SSL ( SECURE SOCKET LAYER):

SSL (Secure Sockets Layer) is the standard security technology for establishing an encrypted link between a web server and a browser. This link ensures that all data passed between the web server and browsers remain private and integral. SSL is an industry standard and is used by millions of websites in the protection of their online transactions with their customers

To be able to create an SSL connection a web server requires an SSL Certificate. When you choose to activate SSL on your web server you will be prompted to complete a number of questions about the identity of your website and your company. Your web server then creates two cryptographic keys - a Private Key and a Public Key.

The Public Key does not need to be secret and is placed into a Certificate Signing Request (CSR) - a data file also containing your details. You should then submit the CSR. During the SSL Certificate application process, the Certification Authority will validate your details and issue an SSL Certificate containing your details and allowing you to use SSL. Your web server will match your issued SSL Certificate to your Private Key. Your web server will then be able to establish an encrypted link between the website and your customer's web browser.

The complexities of the SSL protocol remain invisible to your customers. Instead their browsers provide them with a key indicator to let them know they are currently protected by an SSL encrypted session - the lock icon in the lower right-hand corner, clicking on the lock icon displays your SSL Certificate and the details about it. All SSL Certificates are issued to either companies or legally accountable individuals.

Package: ssh

Portno: 22 default

service : sshd

#ssh 192.168.1.10

here it will login to other systems through ssh

#ssh -P 2222 192.168.1.14

to change the port no so that no one can login

we can generate keys through dsa or rsa

the below is used for private keys so that no passwd required for every time login

#scp -p 2222 /root/.ssh/id_dsa.pub root@192.168.1.14:/rtoot/.ssh/authorized_keys

#ssh -p 2222 192.168.1.14
