What I learned Today " Password less login for your servers "

Hi all ,

Even though some of the servers are  compromised using passwords , So to avoid those kind of issues we have to setup Password less login to ensure high safety and security to our servers.

Steps : Create SSH keys to your user id in your server , use bellow commands to create SSH keys ,

cd ~/.ssh
ssh-keygen -t dsa -b 1024

Create an PEM key from an gerenated PRIVATEKEY

openssl dsa -in id_dsa -outform pem > test.pem 

Copy generated Public key to Authorized_keys file,

cat id_dsa.pub >> authorized_keys

That's it we are done with the key generation. We have to do is to copy that pem key to 

local machine and log in to  that server with this pem key.

ssh -i "test.pem" username@servername 

That's it we are good to gooooo.....!!!!!
