Hmmn, Alright. I'll try to add more details. Sorry I wasn't more clear
previously. I had thought I was responding to that thread on the forum
and so left out some details that I felt was already clear in the
forum. But this being put here on the mailing list, I can see how it
seems out of context.
Here's a link to the previous e-mails on this, probably in a more
comfortable format. Just from the archives for this mailing list.

The problem is, I cannot communicate with the BackupPC server. It is
installed and it does run without any errors.
But when I try to run, say..
BackupPC_serverMesg status info
The command just hangs. The strace information I provided shows that
it's hanging when trying to read input from the backuppc daemon.
The strace information on the daemon shows that it never gets any
requests from the client, it sits on the "select" (line 785 of BackupPC
code) command waiting for some sort of input from any of the handlers
and never gets anything. The same is true regardless of connecting via
sockets or tcp.
My limited perl skill mixed with some google searches leads me to
understand that all the input handlers are added up into a variable
called FDread using a "vec" command. Then this value is handed off to
the "select" command where I understand it breaks that FDread variable
back up and listens on all of the given sources. Looking at the bug
report https://dev.openwrt.org/ticket/6900 makes me wonder if some
big/little endian difference is causing the vec or select commands to
add up the values incorrectly and if so, maybe the select command isn't
listening on all (or any) of the input sources.
So, what I'm hoping to find out is rather or not this is really how the
backuppc daemon works and if there's some way to fix the problem.
