Lock SSH access
« on: December 26, 2013, 01:56:00 PM »
Hi All.

Got this NAS 1 month ago.
Upgraded to 1-02b07. (1-03 still not on my country D-Link website).

Very astonished to found that I can access the NAS thru SSH as root and WITHOUT PASSWORD! :o
Once logged in, I can change password with passwd, but it's lost after reboot.

Surely I'm missing something...it's absurd this is by design. :P

Thanx

Ok, SSH is enabled only if Remote Backup service is enabled.

Nontheless, to let root login without a password is a HUGE SECURITY BREACH!!  >:(

This is THE next bug to be fixed, DEFINITELY!

Hi,
any update on this? This bug still seems to be present on 1.03b04.

What's currently the "correct" procedure for installing the fun_plug scripts? Do they interfere with the default servers (ssh, rsyncd)? I really like the rsync feature...

However, it's mentioned here http://nas-tweaks.net/371/hdd-installation-of-the-fun_plug-0-7-on-nas-devices/ that the Remote Backup Services should be deactivated.

Is that still right?

cheers,
boza

I used the same tutorial install fun_plug, and it works well. SSH and rsync still works after the install.

If you don't want to use fun_plug, but still want to secure SSH with a root password, you could properly use part of the tutorial as well. Especially the Change root password section (http://nas-tweaks.net/371/hdd-installation-of-the-fun_plug-0-7-on-nas-devices/#Change_root_password). Here he has a script to store the root password on the NAS, so it's still set after a reboot. Start using the tutorial from the passwd command

My guess is that this will work fine without installing fun_plug.

Edit: After looking at the script I see the you need to change the interpreter from #!/ffp/bin/sh to #!/bin/sh if you didn't install fun_plug
