Yeah thanks. But even so Mikrotik asks for a password. So I found a different way to do it. Everything is working fine except the DNS logs. Was working since i made changes i think, and DNS logs are not getting in.

wow !! you did a great job. I've implemented it. Firewall data usage is not working for me. You mentioned to use the private key. which one is the private key? all i can see only id_dsa and id_dsa.pub
