Step 1: Create public and private keys using ssh-key-gen on local-host
goldenjohn@local-host$ [Note: You are on local-host here]
Generating public/private rsa key pair.
Enter file in which to save the key (/home/goldenjohn/.ssh/id_rsa):[Enter key]
Enter passphrase (empty for no passphrase): [Press enter key]
Enter same passphrase again: [Pess enter key]
Your identification has been saved in /home/goldenjohn/.ssh/id_rsa.
Your public key has been saved in /home/goldenjohn/.ssh/id_rsa.pub.
The key fingerprint is:
Step 2: Copy the public key to remote-host using ssh-copy-id
goldenjohn@local-host$ ssh-copy-id -i ~/.ssh/id_rsa.pub remote-host
Now try logging into the machine, with "ssh 'remote-host'", and check in:
to make sure we haven't added extra keys that you weren't expecting.
Note: ssh-copy-id appends the keys to the remote-host’s .ssh/authorized_key.
Step 3: Login to remote-host without entering the password
goldenjohn@local-host$ ssh remote-host
Last login: Sun Nov 16 17:22:33 2008 from 192.168.1.2
[Note: SSH did not ask for password.]
goldenjohn@remote-host$ [Note: You are on remote-host here]
The above 3 simple steps should get the job done in most cases
That it , please carry on ...with smiles..
