setting up multiple servers

Hi,

I m a bit unclear as to the syntax used for the BBDISPLAYS variable.
If I want to set up 2 servers, for redundancy, I set BBDISP to 0.0.0.0, but what is used for separating the servers in BBDISPLAYS ? Just a blank, a comma, ... ?

And on the replicated servers, I guess that I have to modify both server/etc/hobbitserver.cfg and client/etc/hobbitclient.cfg with those same settings ?

Thanks,
Stephane

Correct. Especially, make sure your clients are configured to send data
to both servers.

So, it's up to the clients to send to multiple servers, and the
servers wouldn't forward anything except whatever reports they
generate about themselves??

I *may* have a problem with that in 4.2-RC-20060712.  I have some Big
Brother scripts that are running in a Big Brother environment,
reporting to two Hobbit servers - 4.1.2p1 & 4.2-RC.  Almost all of the
results get through to the RC server, but some don't.

I'm still trying to refine it to a simple test case, but at the moment
it looks like a report with "status+LIFETIME" isn't displayed on the
RC server.  If I remove the +LIFETIME value, the report *is*
displayed.  I figure I must have something wrong, because there have
to be other people using that feature... :)

This may be a tangent to this.  I haven't looked at the DMZ functionality but it seems to me that one could use that to have multiple servers set up....just have them all grab a copy of the client output (set the client up as a DMZ client regardless).   Would this work?

Why not have bbproxy set up on both sides, with hobbitd running on a different 
port, and have each bbproxy forward to both hobbitd's?

I guess with Hobbit 4.2.0, there is no 'etc/hobbitclient.cfg', as it
has been replaced by 'hobbit-clients.cfg' ?


When I configure my two Hobbit servers as discussed below, I see that
there is only one server which lists the 'hobbitd' service.  The other
one ishows ' - '.


Is this normal?  Is the general idea that if both Hobbit servers are
in-sync, that 'hobbitd' on a per-system basis is irrelevant, and so it
only shows one?

Just re-sending this to engage anyone who may have missed it.   Has no one
come across this?

I have the same issue.  Maybe whatever it is (client?) that sends the data
for bbgen and bbtest (and bbproxy if available) to the other hobbit server
misses out the hobbitd data for some reason?
