[maemo-developers] [maemo-developers] ssh key failure

[From: Christine Liu]

i discovered what works -
i need to generate a dsa key, NOT an rsa key
and if i want to ssh into the nokia unit, the correct file is authorized_keys.

now that i'm looking it's right there in the wiki:
http://www.maemo.org/maemowiki/InstallSsh

(the 'note' about keys is the stickler)

thanks - i must have glossed over, this technicality of rsa vs dsa is
a little arcane to me.
best, christine

4.4. Generate a dsa-key for outgoing connections
As user, generate a dsa key for outgoing connections

ssh-keygen -t dss -f /home/user/.ssh/id_dsa
The above command will output your public key to the tty, but does not
save it. Capture the whole key (up to, but not including, the
fingerprint:...) in your desktop's terminal, save it to a file called
id_dsa.pub and scp that file to /usr/home/.ssh/id_dsa.pub on your 770
(optional). More importantly, append that key to
~/.ssh/authorized_keys on any machine you want to ssh into from the
770.

Now, you should be able to open the x-terminal on the 770, and just
type ssh me at example.com and you will be ssh'ed in. Similarly, you can
scp file me at example.com:file. You can turn off the
PasswordAuthentication: yes flag in sshd_config that you set in the
above step.

4.5. A note about keys
The Dropbear ssh daemon seems to only accept RSA keys for incoming ssh
connections. However, it can use DSA for outgoing keys, which the
example above shows.
