Reality versus opinion

After my retina test, I became almost blind for a day. Not able to see properly, mainly in sun light. So while waiting for an auto/taxi to home at hospital, one blind man requested my help to cross the road. Although I was little better on vision than him at that time, still I didn’t take dare to put somebody’s life in risk. So I requested an (unknown) young girl to help him, who was standing beside me. She is really a nice girl. She accepted my request and helped him to cross the road after throwing a word ‘stupid’ to me. Probably she was not aware of my situation at that time or I would have explained my condition while requesting her help for somebody else.

Everyone is having their own opinions, which turns into beliefs after some times. The way you feel about any topic or situation, is shaped by the way you perceive the reality around you. You should remember one thing; there are different types of people. The way you perceive might be completely different than what others think on the same. So instead of reacting on anybody’s opinion, it’s better to express your opinion in front of all. I really like this uniqueness of diversity of creation. And I am a guy, believe on discussing the matter and like to know the different aspects of all the amazing ways in which creation can manifest itself.

Generally young people use to get ignited easily and give comments immediately, looking on few aspects of the matter. It might not impact them at that period of time, but may put somebody in trouble and sometime for themselves too. So when you present a certain belief in front of others, be open to the fact that they may not agree with you or may choose a different path in life that is very different to yours. Instead of feeling offended, rather respect them for their differences and you deserve the same respect in return. Remember, the path you have chosen is not the only path and is not necessarily the ‘right’ path. But you will be happy that what you have selected, you feel that is correct one at that period. Don’t worry, if you are really ‘right’, people will understand you and may follow also.

Looking myself through the mirror!

In this digital days, being a software engineer, my daily life starts with internet and ends with it too. And while going to bed, I get chance to think on ‘what did I do today?‘ Answer comes- firstly ‘working for office’ (on returns I get some bucks to live), secondly ‘googling’ to familiar with current updates and lastly ‘chatting’ for keeping relation with others. But when I ask myself, ‘what did I learn in past 24 hours?‘. There was no answer..!!!

This learn word comes with three questions! ‘What do you do?‘, ‘How do you do it?‘ and ‘what is your goal?

Just you as a man who, wanting to see your face, look first in a little pool of muddy water, and see just an outline; then you come to clear water, and see a better image; then to a piece of shining metal, and see a still better image; and at last to a looking-glass, and see yourself reflected as you are. That’s we call ‘improvement‘.

When you were a child and thought in one way, now you are a man and think another way, again you will be an old man and think differently. Same case happens for everybody*!! If so, where is your individuality?? If you can compare between your thoughts in childhood and during middle age, then why are you not comparing yourself everyday with previous day? Your improvement will come along with your patience, effort you spend on a subject and how you work on the subject! It shouldn’t be the same way what you did previous days. There is a need of some changes on the working procedures to get a different result.

Wish You Happy New Year…

New Year brings something new in life. A basketful of very many exciting hopes and an unimaginable spirit to overcome all odds. Frankly speaking, I have no resolution in the reckoning for a blissful new year but my whole heart and mind goes on to say……………

Dear Mom, Dad & God,
Graciously one more year is going to be added to the pages of my life. Thank you for supporting me for the past one year like any other years from my birth. I thank you for a warm bosom and a roof for my head on cool dark nights. I enjoyed all the meals that you provided over the year. Again I thank you for the gift of companionship and I am so glad to get chances to meet so many friends @wordpress/@facebook/@office etc 🙂

Hi friends,
Thank you all for inspiring me in every steps of my life. Wishing you a new year filled with new hopes, new joy and new beginnings… 🙂

802.1x Love Story in Layer-2 Switches

Sorry friends. I took long gap to publish a blog on educational stuffs. Anyway today I am going to explain one incident, happened during my last training session. So cool down and let’s start the topic!

It was the session on 802.1x Port Authentication. Like my other training sessions, I completed it 15 minutes before the schedule, and switched for funny discussion on same topic. One girl asked me, how I could relate this authentication protocol with my life!

