Akibu,
What output do you get when you run this command (replace -q with -v, and
redirect stdin from /dev/null):
/usr/bin/ssh -v -x -l root akibu-desktop /usr/bin/rsync --server --sender
-svvvlHogDtprce.iLsf < /dev/null

Akibu,
It looks like the connection terminates immediately. We need to figure out why.
If you run the exact ssh command as the backuppc user, do you get an error or
any output?
su backuppcUser
/usr/bin/ssh -q -x -l root akibu-desktop /usr/bin/rsync --server --sender
-svvvlHogDtprce.iLsf
If you don't see any output, hit ^D and you should get an error like this:
rsync: on remote machine: (null): unknown option
rsync error: syntax or usage error (code 1) at main.c(1634) [server=3.1.1]
[server] _exit_cleanup(code=1, file=main.c, line=1634): about to call exit(1)
Next, are you sure that the directory /mnt/j/Favorites on akibu-desktop exists?

What we are missing is the log output from XferLOG. That has the more detailed

Hi,
Akibu Flash wrote on 2017-05-29 05:27:04 +0000 [Re: [BackupPC-users]
Unexplained Error Code 255 – BackupPC]:
[…] I am running backuppc version 4.41 on a Debian computer.
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.
When I start a backup, it appears to properly connect to my Windows computer
and then gives me an error message. ?Got fatal error
during
xfer (rsync error: error in rsync protocol data stream (code 12) at io.c(629)
[Receiver=3.0.9.6])? […] Please note that I am able to
ssh
and rsync into the Windows computer manually from the linux computer
^^^^^^^^
without problem.
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.

What, exactly, are you trying to resolve? I suspect you've gotten no answer
because many people looked and said, well, that's obvious, don't back up the
/dev directory, because it's dynamically created. While you're at it, don't
back up /proc, /sys, or /tmp.
