Just testing vertical backup on my ESXI server (6.7 - free license).
Backing up over SFTP with password works fine however attempts to use ssh keys fail with the following error:
[root@esxi:/vmfs/volumes/5950cec4-139b2712-ec87-0cc47a9a5c3a/verticalbackup] ./vertical list
Vertical Backup 1.4.3
duplicacy@nas.xxxxx.org’s password (leave blank to choose public key authentication):
Enter the path of the ssh private key file:nas.ssh
Enter the passphrase of the ssh private key file:
Failed to create an SFTP client: Authentication failed.
However it works find from the same box using ssh:
[root@esxi:/vmfs/volumes/5950cec4-139b2712-ec87-0cc47a9a5c3a/verticalbackup] ssh -i nas.ssh duplicacy@nas id
Enter passphrase for key ‘nas.ssh’:
uid=1001(duplicacy) gid=1001(duplicacy) groups=1001(duplicacy)
Tried using keys with and without passphrases. Verbose output gives no extra information.
Logs on nas box (Raspbian GNU/Linux 10 (buster)) :
Jul 22 12:48:05 nas sshd[11426]: Connection closed by authenticating user duplicacy 192.168.1.72 port 16183 [preauth]
Any ideas?
Thanks
