SSH Keys and rsync

[jvande]

Ok,

Kind of a newbie question here, but I've been looking for about 4 hours now trying to figure out how to do this:

I have a USB HD hooked up on /mnt/BACKUP I'd like to remote SSH into a server and rsync files on the remote server to my USB HD. (a backup system). I can SSH into my router and SSH into my remote server (HOSTGATOR). When I try to rsync, it gives an error that it needs to have SSH authentication set up. I've got a public and a private key generated by the remote server, but where do I put the keys? I can generate new keys from the router (Merlin's latest build) as well, but where do I put those keys on my remote server? I'm a little confused and am having a hard time finding information on dropbear usage. Are there any other alternatives to what I'm trying to do? Is there a tutorial or walk-through on ssh key installation? Is there a way to rsync without SSH (I know its not as secure).

Thanks in advance.

jvande,

Dropbear is funny about what keys it can use, so you need to generate the keys on your router by running: dropbearkey -t rsa -f ~/.ssh/id_rsa
Then put the publickey on your hostgator server. When you issue the rsync command you will need to pass the following arguments to specify the key location: -e "ssh -i ~/.ssh/id_rsa"
