comment How to setup password-less ssh with RSA keys
I found an article explaining how to disable password login for root in dropbear by editing the /etc/default/dropbear configuration file. But that file doesn't exist on my system. (source: cybermilitia.net/2009/02/28/dropbear-on-debian)

comment How to setup password-less ssh with RSA keys
it is possible as I have one box that is currently doing it. "box1" in the question is a host computer and there are actually multiple "box2's". box2 is an embedded system running dropbear. I currently have 1/3 of these working fully (that is I am able to passwordlessly communicate from box1 to box2 and from box2 to box1). So it is possible, but I can't find a key or configuration difference between them.

= is not required as I have tested between two Linux boxes running OpenSSH and they both work without any = in the public keys. Additionally, it is working from dropbox to OpenSSH without a = in the file.

@ire_and_curses Very interesting post, thanks. I tried to limit it to protocol 1 and generate new keys for rsa1. Not only did that not work, but it also broke the dropbear configuration. So box2 returns connection to root@box1 exited: Incompatible remote version 'SSH-1.5-OpenSSH_5.5p1 Debian6'

@Gilles dropbear is started by the following: start-stop-daemon -S -q -p /var/run/dropbear.pid --exec /usr/sbin/dropbear

I have verified on both boxes that there is no extra space at the beginning or the end of the authorized_keys file. However, There is also no "=" sign followed by the key name you are referencing. The format of my file is: ssh-rsa $KEY root@boxn Is this incorrect?

Also added debug output as it might be insightful.
