3 langkah login ssh antar server tanpa password

Langkah 1: Membuat public dan privat keys menggunakan ssh-keygen pada local-host

wa2n@local-host$ [Note: Anda berada di localhost]

wa2n@local-host$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/home/jsmith/.ssh/id_rsa):[Enter key]

Enter same passphrase again: [Pess enter key]
Your identification has been saved in /home/jsmith/.ssh/id_rsa.
Your public key has been saved in /home/jsmith/.ssh/id_rsa.pub.
The key fingerprint is:
33:b3:fe:af:95:95:18:11:31:d5:de:96:2f:f2:35:f9 jsmith@local-host

Langkah 2: Copy public key ke remote-host menggunakan ssh-copy-id

wa2n@local-host$ ssh-copy-id -i ~/.ssh/id_rsa.pub -p 555 user@remote-host
wa2n@remote-host's password:
Now try logging into the machine, with "ssh 'remote-host'", and check in:

.ssh/authorized_keys

to make sure we haven't added extra keys that you weren't expecting.
