How To Set Up SSH Keys (Easy way)

Step 1: Create the RSA Key Pair:

In your computer:

ssh-keygen -t rsa

Step 2: Store the Keys and Passphrase: (Optional, you car omit this pass with enter)

Enter file in which to save the key (/home/demo/.ssh/id_rsa):

Enter passphrase(empty for no passphrase):

Generating public/private rsa key pair.
Enter file in which to save the key (/home/demo/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/demo/.ssh/id_rsa.
Your public key has been saved in /home/demo/.ssh/id_rsa.pub.
The key fingerprint is:
4a:dd:0a:c6:35:4e:3f:ed:27:38:8c:74:44:4d:93:67 demo@a
The key's randomart image is:
+--[ RSA 2048]----+
|          .oo.   |
|         .  o.E  |
|        + .  o   |
|     . = = .     |
|      = S = .    |
|     o + = +     |
|      . o + o .  |
|           . o   |
|                 |

Step 3: Copy the Public Key to the remote host (where you want to access without password):


In you computer:

ssh-copy-id <user>@<remote-host>

Step 4: Try access  to your remote host

In you computer:

ssh <user>@<remote-host>

or with graphic interface:

ssh -X <user>@<remote-host>
