted to me by whom I'd consider to be a mentor because he caught me working "crazy at work", it is rare to see such people who are more inclined to see you as a person instead of a number, he seemed to have taken guidelines from this book to heart, and I'd say it is a good change in this cut-throat corporate. This is yet another book discussion, it is almost as if I am picking books to only learn and not review them; I'm not a reviewer, and I do not have any affiliate account setup that will earn me commission; I'm just going to discuss the ideas that I grasp from the books I read, on to the book The book is about how crazy the wor

The Difficulty of Being Good

This is not a book review, rather a discussion or an elaboration of what I understood from this book. The author, Gurcharan Das starts by claiming that his path to this book was rather unintentional since he was only trying to settle into his " Vanaprastha " life. He discusses the  goals of life and how every stage of life connects with many goals at the same time. Head on from chapter 1, we dive into the core of the book, "Dharma" the main goal of a good life well-lived apart from 'Moksha'. The best thing about the book is that the chapters are arranged such that Mahabharata's chronological narration is undisturbed, chapters are character-centric and thus dharma is approached from various points of view and Mr. Das never stops throwing questions at us and subtly answering them.  This book could not have come to me at a better time, I considered it non-intrusive advice from an elderly vanaprastha. The sub-text gives away the plot, almost, "The subt

Product of Govt. aided School, but does it matter?

I started my work life in an MNC, Tier 1 IT service provider. I worked with clients directly since I was able to understand and speak their 'accent'. My second employer is an Italian bank where both my Indian and Italian colleagues praised my spoken, never mind that I almost always fail to communicate. It is funny that I picked up the accent from American sitcoms and cartoons and didn't undergo any sort of training.  I can hear you say "stop this nonsense bragging blog", I will after I manage to sell you the idea 'schooling is important, but schools or education boards are not'.  But why now? why not 2011? when I got the job and the girl? Probably that is the highest point in my life why was not be boastful then! why now? - Again I'm not boasting I'm only trying to convince myself and you, of course. This idea had its inception long back, 2007 was my first year of college I was considered to have a fairly high standard of communication skill in c
