Login Without Password using ssh-keygen & ssh-copy-id

Below are the steps to Login into Remote server without entering password using SSH commands: Step 1: Generate the Public and Private keys using below command:
faruq@local-sys:/tmp# ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
2c:17:97:ce:ab:ef:9e:9f:33:e5:46:67:e7:9c:53:7e root@innopark-HP
The key's randomart image is:
+--[ RSA 2048]----+
|                 |
|           .     |
|        . o      |
|       . =       |
|      . S o      |
|       o   .  o =|
|          .  + *+|
|         . .o.ooE|
|        .+=.o+  o|
+-----------------+
Step 2: Copy the Local public key to remote server using ssh-copy-id

A blow to Dial Up internet as BT shuts down service

Yes, that’s right, BT have now shut down and switched off their whole dial up service. Dial up internet has been a hugely popular method of connecting to the internet, however, in recent years, due to new methods, many have ditched the method of dial up. Dial up has always been reliable and probably is still more reliable than more modern methods such as wireless, however, dial up is known for the frustratingly slow speeds.

As more and more start to ditch the trusty dial up internet connection, it took another huge blow as major multinational telecommunications company completely cut off all of its dial up services as they stated it was only a “tiny number” still actually using dial up to get onto the web. Additionally, a spokesperson also explained that most of the 6.8 million broadband customers have switched to much faster connections.

Many people have stuck with dial up internet, despite its slow speeds because they’ve used it for many years and has been reliable, however, many people still use this method of connection only because they live in areas where broadband will not be available, this is where the shutdown of BT dial up might be a problem for some internet users. After the BT shutdown, it meant that an estimated 1,000 people will now not be able to connect to the internet because of the area they live in. This is mainly due to phone lines not being able to support the newer technology.

Despite the feared problems in terms of accessing the internet, BT believes there isn’t any problems for anyone trying to gain access to the internet. A spokesman from the business stated "They will be too far from the telephone exchange to get any meaningful broadband. The distance means that the broadband signal degrades," he said.

Those who had to stick with dial-up would still be able to get such services from BT via its PlusNet subsidiary.

"No-one is being left without the option of an alternative service." After figures were released, an estimated 800,000 people still stayed loyal to the trusty dial up connection in 2010 however, it is claimed that that number has fallen significantly.

Due to the many changes in the way people access the internet and the many modern methods to actually browse the web, it seems that dial up users are fading in numbers and more and more companies may be forced to shut down their dial up services due to the extremely small number of those using dial up.

Dial Up Could Provide Answers For Xbox One

Dial up could be the answer Microsoft have been looking for when it comes to the concerns over the upcoming release of the Xbox One. Although it might seem at times to be an outdated form of internet connection the dial up connection has not yet died out and is still used much more than many people think it is, and it may prove to be the ideal option for a lot of gamers.

Interestingly Dial Up users are still common enough to produce around $500million every year for AOL alone, and they certainly aren’t the only company still succeeding in selling dial up subscriptions, which begs to question whether or not the service really is dead or not. For people who don’t require an internet connection very often or for very long this is an ideal option, as charges are low and you are only charged for what you use, which makes it pretty easy to connect and you don’t have to worry about a broadband bill at the end of the month, which will be the same regardless of whether you used it or not.

Of course if you’re wondering how this could aid you in your hopes of getting hold of the Xbox One; which is already famous for needing an internet connection every twenty four hours or else it will prevent you from playing your games. A revelation that caused concern to many who just don’t have internet connections, or don’t feel secure leaving their console connected to the internet all of the time – a problem that doesn’t occur with dial up.

First of all dial up is ideal for this because there are no real requirements for dial up, all you need is a phone line to connect to. The dial up bill is then charged to your phone line and comes with your usual phone bill, and the connection that would be required to connect to the Xbox would only last for a few minutes and most likely cost very little. Another reason why this is ideal is because dial up internet connections are in fact more secure than broadband, due to the fact a new IP address is generated every time you connect.

