wow ... where did you get that version from?
- I must have been asleep when I wrote version 4.4.1. I meant version
4.1.1.

Also without extraenous output? You seem to be using rsync over ssh, and rsync
is quite fussy about messages that it does not expect. As a rule of thumb, to a
*Linux* computer,
% ssh clientcomputer true
%
should immediately display the next prompt as indicated above, i.e. nothing
extra, not even blanks or newlines. For Windoze, your mileage may vary, but it
probably won't. The actual invokation used by BackupPC (or rather rsync_bpc)
might include extra options to ssh, e.g. -q -x -l someuser ... include those
when testing.
- Correct, Holger. I am using rsync over ssh and ssh seems to work
without a problem. When I run the test you suggested: "$ssh targetcomputer
true", I merely get the prompt in response "$". Strace seems to confirm that
ssh is working correctly as when I ssh into the targetcomputer from the command
line, and while running running strace on the targetcomputer, all seems to work
as expected. In addition, when I rsync into the targetcomputer from the
command line, rsync appears to work just fine.
However, when I use the backuppc program to rsync into the very same
targetcomputer, I get the Unexplained Error Code 255 message. Below shows the
ssh strace when I started a manual backuppc backup of some files on the
targetcomputer, if that helps. My log level is up to 9, but not much
information is being generated. I am unclear of how to diagnose as I am not
that versed in linux. Any help would be appreciated. Thanks. Akibu.
