Hi.

If you wish to forward messages using multiple displays you should
change a couple of things, revert the configuration files
(hobbitlaunch.cfg) to make hobbit act as a display server then you
should change hobbitserver.cfg as follows:
BBDISP="0.0.0.0"
BBDISPLAYS="$BBSERVERIP 12.34.56.78"

The BS ip should be changed to whatever the ip is for your main hobbit
server.

This configuration *should* work. Just reply if it doesn't.

With regards,
  Sigurdur Gudbrandsson

The more I read through the archives, the more confused I am on how to
implement this. Basically, I want to monitor 64 compute nodes that are
on a private network. I do not want to have to install the client on
all of the nodes as all I care about is the ping test. I have a main
hobbit server that I want to merge the info from the cluster and from
various other systems that I monitor. 

To work as a bridge, I installed hobbit on the head node of the
cluster as it is the only system with an interface on both networks.
On the head node I disabled all of the hobbitd modules and setup
bbproxy to forward messages to my main hobbit server. This didn’t
work. After reading up on the bbproxy man page it looks like bbproxy
is really meant to forward client messages on to a bbdisplay. Since I
don’t have the hobbit client installed on the compute nodes it doesn’t
sound like bbproxy will work for this. I am a bit confused on what
actually does the network tests. Do I have to have hobbitd running on
the head node in order for the network tests to run? If that is the
case, how do I get hobbitd to forward information on to a different
hobbit server? 

I am pretty sure that I have simply failed to understand one of the
man pages or something, but I cant seem to figure out how to
accomplish what I am looking to do.
