rsync FreeNAS to raspberry-pi via SSH

[Juergen]

Hi,

I've some issues regarding rsync from my FreeNAS to a raspberry-pi.

The rsync-task is as:

Path: /mnt/volume01
Remote Host: [ip of the pi]
Remote SSH Port: 22
Rsync mode: Rsync over SSH
Remote Path: /media/ixbackup (exists on the pi)
Direction: Push
...
User: user1 (exists both on FreeNAS and pi)

I created a pair of keys on the FreeNAS:
user1@freenas:~ % ssh-keygen -t ecdsa

and copied the public key to the pi:
user1@pi ~/.ssh/id_ecdsa.pub

when the job starts it produces the following output:
Nov 1 13:12:00 freenas cron[39072]: _secure_path: /mnt/volume01/.login_conf is world writable
Nov 1 13:12:01 freenas rsync: No ECDSA host key is known for 192.168.178.23 and you have requested strict checking.^M
Nov 1 13:12:01 freenas rsync: Host key verification failed.^M
Nov 1 13:12:01 freenas rsync: rsync error: unexplained error (code 255) at log.c(235) [sender=3.0.9]

and that's it.

Any suggestions what's going wrong or what's missing?

Thx, bye
J.

I created a pair of keys on the FreeNAS:
user1@freenas:~ % ssh-keygen -t ecdsa

Quoting the documentation (Configuring Rsync over SSH Mode Between Two FreeNAS® Systems):
"FreeNAS® supports the following types of SSH keys: DSA, and RSA. When creating the key, specify the type you wish to use or, if you are generating the key on another operating system, select a type of key the key generation software supports."

Hi,

it works - with ecdsa-keys. I must have made something wrong with the keys earlier.

Now I deleted all of my keys, both on the FreeNAS and the pi. Then I generated new pairs of ecdsa-keys and pushed the pubic keys from pi to FreeNAS and from FreeNAS to pi. For some reason the ssh-copy-id script doesn't work, I had to copy the keys manually: cat ~/.ssh/id_ecdsa.pub | ssh $REMOTE_HOST 'umask 077; mkdir -p ~/.ssh; cat >> ~/.ssh/authorized_keys'

Now I discover the next issue: initial rsync of 350 GB Data over the FastEthernet-Port of the pi to its USB-2.0 external drive takes a bit

Cheers!
