I installed openssh (server and client) and tried setting up public key authentication to login into the N900 from my Ubuntu machine, but it's not working. I generated the keys in Ubuntu with ssh-keygen, copied id_rsa.pub to /home/user/.ssh/authorized_keys in the N900 and it still asks for password when I try ssh user@N900_ip from the Ubuntu machine. I made sure the folder .ssh is chmod 700 in the N900 and the file /home/user/.ssh/authorized_keys is chmod 600. (Public authentication works using the N900 as client to login into Ubuntu.) I also cannot find the ssh logs in the N900 itself. I thought it would be /var/log/auth.log, as in Ubuntu, but it's not. Any suggestions? I apologize it this has been discussed in some other thread.
