Save authentication on server

Most of us have to log on to a server while working on a project in our day to day life.
It is annoying to open multiple terminals and enter password for each log in.
So, how about authenticating your local machine permanently to your server login and eliminate entering password for ssh, scp etc.
perform 2 easy steps on your local machine and your goal is achieved:
1. (i) change to directory ~/.ssh;
(ii) ssh-keygen -t rsa
2. ssh-copy-id -i id_rsa @

Now you can log on to the server just by typing "ssh @".(The system will not ask for authentication(i.e password) ).

note : I faced problem if I manually created the .ssh directory in my home directory. This directory is automatically created when one does an ssh or scp.

use the public key and not the private one

Thank you for this very useful tip but it seems that there was a typo mistake:

ssh-copy-id -i id_rsa.pub @ip
instead of
ssh-copy-id -i id_rsa @

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
