Hi Josee,

Try this link on setting up ssh/scp between server without password.

http://bumblebee.lcs.mit.edu/ssh2/

make sure you are using the correct steps for proper version of ssh/sshd.

Hope this helps.

Hi,

You should generate a public key on the source host
cd /your/home/dir
ssh-keygen -t dsa 1024
(don't enter a passphrase)

on the target host go to the copying users' home directory, create a directory .ssh with mode 700 there.
then copy the sourcehost:/home/you/.ssh/id_dsa.pub targethost:/home/you/.ssh/authorized_keys and chmod' it to 600.

afterwards this should work out of the box, or sshd will output it's errors to /var/adm/syslog/syslog.log

good luck :)

Thanks to all we've been able to figure out how to make it work, but I'd like to add one more issue with this :

How can you scp using those public keys with root when sshd_config is configured with "PermitRootLogin no"?

Thanks

[Elmar P. Kolkman]

What do you think yourself?
scp uses ssh to login and then starts a local command to start copying the files through the ssh tunnel. So there is no way to build the tunnel as root if the permitrootlogin is false.
Unless this is not the case on both systems...

You will need to set up your ssh account with SSH agent forwarding activated. Create account keys with ssh-keygen. Use ssh-agent & ssh-add to set up agent forwarding. You'll be asked for the account password / passphrase once. The agent will securely cache passphrase for the lifetime of your current session.
/usr/local/bin/ssh-agent $SHELL
/usr/local/bin/ssh-add
prompt for passphrase >
