scp without password

steven chang_1 — Mon, 09 Feb 2004 03:33:24 GMT

hello :

I am trying to scp from solaris 8 to redhat 8, and openssh version running on solaris 8 is
OpenSSH_3.6.1p1 redhat 8 is OpenSSH_3.4p1,

I generate the public/private key for solaris and ftp the id_dsa to redhat and use the id_dsa.pub to generate authority_keys file to redhat 8 . I already put ssh-agent start script in the .profile on the solaris 8 and auto give the passphrase through ssh-add,
but I need update ssh-add pass phrase every time when I login the solaris. Now I want to write a script to scp a tar file from redhat 8.

How can I auto give the passprase with interactive giving through the terminal input.That is how can writing a script to scp with giving any imformation and run this script in the crontab. Thank you very much

If I let the pass pharse empty when generating the public/private key , my goal would be achieved.

run
ssh-keygen on Solaris. Then when prompted for password just press enter.By default the public key file is saved under ~/.ssh/id_rsa.pub

copy that file to redhat and place it content
in /root/.ssh/authorized_keys (to be able to ssh/scp as root)
like for example
less id_rsa.pub >> /root/.ssh/authorized_keys

Best Regards..

This doc will help.

The X stuff can be replaced with the cat >> command
