testuser = "user for testing"

vi /etc/samba/smb.conf, append the following line:
security = user
username map = /etc/samba/smbusers

[testfolder]
       path = /media/disk/testdir

1. On host A, generate the key.
#ssh-keygen -t rsa

QUOTE:

Enter file in which to save the key (/home/.username/ssh/id_rsa):#press return
Enter passphrase (empty for no passphrase):#press return
Enter same passphrase again:#press return
Your identification has been saved in /home/.username /.ssh/id_rsa.
Your public key has been saved in /home/.username /.ssh/id_rsa.pub.
The key fingerprint is:
38:25:c1:4d:5d:d3:89:bb:46:67:bf:52:af:c3:17:0c [email protected]

Key generation complete.

There is 2 files generated in ~/.ssh/ : id_rsa，id_rsa.pub

2. copy the content of id_rsa.pub (just 1 line) on host A to the file ~/.ssh/authorized_keys on host B.

3. now you can use scp on host A to access host B without being asked for password.

Note: The file id_rsa on host A must be kept.
