I had set up rsync a while ago using an Ubuntu pc to pull frm my N810 and it worked well.

When I upgraded to Diablo I lost my host key.

In trying to find a decent explanation on how to redo the key I could not find the simple instructions I used before.

Does anyone have a good simple link on how to set up the key pairing and rsync?

All the threads here jump around and I could not find anything in the wiki.
