admin login with ssh fails in restored configuration

[amnixed]

Hello,

I have restored a saved configuration from an SG-5100 to a non-Netgate device. With some minor adjustments (interface names) restoring from backup went well.

The SG-5100 is a production device, the non-Netgate device is a standby spare.

However, in the restored configuration, login with ssh as admin/[password] fails:

sshd 	53894 	error: PAM: Authentication error for admin from 10.61.70.200 

But login through the web interface works fine (same credentials, of course):

php-fpm 	337 	/index.php: Successful login for user 'admin' from: 10.61.70.200 (Local Database)

Could someone please explain?

Try removing your ssh known hosts file on the device you are running ssh from, the ssh key has changed.

I do get prompted for password, and then you can see the "Authentication error" in the log file - so this past the ssh fingerprint detection.
