Hi, Thanks, that was exactly it. To add a few bits of info: You first must get a pair of private/public keys ssh-keyget -t rsa for the OI user to run the zfs send. Um, yes, sorry, I assumed that you already did this ;-) I suppose you could use password login for root on freenas, but freenas is set up to use rsa key controlled login for replication. So this way probably has been tested a lot more. I don't know whether receiving a data stream via SSH using a password will work at all; I'm normally using only public key authentification...

Thanks, that was exactly it. To add a few bits of info: You first must get a pair of private/public keys ssh-keyget -t rsa for the OI user to run the zfs send. Then copy the public key from ~/.ssh/id_rsa.pub on OI to the user root (or other user with admin privs) on freenas.

To test run ssh root@freenas_address ls When it works, run pfexec zfs send -R Tank/dataset@snapshot | ssh root@freenas_address '/sbin/zfs recv Tank/Media/name' on OI zfs on freenas is in /sbin, I suppose you could use password login for root on freenas, but freenas is set up to use rsa key controlled login for replication.
