terus bagaimana kalo saya pengen login ke ironhide.immteknik.org tanpa kata kunci? cukup mudah sekali apabila anda ingin menghemat waktu, bayangkan bila kata kunci nya puanjang? wew lama bangetz: caranya seperti ini:
1. buat kunci ssh di sisi server

ssh-keygen -t dsa

2. simpan sebagai id_dsa

3. salin berkas id_dsa ke komputer target (misal nya di /tmp

scp .-r ssh/id_dsa.pub root@ironhide.immteknik.org:/tmp

4. kemudian login di komputer target

5. buka berkas tersebut

ironhide:/tmp # cat id_dsa.pub >> ~/.ssh/authorized_keys

6. log out dari target, dan coba login lagi dari server

server:~# ssh root@ironhide.immteknik.org
