SSH keygen and login problem

[a bv]

 Hi,,

For my file transfer script i want to use scp without password. Here
is nearly what i have done:
1- I logined to my Checkpoint (which is Redhat based and the one who
is source) with my personal user and gave expert command  to have root
permissons.
2. Changed directory to /root/.ssh and gave ssh-keygen -t dsa and
created the key pairs.
3 I copied yhe public key to my home folder at the remote server  like

scp ~/.ssh/id_dsa.pub myuser at remoteserver:/home/myuser.ssh/authorized_keys

4. Then i copied this authorized_keys to the /root/.ssh.
5 then tried to send a sample file from my Checkpoint box to remote server
with scp but it requested me to enter a password.

how can i fix this ? then ill adapt my scirpt to this
regards.
