SFTP (or SCP) access for users?

perler · 3. April 2015

SyncBackPro offers what they call SFTP support (port22), which I think is rather SCP (?): http://screencast.com/t/4SZ5w1Zf - problem is, that I cannot conect via private/public key pair.

as I can't find an authorized_key file in the users home directory I don't really expect this to work and wonder if this is even a feature?

Un the users section you can define authorized keys per user. Just click a user at the bottom you can paste the key.

that's what I did. ok, so this is a feature? where is the publc key stored and should I be able to do a

Code

ssh user@host.com

for testing purpose?

Public and private keys are stored here:

/home/username/.ssh/

or

/root/.ssh/

..which they are not. that's what I'm asking about

Code

root@ncc002:/media/ed9575a9-7eea-48aa-a55b-277a6e638013/home/theuser# ls -lisa
total 20
718274566 4 drwxr-xr-x 2 theuser users 4096 Apr  3 10:31 .
718274561 4 drwxrwsr-x 4 root       users 4096 Apr  3 10:31 ..
718274568 4 -rw-r--r-- 1 theuser users  220 Jul 13  2012 .bash_logout
718274567 4 -rw-r--r-- 1 theuser users 3392 Jul 13  2012 .bashrc

You have to create them and put them there.

Ok, I was under the impression, that this http://screencast.com/t/BGgu688YC would handle this...

By default there is a public and private key created for the root user. But password authentication is still enabled. Most people who use this create new keys.

I looked at backsync pro and it does not create keys. There are utilities that will do it, or you can do it in command line. I don't use key authentication. davidh2k and subzero79 are best to ask questions on this. Here is some general info...

thanks, the problem is not the keypair creation, we have the keys we want to use, I was just wondering why we have a UI for entering the public key, but it isn't stored at the place it should go (ie ~/.ssh/authorized_keys)

tekkb · 3. April 2015

The file is specified in the /etc/ssh/sshd_config, AuthorizedKeysFile. You can use either method I believe.

Check this location:

/var/lib/openmediavault/ssh/authorized_keys

perler · 3. April 2015

there they are, thanks!

now I wonder if they are used by regular ssh logins (ie ssh theuser@server.com) or only by SCP/SFTP connections.

I've only worked on openssh for stuff like xming/xwindows/x11 forwarding. Sub or David will probably answer your questions later. We all have different interests.

perler · 3. April 2015

sure, thanks.

subzero79 · 3. April 2015

You have to add the user to ssh group to authorize access.

perler · 3. April 2015

ok. thanks, this works, but unfortunaely, the user ends up in a different directory than when logging in by ftp. but I got the grip now, thanks.

Jetzt mitmachen!
