Question
FreeBSD 13.2 post-install : impossible login

Asked by GIORGIO MICHELI
While FreeBSD is not longer listed in available OS i follow instructions to upload a custom image, that i found at https://bsd-cloud-image.org/ ; anything goes but at first login i get
Server refused public-key signature despite accepting key.
that, as far as i know, depends on a sshd_config parameter.
to walkaround the matter i try to set password login at droplet creation time, but it is denied.
thus even recovery console, that require the root password, became unusable.
so the question is : must i create a custom personalized image? if yes the matter moves to : can i use an existing FreeBSD 12 droplet to build the needed FreeBSD 13 image with sshd_config adequate to D.O. login requirements?

You can use your existing FreeBSD 12 droplet to build the needed FreeBSD 13 image with an sshd_config that matches DigitalOcean’s login requirements. Ensure to set your
sshd_configfile with ‘PermitRootLogin prohibit-password’ to allow key-based authentication.If you are still getting the same error, Server refused public-key signature despite accepting key, try regenerating the SSH keys on your server or your local machine, and re-adding them.

Hi there,
Indeed, as you mentioned you could try creating a customized FreeBSD image where you’ve pre-configured the
sshd_configwith the correct parameters for public key authentication.Alternatively, if you already have a FreeBSD 12 Droplet, you could take a snapshot and then spin up a new Droplet based on that snapshot.
After that you could upgrade the new Droplet to FreeBSD 13 as described in the FreeBSD docs here:
Hope that this helps!
Best,
