Keychain on DS212+ DSM 4.0

[jaanus_k]

Hi,

I need to download backups from remote server using shell script and SFTP (cron job).
Problem is that I can't give password with command : "sftp some_user@some_server"
I tried to install Keychain to my DS212+, but it doesn't work and I don't find any manual how to configure it correctly on Synology NAS.
