Causa
Keyboard-interactive authentication is not supported for sessions when using SPP. The authentication method PasswordAuthentication is not enabled on the target -
Resolución
To validate that PasswordAuthentication is enabled on the target run the command# ssh -o PreferredAuthentications="password" username@127.0.0.1
If PasswordAuthentication is disabled, it will show a permission denied error:Permission denied (gssapi-keyex,gssapi-with-mic,publickey,keyboard-interactive).
If PasswordAuthentication is enabled, it will allow the logon and prompt for the passwordusername@127.0.0.1's password:
To resolve the issue, on the target Asset, ensure PasswordAuthentication is enabled in the sshd_config, then restart SSHD
For example:[root@centos1 ~]# sshd -T | grep -i passworda
Alternatively, use SSH Key authentication instead of Password authentication.
