[maemo-developers] Installing SSH

[From: Larry Battraw]

  Hi Jeff, I'm guessing from the steps you're trying to take that you
want to use SSH to access your n800.  Now adding your public key from
your Ubuntu system to the ~/.ssh/authorized_keys file is only
necessary if you don't want your n800 to ask you for a password when
logging in.  If you're trying to log in for the first time as root
(ssh root at x.x.x.x where x.x.x.x is your n800's IP)  and it keeps
asking you for a password (which you don't know ahead of time) it's
"rootme" for the root account.  No idea what it is by default for the
user account.  Once you can log in as root you should immediately
change the password on the n800 via the "passwd" command.

  If you'd still like to skip the password prompt when logging in from
a specific system that's when the authorized_keys file comes into
play.  First, verify you have a ~/.ssh/id_dsa.pub file on your Ubuntu
system; if not, run the command "ssh-keygen -t dsa".  Now copy the
~/.ssh/id_dsa.pub file from your Ubuntu system to your n800 into /tmp
(scp ~/id_dsa.pub root at x.x.x.x:/tmp).  Once you log in then type "cat
/tmp/id_dsa.pub >> ~/.ssh/authorized_keys".

  The above directions assume you'd like to log in as root all the
time; perhaps not the best idea.   To be able to log in as the "user"
account just type "cat /tmp/id_dsa.pub >> ~user/.ssh/authorized_keys.
Thereafter you'll be able to log in as the "user" account via ssh
user at x.x.x.x.
