SSH keys with dropbear?
Is there a trick to getting SSH keys working with dropbear? I've only used them with the OpenSSH sshd before, and I can't seem to get it to work.
On the Kindle, in /tmp/root aka /var/tmp/root (root's home), I have:
[root@kindle root]# ls -ld .ssh drwx------ 2 root root 60 Oct 6 22:49 .ssh [root@kindle root]# ls -ld .ssh/* -rw-r--r-- 1 root root 391 Oct 6 22:54 .ssh/authorized_keys
I can post the full output of ssh -vvv if needed but there really doesn't seem to be much of use there, the relevant bit is:
debug1: Next authentication method: publickey debug1: Offering RSA public key: /home/eli/.ssh/id_rsa debug3: send_pubkey_test debug2: we sent a publickey packet, wait for reply debug1: Authentications that can continue: publickey,password

Because root's home is in a tmpfs partition, I patched dropbear to always look for the pubkeys in a single place: usbnet/etc/authorized_keys (and tweaked the permission checks to not die horribly because it's a vfat partition).
It handles files formatted for OpenSSH, so you shouldn't have any trouble with a key generated by openssh's tools (be it a rsa or dsa key) . (It works fine with openssh's ssh-agent too).
