Hello Everyone!

Today we will learn how to establish the SSH Tunnel using the Public and the Private Keys.

Take an example, you have a Computer and you want to communicate with a Server.

You have the public keys available in your computer.

Since these are 'Public' they can be shared across.

You will share these Public keys to the server.

The Server will create a 'Secret Message'.

Using you Public key it will encrypt this Secret Message and create a Top Secret Key.

Now this key will be sent back to you.

Since the encryption has been done using your Public key, you will use your Private key

to unlock this secret key.

When you unlock, you get the secret message.

You then share the secret message back to the server.

When server receives this message, it verifies that it is the same message and gives a confirmation.

The moment it confirms, a SSH Tunnel is established and you can communicate over the tunnel.

As simple as that.

Christmas in the USA: A sampling of public opinion | IN 60 SECONDS - Duration: 1:21.

Merry Christmas!

90% of Americans in a November

Monmouth University poll say they plan to celebrate Christmas, down slightly

from 96 percent who gave that response in a similar Gallup poll a quarter

century ago. In a 2017 poll, the Pew Research Center suggested that the

nature of Christmas may be changing, driven in part by generational change. In

the poll, majorities of all age groups felt that religious aspects of Christmas

were emphasized less than in the past, but older people were bothered more by

this than younger ones. There is other evidence of changing attitudes. 42% of

millennials, compared to 58% of boomers, say

they plan to attend religious services on Christmas Eve or Christmas day. 6

in 10 millennials, compared to 46 percent of boomers, say it doesn't matter

to them whether merchants say "Merry Christmas" or "Happy Holidays".

Older people prefer "Merry Christmas". Politics aside, more Americans find the

holiday season more enjoyable than stressful compared to the rest of the

year, and around 8 in 10 planned to gather with family and friends on Christmas.

Delhis worst air pollution this year raises fear of public health crisis World news - Duration: 3:19.

Delhis worst air pollution this year raises fear of public health crisis World news

Authorities in the Indian capital rate conditions as 'severe to emergency'

Authorities in the Indian capital rate conditions as 'severe to emergency'

Pollution levels in Delhi have hit their worst this year in the past two days, prompting authorities to rate conditions as "severe to emergency", which indicates potential for a public health crisis.

Senior government officials said the main reasons for the increase in smog were unusually cold air, fog and a lack of wind.

Such conditions trap vehicle fumes and pollution from coal-fired power plants, industry and domestic fires over the city.

Data from the government's Central Pollution Control Board (CPCB) showed the air quality index, which measures the concentration of poisonous particulate matter, was an average of 449 on Monday, only slightly better than 450 on Sunday.

The index measures the concentration of PM 2.5, particles that are less than 2.5 microns in diameter and which can be carried deep into the lungs. The previous highest recording this year was 447 on 15 June, when there was a dust storm. Anything above 100 is considered unhealthy.

India's weather department said the index reached 654 in some parts of the city, and that visibility was down to as little as 200 metres.

Environmentalists said authorities's inaction was inexcusable and that a concerted effort was needed to reduce pollution from vehicles and industry.

"If this is not an emergency, then what is?" asked Delhi-based environmentalist Vimlendu Jha.

The "severe to emergency" rating mean the air is not only hazardous for citizens with existing respiratory problems but can also seriously affect healthy people.

Conditions are likely to remain severe on Christmas Day, when CPCB data suggests the PM 2.5 level may average above 400 and hit a high of 534 in some places.

CPCB announced measures such as shutting factories and construction sites in heavily polluted areas until Wednesday along with an advisory to avoid using diesel-powered vehicles.

Steps this year have failed to make much difference and instead there has been finger-pointing between Narendra Modi's administration, the city government and state authorities around the capital.

The public's apparent lack of concern about air quality gives federal and local politicians the cover they need for failing to address the problem, say pollution activists and social scientists.

India's toxic air claimed 1.24 million lives in 2017, or 12.5 percent of total deaths, according to a study published in Lancet Planetary Health this month.
