Group, Owner, Permissions

Hi,

I've been trying to use WinSCP and OpenSSH using the instructions here: https://winscp.net/eng/docs/guide_windows_openssh_server

However, I was stuck in this part:

Ensure that your account home directory, your .ssh directory and file authorized_keys are not group-writable or world-writable. Recommended permissions for .ssh directory are 700. Recommended permissions for authorized_keys files are 600. Read more about changing permissions.

When I create a .ssh folder, I assign 0700 in the Octal text box. It was created but when I right click->Properties, Octal was still 0777 and Group: - [0] and Owner: - [0]. I believe this is why when I try to connect via public key authentication, I am getting 'server refused our key' error. Also, Checksum is disabled. Am I missing something from the instructions? I am using SFTP.

Thanks!

Thank you martin. One last query. Does having - [0] as Group and Owner boxes have effect on the .ssh folder access? Why was it [0] in the first place? I have been seeing tutorials or even the one in here: https://winscp.net/eng/docs/ui_properties where Group was users[546] and Owner was martinp[1002].

Mine was - [0] and I was logged on in WinSCP as the usual User in my machine (I was the only user). Your response will be much much appreciated.

It's about how a non *nix SSH server presents advanced remote ACL via simple *nix style permissions. Some may try to at least partially present the permissions somehow. Some (what seems to be the case) simply send 0 and ignore any changes.
