I'm running omv on an odroid HC2 (installed from the omv image on sourceforge). I've been trying to get public key authorisation working (following the procedure in the guide). I have succesfully achieved this on a "standard" omv install (i.e. not arm). The issue I have with the odroid install is that I continue to get "Permission denied (publickey)" errors when attempting to connect (ssh email@example.com -i ~/.ssh/sshremote) . Please note if I enable keyboard interaction then I can login by supplying the password - ssh itself is not an issue, just public key access (and the public key placed on omv is always in rfc4716 format)
So far, as I have this working on another server I have compared:
- cat /var/lib/openmediavault/ssh/authorized_keys/ssh-access-user - exactly the same (I transferred the file and did a diff as well as visual inspection)
- cat /etc/ssh/sshd_config - exactly the same (as are the settings in the webui that influence this file
- the "user" section on the web ui has the same settings (i.e. user is in an rbash environment (also tried bash), groups are "ssh" and "users"
- systemctl list-unit-files | grep ssh output is consistent between the servers
- systemctl status theservicesabove all report similar
At this point I hit google and didn't find anything pertinent to the situation, however, I was inspired to try setting up a home directory for the user so I could try ssh-copy-id, which I did using ssh-copy-id -i ~/.ssh/sshremote.pub firstname.lastname@example.org (sshremote.pub being in rfc4716 format).
Problem solved. Well, more of a workaround. I still don't know why the original method didn't work or what further debugging I can do to get to the root of the issue, (I did try reordering the authorized_keys file location in sshd_config so the omv location was first - which made no difference).
Any help would be appreciated
