Connecting to another PC without having to enter password everytime

Hi guys, 

I'm sure that like several times you have to connect to server and its really very boring to everytime having to enter the password. So the basic concept is to use a to generate a pair of public and private keys and then push your public key to the server and have your private key on your pc!!

This technique the Public/Private Key Cryptography System and send request to and back. So here how we do it:

On Your Pc

=========

1. cd to your home directory

2. ls .ssh/

3. Generate the key pairs

   ssh-keygen 

4. Copy the public key to the server

    scp .ssh/id_rsa.pub youUsername@server.com:

 

on server

========

Login on your server and do the following

1. ls .ssh/

2. cat id_rsa.pub >> .ssh/authorized_keys 

3. rm id_rsa.pub 

Hope it works, if it doesn't do leave a comment and explain the problem, remember i'm still a linux newbie
