@FurryNutz. Thank you very much for your reply. I read the whole topic. It sounds like the only working solution is to install a third party add-on (OpenSSH) in order to have access to SSH.
I installed OpenSSH but I can't login either as "root" with blank password or as "admin" with the password I'm using to access the web UI.
Dear fellows don't get me wrong but there are some things I find difficult to understand with this device and I'm bit confused. For example If firmware 1.07 supports SSH what is the point to install a third party addon to have access to it? Is the SSH function of the NAS broken? If it's broken why DLINK doesn't fix it?
Generally speaking I'm getting disappointed with this device and DLink itself. I have bought DNS-320L about 2-3 weeks now and everything about it looks and feels completely amateurish. I bought this NAS as a "ready to use" solution to do a certain job in my office not to hack around. I didn't bought it as a hobby project. (I happily use Raspberry PI for that). Please don't get me wrong I really appreciate everybody's support & help around here. I just don't understand what DLink consider an off-the-shelf product.
All I wanted was three things - that according to its specs were available:
1. Schedule FTP downloads to the NAS. In order to get the backup files from my web servers. (Works. The reason I preferred this NAS)
2. Taking PCs' backups to the NAS (Woks)
3. Taking periodic backup of the NAS to USB connected HDD for off-site safe keeping. (Not Working)
Do you see an exotic requirement above? Do you honestly believe that I have raise the bar of expectations too high?
I could understand if I have to hack this think to run let's say... a Wordpress blog on it or a phpBB forum for fun, but I really don't get it why I have to "hack" this thing to get a backup of my files...
PS. I see that there is built-in functionality to run forums and blogs
