[rdiff-backup-users] problems with unattended backup

[Carlos Costa Portela]

   Hello all!

   I'm using rdiff-backup, and all runs ok, but I cannot do unattended 
backup. I've read the doc at 
http://www.arctic.org/~dean/rdiff-backup/unattended.html (excellent doc, 
btw), without luck. Here is the output of the ssh -C command:
