That looks promising, thanks for noting it and expanding my understanding of 
one the parameters I've just glossed over so far because it seemed out of my 
league. I'll give this a try as well at some point. As I noted in another post, 
enabling root on the mac and copying the ssh key to it got things going before 
you suggested this.

Yes I did, though a little more clumsily. Some info on installing BPC under 
CentOS I have has you call up a shell for backuppc, do the key generation and 
copying within that, which is also where I tested the ssh originally.