Hmmm… Now your turn!! Could you remember my earlier DHCP blog? I just told similar kind of story on reply of her crazy question. Let’s follow that story!!

One declaration: I have a plan to create another blog site for only technical stuffs without any funny ideas (I will try to avoid. Okay??). Do you wanna like this plan??

However, similar to my earlier blogs on education, this blog is not meant for people who are bit boring or scary to relate funny matters with what they study in their class books or on which they work everyday.

This blog is written, guessing that you have some idea on 802.1x Port Authentication Protocol. And here is a freaky look on same protocol to remember it easily.

802.1x Port Authentication Protocol

Ref: IEEE 802.1X Wiki
802.1x authentication process

Abbreviation:

Xsupplicant Client: Myself
Layer-2 Switch: My lover
RADIUS Server: Her family

I struggled a lot to make my lover agree. Initially she was not talking with me. I don’t know, why girls ignore guys at the beginning! OK leave this topic here. Because my main focus is to explain, how she became agree to marry me and what steps I followed to impress her as well as her parents to make them agree on my proposal.

In this love story, I bravely initiated the proposal as “EAPOL-Start” packet for the girl (with whom I was in love) with the information like- who am I, where I am staying, what is the purpose for initiating EAPOL-Start packet.

She took some time. However she agreed with my proposal and replied as message called “EAP-Request” adding own identity information including some hints on the process to be followed while talking with her parents. Because it was huge chance to get EAPOL-Reject/NAK message for my single mistake.

I had three options:

  • EAP
  • EAP-TLS
  • EAP-MS-CHAP v2 & EAP-TTLS
MD5 Authentication Method

EAP process is very easy. It just believes on PASSWORD with MD5 authentication method. So I thought, it will not be a good choice to choose. Because it’s rarely seen that girl’s parents agree on marriage proposal, knowing just name and cast information of a guy.

TLS Authentication Method

So my next choice was EAP-TLS. But before I explained on this method, one of brilliant guys explained it!

EAP-TLS uses the Transport Layer Security (TLS) public key certificate authentication mechanism within EAP to provide mutual authentication of client to server and server to client. With EAP-TLS, both the client and the server must be assigned a digital certificate signed by a Certificate Authority (CA) that they both trust.

Nicely explained and I appreciated him for information shared. As I didn’t have much information on her parents like- how are they? what type of guy they are looking for their daughter etc etc. So dropped my second choice. Also I expected faster & more secure communication media during discussion with her parents. So I had third choice as EAP-MS-CHAP v2 (which is available only with PEAP). Suddenly another guy started explaining PEAP method.

PEAP Authentication Method

PEAP is an authentication method that uses TLS to enhance the security of other EAP authentication protocols. PEAP provides the following benefits: an encryption channel to protect EAP methods running within PEAP, dynamic keying material generated from TLS, fast reconnect.

“Ordinarily EAP-PEAP uses TLS only to authenticate the server to the client but not the client to the server.  This way, only the server is required to have a public key certificate; the client need not have one”, I added.

TTLS Authentication Method

Listening this explanation, one of girls wanted to know, why I didn’t choose EAP-TTLS by adding its benefits in front of all.

The Tunneled TLS EAP method (EAP-TTLS) is very similar to EAP-PEAP in the way that it works and the features that it provides. However the difference is that instead of encapsulating EAP messages within TLS, the TLS payload of EAP-TTLS messages consists of a sequence of attributes.  By including a RADIUS EAP-Message attribute in the payload, EAP-TTLS can be made to provide the same functionality as EAP-PEAP.  If, however, a RADIUS Password or CHAP-Password attribute is encapsulated, EAP-TTLS can protect the legacy authentication mechanisms of RADIUS.

I calmly explained that I had no interest to use any PROXY while communicating with her parents. So EAP-MS-CHAP v2 was the better choice at that time.

Listening this hidden story, all people in the training room started wishing for my marriage. But I stopped them at the middle and told that it was just a story, not a real fact!! I could feel, why girls threw nice smiles at me after my last statement!! Anyway training was ended with a joyous environment. But you have full rights here to ask any query on 802.1x protocol.

