Jika anda ingin agar setiap kali menjalankan perintah ssh ke remote komputer linux tidak perlu mengisikan password, ikuti langkah-langkah berikut.

Langkah yang pertama, kita harus membuat Public dan Private RSA Key pada komputer kita. Tekan enter di setiap konfirmasi.

# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
6b:a1:e4:4d:96:10:a3:5f:92:bc:33:f5:c8:4d:3f:c3 root@immux-laptop

Selanjutnya kita copy kan key hasil generate tadi ke ssh server.
