  • public ssh key, cek pastikan ada file id_dsa.pub
~/.ssh
  • kalau belum ada id_dsa.pub di ~/.ssh lakukan
chmod 700 ~/.ssh
ssh-keygen -t dsa
ssh-keygen -t rsa
  • copykan ke remote server
scp ~/.ssh/id_dsa.pub remoteuser@remoteserver.com:
scp ~/.ssh/id_rsa.pub remoteuser@remoteserver.com:
  • di remote server append content public key id_dsa.pub ke ~/.ssh/authorized_keys dan delete file id_dsa.pub
cat id_dsa.pub >> .ssh/authorized_keys
cat id_rsa.pub >> .ssh/authorized_keys

Atau sekaligus lakukan dengan cara

ssh -l remoteuser remoteserver.com 'mkdir .ssh'
ssh -l remoteuser remoteserver.com 'touch ~/.ssh/authorized_keys'
cat ~/.ssh/id_dsa.pub | ssh -l remoteuser remoteserver.com 'cat >> ~/.ssh/authorized_keys'

jangan lupa delete id_dsa.pub dari home directory di remote server

selanjutnya kita dapat login tanpa di tanyakan password

ssh -l remoteuser remoteserver.com
ssh remoteuser@remoteserver.com


Alternatif Lain

The whole process is much easier if you just use:

ssh-copy-id [-i [identity_file]] [user@]machine
ssh-keygen -t dsa
ssh-keygen -t rsa
ssh-copy-id user@machine
