ssh_host_rsa_key.pub file is missing

[topias5]

I'm trying to create a new replication task to remote Freenas machine but I've had some problem with permissions.
There's an error in the replication task "Permission denied, public key, password". I re-check rsa keys and figured out ssh_host_rsa_key.pub file is totally missing at /etc/ssh folder. A private file ssh_host_rsa_key is exist (without .pub extension).

How can I recreate these keys? What could be the reason why the key is missing? I have done a succeed replication task for other computers already and I didn't have this kind of problem.

Which version of FreeNAS? Please post a listing of /etc/ssh either in code tags or as a screenshot.

Hi,
Version is FreeNAS-9.3-STABLE-201503071634

I have built another system with the same Freenas source and everything works properly there, so there must have been some action in the current system what has caused a loss of the public key file.

That is weird. Out of curiosity, if you go to System -> Update -> Verify Install does it make note of the missing file?

As for a solution, do you have to use RSA keys?

 

[topias5]

The system didn't find any missing files by Verify Install -tool. I updated the latest version from System > Update to FreeNAS-9.3-STABLE-201503150158 and the public key file is still missing.

I would like to create a replication task where the machine would be the PULL side and according to the guidance of Freenas the missing file should be used as the public key for the operation.

 

[dlavigne]

This command (from Shell) should regenerate the hostkey: ssh-keygen -t rsa

 

[topias5]

The command will generate id_rsa and id_rsa.pub files under /root/.ssh folder. Can I use the generated public file and copy it to /etc/ssh/ssh_host_rsa_key.pub?

 

[dlavigne]

Yes. Make sure it does not have a passphrase.

it is a year later and I see the same issue in
Build FreeNAS-9.10.1 (d989edd)

Does this mean 9.10 is not ready for consumption yet?

found the issue - to turn the sshd on you cannot select left side bar menu - this fails if sshd is not turned on with the top pulldown menu "services". This top one generates the keys.
