[rdiff-backup-users] remote rdiff-backup refused connection

[Paul Ackerman]

I am having the following message emailed to me by my server

<snip>
Permission denied, please try again.
Permission denied, please try again.
Permission denied (publickey).
Fatal Error: Truncated header string (problem probably originated remotely)

Couldn't start up the remote connection by executing

    ssh -C 192.168.0.253 rdiff-backup --server

Remember that, under the default settings, rdiff-backup must be
installed in the PATH on the remote system.  See the man page for more
information on this.  This message may also be displayed if the remote
version of rdiff-backup is quite different from the local version (0.12.6).
<snip>

Both versions of rdiff-backup are the same 0.12.6. I have reset the keys and
am still being denied permission. Maybe I did not do this correctly. One
machine is running Debian the other redhook (er red hat, obviously my mind
is else where). I am able to ssh from one to the other and back, so these
machines are not denying login permission. I'm stuck , I need this back up
to be working.

Any clues
