Simple step by step guide to getting Root Access on a Synology DiskStation

I’ve read this article, and decided to save the text – just to be sure.

What I did was this:

Getting root access to the Synology after the DSM 6.0 update is solved by doing this.

If you get the WinScp, then you alse get the PuTTY and PuTTYgen.

I’ve used the Config File Editor as explained.

Afterwards I logged into WinScp and used the private key under Advanced–SSH—Authentication.

You’ve of course chosen a very difficult admin/root password for your Synology diskstation – but now everytime you want to connect with Putty you need to type in that long chain of characters, numbers and symbols.

Why not use a a keypair?

1. 1. Download PuTTY and PuTTYgen (or just get the installer, everything is in there) from here.
   2. Generate a keypair with PuTTYgen (Parameters: SSH-2 RSA)
   3. Save the private key as “myprivatekey.ppk”
   4. Copy the public key to the clipboard. Looks somewhat like this:
      ssh-rsa AAAAB3NzaC1yc2EAAAABJQAAAIEAzP4MR3lkCD2pa7nwT3NMjjDBMmEuJ4exW4GKBBP+okArZ/IrjbLIpdh8ahpfgjh8kM//OVUGeRa1GigzcCuGzIa2YfS7L4Q9cbUUWFwIu2hGV3ZpJ2xDZExaaLH90Vw+ZBaozD2OI4FZ1Dqh8Bj29SQqIIbmxf/ASyTmXHZCbQk= rsa-key-20130414
   5. Connect to your diskstation with PuTTY
      diskstation:22
   6. Login as root
   7. Edit the SSH config with
      vi /etc/ssh/sshd_config
   8. Look for the following lines
      #RSAAuthentication yes
      #PubkeyAuthentication yes
      #AuthorizedKeysFile      .ssh/authorized_keys
   9. Change them to this (by hitting “x” when the cursor is over the # and hitting ESC, then typing :wq ENTER)
      #RSAAuthentication yes
      PubkeyAuthentication yes
      AuthorizedKeysFile      .ssh/authorized_keys
   10. Go to /root and create the .ssh folder
       cd /root
       mkdir .ssh
   11. Edit the keyfile
       vi /root/.ssh/authorized_keys
   12. Press “i”
   13. Paste your public key (by right clickking on your mouse) and save the file (Hit Esc, type :wq, hit Enter)
       ssh-rsa AAAAB3NzaC1yc2EAAAABJQAAAIEAzP4MR3lkCD2pa7nwT3NMjjDBMmEuJ4exW4GKBBP+okArZ/IrjbLIpdh8ahpfgjh8kM//OVUGeRa1GigzcCuGzIa2YfS7L4Q9cbUUWFwIu2hGV3ZpJ2xDZExaaLH90Vw+ZBaozD2OI4FZ1Dqh8Bj29SQqIIbmxf/ASyTmXHZCbQk= rsa-key-20130414
   14. Set the access-rights to the file
       chmod 700 /root/.ssh
       chmod 644 /root/.ssh/authorized_keys
   15. Disconnect with
       exit
   16. Open Putty again and make the following settings
       
       Hostname: or
       Port: 22
       Connection type: SSH
       Connection->Data->Auto-login username: root
       Connection->SSH->Auth->Private Key: Your Keyfile
       And save the session as <sessionname>
   17. Create a new shortcut on your desktop with the following target
       "C:\Program Files (x86)\PuTTY\putty.exe" -load "sessionname"
   18. Finished. From now on you can connect by double-clicking.