A journey to Hogenakkal, India

“I can’t believe there is such an amazing place so close to Bangalore,” I said when my friend gave a proposal for Hogenakkal waterfall. It was getting predictable – show pictures of Hogenakkal to anyone who has little idea on “Niagara Falls”, tell them it is just 180 km far from Bangalore and wait for them to gasp and react with those words – ‘I can’t believe…!’

A year ago I uttered similar words myself while seeing friend’s pictures at Niagara Falls. As a hills & waterfall lover, I immediately agreed on my friend’s proposal. And we three friends started our journey on the early morning just after one day. We reached there around 11:00AM, felt hot as we were habituated on Bangalore cold climate.

Waterfall was bit far from car stand. So our first goal was just to see water in that hot morning. After 15-20 minutes of exploration, we reached at bottom of waterfall, looks partially nasty place due to oil massage, and many people were bathing & cleaning dresses etc. So we postponed our willingness of going into water after noting, people are main source here to waste so clean and healthy water. You should know, the river flows through a forest before reaching Hogenakkal, which has herbs that are traditionally believed to enhance health.


Before starting our trekking to main water fall, we preferred to finish our lunch and jumped into a hotel for freshly cut fish at the bottom of hill. Although heavy fish meal after long travel was forcing us to take rest for a while, but we couldn’t control our eagerness to see the most awaiting place in front of our eyes. Hence we started following path towards main fall.
But hot weather didn’t allow us to climb for long time. We decided to play some fun under clean & chill water at the middle of the way towards initial point of waterfall.



We stopped us for sometime at the end of foot path and felt glad to see our most amazing waterfall. But it was just middle of the journey whereas our target was to go till starting point of Hogenakkal waterfall. But rain stopped us for a while and soon after the rain stopped, we started our next journey by boat. It was little scary to travel by bamboo where water level is more than 100ft and water force was not so smooth after rain.


But still I want to give “Thanks!” to boat driver as he didn’t tell it during starting of our boat journey, otherwise I would have missed another half part of Hogenakkal as my other friends initially showed some fear to travel by bamboo boat after rain. Boat was drove through big big hills having both side lots of small small streams.



After half an hour of boat travel, we had to start walking through a thick forest, where a nature lover can’t stop himself/herself to capture the beauty of nature within his/her camera. During this walk, we enjoyed the main water fall from very close. I couldn’t believe it at that time, seemed like I was seeing dream.


While this enjoyment, we couldn’t notice, when the day was about to end. Hence we started walk fast through the forest as we planned to complete the remaining part before sun sat. And we reached at the other end of forest, where our boat driver was waiting.

He dropped us at entrance of Hogenakkal waterfall. It was cloudy afternoon, made our tour amazing. Otherwise we wouldn’t have enjoyed trekking/walking at tourist place available within hottest state of India.

ogenakkal Falls or Hogenakal Falls is a waterfall in South India on the river Kaveri. It’s considered as one of the most beautiful places in the state. The broad stream of the River Kaveri gets forked at this point, forming an island from where one stream continues on while the other plunges into a deep chasm to create one of the loveliest waterfall giving these rocks the name Hogenakkal which means “smoking rock”. It offers long treks in the surrounding Melagiri Hills and one can explore the lush, rugged, landscape. It is located in the Dharmapuri district of the southern Indian state of Tamil Nadu, about 180 km (110 mi) from Bangalore. It is sometimes referred to as the “Niagara of India”, offer an exciting holiday destination for Indians and foreigners alike. Hogenakkal is located about 750 feet above sea level amidst the Melagiri Hills.

“Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work. And the only way to do great work is to love what you do.” he told at Stanford grads on June 12, 2005.

“If you haven’t found it yet, keep looking. Don’t settle. As with all matters of the heart, you’ll know when you find it. And, like any great relationship, it just gets better and better as the years roll on. So keep looking until you find it. Don’t settle.”
