Login on your dreambox 7025, 800 or 800 without a password
Start by downloading what we need. That's not much:
2: First Logon
Start PuTTY (from the start menu). PuTTY is also a good telnet client,
and if the Dreambox is fresh from its box or you just flashed a new image,
SSH will not function because you'll need to set a non-blank password first.
So good old telnet is first.
Now select Open and you'll see the login prompt. Enter "root" to log on.
Let's create a safe and difficult to guess password. Make it hard, you'll
never need to type it again. I think. Us the "passwd" command:
Don't close this window yet, we'll need it later!
3: Create a Key
Next is creating us a key. Run "PuTTYGen" and press the Generate button.
Wiggle the mouse until the bar fills up and you'll see a new key appear.
Press "Save private key" to save the private login key. This is only meant for you - it is not intented to be stored on the dreambox, though you might want to store it on a USB stick for external use, e.g. at work. I'm saving it as C:\MyKey.ppk. No need to store the public key. Also, keep this window open for awhile.
4: Authenticate the Key
Next, create the authorized_keys file. In the telnet session from step 2,
Go back to the PuTTY window and paste the text, by right-clicking inside the
window. The key text should appear. Press RETURN to end the input line, and
press CTRL-D to close the file (I usually have to hit CTRL-D twice).
Both windows can be closed now.
5: My first session
Restart PuTTY and load the previous session with the Load button. Don't
double-click, and don't Open it yet. Change the "telnet" radio button
to SSH now. Press Save to save the new setting.
We wish to log on as "root", select Connection/Data in the tree to the
left of the screen. Enter "root" as auto-login username:
In Connection/SSH/Auth, select the keyfile that we saved to disk in step
Don't be impatient... First go back to the Session page, at the top,
and press Save to store all the new settings. Now hit Open (or enter) and
PuTTY should smoothly log on. You'll get a warning that this host is new and
not yet trusted. We trust it now.
Bonus: Access to the WebInterface and more
SSH also supports "port forwarding". This allows you to "tunnel" other connections, piggy-backing on the SSH connection without the need to configure extra ports on your router.
Check out Connection/SSH/Tunnels. Here you can tunnel ports from your local machine to the dreambox or any machine it's connected to.
For each port, enter source and destination in the boxes, and press Add.
Leave the radiobuttons on "local" and "auto".
No password allowed
Even safer! You can configure the dreambox to never allow passwords on
its SSH interface (telnet will still function). To do this, the dropbear
server on the Dreambox needs the
