Dropbear SSH server with key authentication
I have a WL-500g with 1.9.2.7-5a firmware. I Use the built-in dropbear SSH server to SCP images from the router to my dedicated server. The SCP command is run form my server, and not from the router.
My problem is that the SCP command is run automatically by a cron-job, and the SCP command requires a password. I have read quite a lot on the internet, and found out that i need to authenticate the machines via no-password keys placed in the authorized_keys file on the server (the WL-500g).
How do I do that on WL-500g? Do dropbear and OpenSSH use the same keys (don't think so..), and how do I convert/create them? And where shall i place the authorized_keys file, and how does it look like on a dropbear server?
I hope that someone will help me.
Thanks.
