Easy Root Access
Easy Root Access
This method for root access has turned out to be by far the simplest and most efficient.
- Netgear Stora, Seagate GoFlex Home or Medion Lifecloud 2-bay NAS unit
- Computer with SSH Client
- Network connection
Located the Product Key for your unit it will be in the form of XXXX-XXXX-XXXX-XXXX, Located both on the CD Jacket and the bottom of the Netgear Stora Unit.
From a Linux Terminal type:
Where USERNAME is your user name (note: all lower case!) on your stora unit, YOUR_IP_ADDRESS is your Stora ip address on your network, and XXXX-XXXX-XXXX-XXXX is your Product Key.
Note: The Product Key must be all caps.
You should be presented with a password prompt at this point, simply type the password for the account name you used to log into the Netgear Stora.
Getting started - with Windows XP/Vista/7
If you're doing all this from a windows computer:
First download PUTTY.exe (an SSH client) from http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html Instead of entering all the above in one line, run Putty and connect to the IP of your Stora on port 22, then enter the username and password separately when prompted exactly as explained above (i.e. USERNAME_hipserv2_netgear_XXXX-XXXX-XXXX-XXXX). You can save the settings in putty so you don't have to type the username every time (look under Connection > Data > Auto-login username)
After logging in everything works the same as a Linux SSH client, you can do everything from windows if you want!
The "hipserv2_netgear" part may be different for some users, although I suppose is the same for everybody, if you already hacked your Stora using other ways I'd ask you to check the "/etc/oe-release" and post here the DistName line and we'll try to figure it out. (see also: Original forum post)
For Seagate GoFlex Home use seagateplug, e.g.:
For Verbatim MediaShare use verbatim, e.g.:
For ICYBOX IB-NAS6210 use Raidsonic, e.g.:
note: IP found to be unnecessary
For Medion Life P89634 (MD 86783) and MEDION LifeCloud P89654 MD 90224... use medion, e.g.:
note: the product key is found on login page behind über Medion LifeCloud
To gain root control type, after login:
sudo -E -s
Again type your account password, you'll probably get a: "audit_log_user_command(): Connection refused" but it doesn't matter, you'll get the root prompt!
Note: All administrative Stora user accounts will have Sudoer access.
There's another way to login concatenating the username with the string "_axsync_" but it allows you to issue only "mkdir" and "rsync" commands.
If your initial account name contains a '-' (and possibly other allowed punctuation) such as
stora-admin then you may get:
stora-admin is not in the sudoers file. This incident will be reported.
If this happens, try adding a new user with the web interface, making sure you click the 'Create as administrator' checkbox and use that user instead.
Now that I have root access I notice that
stora-admin was not included in admin group unlike my previous stora. Perhaps the default account is no longer an admin, or punctuation matters.
Basically Netgear, or more probably Axentra, ships his software with a modified version of SSHD that disallows regular user access, except for "root" and "apache" users, what it does is basically changing the logging username by substituting the first character with a "0" so it doesn't match with the list of allowed users inside the /etc/passwd.
The SSH Deamon leaves a "backdoor" open, which basically is: if your username is appended with the above string, this substitution doesn't take place, and you can login normally.
Where to go from here
- Enabling the Root Account - Allow ssh access as root user.
- sshd substitution - Replaced sshd with a fixed one allowing normal ssh access for user accounts.
