Synology root Login aktivieren (ssh)

After getting the DSM 6.0 upgrade, I’ve become unable to login as root using SSH, even though I’ve been able to do it before the upgrade (DSM 5.5 or something like that).
The solution:
1. SSH to machine as admin user.
2. Enter command “sudo -s” and providing admin password.
3. Enter command “synouser -setpw root “.
Now I’m able to logon as root using SSH again, and I didn’t have to mess with telnet.
