Hi there,

The fact that you have one of your IP addresses appearing some place it
probably shouldn't be makes me wonder if you've made a typo in a
configuration file, but I couldn't swear to it.

DW>> I thought that way too and have been racking my brain looking at the
files to see if anything missing or extraneous but just don't see it.  And
it is interesting because I have both an RSYNCD and SMB host running just
fine ..... might just have to give up on RSYNC and go back to SMB for all
the backups. <<<

Looks like you might have installed BackupPC from more than one, er, source.
In the interests of their own sanity, package maintainers for the likes of
Debian, Ubuntu and derivative distributions do (shall we say) interesting
things with the files and directories used 'upstream' by the authors of the
packages (....)

DW>> Since this was a brand new, clean system I don't think I messed up the
install process ... very careful in doing the system install followed by the
few other programs we use (Calibre, etc).  And the BackupPC was directly
from the UBUNTU software app.   I don't think it is a problem either, just
curious I guess .... <<<

Your rsync problem _probably_ isn't related to this issue.  I've seen a few
problems when newer rsyncs wouldn't talk to older ones because of the lack
of (default) shared encryption mechanisms.  This happens especially when you
work with more than one system or distribution or release of same, and some
of them aren't as up to date as the others for perhaps perfectly good
reasons.  Same thing happened with SSH too.

DW>>> That's my biggest concern too -- the versioning and differences
between the systems.  And yet the debug info shows the two talking back and
forth, exchanging keys, etc and then finally being "connected".   It is only
when the rsync-bpc code tries to hand over the next "command" that it is
somehow being started with the IP address ....... <<<<<

Best I can suggest is crank up the debugging levels and log everything you
can until you find something, maybe try using Wireshark too, and don't be
afraid to dig into the code and put some 'print' statements in to add to
what sometimes might be less than informative logging.

DW>>> I have upped the debug level but it only affects the SSH info, not the
rsync-bpc process ... I'm still trying to uncover where the "command" gets
built that ssh is passing over the pipe to the client.  Somehow it is using
either the $host info or the ping info that is associated with the client
and passing it as part of the command.  I tried to look at what is happening
on the older 3.1 backup system with the RSYNC clients but can't get the same
level of debug info -- and of course they are all working just fine.  Would
be great if someone could post their RSYNC log showing the debug level 1
info and what is being passed in the command line ... any takers???  <<<<<

Just my 2 * $currency_units, HTH.  I've glossed over a few things. :/

DW>>>> Appreciate your info and help ... you mentioned using Wireshark ..
have had no experience with it at all -- is it very hard to use and what
would it show me?  And about putting "print" statements into the code --
wouldn't I need to recompile/rebuild the code after that ??  or can I just
put them in the existing code pieces?   <<<<<
