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 [email protected]:/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
