Hello,
First post and have an N810 coming tomorrow. I have spent the last number of weeks researching the N800/N810 and did not quite come across an answer to a question I have (I did search this site but did not find an exact answer). First, I am a developer and understand the "root" id in UNIX/Linux and that it should be locked down. Now for the question: if I do not install openssh or dropbear, do I really need to change the root password (i.e., will the N810 be secure)? I am thinking that the N810 is really an "appliance" and that out-of-the-box it should be secure. I am not really against changing the root password, I am just going out of town the day I get the N810 and most likely will not have a chance to do it.
Also, does changing the root password cause any issues with installing software? I am guessing that OS2008 uses "root" for various things and am not sure how it gains access to that account (if the password is changed).
Last question - can someone give me a few sentence reason to install openssh? I read a lot about what you can use it for but was looking for a general benefit of having it.
Thanks
Jay

You can check /etc/sudoers to see what tasks is allowed to execute.
Changing password will not affect the normal operation.
Besides, ask I know, OS2008 lock the account "root" by default. That mean you cannot login with any password. You can check if there is a "!" after "root:" in /etc/passwd

Change the root password if you install the SSH server. Or you may be in for a surprise at some wi-fi hotspot!
(Yesterday I read a posting that said, IIRC, that the latest open-ssh package actually prompts you to change the pw during post-installation. Don't take my word for it though.)
EDIT: If OS2008 locks the root account (the user account is locked in OS2007 already) then you'll have to set up RSA authorization to use the ssh server at all. Anyway, if it's locked it's safer.

Uhmm what kind of surprise?
I'm curious about that!
E.g.
$ ssh -l root 192.168.1.12 rm -rf /
Password:

boom.

Ah ok 
I thought root account was locked on OS2007.
Also PermitRoot was set I guess.
Good that I changed it then!

I use Windows, but at work where there is no wifi. What can I access via USB? All I see is the folder with the maps.
At home I have wifi, but I'm on a Mac. Anyone have software recommendations?
