My head hurts! Can anyone help me with what follows - it shows ssh working with pki auth in all the permutations I thought might be possible, but lastly this command prompts for a password: # ssh -t rsync@xxxxxxxxxxxx sudo rsync -avzAXHn --delete-after root@xxxxxxxxxxxxx:/etc /media/bigdisk/morgansmachine/etc ... Permission denied (publickey,gssapi-with-mic,password). [root@morgansoldmachine /]# ssh rsync@xxxxxxxxxxxx Last login: Sun Feb 15 20:29:39 2009 from morgansoldmachine.lan [rsync@morgansmachine ~]$ logout Connection to 192.168.1.40 closed.
