First you will have to generate key on local machine.
For that type in the following command in a terminal. Here we are using RSA encryption.
ssh-keygen -t rsa
It will ask you for a password but you can leave it blank.
Note you could also pick -t dsa if you prefer DSA encryption.
Ensure that the remote server has a .ssh directory
Make sure the server your connecting to has a .ssh directory in your home directory. If it doesn’t exist you can run the ssh-keygen command above, and it will create one with the correct permissions.
Copy your local public key to the remote server
If your remote server doesn’t have a file called ~/.ssh/authorized_keys2 then we can create it. If that file already exists, you need to append to it instead of overwriting it, which the command below would do:
scp ~/.ssh/id_rsa.pub remote.server.com:.ssh/authorized_keys2
Now ssh to the remote server
Now you can ssh to the remote server without entering your password.
Security
Now keep in mind that if someone need to login to the remote server, all s/he need is the file on your local machine ~/.ssh/id_rsa, so make sure it is secure.

The newest version of the popular Avast Antivirus is finally available for download. It’s lighter, faster, and more feature-filled than ever, bringing a new behavior shield, heuristics engine, and code emulator to keep you protected at all times.
Apart from its far easier-to-navigate interface, Avast has a few new features that make it hard to turn down. Its new code emulator can emulate a suspicious executable’s code, isolated, for use in its new heuristics engine, designed to detect malware that would otherwise be undetectable with normal definitions—in other words, spotting malware by learning what the code does. If you use the pro version, you also get their new sandboxing feature for even further protection.
Apart from the new features, Avast has also lowered scanning times as well as the resources necessary to scan and update—a common issue with antivirus programs that are always running in the background. If you’re already an Avast lover (and many of you are), you can either wait for the program to update itself in the near future or go download 5.0 straight from Avast. If you’ve tried Avast and turned it down before, it may be worth another look—you may find that its former cons (such as the difficult-to-use GUI and resource use) are now more up to your standards.
Avast Antivirus is a free download, Windows only.

Today Guardian.co.uk reported that the famous Chinese Search engine Baidu Got hacked. Chinese internet users were unable to use the Baidu search engine after it was targeted by hackers called the ‘Iranian Cyber Army’.
Guardian Said,
The search engine is widely regarded as having good relations with the Beijing government and has never been associated with sensitive content. That led other internet users to speculate that foreign hackers were attempting to discredit Iran.
China’s state-run People’s Daily website reported that Baidu’s website began redirecting to a site attributed to the Iranian Cyber Army at around 8am (midnight GMT). The People’s Daily site published a screen grab showing a message reading “This site has been hacked by the Iranian Cyber Army”, alongside a picture of the Iranian flag.
Other users said they could not open the Baidu site, but it was back up and running by around 11.30am. In a statement, the company said: “Services on Baidu’s main website www.baidu.com were interrupted today due to external manipulation of its DNS (Domain Name Server) in the US. Baidu has been resolving this issue and the majority of services have been restored.”
