XSI-PRO 11.2.15 Error: The Authenticity of Host Can't be established

Problem:
Backups fail. Keys cannot be exchanged. If anyone has observed this behavior and can provide a work-a-around that would be appreciated.

+++++++++++++++++++++++++++++++++++++++++++++

Source server EXSI 6.7U3. New install of 11.2.15 code. License key added from website to root directory.

+++++++++++++++++++++++++++++++++++++++++++++

Step #1
From GUI: Key Exchange for Transparent communications fails with message:

The Authenticity of  Host (xxxxx) can't be established. RSA Key Fingerprint is SHAxxxxxxxxxx. Are you sure you want to continue connecting (yes/no)? yes

Password:

sed: unmantched '/'

Cannot find an authorized_key file at xxxxx

Tip: you might need to install additional Openssl components, or just create the file for your OS, it usually requires 0600 permissions.

Killed

Observation: No text added to /etc/ssh/keys-root/authorized_key

Step #2
Executed link-srv=1.2.3.4=22
This command succeeds with text added to /etc/ssh/keys-root/authorized_key

Step: #3
Executed backup
App requested password ... very odd.

Step #4:
Backup fails:

stty: standard input

Re: XSI-PRO 11.2.15 Error: The Authenticity of Host Can't be established

Don't even try to perform a backup from one host to another over IP if you haven't exchanged keys succesfully.
You have plenty of typos in your post, this is misleading because may lead others to think that you are mistyping things in your terminal.

Not "authorized_key" but authorized_keys
Not "link-srv=1.2.3.4=22" but --link-srv=1.2.3.4:22

The exchange key process is extremely simple and doesn't involve anything but two functional OpenSSH servers able to communicate. Once this is possible your public (c)XSIBackup RSA key will be added to the remote authorized_keys file at the remote end, that's all from a conceptual point of view.

You are clearly being denied access to the remote system

Permission denied (publickey,password,keyboard-interactive)

Thus, any further attempt to perform a backup without previously fixing that issue will fail.
Forget about anything else and focus in running this command from 192.168.1.48.

./xsibackup --link-srv=192.168.1.70:22

Run it and paste whatever you get.
