Thank you for your answer but let me rephrase the question.
I have "Maximum Network Buffer Size = 65536" in bacula-fd.conf in the
machine where the tape drive, bacula-dir.conf and bacula-sd.conf are,
but Maximum Network Buffer Size in bacula-fd.conf in the client machines
is set with the default value of 32768.
That setting is important only for the setup of the network connection
on the respective hosts. The Bacula core itself isn't concerned with it,
it's just a setting to fine-tune the network stack of the OS to the
expected work.
Now, does it matter that the two values are different or bacula takes
into account only the value of the configuration file where the tape
drive is?
Each daemon takes into account it's own setting. Typically, these values
can't be incompatible (from Baculas point of view), because the network
stack works around too small or large values, but finding the right
value allows better performance than values that don't fit to the rest
of your setup.
Please let me know if the question is not clear enough.
I can't explain things better - if you need more details you'll have to
read through baculas code and the manuals of your OS, I guess.
Arno
Thanks,
Maurizio

Hi,
It might be a silly question but does the directive "Maximum Network
Buffer Size = <bytes>" need to be set in any bacula-fd.conf (I mean all
clients) or only in the machine where the tape drive reside?
That's a question of network tuning, and to my experience the effects of
different settings depend on lots of factors: Network load, network
adapter hardware, machine load, switches, and all the other things you
can tune in a network stack.
I think you will either have to try different settings, or ask someone
with a really good knowledge about your OSes and hardware and,
especially, network systems.

Thanks,