There are rumours circulating the internet that suggest Microsoft have already stumbled upon this solution and intend to build a dial up router into the device that will make connecting to dial up internet to perform the required 24 hour check. The rumour also suggests that Microsoft will include a dial up number in a leaflet that won’t require a subscription and will allow you to connect to the internet through them, however the main question is whether or not Microsoft will be able to accommodate this need. If the modem and dial up connection number are provided as the rumour suggests then would Microsoft be fully equipped to handle the number of connections coming at peak times and keep the speed up? The problem with Dial Up is that you pay for how long it takes, not the speed you get, so slower speeds at peak times will mean higher charges.

Whether or not the rumours are true you will still be able to connect your Xbox One to the internet using Dial Up much in the same way that many have done with the Xbox 360 for their Xbox live; though depending on your dial up provider you may experience lag when trying to play multiplayer games with Xbox live. A good idea is to look into a good dial up provider, there are those that require no subscription, offer low charges and even provide reasonably high connection speeds, many of which are perfectly capable of handling a large number of connection requests without dropping speeds or incurring engaged tones while attempting to connect.

UK Rail Internet Set to Improve

Britain’s busiest rail networks are due to have the fastest internet speeds available by 2019. It is thought that a staggering 70% of train passengers will have access to the faster internet speeds allowing them to have better use of their mobile phones. The speeds are expected to be so vast that passengers will even be able to stream videos onto their mobiles.

With the railway being one of the most popular forms of travel it is important to maintain its services and better those that people want and need. This will ensure that people continue to use the railway and in return receive an exceptional service. At the moment mobile phone communications on the railway are not that good causing people to lose connection and have no signal at all. It is for these reasons why the connections must be improved to keep passengers happy.

Network Rail is currently undergoing a £1.9bn digital communication improvement programme. This will improve both the fixed line and mobile infrastructure of the rail network. Once the fibre optic network is installed it is hoped that it will be able to handle up to 192,000 gigabits per second of data. It is estimated that the installation will be completed by June 2014.

The reason for people having such limited data access now is down to the train operating companies only providing 2.5 megabits of data per vehicle. This then has to be shared out amongst the passengers on the train leaving little room for video streaming. This is why the companies block services such as iPlayer, Netflix and Love Film. With the new upgrade however each vehicle should be able to receive at least 50 megabits of data allowing the current policy to change so that people have access to the services they want to reach.

The upgrades however will of course cost the likes of Network Rail, mobile phone operators and train operating companies. How much is yet to be decided as is the cost of how much the passengers on board the train would be charged for using the service. One thing is for sure though that passengers will be happier and benefit from the changes that are to be made.

Plans to Make the Internet 100x More Affordable

The internet is a massive part of many of our lives, yet you might be surprised to know that a staggering two thirds of the world still have no access to it. With this in mind Mark Zuckerberg, the creator of Facebook has teamed up with a number of tech companies to try and change this. Ideally Zuckerberg would like every person in the world to have access to the internet to help improve and make their lives easier.

In order for this to work however the internet will need to be made at least 100x more affordable. This will allow any person with a phone to aces the internet wherever they are with ease. To complete the task a lot of big changes would need to be firstly made. Some of these include upgrading cell phone towers to allow signal to travel further than they already do, clearing up airwaves so that a spectrum can be used more efficiently and to reduce the costs of smartphones so that more people can afford them.

As well as this he mentioned that the level of data should be reduced in order to supply the basic services. A number of ways to do this have been suggested including apps storing data rather than requesting it and by compressing data so that only 40% of it has to be transferred. Zuckerberg mentions that he was able to create the likes of Facebook by having access to only a few basic tools and he wants to make this possible for others.

If the plan works the internet will provide many people with a platform where they can share and gain knowledge from others. It is believed that much of today is based in a knowledge economy and in order for this to keep growing more people need to have access to the internet.

It is thought that the cheapest form of internet usage today is dial up internet as it gives user the opportunity to pay only for what they use. This is a great service for many however if the plan to make the internet 100x more affordable than what it already is, there may be no need for trusty dial up service to exist. This of course is only a thought and whether or not this will actually take place is something we will just have to wait and see.
